User level: Level 1 (4 points)My 128 GB iPhone 13 System Data is at 67.5 GB. Every time I delete photos, apps, or messages, the System Data increases the next day and I’m back at 127.8 GB.
I can no longer send or receive texts, I can’t use apps, and my phone freezes. My phone is unusable at this point and I am unable to fix it. When I clear storage, it fills immediately with System Data. Anyone know how to fix this?

You likely have some corrupt data in your System Data. Typically, System data fluctuates depending on need and we users don't need to worry about it. But sometimes something goes wrong and there is no way to get into what is actually stored in System Data. So the best way to reduce it is to backup your iPhone, then restore your iPhone from backup.
