System Services using all my data after iOS16 update

System services is constantly using my data when I'm not connected to Wi-Fi, I've had to add 2gb extra last night and I've now got 59mb's left. I've tried turning off automatic updates etc but nothing seems to be solving it. How do I stop this as I currently can't have data turned on, which is not great when not connected to Wi-Fi.

See screenshot of data used after literally 5 minutes after I reset the statistics.

iPhone 8 Plus, iOS 16

I actually said "System services is constantly using my DATA when I'm not connected to Wi-Fi, I've had to add 2gb extra last night and I've now got 59mb's left." The screenshots clearly show that system services is using a lot more data then it should be.

Again this has NOTHING to do with storage and is about Cellular data. It is an issue and if you've no idea on it then just say that, rather than saying there isn't an issue. For example my partners phone is currently on 1mb cellular data used for system services, mine is now showing at 750mb..

”Add”? It is not possible to add iPhone storage. You may add iCloud storage, which is completely different.

The amounts you’re showing on your screenshot are really minuscule compared to the total iPhone storage.


Here’s guidance regarding clearing your iPhone storage.

No sorry, this is not a storage issue, this is a cellular data issue.

Given you said this in your first post:

”I've had to add 2gb extra last night and I've now got 59mb's left.”

…and that statement has nothing to with cellular data, I actually have no idea what your issue might be.


But I do know that no screenshot you presented anywhere above presents any evidence of an issue.


You should check Settings > General > iPhone Storage and be certain you have no less than 6GB free at all times.
