iPhone X Excessive Data Usage

My cellular data usage has dropped significantly by disabling iCloud drive and the Photo Library from uploading via cellular data. Now they only upload when connected to WiFi. Problem was I recorded some videos while I was away from a WiFi and it uploaded the videos to the Photo Library over the cellular connection. I checked my data usage after I got an alert from VZ stating I had reached 90% and I saw huge data usage the same times I was recording videos.

There may be some other oddities like Safari using 50MB to do a search, but I haven't noticed that yet. For the first time since getting the iPhone X, I now have extra data to rollover into next month's usage.

I had the same issue since 2 days ago, after investigating on my iPhoneX i FOUND THE CULPRIT of both symptoms: iPhone getting hot and consuming data.

CULPRIT: Photos app, uploading items (photos & videos) to the cloud, even having previously UN AUTHORIZED the app to use cellular data to upload items.

For some reason this was changed, the app was re authorised to use cellular data, and it started uploading items.

The unexplained thing is why, even after uploading all my items to the cloud (more than 43.000), sometimes they must be uploaded again.

Still a mystery.

My problem is solved, i PAUSE the Photos app uploading of items while I am on cellular.

Finally found a solution at least for my setup. Battery and data drain was caused by faulty exchange server on our company site. Changing push to manual and everything finally came back to normal (30% battery a day usage and 10-20 MB).

I also installed 11.4.1 from scratch without restoring from backup.

Good luck all

One thing I've noticed since upgrading to iOS11 are Photos taking up a lot of data. Since photos and videos are no longer saved locally but on the iCloud, the device was uploading them all the time. The went for videos. So in either the photo or cellular settings, I turned off photos from using cellular data and only WiFi. That has seemed to help a great deal. Like you, the system settings still eat up data for some reason even though much of my time is spent on WiFi. Another thing I've noticed, and maybe it's always been this way and since I'm watching my data I notice it now, but iMessage is eating up a lot of data when sending pics or videos. Maybe because of the iPhone X's better camera (than my SE) and the photos are in higher resolution, more data is used.

I have a solution provided by Apple for the issue of iPhone X (IOS 11.3) iTunes Accounts in System Services using massive amounts of cellular data every 3 hours. The solution is to turn off "Settings:Music:Cellular Data". Also turn off "Settings:Music:Show Apple Music".

On my iPhone SE, iOS 11.4, I went to

Settings:iTunes & App Stores:Automatic Downloads

And turned off Music, Apps, Books & Audiotapes, Updates

At

Settings:iTunes & App Stores:

Use Cellular Data,

Video Autoplay and

Offload Unused Apps

are also now set to OFF

I now manually update apps and do updates when I’m not on a pay-per-MB connection.

Well i had the same issue.. the new update of instagram was chewing my data as well as Facebook. Turn iff autoplay videos in The app on Facebook and select ‘use less data’ to stop autoplay in Instagram ;)

I saw your post and checked my settings to see if I had an issue there as I'm finding cellular use higher than normal for me, regardless of all else I've done although those steps helped too, just not to the degree I'm used to. I just went into the YouTube app itself and turned off my data usage for it as well as limiting high data usage unless on WiFi. Going to be doing this for a few other apps on both of my phones. I had done this under cellular settings but as is fairly common for me, I got lax after updates to not only the phones but after updates to the apps as well. Many apps will default back to cellular after they update, so this is a nice and necessary reminder. Thank you for adding this to the post ~

Hi

Go to settings down to apps disable using cellular data on all the apps you don't need to use cellular data.

Then they will just work on wifi.

Go to i books download ios 11 user guide & iPhone X guide both are free.

System services should be about 4g.

Go to iCloud make sure iCloud back up is on Then backup now over your wifi.

Then go to settings down to reset Restore iPhone back to factory settings

Set back up over your wifi when it asks if you want to use iCloud backup Say yes to get your apps and data back this will get rid of any bugs.

Later go to books download ios 11 user guide & iPhone X guide both are free.

Cheers

As you can see I think I may have found the problem!!! because my data has went up I used 120gb’s in 1 day and was dumbfounded. until I looked up what was going on then decided to check my settings because there weren’t any answers. I found some apps like my apps store is using hundreds of gb’s of data from just running in the background

Location services was eating mine up. I disabled them. Huge improvement

Turned off data roaming and background refresh too

Hi emmicee,

I also turned off the majority of my location services that were always running too, which helped when I experienced this issue.

That may help also

I too have the same issue. I tried 3 geniuses in 2 stores, called multiple times, reset the phone in all kinds of ways, and changed my apple ID to a new one after a factory reset. None of this works. I honestly thought that new ID would do it but nope. "Apple ID Services" takes up cellular data even when wifi is ON and the phone is not doing anything. Say goodbye to 300mb of data while you sleep with all apps turned off and with wifi on. The only workaround is to have the cellular data turned off at all times. This has been happening to me for about 3 months or since the release of iOS 11. Prior to the forced update, I never had this issue. Even though I have 0 control over this (meaning, I can't turn off "Apple ID Services" like I can with apps) and paying for data I am not using, Apple obviously has bigger problems and won't even let me downgrade to iOS 10 which actually works.

Had the same problem with my new X, as told by my other posts here. Solved by going to Cellular screen and turning off WiFi Assist, Data Roaming, iCloud Drive. After that, reset your stats and monitor which apps are hogging data and switch them off too if you don’t need them while out and about.

Mine was eating up cellular while I was home in WiFi. Turning off these switches did the trick for me. My hog was Youtube. Seems videos on the X are heavy users. Some say due to the new screen resolution. Others say that’s bull.
