Real power metrics I've been looking for an accurate power use app with this much resolution for a while. First dialog warns of possible incompatibility but everything works great. Logging is terse. I'm amazed at the apps that run on their own like rude guests who unnecessarily turn everything on and leave it on because they can. A battery has only so many charge cycles. Thanks for the best power metric app.

Avoid I must admit the idea sounded great, but my GS3 is not supported. I cannot see anything beyond screen and CPU use and they vanish after a while too. All numbers to zero. It slows down the phone, eats the battery and completely ruined my home screens.

Galaxy Note GT-N7000 w/RocketRom10 & Speedmod-13. A nice little app. But the WiFi power graph does not work. It gives 0 all the time, regardless of WiFi state, whether it's ON or OFF. Also the GPS and Audio, don't show any values in the graph (when used). Only Total, CPU & 3G graphs work.

Perfect to see what app is eating ur battery but... My phone Samsung galaxy w is not supported... Power tutor uses more power than any other app

by A Google User the 8/10/2012

Good, but could be better! The only pitfall is not working on all types of phones; I'm running it on a high-end development device from HTC, which many components (like WiFi, GPS, 3G) does not work on it. It could be best if it was similar to Trepn. For instance the graph could not be save, but a very primary log file! But still a good job :)
