[0061] Referring to FIG. 5, in operation 501, according to one embodiment, an electronic device (100; 210; 220) may display first battery information of a charging case (130) based on a first request provided from a charging case (130). The operation of displaying first battery information of a charging case (130) may include an operation of controlling a light-emitting element (108; 218; 228) to display first information corresponding to the first battery information of a charging case (130). The first battery information of a charging case (130) may include information regarding the charging state of a battery (137) of a charging case (130). For example, the first battery information of a charging case (130) (e.g., information regarding the charging state) may include sub-information indicating that the battery (137) of a charging case (130) is charging. For example, the first battery information of the charging case (130) (e.g., information about the charging status) may include sub-information indicating that the charging of the battery (137) of the charging case (130) is completed. For example, the first battery information of the charging case (130) (e.g., information about the charging status) may include sub-information regarding the amount of charge (e.g., charge level or charge ratio) of the battery (137) of the charging case (130). "Sub-information" may be an expression indicating information included in the battery information.

[0062] An example of operation of 501 can be described as follows. According to one embodiment, an electronic device (100; 210; 220) can check first battery information of the charging case (130) provided from the charging case (130) based on electrical communication through a connector (101; 211; 221) while the electronic device (100; 210; 220) is seated in the charging case (130). For example, the first wearable device (210) can check the first battery information of the charging case (130) provided from the charging case (130) based on electrical communication through the connector (211) while the first wearable device (210) is placed in the charging case (130) (e.g., information on the charging status of the battery (137) of the charging case (130)). For example, the second wearable device (220) can check the first battery information of the charging case (130) provided from the charging case (130) based on electrical communication through the connector (221) while the second wearable device (220) is placed in the charging case (130). According to one embodiment, the electronic device (100; 210; 220) may receive a first request provided from the charging case (130) based on a first input identified in the charging case (130). The charging case (130) may identify a first input (e.g., a first user input) that is input through an input means (e.g., a button (136) of FIG. 3, a sensor (420), a microphone (430), or other input means). The charging case (130) may provide a first request to the electronic device (100; 210; 220) based on the first input (e.g., a first user input). The first request may be a request for display of battery information (e.g., first battery information of the charging case (130) (e.g., information about the charge status of the battery (137) of the charging case (130)).For example, the first wearable device (210) may receive a first request provided from the charging case (130) based on a first input identified in the charging case (130). The charging case (130) may provide the first request to the first wearable device (210) based on the first input (e.g., first user input). For example, the second wearable device (220) may receive a first request provided from the charging case (130) based on a first input identified in the charging case (130). The charging case (130) may provide the first request to the second wearable device (220) based on the first input (e.g., first user input). According to one embodiment, the first input of the 501 operation and the second input of the 503 operation described below may be inputs through a microphone of the electronic device (100; 210; 220). For example, the electronic device (100; 210; 220) may detect, through the microphone of the electronic device (100; 210; 220), an input that causes the display of battery information of the charging case (130) (e.g., the first input of the aforementioned 501 operation) or an input that causes the display of battery information of the electronic device (100; 210; 220) (e.g., the second input of the 503 operation described below). According to one embodiment, the first battery information of the charging case (130) (e.g., information regarding the charge status of the battery (137) of the charging case (130)), and the first request for the display of battery information (e.g., information regarding the charge status of the first battery information of the charging case (130) (e.g., information regarding the charge status of the battery (137) of the charging case (130)) may be provided together or sequentially. If the information and the request are provided sequentially, there is no restriction on the order of provision. According to one embodiment, the electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to display first information corresponding to first battery information of the charging case (130) based on a first request provided from the charging case (130).For example, the first wearable device (210) may control the light-emitting element (218) to display first information corresponding to first battery information of the charging case (130) based on a first request provided from the charging case (130). For example, the second wearable device (220) may control the light-emitting element (228) to display first information corresponding to first battery information of the charging case (130) based on a first request provided from the charging case (130). Specific operations for controlling the light-emitting elements (108; 218; 228) can be explained with reference to the embodiments of FIGS. 6 to 12 and the embodiments described below. According to one embodiment, one of the first wearable device (210) and the second wearable device (220) (e.g., the first wearable device (210)) displays battery information of the charging case (130) (e.g., the first battery information), and the other of the first wearable device (210) and the second wearable device (220) (e.g., the second wearable device (220)) may display battery information of the electronic device (100; 210; 220) (e.g., the second battery information described below). For example, the first wearable device (210) may control the light-emitting element (218) to display first information corresponding to first battery information of the charging case (130) based on a first request provided from the charging case (130), and the second wearable device (220) may control the light-emitting element (228) to display second information corresponding to second battery information of the electronic device (100; 210; 220) based on a second request provided from the charging case (130) (e.g., second request of the 503 operation described below). For example, the first wearable device (210) may display second information corresponding to second battery information of the electronic device (100; 210; 220), and the second wearable device (220) may display first information corresponding to first battery information of the charging case (130).According to one embodiment, one of the first wearable device (210) and the second wearable device (220) (e.g., the first wearable device (210)) displays battery information (e.g., first battery information) of the charging case (130) based on a first request provided from the charging case (130), and the other of the first wearable device (210) and the second wearable device (220) (e.g., the second wearable device (220)) may ignore the first request provided from the charging case (130). According to one embodiment, the electronic device (100; 210; 220) may receive first battery information of the charging case (130) (e.g., information on the charge status of the battery (137) of the charging case (130)) from the charging case (130) at a designated time while the electronic device (100; 210; 220) is seated in the charging case (130). For example, the charging case (130) may provide the first battery information of the charging case (130) (e.g., information on the charge status of the battery (137) of the charging case (130)) to the electronic device (100; 210; 220) at a designated time. According to one embodiment, an electronic device (100; 210; 220) may receive first battery information of the charging case (130) (e.g., information on the charging status of the battery (137) of the charging case (130)) from the charging case (130) based on confirmation of a designated event (e.g., start of charging of the charging case (130), completion of charging, or change of charging level) while the electronic device (100; 210; 220) is seated in the charging case (130). For example, the charging case (130) may provide first battery information of the charging case (130) (e.g., information on the charging status of the battery (137) of the charging case (130)) to the electronic device (100; 210; 220) based on confirmation of a designated event (e.g., start of charging of the charging case (130), completion of charging, or change of charging level).According to one embodiment, the electronic device (100; 210; 220) may store first battery information of the received charging case (130) (e.g., information about the charge state of the battery (137) of the charging case (130)) in a memory (105; 215; 225). According to one embodiment, the electronic device (100; 210; 220) may check the first battery information of the charging case (130) stored in the memory (105; 215; 225) based on a first request provided from the charging case (130), and control a light-emitting element (218) to display first information corresponding to the checked first battery information.

[0063] In operation 503, according to one embodiment, the electronic device (100; 210; 220) may display second battery information of the electronic device (100; 210; 220) based on a second request provided from a charging case (130). The operation of displaying second battery information of the electronic device (100; 210; 220) may include an operation of controlling a light-emitting element (108; 218; 228) to display second information corresponding to the second battery information of the electronic device (100; 210; 220). The second battery information of the electronic device (100; 210; 220) may include information regarding the charge state of the battery (102; 212; 222) of the electronic device (100; 210; 220). For example, the second battery information (e.g., information about the charging state) of the electronic device (100; 210; 220) may include sub-information indicating that the battery (102; 212; 222) of the electronic device (100; 210; 220) is charging. For example, the second battery information (e.g., information about the charging state) of the electronic device (100; 210; 220) may include sub-information indicating that the charging of the battery (102; 212; 222) of the electronic device (100; 210; 220) is complete. For example, the second battery information (e.g., information about the charge state) of the electronic device (100; 210; 220) may include sub-information about the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220). “Sub-information” may be an expression indicating information included in the battery information.

[0064] 503 An example of operation can be described as follows. According to one embodiment, an electronic device (100; 210; 220) can check second battery information of the electronic device (100; 210; 220) (e.g., information about the charge state of the battery (102; 212; 222)). For example, a first wearable device (210) can check battery information of the first wearable device (210) (e.g., information about the charge state of the battery (212)). For example, a second wearable device (220) can check battery information of the second wearable device (220) (e.g., information about the charge state of the battery (222)). According to one embodiment, the electronic device (100; 210; 220) may receive a second request provided from the charging case (130) based on a second input identified in the charging case (130). The charging case (130) may identify a second input (e.g., a second user input) that is input through an input means (e.g., a button (136) of FIG. 3, a sensor (420), a microphone (430), or other input means). The charging case (130) may provide a second request to the electronic device (100; 210; 220) based on the second input (e.g., the second user input). The second request may be a request for display of battery information (e.g., information about the charge status of the battery (102; 212; 222) of the electronic device (100; 210; 220)). For example, the first wearable device (210) may receive a second request provided from the charging case (130) based on a second input identified in the charging case (130). The charging case (130) may provide the second request to the first wearable device (210) based on the second input (e.g., a second user input). For example, the second wearable device (220) may receive a second request provided from the charging case (130) based on a second input identified in the charging case (130).The charging case (130) may provide a second request to the second wearable device (220) based on a second input (e.g., a second user input). According to one embodiment, the electronic device (100; 210; 220) may control a light-emitting element (108; 218; 228) to display second information corresponding to second battery information of the electronic device (100; 210; 220) based on a second request provided from the charging case (130). For example, the first wearable device (210) may control a light-emitting element (218) to display second information corresponding to battery information of the first wearable device (210) based on a second request provided from the charging case (130). For example, the second wearable device (220) may control the light-emitting element (228) to display second information corresponding to battery information of the second wearable device (220) based on a second request provided from the charging case (130). Specific operations for controlling the light-emitting element (108; 218; 228) can be explained with reference to the embodiments of FIGS. 6 to 12 and the embodiments described below.

[0065] Examples of the first and second requests of FIG. 5 can be described as follows. According to one embodiment, the first input may include an input corresponding to the action of pressing the button (136) of the charging case (130) once. The first request may correspond to the first input. The second input may include an input corresponding to the action of pressing the button (136) of the charging case (130) twice. The second request may correspond to the second input. According to one embodiment, the first input may include an input corresponding to the action of pressing the button (136) of the charging case (130) twice. The first request may correspond to the first input. The second input may include an input corresponding to the action of pressing the button (136) of the charging case (130) once. The second request may correspond to the second input. According to one embodiment, the first input may include an input corresponding to an action of pressing the button (136) of the charging case (130) for less than a reference time. The first request may correspond to the first input. The second input may include an input corresponding to an action of pressing the button (136) of the charging case (130) for more than a reference time. The second request may correspond to the second input. According to one embodiment, the first input may include an input corresponding to an action of pressing the button (136) of the charging case (130) for more than a reference time. The first request may correspond to the first input. The second input may include an input corresponding to an action of pressing the button (136) of the charging case (130) for less than a reference time. The second request may correspond to the second input. According to one embodiment, the first input and the second input may be inputs of the same type. For example, the second input may include an input that is verified within a set period after the first input has been verified. The first request (e.g., a request corresponding to the first input) and the second request (e.g., a request corresponding to the second input) may be requests of the same type.For example, the second request may include a request that is confirmed within a set period after the first request has been confirmed. For example, if the first input and the second input are of the same type of input, the battery information of the charging case (130) and the battery information of the electronic device (100; 210; 220) may be displayed alternately based on the repetition of the input (e.g., user input for the charging case (130)). This will be explained in detail in FIG. 23. The descriptions of the first input and the second input are exemplary, and the descriptions of the first input and the second input of the 501 operation and the 503 operation may be applied in reverse. For example, the battery information of the electronic device (100; 210; 220) may be displayed based on the first request based on the first input, and the battery information of the charging case (130) may be displayed based on the second request based on the second input.

[0066] Specific operations for controlling light-emitting elements (108; 218; 228) will be explained with reference to the embodiments of FIGS. 6 to 12.

[0067] Referring to FIG. 6, according to one embodiment, an electronic device (100; 210; 220) can determine the color of a light-emitting element (108; 218; 228) based on a request provided from a charging case (130).

[0068] For example, in FIG. 6, the electronic device (100; 210; 220) may display first battery information of the charging case (130) (e.g., information on the charge status of the battery (137) of the charging case (130)) based on a first request provided from the charging case (130), and may display second battery information of the electronic device (100; 210; 220) (e.g., information on the charge status of the battery (102; 212; 222) of the electronic device (100; 210; 220) based on a second request provided from the charging case (130). According to one embodiment, only one of the first wearable device (210) and the second wearable device (220) may display the first battery information of the charging case (130) (e.g., information on the charge status of the battery (137) of the charging case (130). According to one embodiment, the second battery information of the electronic device (100; 210; 220) displayed on the first wearable device (210) (e.g., information about the charge state of the battery (102; 212; 222) of the electronic device (100; 210; 220)) may be battery information of the battery (212) of the first wearable device (210). According to one embodiment, the second battery information of the electronic device (100; 210; 220) displayed on the first wearable device (210) (e.g., information on the charge state of the battery (102; 212; 222) of the electronic device (100; 210; 220)) may be the average value of the charge amount of the battery (212) of the first wearable device (210) and the charge amount of the battery (222) of the second wearable device (220). According to one embodiment, the second battery information of the electronic device (100; 210; 220) displayed on the second wearable device (220) (e.g., information about the charge status of the battery (102; 212; 222) of the electronic device (100; 210; 220)) may be battery information of the battery (222) of the second wearable device (220).According to one embodiment, the second battery information of the electronic device (100; 210; 220) displayed on the second wearable device (220) (e.g., information on the charge state of the battery (102; 212; 222) of the electronic device (100; 210; 220)) may be the average value of the charge amount of the battery (212) of the first wearable device (210) and the charge amount of the battery (222) of the second wearable device (220).

[0069] For example, in FIG. 6(a), while the electronic device (100; 210; 220) is seated in the charging case (130), the light-emitting element (108; 218; 228) of the electronic device (100; 210; 220) can be controlled to off while no input (e.g., user input) is detected through the button (136) of the charging case (130). Subsequently, while the electronic device (100; 210; 220) is seated in the charging case (130), a first input (e.g., first user input (610)) can be detected through the button (136) of the charging case (130). The electronic device (100; 210; 220) can receive a first request corresponding to the first input (e.g., first user input) from the charging case (130).

[0070] For example, in FIG. 6(b), based on a first request corresponding to a first input (e.g., a first user input), the electronic device (100; 210; 220) may control a light-emitting element (108; 218; 228) to display first information (e.g., information about color) corresponding to first battery information of the charging case (130) (e.g., information about the charging state of the battery (137) of the charging case (130)). For example, the electronic device (100; 210; 220) may control a light-emitting element (108; 218; 228) to display a first color (e.g., red) corresponding to sub-information indicating that the charging case (130) is charging. For example, the electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to display a second color (e.g., green) corresponding to sub-information indicating that the charging of the charging case (130) is complete. Subsequently, with the electronic device (100; 210; 220) seated in the charging case (130), a second input (e.g., a second user input (620)) can be detected through a button (136) of the charging case (130). The electronic device (100; 210; 220) can receive a second request corresponding to the second input (e.g., a second user input) from the charging case (130).

[0071] For example, in FIG. 6(c), based on a second request corresponding to a second input (e.g., a second user input (620)), the electronic device (100; 210; 220) may control a light-emitting element (108; 218; 228) to display second information (e.g., information about color) corresponding to second battery information of the electronic device (100; 210; 220) (e.g., information about the charge state of the battery (102; 212; 222) of the electronic device (100; 210; 220). For example, the electronic device (100; 210; 220) may control a light-emitting element (108; 218; 228) to display a third color (e.g., red or yellow) corresponding to sub-information indicating that the electronic device (100; 210; 220) is charging. For example, the electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to display a fourth color (e.g., green or blue) corresponding to sub-information indicating that the charging of the electronic device (100; 210; 220) is complete.

[0072] For example, in FIG. 6 (b) and (c), the first color (e.g., red) corresponding to sub-information indicating that the charging case (130) is charging and the third color (e.g., red or yellow) corresponding to sub-information indicating that the electronic device (100; 210; 220) is charging may be different. The first color (e.g., red) corresponding to sub-information indicating that the charging case (130) is charging and the third color (e.g., red or yellow) corresponding to sub-information indicating that the electronic device (100; 210; 220) is charging may be the same. The second color (e.g., green) corresponding to sub-information indicating that the charging of the charging case (130) is complete and the fourth color (e.g., green or blue) corresponding to sub-information indicating that the charging of the electronic device (100; 210; 220) is complete may be different. A second color (e.g., green) corresponding to sub-information indicating that charging of the charging case (130) is complete and a fourth color (e.g., green or blue) corresponding to sub-information indicating that charging of the electronic device (100; 210; 220) is complete may be the same. For example, the color corresponding to the information may be determined based on information regarding display settings. For example, the electronic device (100; 210; 220) may determine the color corresponding to the information based on information regarding display settings. For example, information regarding display settings may include information regarding the matching relationship of the color corresponding to the information. For example, the electronic device (100; 210; 220) may store information regarding display settings. For example, the electronic device (100; 210; 220) may receive information regarding display settings through a communication connection with an external device (e.g., 1330 in FIG. 13) (e.g., a smartphone). For example, the electronic device (100; 210; 220) can determine a color corresponding to the information based on information about a display setting (stored or received).

[0073] In the description of FIG. 6, it was explained that first battery information of the charging case (130) (e.g., information regarding the charge state of the battery (137) of the charging case (130)) is displayed based on a first request, and second battery information of the electronic device (100; 210; 220) (e.g., information regarding the charge state of the battery (102; 212; 222) of the electronic device (100; 210; 220)) is displayed based on a second request, but this is merely an example, and the electronic device (100; 210; 220) may display second battery information of the electronic device (100; 210; 220) (e.g., information regarding the charge state of the battery (102; 212; 222) of the electronic device (100; 210; 220) based on a first request, and the first battery information of the charging case (130) (e.g., Information regarding the charge status of the battery (137) of the charging case (130) can be displayed. For example, based on a first request or a second request, which information (e.g., information about the charging case (130) or information about the electronic device (100; 210; 220)) to display can be determined based on information regarding display settings. For example, the electronic device (100; 210; 220) can determine information corresponding to the request based on information regarding display settings. For example, information regarding display settings may include information regarding the matching relationship of information to be displayed in response to the request. For example, the electronic device (100; 210; 220) may store information regarding display settings. For example, the electronic device (100; 210; 220) may receive information regarding display settings through a communication connection with an external device (e.g., 1330 in FIG. 13) (e.g., a smartphone).For example, the electronic device (100; 210; 220) may, based on information regarding display settings, identify first battery information (e.g., information regarding the charge status of the battery (137) of the charging case (130)) as information to be displayed in response to a first request, and identify second battery information (e.g., information regarding the charge status of the battery (102; 212; 222) of the electronic device (100; 210; 220)) as information to be displayed in response to a second request. For example, the electronic device (100; 210; 220) may identify, based on information regarding display settings, second battery information (e.g., information regarding the charge status of the battery (102; 212; 222) of the electronic device (100; 210; 220) as information to be displayed in response to the first request, and first battery information (e.g., information regarding the charge status of the battery (137) of the charging case (130)) as information to be displayed in response to the second request.

[0074] Referring to FIG. 7, according to one embodiment, a display of battery information (e.g., information about the charge state) of a first wearable device (210) and a display of battery information (e.g., information about the charge state) of a second wearable device (220) can be described.

[0075] FIG. 7 may illustrate an operation in which an electronic device (100; 210; 220) displays battery information (e.g., information about the charge status) of the electronic device (100; 210; 220). For example, FIG. 7 may illustrate an operation in which an electronic device (100; 210; 220) displays battery information of the electronic device (100; 210; 220) based on a request from a charging case (130). In this case, the first wearable device (210) may display battery information of the first wearable device (210), and the second wearable device (220) may display battery information of the second wearable device (220). The operation of FIG. 7 may be an example of a specific operation of the aforementioned embodiments (e.g., embodiments of FIG. 5 and 6). For example, the first wearable device (210) and the second wearable device (220) may display battery information based on an input (e.g., user input in FIGS. 5 and 6) or an event (e.g., start of charging, completion of charging, or change of battery level of the electronic device (100; 210; 220). For example, the first wearable device (210) and the second wearable device (220) may display battery information for a specified time (e.g., 3 seconds) based on an input (e.g., user input in FIGS. 5 and 6) or an event (e.g., start of charging, completion of charging, or change of battery level of the electronic device (100; 210; 220). For example, the first wearable device (210) and the second wearable device (220) may continue to display battery information based on input (e.g., user input in FIG. 5 and FIG. 6) or events (e.g., start of charging, completion of charging, or change of battery level of the electronic device (100; 210; 220).

[0076] For example, in FIG. 7(a), the first wearable device (210) can receive charging power from the charging case (130) while seated in the charging case (130). Accordingly, the first wearable device (210) can control the light-emitting element (218) to display a first color (e.g., red) corresponding to sub-information indicating that the first wearable device (210) is charging. Likewise, the second wearable device (220) can receive charging power from the charging case (130) while seated in the charging case (130). Accordingly, the second wearable device (220) can control the light-emitting element (228) to display a first color (e.g., red) corresponding to sub-information indicating that the second wearable device (220) is charging.

[0077] For example, in FIG. 7(b), the first wearable device (210) can continue to receive charging power from the charging case (130) while seated in the charging case (130). Accordingly, the first wearable device (210) can control the light-emitting element (218) to display a first color (e.g., red) corresponding to sub-information indicating that the first wearable device (210) is charging. Meanwhile, the second wearable device (220) can be fully charged while seated in the charging case (130). Accordingly, the second wearable device (220) can control the light-emitting element (228) to display a second color (e.g., green) corresponding to sub-information indicating that the second wearable device (220) is fully charged.

[0078] For example, in FIG. 7(c), the first wearable device (210) can be fully charged while seated in the charging case (130). Accordingly, the first wearable device (210) can control the light-emitting element (218) to display a second color (e.g., green) corresponding to sub-information indicating that the first wearable device (210) is fully charged. The second wearable device (220) can control the light-emitting element (228) to display a second color (e.g., green) corresponding to sub-information indicating that the second wearable device (220) is fully charged, based on the completion of charging.

[0079] In FIG. 7, the first color (e.g., red) corresponding to sub-information indicating that the first wearable device (210) is charging and the second wearable device (220) may have the same first color (e.g., red) corresponding to sub-information indicating that the second wearable device (220) is charging. The first color corresponding to sub-information indicating that the first wearable device (210) is charging and the second wearable device (220) may have different first colors corresponding to sub-information indicating that the second wearable device (220) is charging. The second color (e.g., green) corresponding to sub-information indicating that the first wearable device (210) is fully charged and the second color (e.g., green) corresponding to sub-information indicating that the second wearable device (220) is fully charged may have the same first color. The second color (e.g., green) corresponding to sub-information indicating that the first wearable device (210) is fully charged and the second color (e.g., green) corresponding to sub-information indicating that the second wearable device (220) is fully charged may be different. As described above, the color corresponding to the information may be determined based on information regarding the display settings.

[0080] Referring to FIG. 8, according to one embodiment, an electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) with a brightness corresponding to a charge amount (e.g., charge level or charge ratio).

[0081] FIG. 8 may illustrate an operation in which an electronic device (100; 210; 220) displays battery information (e.g., information about the charge state) of the electronic device (100; 210; 220) or battery information (e.g., information about the charge state) of a charging case (130). For example, FIG. 8 may illustrate an operation in which an electronic device (100; 210; 220) displays battery information of the electronic device (100; 210; 220) or battery information of the charging case (130) based on a request from the charging case (130). Below, with reference to FIG. 8, an operation in which battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the electronic device (100; 210; 220) is described as an example, but with reference to this description, an operation in which battery information of the charging case (130) is also understood. Likewise, the operation of displaying battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the electronic device (100; 210; 220) is described as an example, but by referring to this description, the operation of displaying battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the first wearable device (210) and the operation of displaying battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the second wearable device (220) can be understood, respectively.

[0082] For example, in FIG. 8, the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) with a brightness corresponding to the charge amount (e.g., charge level or charge ratio) based on the battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the electronic device (100; 210; 220). For example, in FIG. 8 (a), the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) with a brightness corresponding to the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) based on a request from the charging case (130). For example, the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to a brightness corresponding to 20% (e.g., a low brightness corresponding to 20%) based on the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to a brightness corresponding to the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) based on a request from the charging case (130). For example, the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to a brightness corresponding to 50% (e.g., an intermediate brightness corresponding to 50%) based on the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) being 50%.For example, the electronic device (100; 210; 220) can control the brightness of the light-emitting element (108; 218; 228) to indicate the current charge amount (e.g., charge level or charge rate) based on the increase in the charge amount (e.g., charge level or charge rate) of the battery (102; 212; 222) as it receives charging power from the charging case (130) while seated in the charging case (130). In FIG. 8 (c), the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to a brightness corresponding to the charge amount (e.g., charge level or charge rate) of the battery (102; 212; 222) of the electronic device (100; 210; 220) based on a request from the charging case (130). For example, the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to a brightness corresponding to 80% (e.g., high brightness corresponding to 80%) based on the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) being 80%. The user can see that as the brightness of the light-emitting element (108; 218; 228) increases, the charge amount (e.g., charge level or charge ratio) increases.

[0083] Referring to FIG. 9, according to one embodiment, an electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to display information through a region corresponding to a charge amount (e.g., charge level or charge ratio) among a plurality of regions of the light-emitting element (108; 218; 228).

[0084] FIG. 9 may illustrate an operation in which an electronic device (100; 210; 220) displays battery information (e.g., information about the charge state) of the electronic device (100; 210; 220) or battery information (e.g., information about the charge state) of a charging case (130). For example, FIG. 9 may illustrate an operation in which an electronic device (100; 210; 220) displays battery information of the electronic device (100; 210; 220) or battery information of the charging case (130) based on a request from the charging case (130). Below, with reference to FIG. 9, an operation in which battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the electronic device (100; 210; 220) is described as an example, but with reference to this description, an operation in which battery information of the charging case (130) is also understood. Likewise, the operation of displaying battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the electronic device (100; 210; 220) is described as an example, but by referring to this description, the operation of displaying battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the first wearable device (210) and the operation of displaying battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the second wearable device (220) can be understood, respectively.

[0085] For example, in FIG. 9, the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to display information through an area corresponding to the charge amount (e.g., charge level or charge ratio) among a plurality of areas of the light-emitting element (108; 218; 228) based on battery information (e.g., charge amount (e.g., charge level or charge ratio)) of the electronic device (100; 218; 220). For example, as in FIG. 9, the height of the area where the light-emitting element (108; 218; 228) is controlled to be on may vary depending on the charge amount (e.g., charge level or charge ratio). For example, in FIG. 9 (a), the electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to display information through a first area corresponding to the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) based on a request from the charging case (130). For example, the electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to display information through a first area corresponding to 20% (e.g., a narrow area corresponding to 20%) based on the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) being 20%. In FIG. 9(b), the electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to display information through a second area corresponding to the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) based on a request from the charging case (130).For example, the electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to display information through a second area corresponding to 50% (e.g., an area of ​​intermediate width corresponding to 50%) based on the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) being 50%. For example, the electronic device (100; 210; 220) can control an area where a light-emitting element (108; 218; 228) is turned on to indicate the current charge amount (e.g., charge level or charge rate) based on the increase in the charge amount (e.g., charge level or charge rate) of the battery (102; 212; 222) as it receives charging power from the charging case (130) while seated in the charging case (130). In FIG. 9 (c), the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to display information through a third area corresponding to the charge amount (e.g., charge level or charge rate) of the battery (102; 212; 222) of the electronic device (100; 210; 220) based on a request from the charging case (130). For example, the electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to display information through a third area corresponding to 80% (e.g., a wide area corresponding to 80%) based on the charge amount (e.g., charge level or charge ratio) of the battery (102; 212; 222) of the electronic device (100; 210; 220) being 80%. The user can see that as the charge amount (e.g., charge level or charge ratio) increases, the height of the area where the light-emitting element (108; 218; 228) is controlled to be on increases.

[0086] According to one embodiment, FIG. 10 may show that, according to the embodiment of FIG. 9, the height of the region in which the light-emitting element (108; 218; 228) is controlled to be on increases based on the charge amount of the battery (102; 212; 222) of the electronic device (100; 210; 220), and according to the embodiment of FIG. 7, the color of the light-emitting element (108; 218; 228) changes (e.g., changes from red to green) based on the completion of charging of the electronic device (100; 210; 220).

[0087] According to one embodiment, according to the embodiment of FIG. 8, the brightness of the light-emitting element (108; 218; 228) is increased based on the charge amount of the battery (102; 212; 222) of the electronic device (100; 210; 220), and according to the embodiment of FIG. 7, the color of the light-emitting element (108; 218; 228) may be changed (e.g., changed from red to green) based on the completion of charging of the electronic device (100; 210; 220).

[0088] Referring to FIG. 11, according to one embodiment, an electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to indicate that the charge amount (e.g., the charge amount of the electronic device (100; 210; 220) or the charge amount of the charging case (130)) is 0% (or less than a reference value).

[0089] For example, in FIG. 11 (a), the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to turn off based on a request from the charging case (130) to indicate that the charge amount (e.g., the charge amount of the battery (102; 212; 222) of the electronic device (100; 210; 220) or the charge amount of the battery (137) of the charging case (130)) is 0% (or less than a reference value).

[0090] For example, in FIG. 11 (b), the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to blink based on a request from the charging case (130) to indicate that the charge amount (e.g., the charge amount of the battery (102; 212; 222) of the electronic device (100; 210; 220) or the charge amount of the battery (137) of the charging case (130)) is 0% (or less than a reference value). For example, one of the first wearable device (210) or the second wearable device (210) (e.g., the device with the higher battery charge among the first wearable device (210) or the second wearable device (210)) can control the light-emitting element (108; 218; 228) to blink based on a request from the charging case (130) to indicate that the charge amount (e.g., the charge amount of the battery (102; 212; 222) of the electronic device (100; 210; 220) or the charge amount of the battery (137) of the charging case (130)) is 0% (or a state less than a reference value).

[0091] Referring to FIG. 12, according to one embodiment, an electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to blink at a first speed to indicate that it is charging. According to one embodiment, an electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to blink at a second speed to indicate that charging is complete. For example, in FIG. 12 (a), the electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to blink at a first speed to indicate that the charging case (130) is charging, based on a first request for first battery information of the charging case (130). For example, in FIG. 12 (b), the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to blink at a second speed to indicate that the charging case (130) is fully charged, based on a first request for first battery information of the charging case (130). For example, in FIG. 12 (a), the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to blink at a first speed to indicate that the electronic device (100; 210; 220) is charging, based on a second request for second battery information of the electronic device (100; 210; 220). For example, in FIG. 12(b), the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to blink at a second speed to indicate that the electronic device (100; 210; 220) is fully charged, based on a second request for second battery information of the electronic device (100; 210; 220). According to one embodiment, the first speed of the light-emitting element (108; 218; 228) indicating that it is charging can be determined based on the battery information.For example, the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) to flash at a speed corresponding to the charge amount (e.g., the charge amount of the battery (102; 212; 222) of the electronic device (100; 210; 220) or the charge amount of the battery (137) of the charging case (130) to indicate that it is being charged. For example, the electronic device (100; 210; 220) can control the light-emitting element (108; 218; 228) so that the blinking speed is gradually increased from 0 to the detected speed, in order to check the speed corresponding to the charge amount (e.g., the charge amount of the battery (102; 212; 222) of the electronic device (100; 210; 220) or the charge amount of the battery (137) of the charging case (130)) and to indicate that it is charging, so that the operation of the blinking speed is repeated. There is no limitation on the method of controlling the blinking speed of the light-emitting element (108; 218; 228).

[0092] According to one embodiment, the electronic device (100; 210; 220) may determine the area, color, brightness, and / or blinking (e.g., whether to blink or blinking speed) of the light-emitting element (108; 218; 228) based on information regarding display settings. The electronic device (100; 210; 220) may simultaneously apply two or more of the operations controlling the area, color, brightness, and / or blinking (e.g., whether to blink or blinking speed) of the light-emitting element (108; 218; 228).

[0127] For example, information regarding display settings may be set based on user input of an external device (1330). For example, information regarding display settings may be set through an update of an application of the external device (1330). For example, information regarding display settings may include information regarding timer settings.

[0128] Referring to FIG. 20, according to one embodiment, an external device (1330) may display a screen (2010, 2020) for determining information regarding a display setting. For example, the information regarding the display setting may include information regarding a timer setting. 2010 and 2020 of FIG. 20 may display a screen set to "control the light-emitting element (108; 218; 228) to ON after 15 minutes and 30 seconds." According to one embodiment, based on information regarding a display setting (e.g., information regarding a timer setting) by 2010 and 2020 of FIG. 20, the electronic device (100; 210; 220) in FIG. 21 controls the light-emitting element (108; 218; 228) to be off before the time corresponding to the timer setting arrives (e.g., FIG. 21 (a)), and then controls the light-emitting element (108; 218; 228) to be on to display set information (e.g., first battery information of the charging case (130) or second battery information of the electronic device (100; 210; 220)) based on the arrival of the time corresponding to the timer setting (e.g., FIG. 21 (b)).

[0130] Referring to FIG. 22, according to one embodiment, a charging case (130) can determine the direction and / or distance in which an external device (1330) is placed. For example, the communication circuit (141) of the charging case (130) may include a communication circuit that supports UWB (ultra-wideband). The charging case (130) can transmit information about the direction and / or distance in which the external device (1330) is placed to an electronic device (100; 210; 220). The electronic device (100; 210; 220) can receive information about the direction and / or distance in which the external device (1330) is placed from the charging case (130). The electronic device (100; 210; 220) can control a light-emitting element (108; 218; 228) to indicate information about the direction and / or distance in which an external device (1330) is placed from a charging case (130). For example, information about the direction may be indicated by an operation in which the light-emitting element (218) of the first wearable device (210) is blinked or the light-emitting element (228) of the second wearable device (220) is blinked. For example, information about the distance may be indicated by an operation in which the brightness, color, and area in which the light-emitting element (108; 218; 228) of the electronic device (100; 210; 220) is controlled to be on are controlled. For example, in FIG. 22 (a), the electronic device (100; 210; 220) can control the light-emitting elements (108; 218; 228) such that the first element (218) among the light-emitting elements (108; 218; 228) is switched on and the area of ​​the light-emitting elements (108; 218; 228) corresponding to 10[m] is controlled to be on, so as to indicate information about the direction (e.g., left) and / or distance (e.g., 10[m]) in which the external device (1330) is placed.For example, in FIG. 22 (b), the electronic device (100; 210; 220) can control the light-emitting elements (108; 218; 228) so that the second element (228) among the light-emitting elements (108; 218; 228) is switched on and the area of ​​the light-emitting elements (108; 218; 228) corresponding to 6[m] is controlled to be on, so as to indicate information about the direction (e.g., right) and / or distance (e.g., 6[m]) in which the external device (1330) is placed. For example, in (c) of FIG. 22, the electronic device (100; 210; 220) can control the light-emitting elements (108; 218; 228) such that the second element (228) among the light-emitting elements (108; 218; 228) is switched on and the area of ​​the light-emitting elements (108; 218; 228) corresponding to 2[m] is controlled to be on, so as to indicate information about the direction (e.g., right) and / or distance (e.g., 2[m]) in which the external device (1330) is placed.

[0131] FIG. 23 is a drawing describing a request received within a set period according to one embodiment.

[0132] As described above, the charging case (130) can check input (e.g., user input). At this time, a first input corresponding to a first request and a second input corresponding to a second request will be described. For example, the first input may include an input corresponding to the action of pressing the button (136) of the charging case (130) once, and the second input may include an input corresponding to the action of pressing the button (136) of the charging case (130) twice.

Thus, the first input and the second input may be different types of inputs, but this is merely an example, and the first input and the second input may be the same type of input. Referring to FIG. 23, an embodiment in which the first input and the second input are of the same type of input can be described.

[0133] According to one embodiment, a first input that causes the display of first battery information of a charging case (130) (e.g., information about the charge state of a battery (137) of a charging case (130)) and a second input that causes the display of second battery information of an electronic device (100; 210; 220) (e.g., information about the charge state of a battery (102; 212; 222) of an electronic device (100; 210; 220)) may be of the same type of input. For example, both the first input and the second input may be inputs corresponding to the action of pressing a button (136) of a charging case (130) once, wherein the second input may include an input that is confirmed within a set period after the first input has been confirmed. For example, based on a single press of a button (136) of a charging case (130), a light-emitting element (108; 218; 228) of an electronic device (100; 210; 220) may be controlled to display first battery information of the charging case (130) (e.g., information about the charge state of the battery (137) of the charging case (130), and subsequently, based on a single press of a button (136) of the charging case (130) within a set period, a light-emitting element (108; 218; 228) of an electronic device (100; 210; 220) may be controlled to display second battery information of the electronic device (100; 210; 220) (e.g., information about the charge state of the battery (102; 212; 222) of the electronic device (100; 210; 220).
