Provided is an apparatus and method for displaying a strength of power and an expected charge completion time during wireless charging. To this end, a first electronic device, upon receiving a power request message, converts stored or wirelessly supplied power into a wirelessly-transmittable form and transmits the converted power. A second electronic device, upon receiving a charging command, determines whether being located in a distance and a position which allow charging with the first electronic device, transmits the power request message to the first electronic device, receives the converted power from the first electronic device to measure the strength of the received power, and calculates an expected charge completion time by using the detected strength of power, if the second electronic device is located in the distance and position which allow charging. |
