Abstract
An electronic device includes a coil, and at least one control circuit electrically connected to the coil. The control circuit is configured to transmit power to an external device via the coil by using a first frequency belonging to a first frequency band, receive a packet related with wireless charging from the external device via the coil, in response to having failed to receive the packet within a first reference time, change at least one of an amplitude of the power transmitted or the first frequency used for the transmitting of the power, and to transmit power to the external device via the coil on the basis of the at least one of the changed transmit power or the changed frequency.
