Has anyone else had problems with their D4 battery going from nearly full, to zero, overnight? It's happened three times in the last six months. No pattern. The first time I thought it was my fault since it was in my bag and maybe the AF-On button was being held down and the camera was trying to focus all night long. But the other two times it was on a shelf and no possibility of any buttons being pressed. The power switch was on but that shouldn't do it. No wifi or gps or anything else funny.
