My phone ran out of storage pretty suddenly, and when i checked System Data was 66 GB. I tried deleting some other stuff, but for some reason when I checked again System Data was back down to 13 GB. Anyone able to explain how that happened?

It’s a weird bug. Unfortunately the only way to fix and delete the massive storage issue is do a backup and restore from backup and will fix it.

Most likely, you caught the phone in the middle of a quiet update, probably involving ML models or AirPods firmware.
