[0149] In one embodiment, the second battery (425) may be charged with power received through the third coil (424). In one embodiment, the second battery (425) may supply power to each component included in the second body (420).

[0150] According to one embodiment, the charging operation of the first battery (418) and the operation of charging the second battery (425) with the power of the first battery (418) will be described in more detail below with reference to FIG. 8.

[0151] According to one embodiment, when the remaining amount of the first battery (418) is less than a set value (e.g., 10%), the processor (419) may transmit a power transfer command to the second body (420) through the first communication module (415) and the second communication module (423). According to one embodiment, the MCU (426) may transfer power of the second battery (425) to the first battery (418) through the third coil (424) and the second coil (417) based on the received power transfer command. According to one embodiment, when the power transfer command is received, the MCU (426) may transfer power of the second battery (425) to the first battery (418) only when the remaining amount of the second battery (425) is equal to or greater than the set value (e.g., 10%).

[0152] In one embodiment, although the electronic device is described above as including both the first body (410) and the second body (420), the electronic device may also include only the first body (410). In one embodiment, when the electronic device includes only the first body (410), the second body (420) may be an external electronic device.

[0153] In one embodiment, when the electronic device includes only the first body (410), the electronic device can perform the same operation as the operation of the first body (410).

[0154] FIG. 5 is a flowchart for explaining an operation based on the attachment state of the first housing and the second housing of an electronic device according to one embodiment of the present disclosure.

[0155] Referring to FIG. 5, in operation 510, an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (101) of FIG. 2A, the electronic device (101) of FIG. 2B, the processor (120) of FIG. 1, or the processor (419) of FIG. 4) can detect the intensity (e.g., change) of a magnetic field through a Hall sensor (e.g., the sensor module (176) of FIG. 1 or the Hall sensor (413) of FIG. 4).

[0156] According to one embodiment, the electronic device can detect a change in a magnetic field through a Hall sensor when a first magnet (e.g., a first magnet (311) of FIG. 3A) of a first housing (e.g., a first housing (310) of FIG. 3A) and a third magnet (e.g., a third magnet (321) of FIG. 3A) of a second housing (e.g., a second housing (320) of FIG. 3A)) are attached, or when a second magnet (e.g., a second magnet (312) of FIG. 3A) of the first housing and a fourth magnet (e.g., a fourth magnet (322) of FIG. 3A) of the second housing are attached.

[0157] According to one embodiment, in operation 520, the electronic device can determine, based on the amount of change in the detected magnetic field, whether the attachment state of the first housing and the second housing is a first state attached by the first magnet and the third magnet or a second state attached by the second magnet and the fourth magnet.

[0158] According to one embodiment, when the first magnet of the first housing and the third magnet of the second housing are attached, the magnitude of the change in the magnetic field detected by the Hall sensor is different from the magnitude of the change in the magnetic field detected by the Hall sensor when the second magnet of the first housing and the fourth magnet of the second housing are attached. Therefore, when the first housing and the second housing are attached, the electronic device can determine whether the attachment state of the first housing and the second housing is the first state or the second state based on the magnitude of the change in the magnetic field sensed through the Hall sensor.

[0159] According to one embodiment, the first state may be a state in which a wider side among the sides adjacent to a first side of a first housing on which a first display (e.g., the display module (160) of FIG. 1, the first display (211) of FIG. 2A, the first display (211) of FIG. 2B, the first display (211) of FIG. 3A, or the first display (411) of FIG. 4)) is disposed is attached to a wider side among the sides adjacent to a first side of a second housing on which a second display (e.g., the display module (160) of FIG. 1, the second display (221) of FIG. 2A, the second display (221) of FIG. 2B, the second display (221) of FIG. 3A, or the second display (421) of FIG. 4)) is disposed. According to one embodiment, in the first state, a long edge of the first display and a long edge of the second display are disposed parallel to each other, and a single screen can be displayed through the first display and the second display.

[0160] According to one embodiment, the second state may be a state in which a narrow side among the sides adjacent to the first side of the first housing on which the first display is arranged is attached to a narrow side among the sides adjacent to the first side of the second housing on which the second display is arranged.

[0161] According to one embodiment, in operation 530, the electronic device can determine the screens to be displayed on the first display and the second display based on the confirmed attachment state.

[0162] In one embodiment, the difference between the horizontal and vertical lengths of the screen in the first state may be less than a set value. In one embodiment, the difference between the horizontal and vertical lengths of the screen in the second state may be a narrow and long shape that is greater than or equal to the set value.

[0163] According to one embodiment, the electronic device can display screens of different shapes (e.g., a wide rectangle or a narrow and long rectangle) depending on the arrangement of the first display and the second display.

[0164] In one embodiment, in operation 540, the electronic device can display a first area corresponding to a first display on the screen on the first display.

[0165] In one embodiment, in operation 550, the electronic device may transmit a second area corresponding to a second display, which is continuous with a first area of ​​the screen, to the second communication module through the first communication module so that it is displayed on the second display.

[0166] In one embodiment, although FIG. 5 illustrates that operations 540 and 550 are performed sequentially, this is not limited, and at least a portion of operation 540 and at least a portion of operation 550 may be performed simultaneously.

[0167] According to one embodiment, the electronic device can display one screen through the first display and the second display.

[0168] According to one embodiment, when the attachment state of the first housing and the second housing is changed, the electronic device can change the screen based on the arrangement of the first display and the second display that is changed according to the change in the attachment state.

[0169] According to one embodiment, an example of a screen displayed in the first state will be described with reference to FIG. 11 below, and an example of a screen displayed in the second state will be described with reference to FIG. 12 below.

[0170] In one embodiment, the electronic device can charge the first battery based on power received from an external charging device via the first coil.

[0171] According to one embodiment, in the first state, based on the first battery being fully charged, power from the first battery can be transferred to the third coil via the second coil. According to one embodiment, the second battery can be charged with the power received via the third coil. According to one embodiment, the first battery charging and second battery charging operations are described in more detail below with reference to FIG. 8.

[0172] According to one embodiment, in a first state and in a state where power is not received from an external charging device, based on the remaining amount of the first battery being less than a set value, the electronic device can transmit a power transfer command to the second communication module through the first communication module.

[0173] According to one embodiment, an MCU (e.g., MCU (426) of FIG. 4) disposed in the second housing may transmit power from the second battery to the second coil through the third coil based on receiving a power transfer command through the second communication module. According to one embodiment, the first battery may be charged with the power received through the second coil. According to one embodiment, an operation of charging the first battery with power from the second battery will be described in more detail below with reference to FIG. 9.

[0174] According to one embodiment, the MCU may transmit the sensing value acquired through the second sensor to the first communication module through the second communication module. According to one embodiment, the electronic device may store the sensing value received through the first communication module and the sensing value acquired through the first sensor in memory.

[0175] According to one embodiment, the first sensor and the second sensor may be 6-axis sensors. According to one embodiment, in the first state, the electronic device may turn off the second sensor. According to one embodiment, in the second state, based on the sensing value of the first sensor, it may be determined whether the electronic device is in sleep mode. According to one embodiment, if the sensing value of the first sensor is less than a set value, the electronic device may determine that the electronic device is in sleep mode. According to one embodiment, if the sensing value of the first sensor is greater than or equal to a set value, the electronic device may determine that the electronic device is in sports mode.

[0176] In one embodiment, the electronic device may turn off the second sensor based on determining that the electronic device is in sleep mode. In one embodiment, the electronic device may turn on the second sensor based on determining that the electronic device is not in sleep mode.

[0177] According to one embodiment, in a third state where the first housing and the second housing are not attached, both the 6-axis sensor disposed in the first housing and the 6-axis sensor disposed in the second housing may be turned on. According to one embodiment, based on the change in the attachment state of the first housing and the second housing from the third state to the second state, if the sensing value of the 6-axis sensor of the second housing is equal to or greater than a set value, the 6-axis sensor of the second housing may be kept on, and if it is equal to or less than the set value, the 6-axis sensor of the second housing may be turned off.

[0178] In one embodiment, the sensor may include a light emitter and a light receiver. In one embodiment, the light emitter of the sensor may be disposed in a first housing, and the light receiver of the sensor may be disposed in a second housing.

[0179] According to one embodiment, the electronic device can emit light for sensing through a light emitter. According to one embodiment, the electronic device can receive light emitted from the light emitter through a light receiving unit.

[0180] According to one embodiment, the MCU may transmit the sensing value acquired through the light receiving unit to the first communication module through the second communication module. According to one embodiment, the electronic device may store the sensing value received through the first communication module in memory.

[0181] According to one embodiment, the arrangement and operation of multiple sensors will be described in more detail with reference to FIGS. 6 and 7 below.

[0182] According to one embodiment, the electronic device can determine that the attachment state is a third state in which the first housing and the second housing are separated based on the fact that no change in the magnetic field is detected through the Hall sensor. According to one embodiment, the MCU can transmit the sensing value acquired through the second sensor to the first communication module through the second communication module even in the state in which the first housing and the second housing are separated. According to one embodiment, the sensing value received through the first communication module and the sensing value acquired through the first sensor can be stored in the memory.

[0183] In one embodiment, the first sensor and the second sensor may be six-axis sensors.

[0184] According to one embodiment, the electronic device may determine that the electronic device is in sports mode based on a value sensed by the first sensor and a value sensed by the second sensor in the third state.

[0185] For example, if the first housing is worn on the user's left wrist and the second housing is worn on the user's right wrist, the MCU can transmit the sensing value acquired through the second sensor to the first communication module through the second communication module even when the first housing and the second housing are separated.

[0186] In this way, when the first housing and the second housing are worn on each of the user's wrists, the user's movements can be sensed more accurately than when the first housing and the second housing are worn on one of the user's wrists.

[0187] According to one embodiment, the electronic device may acquire a first screen to be displayed on the first display and a second screen to be displayed on the second display based on the electronic device being in sports mode. According to one embodiment, the first screen and the second screen may not be continuous. For example, the first screen and the second screen may be separate screens rather than portions of a single screen. According to one embodiment, the first screen and the second screen may be the same screen or different screens.

[0188] In one embodiment, the electronic device may display a first screen on a first display. In one embodiment, the electronic device may transmit a second screen to a second communication module via the first communication module so that the second screen is displayed on the second display.

[0189] In one embodiment, although the electronic device is described above as including both the first housing and the second housing, the electronic device may include only the first housing and the components disposed in the first housing, and the second housing and the components disposed in the second housing may be external electronic devices.

[0190] In one embodiment, when the electronic device includes only a first housing and components disposed in the first housing, the electronic device can only perform the operations of the processor.

[0191] According to one embodiment, the electronic device can detect a magnetic field through a Hall sensor. According to one embodiment, the electronic device can determine, based on the strength of the detected magnetic field, whether the attachment state of the electronic device and the external electronic device is a first state in which the electronic device is attached by a first magnet or a second state in which the electronic device is attached by a second magnet. According to one embodiment, the electronic device can determine a screen to be displayed on the first display and the display of the external electronic device based on the determined attachment state.

[0192] In one embodiment, the electronic device may display a first area of ​​the screen corresponding to the display on the display. In one embodiment, the second area of ​​the screen corresponding to the display of the external electronic device may be transmitted to the external electronic device via the communication module so that the second area is displayed on the display of the external electronic device.

[0193] In this way, the electronic device can provide different form factors depending on the attachment status of the first housing and the second housing. In one embodiment, the electronic device can display a screen corresponding to the display arrangement that varies depending on the attachment status of the first housing and the second housing.

[0194] FIG. 6 is a drawing for explaining the sensor arrangement when the attachment state of the first housing and the second housing of the electronic device according to one embodiment of the present disclosure is the second state.
