That's got to be a really tiny field. I have a remarkable, and can use it for weeks before charging it. Broadcast energy, as you describe, is relatively expensive, because there's a drain whether or not there's an active sink; and even so, that's crazy.
How does that work? It detects the touch of the pen, since it doesn't react to anything else. Is there a conductor on the surface of the screen?
Personally I have huion H1060P which doesn't have screen and has battery free pen. The pen is detected some distance from the surface and the same goes for the pressure on the tip and button clicks on the pen. Pretty interesting.
