    As soon as I restart my iphone, it shows the battery level to be 13%.

    And then it instantaneously jumps to 33% in a flash.

    What's going on?

    This is a replacement iphone which I got on Monday. Any help will be much appreciated.

    Have you installed 3.1.3? It is supposed to resolve this issue.

    I would suggest restoring to factory settings, and then avoid restoring from a backup, if you can. Try just simply restoring, then setting it up as a new phone, then just re-syncing all of your data on there.

    This issue is obviously a software related issue, and presumably every time you restore from a previous backup you're just passing along whatever it is that is generating these results.

    Thank you so much for the quick replies.

    I'm still experiencing the same problem after erasing all data and settings.

    I'm sorry to hear that you're experiencing the same problem.

    Are you running 3.1.3 too?

    I'm curious as to whether it'll display -22% when I'm at 11% :p

    Well, I really only have one idea left. After doing a fresh restore/setting it up as a new phone, re-sync all your data (not from a backup, basically what I said in my last post), then try calibrating the battery.

    It's a pretty simple process, basically drain the phone completely, and then continuously turn it on after it has died for the first time, it will take 3-4 times (of turning it on and it'll stay on for a few seconds) before it will no longer even turn on. Then plug it into a power supply, and leave it there (preferably un-used during this period, I'd suggest overnight) until fully charged.

    If none of that works, I would most definitely take it back.

    Brand new? Did you run a couple battery calibration cycles yet? If not, the battery gauge is just guessing since it doesn't know anything about the battery curve for your particular battery.

    Hello,

    I tried calibrating the battery, but something's wrong.

    I drained the battery fully and then the phone switch off on its own.

    Kept pressing the power button and the low battery indicator displays on screen.

    But it never seems to drain completely

    I've tried nearly 50 times to press the power button but the low battery indicator always appears.

    What should I do?

    I had this problem where the percentage would go up surprisingly fast, then it would drop a percent every 10 seconds...

    They replaced it at the Apple store. I would bring it back.

    This just happens to me at restart. Doesn't seem like it drops a percent every 10 seconds.

    I'm calibrating my phone now and will pay more attention to this.

    Same thing happened to me with the new firmware update.

    I think this update is buggy. It also has given me soem signal strength issues.

    3.1.3 sucks big time. My phone worked well before and now
    I have some serious issues with my battery as well, my phone died
    completely unexpected and it didn't restart until I connected the power
    and waited 20 minutes so it got some juice running...
