I did 3 iphone resets since upgarding to iOS6, and turned off all of suggested items, and still no change to the battery drain. It worked well after the initial upgrade, and this started happening after 10 days. It works OK after each reset for about 1-2 days, and than the drain starts again. This happened only after upgrading to iOS6, so I am recommending everybody around me not to upgrade. (except a few friends that upgraded like me, and have exactly the same issues) So dissapointed by Apple for not looking into this promptly, we should be able to trust them when the new operating system is out. I am carying a charger everywhere with me now, I'm using the phone for business as well, and not being able to realy on it anymore is frustrating.

Hi all, I have had a 4s 64Gb for around a year now and battery has been good, with reasonably moderate to heavy use during the day (though I only switch on BT and wi-fi when I need it).
Anyway I upgraded to iOS6 and all was OK (leaving aside the various functionality gripes widely reported). However in few days battery started draining like crazy for no particular reason, including dying completely the other day.
After scratching around I found out about the Apple iPhone config utility and took a look at the logs it creates, what I did notice was the "[com.apple.persistentconnection[dataaccessd,83]] is telling PDP context 0 to go active." message appearing approximately every 3 seconds, even when the phone should be idle.
I turned off push email after reading a few posts and it disappeared, this stopped these log messages immediately. After also following some useful tips posted elsewhere about switching off various ad tracking services buried away in the settings, I also deleted my Exchange push email profile that I have for work.
I then immediately added it back in again and these message appeared a couple of times (obviously where it was polling the server), but were no longer appearing one after the other, again and again.
It would appear my Exchange email profile had got corrupted and was causing this continous comms check which was draining the battery and making the phone get hot. Deleting the profile and adding it in again seems to have fixed it, so fingers crossed I'll be back to my usual of battery life (BTW before this problem occured I could go up to in the region of 2 days without the battery dying).

For me push email was the problem. I too deleted my email accounts (pop & imap) and set then up again but not using Exchange. Now use fetch email every 30 secs. It has worked for me.

Yes, you should always update to the newest IOS.
Sure about that?
I didnot read anything about the batterydrain. Should I update or not ?
After the mess 6.0 created, I suggest you HOLD OFF for a day or two to see what the verdict is on 6.0.1. Especially if you are currently on 5.1.1
I am still on 5.1.1. Monitoring the 6.0.1 threads on multiple forums, I'll decide if I am willing to chance an update to 6. I refuse to sacrifice battery time, functionality and $$$ over excessive data usage resulting from another botched 6.x release. The verdict is out for now.

I had previously posted the same experience. After finding that Exchange Push was my battery-drain culprit, I restored the account as push and it immediately started to drain fast again. I now have my Exchange account using Fetch instead. Since then, I have no battery issues whatsoever. I'm using Safari, tethering, bluetooth... you name it, with no out-of-the-ordinary consumption. I'm not turning cellular data off any more.
I noted then that the iCloud account also uses Push, but it's not giving me any trouble.

Good point and probably decent advice. However for users already having issues its better to go ahead and update. I can tell you iOS6 was hands down the best for me as far as battery life. Better with iOS 6 on a 1 yr old battery than it was out of the box new with iOS5. 5.0.1 helped, 5.1 was better then 5.1.1 was about the same. 6 made substantial increase. Anyway good advice for otherwise working devices to see what happens to hold off a week or so but these forums are NOT the place to make your final decision. Remember 99% who come here do so because of issues and are looking for help. So with millions of devices out there the handful here having problems (in the grand scheme) should not make your decision whether to upgrade or not but certainly gives you some information of potential issues/problems.
