Not sure why you think nobody is talking about it for high power devices. It’s already in development for some kitchen appliances and being discussed for EV applications. And wasteful is wasteful, regardless of localized scale. Multiply that “negligible” loss per phone by the number of smartphones in use globally and tell me how negligible that number remains.This is a slippery slope fallacy. Nobody is suggesting to have high power devices to go wireless. There is no benefit in having a wireless washing machine or tumble drier, and they absorb several, several times more energy than an iPhone. In fact, the energy absorbed by an iPhone is negligible, so a 10% loss is even more negligible.
