What to do if your iPhone won’t turn on after the iOS 16.6 update

Uh oh, you’ve just updated your iPhone to iOS 16.6 and now it won’t turn on! Don’t panic. This is a common issue that can often be fixed with a few simple troubleshooting steps.

iPhone Won’t Turn On After The iOS 16.6 Update

Force Restart Your iPhone

The first thing to try is force restarting your iPhone. This refreshes the device and reloads the operating system.

  1. Quickly press and release the Volume Up button.
  2. Immediately press and release the Volume Down button.
  3. Finally, press and hold the Side button until you see the Apple logo appear on the screen.

Keep holding the Side button until you see the Apple logo. This may take up to 30 seconds.

Forcing a restart usually fixes any software glitches and gets the iPhone running again. Try it a few times if it doesn’t work the first time.

Charge Your iPhone and Try Again

If force restarting didn’t work, the issue could be a drained battery. Here’s what to do:

  1. Connect your iPhone to the charger using the original cable.
  2. Leave it charging for at least 10 minutes, even if it doesn’t show the charging symbol.
  3. After 10 minutes, force restart the iPhone again using the steps above.

Charging gives the iPhone enough power to reboot properly. The force restart after charging should get the device back up and running.

Update or Restore with iTunes

If you still can’t get your iPhone to turn on, you may need to update or restore it using iTunes on a computer.

  • To update, connect the iPhone to your computer while holding the Home button. iTunes will detect the device in recovery mode and prompt you to update.
  • For a restore, connect the iPhone and choose the Restore option in iTunes. This will wipe the device and install a clean version of iOS. Make sure to backup your data first!

Updating or restoring through iTunes should resolve any software issues causing the startup problem.

Contact Apple Support

If you’ve tried all the troubleshooting steps and your iPhone still won’t turn on, your last resort is to contact Apple support. Call them or book an appointment at an Apple store for further assistance. Be prepared to restore or even replace the device if there is underlying hardware damage.
