It's not "a bit more repairable": it makes it repairable for people who would not be able to repair a mainstream phone.
I have many friends who never repair their phone: as soon as something is broken they buy a new one, because the repair price is often very high. With FairPhone, you get 5 years of warranty and after that you can repair it yourself at a low price.
If some people can repair their FairPhone instead of throwing their mainstream phone away, then that's a win.
I had my local Apple store replace an iPhone battery for £69. If I Google "Fairphone 5 battery" it comes at about the same price (£45 - £65) just to get the part.
Of course, warranty won't cover aged battery or damage (which probably are 99% of repairs) in any case.
