An electronic device includes a charging unit that charges a battery using power from an external power source, an authentication unit that performs authentication to determine whether the battery is a predetermined battery, a detection unit that detects a voltage of the battery, and a control unit that causes the charging unit to charge the battery with a current not more than a first current value until the voltage of the battery reaches a first predetermined value and causes the authentication unit to operate on power from the battery when the voltage of the battery reaches the first predetermined value. When the voltage of the battery has reached the first predetermined value, the control unit causes the authentication unit to authenticate the battery.
