You know there's an in between, right? Like you don't HAVE to upgrade your phone every year or every time a new one comes out. They support software upgrades and security updates on older devices for a little while. I upgraded mine about a year ago and have no plans to upgrade again soon. My last phone I had for about 3 or 4 years and it still worked fine (Also I didn't "throw it in the trash" I traded it in for cash towards a new phone). Had a newer OS than your phone does, too.
