> People are talking about "lag" and performance, as if this was a "the system can't handle it!" issue. This is a misleading description. Lag doesn't necessarily have anything to do with performance. I really don't think people are talking about performance at all. No one would seriously think that a modern smartphone could be dwarfed by a 35 year old calculator in terms of raw performance.

I could seriously think that. A pocket calculator has a ~200KHz processor and an LCD with an update time of maybe 10ms. A single digit calculator operation like addition would be a few clock cycles, so say a total time of 15ms with output buffering. A 60Hz monitor refresh rate is already worse than that without considering the framework stack.

Do you have a source on that clock speed? I've been trying to dig up info on pocket calculators for a while.

(The last time I brushed-but-didn't-quite-hit some interesting info was in https://news.ycombinator.com/item?id=15136939, which I quoted (very tangentially, as a footnote) in https://news.ycombinator.com/item?id=15153262.)

No they're not. The linked thread is literally discussing what you describe as "the actual issue".

Unless you were talking about the discussion here on HN? I haven't read most of the discussion here yet. I just wanted to point out that the Redditors get it right just fine, since there's a lot of unheeded shitting on Reddit on HN (has always been the case and I think it's sad. HN has got its own community smells, but at least I hardly ever see Reddit dumping on HN and when they do it's in good natured fun poking and not vitriol like here) (btw your remark wasn't vitriolic, but others are very much so).

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 th…

>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 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 th…

No—even at face value, "sprinkling wait()" does not slow the CPU, it slows the software running on the CPU; if you then manage to obtain 100% for your thread, that does not disprove that Apple has not added `wait()` anywhere in their code. In their code—software.

As soon as I upgraded my 6s to 11, I saw performance seriously degrade. It takes -seconds- to bring up the iMessage editor. 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. Or... maybe they are running every key stroke through the new Azure-enabled Cray com…

Strange, I see little to no difference on my 6S. I was considering getting an X, but since my phone still handles iOS 11 perfectly, I don't see any reason to upgrade.

I'd try restoring my phone if I were you - that fixes these issues for a lot of people.

TIL some people think berating your employees when they do a mistake is a good way to run a company. WOW! It's just so wrong at so many levels, I don't even know where to start. I'll leave a link to this video: https://www.ted.com/talks/brian_goldman_doctors_make_mistake...

This is pretty unforgivable. It's like ok great, I'm paying 50 people to make an app and NONE OF THEM EVEN USED IT?!

Testing is for pussies. Apple is a courageous company. Courageous. Very courageous.

Would you please stop posting unsubstantive comments to Hacker News? We're trying for a somewhat higher level of quality here.

This. My 6 Plus is barely usable now, to the point where it is annoying the hell out of me. On iOS 10 i was fine with the 6 Plus and thought i could easily use it another year, but right now it's barely usable. I compared loading a banking app on my 6 and my colleagues 7 (closed it before) and the difference is astounding (2-3 seconds slower). Also everything is just laggy including typing and taking photos.

Odd, I have a 6s Plus and I haven't had any issues after upgrading. Sounds like it's hit and miss. I wonder if they changed the hardware during the production lifetime.

6S has the A9 processor, the 6 has the A8, maybe that makes enough of a difference for it to not be that bad. I will also try the complete reset though.

Your solutions are a little off the mark. Treating the animation as the problem is merely treating the symptoms. What needs to happen here is pressing the button needs to immediately register the press elsewhere in the code. The UI animations and the button tap should be decoupled entirely. Then the user can tap away as fast as their heart desires and only the animations are going to continue on. That’s an easy probl…

My professor likes to tell this story about keyboard buffers that I never quite understood. Basically, in this old time terminal setup he would start typing the password before the prompt showed up or something and when it did, it would just sail through. Sort of like how I can apt upgrade while apt update is still running but fancier and a couple of decades before...

> Sort of like how I can apt upgrade while apt update is still running but fancier

You can link two commands together with the "AND IF" operator

    sudo apt update && sudo apt upgrade

Furthermore, you also have `||` which is the logical or, and also `;` which is just a separator which doesn't care what happend to the command before.

Seems you are cutting and pasting, but Apple gave away free bumpers with the 4, so yes, it was an issue.

What's the alternative? Android, especially Samsung infested bloatware, is substantially worse. The touchwiz upgrade prompts are WAY more annoying than ios ones. Plus the constant Samsung login junk. And then there is the heavy google integration that requires a google account for almost everything.

Except it isn't worse. Not anymore anyway. Any and all notifications just go up top and don't prevent you from using the phone -- even if someone calls you. My 3 year old Sony Xperia Z1C that I only use to for testing lets me jump into whatever app I want as soon as it starts immediately even though I can see there's like 50 notifications to go through. But I can do that when it's convenient for me. My main problem i…

Samsung OS is always slick until a year later when they drop all support for it, and the force installed apps start to install adware. This has happened on every Samsung I’ve owned.
