User reviews of PowerTutor
Excellent app when used as a tool in conjunction with JuiceDefender and something to control which apps and services start and run in the background. I use Android Assistant and Super Box. Using these and monitoring over a few days I saw which apps were using the most power and either changed their settings or stopped them from starting. This method has given me about 60% more battery time and I'm still refining it. This is the first comment I've ever made but this made such a difference to me I felt I had to. 5 stars

Useful enough to discover that it drained 10% of my battery. Thanks for let me now. Uninstalled.

App warned at startup that my phone (Samsung Fascinate) was "not recognized". Since it says "runs on most Android phones" I persevered, but was disappointed to find no App Power Usage info was ever displayed. The System Power Usage Chart/Pie/Stat views looked most promising however.

Fantastic app for monitoring battery usage in a proper, usable way. The notification icon is a bit ugly considering it is always shown and the log file writing is flaky. Otherwise, works great though and finally gives you some real information about battery drain

Seems fine for short-term monitoring (an hour or so), but if you leave it longer, the "save log" feature will crash. I was trying to monitor power draining apps overnight and lost all the data on a force close when trying to save the log :(

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. Power Tutor still works on Moto G running JB/4.3. Avg charge lasts 2 days with PT help. Thanks for the best power metric app.

Frißt selbst zuviel Akku Die Geräteunterstützung ist leider zu gering, auf meinem Nexus 7 wie auf meinem Motorola Defy lag der Akkuverbrauch über Android-System. Sowas geht gar nicht. Wenn mehr und aktuellere Geräte unterstützt werden, werde ich es nochmal testen. Bis jetzt gibts daher leider nur 1 Stern.

Good, but not great The pie chart view is very useful. However, the app puts a notification icon in your notification bar, that you cannot dismiss.
