Wired is more efficient, you can pick it up and use it while charging, and the cable usually comes free with the phone. What is the point of wireless charging pads?
If someone claims to care about the climate, then using wireless charging makes them kind of a hypocrite. I asked ChatGPT to do some back-of-the-envelope math - so take these numbers with a grain of salt - but if everyone in the world switched to wireless charging, it would increase global energy consumption by around 12 TWh per year. That’s roughly equivalent to the total power usage of a small country like Iceland.
Seems like a massive overestimate; my quick calculation got a number an order of magnitude lower, and that’s assuming 60% of the world’s population fully charges a smartphone every two days.
Surely that would very a lot depending on where they get their energy from? Even the most measly household solar panel can deliver 10W to a charger, in which case, the energy impact would be negligible.

Huh, I never considered the inefficiency to be that bad
