Stumbled on this string again and thought I would give an update.
There are times when my phone seemed to use more power, but it always has made it through a day.
I am checking the stats now:
cell standby 25%
phone idle 23%
The bluetooth, wi-fi and GPS are on full time and have been that whole 22hr.
I find with heavy display usage, battery life drops, but that is expected.
I am not a heavy user and so I get longer life. If you are a heavy user, then you can expect a need to do something about it.
The one person who was having a problem with GPS usage with it off is sometimes not caused by the GPS, but by a program trying to use the GPS. The constant attempting to talk to the GPS could burn up some juice, like being in a loop, and pointing the finger at the GPS. Might even take less power to turn on the GPS
