iPhone System Data Taking Too Much Storage (Fix It)
⚠️ Immediate Fix
"iPhone Storage Full" alert but no photos? "System Data" (Other) is bloating your drive. This is a logging bug. Connect your iPhone to a computer and sync with iTunes/Finder. This forces the OS to recalculate logs and flush the temporary cache instantly.

Why This Happens
- Phantom Logs: Failed syncs leave invisible files.
- Streaming Cache: Spotify/Netlfix buffers not clearing.
- Update Files: Old iOS installers hiding in system.
Step-by-Step Fix
- iTunes/Finder Sync (Best Fix): Plug into a PC or Mac. Open iTunes/Finder. Let it sync. The computer analyzes the storage map and deletes "orphan" files.
- Change Date Trick: Change Date & Time to 1 year in the future. Wait 60 seconds. Change it back. This sometimes forces a system cleanup.
- Offload Unused Apps: Go to Settings > App Store. Enable "Offload Unused Apps". This deletes the app binary but keeps your data.
- Erase All Content: If System Data is 80% of your drive, it's corrupt. Back up to iCloud, then Erase All Content and Settings. Restore from backup. This rebuilds the file system.

When to Stop
If you see "Error 14" or "Error 1110" when trying to update, your storage is critically full. Do NOT try to update again. You are at risk of a bootloop that can only be fixed by erasing all data.
