Two things about iOS 12 that I think speak volumes:
It’s available on all of the same devices as iOS 11, going back to the iPhone 5S. Apple has long been good at issuing updates for several years, but the iPhone 5S is easily the longest-supported iOS device.
Not only does Apple continue to update older devices, the headlining performance features of iOS 12 are specifically targeted towards improving devices they no longer sell.
The narrative that Apple deliberately makes older devices obsolete through software updates has always been fictional, but moves like these underscore how untrue a notion that is.1
They also reiterate just how poor Apple’s initial response to iPhone battery and performance issues was. ↩︎
