An apparatus and method for controlling a battery power source of an electronic device by resetting battery information stored in a memory. In addition, the battery is discharged until a battery voltage reaches a prescribed discharge end voltage, even when the power source supply to the device is switched from the battery to another source. The battery information includes a realizable capacity and a residual capacity of the battery. The realizable capacity is a parameter used for indicating a battery performance and the residual capacity is used for calculating a usable residual time of the device.
