Abstract

An electronic apparatus includes a charging unit configured to charge a battery, and a control unit. The control unit is configured to control the charging unit to charge the battery based on a first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is not less than a predetermined threshold. The control unit is configured to control the charging unit to charge the battery based on a second charging condition in which a full charge capacity of the battery is greater than in the first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is less than the predetermined threshold.

Claims (13)

1. An electronic apparatus comprising:

a charging unit configured to charge a battery; and

a control unit configured to (a) control the charging unit to charge the battery based on a first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is not less than a predetermined threshold, and (b) control the charging unit to charge the battery based on a second charging condition in which a full charge capacity of the battery is greater than in the first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is less than the predetermined threshold.

2. The electronic apparatus according to claim 1 , wherein the control unit is configured to calculate an operable time of the electronic apparatus based on a voltage of the battery and an operating time of the electronic apparatus.

3. The electronic apparatus according to claim 1 , wherein the first charging condition includes a value that designates at least one of a charging voltage, a charge termination current, and a charging time that are to be used when charging of the battery is controlled.

4. A method comprising:

causing a charging unit of an electronic apparatus to charge a battery;

controlling the charging unit to charge the battery based on a first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is not less than a predetermined threshold; and

controlling the charging unit to charge the battery based on a second charging condition in which a full charge capacity of the battery is greater than in the first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is less than the predetermined threshold.

5. A non-transitory storage medium storing a program for causing a computer to execute a method, the method comprising:

causing a charging unit of an electronic apparatus to charge a battery;

controlling the charging unit to charge the battery based on a first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is not less than a predetermined threshold; and

controlling the charging unit to charge the battery based on a second charging condition in which a full charge capacity of the battery is greater than in the first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is less than the predetermined threshold.
