iPhone X EXCESSIVE data usage

Especially given your response to welafever above, I don't understand your issue.

• Your WiFi plan is not limited.
• Your cellular data has a huge capacity.
• You are concerned about a few megabytes of use per hour.
• Why?

No, I read that, I was just trying to understand what is going on and to try and help. I know you are frustrated but there is something happening. I am going to let someone with more experience try to help you.

I have been having the exact same issue with my iPhone X. The amount of data it has been chewing through is INSANE. I had an iPhone 7 previously and never experienced this issue.. Even when I am connected to wifi it is eating through data. I won't even be using the phone and it will chew through 1GB of cellular within a minute WHILE connected to wifi! I have backed up my iPhone X to the exact settings as my old iPhone. I have contacted apple numerous times and they state "there are enhancements on the iPhone x that connects to more apple services than the iPhone 7". There is no way that these "enhancements" should be causing me to go over my monthly data usage within a few days. And if for some reason it is because of these enhancements, what is the point in even having this phone? I have to keep my cellular turned off so I can't even use the "cool" features that this phone has to offer.

Apple has not been able to figure out what is causing the excessive usage, and neither has my phone provider (ROGERS).

Did you by chance figure out what is causing this? It is driving me crazy. I don't even want the phone anymore!

I have owned an iPhone for years, but then the day I switch to the iPhone X my data usage goes haywire.. nothing has changed other than the phone I am using.... I've never gone over my data usage. This phone has been using more data in a minute while connected to wifi with wifi assist off, than I was able to use in an entire month with my iPhone 7. It just doesn't make sense to me. Apple told me to "turn off my cellular data" to solve the problem. I don't understand why cellular data is being used why I am connected to wifi, and while most of my apps are turned off for cellular data.

Bam. Yeah I am suffering the same thing, the first morning I set the phone up I was connected to WiFi and backed up my phone whilst connected to my laptop, it finished up date I unplugged my phone and went to work, once at work as you do I looked at my new iPhone, not much longer I received a text to say I only had 1000 mb of data remaining out of 28gb. I checked my app and it was true all gone. I have been with Apple for 10 years and never have I gone above 10gb PCM. Only the other day I has 1.4gb remaining came home and checked some time later only to find out I was back to a big fat 0 of data left, it’s getting a joke, turn this and that off, what’s the point in having a £1150 phone that I have to switch stuff on and off all the time, I am waiting on a call back from Apple to see what they say, failing that I will be taking the phone back to my service provider and telling them to stick it where the 🌝 dont shine. Hope this helps somebody else who has same issue.??.

I got the X a month ago and just discovered today that I've burned through 1.8G in 3 weeks. I'm in WiFi almost constantly and rarely use the phone out. My normal use is 200Mb per month. I have yet to figure out what is going on with this X gobbling up cell data while I'm in Wifi. Neither ATT nor Apple seems to be able to figure it out.

There was no packet switching when the 3270 was popular! On the other hand, I don't think that it really matters whether it's private line or packet - in both cases, it's a transmission protocol that's intended to reduce undetected errors to a minimum. I think you'll agree that 100% error-free transmission is not possible.

Your explanation makes a lot of sense. Unfortunately, each app is given individual control over message retransmission and conceivably they could all make different decisions, not unlike the humans at the 3270 consoles.

Hi! Juan from Argentina here, this is my first post. I´m having the same issues as described before, excesive data usage on my iphone X. This is my first iphone ever, i come from Android, and i never had issues before with my 5gb carrier plan. I read all this retransmission thread and i sincerely got lost along the way (not much of a tecchie). In simple words, what do i have to do to solve my problem?? Thanks in advance

IF that is the cause of the problem, then don't use data when your cell signal is poor. To oversimplify, the problem is comparable to listening to someone speak in a noisy environment and you continually ask for a repeat.

That clarifies things.
