Hello
My System services, specifically security services has started burning through my cellular data on iOS 14.4.1 and now 14.4.2. Please, what can I do to stop it?
Tried factory reset today, did not help.
Got the exact same issue. Seems that Security services is gobbling insane about of data. I've captured the data being sent over the cell network (everything is secured using TLS 1.2 or 1.3) but end up on the 17.0.0.0/8 subnet. So it's data sent back and forth with Apple owned Services, and cannot be controlled by the user (or it's background tasks that is doing this).
Because of the secure nature of the network traffic, it's hard to guesswork what it being used and the logs don't seem to give any insights. However, one thing is for sure, it's something tied to the AppleID. One thing worth mentioning, this network traffic is also happening on Wi-Fi but since most Wi-Fi access are unlimited or with high caps, it's not noticeable. But turning off data and only using Wi-Fi showed the same odd traffic pattern. The fact it's happening on cell network is just more observable.
I've logged out of my AppleID on my device, restarted it (shutdown and cold boot) and there is no further traffic (or very little)
Opened up a case and entered a bug report on the dev website, but so far, very little seems to be known about this right now. I'm somehow happy to see I'm not insane and not the only one having issues like this, and moreover happening on various carriers (even more intriguing)
Would be nice to see if those affected are using family sharing feature or not.
Cannot even book a session. My phone is out of warranty. Did you have a better luck?
Just tried it. Did not help
Thank you for the update Marc. I’ll try to logout of the appleid. I’m not using any family sharing features.
I just opened a case today. My call got escalated to second level as all the details were clear and it's to a referenced issue yet.
I will let you know.
This is from this morning. It took 28 minutes to upload 2GB of data over cellular.
Great detective work! If you have a developer ID file a bug report.
Amazing, I'm going to try this today!
Interestingly, when I try to disable keychain sync on my iPhone, it asks for my password but then stay enabled whatever I'm doing.
I tried everything. I cannot disable keychain.
And support is not calling me anymore.
I have a gsuite email account, yes.
i just removed it but it does not change anything so far.
i have no mdm
During few hours, no consumption made by security services and then 1.5gb of data used.
so i am back at the same state than initially.
Keychain is the app that fills in your password automatically when you log in to an app or website. If you turn it on in iCloud it will sync your passwords across all of your devices.
Why can’t you turn off Keychain?
I have tried many times, it just doesn’t turn off, it cannot be turned off.
I have tried many times, it just doesn’t turn off, it cannot be turned off. There is no change in the state or it doesn’t show a change and turns on right back.
Yes, this did it for me. Data traffic is normal again.
I have not turned on keychain synching yet, though. Pondering if I can wait for a software update before doing that.
Thanks!
