There are different ways to ensure the highest iOS that your device will support is installed on your device.

This support article has instructions about updating an iPhone or iPad wirelessly --> Update your iPhone or iPad - Apple Support

You can also use Mac and PC computers to update system software:

If your Apple mobile device won't update, read this support article --> If your iPhone or iPad won't update - Apple Support

Another, less common reason for not being able to update is if you were using a beta version of software. Refer to How to uninstall iOS or iPadOS beta software - Apple Support

Hi!

To upgrade your iPhone X to the latest version of iOS, you can do this wirelessly or via a computer. To update wirelessly, go to Settings > General, then tap Software Update. If you have multiple software update options, choose the one you want to install and tap Install Now.

If the update does not appear on your device, you can use your computer to update it manually via iTunes or the Finder. Connect your iPhone to your computer using a Lightning/USB cable and open iTunes or the Finder. Click the smartphone icon on the left and then click the Check for Updates button. When iOS 16 is detected, press the Download and Update button.

I hope I helped you!
