There's a healthy used market for iPhones because they indeed do last long, and Apple provides many more years of software support than cheap Android manufacturers do.

IMO when it comes to electronics with little to no moving parts it's almost always better to buy used quality than cheap new crap. An iPhone that has lasted two years without failing will probably last 5 more without anything else than battery needing replacement. Mid-range Android phones often aren't bad either except for lack of long-term updates.
