A mobile terminal includes: a battery supplying electric power; a voltage detection portion which detects the voltage of the battery; a function activation control portion which activates a predetermined function at a preset time; and a warning portion which, in reference to a predicted battery voltage at the preset time calculated by subtracting a predicted value of reduced voltage based on a consumed current until the preset time from a detected voltage detected by the voltage detection portion, raises a waning if the predicted battery voltage is smaller than the minimum voltage that is necessary for activating the predetermined function by the function activation control portion.
