    Like some people mentioned here, the irony is that 32-bit devices are actually performing better on iOS 9 than 64-bit devices.

    I was trying out the 6s at the Apple Store yesterday and I saw lag pretty much everywhere. Control Center, App Switcher, Spotlight Search, etc. It's not the 6s itself, because it's ridiculously fast. It has to do with issues with Metal on iOS 9.

    It's the only hypothesis that makes sense, because iOS 9 runs really well on the iPhone 5/5c (the 4s is already really slow, so that's the only exception) and the iPads below the iPad Air with the A7 that supports Metal run it well as well.

    Apple Music definitely doesn't use Metal yet. It's very choppy on iPad Air 2.

    Not sure that has to do with Metal.

    I don't have Apple Music, but I use it extensively at the Apple Stores.

    The app is horrendously bad. I don't know why, maybe it has to do with the way it caches things, because the more you use it, the laggier and choppier it gets.

    It gets to a point where it is unusable (I tried it out on a 6s and 5s, same issues exist). I thought iOS 8.4 went through like 5 betas to perfect the Music app for Apple Music?

    My friend just got a hand-me-down 4s (Verizon) and it had 7.1.2 on it. He couldn't get his sim card to work on it, so the Verizon guy told him he needed the latest OS (which is kinda strange). I told him not to update and that it would kill his phone, but he did anyway. Now he hates it. It runs like a slow piece of crap, but his sim card actually works in it now.

    Oh well, that's what happens when you're forced to update your phone.

    Verizon 4s didn't need a SIM card to work on Verizon and only supported SIM cards for international GSM providers as I recall.

    Hmm, he put his 4g sim in, and he got service for a few minutes, then it stopped working completely, but when he took his sim out, it worked for texting and calling but data wouldn't work. So he talked to the Verizon guy and he told him to update his phone. Now he has data and phone/text. Figure that one out. Hah.

    I'm not familiar with Verizon as I've only ever had AT&T.

    Because a lot of apps won't work with iOS 6 anymore.

    I'm exceptionally curious about the iPad 4 vs iPad Air/mini 2/3. I've never in my life used an iPad 4, so I just want to compare it with the 1st gen of 64-bit iPads, because those things have been awful from the get go.

    I know metal is negatively affecting my iPhone 6, because I've used a 5, 6, and 6S all on iOS 9.1, and control center for example comes out on top with the iPhone 5. I just want to know how bad metal is negatively affecting my iPad mini 2, since that thing right now is a piece of garbage in terms of UI frame rates. The entire app switcher experience is sub 20FPS, where it usually is almost perfect on iPad mini 1 (although that lacks the blurring effects and Retina display)

    Hope you people also posted feedback to Apple on http://apple.com/feedback about the stuttering issues and what could be the possible cause (Metal). More of us, better it is.

    There are also people on Apple community forums who are walking into App Stores and exchanging devices now because of this. Naturally new devices don't help. So I guess it's slowly time for Apple to own this **** publicly and starts amending for it.

    If you are lucky the new device could come with 8.4.1 which fixes almost all the issues

    8.4.1 would be as far as I'd take a 4S at the moment. I put my Mum's 4S on 8.4.1 just before 9.0 came out and there was a speed hit going from 7 to 8, and there is definitely another speed hit going to 9.

    Since iOS 9 didn't add anything to the 4S to make it slower, I don't quite know why it performs worse than 8, besides it perhaps not being optimised well yet?

    The device in this particular case was a 6S+.

    Oh I know... iOS 9 on the Mini 2 is a freaking disaster.

    I've reported it a lot. I have put in like 6 reports alone about how bad the app switcher is on my iPad mini 2, was back in the 9.0 betas. They claimed it was fixed.

    They wanted me to send some logs back to them, and I tried doing it but every time I tried to send in the reply it would get an error and it wouldn't work. So that's that. Everything else was fine, even replying to other things were fine.

    I reported how quick reply is insanely slow back then too and they claimed it was fixed but it wasn't. Still lags today.
    Yeah I can't stand it. I already thought it was bad on iOS 8 with all the app-to-homescreen lag, and the multitasking lag when a keyboard is open, control center having issues on lock screen, over keyboards, over open folders, Siri lagging, etc etc etc. but yeah, nothing even compares now with iOS 8 vs iOS 9. It is SOOO bad.

    iOS 9 actually runs fine on the iPad Mini first generation. Apple logic.

    Because it is a ABSOLUTE NECESSITY that iPad Pro is faster and smoother than any iPad out there and if ṭhat means crippling the older iPads as powerful as the Air 2 intentionally than Apple doesn't have a problem with that seeing as iPad sales are coming down

    I was so excited to hear that iOS 9 was focusing on improving that stuff, but my heart sank when I realised it was worse than before...

    Yeah i did as well on all the devices I ran on the beta.. and no real improvements.

    I know right? I've used the mini 1 and it is much smoother than the mini 2 in the app switcher and spotlight! Spotlight pull down for mini 1 is 60FPS all the way around, even keyboard popping up. It's like 20-30 FPS all the way around on my iPad mini 2. App switcher is also great on mini 1. Coming out of the switcher suffers a little, but going into it is fine.

    Here's how it goes with mini 2 vs mini 1 app switcher performance in terms of animation smoothness

    Default settings on both:
    Scrolling: mini 1 > mini 2
    Enter/exit animation: mini 1 > mini 2
    Closing apps: mini 1 > mini 2

    Mini 1 wins hands down.

    Increase contrast enabled on mini 2, still default on mini 1:
    Scrolling: mini 1 < mini 2
    Enter/exit animation: mini 1 = mini 2
    Closing apps: mini 1 = mini 2

    Now they're the same, mini 2 is only better with scrolling.

    We should not have to disable things on NEWER devices so they can perform BETTER than OLDER ones. This all is just because of that stupid depth of field blurring effect. Also, on newer devices with blurring in the switcher, whenever you go into or out of the app switcher, the app previews are blurred in real time when you are entering/exiting, heavily contributing to the in/out animation lag. Older devices only dim them out, and they have no blurring in the distance while scrolling. That's why they're smoother. It's pathetic that Apple feels the need to add these pointless effects and cause such performance issues. I LOVE eye candy but I much prefer smoother animations. Increase contrast is way too much of a compromise in my opinion, however. Can't do that.

    iPod 5 (same as iPhone 4S internally) is also smoother than iPhone 5 with the app switcher, besides scrolling. More sluggish though with registering the tap and scrolling, but going in and out of there is smoother.
