5DIII battery drain overnight?

Twice now (in the 3wks I owned it) I had my 5DIII working fine with a reasonably charged battery one day, and the battery totally drained the next day to the point where the camera didn't turn on. In both cases putting in a fresh battery worked. I confirmed that the battery was discharged. This happened with two different batteries, both Canon.

I do have an Eye-Fi card in the camera, but it's almost always in disabled state.

I also often just leave the camera on when I stop using it. Auto-Shutoff is set to 1 min.

Anyone else see this? As a next experiment I'm going to take the Eye-Fi card out.
