This has frustrated me to no end: my iPhone 4s is still in brand new condition and if only Apple would allow me to downgrade to iOS 7 or so, it would be roaring fast, albeit limited in what websites it can handle or what app versions it can run. But instead it's stuck on the newer iOS 9.x, which turned it into a paperweight. It's The Peter Principle for tech devices: a competent device will keep getting upgraded until it becomes unusable at its current OS. https://en.wikipedia.org/wiki/Peter_principle https://en.wikipedia.org/wiki/Peter_principle
