ABSTRACT:
A power saving method for a mobile telephone is disclosed that can increase the useful life of a battery charge by temporarily turning off non-essential telephone functions not required for call transmission or reception. The method determines whether the remaining capacity of the telephone battery is smaller than a predetermined reference value. The power saving method includes the steps of setting an activation condition for non-essential telephone functions, detecting a state that satisfies the activation condition, measuring the remaining capacity of the telephone's battery if the activation condition is satisfied, and controlling an activation operation of the non-essential telephone functions by comparing the measured remaining charged capacity with a reference value. The power saving method may include saving to and recalling from memory user preference settings when a user function is de-activated and re-activated, respectively.
