In order to install iOS 16 you should remove any beta profiles from your iPhone. Do so via settings>general>VPN and device management>iOS beta software>tap remove beta profile

Now that is out of the way: update via settings>general>software update. The iPhone needs to be on WIFI for the XS max and low power mode needs to be turned off. Place the phone on the charger when updating
