Why doesn't Apple warn that an iOS update may slow their device?

Apple doesn't warn you as such.. They don't need to when no one reads the footers.

"3. Requires iPhone 6s or later, iPad Pro, iPad (5th generation), iPad Air 2 or iPad mini 4."

Anything prior is at your own risk,, i would have thought that would be easy enough.... Its the same with other iOS versions as well. That doesn't mean it won't run, but u'r own your own if its slow.

Actually, Apple should warn you on the decice because no one reads the footers

That footer only refers to Siri's ability to automatically put certain items on your calendar...

In my experience, Apple only cares about their latest model. They'll make damn sure that the latest OS runs perfectly on their brand new devices, but they don't seem to try very hard at optimizing the latest OS on the older devices.

I'm still on 10.3.3 on my iPhone 7 Plus because I like the animations better and I refuse to let the UI lag on my iPhone just because of a few new UI changes on iOS 11.

Apple took forever trying to nail down the close-app animation on the iPhone 7 series, and they finally got it right... only to change it again in iOS 11 and in my opinion it looks really weird now. I liked how all of the apps sort of zoomed out to the home screen. Now they kind of fade in from the background as the forground shrinks. It just looks very odd to me. The other way made more sense visually... like the apps are returning home.
