    Thanks for the link to the blog. Actually, that Exchange issue has been known since the first version to support Exchange (2.x) in the fall of 2007. And it has been posted frequently in blogs, non-Apple support forums, these forums, and even multiple times in this thread, although finding it here is a challenge with 137 pages of messages.

     

    And there's a workaround for it: In Settings, turn off all of the Exchange account switches, reboot the phone, then turn them back on. This terminates all of the stale connections between the Exchange server and the iPhone. The problem will occur with ANY activesync device, BTW, not just the iPhone. It won't happen with BlackBerries, because they don't connect directly to the Exchange server; BBs get mail through a proxy server hosted by RIM, or, for large companies, by the company data center. But it will happen with Windows phones and Android devices.

     

    The reason it uses cellular data even in the presence of WiFi is that Push notifications always go over Cellular. After the notification is received if there is a WiFi connection the update is transferred over WiFi.

    Lawrence, yes, I'm sure I could have found allllll of those links you graciously provided but frankly I'm exhausted of looking for them, performing workarounds, troubleshooting in general, spending hours online searching for answers and conversing in groups with people who aren't always pleasant. I just want to get what I paid for. A phone that works as advertised with the people I pay to create and administer to it doing the job I paid them to do. I'd rather be spending my time enjoying my family in person or through the features of this phone. I've already been here far longer than I care to be. If this is what I wanted to do I would be studying for an IT position with a minor in politics.  Wouldn't you just like your phone to do what it was promised when they sold it to you and have a life beyond this time suck? 18,835 points? Seriously?

    I had the same problem.  It was not with Apple.  Once I learned to turn off all apps working in the background two or three times a day, the problem persisted.  Then I started with my carrier.  Here is my advice:  go to your carrier's website, look for their privacy statement and more specifically, their "opt out" on advertising data mining.  It can be done--it just takes some web site searching.  Opt out.  Dropped my data by 75%, since I did not use much to start with--I had a limited data plan that starting jumping up and up and up.  This solved the problem.

    Brilliant find!! 

     

    About a week ago, prior to the new phones being introduced, I took advantage of a Walmart sale of the iPhone5 for $98.  My monthly contract ends on the 9th of the month and I usually reset that morning.  With the new phone my data usage was zero to begin with.  My average monthly usage is anywhere between 15 and 25mb (retired, rarely away from a WiFi source unless traveling) but 4 days after resetting the statistics, I found I had already used 4mb up/8mb down.  I had gone through this "phantom data usage" a couple years ago (go back to page 83 or so of this thread to see previous entries) so I thought I'd give this a try. 

     

    In order to opt out of this advertising, go to http://adworks.att.com/mobileoptout/ on your mobile device BUT turn off your WiFi before you do or do it in a non-WiFi area.  It only takes a minute at most.  Will keep an eye on it and see how it turns out.  I did a screen shot of my usage just after opting out so I will have a record to refer to later in the month.

     

    Thanks again Newport Nana!

    If you read the announcement that went along with this, you are only opting out of advertising based on your profile. You don't get any less advertising; just no targetted advertising.

    Have there been any new observations since IOS7 was released?

     

    In my case, I have an old IPhone 4 and have not been having issues with large data transfers. However, my son has the IPhone 5 (original one) and has been seeing large data issues since June this year. So far, upgrading to IOS 7 doesn't seem to have helped him.

    While I can't say if iOS has fixed any problem with data usage (since I never had data usage that I couldn't trace to something), I will point out that iOS 7 has made it much easier to detect any "leaky"/rogue/greedy apps. Under Settings > Cellular, you now get a display of how much cellular data each app has used since the counter was reset, including system services like push notifications. (Finally people can see just how little data push notifications really use!)

     

    This should be very helpful to anyone trying to audit their wireless data usage.

    I don't know if it means anything, but since I upgraded two iPhones on my account to 300 meg/month data, the charges have gone away.  I keep checking, though.  Of course I have trained my wife, and her sister to always plug in their phones to charge overnight, but I sometimes forget to plug in mine.  I have an unlimited data account, so it doesn't matter, I guess, but I haven't seen it on my account either.

    If folks here are not aware, with iOS7, Apple has provided the means to see how much data each app is communicating.  If you have iOS 7 installed, go to Settings / Cellular and scroll down to see usage by app.

     

    Out of a family with 5 iPhones, one of them has historically given us a fit on data usage, going over the subscribed limit each month despite every attempt I've made to isolate the apps, turn various settings on / off as suggested on the 136+ pages of this thread.

     

    When iOS7 was installed, I noticed this phone had sent well over 200MB of data over Safari in only a few days.    WOW!   The phone is on WiFi 90% of the time during the day / evening.  And "human use" of Safari had been light.

     

    I did some surfing on the web and found various topics discussed around Safari bookmarks, corrupted bookmark files, and how if iCloud is turned on with Safari this can cause a constant back and forth of data exchanges if there is any corruption in the bookmarks.   I checked out the bookmarks visually and did not see anything abnormal, but did go ahead and turn off Safari in iCloud settings.   Since then, data usage has dropped to a more normal range of kilobytes and NOT hundreds of megabytes.

     

    If anyone has any thoughts on Safari chewing up huge amounts of bandwidth -- potentially as related to iCloud synching, please share.  And please don't post comments about not understanding how much the phone was downloading, content, etc. etc.... already been well down that path in the investigation.  Something odd has been going on with Safari.

     

    So far so good since the setting change.   Fingers crossed......I also upgraded the data plan slightly on this phone from the 200MB (or so) to the 300MB (or so).  Still also not convinced that something was not set right on AT&T data plans and accounting of data, but no way to prove that.  .....

    The phone is only "on" WiFi when the phone is in use or when it is plugged in. WiFi is disabled when the phone is asleep to preserve battery life. So when asleep and unplugged the phone will switch to cellular data for any background data transfers.

     

    I just tested this with iOS 7 using a ping test. WiFi goes off 45 seconds after the phone goes to sleep. It goes back on about 5 seconds after connecting it to power.

    An update -- after a full week of using this iPhone 5s with iOS 7.1, and having Safari turned OFF on iCloud, the data usage on this problem account has dropped dramatically, and I can honestly say we may be getting back to a normal data usage pattern on this device.

     

    As background reading, this is the blog that led me to question if I might be dealing with corrupted bookmarks, that if being synched with iCloud could cause "thrashing" and continuous data usage.   http://tidbits.com/article/13303

     

    Absolutely fishing here, but it's the first thing we've changed that seems to make a difference on this phone.

     

    Hope this is the beginning of stopping the nagging problem on one of our iPhones.......

    I've had this going on for a while as well.

    I used to get huge data transfers in the middle of the night, usually midnight to 4am range - Has anyone in this thread figured out what this data actually is?

    I started turning off my cellular data before going to bed, which stopped those transfers but they have just moved to whatever time of day I turn my cellular data on.

    If the subway goes above ground and I want to check work email while on the way in, I get a 10+MB data hit then, which I think is way larger than 2-3 emails from an exchange server should be. Same in the evening on the way home.

     

    Whatever this data is, it doesnt send when I;m on WiFi before leaving my house.

     

    I've been using the DataMan app to track my usage by app and location and I can see that this is the case based on location. In addition, the DataMan app reset my usuage when I switched to iOS7 so I only have 21 days of data on there, showing <100MB used but AT&T says it is over 300MB. Sorry, but No.

     

    If anyone has additional input or advice I would appreciate it.

    Also, I do not mean to bump an aging post but at the top of the post it says this thread has branched into a new discussion but it says I am not authorized to view that.
