Carat


** PLEASE READ BEFORE INSTALLING **

Carat is the first app to generate personalized recommendations for improving your battery life. After observing your use of the device for *about a week*, it will start to generate reports just for you.

Carat uses GPS sparingly and is NOT running in the background. The app uses almost no power.

** Thank you! **

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.

And it's free!

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.

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
- 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 started at the AMP Lab, UC Berkeley, in collaboration with University of Helsinki. It is under active development by a team of researchers in the NODES group, Department of Computer Science, University of Helsinki. We are constantly making improvements, adding features, and giving you more knowledge about how your device is using energy. Remember, knowledge is power!

Carat must be hallucinating I've had this app a long time, across three phones. There was a time when I had a phone that required me to be very battery-aware. Even then I wondered why Carat would recommend I kill apps that I never used. I paid attention to what it suggested but I acted on few, in any, because they rarely made sense. Now, with my Droid Maxx, battery life is not an issue,. And with Kitkat 4.4.4, Android Settings>Battery is telling me that all the apps Carat was so wound up about are not a concern at all. Uninstalling (finally).

Worked on my previous devices But now on the LG G3 over updated for over a week and it still hasn't told me what is draining my power. It still hasn't given any suggestions and is still asking to open every day. For how long? 4 stars because it did work before, need it to work again.

Bad interface and asks for too much permissions.

For what? This app seemed to have promise, but in the many months I've faithfully uploaded data to it, it has rarely if ever given a practical recommendation. Everything it wants killed simply respawns. Now, its constant nagging to send samples has driven me to uninstall.
