Concise & to the point answer:
1) Greenify works on both rooted & non-rooted devices (more features if rooted).
2) & 3) Forget "battery saving" apps,as a whole,they don't save anything,they're typically spyware,filled w/pop-up ads/etc.....

4) Any more ?'s on the subject,give this thread a thorough read,ALL of it,& you'll see why "battery savers" should be avoided like the plague...............
