Nice article that actually does some analysis and also points out the major problems with performance that did and do exist with iPhone 4s on iOS 8-9 and the bad experience that is iOS 10 and iPhone 5

This article is very poor - it’s spin

Arstechnica have a read.....

The iPhone 5 and earlier did not have 64 bit SoCs. That's the most significant dividing line when it comes to iOS. The 5s was the first 64 bit SoC and isn't even in the same ballpark as Apple's more recent SoCs for single and multi core performance, but it still can run iOS 11 quite well.
 
I, do not, believe this, for one single bit.


- Benchmarks only show potential driver and raw CPU/GPU performance, but it does NOT show intentional code in the OS that would look like (Simplified, but the idea is what matters)

if iDeviceModel < %whatevernumber%
{
goto Function MakeYourDeviceSlowAsHell
}

MakeYourDeviceSlowAsHell
{
'Add some random malicious junk code to rum in the background or just randomly sleep between execution of code'
}

If you really think there is “code” like that on the OS you are delusional, believe me.

Please go find an iPhone 4S running iOS 9 and comeback here and tell us how it goes.

If you think 4S on iOS 9 is a good experience..... wow....just wow...

It’s not actually. Though people don’t look at facts. You may choose to ignore the changes.

https://arstechnica.co.uk/gadgets/2017/09/ios-11-iphone-5s/

If you do research, you will find this “benchmark” is BS, there has always been a history of performance issues with iOS upgrades. Hardware benchmarks are meaningless in relation to os user experience

These are the conclusions of the author of the article you link to:

«But as I do every year, for most people I would come down in favor of updating. The iPhone 5S is slower with iOS 11, sure, but it's not as slow as the iPhone 4S was with iOS 8 or 9, or even as slow as the iPhone 5 is with iOS 10 most of the time

So it seems like Apple has optimized iOS11 for older devices.

«The iPhone 5S gets a little slower, but that's how it goes when the oldest hardware that runs an operating system is only 20 or 25 percent as fast as the most recent hardware»

So it's not like it's due to some Apple mischievous behavior, it's just how things go.

My experience:
My wife's 6+ has gotten quite slow - already on IOS 10 but even more now on IOS 11 so almost unusable.

I have now done a complete restore via iTunes with IOS 11.0.2 and not yet played back the Backup.
In other words it is a completely empty phone with a fresh install. And it is still slow! Just scrolling from one screen to the other is sluggish. I am not one for conspiracy theories but it still feels like a deliberate slowdown of the phone to 'motivate' people to upgrade.
 
Android users may have to wait longer for updates but when they do get them, the devices actually improve in performance. Android updates ensure that even the lowest denominator will have smoother performance with updates when they do come. The artificial slowdowns of iPhones/ipads has been going on for years and the GPU and CPU has always been so-called ahead of everyone else yet it doesn't stop the slowdowns and stutters.

This is flat out untrue. My Nexus 7 and Nexus 5 would say otherwise as updates made them unusable. Additionally, few Android devices get more than 2 major updates. One of the reasons I left Android was because Apples supports their hardware longer.

when a device like the 4S or 5 is performing badly on an iOS version? Why is the user locked into that experience and now allowed to downgrade to a better experience ?

Point here is , there is historical evidence where performance has been poor, and the user upgrades in trust , with expectation that upadates will resolve the issues to find out they are locked into the poor performance and not allowed to rollback.... its apple that chooses not to allow you to rollback, it's really a trap in some cares. Know plenty of people with great performance on 4s on iOS 6 and 7 who did not upgrade....

No. You may find that CPU performance stopped being a bottleneck from the 5S.

Same goes for macOS and windows, CPU performance stopped being a bottleneck a long time ago.
 
Apple does slow older devices but not with just software updates. You can experience it with any MacBook. But the way software detects older device is quite interesting - with battery cycles. Get a quad core MacBook Pro from 2011 with original battery, which is still faster than half of the current MacBooks according to specs but.... it will be super slow even plugged unless the battery is changed.
 
I've just rerun the Geekbench test now, because I felt it suddenly got much slower with iOS 11.

No conspiracy theories need apply.
No fake news sourced from, and believed by, numpties.
But for a real article on the slow-down of the lowest iPhone on the iOS totem pole read ArsTechnica.

This story won't play well in the MacRumors.com community--it completely invalidates all the conspiracy theories and complaining.

There is nothing to "invalidate" what I know. Three different platforms I've had to roll back. Update made them unusable, rollback brings it back. Each junk update was given two weeks of use. I know what I see. You don't.

Benchmarking company Futuremark recently set out to debunk long-running speculation that Apple intentionally slows down older iPhones when it releases new software updates as a way to encourage its customers to buy new devices.

Starting in 2016, Futuremark collected over 100,000 benchmark results for seven different iPhone models across three versions of iOS, using that data to create performance comparison charts to determine whether there have been performance drops in iOS 9, iOS 10, and iOS 11.

The first device tested was the iPhone 5s, as it's the oldest device capable of running iOS 11. iPhone 5s, released in 2013, was the first iPhone to get a 64-bit A7 chip, and iOS 11 is limited to 64-bit devices. Futuremark used the 3DMark Sling Shot Extreme Graphics test and calculated all benchmark scores from the iPhone 5s across a given month to make its comparison.

The higher the bar, the better the performance, and based on the testing, GPU performance on the iPhone 5s has remained constant from iOS 9 to iOS 11 with just minor variations that Futuremark says "fall well within normal levels."

iPhone 5s CPU performance over time was measured using the 3DMark Sling Shot Extreme Physics test, and again, results were largely consistent.

iphone5scpuperformance.jpg

Charts for other devices, including the iPhone 6, 6s, and 7, show some mild dips and increases when it comes to GPU performance. In the iPhone 6 and 7, GPU performance is up compared to previous-generation versions of iOS.

cpugpuperformanceiphone67-800x821.jpg

CPU performance across those three devices has dropped slightly, something Futuremark attributes to "minor iOS updates or other factors." "A user would be unlikely to notice this small difference in everyday use," says the site. Based on its benchmarking comparisons, Futuremark claims "there are no signs of a conspiracy."Raw CPU and GPU power across devices does not offer a complete picture of performance on an older device that's updated to a new operating system, however, nor are benchmarks an accurate measure of real world performance. Apple may not be deliberately slowing down older devices with its software updates, as some have speculated, but there are other factors to take into account.

New features that eat up more system resources can make a device feel slower, as can more system intensive design elements and other tweaks and changes designed for newer devices that are more powerful.

Apple's operating system updates also introduce more advanced APIs and technology for its newest devices, leading to built-in and third-party apps that are aimed at more powerful devices and may not be optimized on older devices, resulting in an older device feeling more sluggish than a newer device following an iOS update.

Sometimes, there are also early bugs in the software that need to be worked out through additional updates. For example, we've seen complaints of app slowdowns and performance drops from users who have installed iOS 11, issues that may be resolved as Apple tweaks and updates the iOS 11 operating system.

Article Link: Apple Doesn't Deliberately Slow Down Older Devices According to Benchmark Analysis

This is just untrue. None of this accounts for the "eye test." I've had three different phones become unusable due to these updates. I've rolled them all back and the difference is clear. All were give a two week trial so yes, I've waited for the indexing. Sorry to use a Trumpanzee line but this is fake news. I'm finally going Samsung.
 
I have an older iPhone 5S and I can certainly confirm that there is no slowing down of performance. And I certainly use my iPhone for LOTS of applications.
 
It should, there is now indisputable evidence that these disgusting allegations made about Apple are completely untrue.

It is still true as they always used planned obsolescence to cut older iphones out of the equation with each iOS update. The OS gets slowed down when the RAM of that current device can't handle the newer OS iteration due to new feature creep.

That's how they manipulate you to upgrade to the more expensive device.
 
They should test it on iPhones used in the real world. I would bet that the slowing down has something to do with the memory being filled with thousands of pictures and videos. Of having 400 separate pages open in Safari, having hundreds of apps installed, and a crappy internet/cell connection.

Although it is a good test to prove it isn't obviously coming from Apple in that configuration. I would say that car companies were able to cheat on emissions testing by knowing when it was being tested instead of when it was in the real world.
 
Wait, please tell me this isn’t how it looks. A reputable benchmark company hasn’t repeatedly run the same benchmark on the same hardware and expected different results, have they?!

That is quite literally the definition of ‘insanity’. A worry for whomever came up with the idea, you might say.

yeah. This article reeks of paid sponsorship.

everytime a new version of iOS is released, people do complain that their phones seem slower, laggier and less responsive than before. it's not everyone, some people are just encountering bugs, and others are encountering software that just requires more from their hardware.

Either way, instead of Apple seemingly taking responsibility and trying to explain why... Because iOS11 DOES MORE **** than iOS10, and therefore uses more cycles and memory, suddenly out of the word works are these reports "Apple doesn't artificially cripple their CPU's, SEE, ON benchmarks they still perform exactly as intended!"

that's not the point. it's a red herring. it's like a magician waving his arms to get you to look elsewhere. it's a diversion. Yes, the A7 runs the same speed as the A7 did when you bought he A7... and so on and so forth. But they still don't address that in real world use cases people ARE encountering worse performance on iOS11 than with iOS10. not everyone. but many.

this only tests 2 aspects of performance. anyone with common sense knows Apple doesn't intentionally cripple hardware to force upgrades

they did however for the longest time provide the bare minimum in hardware requirements for the time with the expectation that in the future, buying new hardware will get around those limitations. When we talk about how much RAM a device has for example and we're looking at 4-8gb on phones, this isn't because we truly think we're using all 8gb all the time now. But it means in 2 years, if I'm not ready to throw out my phone and it's got 8gb of RAM, a new OS release isn't likely going to slow down DUE to their being restriction on RAM.

While everyone else was putting 4gb of RAM in their phones, achieving all day battery lifes, and preventing limitations of the smaller ram space. Apple kept insisting on 1gb. Tell me, which phone is going to feel snappier on a newer OS that uses more RAM? or newer web browsers that might have more memory usage due to larger / more complex web pages? RAM is one place you should never skimp on if you can avoid it. and Apple was skimping on it. why? we could speculate that, but my guess is to keep costs down for them at the time AND provide enough for now, but have no future proofing in mind.

Wow.......conspiracy theory.....maybe

Artificial slowdown may have become natural slowdown by all indications. iOS 11 is truly unoptimized.
 
I don't believe this Apple sponsored propergander. There are so many people across the forums saying the same thing. My own expereince is ios 11 is noticeably slower on my 6s plus. I've compared this to people running iOS 10. It's a very obvious difference despite what charts, research analysts, data experts and anybody else in the world say.

And yet my iPhone 5S is just as useable with iOS11 as it was with 10 or 9 or 8 or 7.

Still works as fast as it ever did.

Still as responsive as it ever was.

So I’m calling shenanigans on this whole “my phone is unusable thanks to iOS11” nonsense.


ahh the defense "it doesn't happen to me so it can't have happened to anyone else"

I like iOS11, i don't want to downgrade and I won't. I overall like the featureset over iOS10 and the new dock.

but it has made my iPad Air feel sluggish in some use cases. 10.3 was fine, 11 is not. from Apps taking 5-10 seconds to load and become usable, to the overall UI running at roughly 20fps with dropped frames.

doesn't bother me too much because i do understand the age of my device and that iOS11 brings more to the table.

But to say that it's SHenanigans and people are lying or this is nonsense experience people is having is just downright ignorant.

Apple sponsored, or "enthusiast" sponsored is sometimes hard to tell apart. there are a lot of enthusiast on the internet who will go to great lenghts (for all device makers, not just Apple) to come up with weird defenses for odd choices and regressions. This is one of those weird ones that the article makes no sense and is weirdly timed

similar to the one posted today about "now that Apple's doing faceID EVERYONE ELSE IS DITCHING FINGERPRINT SENSORS!@!!"... based on what? that's ludicrous. there's been zero evidence of such movement or behaviour in the market, especially since face unlock tech isn't new and has never caught on before. Sure Apple doing something usually helps set trends, but do you think Samsung et al are suddenly going to drop fingerprint sensors if they don't have to?

Apple has always been about providing users 1 way of accomplishing something. And they insist that way is the best. so it makes sense that Apple drops one tech in favour of another. But that's not a trend/behaviour we see from the other guys who tend to try and cram as much in as possible. (with the exception of guys like Essential who, seem to be out of touch as is)

A result much higher than your claim for an iPhone 6 (that is faster).

Actually your video just demonstrated two things: minor differences going from 10 to 11 and almost exactly the same Geekbench result, even if you claim to have CPU throttling (absolutely untrue according to my knowledge).
