The iPhone 5 uses Cellular Data over WiFi?

so only verizon was updated?

I'm on Fido, and it seems to be working ok. I can go on wifi and my data usuage is halted. First, I was told to reset

Network Settings & Secondly my carrier following Apple's advice told me how to save data usuage on my phone. I believe you can find this same advice on Apple. Nice to go back to normal :-)

Just picked this thread up this morning. I am on AT&T using version 13.0 in carrier settings. Connected to WiFi only this morning and I reset my statistics. Already up to 382 MB just browsing, email and some video. WHAT!!!!!! if this continues I either have to stop using my phone or pay the overages which will certainly come. I noticed that after the entire familly upgraded to iPhone 5 during the last few days of the billing cycle our usage normally around 1 GB/month (my wife and I have wireless at work and my son at school) is usually around or less than 1 GB/month, only using cellular data when in the car. Suddenly it jumped from some 700MB to 1.6 GB in a couple of days. I attributed this to iTunes and the inability now to download music from match without great difficuluty and screwing around, BUT perhaps not!

So I am on ATT, and I have noticed the exact same thing. I have called ATT and they said they cannot control what the device does. For two weeks it usded 3GB of data already, and I have never passed the 2GB mark on my old iPhones.

Based on the ATT data usage reports I have noticed that 80% of the usage happened at night, around 12:00AM - the phone was downaloding things big as 200MB-280MB whilie I was asleep.. I have WiFi at home, but also I have the iCloud backup turned off and use cellular features off for music apps etc.

Apple acknowledges issue and sends a fix to Verizon users phones!

New Knowledge Base for this even.

yep, but how about ATT or other carriers? Read also that in Australia Telstra they have similar unusual data usage

ksmolka, if I were you I would just continue to call and register complaints with AT&T. Verizon took about a week to fix [at least part of] the issue once they knew there was one. I must have called 5 times with varying degrees of receptiveness on their part. You have to find the right CSR/tech rep. I know, it shouldn't be that way.

But I am not sure this update will fix what I think is a related issue. We have two phones, both set up in the store. Mine uses 3x the data that his does doing the same task - checking mail, for example. Verizon billing data supports this find.

But I went on a 1 hour walk away from my wifi with Cellular Data on and some Location Services and saw only minimal Usage creep, not anything like before the update. So this update might have done something else to help plug the leak. Hopeful!

I thought that Australian warning was so vague, so careful. Not blaming anyone. Not saying anyone is doing anything wrong. Wonder if the fcc will do something similar here. I mean the phones just use more data, period. People need to be aware of that. But they should not use unaffordable amounts of data without making the customer aware of it before buying the phone. Seems like a bad practice.

You might want to turn off your Ad Tracking and Diagnostics - that stuff apparently also gets transferred at night.

My carrier is Fido and they told me to go to General..look for reset down at the bottom ..click on that and you will see reset network settings. This will automatically turn off your iphone. When you turn it back on, your carrier should read 13.1

Also clear all running apps daily as they eat up data.

Another way I was told to save data usuage. Go to Privacy and click on Location Services ...Leave that on but turn off all apps. As this also drains usuage. When you go to use an app that requires data..it will tell you to turn this app on while you use it.

Hope this all makes sense.. I have to go to work but I will give clearer details later if you couldn't find the fix.

Two things to note:

You did not use that data at 12:00AM. That was the time cumulative data over a previous period that could be up to 24 hours from your local tower was reported to the billing system.

WiFi is turned off on the iPhone 45 seconds after the phone goes to sleep, to preserve battery life, unless the phone is plugged in to power. So it doesn't matter if you have WiFi available, if you have background processes on the phone that use data while the phone is asleep and not plugged in the content will go over cellular, not WiFi.

I'm not saying you don't have a problem, but from the information that you have provided it can't be determined what the cause is.

After the verizon carrier update went out yesterday, ive been checking my cellular data usage on my phone while its been asleep while ive been at home on wifi. Whereas before the update, it was chewing up data when it was sleeping while on wifi, after the update it hasnt gone up at all until i left my house. So it is still using wifi while on sleep

CORRECTED!

On ATT

Cell ON/Wifi OFF

Reset Stats

Navigate

Cell data usage goes up

Cell ON/Wifi ON (connected to my home wifi)

Reset Stats

Navigate

Cell data usage goes up

Cell OFF/Wifi ON (connected to my home wifi)

Reset Stats

Navigate

Cell data usage doesn't go up

All Navigations were simple refresh of mail inbox. Bug or a feature?

Actually on Cell OFF/WiFi ON, the cell counter didnt go up for me. It did though on Cell ON/WiFi ON, but a smaller amount.

Corrected!

If Cellular data is off and cell data usage as measured on the phone goes up there's something seriously wrong with the software. Cell data off should mean OFF, and always has in the past. But you must measure it on the phone, not on the carrier's web site, because the web site time stamps are the time accumulated usage was reported to the billing system, not the time the usage occurred.

A good tool for this, beyond settings/general/usage, is the Dataman app.

If both Cell data and WiFi data are on there will be some small accumulation of cell data, but it should not be significant UNLESS the phone is asleep, which turns WiFi off.

Well interesting I posted and then I went back and tried it again and now I'm not seeing the increases in Data Stats in the Cell section of usage I was seeing this morning. Not sure what to think now.....

I seem to be having the same issue on iPhone 4S, with iOS 5.1.1 on AT&T. My data usage spiked duing my August billing cycle (forcing me to go to the 5 GB plan from the 4GB in an effort to avoid an overage—to no avail, I wound up using nearly 7 GB of data). I managed to burn through my entire 5 GB plan within four days of my Sept. billing cycle (which ends this Friday). I've had the phone in airplane mode as much as possbile, but have already incurred three overages this month. I'm on Wifi at work and at home...I knew there was no way I was burning through that much data on my 25 minute commute. I guess I'd better start calling AT&T.

I saw above that someone had AT&T v. 13.0. I'm on 12.0. How does one force a Carrier Settings update?

Cheers!
