Reply to comment by Venilix in I've just picked up an iPhone 14 Pro, with my last iPhone being an iPhone 4 (2011) - My Thoughts. by tomj1991

The scroll is primarily the issue here, almost all other animations are solid smoothness. General scroll in every first party app, such as settings, iMessage, photos, mail, safari, etc jumps to about 80-90hz. Pretty much all 3rd party apps that use the same default scroll api also don’t reach 120hz. Lastly, switching between home screen pages isn’t 120hz. Here are some apps that do, somehow, use 120hz scroll: telegram, Amazon, chrome. If you wanna see comparison to how it should be in 1st party apps, turn on screen recording and try scrolling while the screen is being recorded, that forces 120hz everywhere. See if you can spot a difference. Also, without turning on screen recording, see if you can spot a difference scrolling through a google search in safari vs chrome

I followed this test and noticed absolutely no difference whatsoever. Tried a few times over a few apps.

Curious, how are you arriving at this hz conclusion?

Here’s a comparison between iPad and iPhone 120Hz: https://www.youtube.com/watch?v=cFvS883E9GY

Thank you. Very helpful. That said, I still don’t know if I’d ever notice this or feel strongly about it unless I was side by side scrolling with an iPad Pro. I stand by my other statements that most people won’t notice this or even care if they did.

True. Most people won’t notice it. And they’ll notice if they go back to 60Hz that their screen is better. But for me, I notice that the 120Hz is not really peaking at 120Hz and mostly capped at around 90Hz. Again, not too much of a big deal but it’s good to know. And it’s unfortunate considering this was iPhone 13 Pro’s main selling point.

People who use high refresh a lot develop an eye for it, refresh rate is directly correlated with the perception of smoothness, you can tell when the animation feels half way between classic age old 60hz iPhone and what a true 120hz should feel, that’s where the number 80-90hz comes from. These findings are confirmed by a ton of other people mentioning 80-90hz since that’s what it feels like to people who can actually tell. Apparently, many people can’t tell the difference and that’s primarily what lets apple get away with it

So this isn’t science. This is your eye. And it’s something 99% of users will never notice or care about. Good to know

Blaming it on “my” eye is just a cope argument. We will never know the true statistic but I would argue it’s not 99%, and the percent would be even lower if people we let to experience what it should actually feel like. There are various videos online with people using external cameras to compare hz on iphone vs android, one of them even has an approximate calculated value of a scroll of 80hz. And most importantly, a ton of people keep repeating the words “it feels like a 80-90hz screen” over and over

Not blaming it on your eye. Just saying this isn’t science. Either way again 99% of people will never notice this. This is the nittiest pick I’ve seen in awhile

You have no idea how much of a serious issue this is, this is a universe away from being nit picky, you just can’t see it, not everyone can. Also, “this isn’t science” is a crappy argument in this case, science doesn’t just magically contradict observation. The only thing that’s not science here is your 99% number. There are people claiming iOS default scroll currently tops off at 80hz max since Xcode has 1, 10, 60, 80, 120hz as defined accessible options for iPhone animations, and apple chose 80 for default scroll api on iPhone. Contrast this to an iPad pro, which only has 10, 60, 120, so apple just gives 120. So far this reasoning is the most likely theory, the only reason why I’m using the word theory is because I’m not an iOS dev and I can’t confirm these findings myself

It not being science is a great argument. Why? Because any semblance of a scientific method here would prove a problem. Instead? I only have your eye to trust on a problem so “serious” that this is the first time I’ve ever heard of it and your own “test” can’t even show an average user (me) a demonstrable difference. Honestly I was all ready to thank you for pointing it out and then be constantly ever so slightly irked that I wasn’t getting premium smoothness. Instead here I am, pointing out your unproven “eye” is severely lacking in concrete repeatable demonstration.

Well, sorry mate, you’re just gonna have to trust my “eye” then. If you actually followed my tests and still can’t see it, then you just can’t see it. From my online observations there are plenty of people who can see it and are disappointed, but there are also plenty of people who can’t see it just Iike you.
