It's a bizarre page really, the entire top section is:
> 6.5" / 6.9"
[Makes sense so far.]
> Super Retina XDR display1
They're proud of the resolution, whatever it actually is, though only know that because they've used 'retina' for years, and Super & XDR sound high tech and better.
> ProMotion technology
Maybe something to do with motion blur of videos?
> Always-On display
That sounds... Undesirable? But presumably it must just mean it's faster to wake up or something?
> Dynamic Island
Absolutely no idea.
As for the others:
> Always-on Display: The display will show the current time when the phone is sleeping - it uses less power than it would on an LCD phone because of OLED.
> ProMotion: 120 Hz refresh rate, but only when Low Power Mode is off and the app requests it (e.g. games). So basically VRR (in fact, it is actually VRR under the hood)
World's best unitasker.
