An electronic device which is wirelessly charged through an external power transmitting device includes a conductive pattern in which a current is induced depending on a power signal transmitted by the external power transmitting device, an adjustment circuit that configured to generate a voltage signal using the current, a load configured to be charged through the voltage signal, and a control circuit electrically connected with the conductive pattern, the adjustment circuit, and the load. Upon recognizing the external power transmitting device, the control circuit is configured to generate a power control signal including information about intensity of the power signal and to transmit the power control signal to the external power transmitting device through the conductive pattern, and the conductive pattern is configured to receive the power signal, the intensity of which is changed depending on the power control signal.
