It’s something I easily notice and it just makes the phone feel faster and more responsive, such as when scrolling on the web, swapping between apps, etc. Whenever I go back to a 60Hz phone I find the experience jarring and a step back. I imagine a lot of others feel the same way. Android phones cheaper than the SE have 120Hz displays so there really is no excuse at this point not to include it.I think I have fairly observant vision (I do a lot of photography and the Soap Opera Effect on cheap TVs drives me absolutely insane) but I can't see any difference between a 60Hz or 120Hz display. Perhaps I could discern a difference side by side but it's not a feature I care about at all.
My professional camera has an optional high refresh rate toggle for its electronic viewfinder, and I *can* notice a *slight* difference if I turn it on *IF* I'm photographing very high speed objects (sports, birds in flight, etc.) but it's very subtle. I don't see how this is a big deal for people, and considering the hit to battery life, I would prefer a 60Hz screen. Maybe if you are doing hardcore gaming or something on your phone it makes a difference?
How is this an issue for web browsing, texting, or reading?
It *IS* the type of thing I see Android fanboys always measurbating about, along with things like how fast their phone charges (again, I prefer the slower charge which preserves battery life, and I only charge my phone overnight anyway).
Also, ProMotion displays like those in the iPhone dynamically go down to 1Hz so any effect on battery life should be minimal.
