Battery life is one of the most important factors for anyone out there to buy a smartphone. And now with upcoming battery-hungry technologies life 4G LTE, there’s not much that device manufacturers can do (except increase the battery size). But not many of us know, that more than the hardware, it’s the software that impacts the battery life.
So what exactly is “Collaborative Energy Debugging”? Carat is based on collective effort from other users – the longer you use it, the better it should work for you giving more accurate results, at least in theory.
To use Carat, you need to install and run the app on your iOS or Android device. The app intermittently takes measurements about your device and how it is being used. These measurements are sent to their servers, which throw them into a big statistical stew and try to infer how devices are using energy and under what circumstances. The results of these analyses are then sent back to the app, which can give you feedback and actionable advice about how to improve your battery life.
Carat provides a great deal of information about how energy is being used on your phone. Remember that the information displayed by Carat changes over time as it learns; the longer you use it, the better the results get.
The main screen presents an Action List, consisting of actions like “Kill App X” or “Upgrade the OS,” along with an estimate of how much your battery life will improve if you take that action.
Carat has been developed by a team based out of the AMP Lab in the EECS Department at UC Berkeley, collaborating with the University of Helsinki.
