    Has anyone experienced the battery indicator on the iPhone 3G S display a low percentage left on the battery and then suddenly jump to a higher percentage left on the battery?

    For example, battery indicator shows 20% battery life remaining, then after continued use, using iTunes, checking email, the indicator jumps to 86%.

    Thanks, Dave

    There is a thread about this issue elsewhere on here. From what I remember, you might need to do a restore or take it back to the store.

    This happened to me with my phone. After a complete restore the phone continued to do the same thing. I called apple care who made an appointment for me at a local Apple store where they swapped it out.

    This happened to me about two days after I received my iPhone. I got the 20% warning after barely using it. And then it jumped back up to 79% 3 minutes later. This problem only occurred once, so I didn't do anything. However, if it ever happens again, I'll be calling Apple in a heartbeat.

    I had this same issue, as well. I advised the Genius that the battery life was fluctuating between full charge and no charge. The phone was also shutting off, then coming back on with almost full charge.

    The Genius ran a diagnostic check on the phone and was able to see the previous charge cycle. He confirmed the sporadic activity and swapped the phone.

    The other day my battery indicator wouldn't change at all. Eventually my phone shutoff without warning. I'm guessing this is a 3.1b2 issue since this is the first time I've encountered the problem. I can't be certain of that though.

    I just remembered that my neighbor was have the same issue with his battery showing it was charged and then it would go from 100% to 77% in a matter of seconds, so I can only imagine that it's a very common set of issues.....:(:(:(

    The battery indicator isn't reading the battery charge correctly. This is most likely a software issue, but apple geniuses can see the charge cycles on their checks though.

    What I am trying now is compleatly unloading and than reloading the iPhone. If that does not fix the problem I don't know what to do. I really do not want to have my iPhone exchanged since it's otherwise near perfect and the refurb ones they give you are often not that great.

    Is there a timeframe for getting a refurb vs a brand new phone if you bring in a defective one? I'm starting to have these battery fluctuation issues on my 1 month old 3GS and I really don't want a used phone in return!

    A month is probably the limit but no guarantee. No one could tell you for sure. If you had returned it in the first week or so, you'd probaby be golden.
    There's nothing wrong with getting a refurb.
