Abstract:
1. An electronic device comprising: a power receiving coil configured to receive an electric power from a charger by electromagnetic induction; a secondary battery configured to be charged with the received electric power; an antenna configured to conduct a proximity noncontact communication with the charger; and a charging and communication controlling section configured to control the charging of the secondary battery and the proximity noncontact communication, wherein, if a voltage of the secondary battery is below a first value, the charging and communication controlling section controls a first charging of the secondary battery with the electric power received via the power receiving coil until the voltage of the secondary battery becomes the first value or more; wherein the proximity noncontact communication is conducted after the first charging is conducted; and wherein a second charging of the secondary battery is conducted until the voltage of the secondary battery becomes a second value larger than the first value after the proximity noncontact communication is conducted.
