I don't think fast charger will degrades the battery as much as people think, but the external factors will.

Fast charger will indeed effect the life of battery to some degree but not significant as external factor and the trade off is easily accepted.

As the charging rate increases, heat is the main factor that need to take care of while charging.

my XS after almost a year using 18w fast charger, the battery ages beautifully.
