Having the latest iOS is not the same as having the latest iOS on the latest hardware. As years go by, you get less features or less snappier experience.
When my iPhone 6s received iOS 15, it didn't get the coolest stuff and the device performance was already less than decent. Even if the iOS itself wasn't slowing it down, the apps for iOS were made with expectation of higher performance.
As opposed to tossing an Android device into the landfill because it doesn't get any software support at all after a limited time?
> Six years is an awfully long life span for a mobile device, and certainly puts the 6S in the running for the longest supported phone to date. The iPhone 5S was five years old when it got its last OS update with iOS 12 but wasn’t eligible for iOS 13. On the Android side, Samsung has made recent moves to improve its device longevity by offering four years of security support for some of its phones. But six years of OS updates and security support puts the 6S in an entirely different league.
Apple is definitely doing great. It just would be cool of them if they provided option to unlock the device so maye go back to an older iOS or repurpose it for something else.
