I have been having issues with battery life since I purchased the phone on Friday the 6th. I've read many posts with different suggestions (dl'ed Automatic Task Killer, *228 option 2, etc.) and tried them all. One thing I have noticed is that my signal strength goes from Full (4 bars) to Zero (no bars) while sitting on my desk at work. I don't touch the phone or move it at all, but the bars will go from full, to nothing, back to full. When there is no signal I know phones will expend battery power searching for a signal. So this might be part of my issue. Is anyone else experiencing something similar?
