I have an update of sorts, I am so disturbed by this issue that I haven't been enjoying my phone as much as I did when it just worked, all of it, not the mostly-disabled-everything that I've crippled it to be now. Like I did when I had the iPhone 4 and then the 4S, merrily enjoying everything always, never coming CLOSE to my data limit. Never to be told that it is MY fault. That it is MY responsiblity to turn off all the "background" things that are suddenly sucking the marrow from my previously fine 200MB/month plan with AT&T.
Erase, Restore, Disable, constantly monitor data usage, post on forums hoping Apple or AT&T will at LEAST acknowledge that a fair number of us are aware of this and are having serious issues with it.
While I realize I never noticed data draining things that DID exist before, but now I find out that syncing iBooks bookmarks ***** 125K or more each and every time you switch from that app to any other.
125K to sync the ONE book I have open currently?
Is this true for everyone? Was it that high in IOS 5? Does it update all 600 books? Or just 200 I may have opened since downloading them? If it does, then there SHOULD be an option to sync only the currently open book, surely that isn't going to suck 124K of my cell data.
Olli66 made a very interesting comment about a setting in a beta version of ios6 "Wfi plus Cellular" that is no longer present BUT may have been left on. If you have spotty wifi and a big data plan, this would be desirable to smooth and enhance performance. The carriers would probably be ok with it too if their network performance is occasionally an issue. No doubt about it, 4g LTE is delightfully fast. It also means data leaks to cellular can chew up data very quickly. I would say, put the switch back so the user can manage it. It appears that the default iOS 6 settings are all set to enable cellular usage, so lots of things need to be examined for leakage until this is fixed.
In the meantime, the things I have done that seem to have helped:
Reset the network connection. This was done for me at the apple store. This seemed to be a biggie. Just be sure you have saved your various wifi passwords to log in again.
Turn off cellular for data when not needed. However, this may not be entirely successful, as there are other settings that seemingly may leak:
iCloud backup. Turn it off unless you need to do one now. Documents & Data has a use cellular data switch you can switch off.
Privacy, Location Services. Make sure only the apps you consider critical are switched on. System Services (scroll down). I switched them all off. Traffic is probably a hog.
Notification Center. What apps do you really need real time?
About. (Scroll down). Advertising. Limit ad tracking ON. Diagnostics and Usage - Don't Send!
Also, for heavy data transmissions on wifi, switch to Airplane mode and go back and switch wifi back on while in progress.
If none of that works on your iphone 5, take the phone back for an exchange. It may be defective.
Best of luck!
An excellent summary, thank you...
I ran thru to check all my settings against your list, and found I had, over time, turned most Off.
There were some others I had missed.
It is a bit daunting, I must agree.
My initial pass thru was guided by a very helpful Apple Shop employee in Perth.
Not at the Genius Bar, but maybe was one, since he certainly knew how to set up an iPhone to minimise Cellular Data Usage. I talked casually with him about the sudden jump in Cellular Data usage on iPhone 5 versus 4S, and he quickly worked thru most of these settings, and with my approval, turned stuff off as we went.
May I suggest you consolidate into a TextEdit document, and post that to this forum, so users can down load, print, and use it to optimse their setup.
My conclusion from this discussion is that this is an iOS 6 issue, and will effect iPhone 4S, 4, and iPad 3G users equally.
OS 6 and iPhone 5 Users...
I have consolidated David, Olli, and my own recommendations on how to Optimise Cellular Data Usage on the iPhone 5 and iOS 6 devices in the attached document. You might like to save a copy, use it, monitor performance , and of course, and share it with friends...
My apologies, I cannot find a way to upload a pdf document.

But this whole thing is stupid. On my iPhone 4 I was jailbroken and had 3G Unrestrictor installed and set to allow ALL data over 3G. So all apps had access to my 3G data ALL the time (when not on wifi). I never even went over 1GB in a month! On one day last week my iPhone 5 ate 1.3GB of data!!!
There is something wrong. Even over wifi there are reports of the iPhone using excessive data, so it does not appear to be restricted to cellular data. For most people that is not a problem because they have large or unlimited home broadband ADSL/cable plans. But we really notice it on cellular data because that can become very expensive. An extra GB with my Australian carrier would cost $1000!!!
I don't understand why Apple has not released an urgent press statement and iOS update, yet. This could cost some people a LOT of money. Imagine those people who do not check their data (don't usually need to) and don't get involved in forums, etc. They are going to be in for a BIG shock!
What's being insinuated here is stupid though.
Yes, there's a responsibility to monitor your data usage within reasonable expectation, but I shouldn't have to change my connectivity habits to babysit software that doesn't run correctly.
As I saw pointed out in another forum, this high data usage being reported is not widespread, nor is it happening to everyone, but it's happening and Apple needs to at least identify that it's occuring and let them tell us what we need to do to resolve the issue while waiting for a patch.
If Apple were to at least acknowledge the issue and offer a suggestion until a fix can be sent, we at least get something that identifies that there was a fault.
Neither Apple nor any of the carriers are going to be safe from any class actions that come about of unrelieved overages on bills, so at least the carriers are doing their part to cover their ***** by refunding people.
In the meantime, the suggested "fixes" are only reasonable if you haven't gone over or you haven't been throttled like I have, and only reasonable if you have an expected user who wants to constantly spend time twiddling with settings whenever you move around during the day. I don't do this and neither do other people. What works for you isn't a feasible option for me.
What is a feasible option, is that I'm returning my 5 today since I still am inside my return window and go get a refund. I will switch back to my old iPhone 4. I am aggravated and dispirited over this whole situation. I've wanted LTE level speeds for over a decade on a mobile device, I finally get it in a form factor I like and it's poorly constructed and the best advice is to turn it off for now.
Considering that I'm sitting on the verge of having to pony up a $325 fee to tell AT&T "thanks but no thanks", I know when to cut my losses while Apple is sorting this mess out. Allowing Apple, AT&T or any one else who's dealing with heavy data usage reporting right now is an expensive habit to keep and a poor option in the face of a product less than 30 days old. All of you have the legal right to return your phones rather than face the ETF. When Apple addresses this issue, I will go back and then get a new phone, probably switching to Sprint in the process just to cover my butt.
Shame on Apple for not testing this adequately before shipping.
Their reknown for secrecy has clearly come at a cost of decreased product quality for this product.
For me the best way is to end my AT&T account, as it has expired. My 4 has been sending cellular data while on wifi since i went to os6. Although I am on unlimited it will get throttled also. Why pay for something when I have to shut it off when I am around wifi? I was about to leave AT&T as I get horrible service at home and go on my wife's Verizon account. However, I would get 2 gb, something I have never gone over in the 5 yrs I have used iPhones, and risk going over it.
Thinking on using my iPhone 4 as an iPod and go with a Pay as you go cell phone. At least till I am sure this mess is over. I dont travel enough to make the cellular usage worth it anyway.
Ajservo1, I share your frustration. This issue, along with the crippling of the iTunes music song-level functionality and the forced migration of podcasts to a crippled Podcast app functionality, have shaken my allegiance to apple. And, we're not allowed to go back to ios5 once we have "upgraded" to ios6.
The reason I left Microsoft windows for OSX many moons ago was having to constantly "pop the hood" to tune the software and operating system. Tight vertical integration of hardware and software has until now been a boon in terms of avoiding this issue, and I'm not sure Android is yet a superior alternative.
However, apple is in real danger of repeating the mistakes IBM made trying to do the same with OS/2, which cost them the whole desktop ball game. Apple: don't mold or limit your software to your desired or expected user behavior, to further your corporate objectives. Listen to your users. Let me use your appliance as suits me, without penalty. I am not an iSheep.
David I agree with you whole heartedly. We obviously go back to the same time (pre ibm and ibm jr.). I am hopeful this is just growing pains.
Apple's silence on product is totally understanding. Their silence on these kind of issues only hurt their dedicated and loyal customers. Consequently hurting themselves.
Anyone sitting in Apple (or appointed or self/appointed defenders) should look back at the GIANT IBM. They lost site of their customer base. Windows suffers currently that way also. Hopefully it will not happen to Apple.
I no longer blindly defend Apple after their iPhone 4 antenna debacle (which I own and suffer with). I am hopeful this situation will be TOTALLY fixed and not just a "free case" type fix.
Just got a callback from someone at AT&T after i posted an IM to a support rep on the support pages in a thread about this issue. Their official word? Not enough customers have complained about this issue, so it is not an issue as far as they are concerned. They will happily credit any disputed data you say is happening while on wifi. Yeah. Great. Burden's on me again. I explained I have crippled almost every conceivable data sucker and am purposely not using my data to try to crack what is happening, so I probably won't go over. I said that right before she called, I could see data coming off the phone while in wifi. And data coming off while the phone was sleeping in my pocket during my commute with all apps force quit. Nothing but silence from the other end.
My wife is on a iPhone 4S and no longer cares, she just wants to use her phone without worrying about data. THIS is why AT&T will win. Most people will just sigh and go to a higher data plan.
