This app has helped me save alot of battery since I've installed it. In 8 ours I only used about 14 to 15% of battery!! https://play.google.com/store/apps/details?id=com.gsamlabs.bbm&hl=en
Can't post screenshots at the moment because I dropped my esteem and the battery fell out so the graph started over.
