How To Fix Error Installing iOS 16?

Error Installing iOS 16

The latest iOS 16 is available for users to download to their compatible iPhones. However, as beneficial as this new iOS update is, several users have complained that they have experienced errors while trying to download and install the iOS 16 to their devices.

But, why does it happen? Why are you experiencing errors while trying to download the latest iOS 16 update?

This article will walk you through all the potential reasons and what you can do to fix the errors that are popping up.

What are the Requirements to Install iOS 16?

iOS 16 has introduced a barrage of the latest features and updates. Some are pretty new and exclusive while a few others include an upgrade from the previous version.

If you are considering updating your iPhone to the latest iOS 16, keeping a check on these requirements is quintessential.

The following are the factors you will need:

Compatible iPhone – Apple provides access to the latest iOS updates for up to 5 years or so. This means that if you are using an older iPhone like iPhone 6 or 7, you won’t be able to install the latest iOS 16 to your device. So, ensuring that your iPhone is compatible is crucial before you start the installation process.

Battery percentage – Software updates will drain your battery significantly. Since some software updates can take time, the last thing you want is for the battery in your device to run out and interrupt the iOS update in the middle. So, ensure that your iPhone has at least 50% battery.

Stable Wi-Fi connection – A stable internet connection is mandatory. You can’t download a big iOS update if your internet isn’t stable. So, check the network before starting the installation.

Free storage – Most iOS updates, including the iOS 16 update, require your device to have sufficient free storage. The update won’t install if you don’t have the required storage in your iPhone.

Server complications – Apple has millions of users that are simultaneously trying to update their iPhones to the latest iOS 16 update. If you experience errors with the update, be assured that it could be a temporary issue with the server.

With the requirements out of the way, let us now shift our focus to some of the fixes you are trying to streamline the download process of the iOS 16 to your iPhone.

How to Fix iOS 16 Not Installing on iPhone?

If you have sorted out the essentials as we mentioned in the previous section, you are ready to move on to implementing the fixes. Technically, they work pretty well and should allow you to sort things out in no time at all.

Following are some of the fixes you are checking out:

1.      Force quit the Settings app

Sometimes, the main reason you aren’t able to download and install your iOS 16 to your iPhone is due to a temporary glitch in the Settings app. It happens a lot more than you’d like to witness.

Here’s what you need to do:

  • Swipe up from the bottom-left corner of the display and hold it. This will open all the background apps.
  • Drag the Settings app card to the force quit option.

Once done, follow Settings > General > Software Update and start the download and installation process again. If it doesn’t work then, you’d need to work again.

2.      Restart your iPhone

Another way you can fix the issue of not being able to install iOS 16 is by restarting your iPhone. The process is fairly simple.

If you have the newer iPhone models, here’s what you need to do:

  • Press the Volume down button and release it.
  • Press the Volume up button and release it.
  • Long-press the side button until the slider appears on the screen.
  • Drag the slider to turn off the iPhone.
  • Wait for a few minutes and then restart your iPhone again.

Restarting your iPhone works as a reboot and allows you to fix the temporary glitches or bugs that could be preventing you from downloading the iOS 16 update.

3.      Free up Storage

We discussed this briefly in a previous section of the article. Sometimes, the main reason you aren’t able to install iOS 16 on your device is due to a lack of storage.

Explore Settings > General > iPhone Storage to check how much free storage you have. If you don’t have as much storage as needed for the iOS update, it will prevent you from downloading the update.

So, find out ways to clear out the storage. You can also transfer your files to iCloud to free up some storage.

4.      Delete the Downloaded firmware

If your iOS 16 update has been interrupted and you have managed to only download a section of the update, the next thing you need to do is go ahead and delete the downloaded firmware.

There could be multiple reasons interrupting your firmware update, including insufficient space, poor network conditions, etc.

Follow Settings > General > iPhone/iPad Storage > Click Delete Update for the downloaded file. Doing so enables you to work with a black canvas and re-download the firmware from scratch.

5.      Update via iTunes

Unless you have been using iPhones for a long time, chances are that you might not be aware of this. If all the above-mentioned methods don’t work out for you, the last option is to update via iTunes.

It works effortlessly and enables you to update your iPhone to the latest iOS 16 update version. Here’s what you need to do:

  • Download and then install the latest iTunes to your computer.
  • Launch the installed iTunes and then plug in your iPhone.
  • Follow the Device tab > Summary > Click Check for Update.

If the iOS 16 update is available, you should be able to download and install it directly from there to your iPhone.


And, that concludes our list of fixes you can try if you aren’t able to download and install your iOS 16 to your iPhone. Identifying what’s causing the issue is crucial if you want to fix the problem in the first place. We hope this article gives you all the insights you were in need.
