iOS update fails because your iPhone doesn't have enough storage
Your iPhone needs 2-3GB of free space to update iOS, not including the update file itself. Delete old videos and unused apps, then try updating again. Once the update finishes, you'll have more free space than before.
iOS updates are large. Several gigabytes. And your iPhone needs not just space for the file, but extra temporary space to prepare the system. It's like needing space on a shelf to rearrange books before putting them back. When storage is nearly full, there's no room for the temporary files. The good news: once the update completes, you'll actually have more space available.
- ✓Check your current storage: Go to Settings → General → iPhone Storage and note how many GB are free
- ✓Make sure you have at least one app or video you're willing to delete to free space
- ✓Keep your iPhone plugged into power during the update once you've freed space

Skip, I just want a technicianCommon mistakes to avoid
- Deleting important data aggressively when focusing on videos would be safer
- Not deleting enough before retrying update. Need to get to 2-3GB minimum
- Deleting system files trying to free space. Don't delete anything you're unsure about
- Trying to update over cellular when WiFi would be more reliable
