    I posted this in another thread regarding the Original iPhone but I think it applies here as well...

    Here's an extreme and slow process but it's likely to solve or find your battery problem...

    1. Restore as new (not from a backup) and don't sync any apps, music video, etc
    2. Don't sync or add anything to the phone, i.e. email, apps, etc.
    3. Calibrate the battery meter by fully discharging and the fully recharging the battery.
    4. Turn off Push, Wifi, 3G, Location services and BT.
    5. Use it just as a phone and see how battery life is
    6. One at a time, add the things that are most important to you, i.e. email, music video, apps, etc
    7. Check battery life between each one.
    8. If the battery/heating problem is solved, over time you'll be able to add all your 'stuff' back on. If not, you'll find the culprit. If the culprit is actually the battery, perhaps it's time to get it replaced.

    I realize this may take a while (a few days to a week) but it may be worth it to those that are having real problems.

    Thanks for your help, but Apple should do this!
    I'm not Apple's Beta Tester!

    I don't think you need to go that far- just use common sense! I sorted these problems out with my 3G in less than half an hour- not one week!

    FWIW, my 3G worked great 'til I installed the new version of AIM and enabled push for AIM. Now, my phone stays hot all day and the battery burns down in about 8 hours (was lasting at least 14 hours prior to installing AIM).

    It's happening for me too on multiple routers. Definitely a 3.0 issue. God **** Apple.

    OS 3 has Push notifications.. u need to turn it off!
  • Ben in Africa Level 1 Level 1 (0 points)
    So:
    I have hard reset and restored.
    I have erased and re-set up all my emails including the mobileme push one.
    I have no push apps on the iPhone.
    No Location on.

    If I turn the push off then three of the key advantages of the iPhone are lost:
    - mobileme sync, wipe, email notification.
    If I turn 3G off, then what's the point of a 3G phone?

    Where's the logic of selling a phone if you have to turn most of the value-added features off to ensure the phone lasts barely a day (let alone 2-3 days for other 3G push mobiles, e.g. Blackberry)?

    There's a design problem or a battery related problem - either way, Apple has a problem.

    I have tryied to monitor the battery.
    Witj push notifications is the same if they're off.
  • KeithBerry Level 1 Level 1 (0 points)
    Thanks for all the replies.

    I tried a lot of the things mentioned here. Turned off Wifi, Location and Push - that didn't make any difference.

    Last night I deleted all my email accounts, interestingly the email accounts seemed to still be on the phone, until I did a hard reset. After the hard reset, I left the phone all night - and had virtually no battery drain.

    So this morning I added back both email accounts and battery life seems to be fine now, back to it's pre OS 3.0 life.

    I have the same problem since i have installed the OS 3.0 to my iPhone 3G. The battery depletes in a few hours even if I don't use the phone at all.

    It definitely has something to do with the new 3.0 software.

    Hard reset = restore the phone to factory settings?
  • techsutra Level 1 Level 1 (0 points)
    Hard Reset means holding down the power button and home button together till the silver apple logo appears. I had the same problems with OS 3.0 and I have documented the steps I took to solve the [OS 3.0 battery problems|http://www.manu-j.com/blog/fix-iphone-os-30-battery-charging-problems/ 353> in my blog post. Hopefully a fix is forthcoming
  • ixocean Level 1 Level 1 (15 points)
    Having the same battery issues with the 3.0 upgrade on my iPhone 3G; 5-6 hour discharge, warm/hot phone, iPhone refuses to accept a charge unless everything is off - wifi, telephone, push, bt, etc.

    I should note I had similar heat issues with the 2.x FW, and the Apple Genius replaced the phone saying that the heat was due to use. My question to him at that point was two-fold; why buy a phone if I can't use the features, and will Apple address the overheating in the 3.0 FW. He would only say FW cannot address a hardware item. At that time I thought perhaps the 3GS would fix my problem, but I'm hesitant to upgrade as it seems the 3GS owners are also having overheating issues.
