Putting the new MB to sleep overnight seems to drain the battery something like 15 to 20%. Anybody else getting this? should I just shut it down everytime?

Apply the Firmware update that Apple automatically piped through Software Update last week.

Typical in my experience with a MacBook Air; it will drain about 50% while sleeping over a weekend.

I have had basically all MPBs skipping every other model. I have always had the maximum RAM installed. This is the only source of power drain in a sleeping MPB. My MPBs have always lasted around 3 days or 33% loss of battery capacity per 24 hour period. For me the rate is the same before and after the EFI and SMC updates on my current late 2008 2.8 MBP.
