Still a problem, or at least it was for me and I am on 2.2.1. What gives?

ok so I updated to firmware 2.1 and then I noticed I started having problems with the battery. So like if I charge it for 12 hours and then use it then a couple of hours later the battery goes low when i hardly used it. And when I get home to charge it right before i plug my Iphone in the batter is red so when i plug it in all of a sudden the battery turns green after a few mins its been plugged in.

I have the same problem with my iphone.. eversince i upgrdade to 2.1, my battery drains faster than usual… so i have to charge 2-3 times a day and my phone is always warm. Another thing is when i left it overnight with its battery about meter was on 75% and then as i wake up and check the phone it is almost drain. I think it is really in the 2.1 firmware.

In the end of last week my battery suddenly dropped to zero in no time, and the phone was very hot, although I didn't use it.

The usage statistics indicated that it was working all the time.

I did a reset which didn't help at all.

I deleted my Exchange account and reinstalled it (push, mail & calendar) and now the phone is back in business.

So my exeperience is like someone else here earlier: the push functionality seems to get stuck in some kind of endless loop which can only be stopped by deleting the account and reinstalling it.

Thanks for the comments. I have had a recent drop in battery life in the last week for no “apparent’ reason. I turned on mobileme about a month ago and didn’t notice anything. But starting on Monday, my phone would be almost dead by the end of the day when i had not used it and the usage was WAY to high! I hope your suggestions work!! keep up the good work letting us know!

I have firmware v2.1 (and for some reason I can’t upgrade to the newest version – I get an error code). And despite replacing my old battery with a new battery, I’m still experiencing severe battery drain. Phone doesn’t last 5 hours w/o going from 100% to very very dead – even when left unused (such as overnight). I noticed problems after installing Pandora Radio, but I haven’t seen any other info on Pandora causing problems for others. Very frustrating. I don’t use mobile me on my 2G iPhone, but I do have push turned on for Email. Any ideas?

So I have found people with similar problem. I turned on push a some mont ago, mail, and it worked with no problem. A few weeks ago I also turnedon push-calendar, still everything ok. Then, a week ago, I finally turned on push-contacts and then, one or to days later, I found that the battery emptied in rapid speed, and they day after that, it again emptied in rapid speed and went really hot. I turned it in to the reseller so will see wath the reply will be. PS I also claimed a new cover cause of the crackings in the cover

Just had to toss this out here, I think its great we try to find workarounds for the iphone. Esp with all its feature rich applications etc, but heres a concept how about making a battery than can handle all of it? Meanwhile were left scrambling turning off EVERY possible feature to make this phone last for barely 8 hrs? Cmon, I adore the phone overall but I think apple needs to really look into this & hard. The blackberry storm is coming out shortly & if there is little reported issues at that time this cats switching. I refuse to babysit/nurse this phone for years till apple figures something out & at/t gets theres 3G network full covered. Which is another issue in itself, guy told me that it will take 3 yrs for At/t to fully upgrade all there towers-thx at/t till then what ???
