FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication equipment which employs electronic devices with batteries, and is intended to slow down battery ageing caused by charging current and repeated charge-discharge cycles with virtually maximum charge capacity. The invention discloses an electronic device which includes a battery, a charging section which charges the battery with energy obtained from an external power source determined by charging current, a measuring section which measures the value of charge accumulated in the battery, a temporary information collection section which collects temporary information, a storage section which stores charging history showing the period of time during which the user performs charging, and a control section which includes a section for estimating chargeable time based on charging history and temporary information, and a section for setting charging current which calculates a limited charging current which enables to charge the battery to a given charge capacity over the chargeable time based on data on the amount of charge obtained from the measuring section and which sets the limited charging current in the charging section.
EFFECT: slower battery ageing.
