In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)).

The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0032] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), output sound through the sound output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0033] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0034] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) with an external electronic device (e.g., the electronic device (102)).

[0039] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0040] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0041] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0042] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas by, for example, the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0043] According to various embodiments, the antenna module (197) may form a mmWave antenna module. According to one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0044] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0045] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0046] A wearable device connected to the electronic device (101) of FIG. 1 and communicating with the electronic device (101) can be worn on a body part of a user. For example, the wearable device can be worn on the user's finger. For example, the wearable device to be worn on the finger can have a ring shape. For example, the wearable device that can be worn on the finger can be charged using an electronic device for charging the wearable device. For example, the electronic device can always perform (or attempt to perform) charging regardless of the position of the wearable device when the cover (or lid) of the electronic device is opened. When the wearable device is positioned (or seated, coupled, in contact with, or adjacent to) the charging portion of the electronic device, the electronic device can start charging the wearable device using the characteristics of magnetic resonance based on changes in power. For example, initiating or performing said charging may include the electronic device providing power to the wearable device based on a particular voltage.

[0047] As described above, in the wearable device worn on a finger and the electronic device for charging the same, the magnetic resonance-based charging (hereinafter, magnetic resonance method) may require a coil (or antenna) of a relatively large size compared to the magnetic induction-based charging (hereinafter, magnetic induction method). In addition, the coil for the magnetic resonance method may be used for charging, but cannot be used for communication with other electronic devices. In other words, when the electronic device for charging the wearable device uses the magnetic resonance method, in addition to the coil for charging the wearable device, a separate antenna for communicating with the wearable device is required. However, since it further includes a separate antenna and a circuit (or IC (integrated circuitry)) for the communication as described above, the size of the electronic device may increase or there may be insufficient space inside the electronic device.

[0048] In addition, a wearable device worn on the ear (or external auditory canal) may utilize an electronic device for charging the wearable device. At this time, the electronic device may utilize both wired charging and wireless charging to charge the battery of the electronic device. However, the electronic device may utilize wired charging based on contact with an electrode located within a space within the electronic device to provide power from the battery to the wearable device worn on the ear (or for charging). As described above, the wired charging between the wearable device and the electronic device utilizes the electrode exposed to the outside of the electronic device, and thus may be susceptible to corrosion and failure due to moisture and air.

[0049] Hereinafter, the present disclosure describes a structure and method of an electronic device (or a charging device, a cradle, or a charging apparatus) for providing power to (or charging) a wearable device worn on a finger. The electronic device according to the present disclosure can charge the battery of the electronic device through wired charging and / or wireless charging. The electronic device according to the present disclosure can perform communication with the wearable device while simultaneously providing power to (or charging) the wearable device using a near field communication (NFC) antenna. For example, the electronic device according to the present disclosure can control charging and communication with the wearable device by changing a mode of the electronic device depending on a state of the electronic device, whether the wearable device is located within the electronic device, or whether charging is being performed for the electronic device. In addition, the electronic device according to the present disclosure can control charging and communication with the wearable device depending on a temperature of the electronic device and / or the wearable device. The electronic device according to the present disclosure can display battery information of the electronic device and / or the wearable device using an emitter of the electronic device.

[0050] As described above, the electronic device according to the present disclosure, which performs charging and communication using a single NFC antenna, can reduce the size of the electronic device and efficiently utilize the space within the electronic device. In addition, the electronic device according to the present disclosure can reduce battery consumption of the electronic device by stopping unnecessary communication, thereby increasing the usage time of the electronic device and the usage time of the wearable device. In addition, the electronic device according to the present disclosure can improve the user's usability of the wearable device by performing priority charging of the wearable device.

[0051] In the following FIGS. 2 to 4c, specific examples of a wearable device and an electronic device (or charging device) for charging the wearable device according to the present disclosure are described.

[0052] FIG. 2 illustrates an exemplary block diagram of a wearable device and an electronic device for charging the wearable device.

[0053] FIG. 2 illustrates an exemplary block diagram of a wearable device (103) worn on a user's body part and an electronic device (105) for charging the wearable device (103). For example, the body part may include a finger or a finger portion (e.g., a joint) of the user. For example, the wearable device (103) may be referred to as a ring or a smart ring.

In the example of FIG. 2, a wearable device (103, e.g., a smart ring) and an electronic device (101, e.g., a smart phone, a mobile terminal) may be connected using the Bluetooth or BLE communication technique. The wearable device (103) of FIG. 2 may be an example of an electronic device (102) connected to the electronic device (101) of FIG. 1.

[0055] Referring to FIG. 2, according to one embodiment, a wearable device (103) may include a processor (201), a second antenna (203, e.g., BT, BLE antenna), a power management integrated circuitry (PMIC) (205), a battery (207), a first antenna (209, e.g., NFC antenna), a communication circuit (211), a low voltage direct current-direct current converter (LDC, low voltage DC-DC converter) (213), and a sensor (217). However, the present disclosure is not limited thereto.

For example, the charging information of the signal (281) may include information indicating the remaining battery amount of the battery (207) of the wearable device (103) (or whether the battery (207) is fully charged). For example, the charging information of the signal (281) may include information indicating a power level requested when charging using NFC.For example, the power level may indicate one of levels between 1 and 9 (e.g., 1, 2, 3). For example, the charging information of the signal (281) may include information related to power when charging using NFC. For example, the information related to power may indicate the power level of the power currently being provided. For example, the charging information of the signal (281) may include a request for provision of the serial number of the electronic device (105) and version information of the firmware.

[0083] For example, a signal (283) provided from an electronic device (105) to a wearable device (103) may include status information and charging information. For example, each of the status information and the charging information of the signal (283) may include information regarding the electronic device (105).

[0084] For example, the status information of the signal (283) may include input information for the input device (267) of the electronic device (105). For example, the input information may include the start, release (or end), and length of input time (or press time) for the input device (267). For example, the status information of the signal (283) may indicate whether the state of the electronic device (105) is closed or open. For example, the status information of the signal (283) may include version information of the firmware of the electronic device (105). For example, the status information of the signal (283) may include information indicating whether the electronic device (105) has entered a power off mode.

[0085] For example, the charging information of the signal (283) may include information indicating whether the wearable device (103) is being charged using power from the battery (253) of the electronic device (105), whether the wearable device (103) is being charged using power provided from a wired interface (291) connected to the electronic device (105), or whether the wearable device (103) is being charged using power provided from a wireless interface (293) connected to the electronic device (105). For example, the charging information of the signal (283) may include information indicating the temperature of the electronic device (105). For example, the information indicating the temperature of the electronic device (105) may indicate whether the temperature of the electronic device (105) is within a normal range, whether the temperature of the electronic device (105) is within a range requiring partial control, or whether the temperature of the electronic device (105) is within a range requiring interruption of power supply (or charging) by the electronic device (105). For example, the charging information of the signal (283) may include battery information of the electronic device (105).

[0086] As described above, each of the status information and the charging information of signal (281) may include at least some of the information or may further include other information. In addition, each of the status information and the charging information of signal (283) may include at least some of the information or may further include other information.

[0087] As described above, specific details regarding the structure of the wearable device (103) are exemplified and described with reference to FIGS. 3A and 3B below. In addition, specific details regarding the structure of the electronic device (105) (or charging device) for charging the wearable device (103) are exemplified and described with reference to FIGS. 4A to 4C below.

[0088] Figure 3a illustrates an example of a perspective view of a wearable device.

[0089] Referring to FIG. 3A, the wearable device (103) of FIG. 2 may include a housing (301) having a first side (311) facing a part of the user's body (e.g., a finger) and a second side (312) opposite the first side (311). For example, the wearable device (103) may include a ring-shaped housing (301). For example, the wearable device (103) may be configured (or formed) in a ring shape.

[0090] For example, the wearable device (103) may be referred to as a wearable device that can be worn by a user. The wearable device (103) may be worn on a part of the user's body (e.g., a finger). For example, the wearable device (103) may be worn on a part of the user's body. For example, the wearable device (103) may be fastened to a part of the user's body. For example, the wearable device (103) may be detachable from a part of the user's body. For example, the wearable device (103) may have a shape corresponding to a part of the user's body in order to be worn on a part of the user's body.

[0091] For example, the wearable device (103) may be worn by the user and thus come into contact with a part of the user's body. For example, the wearable device (103) may be configured to obtain information about the user through a part of the user's body by being worn by the user. For example, the information about the user may include the user's biometric (or health) information. However, the present invention is not limited thereto. For example, the wearable device (103) may provide information about the user through the wearable device (103) and / or an external electronic device (e.g., the electronic device (101) of FIG. 2) connected to the wearable device (103). However, the present invention is not limited thereto.

[0092] For example, at least a portion of the first surface (311) may come into contact with a part of the user's body when the wearable device (103) is worn by the user. For example, the first surface (311) may surround a part of the user's body on which the wearable device (103) is worn. For example, the first surface (311) may cover a part of the user's body on which the wearable device (103) is worn. For example, the first surface (311) may be configured to pressurize a part of the user's body when the wearable device (103) is worn by the user, thereby fastening the wearable device (103) to a part of the body. For example, the first surface (311) may be deformable by a part of the user's body. For example, the wearable device (103) can provide information about the user through the first side (311) based on haptic technology.

[0093] For example, the second surface (312) may form an outer appearance of the wearable device (103) together with the first surface (311). For example, the second surface (312) may form a ring-shaped housing (301) together with the first surface (311). For example, the second surface (312) may be a surface that is spaced apart from a part of the user's body when the wearable device (103) is worn by the user. For example, the first surface (311) may be referred to as an inner circumference surface of the housing (301). The second surface (312) opposite to the first surface (311) may be referred to as an outer circumference surface of the housing (301).

[0094] For example, the second surface (312) may be exposed to the outside when the wearable device (103) is worn by the user. The second surface (312) may be composed of at least one of titanium, stainless steel, and ceramic. The second surface (312) may be composed of a material for protection against external impact and / or scratches. For example, the second surface (312) may be coated with an additional material for protection of the color and / or appearance of the wearable device (103).

[0095] For example, the first side (311) may be composed of the same and / or similar material as the second side (312). For example, at least a portion of the first side (311) may be composed of at least one of a molding material for acquiring data, transparent plastic, and / or glass. For example, at least a portion of the first side (311) may be composed of a metal for identifying a biosignal.

[0096] For example, the wearable device (103) may further include a hole (370) formed by the first surface (311) for passing a part of the user's body through the wearable device (103) when the wearable device (103) is worn by the user. For example, the hole (370) may be penetrated by a part of the user's body when the wearable device (103) is worn by the user. The wearable device (103) may be configured to be fastened to a part of the user's body when the user wears the wearable device (103) by including a hole (370) configured to pass a part of the user's body through the hole.

[0097] For example, the wearable device (103) may further include one or more components between the first side (311) and the second side (312). For example, the wearable device (103) may include a communication circuit, one or more sensors, and / or a processor between the first side (311) and the second side (312). The arrangement of the one or more components will be described later in FIG. 3B.

[0098] Figure 3b illustrates an example of a partial cross-sectional view of a wearable device.

[0099] Referring to FIG. 3B, the wearable device (103) may be formed in a ring shape. For example, the housing (301) of the wearable device (103) may be formed in a ring shape that can be worn on a user's finger. In FIGS. 3A and 3B, a wearable device (103) having a smooth ring shape is illustrated as an example, but the present invention is not limited thereto. For example, the wearable device (103) may be implemented as a housing including a plurality of flat surfaces. For example, a wearable device (103) having a ring shape that does not have a smooth surface may also be understood as an embodiment of the present disclosure.

[0100] For example, a ring-shaped housing (301) may include a first side (311) that comes into contact with a user's body when worn by the user, a second side (312) that is exposed to the outside, and a side surface between the first side (311) and the second side (312). For example, a space for including (or arranging) at least one component may be included between the first side (311) and the second side (312).

[0101] For example, a PCB may be disposed between the first side (311) and the second side (312) of the wearable device (103). For example, at least one processor (310), a communication circuit (320), an acceleration sensor, a gyro sensor, a PPG sensor, a temperature sensor, a memory (340), and / or a PMIC (354) may be disposed on the PCB (351). For example, the PCB (351) may be composed of a rigid region and a flexible region. For example, the rigid region may be referred to as a rigid flexible printed circuit board (RFPCB). For example, the flexible region may be referred to as a flexible printed circuit board (FPCB). For example, the at least one processor (310) may be an example of the processor (201) of FIG. 2. For example, the communication circuit (320) may be an example of the processor (201) and / or the communication circuit (211) of FIG. 2. For example, the memory (340) may be an example of the memory of the wearable device (103) of FIG. 2. For example, the PMIC (354) may be an example of the processor (201) and / or the PMIC (205) of FIG. 2.

[0102] For example, a PPG sensor may include one or more light-emitting circuits (333-1), one or more light-receiving circuits (333-2), and a control circuit (333-3). For example, one or more light-emitting circuits (333-1) and one or more light-receiving circuits (333-2) may be arranged toward the first side (311). For example, the control circuit (333-3) may be arranged toward the second side (312).

[0103] For example, the PMIC (354) may be used to manage power of the wearable device (103). The PMIC (354) may be used to provide (or distribute) power to components requiring power in the wearable device (103). The PMIC (354) may support a wired charging method (e.g., terminal, pogo pin) or a wireless charging method (e.g., wireless power consortium (WPC), NFC) for charging the wearable device (103) through the first antenna (353). For example, the first antenna (353) may be an example of the first antenna (209) of FIG. 2.

[0104] For example, a battery (352) may be placed between the first side (311) and the second side (312) of the wearable device (103). The battery (352) may be configured with at least one battery (or battery pack). For example, the battery (352) may be configured such that at least one battery is connected in series and / or in parallel. For example, the battery (352) may be configured as a flexible battery pack. For example, the battery (352) may be charged and / or discharged as a secondary battery. For example, the material constituting the battery (352) may be configured in various ways. For example, the material constituting the battery (352) may include at least one of lithium ion and mercury. For example, the battery (352) may be an example of the battery (207) of FIG. 2.

[0105] For example, a second antenna (355) may be positioned between the first side (311) and the second side (312) of the wearable device (103). For example, the second antenna (355) may be composed of a single antenna and / or a plurality of segmented antennas. For example, the second antenna (355) may be composed of a part of the housing (301) of the wearable device (103). For example, the second antenna (355) may be electrically connected to the communication circuit (320) via the PCB (351). For example, the second antenna (355) may be an example of the second antenna (203) of FIG. 2.

[0106] In the example of FIG. 3B, the arrangement of the first antenna (353) and the second antenna (355) of the wearable device (103) is merely an example for convenience of explanation, and the present disclosure is not limited thereto. For example, the first antenna (353) of the wearable device (103) may be arranged in an area where the second antenna (355) of FIG. 3B is arranged, and the second antenna (355) of FIG. 3B may be arranged in an area where the first antenna (353) of the wearable device (103) of FIG. 3B is arranged. Alternatively, for example, the first antenna (353) and the second antenna (355) of the wearable device (103) may be arranged in substantially the same area (or adjacent areas). For example, the first antenna (353) and the second antenna (355) may each be independently connected to the PCB (351), or the first antenna (353) and the second antenna (355) may be connected together with the PCB (351). The connection between the first antenna (353) and the second antenna (355) and the PCB (351) may include an electrical connection.

[0107] Although not illustrated in FIGS. 3A and 3B , the wearable device (103) may include various other components in addition to the illustrated components. For example, the wearable device (103) may include a display. The display may be positioned on the outer surface of the housing (301).

[0108] FIG. 4A illustrates an example of a perspective view of an electronic device for charging a wearable device.

[0109] FIG. 4A illustrates examples (400-1, 400-2) of states (e.g., closed and open states) of the electronic device (105) of FIG. 2. Example (400-1) illustrates a closed state of the electronic device (105). Example (400-2) illustrates an open state of the electronic device (105).

[0110] Referring to FIG. 4A, the electronic device (105) may include a housing forming an exterior of the electronic device (105). For example, the housing may include a first housing part (410) and a second housing part (420) movably coupled to the first housing part (410) between the closed state and the open state. For example, the first housing part (410) may be referred to as a body or a base. For example, the second housing part (420) may be referred to as a lid or a cover.

[0111] Referring to example (400-1), within the closed state of the electronic device (105), the second housing part (420) can be in complete contact with the first housing part (410). Although not illustrated in FIG. 4A, the second housing part (420) and the first housing part (410) can be in contact with each other using a conductive portion having magnetism. Referring to example (400-2), within the open state of the electronic device (105), the second housing part (420) can be at least partially spaced apart from the first housing part (410). In example (400-2) of FIG. 4A, for convenience of explanation, the second housing part (420) is illustrated as being completely spaced apart from the first housing part (410), but the present disclosure is not limited thereto.

[0112] Referring to example (400-2), the first housing part (410) of the electronic device (105) may include a charging portion (430) for charging the wearable device (103). For example, the charging portion (430) may have a post shape so that the ring-shaped wearable device (103) can be positioned (or, contacted, connected, adjacent, fastened). Each of the first housing part (410) and the second housing part (420) of the electronic device (105) is exemplified and described with reference to FIGS. 4B and 4C below.

[0113] Figures 4b and 4c illustrate examples of exploded perspective views of an electronic device for charging a wearable device.

[0114] FIGS. 4b and 4c illustrate examples (405-1, 405-2) of exploded perspective views of the first housing part (410) and the second housing part (420) of the electronic device (105) of FIGS. 2 and 4a.

[0115] Example (405-1) of FIG. 4b illustrates components of a first housing part (410) and components of a second housing part (420) of an electronic device (105). Each of the components of the first housing part (410) and the components of the second housing part (420) is described in more detail through example (405-2).

[0116] Referring to example (405-2) of FIG. 4c, the second housing part (420) may include a cover part (421), a dielectric part (423), connecting members (425-1, 425-2), magnetic materials (427-1, 427-2), and a cushion part (429). The components of the second housing part (420) illustrated in FIGS. 4b and 4c are merely exemplary for convenience of explanation, and the present disclosure is not limited thereto. For example, at least some of the components of the second housing part (420) illustrated in FIGS. 4b and 4c may not be included, or other components may be further included within the second housing part (420).

[0117] For example, the cover portion (421) may form the exterior of the second housing part (420). For example, at least a portion of the cover portion (421) may be formed of a transparent material. For example, the dielectric portion (423) may include a dielectric material to fill the space within the cover portion (421). For example, the dielectric portion (423) may be referred to as a deco.

[0118] For example, the connecting members (425-1, 425-2) may include members for connecting between the first housing part (410) and the second housing part (420). For example, the connecting member (425-1) may be formed with a structure for connecting the second housing part (420) so that it can move relative to the first housing part (410). For example, the connecting member (425-2) may be used to fix the connecting member (425-1) to the second housing part (420).

[0119] For example, the magnetic material (427-1) may be used to detect the state of the electronic device (105) (or the second housing part (420)). For example, the electronic device (105) may identify whether the state of the electronic device (105) is the closed state or the open state by identifying the magnetism of the magnetic material (427-1). As a non-limiting example, the magnetism by the magnetic material (427-1) may be detected by a Hall sensor of the wearable device (103). For example, the magnetic material (427-1) may be referred to as a magnet or a conductive material.

[0120] For example, the magnetic material (427-2) may be used to maintain contact between the second housing part (420) and the first housing part (410). For example, a magnetic material (439-2) corresponding to the magnetic material (427-2) may be included within the first housing part (410). For example, the magnetic material (427-2) may be referred to as a magnet or a conductive material.

[0121] Referring to example (405-2), the first housing part (410) may include an inner cover part (411), a body part (413), an outer cover part (415), a floor part (417), and a buffer part (419). The components of the first housing part (410) illustrated in FIGS. 4B and 4C are merely exemplary for convenience of explanation, and the present disclosure is not limited thereto. For example, at least some of the components of the first housing part (410) illustrated in FIGS. 4B and 4C may not be included, or other components may be further included within the first housing part (410).

[0122] For example, the inner cover portion (411) may be a portion that is covered (or not visible) from the outside of the electronic device (105) by the second housing portion (420) when the electronic device (105) is in the closed state. For example, the space between the inner cover portion (411) and the second housing portion (420) may include a space where the wearable device (103) is positioned within the electronic device (105) for charging. For example, the inner cover portion (411) may include a charging portion (430). The charging portion (430) may include (or be embedded) a first antenna (437, e.g., an NFC antenna). The first antenna (437) may be an example of the first antenna (255) of FIG. 2. For example, the charging portion (430) may include or have a shape of components for positioning, aligning, and fixing the wearable device (103) to the wearable device (103). For example, the charging portion (430) may include a fixing portion (431) for fixing the wearable device (103) positioned on the charging portion (430). For example, an input device (430a) may be included in at least a portion of the inner cover portion (411) or the charging portion (430). For example, the input device (430a) may be included in the input device (267) of FIG. 2. For example, the input device (430a) may be used to input a button (433) from the outside of the electronic device (105). In one example, a wearable device (103) may be charged using a first antenna (437) within the charging portion (430) when the wearable device (103) is positioned on (or in contact with, connected to, or adjacent to) the charging portion (430) of the electronic device (105).

[0123] For example, the inner cover portion (411) may be placed on the body portion (413). For example, the body portion (413) may include a first antenna (437), a button (433), a light-emitting portion (435), and magnetic materials (439-1, 439-2).

[0124] For example, the body portion (413) may include a first antenna (437) to be positioned within a contact portion (430) of the inner cover portion (411) when coupled with the inner cover portion (411). For example, the body portion (413) may include a button (433) to be aligned with an input device (430a) when coupled with the inner cover portion (411). For example, the body portion (413) may include a light emitting portion (435) to be positioned on a lower surface of the inner cover portion (411) when coupled with the inner cover portion (411). For example, light emitted from the light emitting portion (435) may pass through the inner cover portion (411) and be visible from the outside of the electronic device (105). In FIGS. 4B and 4C , the light emitting portion (435) is illustrated as being formed as a circular LED array, but the present disclosure is not limited thereto. For example, the light emitting unit (435) may include LED arrays formed in a circular shape, or may include a plurality of LEDs. Specific examples related to this are illustrated in FIGS. 7A and 7B.

[0125] For example, the magnetic material (439-1) may be used to detect that the wearable device (103) is positioned on the charging portion (430). For example, the electronic device (105) may detect that the wearable device (103) is positioned on the charging portion (430) by identifying the magnetism of the magnetic material (439-1) using a Hall sensor. However, the present disclosure is not limited thereto. For example, the electronic device (103) may not include the magnetic material (439-1).

[0126] For example, a battery (441) of an electronic device (105) may be placed on the lower surface of the body portion (413). For example, the battery (441) may be an example of the battery (253) of FIG. 2. For example, the battery (441) may be placed on a printed circuit board (PCB) (443). For example, a USB port (445) for wired charging may be placed on the PCB (443). For example, the USB port (445) may be an example of the USB port (271) of FIG. 2.

[0127] For example, the floor portion (417) may be connected to the outer cover portion (415). For example, a WPC antenna (447) for wireless charging may be placed on the floor portion (417). For example, the WPC antenna (447) may be an example of the third antenna (273) of FIG. 2. For example, the WPC antenna (447) may include a coil.

[0128] For example, the outer cover portion (415) may form the exterior of the first housing part (410). For example, at least a portion of the outer cover portion (415) may be formed of a transparent material.

[0129] For example, a battery (441), a PCB (443), a USB port (445), and a WPC antenna (447) may be included within a space formed by a body portion (413), an outer cover portion (415), and a floor portion (417). For example, a buffer portion (419) may be arranged on the lower surface of the floor portion (417).

[0130] The electronic device (105) illustrated in FIGS. 4A to 4C is merely an example for convenience of explanation, and the present disclosure is not limited thereto. For example, the electronic device (105) may not include at least some of the components illustrated in FIGS. 4A to 4C , or may further include other components. Furthermore, the positions, shapes, sizes, and numbers of the components of the electronic device (105) illustrated in FIGS. 4A to 4C may be changed.

[0131] Referring to FIGS. 2 to 4C, the electronic device (105) according to the present disclosure can change the mode of the electronic device (105) depending on the state of the electronic device (105) (e.g., closed or open), whether a wearable device (103) is positioned within the electronic device (105), or whether charging is performed on the electronic device (105).

[0132] In the present disclosure, the mode of the electronic device (105) may be set to one of a plurality of modes. For example, the plurality of modes may include a power off mode, a sleep mode, a ping mode, a charging mode, and a charging stop mode.

[0133] For example, the power cutoff mode may be a mode in which the processor (251) of the electronic device (105) is turned off and the IC (261) of the electronic device (105) is turned off. For example, the power cutoff mode may be referred to as an off mode or a first mode. For example, the power cutoff mode may be set (or executed, performed, or changed) when the remaining battery amount of the battery (253) of the electronic device (105) is less than a reference battery amount, when the wearable device (103) is not positioned within the electronic device (105) and the state of the electronic device (105) is closed, or when the wearable device (103) is positioned within the electronic device (105) and the battery of the wearable device (103) is fully charged by charging the battery of the wearable device (103) using the battery (253) of the electronic device (105) and the state of the electronic device (105) is closed. For example, in the case of a battery (253) having the remaining battery amount less than or equal to the reference battery amount, the electronic device (105) may refrain from emitting light from the light-emitting portion (263) of the electronic device (105) (or the light-emitting portion (435) of FIG. 4C). Conversely, in the case of a battery (253) having the remaining battery amount greater than the reference battery amount, the electronic device (105) may emit light from the light-emitting portion (263) of the electronic device (105) (or the light-emitting portion (435) of FIG. 4C).

[0134] For example, the sleep mode may be a mode in which the processor (251) of the electronic device (105) is turned on and the IC (261) of the electronic device (105) is turned off. In other words, the function of the electronic device (105) may be executed, but charging and communication with the wearable device (103) using the first antenna (255) (e.g., NFC antenna) may not be performed. For example, the sleep mode may be referred to as a low power mode or a second mode. For example, the sleep mode may be set (or, executed, performed, or changed) within a closed state of the electronic device (105). For example, compared to the power cut-off mode, the power consumption of the sleep mode may be higher.

[0135] For example, the ping mode, the charging mode, and the charging stop mode may be modes in which the processor (251) of the electronic device (105) is turned on and the IC (261) of the electronic device (105) is at least partially turned on. For example, the ping mode, the charging mode, and the charging stop mode may be referred to as a power on mode.

[0136] For example, the ping mode may be a mode in which the electronic device (105) detects the wearable device (103). For example, the ping mode may be a mode in which the electronic device (105) periodically transmits a signal using the first antenna (255, for example, an NFC antenna) to detect the wearable device (103) while the electronic device (105) is in the open state. For example, the ping mode may be referred to as a detection mode or a third mode. For example, within the ping mode, the signal may be transmitted at a cycle of about 500 ms. For example, within the ping mode, the electronic device (105) may transmit the signal by repeatedly turning the first antenna (255) on and off according to the cycle. For example, the signal transmitted within the ping mode may represent a signal having a specific voltage level (e.g., about 5 V) without including information (or data, packet) included in the signal (283). In other words, the signal within the ping mode may only have a specific voltage level and may not include any information. The ping mode may be used to detect a wearable device (103) with low power consumption.

[0137] For example, the charging mode may be a mode for performing charging and communication for the wearable device (103) using the first antenna (255, e.g., NFC antenna) when the wearable device (103) is detected by the charging portion (430) of the electronic device (105). For example, the charging mode may be used for performing charging and communication for the wearable device (103) until the wearable device (103) is detected by the charging portion (430) of the electronic device (105) and an event instructing to stop charging is detected. For example, the event may include receiving a signal instructing to stop charging (e.g., signal (281)) from the wearable device (103), or the temperature of the electronic device (105) exceeding a reference temperature. For example, the charging mode may be referred to as a charging and communication mode, a power transfer mode, or a fourth mode. For example, within the charging mode, the electronic device (105) can transmit information (or data, packet) included in the signal (283) to the wearable device (103), and the electronic device (105) can receive information (or data, packet) included in the signal (281) from the wearable device (103).

[0138] For example, the charging stop mode may be a mode in which charging of the wearable device (103) using the first antenna (255) is stopped, and communication with the wearable device (103) is periodically performed using the first antenna (255). For example, within the charging stop mode, the electronic device (105) may stop charging the wearable device (103) using the first antenna (255), perform communication during a first time period (e.g., about 0.8 s) among a time period (e.g., about 2.8 s) using the first antenna (255), and stop performing communication during a second time period (e.g., about 2 s) among the time periods. The lengths of each of the time period, the first time period, and the second time period may be adjusted. For example, within the first time interval during the charging stop mode, the electronic device (105) can transmit information (or data, packet) included in the signal (283) to the wearable device (103), and the electronic device (105) can receive information (or data, packet) included in the signal (281) from the wearable device (103). For example, the charging stop mode can be set (or executed, performed, or changed) when the electronic device (105) receives a signal (e.g., signal (281)) indicating a stop of charging from the wearable device (103) while the state of the electronic device (105) is in the open state. For example, the charging stop mode can be referred to as a power hold mode, a settling preparation mode, or a fifth mode.

[0139] FIGS. 5A to 5E illustrate examples of an operational flow for a method of changing a mode of an electronic device for charging a wearable device depending on a state of the electronic device, whether the electronic device is located within the electronic device of the wearable device, or whether charging is being performed on the electronic device.

[0140] At least some of the methods of FIGS. 5A to 5E may be performed by the electronic device (105) of FIG. 2. For example, at least some of the methods may be controlled by the processor (251) of the electronic device (105). In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0141] FIG. 5A may illustrate operations performed by an electronic device (105) depending on the state of the electronic device (105) and whether a wearable device (103) is located within the electronic device (105).

[0142] Referring to FIG. 5A, in operation (501), the electronic device (105) can identify whether the state of the electronic device (105) is open. For example, the electronic device (105) can identify whether the state of the electronic device (105) is the open state or the closed state by using a sensor (265) inside the electronic device (105).

[0143] In operation (501), the electronic device (105) can perform operation (503) if the state of the electronic device (105) is the open state. Conversely, in operation (501), the electronic device (105) can perform operation (505) if the state of the electronic device (105) is the closed state.

[0144] In operation (503), the electronic device (105) may change the mode of the electronic device (105) to the ping mode. For example, the electronic device (105) may detect whether the wearable device (103) is located within the charging portion (430) of the electronic device (105) by periodically transmitting a signal using the first antenna (255). For example, the mode of the electronic device (105) before changing to the ping mode may be the power cut-off mode when the wearable device (103) is not within the electronic device (105). Alternatively, for example, the mode of the electronic device (105) before changing to the ping mode may be the charging mode or the sleep mode when the wearable device (103) is within the electronic device (105).

[0145] In operation (505), the electronic device (105) can determine whether the wearable device (103) is detected. For example, the electronic device (105) can determine whether the wearable device (103) is detected by periodically transmitting a signal using the first antenna (255) within the ping mode.

[0146] In operation (505), the electronic device (105) may perform the method of FIG. 5b if the wearable device (103) is not detected within the open state of the electronic device (105) (or the second housing part (420)). Alternatively, in operation (505), the electronic device (105) may perform the method of FIG. 5c if the wearable device (103) is detected within the open state of the electronic device (105) (or the second housing part (420)).

[0147] In operation (507), the electronic device (105) may determine whether the wearable device (103) is located inside the electronic device (105). For example, the electronic device (105) may determine that the wearable device (105) is not located inside the electronic device (105) if the mode of the electronic device (105) is the power-off mode within the closed state of the electronic device (105) (or the second housing part (420)). For example, the electronic device (105) may determine that the wearable device (105) is located inside the electronic device (105) if the mode of the electronic device (105) is the charging mode or the sleep mode within the closed state of the electronic device (105) (or the second housing part (420)). For example, within the charging mode, the electronic device (105) may determine that the wearable device (103) is located within the electronic device (105) by communicating with the wearable device (103) using the first antenna (255).

[0148] In operation (507), the electronic device (105) may perform the method of FIG. 5d when the wearable device (103) is not positioned within the electronic device (105) in the closed state of the electronic device (105) (or the second housing part (420)). Alternatively, in operation (507), the electronic device (105) may perform the method of FIG. 5e when the wearable device (103) is positioned within the electronic device (105) in the closed state of the electronic device (105) (or the second housing part (420)).

[0149] Referring to FIG. 5B, in operation (511), the electronic device (105) may maintain the mode of the electronic device (105) in the ping mode. For example, the electronic device (105) may maintain the ping mode changed in operation (503). For example, the electronic device (105) may periodically transmit a signal to detect the wearable device (103) within the open state of the electronic device (105). At this time, the wearable device (103) may not be positioned in the charging portion (430) of the electronic device (105).

[0150] Although not shown in FIG. 5b, the electronic device (105) can display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4c).

[0151] In operation (513), the electronic device (105) can determine whether the electronic device (105) is charging. For example, the electronic device (105) can determine whether it is connected to a charging interface (e.g., a wired interface (291) or a wireless interface (293)) for charging the battery (253) of the electronic device (105).

[0152] In operation (513), the electronic device (105) may perform operation (515) if the electronic device (105) is not charging. For example, the case of not charging may include identifying that the electronic device (105) is not connected to the charging interface. Alternatively, for example, the case of not charging may include that the electronic device (105) is fully charged even if the electronic device (105) is connected to the charging interface. Alternatively, in operation (513), the electronic device (105) may perform operation (517) if the electronic device (105) is charging. For example, the case of charging may include identifying that the electronic device (105) is connected to the charging interface.

[0153] In operation (515), the electronic device (105) may maintain the mode of the electronic device (105) in the ping mode. For example, the electronic device (105) may maintain the ping mode changed in operation (503). For example, the electronic device (105) may periodically transmit a signal to detect the wearable device (103) within the open state of the electronic device (105). Although not illustrated in FIG. 5B, when the electronic device (105) maintains the mode of the electronic device (105) in the ping mode, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C). For example, the battery information displayed when the ping mode is maintained may be displayed for a specified period of time.

[0154] In operation (517), the electronic device (105) may determine whether the battery (253) of the electronic device (105) is charged via wired charging. For example, the electronic device (105) may determine that the battery (253) is charged via wired charging when power is provided from the wired interface (291) via the USB port (271). Alternatively, the electronic device (105) may determine that the battery (253) is charged via wireless charging when power is provided from the wireless interface (293) via the third antenna (273, e.g., a WPC antenna).

[0155] In operation (517), if the electronic device (105) determines that the wired charging is performed, it may perform operation (519). In operation (517), if the electronic device (105) determines that the wireless charging is performed, it may perform operation (521).

[0156] In operation (519), the electronic device (105) can perform fast charging. For example, the electronic device (105) can perform the fast charging for the battery (253) of the electronic device (105). For example, the fast charging can be performed according to the wired charging. Although not illustrated in FIG. 5B, the electronic device (105) can display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C) while performing the fast charging.

[0157] In operation (521), the electronic device (105) may perform normal charging. For example, the electronic device (105) may perform the normal charging for the battery (253) of the electronic device (105). For example, the normal charging may indicate charging with a relatively slow charging speed compared to the fast charging. For example, the normal charging may be performed according to the wireless charging. Although not illustrated in FIG. 5B, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C) while performing the normal charging.

[0158] In the above example, the electronic device (105) is described as performing the normal charging according to the wireless charging, but the present disclosure is not limited thereto. For example, the electronic device (105) may perform the normal charging according to the wired charging, and may also perform the fast charging according to the wireless charging.

[0159] In operation (523), the electronic device (105) may determine whether the electronic device (105) is fully charged. In the present disclosure, fully charged may indicate being completely charged. For example, the electronic device (105) may determine whether the battery (253) of the electronic device (105) is fully charged according to the fast charge or the normal charge.

[0160] In operation (523), the electronic device (105) may perform operation (515) if the electronic device (105) is fully charged. For example, the electronic device (105) may maintain the mode of the electronic device (105) in the ping mode. For example, the electronic device (105) may maintain the ping mode changed in operation (503). For example, the electronic device (105) may periodically transmit a signal to detect the wearable device (103) within the open state of the electronic device (105). Although not illustrated in FIG. 5B, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C) to indicate that the electronic device (105) is being charged while periodically transmitting a signal within the ping mode.

[0161] In contrast, in operation (523), the electronic device (105) may perform operation (513) again if the electronic device (105) is not fully charged.

[0162] Referring to FIG. 5C, in operation (531), the electronic device (105) may change the mode of the electronic device (105) to the charging mode. For example, the electronic device (105) may change from the ping mode changed in operation (503) to the charging mode. For example, when the electronic device (105) detects that the wearable device (103) is positioned at the charging portion (430) within the open state of the electronic device (105), the electronic device (105) may perform charging and communication for the wearable device (103) using the first antenna (255, for example, an NFC antenna).

[0163] Although not shown in FIG. 5c, the electronic device (105) can display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4c).

[0164] In addition, although not illustrated in FIG. 5C, the wearable device (103) may provide (or transmit) battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) to an external electronic device (e.g., the electronic device (101) of FIG. 2) connected to the wearable device (103). For example, the battery information of the battery (253) of the electronic device (105) and / or the battery information of the battery (207) of the wearable device (103) provided to the electronic device (101) may be displayed through a display of the electronic device (101) (e.g., the display module (160) of FIG. 1). Specific details related thereto are illustrated and described below with reference to FIGS. 9A to 9C.

[0165] In operation (533), the electronic device (105) can determine whether the electronic device (105) is charging. For example, the electronic device (105) can determine whether it is connected to a charging interface (e.g., a wired interface (291) or a wireless interface (293)) for charging the battery (253) of the electronic device (105).

[0166] In operation (533), the electronic device (105) may perform operation (535) if the electronic device (105) is not charging. For example, the case of not charging may include identifying that the electronic device (105) is not connected to the charging interface. Alternatively, for example, the case of not charging may include that the electronic device (105) is fully charged even if the electronic device (105) is connected to the charging interface. Alternatively, in operation (533), the electronic device (105) may perform operation (537) if the electronic device (105) is charging. For example, the case of charging may include identifying that the electronic device (105) is connected to the charging interface.

[0167] In operation (535), the electronic device (105) can perform charging for the wearable device (103). For example, when the battery (253) of the electronic device (105) is not charged, the electronic device (105) can perform charging and communication for the wearable device (103) using the first antenna (255). Although not shown in FIG. 5C, when performing charging and communication for the wearable device (103), the electronic device (105) can display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C).

[0168] In operation (537), the electronic device (105) may determine whether the battery (253) of the electronic device (105) is charged via wired charging. For example, the electronic device (105) may determine that the battery (253) is charged via wired charging when power is provided from the wired interface (291) via the USB port (271). Alternatively, the electronic device (105) may determine that the battery (253) is charged via wireless charging when power is provided from the wireless interface (293) via the third antenna (273).

[0169] In operation (537), if the electronic device (105) determines that the wired charging is performed, it may perform operation (539). In operation (537), if the electronic device (105) determines that the wireless charging is performed, it may perform operation (541).

[0170] In operation (539), the electronic device (105) may perform charging of the wearable device (103) with priority. For example, the electronic device (105) may perform fast charging of the wearable device (103) and may not perform (or stop, refrain from) charging of the battery (253) of the electronic device (105). For example, the fast charging may be performed according to the wired charging. For example, the electronic device (105) may perform fast charging of the battery (253) of the electronic device (105) when the battery (207) of the wearable device (103) is fully charged (or when charging is completed). Although not shown in FIG. 5c, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4c) while performing the high-speed charging.

[0171] In operation (541), the electronic device (105) can simultaneously perform charging for the wearable device (103) and the electronic device (105). For example, the electronic device (105) can simultaneously perform charging and communication for the wearable device (103) using the first antenna (255) and charging the battery (253) of the electronic device (105). For example, the charging and communication for the wearable device (103) using the first antenna (255) and the charging for the battery (253) of the electronic device (105) can be general charging. Although not shown in FIG. 5c, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4c) while performing the normal charging.

[0172] In the above example, the electronic device (105) is described as performing the normal charging according to the wireless charging, but the present disclosure is not limited thereto. For example, the electronic device (105) may perform the normal charging according to the wired charging, and may also perform the fast charging according to the wireless charging.

[0173] In operation (543), the electronic device (105) can determine whether the wearable device (103) is fully charged. For example, the electronic device (105) can determine whether the battery (207) of the wearable device (103) is fully charged according to the fast charging or the normal charging. For example, the electronic device (105) can determine whether the battery (207) of the wearable device (103) is fully charged by receiving a signal (e.g., signal (281)) while charging and communication with the wearable device (103) are performed using the first antenna (255).

[0174] In operation (543), the electronic device (105) may perform operation (545) if the wearable device (103) is fully charged. For example, the electronic device (105) may change the mode of the electronic device (105) to the charging stop mode to stop charging the wearable device (103). In one example, after changing the mode to the charging stop mode, the electronic device (105) may perform charging of the battery (253) of the electronic device (105) when connected to the wired interface (291) or the wireless interface (293) of the electronic device (105). Alternatively, in operation (543), the electronic device (105) may perform operation (533) again if the electronic device (105) is not fully charged.

[0175] Referring to FIG. 5D, in operation (551), the electronic device (105) may change the mode of the electronic device (105) to the power cutoff mode. For example, the electronic device (105) may change from the ping mode changed in operation (503) to the power cutoff mode. For example, the electronic device (105) may change the power of the processor (251) and the IC (261) of the electronic device (105) to off within the closed state of the electronic device (105). At this time, the wearable device (103) may not be located within the electronic device (105) (or the charging portion (430)).

[0176] In operation (553), the electronic device (105) can determine whether the electronic device (105) is charging.

For example, the electronic device (105) can perform the fast charging for the battery (253) of the electronic device (105). For example, the fast charging can be performed according to the wired charging. Although not illustrated in FIG. 5D, the electronic device (105) can display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C) while performing the fast charging.

[0181] In operation (559), the electronic device (105) may perform normal charging. For example, the electronic device (105) may perform the normal charging for the battery (253) of the electronic device (105). For example, the normal charging may indicate charging with a relatively slow charging speed compared to the fast charging. For example, the normal charging may be performed according to the wireless charging. Although not illustrated in FIG. 5D, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C) while performing the normal charging.

[0182] In the above example, the electronic device (105) is described as performing the normal charging according to the wireless charging, but the present disclosure is not limited thereto. For example, the electronic device (105) may perform the normal charging according to the wired charging, and may also perform the fast charging according to the wireless charging.

[0183] In operation (561), the electronic device (105) can determine whether the electronic device (105) is fully charged. For example, the electronic device (105) can determine whether the battery (253) of the electronic device (105) is fully charged according to the fast charge or the normal charge.

[0184] In operation (561), the electronic device (105) may perform operation (563) if the electronic device (105) is fully charged. For example, the electronic device (105) may maintain the mode of the electronic device (105) in the power cutoff mode. For example, the electronic device (105) may maintain the power cutoff mode changed in operation (551). For example, the electronic device (105) may stop charging and communicating with the wearable device (103) using the first antenna (255) within the power cutoff mode.

[0185] In contrast, in operation (561), the electronic device (105) may perform operation (553) again if the electronic device (105) is not fully charged.

[0186] Referring to FIG. 5E, in operation (571), the electronic device (105) may change the mode of the electronic device (105) to the charging mode. For example, the electronic device (105) may change from the ping mode changed in operation (503) to the charging mode. For example, when the electronic device (105) determines that the wearable device (103) is positioned in the charging portion (430) within the closed state of the electronic device (105), the electronic device (105) may perform charging and communication for the wearable device (103) using the first antenna (255).

[0188] In addition, although not illustrated in FIG. 5e, the wearable device (103) may provide (or transmit) battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) to the electronic device (101) connected to the wearable device (103). For example, the battery information of the battery (253) of the electronic device (105) and / or the battery information of the battery (207) of the wearable device (103) provided to the electronic device (101) may be displayed through a display of the electronic device (101) (e.g., the display module (160) of FIG. 1). Specific details related thereto are illustrated and described below with reference to FIGS. 9a to 9c.

[0189] In operation (573), the electronic device (105) can determine whether the electronic device (105) is charging. For example, the electronic device (105) can determine whether it is connected to a charging interface (e.g., a wired interface (291) or a wireless interface (293)) for charging the battery (253) of the electronic device (105).

[0190] In operation (573), the electronic device (105) may perform operation (575) if the electronic device (105) is not charging. For example, the case of not charging may include identifying that the electronic device (105) is not connected to the charging interface. Alternatively, for example, the case of not charging may include that the electronic device (105) is fully charged even if the electronic device (105) is connected to the charging interface. Alternatively, in operation (573), the electronic device (105) may perform operation (581) if the electronic device (105) is charging. For example, the case of charging may include identifying that the electronic device (105) is connected to the charging interface.

[0191] In operation (575), the electronic device (105) may determine whether an update condition is satisfied. For example, the electronic device (105) may determine whether an update condition for performing an update on the firmware of the electronic device (105) is satisfied. For example, the update condition may be determined by checking whether a signal (e.g., signal (281)) including update information on the firmware of the electronic device (105) is received from the wearable device (103). For example, the signal including the update information on the firmware may be transmitted from the wearable device (103) to the electronic device (105) when the remaining battery amount of the battery (207) of the wearable device (103) exceeds another reference battery amount. At this time, if the latest version of the firmware of the electronic device (105) received from the electronic device (101, e.g., a smart phone) is different from the version of its own firmware received from the electronic device (105), the wearable device (103) may transmit the signal including the update information for the firmware to the electronic device (105). For example, the update information for the firmware may be provided to the wearable device (103) from the electronic device (101) that is connected to the wearable device (103) via wireless communication.

[0192] In operation (575), the electronic device (105) may perform operation (577) if the update condition is satisfied. Alternatively, in operation (575), the electronic device (105) may perform operation (579) if the update condition is not satisfied.

[0193] In operation (577), the electronic device (105) may perform an update of the electronic device (105). For example, the electronic device (105) may perform an update (or change to a latest version) of the firmware of the electronic device (105). As described above, the electronic device (105) may perform the update when the update condition is satisfied without charging the electronic device (105). This may be to perform the update in a stable state so that an error that interrupts the update does not occur.

[0194] In operation (579), the electronic device (105) can charge the wearable device (103). For example, when the battery (253) of the electronic device (105) is not charged, the electronic device (105) can perform charging and communication with the wearable device (103) using the first antenna (255). Although not shown in FIG. 5E, when performing charging and communication with the wearable device (103), the electronic device (105) can display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C).

[0195] In operation (581), the electronic device (105) may determine whether the battery (253) of the electronic device (105) is charged via wired charging. For example, the electronic device (105) may determine that the battery (253) is charged via wired charging when power is provided from the wired interface (291) via the USB port (271). Alternatively, the electronic device (105) may determine that the battery (253) is charged via wireless charging when power is provided from the wireless interface (293) via the third antenna (273).

[0196] In operation (581), if the electronic device (105) determines that the wired charging is performed, it may perform operation (583). In operation (581), if the electronic device (105) determines that the wireless charging is performed, it may perform operation (585).

[0197] In operation (583), the electronic device (105) may perform charging of the wearable device (103) with priority. For example, the electronic device (105) may perform fast charging of the wearable device (103) and may not perform (or stop, refrain from) charging of the battery (253) of the electronic device (105). For example, the fast charging may be performed according to the wired charging. For example, the electronic device (105) may perform fast charging of the battery (253) of the electronic device (105) when the battery (207) of the wearable device (103) is fully charged (or when charging is completed). Although not shown in FIG. 5e, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4c) while performing the high-speed charging.

[0198] In operation (585), the electronic device (105) can simultaneously perform charging for the wearable device (103) and the electronic device (105). For example, the electronic device (105) can simultaneously perform charging and communication for the wearable device (103) using the first antenna (255) and charge the battery (253) of the electronic device (105). For example, the charging for the wearable device (103) and the charging for the battery (253) of the electronic device (105) using the first antenna (255) may be general charging. Although not shown in FIG. 5e, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4c) while performing the normal charging.

[0199] In the above example, the electronic device (105) is described as performing the normal charging according to the wireless charging, but the present disclosure is not limited thereto. For example, the electronic device (105) may perform the normal charging according to the wired charging, and may also perform the fast charging according to the wireless charging.

[0200] In operation (587), the electronic device (105) can determine whether the wearable device (103) is fully charged. For example, the electronic device (105) can determine whether the battery (207) of the wearable device (103) is fully charged according to the fast charging or the normal charging. For example, the electronic device (105) can determine whether the battery (207) of the wearable device (103) is fully charged by receiving a signal (e.g., signal (281)) while charging and communication with the wearable device (103) are performed using the first antenna (255).

[0201] In operation (587), the electronic device (105) may perform operation (589) if the wearable device (103) is fully charged. For example, the electronic device (105) may change the mode of the electronic device (105) to the power cutoff mode or the sleep mode. For example, in operation (573), the electronic device (105) may change the mode of the electronic device (105) to the power cutoff mode if the electronic device (105) is not charged and in operation (579), the electronic device (105) may charge the wearable device (103) using the power of the battery (253) of the electronic device (105) so that the wearable device (103) is fully charged. Alternatively, for example, the electronic device (105) may change the mode of the electronic device (105) to the sleep mode when the wearable device (103) is fully charged by charging the electronic device (105) in operation (573) and using externally provided power to charge the wearable device (103) in operation (583) (or operation (585)). For example, the electronic device (105) may stop charging and communicating with the wearable device (103) using the first antenna (255) in the power cut-off mode or the sleep mode.

[0202] In contrast, in operation (587), the electronic device (105) may perform operation (573) again if the electronic device (105) is not fully charged.

[0203] Although not illustrated in FIG. 5E, the electronic device (105) may determine whether the temperature of the wearable device (103) exceeds a reference temperature when determining that charging of the electronic device (105) is performed in operation (573) and performing charging (e.g., wired charging or wireless charging) of the wearable device (103) in operation (583) or operation (585). For example, the electronic device (105) may stop charging (and communication) to the wearable device (103) upon determining that the temperature of the wearable device (103) exceeds the reference temperature. For example, the electronic device (105) may maintain charging (and communication) to the wearable device (103) upon determining that the temperature of the wearable device (103) is below the reference temperature. For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal requesting to stop charging transmitted when the temperature of the wearable device (103) exceeds a reference temperature. For example, the electronic device (105) may change the mode of the electronic device (105) from the charging mode to the sleep mode. For example, the electronic device (105) may be in the sleep mode for a specified time interval (e.g., 40 seconds). For example, the electronic device (105) may stop charging and communicating with the wearable device (103) using the first antenna (255) during the specified time interval. For example, the electronic device (105) may change the mode of the electronic device (105) from the sleep mode back to the charging mode after the specified time interval. For example, the electronic device (105) may re-perform (or resume) charging and communication with the wearable device (103) using the first antenna (255) within the changed charging mode. In the example, the length of the specified time interval may be adjusted depending on the temperature of the wearable device (103).

[0204] In one example, the electronic device (105) may include a cooling structure (e.g., a fan) to lower the temperature of the wearable device (103) below the reference temperature. For example, the electronic device (105) may drive the cooling structure based on receiving a signal requesting the cessation of charging. Alternatively, in one example, the electronic device (105) may include a structure for heat conduction (e.g., a heat pipe) or a structure penetrating between the exterior of the electronic device (105) and the interior of the electronic device (105) to lower the temperature of the wearable device (103) below the reference temperature.

[0205] Referring to FIGS. 5A to 5E, the electronic device (105) can change the mode of the electronic device (105) and control charging and communication for the wearable device (103) by considering the state of the electronic device (105) (e.g., the closed state and the open state), whether the wearable device (103) is located within the electronic device (105), and whether charging is in progress for the battery (253) of the electronic device (105).

[0206] Hereinafter, in FIGS. 6 to 8c, examples are described of a method in which an electronic device (103) controls charging and communication for a wearable device (103) and displays battery information using a light-emitting unit (263) (or a light-emitting unit (435) of FIG. 4c) according to a more specific usage scenario.

[0207] FIG. 6 illustrates examples of a method for performing charging and communication for a wearable device using a first antenna when an electronic device for charging a wearable device does not receive power from an external source of the electronic device.

[0208] FIG. 6 illustrates examples (601, 602, 603, 604, 605, 606) of a method in which an electronic device (105) performs charging and communication with a wearable device (103) using a first antenna (255) based on power stored within a battery (253) of the electronic device (105). Utilizing power stored within the battery (253) of the electronic device (105) may indicate that the electronic device (105) is not receiving power from an external source (e.g., a wired interface (291) and / or a wireless interface (293)) of the electronic device (105).

[0209] The electronic device (105) of FIG. 6 may be an example of the electronic device (105) of FIG. 2 and the electronic devices (105) of FIGS. 4A to 4C. The wearable device (103) of FIG. 6 may be an example of the wearable device (103) of FIG. 2 and the wearable devices (103) of FIGS. 3A and 3B.

[0210] Referring to FIG. 6, example (601) may represent a case where the electronic device (105) is in the closed state and the wearable device (103) is not positioned within the electronic device (105). Example (602) may represent a case where the electronic device (105) changes from the closed state to the open state. Example (603) may represent a case where the wearable device (103) is detected within the changed open state of the electronic device (105) (or moves from outside the electronic device (105) to the charging portion (430) of the electronic device (105). Example (604) may represent a case where the wearable device (103) is positioned within the electronic device (105) and the electronic device (105) changes from the open state to the closed state. Example (605) may represent a case where a wearable device (103) is positioned within an electronic device (105) and the electronic device (105) changes from the closed state to the open state. Example (606) may represent a case where the wearable device (103) is not detected within the changed open state of the electronic device (105) (or moves from the charging portion (430) of the electronic device (105) to the outside of the electronic device (105).

[0211] Referring to example (601), the electronic device (105) may, within the closed state, refrain from (or, stop, not perform) charging and communication using the first antenna (255). For example, the electronic device (105) may be in the power cutoff mode within the closed state. For example, in the electronic device (105) in the power cutoff mode, both the processor (251) and the IC (261) may be turned off. For convenience of explanation, in FIG. 6, it is assumed that power is charged within the battery (253) of the electronic device (105).

[0212] Referring to example (602), the electronic device (105) can be changed from the closed state to the open state. For example, when the second housing part (420) of the electronic device (105) is separated from the first housing part (410) by an external force (e.g., a change by a user), the state of the electronic device (105) (or the second housing part (420)) can be changed from the closed state to the open state. The electronic device (105) can detect the change from the closed state to the open state using the sensor (265) of the electronic device (105). As a non-limiting example, the electronic device (105) can detect the change from the closed state to the open state by detecting a change in magnetism, a change in light quantity, a change in tension, or an input to a physical button on the electronic device (105) using the sensor (265).

[0213] In example (602), the electronic device (105) may begin to detect, within the open state, whether the wearable device (103) is positioned on (or in contact with, adjacent to, or connected to) the charging portion (430) of the electronic device (105). For example, the electronic device (105) may detect, within the open state, whether the wearable device (103) is positioned on the charging portion (430) by periodically transmitting a signal using the first antenna (255). The electronic device (105) may periodically transmit a signal using the first antenna (255) by changing from the power cut mode to the ping mode. As a non-limiting example, the signal may be transmitted at a specified period (e.g., approximately 500 ms). The signal may not include information (or data, packets).

[0214] Although not shown in Example (602), the electronic device (105) may display battery information of the battery (253) of the electronic device (105) using a light-emitting unit (not shown) of the electronic device (105) (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C) when changing from the closed state to the open state. For example, the electronic device (105) may display the battery information using the light-emitting unit for a specified time period (e.g., about 1 second).

[0215] Referring to example (603), the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430) within the open state. For example, the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430) by periodically transmitting a signal using the first antenna (255). For example, the electronic device (105) can perform charging and communication with the wearable device (103) using the first antenna (255) based on detecting that the wearable device (103) is positioned in the charging portion (430). The electronic device (105) can perform charging and communication with the wearable device (103) using the first antenna (255) by changing from the ping mode to the charging mode.

[0216] Hereinafter, for convenience of explanation, a case in which the electronic device (105) of the above example (603) detects that the wearable device (103) is positioned in the charging portion (430) within the open state, thereby performing charging and communication with the wearable device (103) using the first antenna (255) (or changing from the ping mode to the charging mode) is referred to as case #A.

[0217] Although not illustrated in example (603), when the electronic device (105) detects that the wearable device (103) is positioned in the charging portion (430) within the open state, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using a light-emitting portion (not illustrated) of the electronic device (105) (e.g., light-emitting portion (263) of FIG. 2 or light-emitting portion (435) of FIG. 4C). For example, the electronic device (105) may display battery information using the light-emitting portion for a specified period of time, may continuously display battery information using the light-emitting portion, or may periodically display battery information using the light-emitting portion.

[0218] In example (603), the wearable device (103) may receive battery information of the battery (253) of the electronic device (105) while performing the charging and communication with the electronic device (105). For example, the wearable device (103) may transmit (or provide) battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) to an external electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (103). Accordingly, the external electronic device may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) through a display of the external electronic device. Specific details related thereto are described below with reference to FIGS. 9A to 9C.

[0219] In example (603), the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103) while performing the charging and communication with the wearable device (103). For example, the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103) (e.g., signal (281) of FIG. 2). For example, the signal requesting discontinuation of charging may include information indicating that the battery (207) of the wearable device (103) is fully charged. Accordingly, the electronic device (105) may stop charging the wearable device (103) using the first antenna (255), perform communication with the wearable device (103) using the first antenna (255) during a first time period of the time period, and stop performing communication with the wearable device (103) using the first antenna (255) during a second time period of the time period. In other words, the electronic device (105) may change from the charging mode to the charging stop mode. In the above example, when the wearable device (103) identifies that the battery (207) is full, it may transmit (or provide) information indicating that the battery (207) is full to the external electronic device, and cause the external electronic device to indicate that the battery (207) of the wearable device (103) is full. Additionally, the electronic device (105) can display battery information (e.g., full charge) for the battery (207) of the wearable device (103) using the light-emitting unit (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4c).

[0220] Hereinafter, for convenience of explanation, a case in which the electronic device (105) of the above example (603) receives a signal requesting cessation of charging from the wearable device (103) within the open state (including information indicating that the battery (207) of the wearable device (103) is fully charged), thereby cessating the performance of charging and periodically changing the performance and cessation of communication (or changing from the charging mode to the charging cessation mode) is referred to as case #B.

[0221] Referring to example (604), the electronic device (105) can be changed from the open state to the closed state. For example, when the second housing part (420) of the electronic device (105) comes into contact with the first housing part (410) due to an external force (e.g., a change by a user), the state of the electronic device (105) (or the second housing part (420)) can be changed from the open state to the closed state. The electronic device (105) can detect the change from the open state to the closed state using the sensor (265) of the electronic device (105).

[0222] In example (604), the electronic device (105) can maintain charging and communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state before receiving a signal requesting discontinuation of charging from the wearable device (103). By maintaining the charging mode, the electronic device (105) can perform charging and communication with the wearable device (103) using the first antenna (255).

[0223] For example, in the case #A, the electronic device (105) can maintain charging and communicating with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state. Hereinafter, for convenience of explanation, the case in which the electronic device (105) of the example (604) maintains charging and communicating with the wearable device (103) using the first antenna (255) within the closed state (or maintains the charging mode) is referred to as case #C.

[0224] In example (604), the electronic device (105) may determine whether the temperature of the wearable device (103) exceeds a reference temperature while performing charging and communication with the wearable device (103) using the first antenna (255). For example, the electronic device (105) may stop charging and communication with the wearable device (103) upon determining that the temperature of the wearable device (103) exceeds the reference temperature. For example, the electronic device (105) may maintain charging and communication with the wearable device (103) upon determining that the temperature of the wearable device (103) is below the reference temperature. For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal requesting cessation of charging transmitted when the temperature of the wearable device (103) exceeds the reference temperature. For example, the signal requesting the cessation of charging may include information indicating that the temperature of the wearable device (103) exceeds the reference temperature. For example, the electronic device (105) may stop charging the wearable device (103) upon receiving the signal indicating the cessation of charging (including information indicating that the temperature of the wearable device (103) exceeds the reference temperature) received while performing charging and communication with the wearable device (103) using the first antenna (255) in the case #C. For example, the electronic device (105) may change the mode of the electronic device (105) from the charging mode to the sleep mode. For example, the electronic device (105) may be in the sleep mode for a specified time interval (e.g., 40 seconds). For example, the electronic device (105) may stop charging and communicating with the wearable device (103) using the first antenna (255) during the specified time interval.For example, the electronic device (105) may change the mode of the electronic device (105) back from the sleep mode to the charging mode after the specified time interval (or when the temperature of the wearable device (103) becomes lower than or equal to the reference temperature). For example, the electronic device (105) may re-perform (or resume) charging and communication with the wearable device (103) using the first antenna (255) within the changed charging mode. In the above example, the length of the specified time interval may be adjusted according to the temperature of the wearable device (103). In the above example, a case of resuming once is described, but the present disclosure is not limited thereto. For example, the electronic device (105) may change back from the resumed charging mode to the sleep mode, and then change back from the changed sleep mode to the charging mode.

[0225] In one example, the electronic device (105) may include a cooling structure (e.g., a fan) to lower the temperature of the wearable device (103) below the reference temperature. For example, the electronic device (105) may drive the cooling structure based on receiving a signal requesting the cessation of charging. Alternatively, in one example, the electronic device (105) may include a structure for heat conduction (e.g., a heat pipe) or a structure penetrating between the exterior of the electronic device (105) and the interior of the electronic device (105) to lower the temperature of the wearable device (103) below the reference temperature.

[0226] For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal requesting the stop of charging (including information indicating that the temperature of the wearable device (103) exceeds the reference temperature) while performing charging and communication with the wearable device (103) using the first antenna (255). Hereinafter, for convenience of explanation, the case in which the electronic device (105) of the example (604) stops charging when the temperature of the wearable device (103) exceeds the reference temperature while in the closed state (or changes from the charging mode to the sleep mode for a specified time interval and then changes back to the charging mode) is referred to as case #D.

[0227] In example (604), while performing charging and communication with the wearable device (103) using the first antenna (255), the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103). For example, the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103) (e.g., signal (281) of FIG. 2). For example, the signal requesting discontinuation of charging may include information indicating that the battery (207) of the wearable device (103) is fully charged. Accordingly, the electronic device (105) may stop performing charging and communication with the wearable device (103) using the first antenna (255). For example, the electronic device (105) may stop charging the wearable device (103) upon receiving a signal requesting discontinuation of charging (including information indicating that the battery (207) of the wearable device (103) is fully charged) while performing charging and communication with the wearable device (103) using the first antenna (255) in the case #C. In other words, the electronic device (105) may change from the charging mode to the power cutoff mode. In the example, when the wearable device (103) identifies that the battery (207) is fully charged, it may transmit (or provide) information indicating that the battery (207) is fully charged to the external electronic device, and cause the external electronic device to indicate that the battery (207) of the wearable device (103) is fully charged. Additionally, the electronic device (105) can display battery information (e.g., full charge) for the battery (207) of the wearable device (103) using the light-emitting unit (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4c).

[0228] For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal indicating to stop charging (including information indicating that the battery (207) of the wearable device (103) is fully charged) while performing charging and communication with the wearable device (103) using the first antenna (255). Hereinafter, for convenience of explanation, the case in which the electronic device (105) of the example (604) stops charging (or changes from the charging mode to the power cutoff mode) when the battery (207) of the wearable device (103) is fully charged within the closed state is referred to as case #E.

[0229] In example (604), the electronic device (105) may perform an update on the firmware of the electronic device (105). For example, the electronic device (105) may perform an update on the firmware of the electronic device (105) if an update condition is satisfied. For example, the update condition may be determined by checking whether a signal (e.g., signal (281)) including update information on the firmware of the electronic device (105) is received from the wearable device (103). For example, the signal including the update information on the firmware may be transmitted from the wearable device (103) to the electronic device (105) if the remaining battery amount of the battery (207) of the wearable device (103) exceeds the other reference battery amount. At this time, if the latest version of the firmware of the electronic device (105) received from the electronic device (101) (e.g., a smartphone) is different from the version of the firmware of the electronic device (105) received from the electronic device (105), the wearable device (103) may transmit the signal including the update information for the firmware to the electronic device (105). For example, the update information for the firmware may be provided to the wearable device (103) from the electronic device (101) connected to the wearable device (103). In one example, when the update for the firmware of the electronic device (105) is performed, the update for the firmware of the wearable device (103) may be performed simultaneously. For example, the electronic device (105) may stop charging the wearable device (103) upon receiving a signal indicating discontinuation of charging (including information indicating that the battery (207) of the wearable device (103) is fully charged) while performing charging and communication with the wearable device (103) using the first antenna (255) in the case #C.

[0230] In examples (603) and (604), the electronic device (105) may stop performing communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state after the battery (207) of the wearable device (103) is fully charged. For example, in case #B, the electronic device (105) may stop charging as well as communicating with the wearable device (103) as the electronic device (105) changes from the open state to the closed state. For example, the electronic device (105) may be in the charging stop mode when the electronic device (105) receives a signal (e.g., signal (281)) requesting to stop charging from the wearable device (103) within the open state. The signal requesting the suspension of charging may include information indicating that the wearable device (103) is fully charged. At this time, the electronic device (105) may stop charging the wearable device (103) using the first antenna (255), perform communication with the wearable device (103) using the first antenna (255) during a first time period of the time period, and stop performing communication with the wearable device (103) using the first antenna (255) during a second time period of the time period. Thereafter, the electronic device (105) may further stop performing communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state. In other words, the electronic device (105) may change from the charge suspension mode to the power cutoff mode.

[0231] Hereinafter, for convenience of explanation, a case in which the electronic device (105) of the above example (604) operates in the charge stop mode in the open state and then changes from the charge stop mode to the power cutoff mode by changing to the closed state is referred to as case #F.

[0232] Referring to example (605), the electronic device (105) can be changed from the closed state to the open state. For example, when the second housing part (420) of the electronic device (105) is separated from the first housing part (410) by an external force (e.g., a change by a user), the state of the electronic device (105) (or the second housing part (420)) can be changed from the closed state to the open state. The electronic device (105) can detect the change from the closed state to the open state using the sensor (265) of the electronic device (105).

[0233] In example (605), the electronic device (105) may begin to detect that the wearable device (103) is positioned (or in contact with, adjacent to, or connected to) the charging portion (430) of the electronic device (105) when the electronic device (105) changes from the closed state to the open state. For example, the electronic device (105) may detect whether the wearable device (103) is positioned at the charging portion (430) by periodically transmitting a signal using the first antenna (255) within the open state. In case #E or case #F of example (604), the electronic device (105) that has changed to the power cutoff mode may periodically transmit a signal using the first antenna (255) by changing to the ping mode. Since the wearable device (103) is positioned inside the electronic device (105) and the electronic device (105) changes to the closed state and then changes back to the open state, the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430). For example, the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430) by periodically transmitting a signal using the first antenna (255). For example, the electronic device (105) can perform charging and communication for the wearable device (103) using the first antenna (255) based on detecting that the wearable device (103) is positioned in the charging portion (430). The electronic device (105) can perform charging and communication with the wearable device (103) using the first antenna (255) by changing from the ping mode to the charging mode.

[0234] Alternatively, in example (605), the electronic device (105) may determine that the wearable device (103) is positioned in the charging portion (430) of the electronic device (105) when the electronic device (105) changes from the closed state to the open state. For example, the electronic device (105) may determine that the wearable device (103) is positioned in the charging portion (430) of the electronic device (105) using a signal (e.g., signal (281)) received while performing charging and communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the closed state to the open state in the case #C or the case #D. In example (604), the electronic device (105) in the charging mode may maintain the charging mode.

[0235] Although not illustrated in Example (605), the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using a light-emitting unit (not illustrated) of the electronic device (105) (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C) when changing from the closed state to the open state. For example, the electronic device (105) may display battery information using the light-emitting unit for a specified period of time, continuously display battery information using the light-emitting unit, or periodically display battery information using the light-emitting unit. For example, the wearable device (103) may receive battery information of the battery (253) of the electronic device (105) while performing charging and communication with the electronic device (105). For example, the wearable device (103) can transmit (or provide) battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) to an external electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (103). Accordingly, the external electronic device (e.g., a smart phone) can display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) through a display of the external electronic device.

[0236] Referring to examples (604) and (605), when the electronic device (105) changes from the closed state to the open state while performing an update for the firmware, the electronic device (105) can stop (or cancel) the update and operate based on the current version (or previous version) of the firmware.

[0237] Referring to example (606), the electronic device (105) may begin to detect that the wearable device (103) is positioned on (or in contact with, adjacent to, or connected to) the charging portion (430) of the electronic device (105) based on detecting that the wearable device (103) is not positioned on the charging portion (430) within the open state. For example, the electronic device (105) may detect whether the wearable device (103) is positioned on the charging portion (430) by periodically transmitting a signal using the first antenna (255) within the open state. The electronic device (105) may periodically transmit a signal using the first antenna (255) by changing from the charging mode to the ping mode.

[0238] Although not illustrated in FIG. 6, in example (606), while detecting whether the electronic device (105) is positioned in the charging portion (430) within the open state, the electronic device (105) may detect that the state of the electronic device (105) has changed from the open state to the closed state. For example, when the electronic device (105) changes to the closed state, the electronic device (105) may refrain from (or stop, not perform) charging and communication using the first antenna (255). For example, the electronic device (105) may be in the power cutoff mode within the closed state. For example, in the electronic device (105) in the power cutoff mode, both the processor (251) and the IC (261) may be turned off.

[0239] Cases for charging operations of the electronic device (105), as described in FIG. 6, can be referenced in the table below.

[0240]

[0241] In Table 1, the charging method may indicate a charging method of the battery (253) of the electronic device (105). For example, the single of the charging method may indicate that charging (e.g., wired charging or wireless charging) for the battery (253) is not performed. In Table 1, the cover state may indicate a state of the electronic device (105) or a state of the second housing part (420) of the electronic device (105). For example, the open state of the cover state may indicate the open state of the electronic device (105) (or the second housing part (420)), and the closed state of the cover state may indicate the closed state of the electronic device (105) (or the second housing part (420)). In Table 1, the charging status may indicate whether charging of the battery (253) of the electronic device (105) and / or charging (and communication) of the battery (207) of the wearable device (103) is performed. For example, the charging may indicate that the electronic device (105) uses the first antenna (255) to charge the battery (207) of the wearable device (103). For example, the charging stop may indicate that the electronic device (105) uses the first antenna (255) to stop charging the battery (207) of the wearable device (103). For example, the temperature at the time of the charging stop may indicate that the temperature of the wearable device (103) and / or the electronic device (105) exceeds the reference temperature. For example, when the charging is stopped, the ring full charge may indicate that the battery (207) of the wearable device (103) is fully charged.

[0242] In FIG. 6, it is described that the electronic device (105) detects that the wearable device (103) is positioned in the charging portion (430) by periodically transmitting a signal within the ping mode or transmitting and receiving a signal within the charging mode or the charging stop mode, but the present disclosure is not limited thereto. For example, if the electronic device (105) includes a sensor (e.g., sensor (265) of FIG. 2) for detecting that the wearable device (103) is positioned in the charging portion (430), the electronic device (105) may also detect that the wearable device (103) is positioned in the charging portion (430) using the sensor.

[0243] FIGS. 7A and 7B illustrate examples of a method for displaying battery information of a wearable device and / or an electronic device using a light-emitting portion of an electronic device for charging the wearable device.

[0244] FIGS. 7A and 7B illustrate examples (701, 702, 703, 704, 705, 706, 707, 708, 709, 710) of a method for displaying battery information of a battery (207) of a wearable device (103) and / or battery information of a battery (253) of an electronic device (105) using light-emitting units (435-1, 435-2, 435-3, 435-4, 435-5, 435-6) of an electronic device (105). The light emitting portions (435-1, 435-2, 435-3, 435-4, 435-5, 435-6) of FIGS. 7A and 7B may be examples of the light emitting portion (263) of FIG. 2 and the light emitting portion (435) of FIG. 4C.

[0245] Referring to examples (701, 702, 703) of FIG. 7A, the electronic device (105) can display battery information of the battery (207) of the wearable device (103) and / or battery information of the battery (253) of the electronic device (105) using the light-emitting unit (435-1).

[0246] In example (701), the electronic device (105) can display battery information of a wearable device (103) being charged using a light emitting unit (435-1) including a plurality of LEDs. For example, the plurality of LEDs can include a first LED and a second LED. However, the present disclosure is not limited thereto. For example, the electronic device (105) can display battery information of a wearable device (103) being charged by emitting light (or visible light) having a color (e.g., red (R)) indicating that the battery (207) of the wearable device (103) is being charged using the light emitting unit (435-1) (or the first LED and the second LED).

[0247] In example (702), the electronic device (105) may use a light emitting unit (435-1) including a plurality of LEDs to indicate that the wearable device (103) is performing pairing (e.g., BT connection) with an external electronic device (e.g., electronic device (101) of FIG. 2). For example, the electronic device (105) may use the light emitting unit (435-1) (or the first LED and the second LED) to blink light (or visible light) having a color (e.g., yellow (Y)) indicating that the battery (207) of the wearable device (103) is paired, thereby indicating that the wearable device (103) is performing pairing while charging.

[0248] In example (703), the electronic device (105) can display battery information of a fully charged wearable device (103) by using a light emitting unit (435-1) including a plurality of LEDs. For example, the electronic device (105) can display battery information of a fully charged wearable device (103) by emitting light (or visible light) having a color (e.g., green (G)) indicating that the battery (207) of the wearable device (103) is fully charged by using the first LED of the light emitting unit (435-1).

[0249] In examples (701, 702, 703), the electronic device (105) may display battery information of the electronic device (105) by using a light emitting unit (435-1) including a plurality of LEDs. As a non-limiting example, the electronic device (105) may display battery information of the electronic device (105) by emitting light (or visible light) in a color (e.g., red indicating a low level of remaining battery power, orange indicating a medium level of remaining battery power, or green indicating a full charge) indicating battery information of the battery (253) of the electronic device (105) by using the second LED among the light emitting units (435-1).

[0250] Referring to examples (704, 705, 706) of FIG. 7b, the electronic device (105) can display battery information of the battery (207) of the wearable device (103) and / or battery information of the battery (253) of the electronic device (105) using the light-emitting unit (435-2).

[0251] In example (704), the electronic device (105) can display battery information of a wearable device (103) being charged by using a light emitting unit (435-2) including one LED. For example, the electronic device (105) can display battery information of a wearable device (103) being charged by emitting light (or visible light) having a color (e.g., red) indicating that the battery (207) of the wearable device (103) is being charged by using the light emitting unit (435-2) including one LED.

[0252] In example (705), the electronic device (105) may indicate that the wearable device (103) is performing pairing (e.g., BT connection) with an external electronic device (e.g., electronic device (101) of FIG. 2) by using a light emitting unit (435-2) including one LED. For example, the electronic device (105) may indicate that the wearable device (103) is performing pairing by blinking light (or visible light) having a color (e.g., yellow) indicating that the battery (207) of the wearable device (103) is being paired by using the light emitting unit (435-2) including one LED.

[0253] In example (706), the electronic device (105) can display battery information of a fully charged wearable device (103) using a light emitting unit (435-2) including one LED. For example, the electronic device (105) can display battery information of a fully charged wearable device (103) by emitting light (or visible light) having a color (e.g., green) indicating that the battery (207) of the wearable device (103) is fully charged using the light emitting unit (435-2) including one LED. As a non-limiting example, the electronic device (105) can alternately display battery information of a fully charged wearable device (103) and battery information of the electronic device (105) by emitting light using the light emitting unit (435-2) including one LED.

[0254] In examples (704, 705, 706), the electronic device (105) can display battery information of the wearable device (103) by emitting light using the light emitting portion (435-2) including one LED when the wearable device (103) is positioned in the charging portion (430) of the electronic device (105). Conversely, the electronic device (105) can display battery information of the electronic device (105) by emitting light using the light emitting portion (435-2) including one LED when the wearable device (103) is not positioned in the charging portion (430) of the electronic device (105).

[0255] Referring to example (707) of FIG. 7b, the electronic device (105) can display battery information of the battery (207) of the wearable device (103) and / or battery information of the battery (253) of the electronic device (105) using a light-emitting unit (435-3) including a plurality of LEDs. In example (707) of FIG. 7b, the light-emitting unit (435-3) is illustrated as including four LEDs, but the present disclosure is not limited thereto.

[0256] In example (707), the electronic device (105) can change the number of LEDs that light up as the power stored in the battery (207) of the wearable device (103) increases as charging of the wearable device (103) progresses. For example, the electronic device (105) can light up one LED among four LEDs of the light-emitting unit (435-3) when the power stored in the battery (207) of the wearable device (103) is less than or equal to a first reference battery amount. The electronic device (105) can light up two LEDs among four LEDs of the light-emitting unit (435-3) when the power stored in the battery (207) of the wearable device (103) exceeds the first reference battery amount and is less than a second reference battery amount that exceeds the first reference battery amount. The electronic device (105) can emit light from three of the four LEDs of the light-emitting unit (435-3) when the power stored in the battery (207) of the wearable device (103) exceeds the second reference battery amount and is less than the third reference battery amount that exceeds the second reference battery amount. The electronic device (105) can emit light from all four LEDs of the light-emitting unit (435-3) when the power stored in the battery (207) of the wearable device (103) is fully charged.

[0257] In example (707), the electronic device (105) can display battery information of the wearable device (103) by emitting light using the light emitting portion (435-3) including a plurality of LEDs when the wearable device (103) is positioned in the charging portion (430) of the electronic device (105). Conversely, the electronic device (105) can display battery information of the electronic device (105) by emitting light using the light emitting portion (435-3) including a plurality of LEDs when the wearable device (103) is not positioned in the charging portion (430) of the electronic device (105).

[0258] Referring to examples (708, 709, 710) of FIG. 7B, the electronic device (105) may display battery information of the battery (207) of the wearable device (103) and / or battery information of the battery (253) of the electronic device (105) using light-emitting units (435-4, 435-5, 435-6) including an LED array. For example, the LED array may be configured in a ring shape or a half-ring shape including a plurality of LEDs.

[0259] In example (708), the electronic device (105) can display battery information of the electronic device (105) and battery information of the wearable device (103) using a light-emitting unit (435-4) including a plurality of LED arrays (435a, 435b). Each of the plurality of LED arrays (435a, 435b) of example (708) can have a ring shape. For example, the radius of the first LED array (435a) can be shorter than the radius of the second LED array (435b). However, the present disclosure is not limited thereto. For example, the electronic device (105) can display battery information of the electronic device (105) using the first LED array (435a) of the light-emitting unit (435-4). For example, the electronic device (105) can display battery information of the wearable device (103) using the second LED array (435b) of the light-emitting unit (435-4).

[0260] In example (709), the electronic device (105) can display battery information of the electronic device (105) or battery information of the wearable device (103) using a light-emitting portion (435-5) including one LED array (735a). The LED array (435a) of example (709) can have a ring shape. For example, the electronic device (105) can display battery information of the wearable device (103) by emitting light using the light-emitting portion (435-5) including one LED array (735a) when the wearable device (103) is positioned in the charging portion (430) of the electronic device (105). In contrast, the electronic device (105) can display battery information of the electronic device (105) by emitting light using a light emitting portion (435-5) including one LED array (735a) when the wearable device (103) is not positioned in the charging portion (430) of the electronic device (105).

[0261] In example (710), battery information of the electronic device (105) and battery information of the wearable device (103) can be displayed using a light-emitting unit (435-6) including a plurality of LED arrays (435c, 435d). Each of the plurality of LED arrays (435c, 435d) of example (710) can have a half-ring shape. For example, the radius of the first LED array (435c) can be the same as the radius of the second LED array (435d). However, the present disclosure is not limited thereto. For example, the electronic device (105) can display battery information of the electronic device (105) using the first LED array (435c) of the light-emitting unit (435-6). For example, the electronic device (105) can display battery information of the wearable device (103) using the second LED array (435d) of the light-emitting unit (435-6).

[0262] In examples (708, 709, 710), the electronic device (105) may display the remaining battery amount of the battery (253) of the electronic device (105) and / or the remaining battery amount of the battery (207) of the wearable device (103) by using the length (or, the ratio of light emission, gauge) of the light-emitting LED array of the light-emitting portions (435-4, 435-5, 435-6). For example, the greater the remaining battery amount, the longer the length of light emission of the LED array may be.

[0263] Referring to FIGS. 7A and 7B, the electronic device (105) can display battery information (or remaining battery amount) of the electronic device (105) and / or the wearable device (103) using light-emitting units (435-1, 435-2, 435-3, 435-4, 435-5, 435-6). In one example, the electronic device (105) may display battery information using light emitting elements (435-1, 435-2, 435-3, 435-4, 435-5, 435-6) for a specified time period, or may display battery information continuously using light emitting elements (435-1, 435-2, 435-3, 435-4, 435-5, 435-6), or may display battery information periodically using light emitting elements (435-1, 435-2, 435-3, 435-4, 435-5, 435-6). Additionally, in one example, the electronic device (105) may display battery information (or remaining battery amount) or an object of displayed battery information (e.g., the electronic device (105) or the wearable device (103)) by adjusting the brightness (or luminance) of the light (or visible light) displayed using the light-emitting units (435-1, 435-2, 435-3, 435-4, 435-5, 435-6).

[0264] In FIGS. 7A and 7B , examples are shown in which the electronic device (105) displays battery information (or remaining battery amount) or an object of the displayed battery information (e.g., the electronic device (105) or the wearable device (103)) using the light emitting units (435-1, 435-2, 435-3, 435-4, 435-5, 435-6), but the present disclosure is not limited thereto. For example, the electronic device (105) may further include a display included in the first housing part (410) or the second housing part (420). For example, the electronic device (105) may also display visual information indicating battery information (or remaining battery amount) or an object of the displayed battery information (e.g., the electronic device (105) or the wearable device (103)) on the display. As a non-limiting example, the electronic device (105) may include both the light emitting unit (435-1, 435-2, 435-3, 435-4, 435-5, 435-6) and the display.

[0265] FIG. 8A illustrates examples of a method in which an electronic device for charging a wearable device receives power from an external source of the electronic device.

[0266] FIG. 8A illustrates examples (810, 820) of how an electronic device (105) receives power from an external source of the electronic device (105). For example, the external source of the electronic device (105) may include interfaces (or external electronic devices, charging devices) connected to the electronic device (105). For example, the interfaces may include a wired interface (291) and a wireless interface (293). The electronic device (105) of FIG. 8A may be an example of the electronic device (105) of FIG. 2 and FIGS. 4A to 4C. The wired interface (291) of FIG. 8A may be an example of the wired interface (291) of FIG. 2. The wireless interface (293) of FIG. 8A may be an example of the wireless interface (293) of FIG. 2.

[0267] FIG. 8A illustrates an example (810) of fast charging using a wired interface (291) and an example (820) of normal charging using a wireless interface (293). For example, the normal charging may indicate charging with a relatively slow charging speed compared to the fast charging. For example, the normal charging may be performed according to the wireless charging. In the examples (810, 820) of FIG. 8A, the electronic device (105) is described as performing the normal charging using the wireless interface (293), but the present disclosure is not limited thereto. For example, the electronic device (105) may perform the normal charging using the wired interface (291) and may also perform the fast charging using the wireless interface (293).

[0268] In FIG. 8A, for convenience of explanation, a case is illustrated where the wearable device (103) is not positioned inside the electronic device (105), but the present disclosure is not limited thereto. For example, the wearable device (103) may be positioned in the charging portion (430) of the electronic device (105). When the wearable device (103) is positioned in the charging portion (430), the operations of the electronic device (105) may be referred to with reference to FIGS. 8B and 8C below.

[0269] In example (810), the battery (253) of the electronic device (105) can be charged using power provided through the wired interface (291). For example, when charging using power provided through the wired interface (291), the fast charging of the battery (253) can be performed. For example, while performing the fast charging, the electronic device (105) can display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C). For specific details on a method for the electronic device (105) to perform charging and communication with the wearable device (103) while the electronic device (105) is being charged using the wired interface (291), reference may be made to FIG. 8B below.

[0270] In example (820), the battery (253) of the electronic device (105) can be charged using power provided through the wireless interface (293). For example, when charging using power provided through the wireless interface (293), the normal charging of the battery (253) can be performed. For example, while performing the normal charging, the electronic device (105) can display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C). For specific details on a method for the electronic device (105) to perform charging and communication with the wearable device (103) while the electronic device (105) is being charged using the wireless interface (293), reference may be made to FIG. 8C below.

[0271] FIG. 8B illustrates examples of a method for performing charging and communication for a wearable device using a first antenna when an electronic device for charging a wearable device receives power from outside the electronic device through wired charging.

[0272] FIG. 8B illustrates examples (811, 812, 813, 814, 815, 816) of how an electronic device (105) performs charging and communication with a wearable device (103) using a first antenna (255) based on power provided through a wired interface (291).

[0273] The electronic device (105) of FIG. 8B may be an example of the electronic device (105) of FIG. 2 and the electronic devices (105) of FIGS. 4A to 4C. The wearable device (103) of FIG. 8B may be an example of the wearable device (103) of FIG. 2 and the wearable devices (103) of FIGS. 3A and 3B. The wired interface (291) of FIG. 8B may be an example of the wired interface (291) of FIG. 2.

[0274] Referring to FIG. 8B, example (811) may represent a case where the electronic device (105) is in the closed state and the wearable device (103) is not positioned within the electronic device (105). Example (812) may represent a case where the electronic device (105) changes from the closed state to the open state. Example (813) may represent a case where the wearable device (103) is detected within the changed open state of the electronic device (105) (or moves from outside the electronic device (105) to the charging portion (430) of the electronic device (105). Example (814) may represent a case where the wearable device (103) is positioned within the electronic device (105) and the electronic device (105) changes from the open state to the closed state. Example (815) may represent a case where a wearable device (103) is positioned within an electronic device (105) and the electronic device (105) changes from the closed state to the open state. Example (816) may represent a case where the wearable device (103) is not detected within the changed open state of the electronic device (105) (or moves from the charging portion (430) of the electronic device (105) to the outside of the electronic device (105).

[0275] Referring to example (811), the electronic device (105) may refrain from (or stop, not perform) charging and communication using the first antenna (255) within the closed state. For example, the electronic device (105) may be in the power cutoff mode within the closed state. For example, in the electronic device (105) in the power cutoff mode, both the processor (251) and the IC (261) may be turned off. As described in example (810) of FIG. 8A, in example (811), the electronic device (105) may charge the battery (253) of the electronic device (105) based on the power provided through the wired interface (291). For example, when the wired interface (291) is used, fast charging of the battery (253) may be performed. For example, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C) while performing the fast charging. For example, the battery (253) may be in a charging or fully charged state.

[0276] Referring to example (812), the electronic device (105) can be changed from the closed state to the open state. For example, when the second housing part (420) of the electronic device (105) is separated from the first housing part (410) by an external force (e.g., a change by a user), the state of the electronic device (105) (or the second housing part (420)) can be changed from the closed state to the open state. The electronic device (105) can detect the change from the closed state to the open state using the sensor (265) of the electronic device (105). As a non-limiting example, the electronic device (105) can detect the change from the closed state to the open state by detecting a change in magnetism, a change in light quantity, a change in tension, or an input to a physical button on the electronic device (105) using the sensor (265).

[0277] In example (812), the electronic device (105) may begin to detect, within the open state, whether the wearable device (103) is positioned on (or in contact with, adjacent to, or connected to) the charging portion (430) of the electronic device (105). For example, the electronic device (105) may detect, within the open state, whether the wearable device (103) is positioned on the charging portion (430) by periodically transmitting a signal using the first antenna (255). The electronic device (105) may periodically transmit a signal using the first antenna (255) by changing from the power cut mode to the ping mode. As a non-limiting example, the signal may be transmitted at a specified period (e.g., approximately 500 ms). The signal may not include information (or data, packets).

[0278] Although not illustrated in Example (812), the electronic device (105) may display battery information of the battery (253) of the electronic device (105) using a light-emitting unit (not illustrated) (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C) when changing from the closed state to the open state. For example, the electronic device (105) may display the battery information using the light-emitting unit. Unlike Example (602) of FIG. 6, while being charged using the wired interface (291), the electronic device (105) may maintain displaying the battery information using the light-emitting unit (or continuously display the battery information over time).

[0279] Referring to example (813), the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430) within the open state. For example, the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430) by periodically transmitting a signal using the first antenna (255). For example, the electronic device (105) can perform charging and communication for the wearable device (103) using the first antenna (255) based on detecting that the wearable device (103) is positioned in the charging portion (430). The electronic device (105) can perform charging and communication for the wearable device (103) using the first antenna (255) by changing from the ping mode to the charging mode. In example (813), the electronic device (105) may stop fast charging of the battery (253) of the electronic device (105) and perform fast charging of the battery (207) of the wearable device (103). In order to recycle the wearable device (103) more quickly, the electronic device (105) may stop fast charging of the battery (253) of the electronic device (105) using the wired interface (291) and perform fast charging of the battery (207) of the wearable device (103) using the wired interface (291). Hereinafter, stopping fast charging of the battery (253) of the electronic device (105) using the wired interface (291) and performing fast charging of the battery (207) of the wearable device (103) using the wired interface (291) may be referred to as standalone charging of the wearable device (103).

[0280] Hereinafter, for convenience of explanation, when the electronic device (105) of the example (813) detects that the wearable device (103) is positioned in the charging portion (430) within the open state, thereby performing charging and communication with the wearable device (103) using the first antenna (255) (or changing from the ping mode to the charging mode), this is referred to as case #G.

[0281] Although not shown in example (813), when the electronic device (105) detects that the wearable device (103) is positioned in the charging portion (430) within the open state, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using a light-emitting portion (not shown) of the electronic device (105) (e.g., light-emitting portion (263) of FIG. 2 or light-emitting portion (435) of FIG. 4C). Unlike example (602) of FIG. 6, while being charged using a wired interface (291), the electronic device (105) may maintain displaying (or continuously displaying) the battery information using the light-emitting portion.

[0282] In example (813), the wearable device (103) may receive battery information of the battery (253) of the electronic device (105) while performing the charging and communication with the electronic device (105). For example, the wearable device (103) may transmit (or provide) battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) to an external electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (103). Accordingly, the external electronic device may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) through a display of the external electronic device. Specific details related thereto are described below with reference to FIGS. 9A to 9C.

[0283] In example (813), the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103) while performing the charging and communication with the wearable device (103). For example, the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103) (e.g., signal (281) of FIG. 2). For example, the signal requesting discontinuation of charging may include information indicating that the battery (207) of the wearable device (103) is fully charged. Accordingly, the electronic device (105) may stop charging the wearable device (103) using the first antenna (255), perform communication with the wearable device (103) using the first antenna (255) during a first time period of the time period, and stop performing communication with the wearable device (103) using the first antenna (255) during a second time period of the time period. In other words, the electronic device (105) may change from the charging mode to the charging stop mode. In the above example, when the wearable device (103) identifies that the battery (207) is full, it may transmit (or provide) information indicating that the battery (207) is full to the external electronic device, and cause the external electronic device to indicate that the battery (207) of the wearable device (103) is full. Additionally, the electronic device (105) can display battery information (e.g., full charge) for the battery (207) of the wearable device (103) using the light-emitting unit (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C). While being charged using the wired interface (291), the electronic device (105) can maintain displaying (or continuously displaying) the battery information using the light-emitting unit.

[0284] In example (813), the electronic device (105) may stop fast charging of the battery (207) of the wearable device (103) and perform fast charging (or standalone charging) of the battery (253) of the electronic device (105). For example, the electronic device (105) may perform fast charging (or standalone charging) of the battery (253) of the electronic device (105) using the wired interface (291) as fast charging of the battery (207) of the wearable device (103) using the wired interface (291) is stopped.

[0285] Hereinafter, for convenience of explanation, a case in which the electronic device (105) of the above example (813) receives a signal requesting cessation of charging from the wearable device (103) within the open state (including information indicating that the battery (207) of the wearable device (103) is fully charged), thereby cessating charging and periodically changing the performance and cessation of communication (or changing from the charging mode to the charging cessation mode) is referred to as case #H. In case #H, the electronic device (105) can perform fast charging (or standalone charging) of the battery (253) of the electronic device (105) using the wired interface (291).

[0286] In example (813), when both the battery (207) of the wearable device (103) and the battery (253) of the electronic device (105) are fully charged, the electronic device (105) may stop the fast charging (or standalone charging) using the wired interface (291) and maintain the charging stop mode. For example, after the electronic device (105) stops the fast charging (or standalone charging) for the electronic device (105) using the wired interface (291), the electronic device (105) may stop charging the wearable device (103) using the first antenna (255), perform communication with the wearable device (103) using the first antenna (255) during a first time period of the time period, and stop performing communication with the wearable device (103) using the first antenna (255) during a second time period of the time period. For convenience of explanation, in the following, the electronic device (105) of the above example (813) is referred to as case #I when the battery (253) of the electronic device (105) is also fully charged (or, when the charging interruption mode is maintained) in case #H.

[0287] Referring to example (814), the electronic device (105) can be changed from the open state to the closed state. For example, when the second housing part (420) of the electronic device (105) comes into contact with the first housing part (410) due to an external force (e.g., a change by a user), the state of the electronic device (105) (or the second housing part (420)) can be changed from the open state to the closed state. The electronic device (105) can detect the change from the open state to the closed state using the sensor (265) of the electronic device (105).

[0288] In example (814), if the electronic device (105) changes from the open state to the closed state before receiving a signal requesting discontinuation of charging from the wearable device (103), the electronic device (105) can maintain charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255). By maintaining the charging mode, the electronic device (105) can perform charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255). For example, the electronic device (105) can maintain charging (or standalone charging) and communication with the wearable device (103) using the wired interface (291).

[0289] For example, in the case #G, the electronic device (105) can maintain charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state. Hereinafter, for convenience of explanation, the case in which the electronic device (105) of the example (814) maintains charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255) in the closed state (or maintains the charging mode) is referred to as case #J.

[0290] In example (814), the electronic device (105) may determine whether the temperature of the wearable device (103) exceeds a reference temperature while performing charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255). For example, the electronic device (105) may stop charging (or standalone charging) and communication with the wearable device (103) upon determining that the temperature of the wearable device (103) exceeds the reference temperature. For example, the electronic device (105) may maintain charging (or standalone charging) and communication with the wearable device (103) upon determining that the temperature of the wearable device (103) is below the reference temperature. For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal requesting to stop charging transmitted when the temperature of the wearable device (103) exceeds a reference temperature. For example, the signal requesting to stop charging may include information indicating that the temperature of the wearable device (103) exceeds the reference temperature. For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal instructing to stop charging (including information indicating that the temperature of the wearable device (103) exceeds the reference temperature) received while performing charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255) in the case #J. For example, the electronic device (105) may change the mode of the electronic device (105) from the charging mode to the sleep mode. For example, the electronic device (105) may be in the sleep mode for a specified time interval (e.g., 40 seconds). For example, the electronic device (105) may stop charging (or solely charging) and communicating with the wearable device (103) using the first antenna (255) during the specified time interval.For example, the electronic device (105) may change the mode of the electronic device (105) from the sleep mode back to the charging mode after the specified time interval. For example, the electronic device (105) may re-perform (or resume) charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255) within the changed charging mode. In the above example, the length of the specified time interval may be adjusted according to the temperature of the wearable device (103). In the above example, a case of resuming once is described, but the present disclosure is not limited thereto. For example, the electronic device (105) may change from the resumed charging mode back to the sleep mode, and then change from the changed sleep mode back to the charging mode.

[0291] In one example, the electronic device (105) may include a cooling structure (e.g., a fan) to lower the temperature of the wearable device (103) below the reference temperature. For example, the electronic device (105) may drive the cooling structure based on receiving a signal requesting the cessation of charging. Alternatively, in one example, the electronic device (105) may include a structure for heat conduction (e.g., a heat pipe) or a structure penetrating between the exterior of the electronic device (105) and the interior of the electronic device (105) to lower the temperature of the wearable device (103) below the reference temperature.

[0292] For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal requesting the stop of charging (including information indicating that the temperature of the wearable device (103) exceeds the reference temperature) while performing charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255). For convenience of explanation, in the following, the case where the electronic device (105) of the example (814) stops charging when the temperature of the wearable device (103) exceeds the reference temperature while in the closed state (or changes from the charging mode to the sleep mode for a specified time interval and then changes back to the charging mode) is referred to as case #K.

[0293] In example (814), while performing charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255), the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103). For example, the electronic device (105) may receive a signal requesting discontinuation of charging (e.g., signal (281) of FIG. 2) from the wearable device (103). For example, the signal requesting discontinuation of charging may include information indicating that the battery (207) of the wearable device (103) is fully charged. Accordingly, the electronic device (105) may stop performing charging and communication with the wearable device (103) using the first antenna (255). For example, the electronic device (105) may, in the case #J, stop charging the wearable device (103) upon receiving a signal requesting the stop of charging (including information indicating that the battery (207) of the wearable device (103) is fully charged) while performing charging (or standalone charging) and communication with the wearable device (103) using the first antenna (255). In other words, the electronic device (105) may change from the charging mode to the sleep mode. For example, the electronic device (105) may stop charging (or standalone charging) and communication with the wearable device (103) using the wired interface (291) and then perform charging (or standalone charging) of the electronic device (105) using the wired interface (291). Unlike case #E of FIG. 6, when a wearable device (103) is positioned within the electronic device (105), the electronic device (105) can change from the charging mode to the sleep mode, rather than changing from the charging mode to the power cut-off mode.

[0294] In the above example, when the wearable device (103) identifies that the battery (207) is fully charged, it can transmit (or provide) information indicating that the battery (207) is fully charged to the external electronic device, and cause the external electronic device to indicate that the battery (207) of the wearable device (103) is fully charged. In addition, the electronic device (105) can display battery information (e.g., full charge) about the battery (207) of the wearable device (103) using the light-emitting unit (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C).

[0295] For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal indicating to stop charging (including information indicating that the battery (207) of the wearable device (103) is fully charged) while performing charging and communication with the wearable device (103) using the first antenna (255). Thereafter, the electronic device (105) may perform charging of the electronic device (105) using the wired interface (291). For convenience of explanation, in the following, a case in which the electronic device (105) of the example (814) stops charging when the battery (207) of the wearable device (103) is fully charged in the closed state and performs charging of the battery (253) of the electronic device (105) (or changes from the charging mode to the sleep mode) is referred to as case #L.

[0296] In examples (813) and (814), the electronic device (105) may stop performing communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state after the battery (207) of the wearable device (103) is fully charged. For example, in case #I, the electronic device (105) may stop charging as well as communicating with the wearable device (103) as the electronic device (105) changes from the open state to the closed state. For example, the electronic device (105) may be in the charging stop mode when the electronic device (105) receives a signal (e.g., signal (281)) requesting to stop charging from the wearable device (103) within the open state. The signal requesting the suspension of the charging may include information indicating that the wearable device (103) is fully charged. At this time, the electronic device (105) may stop charging the wearable device (103) using the first antenna (255), perform communication with the wearable device (103) using the first antenna (255) during a first time period of the time period, and stop performing communication with the wearable device (103) using the first antenna (255) during a second time period of the time period. Thereafter, the electronic device (105) may further stop performing communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state. In other words, the electronic device (105) may change from the charging suspension mode to the sleep mode.For example, since the electronic device (105) can perform charging (or standalone charging) for the electronic device (105) using the wired interface (291), unlike case #F of FIG. 6, when the wearable device (103) is located within the electronic device (105), it can change from the charging mode to the sleep mode rather than changing from the charging mode to the power cut-off mode.

[0297] Hereinafter, for convenience of explanation, a case in which the electronic device (105) of the above example (814) operates in the charge stop mode in the open state and then changes from the charge stop mode to the sleep mode by changing to the closed state is referred to as case #M.

[0298] Referring to example (815), the electronic device (105) can be changed from the closed state to the open state. For example, when the second housing part (420) of the electronic device (105) is separated from the first housing part (410) by an external force (e.g., a change by a user), the state of the electronic device (105) (or the second housing part (420)) can be changed from the closed state to the open state. The electronic device (105) can detect the change from the closed state to the open state using the sensor (265) of the electronic device (105).

[0299] In example (815), the electronic device (105) may begin to detect that the wearable device (103) is positioned on (or in contact with, adjacent to, or connected to) the charging portion (430) of the electronic device (105) when the electronic device (105) changes from the closed state to the open state. For example, the electronic device (105) may detect whether the wearable device (103) is positioned on the charging portion (430) by periodically transmitting a signal using the first antenna (255) within the open state. In case #L or case #M of example (814), the electronic device (105) that has changed to the sleep mode may periodically transmit a signal using the first antenna (255) by changing to the ping mode. Since the wearable device (103) is positioned inside the electronic device (105) and the electronic device (105) changes to the closed state and then changes back to the open state, the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430). For example, the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430) by periodically transmitting a signal using the first antenna (255). For example, the electronic device (105) can perform charging and communication for the wearable device (103) using the first antenna (255) based on detecting that the wearable device (103) is positioned in the charging portion (430). The electronic device (105) can perform charging and communication with the wearable device (103) using the first antenna (255) by changing from the ping mode to the charging mode.

[0300] In example (815), the electronic device (105) can stop fast charging of the battery (253) of the electronic device (105) and perform fast charging of the battery (207) of the wearable device (103). In order to recycle the wearable device (103) more quickly, the electronic device (105) can stop fast charging of the battery (253) of the electronic device (105) using the wired interface (291) and perform fast charging of the battery (207) of the wearable device (103) using the wired interface (291).

[0301] Alternatively, in example (815), the electronic device (105) may determine that the wearable device (103) is positioned in the charging portion (430) of the electronic device (105) when the case (105) changes from the closed state to the open state. For example, the electronic device (105) may determine that the wearable device (103) is positioned in the charging portion (430) of the electronic device (105) using a signal (e.g., signal (281)) received while performing charging and communication with the wearable device (103) using the first antenna (255) when the case (105) changes from the closed state to the open state in the case (J) or the case (K). In example (814), the electronic device (105) in the charging mode may maintain the charging mode.

[0302] Although not shown in Example (815), the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using a light-emitting unit (not shown) of the electronic device (105) (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C). Unlike Example (615) of FIG. 6, while being charged using a wired interface (291), the electronic device (105) may maintain displaying (or continuously displaying) the battery information using the light-emitting unit.

[0303] For example, the wearable device (103) may receive battery information of the battery (253) of the electronic device (105) while performing the charging and communication with the electronic device (105). For example, the wearable device (103) may transmit (or provide) battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) to an external electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (103). Accordingly, the external electronic device may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) through a display of the external electronic device.

[0304] Referring to example (816), the electronic device (105) may begin to detect that the wearable device (103) is positioned on (or in contact with, adjacent to, or connected to) the charging portion (430) of the electronic device (105) based on detecting that the wearable device (103) is not positioned on the charging portion (430) within the open state. For example, the electronic device (105) may detect whether the wearable device (103) is positioned on the charging portion (430) by periodically transmitting a signal using the first antenna (255) within the open state. The electronic device (105) may periodically transmit a signal using the first antenna (255) by changing from the charging mode to the ping mode.

[0305] In example (816), the electronic device (105) can charge the battery (253) of the electronic device (105) based on the power provided through the wired interface (291). For example, when the wired interface (291) is used, fast charging of the battery (253) can be performed. For example, while performing the fast charging, the electronic device (105) can display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C). For example, the battery (253) can be in a charging or fully charged state.

[0306] Although not illustrated in FIG. 8B, in example (816), while detecting whether the electronic device (105) is positioned in the charging portion (430) within the open state, the electronic device (105) may detect that the state of the electronic device (105) has changed from the open state to the closed state. For example, when the electronic device (105) changes to the closed state, the electronic device (105) may refrain from (or stop, not perform) charging and communication using the first antenna (255). For example, the electronic device (105) may be in the power cutoff mode within the closed state. For example, in the electronic device (105) in the power cutoff mode, both the processor (251) and the IC (261) may be turned off.

[0307] Cases for charging operations of the electronic device (105), as described in FIG. 8b, can be referenced in the table below.

[0308]

[0309] In Table 2, the charging method may indicate a charging method of the battery (253) of the electronic device (105). For example, the wired of the charging method may indicate that power is provided from a wired interface (291) for wired charging of the battery (253) to a USB port (271). In Table 2, the cover state may indicate a state of the electronic device (105) or a state of the second housing part (420) of the electronic device (105). For example, the open state of the cover state may indicate the open state of the electronic device (105) (or the second housing part (420)), and the closed state of the cover state may indicate the closed state of the electronic device (105) (or the second housing part (420)). In Table 2, the charging status may indicate whether charging of the battery (253) of the electronic device (105) and / or charging (and communication) of the battery (207) of the wearable device (103) is performed. For example, the charging may indicate that the electronic device (105) uses the first antenna (255) to charge the battery (207) of the wearable device (103). For example, the charging stop may indicate that the electronic device (105) uses the first antenna (255) to stop charging the battery (207) of the wearable device (103). For example, the temperature at the time of the charging stop may indicate that the temperature of the wearable device (103) and / or the electronic device (105) exceeds the reference temperature. For example, when the charging is stopped, the ring being fully charged may indicate that the battery (207) of the wearable device (103) is fully charged. For example, when the charging is stopped, the case being fully charged may indicate that the battery (253) of the electronic device (105) is fully charged.In FIG. 8B, it is described that the electronic device (105) detects that the wearable device (103) is positioned in the charging portion (430) by periodically transmitting a signal within the ping mode or transmitting and receiving a signal within the charging mode or the charging stop mode, but the present disclosure is not limited thereto. For example, if the electronic device (105) includes a sensor (e.g., sensor (265) of FIG. 2) for detecting that the wearable device (103) is positioned in the charging portion (430), the electronic device (105) may also detect that the wearable device (103) is positioned in the charging portion (430) using the sensor.

[0310] FIG. 8C illustrates examples of a method for performing charging and communication for a wearable device using a first antenna when an electronic device for charging a wearable device receives power from outside the electronic device via wireless charging.

[0311] FIG. 8c illustrates examples (821, 822, 823, 824, 825, 826) of how an electronic device (105) performs charging and communication with a wearable device (103) using a first antenna (255) based on power provided via a wireless interface (293).

[0312] The electronic device (105) of FIG. 8C may be an example of the electronic device (105) of FIG. 2 and the electronic devices (105) of FIGS. 4A to 4C. The wearable device (103) of FIG. 8C may be an example of the wearable device (103) of FIG. 2 and the wearable devices (103) of FIGS. 3A and 3B. The wireless interface (293) of FIG. 8C may be an example of the wireless interface (293) of FIG. 2.

[0313] Referring to FIG. 8C, example (821) may represent a case where the electronic device (105) is in the closed state and the wearable device (103) is not positioned within the electronic device (105). Example (822) may represent a case where the electronic device (105) changes from the closed state to the open state. Example (823) may represent a case where the wearable device (103) is detected within the changed open state of the electronic device (105) (or moves from outside the electronic device (105) to the charging portion (430) of the electronic device (105). Example (824) may represent a case where the wearable device (103) is positioned within the electronic device (105) and the electronic device (105) changes from the open state to the closed state. Example (825) may represent a case where a wearable device (103) is positioned within an electronic device (105) and the electronic device (105) changes from the closed state to the open state. Example (826) may represent a case where the wearable device (103) is not detected within the changed open state of the electronic device (105) (or moves from the charging portion (430) of the electronic device (105) to the outside of the electronic device (105).

[0314] Referring to example (821), the electronic device (105) may refrain from (or stop, not perform) charging and communication using the first antenna (255) within the closed state. For example, the electronic device (105) may be in the power cutoff mode within the closed state. For example, in the electronic device (105) in the power cutoff mode, both the processor (251) and the IC (261) may be turned off. As described in example (820) of FIG. 8A, in example (821), the electronic device (105) may charge the battery (253) of the electronic device (105) based on the power provided via the wireless interface (293). For example, when the wireless interface (293) is used, normal charging of the battery (253) may be performed. For example, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C) while performing the above-described normal charging. For example, the battery (253) may be in a charging or fully charged state.

[0315] Although not shown in Example (821), the electronic device (105) may stop wireless charging when the temperature of the electronic device (105) exceeds a reference temperature while performing wireless charging using the wireless interface (293). Thereafter, the electronic device (105) may resume wireless charging when the temperature of the electronic device (105) is below the reference temperature.

[0316] Referring to example (822), the electronic device (105) can be changed from the closed state to the open state. For example, when the second housing part (420) of the electronic device (105) is separated from the first housing part (410) by an external force (e.g., a change by a user), the state of the electronic device (105) (or the second housing part (420)) can be changed from the closed state to the open state. The electronic device (105) can detect the change from the closed state to the open state using the sensor (265) of the electronic device (105). As a non-limiting example, the electronic device (105) can detect the change from the closed state to the open state by detecting a change in magnetism, a change in light quantity, a change in tension, or an input to a physical button on the electronic device (105) using the sensor (265).

[0317] In example (822), the electronic device (105) may begin to detect, within the open state, whether the wearable device (103) is positioned on (or in contact with, adjacent to, or connected to) the charging portion (430) of the electronic device (105). For example, the electronic device (105) may detect, within the open state, whether the wearable device (103) is positioned on the charging portion (430) by periodically transmitting a signal using the first antenna (255). The electronic device (105) may periodically transmit a signal using the first antenna (255) by changing from the power cut mode to the ping mode. As a non-limiting example, the signal may be transmitted at a specified period (e.g., approximately 500 ms). The signal may not include information (or data, packets).

[0318] Although not illustrated in Example (822), the electronic device (105) may display battery information of the battery (253) of the electronic device (105) using a light-emitting unit (not illustrated) (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C) when changing from the closed state to the open state. For example, the electronic device (105) may display the battery information using the light-emitting unit. Unlike Example (602) of FIG. 6, while being charged using the wireless interface (293), the electronic device (105) may maintain displaying the battery information using the light-emitting unit (or continuously display the battery information over time).

[0319] Referring to example (823), the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430) within the open state. For example, the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430) by periodically transmitting a signal using the first antenna (255). For example, the electronic device (105) can perform charging and communication for the wearable device (103) using the first antenna (255) based on detecting that the wearable device (103) is positioned in the charging portion (430). The electronic device (105) can perform charging and communication for the wearable device (103) using the first antenna (255) by changing from the ping mode to the charging mode. In example (823), the electronic device (105) can perform normal charging on the battery (207) of the wearable device (103) while simultaneously performing normal charging on the battery (253) of the electronic device (105). The electronic device (105) can perform normal charging on the battery (253) of the electronic device (105) using the wireless interface (293) while simultaneously performing normal charging on the battery (207) of the wearable device (103) using the first antenna (255) based on power provided from the battery (253) of the electronic device (105). Hereinafter, performing normal charging on the battery (253) of the electronic device (105) using the wireless interface (293) and the battery (207) of the wearable device (103) using the first antenna (255) simultaneously may be referred to as simultaneous charging.

[0320] Hereinafter, for convenience of explanation, a case in which the electronic device (105) of the above example (823) detects that the wearable device (103) is positioned in the charging portion (430) within the open state, thereby performing charging and communication with the wearable device (103) using the first antenna (255) (or changing from the ping mode to the charging mode) is referred to as case #N.

[0321] Although not shown in example (823), when the electronic device (105) detects that the wearable device (103) is positioned in the charging portion (430) within the open state, the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using a light-emitting portion (not shown) of the electronic device (105) (e.g., light-emitting portion (263) of FIG. 2 or light-emitting portion (435) of FIG. 4C). Unlike example (602) of FIG. 6, while being charged using the wireless interface (293), the electronic device (105) may maintain displaying (or continuously displaying) the battery information using the light-emitting portion.

[0322] In example (823), the wearable device (103) may receive battery information of the battery (253) of the electronic device (105) while performing the charging and communication with the electronic device (105). For example, the wearable device (103) may transmit (or provide) battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) to an external electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (103). Accordingly, the external electronic device may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) through a display of the external electronic device. Specific details related thereto are described below with reference to FIGS. 9A to 9C.

[0323] In example (823), the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103) while performing the charging and communication with the wearable device (103). For example, the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103) (e.g., signal (281) of FIG. 2). For example, the signal requesting discontinuation of charging may include information indicating that the battery (207) of the wearable device (103) is fully charged. Accordingly, the electronic device (105) may stop charging the wearable device (103) using the first antenna (255), perform communication with the wearable device (103) using the first antenna (255) during a first time period of the time period, and stop performing communication with the wearable device (103) using the first antenna (255) during a second time period of the time period. In other words, the electronic device (105) may change from the charging mode to the charging stop mode. In the above example, when the wearable device (103) identifies that the battery (207) is full, it may transmit (or provide) information indicating that the battery (207) is full to the external electronic device, and cause the external electronic device to indicate that the battery (207) of the wearable device (103) is full. Additionally, the electronic device (105) can display battery information (e.g., full charge) for the battery (207) of the wearable device (103) using the light-emitting unit (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C). While being charged using the wireless interface (293), the electronic device (105) can maintain displaying (or continuously displaying) the battery information using the light-emitting unit.

[0324] In example (823), the electronic device (105) may stop normal charging of the battery (207) of the wearable device (103) and perform normal charging of the battery (253) of the electronic device (105). For example, the electronic device (105) may perform normal charging of the battery (253) of the electronic device (105) using the wireless interface (293) as normal charging of the battery (207) of the wearable device (103) using the wireless interface (293) is stopped.

[0325] Hereinafter, for convenience of explanation, a case in which the electronic device (105) of the above example (823) receives a signal requesting discontinuation of charging from the wearable device (103) within the open state (including information indicating that the battery (207) of the wearable device (103) is fully charged), thereby discontinuing charging and periodically changing the performance and discontinuation of communication (or changing from the charging mode to the charging discontinuation mode) is referred to as case #O. In case #O, the electronic device (105) can perform normal charging of the battery (253) of the electronic device (105) using the wireless interface (293).

[0326] In the above case #O, the battery (207) of the wearable device (103) is fully charged first, and the battery (253) of the electronic device (105) is not fully charged. However, the present disclosure is not limited thereto. For example, the electronic device (105) can perform normal charging of the battery (207) of the wearable device (103) while simultaneously performing normal charging of the battery (253) of the electronic device (105) when the battery (253) of the electronic device (105) is fully charged first.

[0327] In example (823), when both the battery (207) of the wearable device (103) and the battery (253) of the electronic device (105) are fully charged, the electronic device (105) may stop the fast charging (or standalone charging) using the wireless interface (293) and maintain the charging stop mode. For example, after the electronic device (105) stops the fast charging (or standalone charging) for the electronic device (105) using the wireless interface (293), the electronic device (105) may stop charging the wearable device (103) using the first antenna (255), perform communication with the wearable device (103) using the first antenna (255) during a first time period of the time period, and stop performing communication with the wearable device (103) using the first antenna (255) during a second time period of the time period. For convenience of explanation, in the following, the electronic device (105) of the above example (823) is referred to as case #P when the battery (253) of the electronic device (105) is fully charged (or the charging interruption mode is maintained) in case #O.

[0328] Referring to example (824), the electronic device (105) can be changed from the open state to the closed state. For example, when the second housing part (420) of the electronic device (105) comes into contact with the first housing part (410) due to an external force (e.g., a change by a user), the state of the electronic device (105) (or the second housing part (420)) can be changed from the open state to the closed state. The electronic device (105) can detect the change from the open state to the closed state using the sensor (265) of the electronic device (105).

[0329] In example (824), the electronic device (105) can maintain charging (or simultaneous charging) and communication with the wearable device (103) using the first antenna (255) if the electronic device (105) changes from the open state to the closed state before receiving a signal requesting discontinuation of charging from the wearable device (103). By maintaining the charging mode, the electronic device (105) can perform charging (or simultaneous charging) and communication with the wearable device (103) using the first antenna (255). For example, the electronic device (105) can maintain charging (or simultaneous charging) and communication with the wearable device (103) using the wireless interface (293).

[0330] For example, in the case #N, the electronic device (105) can maintain charging (or simultaneous charging) and communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state. Hereinafter, for convenience of explanation, the case in which the electronic device (105) of the example (824) maintains charging (or single charging) and communication with the wearable device (103) using the first antenna (255) in the closed state (or maintains the charging mode) is referred to as case #Q.

[0331] In example (824), the electronic device (105) may determine whether the temperature of the wearable device (103) exceeds a reference temperature while performing charging (or simultaneous charging) and communication with the wearable device (103) using the first antenna (255). For example, the electronic device (105) may stop charging (or simultaneous charging) and communication with the wearable device (103) upon determining that the temperature of the wearable device (103) exceeds the reference temperature. For example, the electronic device (105) may maintain charging (or simultaneous charging) and communication with the wearable device (103) upon determining that the temperature of the wearable device (103) is below the reference temperature. For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal requesting cessation of charging transmitted when the temperature of the wearable device (103) exceeds a reference temperature. For example, the signal requesting cessation of charging may include information indicating that the temperature of the wearable device (103) exceeds the reference temperature. For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal instructing cessation of charging (including information indicating that the temperature of the wearable device (103) exceeds the reference temperature) received while performing charging (or simultaneous charging) and communication with the wearable device (103) using the first antenna (255) in the case #Q. For example, the electronic device (105) may change the mode of the electronic device (105) from the charging mode to the sleep mode. For example, the electronic device (105) may be in the sleep mode for a specified time interval (e.g., 40 seconds). For example, the electronic device (105) may stop charging (or simultaneously charging) and communicating with the wearable device (103) using the first antenna (255) during the specified time interval.For example, the electronic device (105) may change the mode of the electronic device (105) from the sleep mode back to the charging mode after the specified time interval. For example, the electronic device (105) may re-perform (or resume) charging (or simultaneous charging) and communication with the wearable device (103) using the first antenna (255) within the changed charging mode. In the above example, the length of the specified time interval may be adjusted according to the temperature of the wearable device (103). In the above example, a case of resuming once is described, but the present disclosure is not limited thereto. For example, the electronic device (105) may change from the resumed charging mode back to the sleep mode, and then change from the changed sleep mode back to the charging mode.

[0332] In one example, the electronic device (105) may include a cooling structure (e.g., a fan) to lower the temperature of the wearable device (103) below the reference temperature. For example, the electronic device (105) may drive the cooling structure based on receiving a signal requesting the cessation of charging. Alternatively, in one example, the electronic device (105) may include a structure for heat conduction (e.g., a heat pipe) or a structure penetrating between the exterior of the electronic device (105) and the interior of the electronic device (105) to lower the temperature of the wearable device (103) below the reference temperature.

[0333] For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal requesting the stop of charging (including information indicating that the temperature of the wearable device (103) exceeds the reference temperature) while charging the electronic device (105) using the wireless interface (293) and charging (or simultaneously charging) and communicating with the wearable device (103) using the first antenna (255). For convenience of explanation, the case in which the electronic device (105) of the example (824) stops charging when the temperature of the wearable device (103) exceeds the reference temperature while in the closed state (or changes from the charging mode to the sleep mode for a specified period of time and then changes back to the charging mode) is referred to as case #R.

[0334] In example (824), while performing charging (or simultaneous charging) and communication with the wearable device (103) using the first antenna (255), the electronic device (105) may receive a signal requesting discontinuation of charging from the wearable device (103). For example, the electronic device (105) may receive a signal requesting discontinuation of charging (e.g., signal (281) of FIG. 2) from the wearable device (103). For example, the signal requesting discontinuation of charging may include information indicating that the battery (207) of the wearable device (103) is fully charged. Accordingly, the electronic device (105) may stop performing charging and communication with the wearable device (103) using the first antenna (255). For example, the electronic device (105), in the case #Q, may stop charging the wearable device (103) upon receiving a signal requesting the cessation of charging (including information indicating that the battery (207) of the wearable device (103) is fully charged) while performing charging (or single charging) and communication with the wearable device (103) using the first antenna (255). In other words, the electronic device (105) may change from the charging mode to the sleep mode. For example, the electronic device (105) may stop charging the electronic device (105) and the charging (or simultaneous charging) and communication with the wearable device (103) using the wireless interface (293), and then perform charging of the electronic device (105) using the wireless interface (293). Unlike case #E of FIG. 6, when a wearable device (103) is positioned within the electronic device (105), the electronic device (105) can change from the charging mode to the sleep mode, rather than changing from the charging mode to the power cut-off mode.

[0335] In the above example, when the wearable device (103) identifies that the battery (207) is fully charged, it can transmit (or provide) information indicating that the battery (207) is fully charged to the external electronic device, and cause the external electronic device to indicate that the battery (207) of the wearable device (103) is fully charged. In addition, the electronic device (105) can display battery information (e.g., full charge) about the battery (207) of the wearable device (103) using the light-emitting unit (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C).

[0336] For example, the electronic device (105) may stop charging the wearable device (103) based on receiving a signal indicating to stop charging (including information indicating that the battery (207) of the wearable device (103) is fully charged) while performing charging and communication with the wearable device (103) using the first antenna (255). The electronic device (105) may stop charging the wearable device (103) using the first antenna (255) among charging the electronic device (105) using the wireless interface (293) and charging (or simultaneously charging) the wearable device (103) using the first antenna (255). Hereinafter, for convenience of explanation, the case in which the electronic device (105) of the above example (824) stops charging as the battery (207) of the wearable device (103) is fully charged within the closed state and continues charging the battery (253) of the electronic device (105) (or changes from the charging mode to the sleep mode) is referred to as case #S.

[0337] In examples (823) and (824), the electronic device (105) may stop performing communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state after the battery (207) of the wearable device (103) is fully charged. For example, the electronic device (105) may stop charging as well as communicating with the wearable device (103) as the electronic device (105) changes from the open state to the closed state in the case #P. For example, the electronic device (105) may be in the charging stop mode when the electronic device (105) receives a signal (e.g., signal (281) of FIG. 2) requesting a stop of charging from the wearable device (103) within the open state. The signal requesting the suspension of the charging may include information indicating that the wearable device (103) is fully charged. At this time, the electronic device (105) may stop charging the wearable device (103) using the first antenna (255), perform communication with the wearable device (103) using the first antenna (255) during a first time period of the time period, and stop performing communication with the wearable device (103) using the first antenna (255) during a second time period of the time period. Thereafter, the electronic device (105) may further stop performing communication with the wearable device (103) using the first antenna (255) when the electronic device (105) changes from the open state to the closed state. In other words, the electronic device (105) may change from the charging suspension mode to the sleep mode.For example, since the electronic device (105) can perform charging for the electronic device (105) using the wireless interface (293), unlike case #F of FIG. 6, when the wearable device (103) is located within the electronic device (105), it can change from the charging mode to the sleep mode rather than changing from the charging mode to the power cut-off mode.

[0338] Hereinafter, for convenience of explanation, a case in which the electronic device (105) of the above example (824) operates in the charge stop mode in the open state and then changes from the charge stop mode to the sleep mode by changing to the closed state is referred to as case #T.

[0339] Referring to example (825), the electronic device (105) can be changed from the closed state to the open state. For example, when the second housing part (420) of the electronic device (105) is separated from the first housing part (410) by an external force (e.g., a change by a user), the state of the electronic device (105) (or the second housing part (420)) can be changed from the closed state to the open state. The electronic device (105) can detect the change from the closed state to the open state using the sensor (265) of the electronic device (105).

[0340] In example (825), the electronic device (105) may begin to detect that the wearable device (103) is positioned (or in contact with, adjacent to, or connected to) the charging portion (430) of the electronic device (105) when the electronic device (105) changes from the closed state to the open state. For example, the electronic device (105) may detect whether the wearable device (103) is positioned at the charging portion (430) by periodically transmitting a signal using the first antenna (255) within the open state. In case #S or case #T of example (824), the electronic device (105) that has changed to the sleep mode may periodically transmit a signal using the first antenna (255) by changing to the ping mode. Since the wearable device (103) is positioned inside the electronic device (105) and the electronic device (105) changes to the closed state and then changes back to the open state, the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430). For example, the electronic device (105) can detect that the wearable device (103) is positioned in the charging portion (430) by periodically transmitting a signal using the first antenna (255). For example, the electronic device (105) can perform charging and communication for the wearable device (103) using the first antenna (255) based on detecting that the wearable device (103) is positioned in the charging portion (430). The electronic device (105) can perform charging and communication with the wearable device (103) using the first antenna (255) by changing from the ping mode to the charging mode.

[0341] In example (825), the electronic device (105) can maintain normal charging of the battery (253) of the electronic device (105) using the wireless interface (293) and can perform normal charging of the battery (207) of the wearable device (103) using the first antenna (255).

[0342] Alternatively, in example (825), the electronic device (105) may determine that the wearable device (103) is positioned in the charging portion (430) of the electronic device (105) when the case (105) changes from the closed state to the open state. For example, the electronic device (105) may determine that the wearable device (103) is positioned in the charging portion (430) of the electronic device (105) using a signal (e.g., signal (281) of FIG. 2) received while performing charging and communication with the wearable device (103) using the first antenna (255) when the case (105) changes from the closed state to the open state in the case (N) or the case (O). In example (824), the electronic device (105) in the charging mode may maintain the charging mode.

[0343] Although not shown in Example (825), the electronic device (105) may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) using a light-emitting unit (not shown) of the electronic device (105) (e.g., light-emitting unit (263) of FIG. 2 or light-emitting unit (435) of FIG. 4C). Unlike Example (615) of FIG. 6, while being charged using a wireless interface (293), the electronic device (105) may maintain displaying (or continuously displaying) the battery information using the light-emitting unit.

[0344] For example, the wearable device (103) may receive battery information of the battery (253) of the electronic device (105) while performing the charging and communication with the electronic device (105). For example, the wearable device (103) may transmit (or provide) battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) to an external electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (103). Accordingly, the external electronic device may display battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) through a display of the external electronic device.

[0345] Referring to example (826), the electronic device (105) may begin to detect that the wearable device (103) is positioned on (or in contact with, adjacent to, or connected to) the charging portion (430) of the electronic device (105) based on detecting that the wearable device (103) is not positioned on the charging portion (430) within the open state. For example, the electronic device (105) may detect whether the wearable device (103) is positioned on the charging portion (430) by periodically transmitting a signal using the first antenna (255) within the open state. The electronic device (105) may periodically transmit a signal using the first antenna (255) by changing from the charging mode to the ping mode.

[0346] In example (826), the electronic device (105) can charge the battery (253) of the electronic device (105) based on the power provided through the wireless interface (293). For example, when using the wireless interface (293), normal charging of the battery (253) can be performed. For example, while performing the normal charging, the electronic device (105) can display battery information of the battery (253) of the electronic device (105) using the light emitting unit (263) (or the light emitting unit (435) of FIG. 4C). For example, the battery (253) can be in a charging or fully charged state.

[0347] Although not illustrated in FIG. 8C, in example (826), the electronic device (105) may detect that the state of the electronic device (105) has changed from the open state to the closed state while detecting whether it is positioned in the charging portion (430) within the open state. For example, the electronic device (105) may refrain from (or stop, not perform) charging and communication using the first antenna (255) when it changes to the closed state. For example, the electronic device (105) may be in the power cutoff mode within the closed state. For example, in the electronic device (105) in the power cutoff mode, both the processor (251) and the IC (261) may be turned off.

[0348] Cases for charging operations of the electronic device (105), as described in FIG. 8c, can be referenced in the table below.

[0349]

[0350] In Table 3, the charging method may indicate a charging method of the battery (253) of the electronic device (105). For example, the wireless of the charging method may indicate a state in which power is provided from a wireless interface (293) for wireless charging of the battery (253) to the third antenna (273). In Table 3, the cover state may indicate a state of the electronic device (105) or a state of the second housing part (420) of the electronic device (105). For example, the open state of the cover state may indicate the open state of the electronic device (105) (or the second housing part (420)), and the closed state of the cover state may indicate the closed state of the electronic device (105) (or the second housing part (420)). In Table 3, the charging status may indicate whether charging of the battery (253) of the electronic device (105) and / or charging (and communication) of the battery (207) of the wearable device (103) is performed. For example, the charging may indicate that the electronic device (105) uses the first antenna (255) to charge the battery (207) of the wearable device (103). For example, the charging stop may indicate that the electronic device (105) uses the first antenna (255) to stop charging the battery (207) of the wearable device (103). For example, the temperature at the time of the charging stop may indicate that the temperature of the wearable device (103) and / or the electronic device (105) exceeds the reference temperature. For example, when the charging is stopped, the ring being fully charged may indicate that the battery (207) of the wearable device (103) is fully charged. For example, when the charging is stopped, the case being fully charged may indicate that the battery (253) of the electronic device (105) is fully charged.In FIG. 8C, it is described that the electronic device (105) detects that the wearable device (103) is positioned in the charging portion (430) by periodically transmitting a signal within the ping mode or transmitting and receiving a signal within the charging mode or the charging stop mode, but the present disclosure is not limited thereto. For example, if the electronic device (105) includes a sensor (e.g., sensor (265) of FIG. 2) for detecting that the wearable device (103) is positioned in the charging portion (430), the electronic device (105) may also detect that the wearable device (103) is positioned in the charging portion (430) using the sensor.

[0351] FIGS. 9A to 9C illustrate examples of a method for displaying battery information of a wearable device and an electronic device for charging the wearable device through a display of a source device connected to the wearable device.

[0352] FIGS. 9A to 9C illustrate examples (901, 902, 903, 904) of a method for displaying battery information of a wearable device (103) and battery information of an electronic device (105) through a display of a source device connected to the wearable device (103). For example, the source device may be an external electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (103). For example, the source device may control the wearable device (103) and, using information received from the wearable device (103), display the received information through the display. For example, the display may be an example of the display module (160) of FIG. 1.

[0353] Although not illustrated in FIGS. 9A to 9C, the electronic device (101) may receive battery information of the wearable device (103) and / or battery information of the electronic device (105) from the wearable device (103). Referring to FIGS. 5A to 5E, FIG. 6, and FIGS. 8B and 8C, the electronic device (101) may receive battery information of the battery (253) of the electronic device (105) and / or battery information of the battery (207) of the wearable device (103) from the wearable device (103). For example, the wearable device (103) may transmit battery information of the battery (207) of the wearable device (103) to the electronic device (101) when the battery of the battery (207) of the wearable device (103) changes (e.g., decreases or increases) or at a specified cycle. For example, the wearable device (103) may transmit battery information of the battery (253) of the electronic device (105) to the electronic device (101) based on identifying a specified event. As a non-limiting example, the specified event may include receiving battery information of the battery (253) included in a signal (e.g., signal (283)) from the electronic device (105) when it is detected that the wearable device (103) is positioned on the charging portion (430) of the electronic device (105), or when the state of the electronic device (105) changes from the closed state to the open state while the wearable device (103) is positioned on the charging portion (430) of the electronic device (105).

[0354] Referring to example (901) of FIG. 9A, the electronic device (101) can display battery information of the battery (253) of the electronic device (105) and battery information of the battery (207) of the wearable device (103) on the display. For example, the electronic device (101) can display a screen (905) on the display.

[0355] For example, the screen (905) may include a first user interface (UI) (910) indicating the status of the electronic device (101). For example, the first UI (910) may be referred to as a status bar. For example, the first UI (910) may display an icon (911) indicating that the wearable device (103) is charging. For example, the icon (911) may include the remaining battery amount of the wearable device (103). For example, the first UI (910) may include the icon (911), the remaining battery amount of the electronic device (101), and the current time. In addition, for example, the first UI (910) may include another icon. The other icon may include the remaining battery amount of the electronic device (105).

[0356] For example, the screen (905) may include a second UI (920). For example, the second UI (920) may include a widget for displaying information about at least one electronic device connected to the electronic device (101). For example, the at least one electronic device may include a wearable device (103). For example, the second UI (920) may include a visual object (921) including battery information of the wearable device (103). For example, the visual object (921) may include an image representing the wearable device (103), a visual indication indicating that the wearable device (103) is charging (e.g., a lightning bolt image), and text representing the remaining battery amount of the wearable device (103).

[0357] For example, the screen (905) may include a third UI (930). For example, the third UI (930) may pop up from at least a portion of the screen (905) of the electronic device (101). As a non-limiting example, the at least portion may include a lower portion of the screen (905). For example, the third UI (930) may pop up when the electronic device (101) and the wearable device (103) are paired, the wearable device (103) is worn by the user, or the wearable device (103) is positioned within the electronic device (105). For example, the third UI (930) may include a visual object (931) including battery information of the wearable device (103) and a visual object (932) including battery information of the electronic device (105). For example, the visual object (931) may include an image representing a wearable device (103), text indicating that the wearable device (103) is charging, and text indicating the remaining battery level of the wearable device (103). For example, the visual object (932) may include an image representing an electronic device (105), text indicating that the electronic device (105) is charging, and text indicating the remaining battery level of the electronic device (105).

[0358] For example, the screen (905) may include a fourth UI (940). For example, the fourth UI (940) may pop up from at least a portion of the screen (905) of the electronic device (101). As a non-limiting example, the at least portion may include a lower portion of the screen (905). For example, the fourth UI (940) may pop up when the electronic device (101) and the wearable device (103) are paired, the wearable device (103) is worn by the user, or the wearable device (103) is positioned within the electronic device (105). For example, the fourth UI (940) may include text indicating battery information of the wearable device (103) and text indicating battery information of the electronic device (105). For example, the text indicating battery information of the wearable device (103) and the text indicating battery information of the electronic device (105) may each indicate text indicating that it is charging and the remaining battery amount.

[0359] For convenience of explanation, in the example (901) of FIG. 9A, the screen (905) is illustrated as including all of the first UI (910), the second UI (920), the third UI (930), and the fourth UI (940), but the present disclosure is not limited thereto. The screen (905) may display at least one of the first UI (910), the second UI (920), the third UI (930), or the fourth UI (940).

[0360] Referring to example (902) of FIG. 9B, the electronic device (101) can display battery information of the battery (253) of the electronic device (105) and battery information of the battery (207) of the wearable device (103) on the display. For example, the electronic device (101) can display a screen (905) on the display. For example, the screen (905) can include a fifth UI (950) of a software application for managing the wearable device (103) and the electronic device (105).

[0361] For example, the fifth UI (950) may include a visual object (951) including battery information of the wearable device (103) and a visual object (952) including battery information of the electronic device (105). For example, the visual object (951) may include an image representing the wearable device (103), text indicating that the wearable device (103) is being charged, and text indicating the remaining battery amount of the wearable device (103). For example, the visual object (952) may include an image representing the electronic device (105), text indicating that the electronic device (105) is being charged, and text indicating the remaining battery amount of the electronic device (105). For example, the fifth UI (950) may further include at least one visual object (953) of a bar type for managing the wearable device (103) and the electronic device (105).

[0362] Referring to example (903) of FIG. 9c, the electronic device (101) can display battery information of the battery (253) of the electronic device (105) and battery information of the battery (207) of the wearable device (103) on the display. For example, the electronic device (101) can display a screen (905) on the display. For example, the screen (905) can include a sixth UI (960). For example, the sixth UI (960) can be displayed in response to obtaining an input (e.g., a swipe input) for the first UI (910) of FIG. 9a. For example, the sixth UI (960) can be referred to as a status display window.

[0363] For example, the sixth UI (960) may include a visual object (961) including battery information of the wearable device (103) and battery information of the electronic device (105). For example, the visual object (961) may include text indicating battery information of the wearable device (103) and text indicating battery information of the electronic device (105). For example, each of the text indicating battery information of the wearable device (103) and the text indicating battery information of the electronic device (105) may indicate text indicating that it is charging and a remaining battery amount.

[0364] Referring to example (904) of FIG. 9c, the electronic device (101) can display battery information of the battery (253) of the electronic device (105) and battery information of the battery (207) of the wearable device (103) on the display. For example, the electronic device (101) can display a screen (970) on the display. For example, the screen (970) can represent a screen (or an AOD screen) displayed in a low-power mode (or an AOD (always on display) mode) of the electronic device (101).

[0365] For example, the screen (970) may display an icon (971) indicating that the wearable device (103) is charging. The icon (971) may be referenced as a widget. For example, the icon (971) may include a visual indication indicating that the wearable device (103) is charging and a remaining battery level of the wearable device (103). Although not shown in the example (904) of FIG. 9C, the screen (970) may include another icon. The other icon may include a remaining battery level of the electronic device (105).

[0366] As described above, the electronic device (105) may include a housing including a first housing part (410) and a second housing part (420) movably coupled to the first housing part (410) between a closed state and an open state. The first housing part (410) may include an antenna (255) for providing power for charging the wearable device (103) and for communicating with the wearable device (103), and may include a charging portion (430) where the wearable device (103) is to be positioned. The first housing part (410) may include a battery (253) for storing the power. The first housing part (410) may include a memory for storing instructions and including one or more storage media. The first housing part (410) may include at least one processor (251) connected to the battery (253) and managing the power. The instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to begin detecting, using the antenna (255), that the wearable device (103) is positioned in the charging portion (430) as the second housing part (420) changes from the closed state to the open state. The instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to perform, using the antenna (255), the charging and the communication with the wearable device (103) based on detecting, within the open state of the second housing part (420), that the wearable device (103) is positioned in the charging portion (430).The above instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to receive, from the wearable device (103), a signal requesting cessation of charging while performing the charging and the communication with the wearable device (103) within the open state of the second housing part (420). The instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to, based on receiving the signal requesting discontinuation of the charging within the open state of the second housing part (420), stop performing the charging to the wearable device (103) using the antenna (255), perform the communication to the wearable device (103) using the antenna (255) during a first time period of the time period, and stop performing the communication to the wearable device (103) using the antenna (255) during a second time period of the time period.

[0367] According to one embodiment, the wearable device (103) may have a ring shape. The charging portion (430) may have a post shape into which the wearable device (103) having the ring shape can be fitted.

The at least one sensor (265) may include at least one of a Hall sensor, a light sensor, or a strain sensor.

[0369] In one embodiment, the instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to, within the open state of the second housing part (420), identify, using the at least one sensor, that the second housing part (420) has changed from the open state to the closed state before receiving the signal requesting discontinuation of the charging after detecting that the wearable device (103) is positioned in the charging portion (430).

[0370] According to one embodiment, the electronic device (105) may further include at least one other sensor (265). The instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to identify a temperature of the electronic device (105) using the at least one other sensor (265) while performing the charging and the communication with the wearable device (103) using the antenna (255) within the closed state of the second housing part (420). The instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to suspend performing the charging and the communication with the wearable device (103) using the antenna (255) for a specified time interval based on identifying the temperature exceeding a reference temperature within the closed state of the second housing part (420). The instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to resume performing the charging and the communication with the wearable device (103) using the antenna (255) after the specified time interval within the closed state of the second housing part (420).

[0371] According to one embodiment, the instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to resume performing the charging and the communication with the wearable device (103) using the antenna (255) within the closed state of the second housing part (420), and then to continue performing the charging and the communication with the wearable device (103) using the antenna (255) as the second housing part (420) changes from the closed state to the open state.

[0372] According to one embodiment, the instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to transmit version information of firmware of the electronic device (105) to the wearable device (103) while maintaining the charging and the communication with the wearable device (103) using the antenna (255) within the closed state of the second housing part (420). The instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to receive update information for the firmware of the electronic device (105) from the wearable device (103) in response to transmitting the version information of the firmware of the electronic device (105) while maintaining the charging and the communication with the wearable device (103) using the antenna (255) within the closed state of the second housing part (420). The instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to perform an update of the firmware of the electronic device (105) using the received update information while maintaining the charging and the communication with the wearable device (103) using the antenna (255) within the closed state of the second housing part (420).

[0373] According to one embodiment, the update to the firmware may be performed when the remaining battery of the battery (253) of the electronic device (105) is greater than or equal to a reference battery amount.

[0374] According to one embodiment, the instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to receive, from the wearable device (103), a signal requesting cessation of charging, the signal including information indicating that a battery of the wearable device (103) is fully charged, while performing the charging and the communication with the wearable device (103) using the antenna (255) within the closed state of the second housing part (420). The above instructions, when individually or collectively executed by the at least one processor (251), may cause the electronic device (105) to stop performing the charging and the communication with the wearable device (103) using the antenna (255) based on receiving the signal requesting the cessation of the charging within the closed state of the second housing part (420).
