What I don't understand about this is why you don't charge while not playing it... then play it while it's charged. If this is not satisfactory there are two options.
#1 You're too lazy/forgetful to charge it after playing it (like when you get home).
#2 You are regularly playing it for 6+ hours without access to an outlet.
Sprawl on the floor all you want... and when you're done playing, plug it up. Then you'll have all sorts of freedom the next time you want to play it.
I see... And what have the ladies to say about that?
