Genuinely wasn't meant to be a pointed criticism. I was curious to learn more about the use, which I just found different to what I'm used to.
I guess in this case I would read "wastage" as the reduction of available power over time. That is, the power was wasting away. Rather than the "waste" of power (frivolous use) by too many CPU cycles.
