How to Update Your iPhone (And When to Wait)
Software updates fix bugs, patch security holes, and sometimes add features. Here's how to update safely and when to hold off.
Quick path
Plug into a charger. Connect to Wi-Fi. Open Settings > General > Software Update. Tap Download and Install. Walk away for 30-60 minutes. iPhone restarts itself when done.
Before you start: back up
Updates almost never lose data, but back up first as a precaution. Settings > Apple Account > iCloud > iCloud Backup > Back Up Now. Or plug into a Mac/PC for a computer backup.
Update steps
- Plug into a charger
- Connect to Wi-Fi (not cellular for large updates)
- Open Settings > General > Software Update
- If an update is available, tap Download and Install
- Enter your passcode if prompted
- Agree to terms
- Wait. The iPhone will restart itself once or twice during the process.
Point updates vs major updates
Point updates are small (like iOS 17.4.1 to 17.4.2). Mostly bug fixes and security patches. Install these soon.
Major updates are big (like iOS 17 to iOS 18). New features, new design, sometimes bugs. Wait 1-2 weeks for Apple to release a quick follow-up that fixes early issues.
Common problems
- "Unable to verify update": Wi-Fi disconnected mid-check. Restart router, try again.
- "Not enough storage": clear at least 5 GB. Settings > General > iPhone Storage > Recommendations.
- Stuck on Apple logo for hours: force restart (Volume Up, Volume Down, hold Side button).
- Update keeps failing: plug into a computer and update through Finder (Mac) or iTunes (Windows).
If your iPhone is too old to update
Apple supports iPhones with major iOS updates for about 6 years. If your iPhone is older, you'll stay on a previous iOS. You can still get security updates for a couple more years past that. Beyond that, time to upgrade.
