Is Fast Charging Killing the Battery? A 2-Year Test on 40 Phones (www.youtube.com)

TL;DW: Fast charging over 2 years only degraded the battery an extra 0.5%, even on extremely fast charging Android phones using 120W.

And with that, hopefully we can put this argument to rest.

Not doable without some very expensive addons to your house - like IR charging from ceiling

Everything is always charged when Im inside.

That's living in microwave, I'd say its not going to ever happen

I'm fine with infrastructure overhaul. We build new houses every day.

We just need to be clever enough to do it without cooking ourselves

Wifi is limited to ~100 miliwats of power, and what reaches you and your phone is in range of microwats or even less. You can't charge your phone with it.
