Abstract:
An electronic device according to an embodiment may include: a wireless charging coil; a power transmission circuit configured to be electrically connected to the wireless charging coil; a wireless communication circuit configured to communicate with an external electronic device; and a control circuit. The control circuit may be configured to: transmit power to an external electronic device; obtain data corresponding to power received by the external electronic device in response to the transmitted power using the wireless communication circuit; obtain power loss based on the obtained data; stop transmitting the power to the external electronic device when the power loss exceeds a first threshold; and stop transmitting the power to the external electronic device according to whether an event related the power loss occurs even when the power loss is lower than the first threshold.
