> 2. The iPhone 6S, released in 2015, is still supported by Apple. That's a 7 year old phone. iOS 13 (released in 2020) dropped support for the iPhone 6/6+ (2014) and 5s (2013) so 6 years and 7 years respectively.

If you include years where you get a security update, but not an OS update, as Android device makers do, the 2013 5s got another update at the end of last year.
