    Yesterday, I found that going from 100% to 99% took around 3 hours.  Then from 99% to around 80% took another 7 hours.  (That was after resetting all the settings)


    This morning, 100% to 99% happened much sooner.

    I decided not to worry about it.  After that, I turned off the Battery Percentage indicator, as I have other things in life to worry about.  No sense in getting preoccupied whenever I turned bluetooth on, or actually used my phone to browse the web.  And, I'll just charge it at the end of the day.

    Thanks Davidch!


    Device: iPhone 4s AT&T 32GB


    I had decent 'battery' life before compared to others, got 7 hours of very light usage (mostly iPod and some mail) and 1 day standby and had about 7% left. Having owned a 3GS, I could go 2 days of heavy usage without charging so this was a significant drop with the iPhone 4s. Even worse, overnight I would lose 20% as oppose to 3-5% max with my iPhone 3gs. At the risk of jinxing it, I decided to go do the 5.0.1 update using your advice despite all the warnings from other users. So far I had 88% at the update around 10AM and have 50% left at 4:00PM after extensive use of iPod, emails, surfing, and using the camera. I think this is great. I will update again when I charge the phone and see how the battery acts overnight.


    Here are some notes:

    -After the restore as a new iPhone my iPhone couldn't find the network, so I went ahead and reset just the network settings, after that it was fine.

    -The itunes update wouldn't work on my phone, says my device wasn't eligible or something but the OTA did work.

    -Before the update I did cycle my battery twice which I think helps.

    -I only turn on 3g when I need it, turn off location services for most apps.


    Hope this helps.

    What do you suggest that I do now? I've reset and fully drained and rechaged my battery... still no changes at all with the battery. Do I need to do a full restore? I really hope not.

    Should I do the reset and discharge again? It'll be the 3rd time.

    After 5.01 I have gained average of 10% battery life for the day with no resets.
