摘要： An electronic device may include a display, a power reception circuit, and a processor. The processor may perform wireless charging by receiving power wirelessly from an external electronic device through the power reception circuit, and receive data on one or more reasons to stop wireless charging from the external electronic device during the wireless charging. Also, the processor may transmit acknowledge (ACK) data to the external electronic device in response to receiving the data on the one or more reasons to stop wireless charging, and display, through the display, at least one reason to stop wireless charging included in the data on the one or more reasons to stop wireless charging. Other embodiments are possible.

摘要： An electronic device is provided. The electronic device includes a housing, a power interface exposed through at least a portion of the housing to be connected to an external power source in a wired manner or disposed inside the housing to be connected to the external power source in a wireless manner, at least one battery disposed inside the housing and electrically connected to the power interface, a processor disposed inside the housing and operatively connected to the power interface, and a memory disposed inside the housing and operatively connected to the processor. The memory stores instructions that, when executed, causes the processor to, in a state in which an external power is supplied through the power interface, when a voltage of the battery reaches a first voltage value, lower the voltage of the battery to a second voltage value lower than the first voltage value by discharging the battery after a first time has elapsed from a time point at which the voltage of the battery reaches the first voltage value.
