I did do a search, but didn't find anything on the first page of search results. What happens is this: I use the MB from the couch, plugged in, battery fine, for a few days. Due to security issues where I live, I shut her down and hide her. Sometimes it's a couple of days before I feel like surfing from the couch again, as I have the desktop to work from. Most of the time, I plug her back in, fire her up, and have a depleted battery! Sure, it's only about 30 mins depleted, but still? All updates are installed, and I've let her run down at least a couple of times to recalibrate the battery. I do get good mileage when I don't have her plugged in, but I find it strange that I shut her down fully charged, and when I fire her up again the battery is slightly depleted. And no, she's not sleeping when I shut her down. The Magsafe is fine. It glows orange when she's been plugged in after a couple of days of shutdown, but does glow green when the battery is supposedly fully charged.
