    I closed my MBP last night at around 35% battery and went to sleep. 8 hours later, I opened it up and it was at 6%.

    What could be causing the battery drain while it's closed? It should be asleep entirely?

    good Q, I have battery drain as well with lid closed and, presumably, the Mac is asleep. In energy saver pref's, I have checked put hard disks to sleep and do NOT have power nap enabled. I'm not getting drained as bad as you are though. Maybe 3-5%, still more than it should be.

    Another place to look may be the Power Nap function?
