    Save Battery and manage your cpu with one application. (and free)

    /!\ Need root device /!\

    How it's work:
    It save battery by blocking CPU to it minimum value when we don't need it (when the screen is OFF)\n

    You don't need power when your screen is OFF, and your CPU is still using at maximum frequency by program (in background) so this will lock to very low frequency your CPU and permit you to keep battery.

    Up to 3 days autonomy !!!
    You can see on one of the pictures:50% battery remaining after more than 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 low value.

    "vibrate" option permit to know when the CPU is locked.

    You can manage CPU settings with this app too.. (without using lock function).

    An option has been added what permit you to listen music with low CPU set.
    Ex:If you set 100Mhz at lock, it will not be enought to listen music. The program detect you listen music and set higher CPU Value to permit you listen it..Original value are set back when headset are unplugged..

    All options included:
    -Detection of incoming call to restore cpu before answer.
    -Detection when Music is playing to give enougth power to your phone.
    -Detection of Clock alarm to permit you to stop it correctly when you wake up.
    -Rescue Mode if you have any issue with detection

    Feel free to ask me by email (
    If your device hang\freeze on specific value, it's come from your kernel.

    To make it work, set the next value avalaible.

    If you like this app, let some stars on market ;)

    It works in setting the frequency i ask it to, but i didn't want it to mess with the phone as soon as the screen is turned off.. Can you say if when i restart my phone and the Media Scanner is running will this not cause issue? I had to force close the app after the app applied the values on boot because as soon as i turn the screen off and turn it on again i see the app as been granted access which seem as if the app blank the phone out while the media scanner is running and i have alot of files to scan. Also on another test i disabled start on boot but the app still started on boot
