Thank you Bear but that was one of the first things I did. I can see already today without barely using the phone it is still eating data. 10 minutes on Favebbok took like 15 mb. I'm not sure what to do. Apple says its Att and Att says its the IPhone. Starting to miss my never a problem...

Bear I have been with Samsung and Att for 12 years and never put a dent in my data. Since i switched to Apple in January is when the problem started.

Yes they did a network reset at the Apple Store.....all I can do now is monitor the situation for the next billing cycle....I am not the only iPhone 6 user having this problem....a simple Google search brought up many with this problem....

Went to the Apple Store today....the phone came back with no problems....they suggested the problem could be in Network Settings so we reset that and I downloaded the ATT app to keep an eye on my data..... I was also informed of some things about how ATT over charges data to many of its...

I have noticed this problem a few times on my iPhone 6 and thought it was the website I was looking at that was causing it to not rotate. Looks like the honeymoon phase of my new phone is over.

My Android never came even close to my data limit. Have had this phone 6 weeks and now I'm afraid to open an app. Now im locked into a two year contract with a phone I am liking less and less every day. Not sure why one phone would use more data than another on the same app but there's not much...

I did that as soon as I downloaded the app.

That was the first thing I checked.

I have already done that...and yes I double click home and flick each app after every time I am done using the phone........Apple wants me to bring the phone in to the store for a diagnostic and possible reset . They Yes I have done both....Apple wants me to bring the phone to the store for a...

So uninstall FB and Reinstall. Will try that but how will I know if it's corrupted?

As a last resort I will delete the FB app but I am just plain stumped as to what has caused this. My new plan even came with an extra gig (4 total) and I never do vids or music and it's only half way in my billing period. Took me many years to switch to Apple and was loving my new phone till...

I've already done that and it almost defeats have an app if it's turned off. FB and Safari are definitely the problem but like I say I am half way in my billing period and am not surfing any more than I ever did on the S4....it's a mystery

FB 24% safari 18% bat. I know from looking at app usage that FB and Safari are the main users but I have not changed my data habits at all since leaving the S4 for the IPhone. And the real kicker here is I am just past half way in my billing period.

I always turn off all apps when not using them that is why I am so confused as to the sudden spike in data usage.

hi I am new to iPhone. I use wifi where I can but in my first month with iPhone it is eating data like crazy. Do I have to turn off cellular every time I am on wifi? I hardly ever stream a video or music. Mainly use FB ...email...and surf web....with my s4 I never came close to using up my...
