Abstract: 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.

Abstract: Provided in various embodiments is a method for operating an electronic device. The method may comprise the operations of: recognizing, through a communication circuit of the electronic device, that an external device connected to a connector of the electronic device is a power supply device having the function of changing a voltage value and a current value; selecting, on the basis of the recognition, a direct charging circuit from among the direct charging circuit and a switching charging circuit of the electronic device as a charging circuit through which a power signal, received from the power supply device through the power source terminal, is to pass; and confirming the voltage of the battery on the basis of the occurrence of a designated event while the direct charging circuit is selected, and requesting, through the communication circuit, the power supply device to output a power signal having a voltage value that is N times the battery voltage. Other various embodiments are possible.

Abstract: 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.
