ok ok ok first ideal profile is not important to be 750 i mentioned in the first post that if you noticed any battery effects just make the max freq 600 and for people having problems with the tweak i think you are using a lot of auto update apps in my case : i disabled auto wifi update / connect disabled all repositories (i enable them only when i need them) configured any auto update app to manual update i can't help any further sorry btw i'm trying some other battery tweaks will see how it goes with me
