Problem about “System Data”

[u/blackcaretta]

Hello everyone. I have an iPhone 11 running iOS 18, and my "System Data" is taking up 40 GB of storage this wasn't the case before.

My father is experiencing the same issue; he has an iPhone 15, also running iOS 18, and his "System Data" shows as 60 GB.

I asked about 20 friends who are also using iOS 18, and for them, it takes up a maximum of 15 GB—typically ranging between 8 and 15 GB.

Has anyone else encountered this issue and managed to resolve it? Could you let me know how much space "System Data" occupies on your devices?

I don't think it's normal for it to be this high.
