Here are a few fixes according to different reasons that may cause the iPhone won’t update issue. You may not have to try them all; just work your way down the list until you find the one that works for you.

Fix 1: Force restart your iPhone

If you’re installing the iOS update, you’ll see the process bar appear to move slowly. The time an update takes depends on the size of the update and the number of files on your iPhone.

If the update takes long time and never completes, and the process bar hasn’t moved for an extended time, try to force restart your iPhone.

Here’s how you can force restart your iPhone:

If you’re using an iPhone 8 or later: press and quickly release the Volume Up button, then press and quickly release the Volume Down button. After that, press and hold the Side button until you see the Apple logo.

If you’re using an iPhone 7 or iPhone 7 Plus: press and hold both the Volume Down and Side buttons for at least 10 seconds until you see the Apple logo.

If you’re using an iPhone 6s or earlier: press and hold both the Home and Top buttons for at least 10 seconds until you see the Apple logo.

Once you iPhone boot into iOS, try to install the update again to see if it completes successfully. If it get stuck again, you have something else to try…

Fix 2: Check if your iPhone has enough available storage space

The iOS update requires enough available storage space on your iPhone. That is to say, if your iPhone is lack of free storage space, it won’t update either.

Follow these steps to check if your iPhone has enough available space:

  1. Go to Settings on your iPhone.

  2. Tap General > About.
    You’ll then see how much free space is on your iPhone under Available.

If the free space on your iPhone is less than 1GB, we highly recommend making room for the update manually.

You can remove content those take up a large amount of space and apps that you don’t use.

Once you do, try to install the iOS update again to see if it goes well. If it fails still, don’t worry, move onto next fix.

Fix 3: Check the network connection on your iPhone

iOS update requires a network connection on your iPhone. The time it takes to download the update varies according to not only the size of the update, but also your Internet speed.

If the download takes long time, you’d better not download other content on your iPhone while downloading the iOS update. In addition, please connect your iPhone with a strong Wi-Fi network to improve the speed of the download.

If you’re sure the network is not to blame or the update keeps failing after your iPhone connects to a strong Wi-Fi connection, don’t give up hope, there’s other fix for you…

Fix 4: Update your iPhone with iTunes

If you try to update the iOS on your iPhone, but it fails, and you’re seeing the error message saying Unable to Check for Update or Unable to Verify Update, tap on Try Again or Retry to update your iPhone again. If it fails still, update your iPhone with iTunes instead of OTA(on-the-air) update.

  1. Install the latest version of iTunes on your computer. (Skip this step if there’s one on your computer.)
  2. Connect your iPhone to your computer.
  3. Open iTunes and select your iPhone.
  4. Click Summary, then click Check for Update.
  5. Click Download and Update.
  6. If asked, enter your password.
