Phones consume a miniscule amount of power compared to other things you probably use. Even if it is 20% efficient if is still a drop in the ocean compared to air conditioners, tumble driers, fridges, ovens, kettles, toasters, hair driers, etc.

Small changes are still small when you "multiply them by millions" because all the big things get multiplied too.

> Wireless charging is highly inefficient and wastes energy, so I hope it won’t become a widely adopted standard.

I find it rather useful with my toothbrush. While I'm very much pro environment it is not like we're talking about huge batteries here.

data could be wireless so a waterproof dustproof design is possible (look at the watch)

But you’re right: wireless charging is too inefficient and thus slow, so I also doubt they’ll really go there.

Killing one attempt to make a simpler wireless charger doesn’t mean killing the idea of universal wireless charging.
