Power-saving processing method of mobile terminal and power-saving processing system of mobile terminal

The invention relates to a power-saving processing method of a mobile terminal. The method comprises the following steps: setting a monitoring time length T of an application program; counting an idletime t of each application program from an operation instruction received when the user operates the application program as a timing starting point, wherein the idle time t refers to a time that theapplication program does not receive an operation instruction issued by the user after being started; judging the relationship between t and T, and if t < T, returning to the previous step; if t=T, the application is closed. 本发明涉及种移动终端的省电处理方法，所述方法包括以下步骤：设定应用程序的监控时间长度T；从接收用户操作所述应用程序时的操作指令作为计时起点，统计每个所述应用程序的闲置时间t，所述闲置时间t是指所述应用程序在开启后未接收到用户发出的操作指令所持续的时间；判断t与T之间的关系，若t＜T，则返回上步；若t＝T，则关闭所述应用程序。
