Abstract: A wireless power receiving device includes a first housing, a second housing coupled to the first housing to be changed in relative position with respect to the first housing, a first resonance circuit disposed in the first housing, and at least one processor. The at least one processor may be configured to control the wireless power receiving device to wirelessly receive power from a wireless power transmitting device through the first resonance circuit, identify a charging efficiency corresponding to the received wireless power, and in case the identified charging efficiency is less than a threshold, provide content for changing an angle between the first housing and the second housing.
