Too many secrets

I'd love to see someone do a blind test/study to see how many people can truly tell the difference between ProMotion and non-ProMotion displays (120Hz vs. 80Hz vs. 60Hz)...and how many are just placebo effects.

Also, developers of third-party apps need to enable ProMotion support in order for their apps to refresh faster. It's basically up to them to decide whether battery life or 120Hz is more important. Maybe this 80Hz thing will be a new option for a middle ground/compromise? I wonder how many of our favorite apps don't even support ProMotion. Is there a list somewhere?

I can 100% see a huge difference in having promotion on vs turned off via low power mode on my phone.

It’s night and day.

In the past, I can’t tell when I go between my iPad Pro vs iPhone XR. I still can’t tell between the same iPad Pro vs my current iPhone 15 Plus. If I look very very closely, I can kinda see the scrolling is less smooth on the phones..but once I let that go and use normally, I don’t notice the difference. I have tried turning off ProMotion and can barely tell the difference during normal use (but I do leave ProMotion on).

Isn’t that the whole point that it doesn’t hit 120 unless it’s necessary? Scrolling still looks completely fine to me.

It’s one of those things you don’t notice unless you’ve already used it previously. Once you use it you’ll be able to tell immediately when you go back.

Night and day difference when I go from my iPad Pro to my iPhone 15 as far as smoothness when scrolling

This is the mind trick.

I don't think low-power mode on pro phones equals non-pro phones running on full power.

Reasons:

1. ProMotion is not turned off but capped at 60 fps, lowering your average fps observed below 60.

2. Clocked down CPU and GPU cause load time noticeablely longer on demanding tasks.

iPhones have had adaptable refresh rate in their promotion since 13 Pro.
This is not something secret, but facts written in technical specifications.

If you are just slowly scrolling webpages for example, there is no need for 120hz.

There is a video of the user scrolling very fast and the refresh rate utility showing it locked at 80 Hz

So, is it the same on previous phones? And no one actually has noticed it before (not measured - but actually noticed)?
Then it's pretty much a nonissue.

Wonder how well this works to preserve battery. Seems like it's 120hz when accelerating and decelerating, 80hz when at speed.

If it looks good, who cares about the specifics? There's a reason they call it ProMotion, not 120Hz.
