If you’re facing a persistent error that prevents your iPhone from updating, it’s possible that there’s a deeper system issue.

Reinstalling the iOS Update

Sometimes, the best way forward is to start afresh. To do this:

  • Navigate to ‘Settings’ > ‘General’ > ‘iPhone Storage’ on your device.
  • Locate the iOS 16 update, tap it, and select ‘Delete Update’.
  • Head back to ‘Settings’ > ‘General’ > ‘Software Update’ and redownload iOS 16.

Verifying Network Settings

A glitch in your network settings could be the source of the “update cannot be installed” error. If so, confirm that your cellular network is active and, if needed, reset your network settings within the ‘Reset’ tab under ‘Settings’ > ‘General’.

Updating iOS via iTunes

Utilizing iTunes is an alternative route to update your iPhone:

  • Open iTunes and connect your iPhone. Select your device, navigate to the ‘Summary’ tab, and click ‘Check for Update’ followed by ‘Download and Update’.

Turning Off Low Power Mode

If restarting your device doesn’t solve the issue, disabling Low Power Mode might do the trick. Do this, then restart your device once more.

Checking iPhone Storage

Lack of storage can prevent an iOS update. Free up some space by going to ‘Settings’ > ‘General’ > ‘iPhone Storage’ and manage your storage accordingly.
