Anyone else having this problem. I installed 4.1 yesterday and my battery is draining twice as fast as it did on 4.0.2.
surprisingly better [iPhone 3G]
so, not only did Apple fix the performance issue, but improved battery life as well.. what the hell is going on?!
4.1 installed on 4G and my battery life is less than half of what was. I took it off the charger at 9am this morning and at 2pm it was dead. Normal usage. Not JB. It seems that a lot of people are having this problem. Google: ios4.1 battery life. There are dozens of forums addressing the same problem, I don't see a solution yet.
