A battery capacity measurer(24) measures a battery capacity of a mobile communication terminal. A user input unit(14) designates a kind of power-saving mode, and sets a power-saving mode battery entering capacity and power-saving mode items corresponding to the designated kind of the power-saving mode. A memory(20) stores the set power-saving mode entering battery capacity and the power-saving mode items. A controller(10) performs a power-saving control function corresponding to the set items if the measured battery capacity reaches the set power-saving mode battery capacity.
