can anyone reccommend a battery saver/extender app

[tonyvr4]

I have been using a battery saver/extender app by cheetah mobile for a while and they changed the app recently to include tons of ads.
I am tired of their ads. Can anyone recommend an app what extends battery life but without the ads? I have not problem paying for this convenience

Try Greenify, it's very effective and uses hibernate, try to avoid those task killing apps. Greenify shines with a rooted phone but works pretty well even without root.

Is that greenify or greenified? I saw both in the play store
Does it optimize the battery while charging?
