[APP][4.0+] LazyCPU: Saves your battery topic

Hi everyone,

I want to promote my app "LazyCPU"

Firstly, I must say that application needs rooted rom.

It's a battery saver application which can saves battery up to 2+ days with managing CPU governors from kernel variables and it's blazing successful.
The idea is so basic that if the screen is off, change cpu governor as powersave, otherwise everything is restored.
I have tested on two devices Nexus 4 ( Android L Stock rom ) and Galaxy SIII GT-i9300 ( CyanogenMod11-M12-i9300 ). My galaxy devices battery reached 3 days for daily usage ( full time wifi open, whatsapp, chrome app etc. ) :) Nexus 4 device's test started yet but the battery indicator decreased only 3% for 5 hours.

I'm newbie at here and I'm not allowed sharing link at forum, you can find it at Play Store.
I will upload apk files next time :)

Thanks for your feedbacks.
