I'd love to know how you did it. I have the same problem. My one and only question though is did it cost any money, and if so how much? But, nonetheless, I want to fix my phone haveing the 5 hr 55 min usage and 6 hr 01 min standby stats. Thanks
When you try to force power down your phone does it come back on? Hold the home and power button until the screen turns black. If it comes back on then its most likely your dock connector. It cost me 35 bucks and I replaced my battery with a $10 dollar one while I was at it.
I used the instructions at Ifixit.com.

Nov 29, 2012 2:22 PMby zman37,Looks like I spoke too soon re battery maintenance fixing all my issues....looked good for firs few hours, but got worse over the day and today, despite doing another trickle charge earlier in be morning, it's dropping fast again. :(
Looks like just have to wait til Apple sort it out.
There's definitely a bug too with screen brightness slider being randomly changed without me touching it! (Where's the place to report bugs??)

I tried downloading a bunch of tutorials and was on good strong wifi for hours and they did not download apparently.
I went out and went through half my battery and got a text message 8GB, practically my whole shared plan got used up within 2 hours, and phone went hot.
iTunes U has a very poor interface with no clear "pending download" section, so you don't even know your stuff was waiting for cell data to download like mad...

Nov 29, 2012 6:48 PMby netsoup,For what it's worth, I really think iTunes U is a serious culprit, but cell carrier says I just went through 8 GB and my phone is only showing about 2GB used in the same period.
iTunes U is the only app I used that doesn't let you restrict to wifi, other than safari in the past 2 hours, and I know I didn't browse 8 GB worth... I think iTunes's u has a serious bug burning through battery and cell data, and has no control of cell usage.
I did try to download some video tutorials hours ago while on wifi and I see they're going now and the phone's still hot though I "closed" it and every other app.
Gotta completely turn data off now...

Nov 29, 2012 7:01 PMby Incamera,I have found that the biggest drains on battery life are cellular data
and Ask to Join Network (wifi). If ask to join is kept on, wifi will be continuously
searching for a network even when you are not using the phone
for internet purposes. Turning off cellular data when you don't need to
check email or other notifications will save a lot of battery life.

Nov 29, 2012 7:25 PMby netsoup,I think the battery drains are largely related to unauthorized or poorly managed cell data usage too.
Cell loads tend to make things hot too.
Is there any way to control iTunes U cell usage?
I don't know why, maybe it's time of say, but I seem to have downloads that wouldn't download when I was on solid wifi for hours and now I can only turn cell data on for short but meats or iTunes U is burning through my cell data and battery.
iTunes U has super poor download management too so it is a huge pain to try to find out what's downloading and turn them all off as they move around. Unlike apples other programs there seems no way to restrict its cell usage except to turn cell data completely off, and the weirdest thing is I'm getting texts from carriers on the data usage and the phone doesn't show it under cell usage, but based on what I am seeing and feeling the phone go hot I KNOw iTunes U is hogging my 4g data and battery all of a sudden, though it was not downloading when I was on good wifi for hours.
