"900 million active iphones in use" - CFO Luca Maestri

14.26 Wh * 900000000 * 365 (days) = 4684 GWh/yr

46% = 2154 GWh/yr wasted energy

That's about the total energy output of Madagascar with a population of 27 million people.

There's a lot of reasons why the above numbers are wrong but I just wanted to highlight that at current efficiency, there would be a lot of wasted energy. :)

Thats about the energy demand of a single small aluminium smelter

not exactly a lot of energy in the big scheme of things

Yeah, it's not so much efficiency.. phones don't have that big batteries anyways.

I would be more concerned about charging speed and heating.

Inefficiency implies heating :)

And wow, do I love charging my phone using my laptops USB-C charger.. it's just so fast!

I don't really see the appeal of wireless charging. Faster direct charging would be a bigger win, IMO.
