Storage shows that System takes about 12 Gb of storage.
Anyone else have System taking up 12 GB after installing, and know how to fix it?
Edit: storage taken up by system keeps rising. Reaching 13 GB.
Restart didn't help.
Pretty simple triage - the “system” either now contains an iOS update cached or a lot of user data, but you can convince yourself:
Measure the space. If you feel it’s still taking a lot of space, put the device in recovery mode and restore it.
Once you’re OK with the space usage of the bare system, erase one more time and restore from your backup of choice or just sign in and set it up new if you want to start fresh.
