If you have tried to update your device over the air to iOS 15 and the process has failed, there are several reasons why. The most common ones are a lack of adequate storage on the device, you are unable to reach the Apple servers or your device doesn't have enough power. Since these reasons are simple enough, the solutions are also quite simple as well. But sometimes, the update can be so problematic that no matter what you do you still can't update the device.

If your iOS 15/14/13 update doesn't complete for one reason or another, this article will offer you solutions that are tailor-made to help you fix the issue once and for all.

1. Basic Troubleshooting Options

Sometimes all your device needs is a little tweaking to get it to respond the way you want it to. The following are just some of the simplest troubleshooting steps you can take to try and get the iOS 15/14/13 update completed.

  • Check that you are connected to a strong enough Wi-Fi network. The simplest way to do so is to open a web page in Safari and see how long it takes to load. If you are not, choose another network.
  • Make sure that your device has adequate power. If not, connect the device to a power source before attempting to update.
  • Check to make sure that you have adequate storage space on the device to enable the update. You can delete some unnecessary files to make room.

2. Force Restart the iPhone

If you've done all the above and your update still won't complete, try forcing a restart. To do that, (for iPhone 7 and iPhone 7 Plus)hold down the Sleep/Wake button and the Volume until you see the Apple logo on the screen. (for iPhone 8 and later) Press and quickly release the Volume Up button and the Volume Down button.
Press and hold the Side button (aka power) until you see the Apple logo.


3. Try A Professional Software Tool (iOS 15/14/13 Supported)

If a forced restart fails to fix the problem, you may have a corrupt iOS firmware or the update itself might be corrupt. In this case, you may require the services of a Professional Software like iMyFone Fixppo to get the update working again. This program is designed to fix any iOS issue including and not limited to a device that is stuck in recovery mode, one that is stuck in DFU mode or a device that simply won't start.
