My last phone I kept for about 5 years. I had two issues:
software support had ended
the battery was severely degraded
fortunately there was a local shop who’d replace the battery (it wasn’t a fairphone so I couldn’t do it myself). If it wasn’t for the software support I’d have gone that route and would be still using it now. It worked perfectly well for my use case. Unfortunately, I ended up retiring the phone and getting a new one.
