AMP Lab is not out to make money, nor to steal your information. Instead, Carat was built by a team of scientists from the UC Berkeley electrical engineering and computer science department’s AMP Lab (Algorithms, Machines, and People Laboratory). In a blog post, AMP Lab said,
"Using data from our beta deployments, we have already identified thousands of energy bugs manifesting in the wild. Carat not only detects such misbehavior, but assists diagnosis by correlating with device features like the operating system version and what resources are available (e.g., WiFi or GPS).
"Energy bugs" are apps that are using a lot more power from your specific device than other devices that Carat has measured them running on. Theoretically, they are using more power than on other devices because they are possibly malfunctioning; it that so Carat would recommend that you restart or re-download them.
"Energy hogs" are apps that just normally use of lot of power or run in the background, such as streaming music apps.
Some of the conclusions already made from AMP Labs beta deployments include:
- In an initial test with just 100 users, Carat found 35 apps with "energy bugs."
- Since then, Carat has found thousands of other energy bugs on devices in the wild
- Skype, Yelp, and Pandora are some of the most popular energy hogs. They require more power than most apps and could be among those that are best to temporarily kill.
Carat can be found free in both the App Store and Google Play.
