R5 battery issue: Draining while in camera (and camera is off).
1

One time a few weeks ago, I went to grab my R5, knowing I had charged the battery (as I always do after using it and put it in the camera). To my surprise, I turned it on and nothing happened. I put the R5's battery in the charger and it was completely dead. Huh, I thought, maybe I forgot? Charged it up and used the camera. I charged it again and made sure to triple check it was fully charged. I put the battery back in and a few days later went to use the R5 and the battery was 70% gone.

As an experiment, I charged the battery and left it out of the camera for a week and then inserted it, 100%.

Am I alone in this or has anyone else noticed the battery is draining while in the camera (and of course the camera is off)?
