    Abstract: An electronic includes: a housing including a first plate, a second plate, and a side member; a display; a conductive coil parallel to the second plate and disposed between the display and the second plate; a wireless charging circuitry electrically connected to the conductive coil; and a processor operatively connected with the display and the wireless charging circuitry. The wireless charging circuitry receives a signal for wirelessly transferring power to an external electronic device from the processor, receives information about the external electronic device, receives a power control signal from the external electronic device via the conductive coil, applies a charging current of a first frequency to the conductive coil based at least in part on a request signal, increases a frequency of the charging current, compares the increased frequency with a first value, and adjusts a duty cycle of the charging current.

    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.
