Abstract

An electronic device include a housing, a touchscreen display viewable through a portion of the housing, a wireless communication circuitry disposed inside the housing, a processor disposed inside the housing and operatively connected to the touchscreen display and the wireless communication circuitry, and a memory operatively connected to the processor. The memory stores instructions that, when executed, cause the processor to receive a first signal indicating a charging state of a battery from an external electronic device including the battery through the wireless communication circuitry, and to provide a user interface corresponding to charging of the battery, based at least partially on the first signal.
