  • Patent number: 10338662
    Abstract: A low power detection apparatus and a method for displaying information are provided. When a low power manager drives a proximity detection sensor to generate a proximity interrupt in a state within which the portable terminal is in an idle state, the low power manager drives a motion detection sensor and determines a motion of the portable terminal for a preset time. When there is no motion of the portable terminal for the preset time, the low power manager generates proximity data for displaying screen information and then transmits the generated proximity data to an application processor so as to display screen information which the user desires with low power.
