Abstract

There is a demand for an information processing device capable of maintaining, as long as possible, a state in which a decrease an the processing speed of a CPU due to heat generation hardly occurs. Therefore, proposed is an information processing device including a secondary battery, and the information processing device includes a measurement unit that measures a remaining amount of the secondary battery, a determination unit that determines whether or not the remaining amount is equal to or more than a first threshold and determines whether or not a specific application is in a foreground state, and a charge control unit that stops charging the secondary battery by using an external power supply in a case where the remaining amount is equal to or more than the first threshold and the specific application is in the foreground state.
