把你的手机到睡眠模式，延长电池寿命。
The purpose of this app is to put your phone to a sleep mode and save battery life.
To uninstall the app go to Settings-Security-Device Administrators and uncheck the check box next to the app name.
It is used to put the phone to sleep mode, instead of pressing physical power key.It won't drain your battery and it won't leave any threads nor hold any wake locks. There is no any ads.
With a new case for my phone it was very hard to press the power button. So I created this app.
