I have had the M9 for about a month now. It takes great pictures. However on at least 4 occasions I turned on the Leica (it had been off) and the low battery sign comes up. I had used the camera the day before, the battery was 80%, I took about 10 pictures, and it was 75% full. It had been in the off position for the last 24 hours. This is now the 4th time it has happened and is VERY frustrating. I know the camera was OFF because I have paid attention to it. Why would a battery drain from 75% full to empty in 24 hours while OFF? I am VERY VERY frustrated. Anyone else has this experience? Any suggestions? My previous Nikon kept a full battery for months even after taking 100s of photos.
