Thank you for the screenshot.

Updating your iPhone:

Seems you're having WiFi issues. So, having an iPhone 13 Pro with iOS 15, try either of the follwing

• Cellular:

Use my User Tip: Use an iPhone 12 or later, that is using 5G, in order to update over Cellular - User Tip

• Computer:

Use my User Tip:  Update your iPhone Using a Computer - User Tip

Back Up First:

IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update
