Carat is the first app to generate personalized recommendations for improving your battery life.

Ever wondered why your battery is draining so quickly? Just install Carat, open it every few days so it can send data to our servers, and within a week Carat will start recommending Actions (just for you!) and even predicting the improvements you will see. Although Carat cannot measure energy use directly, it infers what apps are responsible using advanced machine learning methods.

As you use your device, Carat occasionally takes measurements and sends them to our backend servers in the cloud, where we apply cutting-edge algorithms to determine what steps you can take to use less energy. By collecting snippets of non-personal data from a large number of devices, Carat does not need to run continuously in the background. Nothing we collect identifies you, personally.

NOTE: Although Carat uses Location Services (thus displaying the little icon), it is NOT using your GPS and is NOT running in the background. The app uses almost no power.

Carat will tell you which apps it thinks are hogs (they use a lot of battery) and which are bugs (they use a lot of battery on your device but not most others). Being a hog or a bug does not make an app ‘bad’, but a user trying to improve their battery life can use these designations to adjust their behavior.

Carat Features:
– Action List telling you how to improve your battery life and by how much
– Device information detailing exactly what data we are recording
– Reports apps that are using lots of energy and whether that is happening on other devices, too
– Detail views let you dive down into the data and see graphs of energy use
– Low-overhead sampling requires almost no energy or CPU
– J-Score tells you how your battery efficiency compares to other users
– Sharing features let you post/tweet/blog about your experience; more users means more data which means better recommendations for you

Carat is under active development by a team of researchers in the AMP Lab at UC Berkeley. We are constantly making improvements, adding features, and giving you more knowledge about how your device is using energy. Remember, knowledge is power!

Our Review:

Carat is a useful app for every iOS user. There are a lot of battery management apps in the app store. Most of them charge premiums although they can’t do anything effectively. Most of these apps just notify you how much battery life you’ve got left while you are browsing or doing something. But Carat tells you how much battery an application is using. Carat turns down your brightness when you don’t need it. Don’t need to kill your apps like Viber that constantly run in the background. You can find the buggy apps that are using battery unnecessarily and cut it down by using Carat app. As it is free you can try this app.

Requirements: Compatible with iPhone 3GS, iPhone 4, iPhone 4S, iPod touch (3rd generation), iPod touch (4th generation) and iPad. Requires iOS 4.3 or later. This app is totally free to download from iTunes.
