    Hi all,

    I have bought an iPhone 3G a little over a week ago and just recently the battery has died on me without any notice (in fact the battery indicator had shown a full battery). This happened to me last night while I was playing a game... it looked like I had a full battery (which I thought was a little strange given how long I'd been playing for) and then all of a sudden the battery is dead, no notice or anything. Has anyone else had this problem? Is there something wrong with my phone? :confused:

    Thanks everyone!

    I've been having a similar problem. Happened first about 3-4 weeks ago, was out in London where GPS was proving very useful and listing to music. Put it away for a while, next time i look the 'connect to power supply' icon is showing. I didn't get a 20% or 10% battery warning. Didnt have another problem for a few weeks but increasingly over the last 2 weeks it will suddenly show the icon when I know its got loads of battery left. Sometimes within a few mins of a full charge. Plugging it in to a power supply for a few seconds will sometimes get rid of the screen and it will all of a sudden be back with full battery, sometimes it randomly decides on its own that it now has power agin.

    Is this a hardware problem, do I need to replace it?
    Thanks for any advice

    Since getting your iPhone have you charged the battery to 100%, drained it completely, and charged it back to 100%?

    If this persists, you may need to contact Apple since your iPhone is not displaying the correct battery info.

    I haven't done this. Is this necessary? I thought this wasn't something that needed to be done anymore.

    Thanks!

    Apple recommends cycling the battery once a month.

    Thanks for the info. I will definitely start doing that once a month. As far as my issue goes, I turned the phone off and back on and the battery indicator seems to be working normally again... at least for now.
