Power saving control method and device

The embodiment of the invention discloses a power saving control method which is used for lowering the electric quantity consumption of a mobile terminal. The method comprises the steps that a screen off instruction is received; a screen is closed according to the screen off instruction, and the screen is in a blank screen state; whether first duration of the blank screen state is larger than a first preset threshold value or not is detected, and the first duration is obtained by taking a time point of the detected blank screen state as a starting point; if the first duration is larger than the first preset threshold value, first background application of the mobile terminal is frozen. The embodiment of the invention further provides a power saving control device so as to save the electricity quantity of the mobile terminal and prolong the duration of the mobile terminal. 本发明实施例公开了种省电控制方法，用于降低移动终端的电量消耗。本发明实施例方法包括：接收熄屏指令；根据熄屏指令关闭屏幕，使得屏幕进入黑屏状态；检测黑屏状态的第持续时长是否大于第预设阈值，第持续时长为移动终端以检测到黑屏状态的时刻点为起点计算得到；若第持续时长大于第预设阈值，则冻
