    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.

    My battery life seems to be the same from 4.0.2 to 4.1. Today is the full day, so I'll get back to you after today is over.

    I notice this morning that, after a full overnight charge, I'm down to 79% after only a couple of hours. Hope it improves...

    I have noticed the exact opposite. It has gotten better. Not a lot, but a few percentage points.

    I have the exact same problem. After I updated the phone, I barely would even have it on, and my battery was draining like crazy. I never had this problem before this recent update, but now it seems like anything I do kills my battery. It is quite frustrating.

    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?!

    I upgraded to 4.1 last night and did a full charge overnight. Turned on the phone 7am this morning and have been using it for mail, pictures and text messages and the battery has been steady. No gaming though.
    Curretly 6 hours later, the batter is at 75% capacity.

    Performance should have been there all along. Apple Fail on that one.

    just out of curiosity, the ones with the power drain, are yours JB?

    mine is not, and mine is fine battery wise, just wondering if apple are able to target JB phones via the update and sabotage them?

    might be p**sing in the wind but you never know

    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.

    So what happens when the battery life is practically nothing. Can it be replaced?

    This is actually typical of all iOS updates. It helps a good number of users on battery life and sucker punches others. It could be that a third party app is causing an issue.

    Try letting the battery drain to where it shuts the phone off. Then give it a nice full charge and see what happens. It could be a software thing where the new update was installed when you had lower battery and it thinks of that now as 100%. Again let your battery die completely and then let it charge to 100%. Do NOT use the phone while it is charging back up.

    Weird...I'm actually noticing better battery performance on my 3GS since I updated to 4.1. No more lag either.

    I finished my day off on my iPhone 4 running the new 4.1. 13 hours of standby and 3 hours of usage. Push email for two exchanges, calendar pushes, 20+ emails, several texts, a few 5 minute phone calls, and some web browsing. I have 62% left.

    This is on par with if not better battery life than 4.0.2.

    I am obviously not jb since they are still working on that.

    Me, too. When I did the install, I had problems, and had to do a clean install - set it up as a new phone... so I was suspecting either a configuration setting or a rogue app... but my battery life sucks... and I have turned off just about everything that I can think of in the way of location based stuff, alerts, push email, etc... and still the battery life sucks. No jailbreak here, either.

    Mine seems like it's draining pretty fast was well.

    1 Hr 32 Min of usage
    4 Hr 3 Min of standby

    I am at 78%. I just assume it's the notifications. I always have lousy battery life with them on.

    i do this once a month or sooner, also when i am doing a FULL charge from flat i plug the phone in and as soon as it's booted up i turn it off to get a "clean" charge, never had a problem with battery life on my 3G and so far on the 4G still all good

    apple did do a replacement for $75 on the 3G, but it is cheaper by far to get your own battery for it off ebay and do it your self, it's surprisingly easy

    Hey Brian,
    I tired this yesterday after reading your comment on here. With 4.1 I was having bad battery. And the one of the main reasons i came back to Iphone was because they got a better battery. So usually I would get up at 8:30am and unplug my phone, do a little email reading/deleting/responding about 2 calls total 5 mins. By the time i got to work around 9:30am or so i was down to like 95%.

    After doing what you suggested I noticed a difference and today it was a busier email day and 2 more calls then usual... 1 hour later im at 98%.

    Hope this keeps up

    thanks

    it does suggest this in the user manual, most phones suggest this for every battery cycle but the iPhone uses a more sophisticated type thus only needs it once a month or even 2
