SiC is not a good fit for anything under ~100-200V, it's just not what it is designed for.
GaN makes more sense for consumer electronics, that's why it's popping up in a lot of devices, even if prices right now are too "high end" for most users.
As for phones, watches, etc..:
1- These technologies won't be as dense as standard silicon for quite some time (if ever.
2- We've had big swings in both efficiency and battery capacity several times already, but it works in the same way internet speed works. Power-hungry features grow with increased efficiency in the same way websites grow in size with increased internet bandwidth.
