System data on iPhone is huge?

This issue was recently reported by Kai (iOS 16.2):

“System data in iPhone storage occupies almost 100GB. Is there any way to delete it?”

Other system data taking up too much space is nothing new. We covered the same issue in the early stages of iOS 15.

It seems to have carried over to iOS 16 and many users are complaining about it on Reddit (1,2,3) and Apple’s message boards (1 and 2).

Other system data Zero KB?

Some users also see system data displayed -1 byte or Zero KB. This unexpected behavior is currently happening on my iPhone 13 Pro as of this writing.

In this case, there is a spinning wheel next to System datain Settings -> General -> iPhone Storage (scroll down to System Data).

If the wheel is spinning and you press System Data, you’ll see Other system data -1 byte. If you wait long enough for the loading wheel to disappear, you will get Other system data Zero KB.
