An electronic device includes a battery, a charging integrated circuit (IC) configured to control a charging state of the battery, a connector pin for receiving power from an external device, the connector pin including a first connector pin for receiving a high potential voltage from the external device and a second connector pin for receiving a low potential voltage from the external device, a touch sensor, and a controller. The controller receives power from the external device through the connector pin based on the detection of the external device being connected to the connector pin, charges the battery using a high potential voltage, detects a user input through the touch sensor while the battery is charged, and stops the charging of the battery and outputs a current corresponding to state information of the electronic device through the first connector pin based on the detection of the given user input.

Electronic device and method for communicating with external device through power source line

An electronic device according to various embodiments includes a housing including an acoustic channel and a nozzle portion having an opening formed therein for connecting the acoustic channel to an outside of the electronic device, and an eartip detachably engaged with the housing through at least a portion of the nozzle portion. The eartip includes a first area, at least a portion of which is formed of an elastic material and comes into contact with an object, and a second area, at least a portion of which is formed of an elastic material and surrounds at least a portion of the nozzle portion. The second area includes a first portion having a hole having a first size and a second portion having a second size larger than the first size, and a protrusion is formed at an end of the second portion in a first direction.

Eartip including foreign matter inflow prevention portion and electronic device including the same

An electronic device according to various embodiments of the present disclosure may include a communication interface and a processor, wherein the processor may be configured to receive first battery level information of a first earpiece and second battery level information of a second earpiece, via the communication interface, to identify a charging method corresponding to the first battery level and the second battery level, among a plurality of charging methods for charging at least one of the first earpiece or the second earpiece, and to control to supply charging power to at least one of the first earpiece or the second earpiece, via a cable which connects the electronic device with at least one of the first earpiece or the second earpiece, using the charging method.
