"Famously, the XS and XS Max (be sure to call them "Ten S" or an Apple representative will sidle up and correct you) share the same A12 Bionic chip as the XR."
What's famous about that? I'm not normally one to pick up on such grammatical superlativisms - but it seems a bit of a stretch to say anything of the sort. Fish and chips are famous. The Saturn V rocket boosters are famous too; as is the Titanic, and Alexander the Great. There is nothing famous about the iPhone whatsoever as far as I can tell.
That said, if Apple had wanted it to be called a "Ten S" then they should have called it a "Ten S". As is stands, it is an 'X' as in the 24th letter of the alphabet, an 8 point tile in Scrabble, or "10" written as a Roman numeral. And yes, I'll happily correct any Apple representatives that dare challenge me on it lol!!!
