that particular screen does not give enough information.
You need to know what apps are running and if they are necessary for the way you use your phone.
I have my phone battery use screwed down very tight, and can get through a day w/o use on about 15% battery consumption.
With moderate phone calls and a few text messages, i still get about 3 days per charge.
but, I have it fine tuned. Read the battery threads, and get an idea how each of us program our phones differently and get different results.
this thread is for the frugal minded geeks like myself, you will see me post on that thread.
