Update on my situation. I found two things that were causing high data usage.
First, the podcasts app. I have tested and confirmed that if a podcast begins to download over wifi, and you move out of range, the download completes over cellular, rather than pausing. Personally, I listen to podcasts mostly on my commute. New podcasts start to download just after the app is launched. For me, this is usually in my garage as I'm pulling out of my garage at home, or the parking lot at work. At both places I have wifi, but then I immediately drive away, causing the majority of the download to use cellular data. I believe this is a design flaw.
Second, I have found that any app that uses location services consumes a ton of data. Three different navigation apps, including Apple Maps, use 1 to 2 MB of data while in use. And today I launched a retail app that uses location services and the built in maps to find nearby locations. Simply launching this app consumed 44 MB of data.
I had previously opened a case with Apple support regarding this and they recommended a factory reset of my phone. I did that tonight, so I will see if the second behavior improves tomorrow. As far as the first, just be careful to let your podcasts finish downloading before you leave wifi range!
i know nothing about that until i got my mobile bill recently!!!!!!!!!!
i am required to pay extra 300 bucks without really using the data!!!!!!!!!!
the records showed that there were over 1G usage in just 2-days time!!!!!!!!!!!!!
and on that 2 particular days, the battery of my phone just like a ****!!!!!!!!
i got a new phone when i found out that the battery was a ****!!!!!
the data usage became normal after i used the replaced new iphone5.
how to file a compliant btw?
After laying low for a while, still not using my ip5 cell data away from wifi, but still having daily 1-2 MBs of drain, I got 'careless' and didn't force quit all apps. Macnbaish, I think you're on to something about location services. I turned Datawiz back on and discovered that yesterday each time I left a wifi spot, 7 MBs drained instantly from my cell data four times. Could it be the new maps app? On the last day of my thirty day cycle, I get the AT&T text 66% notice. One full month of almost never consciously using cell data while away from wifi, and I've 'used' 140 MBs of cell data.
While I didn't exceed my data plan, I got absolutely NO use of the 200 MBs I paid for and didn't intentionally incur maybe 90% of what my provider reports that I "used"
iOS 6.0.1 better be the fix for this.
After a long conversation with AT&T high usage therapy group, I learned some things, last night. Apparently, when using 4G LTE you can reach speeds of 25MB per second. So, if you are using APPS like Netflix or Pandora that download buffering data to smooth out the viewing stream you can download 100MB in just 4 seconds. Why does this matter? 'Cause if you tend to channel surf or switch between movies constantly, you will be billed for any data you have downloaded but haven't viewed.
Part Deux: If the iPhone 5 loses connectivity with your wifi router then it will automatically switch over to cellular data without your consent. The icon on your screen may or may not give you an indication of the switch over but using the same data streaming scenario, alot of data can be deducted from your plan without your concious knowledge. If you recall, Verizon had customers experiencing overages on their iPhone 5s shortly after the phone's release. Verizon has already issued a patch for the iPhone 5 to remedy this problem. AT&T does not acknowledge and similar issues with iPhone5s on their networks.
Part III: Microcell users beware. If your iPhone 5 has problems connecting to your router then you are prone to cellular data overages. I use a microcell in one of my homes (lack of AT&T coverage in the area) and I suspect that part of my wife's overages is coming from switching from our home's router to the microcell. Microcell data with AT&T is billed to your data plan although it is using your home's ISP to relay your data. Only, your phone calls are totally free from air time billing if the call ORIGINATED initially from your microcell. So, now I switch my cellular data OFF whenever I am in range of my wifi router and microcell. Let's see how this works.
Again It goes beyond that. iPhone 4 and 4S users are having similar problems. I am still experiencing data drain outside of wifi coverage with the phone unused and sleeping in my pocket. Could be poor coding for the new maps app, even though the vector maps use a whole lot less data.
There is likely to be an issue with non active apps using location services drawing excessive data in a way they did not proir to IOS 6.
AT&T does not have to acknowledge anything, as it is likely Apple at fault with an unresolved IOS 6 issue.
AT&T will likely need to either refund a large number of customers with unexpected, out of normal usage overages, or they will have to endure the lingering after-effects of a large number of disaffected customers.
Perhaps they will just reap the benefits of huge profits generated by this issue by customers who are completely unaware that they have been defrauded by faulty software and uncaring corporate giants.
BTW. Kudos to DucNCover for getting some answers to some of the issues.
I feel for all of you iPhone users, this sounds like an issue that isn't going away soon, until Apple releases an update for all carriers, not just Verizon. I have been following this thread since the beginning, and it looks like some of you discovered some issues that need to be resolved.
I checked with a few partners at the firm that recently got the iOS6 update, and just about everything mentioned is happening.
Definitely an OS issue from my standpoint, let's hope the fix comes sooner than later!
Duc makes a point that needs correction just out of consumer confusion.
Megabits per second, not megabytes. There is a large variance of data used in a connection whe you have 25Mb/s of data being used over LTE (which is a very good speed to achieve). Megabits are not Megabytes, and Megabytes are what you actually consume. It's like estimating how much gas you're using by the MPG or MPH. If you have a 12 gallon tank you do not fill up with 60MPH's worth of gas, right?
Whenever a person uses their phone, the actual data rate usage varies based upon strength of the signal, carrier output and the kind of connection the carrier offers.
So, assuming that you can achieve and consistently hold a 25Mb/s connection, in reality you could only ever achieve a realistic download of 3MB per second, tops. Where an added layer of confusion lies is in if your app of choice has any throttles set within it to limit how much data it can use. Most audio streaming applications take this into account by offering you a 64Kbps, 128Kbps, or maybe even a 320Kbps audio stream. They do this on their end to prevent their data usage (where in a business, their data usage is defintely monitored and billed based on volume). It behooves them to limit it to customers who are actively choosing a specific speed and cap them in that way. There are also realistic capabilities of what you can stream in a given time. CD originated audio which is of higher quality than every music service out there would run at about 1.4MB per second of storage, making it impossible for it to breach more than 12Mb/s on just streaming audio.
So, suffice to say when you're dealing with video, there's considerably more bandwidth to consider and more customers to support as well considering the added bandwidth needed to support an equal amount of customers compared to an audio service.
Most streaming video services also use bandwidth caps not only because of their their own metered costs, but also because your hardware could not handle that kind of throughput in decoding. Considering that a 25Mb/s connection over LTE would result in a 3MB/s stream, you'd be looking at about 10GB for an hour's worth of video. Now, you're not seeing THAT high of a spike are you? A 3MB stream would also depend on what size and format the video would be sent in. A 25Mb/s stream of HD 1080p video (Blu Ray quality) would be about 25GB for a 2 hour movie depending on the movie... A 10Mbp/s of a 720p would look virtually indistingushiable to you and I on a smaller screen and would be more than half the size. The kicker is though that on a 3" screen you can't tell the difference between that and a 2Mb/s video at 720p, and neither can most people on a 26" screen. Netflix has been using an adaptive bit-rate model for it's app since the iPad 3 was launched earlier this year. Previously they had been using a variable bit rate model based upon connection potential but I don't believe I would've ever seen more than 4-5Mb/s on Netflix considering how soft some of the hardwired HD connections looked on my monitor at home.
Update on my own status. I returned my AT&T iPhone 5 back 3 weeks ago, ordered it from Sprint and activated it on Friday.
It's been a swing in the total opposite direction.
The LTE network in deployment by Sprint is very slow, very spotty coverage and there's serious speed deficiencies in normal use of 3G services provided by Sprint. The LTE is slower on Sprint than AT&T, likely due to lower deployment rates, slower network speed, etc... The 3G though is inexcusable. It's slower than my throttled AT&T speeds. I'm using Speedtest and getting like .1Mbps and in a few cases my ping was over 700ms and it would simply time out in trying to actually test the speed.
Just some food for thought on anyone looking to switch carriers out of this.
I'm hoping that the Softbank purchase gives Sprint some legs in catching up to AT&T on LTE coverage, because the less time I have to spend on 3G coverage on Sprint the happier I'll be on their network for the next two years. As it stands right now since I've just about lost my coverage twice this month for several hours at a time I'm not terribly pleased.
Well, I'm happy to report that my local ATT rep has finally not only admitted there is a data-leaking problem, he even knows that Apple is supplying a fix (as others have mentioned) with an OS update. What a complete turn-around from two weeks ago when "nobody else is complaining about it" and "you just have to be more careful with your apps" and "LTE just uses more data."
Now, let's just hope it works when it comes!
After restoring my phone to the factory image and doing a restore, my phone is now using normal amounts of data using location services again. This may work for those with older phones, that were upgraded to iOS 6. May be a long shot for iPhone 5 users as well.
Of course that doesn't solve the Podcasts app issue, I guess I'll just have to be very careful not to go anywhere while its downloading and hope a change will be made.
I'm talking to an AT&T rep right now who finally agreed to issue me a $15 credit for my 1GB overage, but it was darn near like pulling teeth. I activated my wife's new iPhone 5 last night, and since then it's gobbled up nearly 2GB on our data plan. I was downloading iTunes Match music over wifi, but it appears that it was using Cellular Data instead.
We're taking the phone to the Apple Store tomorrow to see if the folks there know anything about it, but if Apple's going to release iOS 6.0.1 to remedy this issue, they better do it quick.
