1. Check compatibility before updating

The primary step before proceeding is to ensure whether your Apple Watch officially supports watchOS 9 or not. If you rock an Apple Watch Series 4, Series 5, Series 6, Series 7, and SE, you can update to the latest OS.

The latest Apple Watch Series 8, SE 2, and Apple Watch Ultra will come preinstalled with watchOS 9. But if you have trouble installing the next version of watchOS 9, this guide will be helpful for that as well.

2. Perform the basic checks

Now, before we advance further, it is essential to satisfy some conditions.

  • Update your iPhone to ensure perfect harmony.
  • Your Apple Watch battery must be at least 50%.
  • Connect your iPhone and watch to a stable Wi-Fi. If your net is too slow, consider restarting the router. Also, do not forget to disable the VPN.
  • Make sure Bluetooth is enabled.

3. Retry updating after restarting the Apple Watch and iPhone

In multiple posts, we often mention that restarting is one of the easiest and (an almost) sure shot ways to fix several software issues.

To restart your Apple Watch, press the Side button and drag the Power Off slider to the right. After a minute, press the same button to turn it on. To restart the paired iPhone, use the power button as you usually do.

After this, try to update the wearable. You can do so straight from the Settings app on the Apple Watch or use the Watch app on the companion iPhone.

4. Free up space on your Apple Watch

Just like you must have a certain amount of free space for updating the iPhone, your Watch too follows the same rule. If you cannot install watchOS 9, which is a major generational update, consider freeing up some space. Once you do that, restart the devices and try updating them again.

5. Delete the update file and retry

  1. Open the Watch app on the paired iPhone and ensure you are in the My Watch tab.
  2. Tap on GeneralStorageSoftware Update and delete the downloaded update file.
