iOS 15.4 Will Allow Third-Party Apps to Take Full Advantage of iPhone 13 Pro 120Hz ProMotion Displays

Looks like WFH impacted engineers greatly. I don't recall Apple being like this before the pandemic.

They've been doing long before COVID, at least with iOS features that were announced at WWDC, only to be implemented later, or even when a new iPhone was announced, some features would only appear later in mid-cycle.

Seems more of a deliberate move, if there was no bug or it got fixed ASAP, the phone’s battery life would most likely drain faster and that would go against Apple’s marketing claims of the best battery life ever on an iPhone.

Let the drain games begin!
 
this was identified when the new iphones dropped. 4 months later and we get a beta for the fix? so it'll be 5 months to see it through?

cool. just keep that in mind next time they show off a major feature, that if there's anything wrong with it, flagship features from presentations arent going to get fixed quickly.
 
The new Apple. Buy device (in this case iPhone) in September with features that either don't work or half work. Wait until .4 software update in March for phone to work as sold. Buy new phone in September...
 
See, it's this sort of stuff that just makes me roll my eyes. The iPhone became so huge because it had features that average people not only understood, but wanted. Things like digital music, a store to buy apps, a camera, GPS, a voice assistant etc. But a lot of the selling points these days are so techie, that the average person just isn't going to care. Yes, they buy their new phone every year, but that's just because they're trained to believe new=better. It certainly isn't because of Pro-motion, or how many hertz their screen operates in.
 
Immediately reminds me of genshit impact that has a setting to run the game at 120FPS, despite A15 clearly incapable of running the game at that speed with maxed out quality setting.

This third party support is going to be sketchy as usual. I’m looking forward to comments talking about Apple tightening third party support control.

Tried to pull both and got none. Typical genshit pull. I don’t have $50000 for pull.

The 120FPS option lags game extra hard on M1 I’m surprised it is there as an option. Negative optimisation at its maximum.

The real embarrassment is that this wasn’t a thing at launch. Not sure if it’s because software engineers work from home, but it shouldn’t take 4 months for this to happen (still in beta so it’s going to be longer than 4 months)

Just got my 14” MBP M1 Max in on Tuesday. No 120Hz scrolling in Safari until Wednesday. I thought my machine was broken since ProMotion was enabled in System Preferences. It’s amazing (pathetic) how they only added 120Hz scrolling in their very own web browser 3 months later. It seems like the software engineers don’t find out about new hardware features until the general public does. For a company that prides itself on tight integration since they make hardware, software and services, it’s kind of an embarrassment.

Such a drama about something that’s a little more than a gimmick for marketing reasons. iOS always has been smooth also on 60 Hz display. Apple was forced to implement 120 Hz on iPhone mainly because the competitors’ spec list was longer.

I dunno this guy looks sus

EDIT: In all seriousness to clarify because this all can be a bit confusing, basically with iOS 15.0 *system* animations (as well as those present in apps) worked at 120 Hz right out of the box. So off the top of my head we're talking scrolling, system views like context menus, as well as view controller transitions (so transitioning from one screen to another within an app) have *already* been 120 FPS.

What *didn't* work in third party apps was custom animations. So like the Tinder example someone else mentioned, if as a developer I was to put a view on the screen, and wanted it to move somewhere else in response to a user tap or gesture, the result would only have animated at 60 FPS. This was contrary to say, the iPad Pro's ProMotion implementation that worked at 120 FPS for those custom animations.

This contrast between some animations (or even most!) flying around at a gorgeous 120 FPS but some still being at 60 I think was jarring to some users and what prompted the discussions.

With iOS 15.4 I can only guess that they figured out that their fears about the 120 FPS animations taking too much battery weren't as bad as they thought, or they made some optimizations (like I mentioned in the tweet, where it automatically downscales the frame rate where it doesn't need to be high on iPhone, like in slow animations, as opposed to the iPad where it's *always* 120 FPS). Or a combination of both of those!

But either way it sounds great and it's automatic going forward, so I don't think you'll have to worry about your favorite apps having to "add support" for it, I would assume compiling with the newest version of Xcode will just flip the switch (and I'm not even sure that's needed, it might just be flipped on at a global, iOS level).

(Hopefully that answers Kylo's question if not I can clarify more if needed!)

this applies to horizontal animations as well right? i know some devs mentioned those could not go above 60hz

btw apollo fan checking in :)

this should be a day one feature... (not rushed to the market with 120hz, while under the hood still crippled)
now it looks like .. apple is doing something good to allow this..
silly.

Totally agree. But nevertheless the average user might never really notice the difference and not everyone is buying the new iPhone day-1.

No wonder some people would post that they swear they can’t tell the difference between 60hz vs 120hz. There’s a good chance they were unknowingly comparing third party apps. :oops:

It’s still strange. If third parties using the standard animations offered by iOS it works with up to 120 hz. The bug only occurs with 3rd party animations.

I bought an iPhone 13 Pro Max that was advertised as having a 120 Hz ProMotion display and then I don't get 120 Hz on all my apps until months later. Why isn't this a class action against Apple?

I don’t understand what they mean with “full support of ProMotion” exactly. Earlier reports said devs could enable it already with a plist entry. What does this News mean exactly?

Promotion definitely already works in most third party apps. People mentioned Instragram but I can plainly see that it’s already 120hz. Just to make sure I wasn’t crazy I also checked again with limit frame rate to 60hz turned on in accessibility and the difference was immediately clear: Instagram looks MUCH smoother when “limit frame rate” is turned OFF. So it must’ve already been using 120hz in some form.

The same is true for most other apps I’ve tried.

Anybody know what this News means Exactly on a technical level? As far as I understand it, it only means that promotion will work automatically without devs enabling it?
