/!\ Need root device /!\
How it’s work:
It save battery by blocking CPU to it minimum value when we don’tneed it (when the screen is OFF)\n
You don’t need power when your screen is OFF, and your CPU isstill using at maximum frequency by program (in background) so thiswill lock to very low frequency your CPU and permit you to keepbattery.
Up to 3 days autonomy !!!
You can see on one of the pictures:50% battery remaining after morethan 24 hours of phone use (with wifi enabled)
How to use settings:
The frequence define in “Lock” will be used to lock your cpu at lowvalue.
“vibrate” option permit to know when the CPU is locked.

You can manage CPU settings with this app too.. (without using lockfunction).
An option has been added what permit you to listen music withlow CPU set.
Ex:If you set 100Mhz at lock, it will not be enought to listenmusic. The program detect you listen music and set higher CPU Valueto permit you listen it..Original value are set back when headsetare unplugged..
