> My immediate thought was that Apple had liberally sprinkled wait() into the iOS 11 code base so that I'd feel like my ole A9 CPU just wasn't cutting it any more and I'd realize, as they do, it's time to upgrade. That was actually recently debunked by Futuremark https://www.futuremark.com/pressreleases/is-it-true-that-iphones-get-slower-over-time https://www.futuremark.com/pressreleases/is-it-true-that-iph.... Important excerpts found at the bottom of the page: > Our benchmarking data shows that, rather than intentionally degrading the performance of older models, Apple actually does a good job of supporting its older devices with regular updates that maintain a consistent level of performance across iOS versions. and > That said, there are some factors that might affect people's perception of performance after updating an older device with a newer version of iOS. An update might add new features that use more resources or require more processing power. New apps developed for the latest models might not run as smoothly on older devices. Conversely, apps designed for an earlier version of iOS might not take full advantage of optimizations in the latest version. And then there is always the psychological effect of knowing that there is a new and improved model available, which can make your own device seem outdated.

What is debunked? That the CPU has not changed during the upgrade? No shit sherlock. Synthetic benchmarks tell nothing of the end-user experience. Does Apple sprinkle wait()? No. Does the system become more and more complex and Apple taking less time to optimize because it runs “fine” on the [latest - 1] hardware? Yes.

  Technically the 6s is now [latest - 2] hardware. X/8/8+ have the A11 Bionic; 7/7+ have the A10 Fusion; 6s has the A9.

    Exactly what I said. It runs "fine" on 7, while it runs slow(er) on 6S.

      iOS 11 runs fine and just as fast as iOS 10 on my SE. It sounds like you are experiencing a bug.

        Aren't there, like... 3rd-party chat or emoji apps or something now? I don't use any of that stuff, but if only some people on 6-series iPhones are experiencing a multi-second delay opening the iMessage editor, my first guess would be they have some of those installed and one or more of them have shit the bed.

      Ah, my mistake, I was taking the scare quotes to mean you were complaining about it on your hardware.

    Tired of people bringing up that "article" and the sensationalist media headlines. All that articles shows is that the CPU, given 100% utilization, does the same result as it did on iOS 10. Really surprising for sure. So what was the point of you posting that article? People saying "Apple is slowing my device" don't actually mean "the CPU has become slower". There goes the entire premise that benchmark. The CPU is the same—the software is less optimized for older hardware. The net effect? The software runs slower (and in some cases much slower) than older versions of the OS. The real rebuttal of "slow" claims should be to look at the added features and security and discuss whether such trade-offs are worth the reduction in performance. For example, to make the user's data much more secure, Apple puts a lot of mechanisms behind XPC, which is inherently slower than mere API calls. These slow the system. Are they worth it, for the security benefit? That's the productive discussion we should be having.

All that articles shows is that the CPU, given 100% utilization, does the same result as it did on iOS 10 But that is LITERALLY what people were accusing Apple of doing, actually slowing their devices to make them buy newer models. There might have been less conspiracy-esque claims, but jesting they were "sprinkling wait() calls in the code to make me upgrade" is not in that category - so I disagree with your claim that people weren't meaning that. Anyways, this discussion has derailed, so I'm just gonna leave it at that.
