    I'm not a heavy user and the iphone 4 usually goes to the charger at night with about 80% remaining on the battery.

    Yesterday afternoon I felt a vibration around 5pm and the phone indicated low battery warning of about 20%. This has never happened.

    The phone is less than 2 years old. Is the battery going out?

    You can try a restore and set it up as new.

    What do your battery stats say? (Settings > General > Usage > Standby and Usage times)

    It's easy to replace an iPhone 4 battery. Buy one off eBay and go to ifixit for a replacement guide. Check other things first tho, ensure email push etc is working ok. My battery was draining really rapidly until I realised the email had incorrect settings and it was continually trying to send emails. Those usage stats are pretty low....

    What percentage are you at right now?

    ----------

    Wouldn't suggest you do that unless you really know what you're doing. You could screw things up and Apple can refuse to help you.

    92% - it all looks normal so far today. It was such a surprise yesterday as that has never happened before...

    Thanks for the advise about replacing the battery; however, my eyes are not good enough on stuff that small anymore. :(

    It sounds about average right now. I'm not sure what happened before, but if it does that more often, head over to Apple.

    I consider myself fairly cackhanded and I recently replaced the main board on my iPhone 4. Important to note was I'm well out of warranty tho and had very little to lose. Battery involves 3 screws tho so fairly simple and there are NO warranty stickers involved

    Sometimes the battery goes a little wacky...

    just run it down to 0% and recharge it back to max.

    See what happens from there.

    You should try and do this every month. I had the same problem with my 4. I charged it every night and wasn't taking it down to nothing. After I had this problem (about 8 months ago) I read up that you should do this. Now it's been fine ever since.
