Save your battery and disable the second core of your android device when you dont need it!
!- This app is only for dual core devices made by Samsung -!
This app should work on most android dual core devices from Samsung (maybe also on others but these are untested!). Please report on which devices the app works and on which it doesnt. You have to be rooted! Every time you reboot you need to redisable second core! If the second core starts again at some time use another governor. Not working with hotplug!
