Kind Code:
A1
Abstract:
Various embodiments of the present invention relate to an electronic device and a method for quickly executing a wireless power sharing function. The electronic device may comprise a coil, a sensor, a communication circuit, a wireless power transmission circuit electrically connected to the coil, and a processor, wherein the processor: determines, by using the sensor, whether the electronic device is placed to face a designated direction; if the electronic device is placed to face the designated direction, senses proximity of an external device by using the communication circuit; if proximity of the external device is sensed, transmits a designated ping by using the wireless power transmission circuit; receives a feedback signal for the designated ping from the external device; and transmits power to the external device through the coil in response to the feedback signal. The present invention may further include various other embodiments.
