Abstract: An electronic device is provided. The electronic device includes a housing having a first surface and a second surface, a display exposed through the first surface of the housing, a conductive coil disposed inside the housing and forming a portion of the second surface of the housing, a movable member operatively connected to at least a portion of the housing and including one or more magnets that generate a magnetic field that passes through the conductive coil, a first charging circuit electrically connected to the conductive coil for wirelessly receiving power from an external device using the conductive coil and supplying the received power to a battery of the electronic device, and a second charging circuit electrically connected to the conductive coil for supplying, to the battery of the electronic device, power that is induced in the conductive coil based on movement of the movable member.
