While they're busy counting money, they managed to ship an iOS who stutters on their flagship phone : https://www.youtube.com/watch?v=cGCA_v4WUaI https://www.youtube.com/watch?v=cGCA_v4WUaI The performance downgrade is even worse on last years 6, 6+ and 5S, they stutter and drop frames while scrolling.

I really don't understand why you got downvoted. I am extremely worried by the latest iOS release that managed to make an iphone 6s laggier on ios 9.1 than an iphone 5 on ios 8 for an app i'm currently developping. Provided that ios 9 brings absolutely nothing fundamentaly new, and how buggy ios 9.0 was, that makes me hope really strongly that they had the interns work on that release while the good developpers were working on revamping the whole os for ios10. We all know that blackberry was still making great sales until the very last moments of its expected collapse, simply because good business managers always find a way to grab some profits in the short term eventhough things look bad in the long term.

  I'm not surprised, it's hard to break Apple bias (and I own an iPhone), also some people don't see the difference between 60 fps and less. Regarding the performance degradation, I assume it has to do with Metal. Apple said iOS9 will feature Metal as a replacement for OpenGL throughout the system for better performance. Well we didn't see any of that. The stutters have been there since Beta 1 in June.

    Oh ok, the change to metal explains it all then. Thanks.

  iOS 9.1 is causing major performance issues on the iPhone 6s? I assume the recommendation is to stick with 9.0.2 at this point then?
  - tdkl 11y ago
    You have no choice with 6S, since it shipped with iOS9. 9.0.2 stutters too.
    - jlgaddis 11y ago
      Yes, when I bought it (at the Apple Store), it came with iOS9. I have updated it to 9.0.2 but have yet to update it to 9.1. I haven't noticed any problems, though (except for one issue with the Facebook app going crazy -- so that the phone was hot to the touch when I picked it up -- but that only happened once).

    9.1 is actually better than 9.0, so you should upgrade. I told my client who told me about performance issues to upgrade to 9.1 to see if it's better, and it was, but just a little bit. We were then stunned to discover that his old iphone 5 ( not even 5s) performed better on ios 8. I knew before that ios 9 had huge graphical performances issues, but i didn't know it was that bad. Since it's graphical, i have another theory which is that johnny ive asked to add invisible gui effects a little bit everywhere in the OS, and that it baddly affected the overall performance of the OS.

Huh. No such problems on my 6. In any event, if it's an easy break, it's an easy fix for them.

  Same here. I mean, occasionally there's a frame drop here and there but it happens at roughly the same rate as it did when my 6 had iOS 8.x.x. I'd say the most serious "issue" is that animations/transitions still take a lot longer than they should, and as far as I can tell you can't trigger any action while the transition isn't finished. i.e. you press home to go to the home screen and while the home screen is appearing you can't press an app icon yet.

My eyes must be getting old, but I don't see anything here. But anyway, show me that test with a full battery. How do you know the phone isn't coming in and out of a power conservation mode when you're doing your test on a 12% battery?
- robotresearcher 11y ago
  What if it is? That would also suck. They control the hardware, firmware, OS and apps. If there are glitches it's no-one else's fault.
  - joezydeco 11y ago
    Okay, then I'm definitely old. Why? Because I look upon the iPhone, or any smartphone, in whatever incarnation you are holding, to be a amazing feat of engineering. The fact it works like it does is something nobody could have forseen 10 years ago. And here we are bitching about a glitch in a transition effect. You need some perspective, brother.
    - robotresearcher 11y ago
      While I agree totally with that sentiment in general, the topic at hand is an apparent regression in performance despite improved hardware. My perspective is that I will enjoy the wondrous functionality more without glitchy transitions. Get them right or turn them off. You can call it bitching, but fit and finish is a major part of the apple brand that people value.

      1) They were mocking their competitor in this same area for years. 2) They explicitly praise improved user experience and performance enhancement for their most recent iOS shipped 3) These issues weren't on the iOS prior update. So, bitching ? No thanks my friend, I just want something that was working as advertised before fixed. If I wanted frame drops and stuttering, I wouldn't pay 800$ for a phone, but get a 100$ Android phone (which at modern hardware doesn't even have those issues anymore that are so apparent). Stop excusing companies.
