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.
