An information processing apparatus has a battery portion which supplies power, a remaining capacity detecting portion which detects a remaining capacity of the battery portion, a remaining time computing portion which computes a remaining time during which processing of an application for information processing can be carried out by the power supplied from the battery portion, on the basis of the remaining capacity detected by the remaining capacity detecting portion, and a display portion which displays the remaining time computed by the remaining time computing portion. In this manner, a user can know a time of an application which can be used with a current remaining battery capacity from a screen.
