The issue is supposed to be resolved with the next update. It get stuck on with the screen off, and wont respond to buttons. So thus it can't be turned off, and because it is not off, it can't be turned on. Battery pull is the only option, unless u would rather wait for it to die and then charge it to the 5% required to power it back on.
The answer is 42. Hell, even Siri knows that.
Oh, wait, you mean to tell me you need to know the question now?
Well, I can't answer that.
