Quick Fixes

1. Free Up Storage

Settings > General > iPhone Storage. Need 5-10GB free for major updates. Delete apps/photos.

2. Check WiFi Connection

Need stable WiFi. Restart router, move closer, or try different network.

3. Delete and Re-download Update

Settings > General > iPhone Storage > iOS Update > Delete. Then re-download fresh.

4. Charge iPhone

Need 50%+ battery or plugged in. Connect to charger during update.

5. Restart iPhone

Force restart: Volume Up, Down, hold Side. Then try updating again.

6. Update via Computer

Connect to Mac/PC. iTunes/Finder > Check for Update > Download and Update. More reliable.

7. Check Apple Servers

Visit apple.com/support/systemstatus. If servers down, wait and retry later.

8. Disable VPN

Settings > VPN > OFF. VPN interferes with update downloads.

9. Reset Network Settings

Settings > General > Transfer or Reset > Reset > Reset Network Settings.

10. Recovery Mode Update

Last resort. Connect to computer, enter Recovery Mode, select Update (preserves data).

Conclusion

Most update failures due to insufficient storage or poor WiFi. Free up 10GB space and use stable WiFi for best results. Update via computer if over-the-air fails.
