The iPhone 5 uses Cellular Data over WiFi?

I feel your pain, I got mine on the 1st, and by the 5th I Had "used" over 3.5GB my data also seems to be used through the night, except mine are in the range of 35mb to 1.5 gb almos every night. For the last few nights I've been watching my usage through the night and every 10-15 minutes its using about 15-200kb of data on cellular, and about 1-2mb on wifi. I'm calling apple back today to see if I get anything new, if not, the phone is going back. Thankfully I still have my 4s and can go back to that if need be.

I woke up at 830 for work yesterday.

http://i49.tinypic.com/30rxlkp.jpg at one point it didn't use wifi and all and just sent a bunch of data over cellular. I have 2 wireless N routers in my place with 100mb line, so clearly the phone isn't pickin up the slack on cellular.

I have my gmail accts set up as exchange accts on my phone, I wonder if I should try changing them back to regular gmail accts.

Exchange and iCloud Push use cellular data for the push notification.

Even with wifi up and running? I disabled iCloud email push because I don't know why it thinks my iCloud gets its own email? Maybe it does and I just don't use it. But my iCloud acct name is my gmail email address and when I was in my inbox I can go to iCloud and nothing is in there. So I disabled email. http://i50.tinypic.com/11v2srd.jpg

I have "use cellular data" turned off in icloud documents also.

Delete icloud altogether. My phone has only used 637 Kb of cellular data in 24 hours. I was out in the field for good 4 hours, and both 3G and LTE were on. I have two emails. One is gmail that fetch emails every hour, and my work email is configured as exchane and set to push

When I fixed my problem (see earlier post), one of the things I did was turn turn off all aspects of iCloud: Safari, Contacts, Docs and Data, etc.

I did not remove the iCloud account, just turned off each service. When I turned them all back on, the data usage stayed normal.

So tonight is the first time when Wifi is on, cellular stop ticking. Things I did today was to remove most apps from the notification center and adding them back on. I'm still skeptical. I almost return my iPhone to ATT today. I think I'll give it for a few days.

I've suspected that this is some sort of notification-based bug because there are good reasons to always route them through cellular even when you are within a Wifi covered area. You'd have to leave the Wifi radio on all the time (draining battery) in order for the push server to know how to locate the phone.

I'm not sure if anybody noticed this yet, but refreshing email pulls more from cellular than wifi it seems.

After 5 refreshes one after another.... http://i49.tinypic.com/dxck2e.jpg

And that's after uploading the 2 pictures to tiny pic, so clearly not everything is leaking the data to cellular, so it needs to be something specific.

I'm experiencing the same issue here in Australia.

My service provider wants to charge me an extra $600 for additional data usage (when I have never gone over my cap in the past). They won't drop the charge.

Apple please release a statement so this can be resolved immediately!

THIS OCCURS ON IPAD AS WELL and It only occurs with specific apps, and it is NOT CONFINED TO IOS6.

I have iPad3 running 5.1.1. The mysterious switch from Wifi to LTE/Cellular occurred in my case only when watching video streaming using the NFL RePlay app. Full 30 GB AT&T Data Plan was eaten up until I got the providor low data warning message (you are down to 10% of your data plan). This happened twice, and it was app specific. So it may be that certain apps have a predispostition to the bug, especially if wifi were to get clogged or slow down, perhaps Apple bug has device automatically jump/switching to the faster feed, which is 4G.

Just about to think the issue is solved, the cellular starts ticking again. I don't know which notification app that I added back might have caused this and I don't have time to debug either. I almost return my phone today. Now would be tomorrow.

Please challenge your Telco, take it up the authority chain as far as you need to get a refund, and a resolution.

They know what is going on... You need to make sure you get to talk to the right person.

My Telco in Australia, Telstra, is very much aware of the issue.

During a recent visit to their Store in Subiaco, WA, their senior technician fully understood the issues, and told me that Telstra, and other Australian Telcos, were working with Apple to analyze and develop a solution.

But that said, the first person I spoke to [a nice lady] was not aware, told me I was the first person she had talked to that had mentioned the problem. To her credit, when I persisted, she directed me to their technical expert on iPhone 5.

I gave him a copy of this guide: https://discussions.apple.com/thread/4348072?start=285&tstart=0

He was obviously very familiar with all key steps. He said it applied to iOS 6, on iPad too.

So was Apple Store in Perth. A few days after delivery of my iPhone 5, dropped in to discuss this issue, and the very knowledgeable staff worked thru the key settings on my iPhone 5, explaining to me what each setting was about, and seeking my consent [do you really need that service?] before turning the option Off.

In the mean time, I suggest you work you way thru the recommendations, from the top down.

It is hard to say which setting worked for me, but I did catch the offending App before I got burned.

Since working thru the settings, as per the recommendations...

I have been monitoring Cellular Data Usage. Usage is consistantly down in the kB range now.

My WiFi runs to MB... LTE and Cellular Data have On in parrallel the whole time, I have not once in the past week, turn Cellular Data Off.

Here as a snapshot from DataWiz. Since the begining of my new billing period, DataWiz, Quota Local Data Usage, Telstra Mobile Usage, and iPhone [Settings, Usage, Cellular Usage] are reporitng close to the same data. On WiFi most of the time during these few days...

Note the background pings, typically 422 byte, several times an hour on LTE, occassional approx 30kB in, 6kB out transactions.

So...

Stable operation now, fairly much as it should have been out of the box, obviously some default settings [Push, etc] were the issue.

As I say, I do not know quite which Apps or Services were offending.

Hard to say whether the settings were carried over durng the Reset from iPhone 4S

Robert...

I zeroed out my data usage the night before last. Yesterday I began a cross-country train trip, from New Orleans to Los Angeles, during which I had limited to no cellular access. During those times I did have access my usage was unchanged from typical; email, text IMs, and web. I did not use the phone at all overnight and for a significant portion of today. Nevertheless, I am showing 511 MB of usage, which is absurd. I am convinced that the data usage bug exists for AT&T users like me.
