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 :(

Не хватает вывода текущего уровня потребления (или другого показателя на выбор) в верхнюю панель вместо ненужного значка.

Good App, but works not on every device - on some it displays app name as something like "app_10286", so it impossible to understand what app is consuming power.

A useful app Thanks for developing this app. This is the most accurate app I've ever launched for battery consumption. But it's regret that wifi chart doesn't work. I hope you will continue to develop and improve this useful app.
