Battery power on an iPhone or Android phone is always a bit of a crapshoot. However, Carat is an app that shows you which apps suck up power so you can shut them down and improve battery life.
To get the most out of Carat you need to start it up and let it run in the background for a couple days. Once Carat collects some data is shows you which apps decrease your battery efficiency. It then provides you with an action list that tells you how you can increase your battery life by shutting down certain apps. Carat is by no means a pretty looking app, but it gets the job done. It’s also one of the few battery tracking apps to give you useful data. If you’re battery on your iPhone or Android has been sluggish lately Carat is worth checking out as a free download in the iTunes App Store and on Google Play.
