PROBLEM TO BE SOLVED: To provide a mobile electric apparatus which saves current for use when its battery cannot be continuously used until arrival time at a chargeable location.;SOLUTION: A controller 3 receives setting of scheduled arrival time at a chargeable location, and a timer 7 calculates a time: T [h] until a built-in battery can be charged. If T is equal to or less than zero, a battery remaining detector 5 detects the remaining amount of the battery: V [mA h] under current using condition. In addition, a current-for-use detector 6 detects a current for use: I (mA) under current using condition. Then, if T is equal to or greater than V/I, the controller 3 decreases the brightness of an LCD display backlight 11. Hereinafter, the above processing is repeated.;COPYRIGHT: (C)2011,JPO&INPIT
