Top of a huge pile I've used a million apps of this type, and this one is simply the best of all. Only two caveats: (1) you can't install non-market apps when the battery bar is on, but you only have to turn it off until the install is done, and (2) there's really only one style for the widget that isn't ugly as sin, but at I guess at least there's one...
Makes it easy to monitor which apps drain power I have had this installed for ages and I'm very happy with it. Favourite feature is the graph showing power used over time for each app. This allows you to understand which apps are draining you precious battery.
Notification doesn't show up lack of data connection stat, incorrect high forecast hours, lack of battery temperature overheat alert
Widget temperature only updates after pressing it to go into app & come back out
Recent update eats battery This is a good app but a recent update has made this app redundant as I save battery by not using it.. Please fix.
Great! It's been very helpful with identifying which apps drain my battery!
