Abstract: [Object] To achieve both prevention of overcharging of the battery and convenience of the user.
[Solution] An information processing device includes: a charged capacity detection unit configured to detect a charged capacity of a battery; a charging control unit configured to control a charging circuit; and a specification unit configured to specify when discharge of the battery starts. The charging control unit performs charging suppression control on the charging circuit such that the battery is charged to a preparatorily charged capacity that is lower than a fully charged capacity of the battery, on the basis of the charged capacity detected by the charged capacity detection unit, the charging of the battery stops when the charged capacity of the battery reaches the preparatorily charged capacity, and the charging of the battery restarts from the preparatorily charged capacity before discharge of the battery starts.
