    I called Apple Care today and they have advised me to get the iPhone checked at an Apple Store and probably get yet another exchange.

    Regards to the battery - I have noticed some odd things too. The first time I charged the phone, initially the charge was around 70%, within 5 minutes the charge went up to 100%. When I disconnected the power source, the phone still thought it was connected to a source.

    After 2 clean restores, I noticed today after work that before I connected the phone to the power source, the battery was at 55%, and after connection, immediately it went down to 18%!

    Perhaps the self-shutdown issue is to do with problems with the battery?

    So it seems like this is a widespread problem, and the two things people have in common are 1) the phone keeps randomly powering off, and 2) this started happening after updating to OS 3.1.2.

    I called Apple Tech Support this morning. At first they offered to exchange my phone. Um, well, I have a first generation iPhone, so it's long out of warranty. Plus, as we all know here, it wouldn't matter a whit. A new phone with OS 3.1.2 would probably start doing the same thing.

    The tech then told me that OS 3.1.2 was created to fix some power management problems. It appears that they still have power management problems, albeit different ones. And he said that their engineers do read the boards. I hope that is true and that we're not just posting out in a vacuum.

    A fix sooner rather than later would make me happy.

    I just wonder why not all iPhones get this problem... there must be something that makes our phone susceptible for this.

    Either way I'm sure Apple wants to fix this. Because if they are doing exchanges for all the phones with this problem, there will be a lot of people going for this.

    I also have this problem on a first gen iPhone with OS 3.1.2 shut down 5 times this morning while trying to read email, safari, ans messaging. Batter life was around 40%, plugged the phone in and the power went away.

    This has happened to me and usually with battery life less than or around 50% (but never near dead).

    I have the same problem myself. Have the phone Less Than a week. I Updated The Firmware to 3.1.2 and walla.. problems.

    Does apple have a fix for this?
  • EricBarnes Level 1 (0 points)
    tried puting previous versions on and its not allowing me too.

    this only happens at night time for me.. which is quite annoying as the alarm clock wont work.

    i restored it (AGAIN) and will see if it makes a difference tonight

    I have bought my iphone 3GS on Jan 8th 2010 and after upgrade, it first stopped opening any installed app then it rebooted and now it is completely shutdown and not powering up by any means. I am planning to go to App Store but from this thread it seems that it is not useful going there. Can somebody advise me what should I do? Why Apple is silent on this problem and not making an urgent fix? Well, people say Vista was bad, but I'd say, iphone is worse than Vista...this is my first experience with iPhone, which has turned out to be nightmare for me. Is anybody from Apple/iPhone team reading and provide information back to us? If not, then it is a real shame on Apple.

    I've just tried to upgrade my 3G OS to 3.1.2 and it completely crashed, it doesn't even register in itunes when it turns back on. From what I've read, I'm on my own
    Any help would be appreciated as I really can't afford to have an expensive brick in my pocket.

    Same here. New 3GS 16 GB model 3.1.2 pre-installed. I get up to 10 or so random shut downs a day. Tried the usual clean installs etc, no good. Phone powers up again fine straight away, but really annoying. Reading this I'm not sure a replacement handset will be the answer for me.
  • KMpro Level 1 (0 points)
    3Gs 3.1.2 randomly powered off twice in the last two days. Thought it was just a freak thing, but then twice. Phone seems to be stuck at the apple logo, and it's been about 20min since it just petered out... Okay. It just vibed twice. Now it's on. ***, Apple. I can't recommend this stuff to anyone, and I've heard some really bad stuff about the new iMac displays which has kinda deterred me from buying one until it's all sorted out. What happened to "it just works"? There needs to be a fix out yesterday, or a downgrade option at least...

    Update: Here's a possible explanation: I was ready to exchange my iPhone 3GS for a new one after random shutdowns. Got it all ready to take back, removed the lightweight clip on case and screen protector I'd added - hey presto no problems since...Could it have been the case making the unit overheat? It hasn't shutdown since (18hrs) after doing it regularly. And now I come to think about it, it didn't start the random shutdown thing until I added the case.
