After 3 full resets with the same issue each time (growing system data from 6gb up to 92g) I finally worked out that it was an issue with iCloud Photos. I always have it set to ‘optimise iPhone storage’ so I clicked download and keep originals and then back on optimise iPhone storage. And the issue has just disappeared. It seems the phone was holding on to 10 years of photos and videos and not firing them off to iCloud automatically as it usually does. Only downloading old photos etc as I require.
A bit of a headache for a week, waking up to iPhone storage full every morning.

Well I downloaded the Beta 2, and the whole day my System Data has stayed at 7-8gb

Which I think is fantastic, although the above photos remedy might be the key

Does anyone know how long Apple allow Beta 2 until you need to update?

I work Offshore and the Wi-Fi isn’t good, so I would have to hold onto Beta 2 till I got home

I may just revert back now if the photos works
 
Hey, looking for some support.

Received my iPhone 14 Pro Max 256gb yesterday and after 24 hours I’m getting the “iPhone storage full” notification which can’t be true as I’m using 80gb tops.

When I checked the storage in settings, looks like system data is maxing out.

I turned the phone on and off again and it dropped to around 4gb, but it’s growing consistently. After an hour it’s at 65gb, and it’s going to max out again for sure.

Anyone got the same issue? Annoyingly I can’t see what’s driving the usage, or what’s being cached. I have turned off sharing analytics etc, but it’s still building.

Is this a known bug with iOS

Is this a known bug with iOS 16?!
I had to do a factory reset while connected to a computer and then restore from the cloud after that and it worked. It seems to be the only way to deleted the system data. Mine was at 160gb. I originally set up the new phone from the cloud and this seems to be what’s screwing everything up. Once I reset to factory seatings while connected to my computer and then restored from my last back up, my system data is now at only 4gb

I restored the phone back to factory settings while connected to my computer. Then I restored from my last back from the cloud and this worked completely. Originally I set up my phone out of the box directly from the cloud and this gave me 160gb of system data on my iphone 14pro 256 gb. Now I only have 4gb.

I don’t have a computer back up so really hope there’s a fix soon from Apple.
 
The phone restarted itself after a few minutes and the data dropped to 5Gb. We'll see in the morning. (I'm from Czech Republic)

Thought I would chime in and share my experience so far. iPhone 14 Pro 256 gb picked up Friday. Discovered the bug on Sunday when trying to take photos in the mountains and storage was full (approx 195gb of system data).

Contacted apple support, first try was a factory reset with Mac and restore from iCloud backup. That didn’t work. Back to support, escalated to senior advisor, who took a bunch of diagnostics and escalated to Engineering. He said it will likely get fixed in an update but couldn’t give a timeline. In the meantime he recommended I try factory reset and setup as a new phone rather than restore from backup. I haven’t done this yet. He did also say there was a chance it resolves on its own but he didn’t have much hope in that. Either way, I do believe Apple is aware of the issue, it’s just a matter of how widespread this is that’s going to determine its priority on the bug fixing list for engineering.

Tried deleting WhatsApp completely last night, worked for about 12 hours, this morning system data was around 2gb. Later this morning started climbing and my storage is already maxed again now.

Turning phone off and on again does reset the system data.

Update on my experience, possibly solved. Last night I noticed a few apps never downloaded back to my phone when I setup my new phone from iCloud backup. They couldn’t download because the apps don’t exist anymore, but they still showed up on my storage list, with a cloud icon + down arrow. So I deleted those apps, restarted the phone, and system data appears stable. Been on wifi and 5G since. Been almost 24 hours. Might be jumping the gun to say it’s fixed but who knows!
 
Good morning from the center of Europe. After the update and spontaneous restart, the data is at 5Gb and still holds. A nice change in the morning. I hope it lasts. Now, however, purchased movies cannot be downloaded from the cloud.

That seems to have worked for me! So far so good!
 
Currently Fri morning and system data still at:

Just updated to official 16.0.2, hasn’t fixed the problem on my phone. Decision made, I’m returning phone as I’m still in 14 day return window..:/

I wasn't seeing much difference after 16.0.2 last night. So I decided to do another reset and set up as a new phone and finally it's stop growing. Won't go beyond 5GB now.
 
16.0.2 didn’t work for me either, I think I will just return the phone and try again in a couple ohms months, hope you all get it sorted.

I had my phone unattached to Wi-Fi for 48hrs (been working and moving around from location to location), and turned off the sync iCloud over mobile data setting (to save usage). Bizarrely system data then didn’t move…

Back on Wi-Fi. Bang. 100gb.

Clearly this bug is an iCloud syncing issue.
