My iphone 3.1 battery life is just atrocious. I noticed about 2 days after upgrading that I couldn’t make it through a whole day without having to recharge it. A quick search of the newsgroups reveals a host of theories and recommended things to try. I did all the basic ones, turning off push notifications, Bluetooth, etc. In the end the only thing I have found that seems to work is putting the phone in “airplane mode” when I don’t need it.
Everyone I talk to has a slightly different experience, and there are a few 3.1 users who aren't having an issue. My personal conspiracy theory is that AT&T enabled a new section of spectrum around the same time apple released the 3.1 upgrade and some combiniation of the two has resulted in half-lifeing my battery.
The 3.1 release is probably a pass, it has it has a number of bugs, my data connection always thinks its working when I have no signal, they disabled my tethering ability (which I live by), and they broke exchange support. Sadly like all apple upgrades there is no way to downgrade.
The sad thing, I still LOVE my iphone. I feel like such a techno-lush.
