Abstract
An electronic device includes a wireless charging coil, a wireless charging circuit, a power management module, a battery, and a processor. The processor is configured to control to receive first information from an external electronic device while transmitting wireless charging power to the external electronic device through the wireless charging circuit, to control, in response to receiving the first information, the wireless charging circuit to stop transmission of the wireless charging power and operate in a state of transmitting and receiving a ping signal, to check whether a predetermined time has elapsed since the transmission of the wireless charging power is stopped, and to control, in response to elapse of the predetermined time, the wireless charging circuit to retransmit the wireless charging power to the external electronic device. Other embodiments are possible.
