> Besides all that, wired charging is not nearly as efficient as you think. The charge circuitry in your phone is optimistically 80-90%. The wall adapter can be anywhere from 50 to 90%, and scales pretty closely to how much you paid for it. Efficiency also goes down with faster charge rates.

The costs of wireless are on top of all of the costs of wired. You're not getting away from battery management just because you're using the air as a very inefficient cable.
