IOS 8 High Cellular Data Usage

Upgraded my wife's iPhone 5 32GB to IOS 8 yesterday. About an hour after I upgraded she got an SMS from her provider saying she only had 100MB left of her data package. About a minute later she got another SMS to say it ran out. I reset Cellular Usage Statistics and bought another 250MB data bundle.

About 2 hours later she got another SMS saying she had again used up all data and that out of bundle rates apply, when I checked Data Usage it had used 297MB. She did not use the phone at all during this time.


I have disabled everything under Use Cellular Data For: long ago, except Contacts, Find iPhone, Maps, IMDB, Mail, Settings, Weather and WhatsApp.

None of these Apps had excessive usage under them, some a few KB. System Services had used 404KB.


Personal Hotspot was Off.


Everything in iCloud except for Find My iPhone is off. iCloud is signed in.


Use Cellular Data is off under iTunes & App Store


I have gone through all the Apps at the bottom of Settings and none of them have Cellular Data active.


iTunes Radio under Music is not set to use Cellular.


Is there anywhere else I can check what would be using so much data, have turned Cellular Data off for now?

I am at a loss, I upgraded my iPhone 5 16GB the same way as my wife's and I have not used any extra data, sitting at 247MB since September 1st.

My wife's phone has not changed since before the upgrade, so all settings were the same and it has never used this much data.


Any help would be appreciated.

iPhone 5, iOS 8

LONG time Apple user and fan. I am sad to say that this feeling is diminishing.


In my opinion, these continual bugs – which is, without ambiguity, what they are – caused by updating and requiring end users to research, investigate, reset, restore, etc. simply to get the phones to operate and perform as promised and expected – and the associated user costs because of them – should fall entirely under the responsibility of Apple.


How a user is to be subject to data overages and additional costs because Apple has yet again failed to engineer an update properly is beyond me.


"Mysterious" midnight data usage aside, the ongoing trouble our family has been having with messaging issues and calls going to the wrong phone is a strong and clear message that Apple needs to focus on making things work before adding complications.


They are fixing things until they break, and it needs to stop.

Jul 23, 2015 6:09 AM in response to The Blue Chunks

Those "mysterious" midnight data usages were one of the red flags that convinced A T & T and Apple that something was wrong with my phone, in fact. Beginning on the very day that I got this iPhone 6, every evening between 11:20 PM and 11:51 PM (when Lord knows I'm snoozing away), usage is being logged: anywhere from 1570 KB to 22905 KB. For weeks! And all the time my phone is sitting on my kitchen counter, in sleep mode, set to connect to my wifi when it's in my home (and we have a strong router -- we even receive the signal outside).


The truly ironic thing in all of this is that A T & T gave me a really hard time when my husband and I upgraded: hard sell to change my plan because one of my lines has the old "grandfathered" unlimited data plan on it. They were continually pitching that no one needs unlimited data now, because phones are set up to automatically detect and connect to wifi -- and that's what the cell phone companies want you to do: use wifi rather than cell data.


In good faith I did that! And I got overage charges for it!

Jul 23, 2015 7:13 AM in response to The Blue Chunks

It was the mysterious midnight charges that convinced the guy at the Apple genius bar to replace my phone. (That and he wanted to go on his lunch break!) But I haven't had a problem at all with the new phone, so clearly it's some defect in the actual phones or in the way they're set up that nobody knows how to fix.


Yes - print out those usage reports and bring them. It's hard to argue with those middle of the night data dumps.


But they really, really need to fix this! And the fact that it crosses all carriers, to me, signifies that it's Apple's problem.

Hi all-


My understanding is that overnight is when AT&T has chosen to update the day's activity; this makes little sense to me, but that's what they said. This, after having sudden overages occur at night; when we asked about this, we were told that the phone, once asleep, CANNOT RECONNECT TO WiFi and therefore uses up the data plan to run updates.


They have removed our overages every time this has happened (3 or 4 times).


I don't know if it's still the case about re-awaking and disconnecting from WiFi.


We use an app called DataMan that does seem to track real-time pretty well, though.

Jul 23, 2015 8:36 PM in response to maryv820

Prior to the introduction of LTE, Wi-Fi would obviously be the fastest connection available and the iPhone would, by default, connect to Wi-Fi. However, I'm starting think that the LTE connection could now be overriding the Wi-Fi connection, because it could theoretically be providing a higher speed connection for some customers.


If so, Apple should make sure that their devices default to Wi-Fi no matter what, even if LTE is faster. Not sure if this is the case, but if you're having this problem and are in communication with Apple, you may want to ask them if this is a possibility and ASK THEM TO FIX IT.

An update, since this has been eating at me and my wallet:


Since both my husband and I got virtually identical iPhone 6 models on the same day, I'm able to do a comparison as to my usage vs. his usage on data. He's on a higher data plan than me, BUT --


I had my phone wiped clean and reset; he did not. Mine was eating up data; his was not. I pulled up my data records and printed them out and did the same for him. I had turned everything off on my phone -- push notifications, background updates -- you name it, it was turned off for cellular usage. But the charges still were accruing. His phone, however, showed activity: he has enabled all of these notification and is always on his phone when connected to our home network -- but no data was logged as being used.


What was really suspect: As I was on the phone with Apple Care on my landline setting up my phone after the reset, I received a 48 second voice call on my cell phone. It showed up as a data charge on my account. A voice call? And this is after the phone had been reset!


I went to the A T & T store this morning with my husband and his phone and all my records and his records in tow. Oh, yeah, they were skeptical at first and tried to fancy footwork their way out of it. First it was an iMessages thing -- until they saw my husband also had iMessages enabled and wasn't being charged for them. Then they saw all of his notifications enabled (and mine were not). And they could not dispute the odd fact that I was charged data for a voice call.


With three (yes, 3) of their employees hovering over me (for nearly an hour), it was finally determined that I probably need to have my SIM card replaced, since that is what connects the phone to the network.


I left there this morning with 402 KB as a reset on the SIM card and we turned my cellular data back on for voice and data. In 8 (eight) hours, it's logged 392 KB of data (which we all know is minuscule) -- a fraction of what it had logged in the last several days (in fact, in one day I racked up nearly 92 MB when I had not left my home network previously). And I've been out and about all day today, too!


Get your SIM card replaced!


Hopefully this has fixed my issue. I relay all of this information in the hopes that I'll help someone fix their issue, too. My frustration level these last few days has reached the breaking point, and no one -- absolutely no one -- should have to go through this.


I will obviously update if the SIM card replacement has not, indeed, resolved the problem. I intend to get to the root of this, one way or another.

Jul 24, 2015 11:52 PM in response to maryv820

I'm now prety much convinced that this si not ans Apple or an iPhone problem, but a sophisticated scheme by carriers to expolit low data users and get them to pay for more data.


I believe this because I am a low data user myself. When I was on 3G with Orange (in the UK), even with tethering, my monthly usage was less than 1GB .


On 4G with EE (who own Orange) I'm on a 4GB cap. For several months this year I've experience sudden and unexplained data leakage. I had looked at all possible causes; the phone dropping WiFi while I was listening to internet radio overnight; Facebook video streaming, background app refreshing. I responded by turning off mobile data for all apps which stream AV services. There was no change. The only common thread seemed to be that the data loss typically occurred close to the end of my monthly billing period, but only if my data use for the month had been low. As long as I kept my data consumption to a daily average that cumulatively led to around 4GB + or - 10% there would be no data loss. If my data was very low, around the third week I would find around 2GB had vanished literally within the space of an hour or two. On one occasion, as I was heading home from one of the shops where I have a workshop, I checked my data meter to find that only had around 350MB left for the remaining 10 days whereas when I had checked it that morning I'd had around 2.5GB spare. EE's response was always the same: "we can sell you an extra data package to get you through the rest of the month, then maybe we can talk about upgrading you to a package that better suits your needs".


It came to a head one Saturday when there was an anomalous loss of my entire data allowance the day after it had refreshed. When I spoke to customers service I got the usual mantra of "I'll top up your account this time to get you through the month and then we need to talk about upgrading you..." until; I poiunted out something that the guy in customer services had missed; this data loss had occurred over a period of hours and that "the end of the month" which he was assuming was only a few days away, was actually 30 days away...


I was met with an embarrassed silence and when I pointed out that, as fast as 4g is, any phone that handled data traffic at that rate would probably have gone into meltdown.


In fairness to him, he admitted that there must be something wrong, gave me 12 GB of data; they stopped metering my account while they investigated the problem and, in due course, when they started voiding my account details and treating me like a new subscriber every time I moved from one cell to another, they gace me a new SIM card and the problem has not recurred since.


Now, it may be that it's not a conspiracy to defraud at all, but it seems that as long as the comms provider's first approach is to exploit it to sell you more data, there is little incentive to fix the problem...

Jul 26, 2015 5:02 PM in response to Eltham Jones

I can presume, hopefully, that my personal issue has been resolved.


When my phone was reset at the Apple store on 7/22, the data charge issues seemed to continue. However, when I had my SIM card replaced at the A T & T store on 7/24, I have accrued virtually no data charges on my line.


Prior to having the SIM card replaced, I was logged as using 92 MB in about 8 hours (after the phone was reset). Since the SIM card has been replaced (approximately 57 hours according to my calculations as I type this), I have logged a total of 948 KB. That's a monumental difference and more in line to my normal usage (I normally use a max of 50 or so MB per month), since I always connect to our home wifi for heavy data usage.


I have made it a point since this SIM card was replaced to (while connected to my home network) surf on the web, upload photos, text, make and receive phone calls, send texts with photos attached and update apps. My only conclusion is that either I had no SIM card whatsoever or a completely malfunctioning SIM card which prevented me from ever connecting to anything other than the cellular network for data usage.


While I'm pleased that I apparently got my issues resolved, I urge everyone else who is still tackling this to not only visit Apple but also to pursue this extensively with their carrier. It took 3 employees (and ultimately the A T & T store manager) to authorize that I get a new SIM card - and that was only after my husband (who was with me) balked about the bunk I had endured already.


And, @Eltham, as a personal reply to you: I see your point. For quite an extended period of time prior to my SIM card being replaced, the 3 (yes, three) employees at the A T & T store were trying to figure out how to bump my data plan up from 200 MB to 3 GB. But, alas, I'm on one of those older contract plans that I just renewed (I've been a customer for too many years to count and these plans won't be available for renewal after September 1); so my data plan simply could not be bumped up -- of course, at an additional cost to me -- but I was under contract, so no changes could be made to my plan at all. This was quite vexing to them, for what were they to do if they couldn't charge me more money? That is, finally, when one of them deduced that perhaps my SIM card (and the connectivity) was the issue.


BINGO.

I have the same problems with unbelievably high data usage with my 5c and iOS 8.4 and changing the SIM card did definitely not work for me! It all started two months ago, when I unexpectedly reached my 500mb after 3 weeks. I never reached the 500 mb before! Also, the battery gets really hot while using safari. That's when I started looking into this and read of all the problems. For me, it's Safari and Documents & sync, which use the most cellular data. I look at mobile websites for about 5 minutes and 50 mb are gone! EVERYTHING in my iPhone settings is turned off (iCloud, Updates, Itunes and App Store etc.). I even changed my provider, so it's definitely not the SIM card. I reset my iphone via itunes and set it up as a new one. Still the same problem!


When will apple finally address the problem and find a solution?

Aug 11, 2015 3:19 AM in response to AppleSucks99

Thank you for this info. Hope it helps other people.




AppleSucks99 Ok so I am going to tell everyone what has started working for me. Long story short I have the 2gb plan with the Iphone 6 on verizon (had the 5 with the same issue) and go through it within 5 days of the new cycle. So hopefully this next piece helps everyone like it did me. First I am on wifi about 90% of the time either at work or at home. So i tried doing everything Apple said to do and turn off cellular data and the back ground app refresh (which is bull crap because some apps in their own setting still have this on and cannot be turned off) which did me no good. So what I have found that works for me is to actually turn off the LTE radio and only be on 3g when connected to wifi (like at home and work). This has dropped my cellular usage back to a normal rate and for the past 2 weeks have seen a drastic improvement in my overall data consumption. I have even gone a couple of days with no data usage what so ever. So my conclusion is this...the LTE radio is always on using data even when connected to wifi. Apple needs to fix this asap. Whenever wifi is connect IOS should shut down the LTE radio until wifi connectivity is lost. Hopefully others can try this out and report back if their data usage looks to correct itself. Oh btw Apple is a bunch of phags!

Hi. What did you mean by you had the iCloud Drive switched off? Did you delete or remove your iCloud account or did you just disable the 'automatic backup'?

Re: IOS 8 High Cellular Data Usage

in response to webdevandy


Since my last post Ive ran my iPhone 6+ with no iCloud enabled across 2 days. Minimal increments in cell data usage. All good. This evening I finally switched on iCloud before heading out (but not iCloud Drive). Within an hour I had used 16MB of data! The culprit (for me anyway) is DEFINETLY iCloud. I should also point out that there was no interaction on my part. I did nothing to engage iCloud. No checking email. No taking photos. Nothing. iPhone was simply in my pocket doing what it had done the previous 2 days when iCloud was not switched on. So the next question is which part of iCloud is at fault? Along with iCloud Drive switched off I have now disabled Photos. Everything else is switched on. I will now monitor tomorrow and see if this resolves the data issue. AndyG.

Yes, I do remember someone telling me you have to have an LTE-capable sim as well for it to work well with an LTE-capable device. I'm not so sure if this has anything to do with it hogging so much data usage (but for you it did). Thanks for reminding me about this.


So if you are upgrading to an LTE device still using your old number or old sim -- you have to have it REPLACED with an LTE-capable/compatible SIM. Funny how a lot of telcos seem to leave or forget to give this information out.

I've been having the same issue ever since iOS 8 was released. Was hoping these subsequent updates would've been helped but nada. Once I switched to AT&T's Mobile Share Value data plan, my wife and I have seen significant data usage each billing cycle. And now get pestered with the text & email notifications from AT&T that we've used 75% of our data, or 90% etc. Besides texting via iMessage, Facebook, Candy Crush, and Words with Friends, no out of the ordinary data usage than before iOS 8 was released.


I started disabling features throughout my phone including the features you listed from AT&T. I've also been leaving my Cellular Data turned OFF when I'm in Wifi range everywhere. Even piggyback my Personal Hotspot on my work phone which helps too.
