If you’re using an older iPhone like the XR, 11, or SE and recently upgraded to iOS 18, you might notice the system now handles updates more automatically than before. Apple has made it easier to stay secure and up to date — here’s how it works and how you can manage it.
1. What Automatic Updates Do
Automatic updates ensure your iPhone installs the latest iOS 18 security patches and bug fixes overnight while charging and connected to Wi-Fi.
This helps keep older iPhones optimized and protected without requiring manual downloads.
2. Check If Automatic Updates Are Enabled
Go to Settings → General → Software Update.
Tap Automatic Updates.
Make sure both options are on:
Download iOS Updates
Install iOS Updates
When both are active, your iPhone will automatically install new versions during idle hours.
3. Schedule or Pause Updates
If you prefer more control:
Toggle off Install iOS Updates to only download updates automatically, then install manually later.
Updates won’t install if your phone is low on battery or storage, so keep both in check.
You can also delay major version upgrades (like 18.1) while keeping security responses active.
4. Enable Rapid Security Responses
Apple now delivers smaller, faster patches between full updates.
Go to Settings → General → Software Update → Automatic Updates.
Turn on Security Responses & System Files.
These install silently and won’t require a full reboot.
5. Troubleshooting Auto Updates
If your older iPhone isn’t updating automatically:
Ensure it’s plugged in, on Wi-Fi, and locked overnight.
Disable Low Power Mode, as it can pause background tasks.
Check available storage space — at least 5 GB is recommended.
Restart your device, then revisit Software Update to trigger a manual check.
AvNexo Tip
Even on older models, automatic iOS 18 updates help extend your phone’s lifespan and security. Keep them on to avoid missing vital fixes — but if you prefer full control, set reminders to check for updates manually every few weeks.
