PROBLEM TO BE SOLVED: To provide a technology for reducing capacity deterioration of a battery to be mounted on a portable electronic apparatus.SOLUTION: An electronic apparatus 10 comprises a plurality of batteries (a first battery and a second battery) and a charge/discharge control part. The electronic apparatus 10 displays an icon 52 on a display 142 and visually displays the residual capacity of the plurality of batteries mounted on the electronic apparatus 10. The electronic apparatus 10 sets any one of the first and second batteries as a primary battery, sets the other battery as a secondary battery and controls charge of the battery to be the primary battery and the battery to be the secondary battery every time the batteries are charged. The electronic apparatus 10 fully charges the primary battery and charges the secondary battery to a voltage that is less than full charge. The electronic apparatus 10 preferentially discharges the battery defined as the primary battery when the batteries are discharged. The electronic apparatus 10 changes setting of the battery defined as the primary battery when controlling the charge of the plurality of batteries.SELECTED DRAWING: Figure 2 |
