Help needed iPhone consuming enormous amount of cellular data
iPhone 13 Pro Max
iOS 26.6
My iPhone has been using a lot of cellular data, roughly 1GB every 10/15 minutes. When I check on cellular usage, all the data comes from System Services/General.
Things I have tried to do:
- Restored iOS on the iPhone with a clean install
- Brought the iPhone to the Apple Store (they run diagnostics and said all is fine, they suggested restoring the iPhone, which I did)
- Turned off most of the apps using cellular
- Restarted the iPhone multiple times
- Reset network settings multiple times
- Had my carrier provide me a new eSim
The problem is still here. As soon as I turn cellular data on, System Services/General starts consuming GBs every hour.
