Exactly does what its supposed to do I had serious battery drainage problems and I couldn't find the cause of it  I tried different apps but non of them helped me as much as this app did. HOWEVER  you should keep this in mind that this app works best when you have a rooted phone. You may also consider using this in conjunction with androids battery stat (in your settings) to be able to solve your battery drainage problems. I would've 5 stars if it had a knowledge base built-in so you don't have to Google wakelocks.
