    I am opening this thread to gather the 6S users that have installed the iOS 11 GM.

    What is your experience. Laggy? Normal? Fast?

    The performance is not very bad I should say. There is some lag sometimes opening an app but I expect to get better with the .1 version.

    All good here after the first hour during which my photo library processing/memories scanning slowed everything down, stuttering animations & dropped frames. Fine returning to the home screen from within an app, swiping between screens. CarPlay behaved as per iOS 10 this morning. Carrier and WiFi connectivity worked without issue. Battery drain so far this morning has been in line with what was usual under 10.3.3.

    Twitter has occasionally taken a second or two to become responsive after launching, but so far this is the only app I’ve had stutter. Upgraded to iOS 11 GM directly from vanilla 10.3.3.

    I have SE, its the same cpu soo... Its okey, but im not happy with the perfomance. I like it when my device is fast and responsive. Downgrading back to iOS 10.3.3 and staying there untill 11.1

    What I have found is that if you close down all you apps then it becomes a lot snappier. You may well have apps that are not compatible with iOS 11. Hope that helps :)

    I’m getting stutters and lags when unlocking my phone, switching apps or going back to the home screen. Also my battery life is bad. I dropped 10% battery with 30 minutes of usage on my home WiFi. I restarted my phone and it dropped another 9% in the restart.

    Laggy, stuttery. iOS 11 GM 6s Plus.
    Great features though.

    Can count me out. Happy with how slick the 6S Plus feels and it took a while to get there.

    You can see some issues but only if you're looking for them. The controversial 3D touch lag is very real, and there are some times when animations just stutter. I am going to just stay on iOS 10, and use iOS 11 when I get a new iPhone

    It's intentionally bad performance and battery if apple wants people to buy new phones.....

    I watched the video. Seems like other than the power-on process, the 6s on iOS 11 seems slightly faster in most respects.

    I tried to do a benchmark test using the Antutu thing and i got a significantly lower score.

    But other than that, I have to say that so far performance has been great :O

    I had a slight lag at times when I first upgraded to 11 GM when I simply upgraded over WiFi.

    Then I did a clean install, and restored my iCloud backup. Since the clean install, I haven't seen any lag except when opening the camera. Previously I was seeing lag when using the Home button.

    No significant issues. Been using 11 since beta 2. Pleased with GM.

    Done with MacRumors, the trolls have won
    They're doing a terrible job at implementing "intentionally bad performance":

    And for what it's worth, my almost three-year old iPad Air 2 still runs extremely well under iOS 11.

    I never believed this in the past, and early on I remember things improved “sometimes”, things got faster, easier, now it never feels that way.

    I still don’t think they intentionally make it worse, but they probably feel why work your butt off to make it even faster. So probably they do what they can to get it close and say that’s fine.

    They certainly work the hardest on the current hardware and probably do not want old hardware to feel faster or better than the new hardware of course.

    So I guess more or less I agree.

    I have iPhone 6 Plus, should I just stay away with iOS11, BTW is there any major feature available on iPhone 6 Plus? I thought it is too old to get anything new on it but slow down the performance. Please advise.

    That would make sense if Apple stops selling he 6S, but they still do.

    Like with any new OS releases, I would wait till a .1 update. No point in rushing to a GM release just to complain.

    I upgraded my iPhone 6 plus 64GB to GM version yesterday and everything is OK. In the beginning, I mean right after reboot, it was really slow(maybe re-indexing or something else) and then after it was fine and made more room for me.

    No complaints. Here and there I'll see a stutter but I expect that this is going to get ironed out. But for day to day use, it really is not a problem on my 6s (64GB). Battery life is excellent. I think there are some inconsistencies though as Apple Music, if I am streaming, seems to use a lot more battery than it used to. So there are still some smaller issues.
