Original Title: Why is system data is 20Gb after ios 26 before it was around 10gb (iphone 15)
iPhone 15, iOS 26
I’m at 96GB. My culprit is wallpapers and lock screens. I could use up all remaining memory in less than an hour with one of my lock/Home Screen switching shortcuts. Kind of like a Home Screen slideshow.
Do you mess around with wallpapers much? Any focus mode or shortcuts that change wallpapers more than a few times a day?
if this is your issue, I’ve tried every “trick” I’ve come across to reduce this particular bloat in System Data. The only thing that works is backup, reset, restore. Some system updates clear it also, basically a partial reset. 26.0 and 26.1Beta did. I heard 26.0.1 did also.
if it’s something else, you could try the System Time trick or the ProRes trick (if you have a 15-17 pro model). Apparently those work for some people to clear quite a bit off.

Tap on System Data for an explanation of what it includes. Mine was 38 GB and dropped to 24 GB after updating.
I think this is not normal. It takes up all the free memory on my iPhone and gets bigger when I delete something to free up memory. And iPhone warns me that I'm running out of memory.

Mine ia 17.5 GB.
Same here! It’s 200GB of system data!! I already tried all the tips mentioned, like offloading apps, deleting and reinstalling etc. but its not helping😭
