5s runs smooth and fast on iOS 9 for me... - the 6 is similar in power, so it shouldn't be too far off in performance and if it runs fine on 5s, it should be fine on the 6 too I would imagine ....

that said I don't have a 6 anymore and never used iOS 9 on it so I can't comment too much, other than how the 5s runs for me.

Heck the 4s runs fine on iOS 9 for the most part! Actually has smoother animations and less laggy frames than it did on iOS 8!

For the most part when an animation stutters and drops frames, the overall length of time it takes is still the same. You don't lose time, it's just a bit ugly to look at. So, to say it's slow and unusable is quite an over exaggeration.

Take it to the feedback app and tell Apple directly. Making 20 threads by the same 20 people doesn't help Apple or make them any more aware.

My iPhone 6 has the stutter occasionally when launching or leaving an app, going into or out of the app switcher, pulling down the spotlight (mostly only stutters the first time pulled down after a while.) It's ugly to see, but doesn't bother me enough to get me all angry and hateful towards it. I still report it though, because there is always room for improvements.

I'm sure some stuff exists and maybe it's worse on some devices than others; but it's not a general case the for everybody iOS 9 is worse.
i was exaggerating on purpose , because I'm sure there could be someone trying to show me a lag i can't see.
I actually use it for hours today, with my iPhone 6 at its side, and i couldn't see any noticeable difference...

To be fair to the OP, I used an iPhone 6+ for two weeks before I got my 6S and I saw many of the same issues on iOS 9 Beta (that were not fixed with the GM). The most annoying was the huge lag when opening the camera. 4 seconds sounds about right.

Pseudo scientific test - Camera :cool:

iPhone 6 plus 64GB with only stock apps loaded. Nothing from the store. Camera set to default and removed each time from the Task Manager.
From icon press to camera open and ready:
2.7, 2.8, 2.9, 2.7, 2.9 :eek:
Call it 3 seconds.

iPhone 6S Plus 64GB - same conditions
1.2, 1.2, 1.1, 1.3, 1.2
Call it a longish second (scientific term: longish):rolleyes:

Note 5 64GB - clean task list with widgets running (clock, weather, stock ticker, calendar)
0.8, 0.9, 0.8, 0.8, 0.8
Call it a short second (another scientific term):rolleyes:

6+ camera takes way to long ...... :(

I have a 6 Plus. Does it stutter? Does it lag? Is it crap?

I have no clue. Sorry, I don't waste my time looking for dropped frames and things that work perfectly fine, but don't display perfectly. I unlock my phone and load whatever app I was interested in when I unlocked my phone. Then I happily use my app (happily, because iOS 9 does just as well at running the apps I'M interested in as previous iOS releases). If I get tired of using that app, I load the next app or simply turn my phone off. I don't play with the task switcher to see if I can find flaws. I don't open folders for no reason other than to see how well they open. I don't unlock my phone over and over and over to see if unlocking it is better or worse than it used to be. I don't investigate each and every animation found in the system in an attempt to find something not working 100% correctly.

For me, iOS is just the base that all the fun stuff runs on. It's not the end goal. I don't sit around "playing with" the operating system. Thus, as long as it works, I can easily deal with some minor display issues that don't have any actual effect on me or the apps I'm looking to use. As long as my app runs properly, I'm perfectly happy.

For those curious about my "power user" status, I've had an iPhone since the 3G and have worked professionally as a computer programmer for the past 25 years. Not that it should make a difference, but there are those who seemed to zero in on such things, so there you are.

We don't "play" with things so we notice them. We notice a reduction in the smoothness in which the UI operates. When these dropped frames are instantly noticeable, it detracts from the user experience. iOS built its reputation on a fluid and smooth UI, that is undeniable. Don't write off people's experiences just because you don't care about the UI. Thankfully 9.1 beta 4 fixes most of the stutter.

So if some folks are not having the issue, is it isolated cases that maybe specific to their phones? Doesn't sound like a pandemic to me so maybe blaming iOS 9 as the culprit is inaccurate? What troubleshooting have you done?

My 6 running 9.1 b4 opens the camera within a second but even on 9.0.2 it didn't take 3 or 4 seconds.

yea my air 2 opens camera in about 1 second, using 9.1 b4, my biggest gripe with ios 9 and above is the screen responsiveness. if i close safari and immediately tap the camera icon, it will not register the tap. this is with reduce motion on. i guess i need to train my brain to slow down before selecting my next app.

Everything. As I said, 9.1 b4 fixes the stutter in the places I noticed it, all on freshly restored "blank" iPhones. Can't be arsed going into more detail. Some people notice UI stutter, some don't. It's that simple.

How can people not see stutter when pulling up the control center in the lock screen on their iPhone 6S? I guess it comes down to the debate about 30 fps vs 60 fps. some people just cant see the difference.

If it is there on all phones, maybe most folks don't care because we are talking milliseconds. I just tried it on my iPhone 6 and I didn't notice anything crazy. I guess most people focus on the end result which maybe why folks aren't noticing?

I wouldn't mind if it was like that on an older phone like the iphone 5 or something with weaker hardware. This is the iPhone 6S that is having choppy animations and my iPhone 5 which is running it smooth.

That is a HUGE issue.

My 6 running 9.1 b4 opens the camera within a second but even on 9.0.2 it didn't take 3 or 4 seconds.

When I ran my "test" it was a single object test. I gots what I gots - just under three seconds repeatable.
I do not know if or how much the carrier or lack of affects the speed nor if there are any background Apple processes that do.

Sorry, I disagree. It only detracts from the OS UI experience. I suspect most people only care about the experience their app provides, not the launching of the app itself. I don't deny that there ARE people bothered by how the UI performs. This very thread is proof of that. I'm also not attempting to claim that there are no problems. I've seen problems myself on my own phone. I'm also not opposed to bugs getting fixed. I'm just saying I don't really care. As long as my apps run, the rest doesn't matter to me. Or to be more accurate, it matters very, very, very little.

I suspect many people feel the same way I do. I also suspect that some of those who are saying "everything is great" are perhaps looking at things from a different perspective from those who say it sucks.

Don't write off people's experiences just because you don't care about the UI.

I wrote off NO ONE'S experiences. I very intentionally kept it very much about me and my experiences and my own personal preferences. With that said, I will say I see a small percentage of people (not everyone!) making a HUGE deal out of something relatively minor in the grand scheme of things. It's not like apps aren't loading or they're crashing or people are bypassing security and breaking into our phones or calls are being dropped or etc. For the most part, things are running fine. There's just some bells and whistles that aren't working 100%. And the vast majority of those issues are occurring well before the person ends up inside whatever app they were trying to use. To some people, that's important. But in my opinion, I would guess that group to be a fairly small percentage of the overall users.

the difference is amazing between a "finished" product and a "beta", would be interesting to see how 8.5 would have been except the time ran out as every year a new ios must be released

9.0 is basically 8.5.

What troubleshooting have you done so far?

Clean install? Check to see if things are working as advertised before doing any restores or app installs?

Did you talk to Apple and can you reproduce the issue consistently to show them?

Can you wait until 9.1 next month?

Have you tried the 9.1 Beta?

I already downloaded the 2Gig firmware file and setup up as a new phone but nothing changes.The only thingI Appreciate is at battery life has increased

Already tried Apple support.They said they forwarded the issue to the team and see if a restore fixes the problem

I haven't tried 9.1.I can't try beta software on my daily driver

I guess all those people who have complaints in various Microsoft and tech forums related to sub-par experience they have with Windows 10 must be making it up then?
I am talking about animations,The OS itself may be slow but the animations don't stutter.

So basically you are trying to not notice the lag because it's hard to "unnotice" it once you see it.
Going by your logic even Android doesn't lag because you try not to play with the OS

If it is there on all phones, maybe most folks don't care because we are talking milliseconds. I just tried it on my iPhone 6 and I didn't notice anything crazy. I guess most people focus on the end result which maybe why folks aren't noticing?

The animation is running at low frames.Turn on reduce transparency and then use the control centre.Turn it off and you will see how stuttery it is.Try using it in the app switcher and lock screen.Those are the worst culprits

So occasional trivial animation inconsistency is then worse than an OS itself not performing well? That's certainly a standard to live up to.

So as long as the apps perform fine you don't care that the stutter is there in the OS UI when opening, closing, and navigating?

Fair dues, but I think that's madness. I can accept degradation when updating an old device (more than previous gen) but not on the just replaced flagship phone that ran the same OS graphical effects and elements smoothly. iOS is/was renowned for its fluidity and smoothness, the day we start accepting that it's ok for the OS to be laggy because the apps work ok, is the day we begin accepting sub standard products from Apple.

As I've said about forty times now, 9.1 fixes the stutter in the UI where it's noticeable in 9.0.2, so this is no longer an issue for me.
