    Just experienced this myself and the other issue is that the iPhone gets very hot like it is in a runaway cycle system. I had this issue with my first iPhone and they replaced it on the spot in an Apple store. Have just done a restore and now doing a Reset to see what happens.

    Might have to let it run down, do a reset, fully charge then if that doesn't work then off back to the Genius Bar again.

    Agree with the above posters that 2.2.1 has had a deleterious effect. Will check temps and processor speed with iStat when its back to happy.

    Cheers HyperbaricDoc

    If you haven't already checked, make sure that Location Services and bluetooth are set to off. The new update seems to change these settings.

    I, too, have seen an increase in battery drainage since the 2.2.1 update. I used to be able to go 1-2 days without recharging, now it's HALF a day and the phone runs super hot.

    I've run the battery down to 0% a couple of times now, so it's not the physical battery. I've powered down and back up a number of times (hold down power/home and slide to power off), and that didn't help. Trying the reboot (hold down power/home, ignore the slide while still holding, phone goes off) technique now, I'll post back here about the success or failure of that trick.

    Please check my actions/terms: is the above the right way to turn off and reboot the phone? If anyone knows how to restore to a prior backup, can you point me in the right direction?

    Funny for me, two weeks after updating to 2.2.1, the phone started freezing. And would take long long periods of time to boot any app. So today I restored to a fresh copy of 2.2.1, restored my original settings and content and the phone appeared fine.

    4 hours of idling after the restore, I'm down to approximately 75% battery from 100%. Have just initiated "Reset all settings" under the iphone menu, will charge the phone to 100% and see what happens this time. I'm hoping it was just a small corrupt setting that was saved.

    We'll see...
