That's kind of unfair, the iPhone 4S was released on September 2011, so it was supported 5 years since release. It went through 5 (!) major releases of iOS, from 5.0 to 9.3.5. If you buy a phone that you know is already going to be obsoleted soon (it's not like Apple makes its release schedule a mystery), you should assume it will have less support than the latest model.
