Abstract
The invention provides a low-electric-quantity shutdown method. The shutdown operation is carried out according to using states of an electronic device. The using states of the electronic device include a high-power-consumption using state and a low power-consumption using state. The low-electric-quantity shutdown method comprises the following steps of detecting whether battery electric quantity is lower than a preset charging threshold value or not; judging whether the electronic device is in the high-power-consumption using state or not when the battery electric quantity is lower than the preset charging threshold value; and delaying shutdown when the electronic device is in the high-power-consumption using state. When the current electric quantity of a battery is lower than the preset charging threshold value and the electronic device is in the high-power-consumption using state, the shutdown is delayed, accordingly long stand-by time of the battery can be kept, and the service life of the battery can be prolonged.
