Abstract
A method for wireless charging an electronic device and a method therefor are provided. The electronic device includes a near field communication device, a wireless charging device including a conductive coil, and at least one processor operatively connected to the near field communication device and the wireless charging device. The at least one processor is configured to transmit a first ping, using the near field communication device, receive first acknowledgement (ACK) information responsive to the first ping from an external electronic device, transmit a second ping, using the wireless charging device, based on that the first ACK information is received, and control the wireless charging device such that a charging current flows through the conductive coil based on second ACK information responsive to the second ping being received from the external electronic device within a specified time from the transmission of the second ping.
