And a serviceable refurbished iPhone isn't that much more, e.g. https://swappa.com/listings/apple-iphone-se-2nd-gen?carrier=...

ok, but could that mean many people that are assumed to have new devices could actually be using older devices?

		Probably. The iPhone users I know mostly replace their phones once every 3 to 5 years, and they don't all buy brand new replacements even then (although some do.)
