Abstract
An electronic device comprises a main battery used as a drive power source for driving the electronic device, a secondary battery used as a drive power source instead of the main battery when the main battery cannot be used, a battery detection unit that detects an event of removal of the main battery from the electronic device, and a power control unit that changes the drive power source from the main battery to the secondary battery and controls operation of the electronic device to reduce power consumption by the electronic device when removal of the main battery is detected by the battery detection unit.
