I've been reading how the new Samsung Galaxy 8 phone has an "always on" OLED screen. Which basically means it can show a very limited amount of info on screen (like the time) at all times. Your screen never is completely black. They've apparently got the tech so that it uses only around 1% of battery life to have this feature enabled.
I'd love for Apple to use this tech in any new Apple Watch. Imagine the face of the watch could always be on. No having to raise wrist to see it. I've always thought an Apple Watch with the face visible is very beautiful, but with just the blank black screen, looks rather ugly. And most people only see the blank screen while you're wearing it so it's not very fashionable compared to real watches. The always on screen though could be game changer.
