But they specifically did define a time: 15 seconds. It actually makes you wonder, who says the pencil will ever necessarily be fully charged in a traditional adapter? 15 seconds per half hour doesn't seem like a lot to ask, then just leave it in your bag when you're done.
I think 16 charges in the course of a working day would have a UX impact. Many of my colleagues would throw a device in the trash for that.
I'm surprised nobody's mentioned the obvious: Wacom styluses don't need charging ever. Despite having more functionality. Yeah, patents blah blah, but the point is, no charging solution from Apple is going to beat Wacom's solution, and even the most avid fans of this cluster*** have to respect the fact it's a second class solution. I've been using battery-free styluses for 20 years, and the concept of charging them at all seems like a step back In time to the 80s.
On top of that, the flyswatter charging solution is the most idiotic thing I've seen from Apple by a long way, and possibly the most idiotic thing I've seen on any mobile device since Apple vs Samsung et al became a thing. And I cannot believe the same people who designed MagSafe designed this with a straight face. It's almost like the brief was to achieve the exact opposite of MagSafe, dragging devices from desks and breaking everything which could be broken in one satisfying impact.
I don't believe anyone's mentioned this yet, but why the sweet **** didn't Apple design the pencil to adhere magnetically to the side of the iPad and charge from those connectors there which power the keyboard? Pencil 2 perhaps?
