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?
Tablet pens are powered by a changing magnetic field generated by the tablet (induction). They only have power when near the tablet.
That’s pretty smart.
Thank you.
You’re welcome.
Some require actual charging so I can see how someone might get confused when switching to a different model
They often have a small capacitor that feeds them and acts as a tiny, couple of minutes long, battery.

It’s probably not on when there’s no pen nearby. You can automatically detect those things
