Yes, smartphone camera's are awesome now, but it's sad an awesome product like that will be thrown away after a year of use.
Even an iPhone 6s from 2015 with a new battery is faster than most low end Android phones and it is still fully supported.
(for context, my prior upgrades were in a more lenient trade-up program, which by coincidence resulted in me keeping up to date. not trying to pretend like avoiding a one year upgrade is some major sacrifice, its just what happened)
I've had some apps that stored files within them, and the app was no longer available for a higher version of iOS that a new phone shipped with. Would have been royally screwed if I had sold/traded in my prior phone because I wouldn't have immediately noticed except when I needed it.
