iPhone battery draining faster than normal

[KStewart]

Ok, well I started this thread about a significant battery problem so I guess that is where the confusion was. Glad to hear your phone is working normal.

No problem...and my phone isn't quite normal. I just wanted to add that there was battery loss for me with 2.2.

Wabbit,

You were able to go 2 days before recharging??? I've always had to charge at least 1-2 times per day, which I think is pretty typical of all 3G phones and moderate use.

Personally, I think lasting 2 days might have been a bug in itself...

i was avg 36 hrs, with web browsing / email / phone. basically from 1 morning to the next day bed time i would actually charge it or it need one.

the phone runs hot now, i can feel it through my case, which i never did, i did do a restore, the other memory went down from 350 megs to 230ish or about off the top of my head, the phone still runs hot, and gets about 6 hrs of battery life. its all firmware. 2.1 worked fine, 2.0.2 worked fine.

Read a post that said Push Exchange email was always on and he deleted the account and reset and that worked - really improved battery life. I don't have Push Exchange, but found out I had Push MobileMe email on. Since I turned that off battery life has really improved. Getting my email updated every 15-minutes is fast enough for me.

Mine holds really well until about 50 percent battery life, after that it drains so fast that within an hour I can be in 20 percent just on stand by. Its happened to me 2 or 3 times in the last couple of weeks. Sometimes I think its the internet trying to load a page. I can click safari and its finishing loading a web page.

Oh ya I forgot, I often charge it in the morning for the new day ahead and I can have 60 percent life when I do so. Is this bad? Is it like a laptop battery where you should let it fully drain before charging it?

I think part of this is just the way the battery functions. It will take longer to get from 100% to 50% than 50% to 0%. Just like when you are charging it takes longer to charge that last little bit. You can be at 20% and within 30 mins you will jump up a lot, but to get back to 100% takes time. Mainly from like 80% to 100%. I kind of think about it as filling a balloon with air. It's really easy to start filling it up, but as you try to make it more and more full it's harder.

I do not use an exchange server. All my emails are setup as IMAP.

Ok its official by battery is like fried or something. I used to go two days without a charge now I can't get 6 hours. With little use mostly standby. I am getting annoyed big time.

Found it seems to be email getting hung up or stuck in the connecting mode sometimes so its like constantly checking the servers. I have both an exchange account on it and another regular account set on fetch for every hour. Seems like 2.2 caused a problem with this. All was fine in 2.1.

Now I have not been following your story here but have you restored yet? Honestly that is the only thing that will probably fix that issue.

Yeah, just do a restore...worked for me.

Does there seem to be more of a problem with the 2.2 upgrade than the 2.1? I can't really tell since I had a problem with 2.2 so I am noticing it more, just like you start noticing cars on the road after you get a new car of the same type.
