iOS 9 was created to improve performance partly.So yes performance is a VERY big part of each update as its one of the headline feature

"Performance" is subjective once again. It's not a bug or change that can be quantified. All of the tiems in the OP are quantifiable bugs or changes. The lag argument should start another thread as not everyone even sees it.

In fact well over 50% of people in the poll here say 9.2 is faster for them over 9.1, 38-21 (idk what the bottom choice is for frankly). If it wasn't subjective then everyone would be seeing it.

Idk why you're so gung ho about this lag crap and have such a huge objection to starting it's own thread. Doesnt hurt you one bit and lets us actually discuss the beta itself- the point of this thread.

I have invested a lot of $$$ in the App Store.Well over 100$.You cant expect me to just gets hands deep in Android.Apple knows that if they lag out the 6,the consumer will have no choice but to upgrade to 6S

What you said is exactly the point I am trying to make. Potentially Alienating costumers like that on purpose would just be stupid in every area possible.
You guys just need to deal with the fact that iOS is not optimised enough, simply as that, no conspiracy. The reason it might run faster on a 6s is firstly because of horsepower and secondly because iOS always gets optimised for new stuff first. Why can't Apple address older devices faster, well there are a many reasons why that could be.

1) time constraints
2) not enough people
3) other products and services (Apple TV, tv OS, iPad pro with new OS features, 3D Touch, Apple Watch, proactive etc)
4) it's what software has done for years and will do for years. Nobody said this when vista was released and essentially messed up everybody's pc.
5) Tim Cook might be too relaxed and might not have the attention to detail for things like this compared to Steve jobs.
6) OS development is complicated, trust me I know from writing a simple game that has 3000-5000 lines of code. Times that by a billion and it's easy to see why stuff like this happens, doesn't matter if you got hundreds of developers.
7) not enough people
8) not enough people
9) not enough people

You know what's not on this list, Tim Cook saying hey guys lets artificially slow down the software on the devices that literally make up 80-90% of the profits we make. What a great idea that would be at a shareholder meeting.

Coming from android devices, I think lag/stutter is pretty much non existent in iOS 9.
Seeing as my Nexus 5 running Marshmallow offers a smoother experience in terms of OS animations than my Air 2 currently does I have to respectfully disagree.

On the Air 2 there was no lag when using App Switcher.In 9 there is heavy lag when you have 3 or more apps open and you switch between them.Spotlight still stutters

I defiantly do not have heavy lag, it's smooth as silk when scrolling, even with 20+ apps open. If I am picky, and I am picky, than I can see the frame drops when you enter or exit out of the multitasking. Not what I call heavy lag tho by any means. Please show me a video of this so called heavy lag, because I can easily show you how smooth my mutitasking is 99% of the time.

It is quite obvious that all frames drops are generated in moments of intense CPU usage, related for example to the need of loading stuff into RAM (for example the need to reload a keyboard when pulling down the spotlight). But why old models suffer less? I guess that it has something to do with differences in RAM availability between 32 and 64 bit devices - in 32bit ones (4S, 5) there is slightly more RAM available than in 64bit ones (5S, 6, 6+), so they don't need to reload as often.
But in this case 2GB devices (6S, 6S+) should run smooth all the time, so there must be something more... I don't know - maybe devices with bigger screens additionally suffer from the way they scale and downsample images?

ps. as shuttering and frame-dropping dominate all iOS9 topics, it seems that except that, it is really good iteration of iOS.

But they didn't actually specifically state that OS performance is much faster etc, like they said with El Capitan. There are defiantly apps you can tell where metal shines at the moment, Safari being one of them. For me it has never been smoother when scrolling etc. Same for photos and certain other apps. Some app tho still stutter when scrolling like the videos app. Metal is most likely not properly optimised yet, especially compared to El Capitan where you can really tell the difference compared to Yosemite

Ram will not really help with OS smoothness and stutters. App reloading or safari tab reloading defiantly.
You can stuff all the ram you want into an iPhone 4 or 5 or iPad Air 1 etc and it will not make iOS suddenly run super smooth. The air 2, 6s and most likely the iPad pro too, all stutter.

The simple answer to all these threads is that iOS since its redesign with 7 is not optimised enough, certain newer APIs are maybe not designed well enough for older devices, not enough time and different priorties. Add in how complicated an OS is, especially after a major redesign only 2 years ago. I mean how long did it take Microsoft to make Windows run smoothish after the vista redesign? Forever or never until 7 is the answer

Upgraded to 9.2 beta and I see lots of performance gains on the iPhone 6s Plus when it comes to Force Touch. App Switcher cards are fast/slow it's kind of glitchy for me 9.1 was a smoother experience there I think.

Yes, it's totally "everyone". It's exactly those types of absolutes, extremes, and hyperbole that get in the way in many instances.
Read beyond the first sentence to see the real point.

EDIT: Ohai C DM! I just wanted to tell you that Apple fixed that thing where the farthest app icon in the app switcher would pop in while scrolling through it. You know, that bug that you insisted was actually a performance enhancement? Why would Apple remove that "performance enhancement"? LOL!

That's your game plan. Defend Apple first, do nothing later. Deny problems just because you don't have them, don't notice them, or because you're in the business of damage control.

"Oh, my iPhone on iOS 9 just rebooted automatically! This must be one of those new features Apple put in to boost my performance after it comes back on!"
-C DM
It sure says a lot about your argument that instead of actually arguing about the main part of my post, you tried to take it down with a meaningless technicality in the first sentence. I don't have to be 100% literal. You know what I mean when I say "everyone". I don't need to say "all those with dissenting opinions". Find a real argument.

By the way, I'm a huge fan of hyperbole. Sometimes people need to exaggerate their anger because other people would ignore the complaints otherwise.

Did you get your iPhone for free or something? Why do you think the user owes Apple and not the other way around?

Yeah because alienating your costumers by "artificially slowing down devices" makes so much sense.
Some of you guys would be great business man.
That is actually a great business tactic. It may not be slow. But it is slow at just the right times for you to get tired of it and force you to upgrade.

Riiigghhht. Good luck with that
Lemme ask you something.Your customer has invested a lot of money in the ecosystem.So if you did slow down his software at certain places,does he have a choice as to NOT upgrade to your latest product for a smoother experience?

Do you even code bro? Lol
How was windows vista for you when it came out? Microsoft made Windows vista slow on purpose ?
Remember Symbian and how it kept running better on newer devices?
How about the biggest mobile OS in the world in android, notorious for running terrible on older devices?

So apples master plan is to make every costumer unhappy with the software on their devices by purposefully slowing them down each year? Than these customers just happily buy a new product each year, no questions asked? They would risk their main stream of income for this? Yeah let's not make a kickass phone or ecosystem that makes costumer come back for more anyway, lets artificially slow them down, so they are forced to buy more.

My whole assumption of why Apple is the biggest and most profitable company in the world has changed. Brilliant, Evil Tim Cook

So the point of that first sentence was basically nothing then? Why include it then, and as a leading sentence too? No need to answer though, they are rhetorical questions given that the answers are fairly clear.

As for the edit, where exactly did I insist on something? Perhaps you just like to twist things into extremes that you like to fit your narrative instead of actually taking them as they are? Seems like you basically admitted to doing all of that with all that hyperbole talk.

Not sure there's anything more to say there given that you basically just said that anything you say can easily be (and certainly has been) exaggerated and twisted. That pretty much ends any discussions right there since they would be pointless, as they pretty much have been.

What does "defiantly" mean? Isn't it "definitely"?

Can't be assed to read the past 16 pages, but my personal experience on my iPhone 6s Plus (restored and installed "as new") is that everything is much, much smoother now. Animations seem to be quicker, and don't drop frames like before. On previous versions, for example, when I'd 3D Touch an icon on my home screen, the animation for the pop-up menu would lose frames and it looked terrible. Now, it's very smooth. And improvement like this is consistent across the device, for me.

Battery life seems better too.

No, its not that drastic difference in RAM use b/w 32 & 64 bit...also don't forget that the 5s & 6 (& 6+) use LPDDR3 RAM vs LPDDR2/DDR2; the RAM is faster (1600 mbps vs 1066 mbps) and offers much higher bandwidth among other improvements. The RAM in the 5s and 6 is actually better, not worse.

Besides, the A7 and A8 are much, much more powerful chips than the A5 and A6, so CPU workload moments as a limiting factor should also be demonstrable with the 32 bit devices as well, rather than only with the 64 bit devices.

With the 6+, there is the downscaling issue which was an issue even on the "buttery smooth" iOS 8, the hardware itself is capable but has to push more pixel plus downscaling every single image

I think it is likely more so difficulties with Metal coding or some kind of GPU issue with the 64-bit devices that Apple hasn't sorted out yet or hasn't got around to optimizing yet. In theory, the 64 bit devices should feel smoother than ever but in practice there is head scratching lag that shouldn't exist based on Apple's comments on improved performance specifically using Metal.

Consider that the A7 and A8 are still some of the most powerful mobile chips on the market; if weaker android hardware (Nexus 5) can run the latest Android software version smooth (as apparent anecdotally), that tells you its more a software issue than it is a hardware issue.

When people are experiencing animation lag at very specific moments on the 6s (which is by far the most powerful smartphone on the market) then that adds credence to the narrative that its likely a software issue

The 5s and 6 are still very usable on iOS 9 and mostly smooth, in my experience. I think the 4s ran smoother on ios 9 than it did ios 8 personally, even if apps launched a little slower, there were less skipped frames and animation lag.

No, I'm not twisting anything. Here's your response to me after I pointed out an app switcher bug (which WAS a bug because Apple fixed it):
Or perhaps that's an enhancement of sorts so that they need to render less initially and only load it when someone starts scrolling when that icon would actually be needed?
Your instinct is to damage control. Your first thought was to make an excuse for Apple and suggest it may have been a feature.

The point of the first sentence was to capture the attention of anyone that disagreed with me. I can tell it was certainly effective because that's the only part you can acknowledge. God damn. You still didn't make any statement having anything to do with most of my older post. How about going back and reading all about acceptable frame rates, which was the point of my post in the first place?

I love how you make this an opinionated argument. My narrative? Really? I can measure frame rates objectively. It's an INDISPUTABLE FACT that the iPhone 6s (especially Plus) on iOS 9 has visible frame rate drops in certain situations, going sub-30 FPS. All units. This was not the case for the iPhone 5 on iOS 6. It's not my opinion that the iPhone 6s Plus gets 30 FPS on its 3D Touch menus. However, it is my opinion that performance on the more expensive iPhones should be equal or better than the older or less expensive ones, but you have to be a professional Devil's advocate to disagree with that. Which is what you're telling me. Somehow you think if I pay $100 more for the iPhone 6s Plus, it having substantially lower performance (MEASURED, DOCUMENTED, AND PROVEN) is somehow okay.

If you're still arguing that the performance issues don't even exist, you're wrong. That's because it's not an opinion. Don't give me your theory about certain pieces of hardware being a variable and blah blah blah... NO, THERE ARE PERFORMANCE ISSUES ON THE iPHONE 6S AND 6S PLUS AND IT HAS BEEN PROVEN BY THEIR FRAME RATES COMPARED TO OTHER iPHONES ON DIFFERENT SOFTWARE VERSIONS.

Have you noticed poor battery life? I've been losing way more than I think I should be on my 6s and may switch back to 9.1.

Yes I have. The phone went from 100% to 90% in a matter of minutes, and I got the 6s plus version.
It's now redownloading all 2500 tracks from Apple Music to my device -.-

And geez - it's hot.
