Tried an experiment today for battery draining
Froyo 2.2 unrooted
1. Uninstalled Task Manager that I had.
2. Turned off the following Widgets
3. Left on
Power Setting Widget
4. Logged out of Facebook App (latest version by the way)
Yesterday I didn't even get 10 hours until I was at 10% battery
Today I am 14 hrs plus and still have 40% battery left. Same usage if not more today.
Maybe the Widgets are the bad guys.
Just a thought
