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.
I actually have really fond memories of Sabayon, the community was really nice. It also served as a good gateway into Gentoo by giving you a pre-configured usable system, including its binary package manager, but also gentoo’s emerge (not that you should use both at the same time).
