The iPhone 5 uses Cellular Data over WiFi?

Just wondering.. how many of us tried to use SpeedTest app while on Cellular data to check the speed of internet.

I did test LTE speeds because Apple rep needed that data as he's been using me to figure this out. I was hitting 4.6Mbps download speeds and 2.9Mbps upload speeds in Columbus,OH

That's all going towards data right. I have started using Iphone 5 since Monday, and my cellular data usage was 113 MB this morning, but i did around 5 speed test that used about 93 MB of my data.

That's interesting, because speedtest itself uses under 1 MB per run. So 5 runs should be no more than 5 MB.

Exactly....what people are not realizing is even though you may be on LTE and its fast (I get 20 MB+ downloads in Tampa Bay), you are only getting your information faster...not getting more information.

I cannot count how many times even the ATT reps are saying "you'll use more data 'cause your on LTE"...NOT SO says the cat. LTE corollates to speed, not the amount of information. You may be able to do alot more things quicker than before thusly eating more data, but if your doing the same things as before LTE (like me), I'm only getting my data faster....not more of it.

Which is why I am so confused by these data amounts.

It depends on the download speed. My download speed was 21 MB (while on LTE) that could have used 21 MB worth of data in 1 test.

I don't know i could be wrong.

thats a good point adzees....I recall many tests increase your file size when speeds are greater, but Ookla should know better than to be throwing 20 MB files around for tests....thats crazy. If you've got a few hundred new iPhone owners checking the blazing LTE speed AT&T offers over and over again...you could have one **** of a problem....and one **** of a data bill...(if you're on mobile share)....

i turned off cellular data, and ran the speed test over wifi. Once done i checked using Datawiz it showed me the increase in wifi data usage by the speed showed up on speed test. There may be other background things involved but i know for a fact that i have never ran speed test while on cellular data before i got Iphone5. I was just curious about the LTE speed thus i ran number of speed tests. I have every thing turned on now. I am not going to run speed test, and check it back tomorrow.

Wow. Lots of good info in these posts on how to adjust settings to choke off the numerous background processes that use cell data. All worth following. My experience was similar - 80mb in less than a day on AT&T 4g LTE new iphone 5. Took the phone in to Apple today and the tech rebooted the network as mentioned earlier. Called AT&T and the rep refunded the extra use charge - they are aware of the problem. One other trick the Apple guy showed me not mentioned yet - if you put the phone in Airplane mode, you can go back and turn on wifi in Airplane mode and the cellular system is completely off. I do that now whenever I'm on wifi downloading stuff and I don't need the cellular available. Hope this is fixed soon - like the iphone 5 a lot. In the meantime, keeping a close watch on cellular usage, both on phone and AT&T text service.

Has anyone used the Verizon settings fix? Are you still having this problem?

I'm on the Telus network here in Canada and I'm experiencing the same issue with my iPhone 5.

I've never exceed my data usage, however since I've had my new phone I'm using data at times I'm at home, on my wi-fi connection and sleeping!

I downloaded the patch and am still having the problem

I turned off data right away when I got my iPhone about a week ago since I'd heard about this issue, I'm on AT&T's 200MB plan and rarely go over. Turning off data is an inconvenience but since I'm on WiFi most of the time it's ok for now.

I did the network reset about an hour ago as someone mentioned here a few pages back and turned on LTE. I'm still on WiFi but the phone hasn't used any data. Before it would consume a few MB's even on WiFi.

You all should try this and see if it works:

Settings > General > Reset > Reset Network Settings.

That was the first thing the senior advisor at Apple support I spoke to had me do. It did not stop my phone from draining cell data while on wifi.

Shiparch...

Thanks for passing on you tip, it appears to be working for me too...

I Reset Network Settings and with both WiFi and Cellular Data On, WiFi is now clearly the prime connection.

DataWiz shows a few bytes of Cellular Data every 10 minutes, an occasional few kB. Quite acceptable, in a monthly budget of 1.0 GB...

Prior to that, I just got into the habit of turn Cellular Data Off while on home or office WiFi.

Doing that gave me zero Cellular Data usage, as you would expect.

It's no more tiresome than turning off WiFi, Bluetooth and/or Location Services when

you don't need them [to conserve battery].
