Why is ‘General” under ’System Services’ using excessive cellular data?

I’m using iPhone 15ProMax at iOS 18.3.2 on Roaming, and System Service General eats up over 5GB of roaming data. Tried the support app, it’s just recommend update to 18.4

i have updated and the problem still persist.

Same problem with iOS 9 user decades ago, and here we are facing the same problem in 2025


at 18.3.2(Roaming) eats up half of my 10GB plan




At 18.4 eats up over 700MB over 1.1GB

what is this general system doing. It does not behave that way in my wife’s phone.

After hours of desperation and research, i THINK i’ve found the problem. Navigate to Settings > Apps > and check each and every app you don’t use and manually turn off “cellular data”. I’ve noticed “App store” automatic updates and cellular data were on although i have it off in “cellular data” and there are a TON of default apps we never use but are built-in and they ALL had cellular data ON. When I turned all of them off the “General” section disappeared from System services. I hope this was the problem!

if I restart my phone while out of wifi coverage, the 1Gb of data disappears rapidly (within minutes) and the culprit is System Services/General.

Or the culprit is your provider, indicated and measured by Systems Serviced, General

I strongly recommend anyone with this problem to get a hold of a monthly rolling cellular plan and test it for a week. Divert your calls to the new number then take off the current plan fir the test.

I really do think I have fixed the issue now. I still don’t know what was causing the problem.

My fix was rather drastic - I erased my phone and did not restore from a backup. I took screenshots of the apps etc and only reinstalled those that I absolutely “had” to have. It’s surprising how few of the apps that I used to have on my phone I actually need!

Everything seems to be working just fine at the moment.

My cell phone plan has just renewed, so now I have more data to experiment with to see if I can find a cause for the data drain that I have.

All I have come up with so far is that if I restart my phone while out of wifi coverage, the 1Gb of data disappears rapidly (within minutes) and the culprit is System Services/General.

If I don’t restart my phone while out of wifi coverage, then everything seems to be fine and my data doesn’t disappear.

I have been dealing with this for over a year. I had just resigned to keeping cell data off. In some occasions where I need to turn data on, my phone just likes to consume 200-300mb in general for no reason. It usually happens within an hour.


i use DataMan so I can tell where it happens. I just have no idea what causes the issue. Had looked for a vpn that would log ip addresses and data amounts to see if I could find out what site is being contacted for the transfer. But could not find a suitable one. I’m not even sure it would log this anyway.


I have a new 16e since earlier this year and it is not any better over my se3. Am thinking I will erase and start fresh.


i called Apple once early on. The tech on the phone said that they (Apple tech support) have no idea what general means! They said the developers do not tell them. I found this infuriating. At least tell me what it is you are doing that’s so important you can’t wait for a WiFi connection!


My shared data plan is via xfinity so each extra gig costs $20. I suspect this bug has cost me at least $300.


I would love to have Apple tell us what consumes this data.
