Berkley scientists launch Carat, an app to monitor phone battery usage
| by Padmini Harchandrai |
A group of scientists at the University of California at Berkley have developed a mobile application that monitors your phone's battery usage. The application will tell you which of your phone's other apps are draining your phone of its battery and which apps contain the most number of battery draining bugs. They wrote on their website, "An energy bug is a system behavior that causes unexpectedly heavy use of energy and which is not intrinsic to providing the desired functionality. We aim to identify and help diagnose energy bugs in mobile devices by performing distributed, low-overhead sampling, aggregating these data, and applying statistical methods to identify the apps, behaviors, and configurations that are associated with high energy consumption."

The application essentially can tell you that using your favourite e-mail application is draining a large amount of your battery when you're using it over GPRS/3G, as opposed to over Wi-Fi. Furthermore, the developer behind the e-mail application can be informed of a bug that might cause the issue and, of course, issue a fix for it. The website essentially says that the service informs users of what's draining their battery in exchange for usage data. They write in the application description that the data is collected from your phone and delivered to their servers where they apply a number of algorithms to give you your results. However, they specify that none of the data they collect will be able to identify you personally.
The Carat description specifies that apps can either be considered 'hogs', where they intrinsically drain a large amount of battery, or 'bugs' where they contain bugs that will drain battery. The description says that neither of these two things are necessarily bad, however a smartphone user could use this information to adjust their behaviour.
