I'm 99% sure that its almost entirely to do with your signal strength.
Searching for signal seems to really kill this battery, especially when switching into roaming.
I found that where I work, I have zero sprint signal and roam 100% of the time (which is ok, because I don't use the cell at work much). I noticed that my phone won't even last the whole day unless I charge it at my desk.
However, on the weekends when I'm home and have perfect service all day, the battery will easily last more than a day.
I think the reason some of us have worse battery life than others has to do with where we live geographically.
Something that I've found helps a little bit is to put my phone into "roam only" when I'm at work. That way, its not constantly looking for another Sprint signal, and it seems to last the day like this.
I'm dissapointed about this since my HTC GSM phones could go days without a charge.
