Okay, if we're going to do the math on typical consumer usage lets talk in less worse case scenario terms, an iphone 16 depending on the model has around a 15 Wh battery, a typical consumer uses lets say 80% of their battery life per day so we're looking at charging 12 Wh per day, QI2 reports as much as 93% charging efficiency, that seems optimistic though, let's say 80% average, and let's also generously say wired is 100% efficient (it's not but whatever). This makes the math easy, we're wasting 3 Wh per day to wireless charging vs wired. Across 200 million devices, all concurrently being actively daily used and wirelessly charged we're looking at 600MWhs. That's quite a bit, it's about enough to get a single Boeing 747 3/4ths of the way across the atlantic ocean. Or two private jets a round trip. There are about 1400 transatlantic flights per day on average. This would use about .0007% of the worlds electricity generation.
