Abstract:
A method and electronic device for performing wireless charging are provided. The electronic device includes a housing, a conductive coil, a power transmission circuit electrically connected to the conductive coil, and configured to wirelessly transmit power to an outside of the housing through the conductive coil, a voltage source electrically connected to the power transmission circuit, and a control circuit electrically connected between the power transmission circuit and the voltage source. The control circuit is configured to change power radiated through the conductive coil, monitor a frequency of a signal and/or electromagnetic waves radiated through the conductive coil, and adjust a level of a voltage from the voltage source based on at least a part of a monitored result of the frequency.
