Fortunately, I was able to figure it out, and now I can help the small percentage of users also experiencing this problem. Let’s take a look.

Why Won’t My iPhone Update to iOS 17?

There can be a number of reasons why you may be unable to upgrade your iPhone to iOS 17. Most likely, the issue can be insufficient storage, but smaller issues such as internet connectivity problems or small software bugs may also prevent an update. You also need to ensure your iPhone has the proper battery level. Fortunately, it’s easy to get your iOS 17 update working by exploring the solutions below. 

How Can I Fix iPhone Not Updating to iOS 17?

Before moving on, let’s take a look at some common reasons and solutions before diving into the more complex problems.

  • Check Compatibility: Your iPhone may have compatibility issues with iOS 17. Check device compatibility here.
  • Unstable internet connection: Ensure you have a proper Wi-Fi network or cellular connection. Ideally, Wi-Fi is better than cellular for software updates. Additionally, ensure that Airplane Mode is not active.
  • Force restart your iPhone: A simple restart may clear small bugs and errors. Go to Settings > General > Shut Down and then drag the Power Off slider to the right. You can turn your iPhone back on with the Power button.
  • Enable Automatic Update: Go to Settings > General > Software Update and ensure that Automatic Updates is turned on.
  • Check Apple Servers: Apple’s servers may be down. This one is typically unlikely, but it is possible. You can check Apple’s server status through its official page.
  • Check Battery: If your battery is less than 50 percent, you won’t be able to download the update. Charge your iPhone with a lightning cable or USB cable and try again.

If the above solutions didn’t help, consider the following viable solutions.

1. Free Up Storage Space

One of the common reasons you may not be able to install a major update is that you have insufficient storage on your iPhone. When making the update to iOS 17, you’ll want around 20 GB of free storage space. Fortunately, your iPhone can make recommendations on what to delete. Alternatively, we suggest using a practical cleaning app like Intego Washing Machine, as it gets rid of all caches, unnecessary files, and junk files almost instantly, saving a significant amount of space on your iPhone. If not, don’t worry, you can always follow the manual steps below.

Time needed: 5 minutes

If you’re using a Mac running macOS Catalina or later, you will be using a Finder window rather than iTunes.

If you’re still having issues accessing and installing the iOS 17 update, try using iTunes and/or Finder to install the update. Using a lightning cable or USB cable to plug directly into a desktop can give you a stronger connection to receive the update. 

  1. Connect your iPhone or iPad to your computer.
  2. Wait for your device to show up in iTunes or Finder.
  3. Once it presents itself, select Check for Update and follow the steps onscreen.
