The iPhone 5 uses Cellular Data over WiFi?

Updating now. Hope it helps.

Count me in as well, I've just updated and hope it works, lets all keep our fingers crossed.

I think if there is a data leak fix we would have to discover it first.

I dont think Apple will publish data leak fix in the release ntoes, it would then be admitting there was a data leak problem, which in turn would mean customers could go to their carriers and demand a refund for the couple month or so since the iOS 6. Just my logic on why it may not be listed.

I just updated mine and it also updated my Verizon too. Verizon I was at 13.1 and now it is 13.3. The phone is at 6.01 now as opposed to 6.

I'll clear my usage and see what happens.

Release notes for iOS 6.0.1...

This update contains improvements and bug fixes, including:

- Fixes a bug that prevents iPhone 5 from installing software updates wirelessly over the air

- Fixes a bug where horizontal lines may be displayed across the keyboard

- Fixes an issue that could cause camera flash to not go off

- Improves reliability of iPhone 5 and iPod touch (5th generation) when connected to encrypted WPA2 Wi-Fi networks

- Resolves an issue that prevents iPhone from using the cellular network in some instances

- Consolidated the Use Cellular Data switch for iTunes Match

- Fixes a Passcode Lock bug which sometimes allowed access to Passbook pass details from lock screen

- Fixes a bug affecting Exchange meetings

MacFormat Rumours indicated (refer earlier post here) that 6.0.1 included a fix for a WiFi connection issue.

And here it is: hoping it works for you Darell.

>>And here it is: hoping it works for you Darell.

Aw, you're sweet. 😉

While I'm usually one to jump in with both feet, I've decided to test the waters with my pinkie toe first this time. I'll stand by for a day or two before updating and see what folks come up with. You'd think the change would be instantly observable if they indeed fixed this. When in WiFi, no data should leak out over Cellular. None. Just like before 6.0.... Right?

I'm still not confident that the folks at Apple have that as their goal.

I can tell you two things, Darell,

One, 6.0.1 does not plug incidental leakage while on wifi. I'm still seeing at least 1 MB a day drain while on wifi (40 MBs per month out of 200MBs I pay for) It also leaks a good bit while out of wifi with sync disabled and most apps force quit.

Two, since I didn't download Datawiz before IOS 6, I have no proof IOS 5 wasn't leaking small (but not insignificant) amounts of data while in wifi..

I agree with you, NO data AT ALL should drain while on wifi.

Time will probably bear this out.

Does anyone have proof IOS 5 doesn't leak any data while on wifi?

I have not followed this thread in entirety but doesnt visual voicemail drain a bit of data as long as its on?

When cellular data is turned off a warning tells you that visual voicemail will not work, so I am assuming it is constantly polling something to see if a voicemail is present.

Not completely sure how VVM works so correct me if I am totally off.

On my iPhone 5 I have everything turned off that I can (location services, etc), no pushing for mail, and only have Calendar & Contacts syncing via iCloud. This current config has reduced my data drain within wifi to be nearly nonexistent...after deleting the new Podcast app.

So today, I updated the iP5 to 6.0.1. Once away from my home wifi, driving around town, the phone used 8 megs of AT&T data in less than an hour (using Dataman to track usage). So I can see no improvement after today's iOS update.

Call it paranoia, or just conspiracy theory gone wild, but I can't help but think carriers WANT smartphone users to be more aware of how much data we are pulling/pushing. AT&T certainly has my attention. I am suddenly at risk of running over my 1 GB data plan...which up until now had never been a concern of mine (never used more than 75 megs in any of 24 previous months). I hate having to monitor something that I had never worried about in the past. Like all of my peers in this "support community", we have enough crap to think about; Apple products have always been a joy for me, something always there to help me, not to mention a thing of great beauty and engineering -- but now I am just ******.

As an avid a long-term Apple addict, it's amazing how this one potentially expen$ive data usage issue has tainted my opinion of the entire company -- mostly because they do not admit publicly that there is indeed a problem, and that they are working on a solution. I had hoped that, due to the pain of bad publicity, Apple merely chose to quietly fix the problem with today's update. No such luck.

I'm a consultant who, at least as of today, can't recommend purchasing any iOS cellular devices to my clients. That wonderful sync of calendars, contacts and music via iCloud had just become complete with the purchase of a new $4k+ MacBook Pro Retina -- until I updated the iPads to iOS 6 and bought the iPhone 5. That's when the blades began to turn and the turds began to drop. So much for the glorious iCloud sync.

Anybody else notice that after updating to IOS 6.0.1 the AT&T carrier setting went from 13.1 to 13.0, funny one would think that it would go up to 13.2? Anyway I saw this happen both on my iPhone 5, as well as my wifes 4S.

iOS 5 "leaked" data while on WiFi. So did iOS 4, iOS 3, iOS 2, and iOS 1. It isn't a leak; there are some things that can only go over a cellular network, such as Exchange push alerts. And WiFi is off when the phone is asleep, so a cellular "kick" is needed to wake it up for notifications.

VVM sends your voicemail recordings to the phone over cellular data in near real time. The phone does not poll; cellular has the capability to wake the phone remotely (as the phone is always listening).

re. all other iOS's leaking: Everybody I know who is on a relatively tight "MB" plan, and who switched from iOS5 to IOS6 has either gone over their plan limits after never having done so before... or is at risk of doing so after just a week or two of using the new iOS. I have friends who have never used more 100 MB in a month in several years of iOS ownership, then two weeks after the switch to 6, they gobble up multiple hundred MB's - on pace for a GB+ month. And guess what the only thing they did differently besides switching to iOS6.... the only change was to turn off everything they could find that might use cellular inadvertently. Something they didn't even bother with while on previous iOS's. Other OS's might have leaked. They didn't leak like this.

re. Sleeping: When plugged in, and on WiFi, the phone still leaks. Isn't WiFi supposed to stay on when plugged in? And the leaking (sometimes significant!) happens when the phone is fully awake. Asleep or awake doesn't seem to matter. A couple of nights ago, my phone made it eight hours through the night plugged in as usual, set up as usual. Running the same stuff as usual. And it used ZERO cellular data. How can it go all night (emails came in as usual) and use no data if it normally *should* use data?

I can live with small kb leaks. But when I turn cellular completely off, everything except Visual VM works as it should... Every alert still comes through except VVM. If VVM is the only benefit we get from having cellular data on during WiFi usage, then that VVM is a huge waste of resources (I'm talking about random multi-MB consumption here that seems to offer us no other benefit than VVM). The consumption is not consistent, so we really have very little way of knowing just what is consuming the data.

And under the heading of "I can live with small leaks" comes the issue of 30-40 MB burps of data that happen when cellular is first switched on after being off for a time - or in the case that others have noted - when WiFi coverage is exited.

I understand that there might be some small hosekeeping items that need cellular now and then. A few kb per day aren't going to hurt anybody. But when whole lumps of cellular data come through that are larger than some people's entire months' usage... we have to step back and admit there's a problem that needs fixing.

This is all fine and dandy if we have huge or unlimited plans. But the TelComs aren't giving those plans away, are they?

I agree with you on that last comment. Small "leaks" are normal. These people complaining of 100's of KB when they aren't using their phone are just making a mockery of the real problem. Stuff downloads in the background all the time on a smart phone. Shoot, even people who have contacts linked to Facebook have to realize that when people change their photos, they will be downloaded to their contacts. That's Meg's right there. My problem was that my phone UPLOADED 8GB at once while on wifi and plugged in in the middle of the night. My phone thought it was on WiFi but was using cellular. Te only thing that could upload that much data is backups. My phone isn't supposed to be able to auto backup over cellular. Those are the real problems that are/were going on.

Assuming that you "know" me that statement is untrue. There are certainly people whose data use has gone up dramatically after updating, but it is far from everyone. My data usage has stayed about the same after updating, and I "know" many other users who have not noticed an increase.

So rather than make generalizations that are not true it would be helpful to focus on what those who DO have this problem have in common. Specific apps, for example? Just as a start, Facebook had a major update with lots of new features just before iOS 6 was released.
