It's true that raster tiles are easier to draw, but CPU/GPU is rarely the limit for performance even on (modern) mobile devices, network access then disk access then memory usage is. And using the network is one of the largest sources of power use. Vector tiles are smaller downloads, therefore they are more performant.

Wall time CPU profiling is just not that useful anymore and yet it's the only thing most people ever think about for some reason.
