    My iPhone 3G showed a full battery for most of the day, then all of a sudden i checked my phone about an hour ago and it was off. I tried turning it back on and the battery was dead and had to be plugged in.. Anyone have this same problem? Is this another 3.1 issue?

    Did this happen before 3.1 for you?

    We're you running an app and didn't know it?

    When was the last time you restarted the device prior to it going dead?

    Similar issue

    I've noticed since I've been on 3.1 (including Betas), that my phone does the same thing.

    What typically happens this the following:

    Battery over 3/4 charged
    I'll use an app/ (Slacker, X-maps, or a few others)
    Close out of the App
    My phone starts to get really hot. I'll put it down.
    I'll go to use it a little while later and it will not respond. (still very hot to the touch)

    Then after about 3 to 4 hours of not touching it and it's finally cool, I'll try plugging it and it will show the battery drained.

    Took it to the Apple Store. They told me it's probably an app that is corrupted. I could either A) Restore and setup as 'New' or B Purchase a replacement for $199. (Since I've had mine from launch of 3G)

    They claimed that when apps get corrupted it will hang and continue to run in the background and while trying to use other applications, which will start to over tax the phone causing it to heat up and then to shut down.

    I've have discovered anytime that my phone starts to get hot, shut it down, power it back up and it's fine. (because it's still doing it)

    Funny, the exact same thing happened to me today as well. My phone showed 100% all day, up until the point where it shut off.

    I'm still on 3.0.1, so it's apparently not just a 3.1 problem.

    This happens to me about once a month. A reset usually fixes it.

    I resarted the phone last night before connecting it to charge.

    This never happened before 3.1 and this phone is a white box replacement I just got 2 days ago.

    I was running a couple of apps but can't pinpoint which one. It's been running hot since I got it. Apple told me to restore as new and manually install everything back, which i did but it didn't fix it. Should I restore as new and not sync any apps until there is a new update?

    If corrupted apps are the problem then how do you identify them and know which ones to remove?

    3.0 too. This is exactly why I restart my phone throughout the day at least one time. Theres always problems.

    Everyone else should restart every day too. It helps...especially if you have a JB phone.

    Gonna try to restore as new again and not install any apps.. I have an appointment Wed at the Apple store.. I'm still gonna go regardless and this time i will be taking my Macbook Pro with me to get this straightened out right there on the spot. I'm tired of taking trips back and forth there.

    you should let your iphone battery die out once a week

    im pretty sure it makes your meter more accurate

    APPS ARE NOT CAUSING THIS

    do a hard reset (hold the power button+home button until your device turns off, do not slide it off)

    see if that helps

    turn off push on your accounts and other programs ( aim, text+ etc)

    if that doesn't work take it back to Apple
