    There are two types of "Push" things.
    1. Push Notifications - something new introduced in 3.0. Allows 3rd party apps to push information to your phone.
    2. Push email, contacts, calendar etc. which has been enabled since the iPhone 3G was launched.

    Therefore there are two ways of disabling these things:
    1. Push notifications are turned off by going Settings -> Notifications -> On/OFF
    2. Push email etc is turned off by going Settings -> Mail, Contacts, Calendar -> Fetch New Data -> Advanced -> Go into each email account and set Push to Manual/ Fetch.

    AHA! I may have found the problem, for me at least.

    After changes, my battery has lasted:
    1 Day, 1 Hour in standby.
    4 Hours, 50 minutes usage.

    _Some improvement on my half a day battery life results before._

    *Here is what I did*
    I forgot to turn off Push Notifications - the new feature introduced in 3.0 for 3rd party app notifications. I have TapTap the game installed and this asked for push notification access when it updated after my upgrade.

    Since turning it off yesterday at 14:00 BST, my phone has lasted till now, 15:40 BST today, and the battery usage bar looks as though it has 1/4 charge left, although this could mean 5 minutes for all I know!.

    *Here's my settings:*
    Software: 3.0
    WiFi: ON all the time
    Bluetooth: ON all the time
    Push Email: ON for Exchange account
    Fetch: ON 1 HOUR for 1 account
    Location Services: ON all the time
    Backlight: 50% AUTO
    3G: ON


    Another thing that has me miffed, is my usage results that my iPhone reports. I didn't use my iPhone at all yesterday, yet I came to view my battery usage stats, and it reported over 2 hours! WHY!?

    Do you have any apps, such as IM+ that use push? Those often runn in background, even when no open. If they are not updated as 3.0 compatible, they may be causing your problem. My 32gb 3GS has everything on, push on for exchange and yahoo mail, location on, wifi on and connected for 13hrs per day, bt on and connected for 3 hours per day. Strong 3G signal at home, and a marginal one in my office.

    I've had the phone off the charger since 6am. 15min of calling, some emails and a text or two, with light surfing = 88% remaining after 4.75 hours. that extrapolates out to ~~39 hours of expected life, with Everything on......

    I think this is predominately a iPhone 3G issue, not 3GS.

    For starters the 3GS has an improved battery and comes pre-loaded with the 3.0 software, something that the iPhone cousin doesn't share in common.

    (no - no other apps running push notifications)

    Got to agree that is seems us 3G owners are the ones mostly affected by this battery drain-down thingy!! Come on Apple... let's get an update out there... please.

    experienced same problem.

    Another problem is, i can't read any formal replies or advisory from Apple.
    Are they reading our complaints? (disregard this questions if there are any answer)

    Are they reading, yes.

    Replying, none that I've seen thus far.

    Apple will probably not acknowledge any issue until a FW update is ready for release and even then will likely not make a formal statement beyond posting the fixes in the version. If you're under warranty, and don't mind the hassle, take the phone into an Apple store for a diagnostic by an Apple Genius. They have a new software tool that will show them all kinds of fancy stuff about app usage, heat, crashes, etc. If they see an issue the tool also tells them what to do; replace, etc.

    One thing is for sure - if they start seeing a quantity of FRUs flowing out the door due to heat/battery problems someone up at Apple HQ will get the memo.

    Voices can be loud, but nothing grabs attention like money - especially when it's flowing out and not in.

    I've had nothing but problems since upgrading to 3.0
    I had to restore the iphone twice in the first 2 days, the battery goes down so fast that even charging it while driving in the car doesn't keep up
    Now, it went dead today and I can't get it to come back after being plugged in for over an hour.

    @Skippo88

    Just curious - I don't have a Settings -> Notifications section. Is that something specific to a certain model?
    (I've got an iPhone 3G 16GB)

    pretty savvy normally with these things, so i'm surprised at myself...

    @kahuaina:

    There are a few reasons why you might not have this option:
    1. You don't have OS 3.0 installed
    2. You don't have any applications installed which take advantage of the new push notification service as part of OS 3.0

    I didn't have these issues when I upgraded to the 3.0 software, now for the past few days I do.

    I deleted the only new app I had downloaded (although a few others have updated). I didn't have anything that used Push Notifications.

    I usually keep ALL the other things off: Location Services, WiFi (unless at a hot spot), Bluetooth.

    I did have an Exchange account, and a MobileMe both doing push, but they've both been set up that way for a long time before and after the 3.0 software.

    I took the advice of someone else in this thread: Installed the free AP app to get access to the Push Notifications setting to turn it off. Hopefully that improves matters.

    Just wanted to add a "me too," although I'm not totally convinced it's the 3.0 software.

    I think these problems has something to do with the software i installed and using. I experienced my iphone overheating when i'm using the map application and it continue heating when i use at the same time the motion GPS Lite.

    iphone is not designed for a really serious GPS application. It will eat up your battery like pacman

    Just my 2 cents

    Does anyone know if the current update to 3.0.1 addresses or improves on performance of battery life? I've had the same issues as listed here and I've been through THREE replacement iPhones. No help other than replace the phone under warranty at the Apple Genius Bar.

    Thats all they will do. Apple will say its something they are looking into. Make sure you have ur Apple Care Protection transfered to the new phone. I went through 8 and each time, it wasnt carried over. I have to call now because they said the Apple Care for my 2G phone doesnt work with my 3G and Im starting to get upset!
