iOS 9.2.1 rendered my iPhone 4S useless

[Altis]

I put my 4S back on iOS 6 and it runs better than my iPhone 6. Much faster.

iOS 7 and 8 made my 4S run terribly and the battery would be done at anywhere from 5% to 45%. "It's hardware" they all said... but back on iOS 6, it runs right down to 1-2% before turning off.

That has been happening to essentially all kinds of technology, especially related to computing, for ages.

My old MacBook Pro from 2009 on El Capitan is just as fast as when it was released.So,no,it's not happening to all kinds of technology,noT even amongst Apple's products is it consistent

Were you already jailbroken? I'd upgrade to 6.1.3 for cheese and giggles but there's no jailbreak for 9.2.1 AFAIK.

Your anecdotal experience means about as much as the anecdotal experience of someone else running iOS 9 without any issues--since that anecdotal experience isn't something that is believable to you, the same concept could then be applied to your anecdotal experience.

Agreed. 4S is excellent on ios6. And I honestly wouldn't miss any of the so-called must-have new features that later OS's brought.

The only slow down that's unavoidable are web pages, and I'd blame that heavily on the amount of advertising code that bogs down the modern web. I'd bet if I turned off the content blockers on my iPhone 6 (that Apple has withheld from the 4S - is a block list that CPU intensive?) it would slow down as well.

Heavy JavaScript ads do universally lag the browser on all platforms. I also agree that there's no technical reason why ARM 32-bit iPhones like the 4s can't run ad blocking other than to upsell newer devices because something like Adguard runs great on other platforms on equivalently old ARM 32-bit devices.

It has been happening, but should it be happening? That's the question. It should only happen at the expense of increased functionality, but more often than not, that's not the case.

Why should a keyboard lag on iOS 9, but not on iOS 7?

Apple doesn't want to upsell you, that's the entire planned obsolescence conspiracy theory, they don't want to support certain functions on 32 bit. Big difference.
