This app will tell you which app is killing your battery
Normal is a battery diagnosis service that suggests personalized actions you can take to extend your battery life. By aggregating data from hundreds of thousands of users, Normal is able to accurately and precisely pinpoint the battery hogs on your device, tell you whether or not this is also happening to other people, and project by how much time you will extend the battery by killing each hog.
Using Normal is simple: Install and run the app, perform any actions it suggests (at your discretion), and watch as your battery life increases!
Normal works by collecting generic usage data on your device over time—including what apps are running, what type of device you have, and the battery level—and aggregates it on our cloud platform. Normal then analyzes this data, along with data from all our other users, with proprietary statistical algorithms designed at UC Berkeley’s AMP Lab. The results, in the form of suggested actions and statistics about the battery impact of your apps, are then sent back to you.
The app is priced at $0.99 on itunes.
