Haha you didn't even get @Radon87000 point. 5c doesn't use Metal to accelerate UI animations and hence it is the only device which is flawless and does not stutter. But 5S and 6 which are more powerful than iPhone 5c stutter. That is not fair isn't it?

I have a 6S and it counters Metal's inefficiency with brute hardware power. But it is still not as smooth as 5c in control center pull up menu.
Sorry totally disagree with you. I have a 5s, a plain 6 and a 6s (among others) and they all work perfectly under iOS 9. So what's fair in your estimation?

Has it ever occurred to you that if the majority of people aren't experiencing the lag and stutter you describe then maybe it's your particular phone. The amount of effort people go to, to make YouTube videos bashing the screen of their phone, building "evidence", starting class action lawsuits and becoming plaintiffs is amazing - all the while, time would be better spent restoring the iOS software and the backup. I'd be surprised if the problem persisted after that but if it did you could start fresh and install one app at a time until you find out which one is causing the problem (or switching off background app refresh altogether) or taking it to an Apple Store to check the hardware.

I can say first hand after setting up an iPhone 5C for a friend this Christmas that it runs so smooth on iOS 9 I was actually surprised (after reading the amount of nonsense on these forums).
Backup and restore does not fix the problem. If that were the case, we wouldn't have been discussing the lackluster performance of iOS 9 for months now. It's also been established numerous times that the iPhone 5 (and 5c) actually runs iOS 9 smoother (not faster) than the 5s and 6.

Furthermore, we've also come to learn by now that iOS 9 is the problem, not a particular phone. Different experiences can be attributed to different standards people have. This has all been discussed for months now.

He states that the 5 runs smoother than the 5s and the 6. You apparently don't have a 5, so how can you disagree with him? Please read carefully. In a direct comparison (basic clean iOS 9.2 install), the iPhone 5 is smoother than the iPhone 6.

Also, fair would be the same level of responsiveness and smoothness as iOS 8.4.1.

Hahahaha. Read my post again and you will know that 5c and 5s are completely different devices with different CPU architectures. 5c does not support Metal API while 5s does.

Summary:
5c = 5
5c ≠ 5s
5 ≠ 5s

5 and 5c do not stutter in iOS 9's control center or anywhere for that matter. However they stutter like crazy where ever tables API is used like in WhatsApp recent chats list.

5s, 6,6+ all stutter in control center when it is swiped up beyond 50 % of the screen.

Edit: Saw people have liked your post which is totally ignorant. :D
Brought a smile on my face.

About the iphone 5 guys. That's the only lag i noticed and I just want to be sure that you others are facing the same problem: having multiple windows open on Safari, once you scroll up and down, doesn't it feel sluggish? like it s not fluid at all. Did anybody experience the same "lag"?

You were ignorant of the fact that he said ios9 works fine for him on his devices despite your opinion on Metal's performance. Then he listed a bunch of devices that use Metal to prove the point that it works fine for him on devices that use Metal which is his opinion and he's entitled to it as you are entitled to yours.

Yup. Where ever tables API is used, the smooth scrolling stops working on 5 and 5c.

Good for him. Thumbs up!

Performance is not really the same as occasional animation stutters in a few places aren't really the same thing.
It's not occasional. Pretty much all scrolling is affected, even swiping between home screens is not smooth.

Meanwhile the 75 million other iPhone users do not experience any "lag" or "stutter", including iPhone 6 users like me who are "doomed" with "metal".

Might be worth reading about it before making such bold claims:

"The apps in iOS 9 now take advantage of Metal, making more efficient use of the CPU and GPU to deliver faster scrolling, smoother animation, and better overall performance. Email, messages, web pages, and PDFs render faster. And multitasking features on iPad feel fluid and natural."

Point stands, if you are experiencing individual issues with your phone, then you need to treat it as such. Perhaps even a hardware fault exists - ofwhich apple are really good at resolving, even out of warranty. So quit talking rubbish and get yourself to an Apple Store.

interesting observation and this, if true, would totally debunk the "planned obsolescence" theory some here have yes? I mean if 3 or 4 generation back devices actually work better than the newer ones.

It may not debunk this PO theory as even 5c and 5 are brought to their knees just by scrolling in Apps like WhatsApp.

I have come to conclusion that Apple absolutely does not care for device 1 year old. They stop optimizing it with next version of iOS. So whether ignoring your older products within 1 year is PO or not is where all debates on MacRumors originate.

When people raised the hell with stutters in iOS 8 on iPad Air 1 and lower products, Apple conveniently ignored them with the exception of Weather app. My friend has kept his iPhone 5S on iOS 7.1.2 and good god it is a delight to use. It is smoother than butter, security holes aside.

Apple better give 60fps smooth UI performance everywhere in iOS 10 (iOS 9 is a lost cause at this point). They must make sure Metal API works at almost same level as OpenGL or drop Metal for UI purposes.

That isn't what most people experience. Even many of the ones that are noticing the stuttering and complaining about it have pointed out about it being just in some places. If anything this simply goes back to what I've been saying from the beginning, that while some of the smaller occasional things might be there for everyone, something beyond those isn't something that's there for everyone.

I agree, this issue is completely overblown.

While there are frame drops in cases like activating control center while using Siri, dragging down Cellular Data list, etc, they are really obscure use cases. It would be nice it could be dealt with, of course, but I certainly don't expect it to be top on the to-do list.

Are you wasting more time ignoring that stutter you just happened to chance upon, or will you waste more time dedicating all your forum posts in the last two months on this issue and loading some "fps monitor" to check every corner of the firmware under every device for every build of iOS released?

When I'm here on MacRumors, I like to help people with functionality issues in OS X and talk about things like third-party accessories, new features, upcoming hardware and so on.
Otherwise, I like spending my time outside and getting some coffee.

Seems pretty quite here so is that an indication not a lot of issues with 9.2.1? Only issues I see is same as all of iOS 9 in that the DND scheduled time is overlapped (from/to and the actual times). Battery seems better than beta 1, not that I was having issues with b1 but does seem great for me. Others stated the MDM issue was addressed with b1 and I can only assume still working in b2. Is this indicative that perhaps 9.2.1 is about baked and ready for release soon?

Guys - you hijack every beta thread. Its a mess. Open a stutter thread and leave us alone here. For Christ sake
The thing to top it off is that there are already probably about a dozen such threads that exist too, and the discussion just goes around in the same circles.

Every time there's any thread about any update, or about somebody enjoying their new device, somebody will show up to preach the word of the stutter. It happens, yes, but I agree that the topic doesn't need to invade every other topic.

Those examples are the extremes. People are complaining about control center stutter everywhere, stutter when pulling down spotlight and the occasional but more frequent stutter compared to iOS 8.4.1 when opening apps and folders. These are actions you perform many times a day. 8.4.1 had stutters as well, but on less used places like the weather app when collapsing the city list which is now fixed with iOS 9.

For me the stutters are real on every single device I've tested(my 6, friends 6's, apple store's 6/6s, iPad air 1 and 2, iPad mini 2). I've just stopped caring as much as there is no point. It has gotten better overall with 9.2.1 and app switcher stutter is almost gone which bothered me the most. iOS 9 feels like a jailbroken device running a heavy theme. Still won't buy anything else though. :)

To be clear I have the following in the family: iPhone 5, 5s, 2 iPhone 6, 6s and a 6s+. All are running iOS 9.2 with the exception that my personal 6s+ is running iOS 9.2.1 Beta 2. Completely counter to your observations, all the iPhones run iOS 9.2 smoothly and without any issues. Of course the feature set available is dependent on actual iPhone but at the very least they all benefit from current security fixes, iOS 9 updates, etc. For me iOS 8.4.1 is a non starter even if it were blazing fast as you claim.

My supposed 120mbpsfrom XFinity is non-existant. No idea what it is. But its been night and day across all devices. Im in UT. WiFi on 5GHZ is just an absolute horrible experience on all of my iOS devices. The Macbook is fine and never drops. Maybe I just need someone to help me configure my home network properly. Plus a son who plays LoL and PS4 and Xbox for hours on end might not help either lol.

I noticed this too on my end. I have TWC's 100mbps services coupled with an all-in-one router with the wifi turned off coupled with an Airport Extreme (older flat model). on 5ghz our service flies. 2.4ghz...not so much. I've done everything with changing the channels and putting it in an optimal position in the middle of the house. Again, the 5ghz network is incredible and the 2.4ghz is just not. I understand the reasons why, but my iOS devices (mainly just my 6) would drop off the 5ghz network even with full bars. It was uncanny. Hopefully this new update addresses this?

Except for the fact that you have pointed it out, it seems, thousands of times. We get it. We're not Apple. File a bug report.
