You make several good points. Honestly, I know we all like fast charging, but at 10w (where I think wireless will standardize eventually) the charge is fast enough. With bigger batteries and more efficient OS, I think we’re all likely to be able to charge at this rate without much inconvenience.
The inefficiency is troubling though, that’s a lot of power to lose over the lifetime of a phone. I can only guess they will adopt a new wireless standard before going all in on wireless.
