@JohnPhilpin The main reason I can think to use the existing headline is if you assume that people are more likely to ask that particular question, rather than search for "powering the keyboard" or anything like that.

I'm not sure the difference between powering or charging matters enough, especially when for most people they just want to check how they do a thing. Given that, I would side with the people in favour of the headline especially since charging is certainly the commonly known action when it comes to these devices.

If it said "You Won't Believe This Terrible Secret Apple Is Hiding From You" then sure, I'd be perturbed.
