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?

  You have no choice with 6S, since it shipped with iOS9. 9.0.2 stutters too.

    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.
