IOS 8 High Cellular Data Usage

I am encountering the same problem with my iPhone 4S!

Every application uses only few MB (including System Services), but I had already to pay for 7 (!!!) extra data bundles (2€ each).

I tried restarting the iPhone, closing all background apps but the problem is still not resolved! I have vodafone italy as provider.

Every kind of solution for this problem is welcome, because at least for me the update on iOS didn't remain "for free"!

Thanks,

Alex

Have the exact same issue.

Not using the phone and keep on getting notification that my cellular bundle has depleted.

Have reset the statistics to try and find the culprit app, but can't find anything.

The current period statistics at the top shows many cellular MBs used within moments of resetting the stats - even with the phone in standby. The usage stats only show cellular data usage for a select few apps and system services - but these are all for really small figures (18 KB, 43 KB, 11 KB, 11 KB and 110 KB for system services.) They do not add up to the total usage at all!

Cannot understand what is using the data?

I too am facing the same thing with my iPhone 5 16GB

I left the phone alone and connected to the wifi after upgrading to iOS 8 and two hour later I got an SMS from my provider that I have went through all 500MB of my data allocation!

The phone was idle! Checking through the Cellular Data Usage I saw that Document & Sync in System Services used up 350MB within the hour!

I disabled a lot of the apps Cellular Data options and disabled many iCloud stuff. I resetted Cellular Data Usage and then I purchased a further 500MB and left the phone idle again. When I went to check the phone after 15 minutes, Document & Sync has eaten up 35MB within that time span!

WHat THE HECK is GOING ON?!?

Mitton: have you tried iTunes restore / clean install ? Sometimes a corrupt OTA or backup file is to blame. Or there might be something wrong with your carrier updated settings (which they would have to release a new one).

my iPad is working fine with iOS 8. I did a clean install and had to put back all apps manually. But i am getting better battery life and no problems with Bluetooth, wifi or LTE signals.

I think the problem is with Settings>iCloud option. Depending on what options are turned on, I think it could be pushing a lot to the Cloud. Under iCloud Drive there is also an option to allow apps to store documents and data in the Cloud. I turned this off.

After upgrading to the new IOS8, I noticed that my data plan just skyrocketed, and started getting those annoying text messages from AT&T about how I was eating the data like crazy, it went from 600MB to 900MB like in 15 minutes, and of course that I was getting charge $20 for it. After my second attempt trying to get an answer from AT&T I was told that the new IOS8 will open the gates to all your data (GPS, service location, etc) and received some tips on how to prevent that, try these options, I just did it myself, but not been able to pinpoint if this will stop, anyway I thought to share this info:

1) Settings>General>iCloud>Documents & Data... Scroll down and have the customer turn off Use¿Cellular Data
2) Settings>iTunes & App Store> Scroll down to AUTOMATIC DOWNLOADS and have the customer turn off MUSIC, APPS, UPDATES
3) Settings>General>Background App Refresh (turn off any apps that the customer doesn't want to automatically refresh with their information)
4) Settings>Privacy>Location Services (the customer will see all the apps that have the GPS enabled(Everything should be turned off except Setting Time Zone)

I hope this helps

Good luck

I have this issue to. I believe its a Mail connected issue. Check your battery usage and your Apps Cellular usage and I bet you see the majority of usage is from Mail (background activity).

Try setting all email accounts to Fetch. Hopefully the good people at Apple will resolve this soon.

I am having this same problem. I looked at ATT records and it shows HUGE 1 GB use at 3AM? What is up with that?!?!?!

has this actually worked for anyone?

i have the exact same problem and my data has reset on 21Sept and my usage has reached 1.6GB?! That's almost a months worth of data!! I've already switched off my background apps refresh and automatic downloads and cellular usage for almost all apps, except for whatsapp. It's not possible to use up so much data just by texting?! Solve my problem pleaseT_T

As posted above, I had the same problems and followed these recommendations from AT&T, so far so good, my data now seems under control....

1) Settings>General>iCloud>Documents & Data... Scroll down and have the customer turn off Use¿Cellular Data
2) Settings>iTunes & App Store> Scroll down to AUTOMATIC DOWNLOADS and have the customer turn off MUSIC, APPS, UPDATES
3) Settings>General>Background App Refresh (turn off any apps that the customer doesn't want to automatically refresh with their information)
4) Settings>Privacy>Location Services (the customer will see all the apps that have the GPS enabled(Everything should be turned off except Setting Time Zone)

Good Luck

I am having the same issue. I have blown through my 2GB data cap with minimal usage on my part. I checked the "System Services" tab under "Cellular" and it showed 148MB was used for "iTunes Accounts" since Sunday evening (9/21) when I reset the statistics. Today, three days later, I am shocked to see several notifications from Verizon notifying me that I am at 90% of my data usage for the month. I reset the statistics again a mere 6 hours ago, and am already at 46.2MB of "iTunes Accounts" being used. I don't have iTunes Match, and iTunes and App Store downloads are disabled over cellular. My cycle restarts on Oct 6. Looks like I will be paying for Apple's mistake, literally.

My battery like also has never been worse.

iOS 8? More like iOS "ate" all of my data and battery life.

iPhone 5s, Verizon, 16GB, iOS 8.0

iPhone 5, updated to iOS 8, having the same problems as everyone else. I've already blown through 2gb of data. I've had an iPhone since originally launched and have never used more then a 1gb for the entire billing cycle. Called AT&T and they said call Apple. Called Apple and they said they have not received any reports of this problem. I told them about this thread and was told each person could be different. I find it highly unlikely that we are all having the same issue with iOS 8 and it not be a software issue. Contact Apple so they create ticket numbers and see that they need to fix this problem. Is costing me extra money in data. I've had to shut off all cellular data. I've never had to do this and that's not a fix to this problem.
