Not sure. I think I've seen figures of 10%.

It's not the personal cost, but the global increase in demand when we
should be doing literally everything we can do reduce our energy use.

Wireless charging induces increased heat in the battery which we know can
reduce the lifetime of batteries. It may be minimal, but I do find that the
phone struggles to reliably last a day. So any loss in capacity should be
avoided.

It's a personal choice.
