:I have a 1st gen iphone and I stuck with the original 1.x firmware for a while. A few weeks ago, I upgraded to the 2.x (currently using the latest whatever it is at the moment) and since then my battery life simply sucks!
Usually I could get about 2 days of life out of my phone there are times when it will just die in hours. This is with it sitting on my desk doing nothing. In fact, I just charged it to full, went out to lunch, came back and an hour or so later I go to check something and I see my phone is "off" because the batter died again.
I am not using push email. I have POP mail configured to check every 30 hour or so. I have a few apps but I can't see them being the problem. Any ideas?
Going from fully charged to dead in an hour is unacceptable - I don't even think a process running in the background at full CPU would kill it in an hour.
