I honestly feel like they make it run slower on the previous gen devices.
I don't believe that it's done on purpose as part of some grand master plan of planned obsolescence.
What's happening is just that, new versions tend to add new features. New features require additional resources, to have that feature running it has to be in RAM, so RAM usage goes up. it needs storage on disk, so disk (storage) access goes up. it needs processing cycles, so it uses more of those.
add enough new stuff to a new version of an OS, and put it on older hardware, and you will find that the older hardware, sometimes just doesn't have enough of all that. RAM, storage speed, or cpu cycles, so that the device feels slower while those extra resources are being used up.
this isn't new. anyone who was computing through the vast majority of 80's, 90's and even 00's experienced this on laptops and esktops regularly. Constantly having to buy new hardware just to run software / games without bogging down or slowing. Heck, we all remember how big the jump from XP to Vista was on system resources.
What bother's me more, is not that the newer OS's need more resources. Is that Apple doesn't let you downgrade should you encounter issues with the new OS. ocne you upgrade, AFAIK, thats it. you're stuck on a slow performing device unless you buy a new one. If it were a computer, you'd just wipe it and reinstall your old OS. heck, you can even do that with Android if you're so inclined. It's only really Apple that has these limitations in place.
I would like to see Apple borrow a little from Android's playbook when it comes to allowance of users to stay on old versions and still receive security updates, instead of forcing a full blown upgrade just to keep current.

I would be curious what the percentage would look like after being adjusted for devices capable of receiving the update. For both Apple and android. Especially for android I would suspect there's quite a few devices for which the new OS is unavailable.
my iPod Touch, 1st Gen is still on iOS 3.
I doubt that's calculated in this
