Abstract

Provided is an electronic device including a secondary battery, a charging section which charges the secondary battery with power supplied from an external power supply section with a set charging current, a measurement section which measures an amount of charge accumulated in the secondary battery, a time information acquisition section which acquires time information, a storage section which stores charging history information indicating a time period in which a user performs charging, and a control section which has a chargeable time estimation section that estimates chargeable time based on the charging history information and the time information, and a charging current setting section that calculates a restricted charging current which enables the secondary battery to be charged up to a charging capacity within the chargeable time, based on the amount of charge acquired from the measurement section, and sets the restricted charging current in the charging section.
