I was a bit surprised until I kept reading…

Of course I charge it every night!
 
So far every night. Got down to 59% the other day. I just like to keep them topped off, not sure why, but I do.
 
Normally leave it in the dock to charge over night, but that does depend on how much battery I used during the day. If it is above 75% I'll usually just leave it. To tell you the truth, I've been using my iPad less and less and going back to my MBP to do most of my work.
