Re: AT&T 3G Microcell Battery Drain
I believe I'm having this exact issue with my iPhone 4S on IOS 5.0.1.

I am trying an experiment where I turn Cellular Data off and on to see how it affects battery drain. I am about 90% sure the Microcell is the issue and Cell Data is the problem. I had the MicroCell off for all of last week as an experiment and my battery life increased at least 50%.
