I'm sure I'm not the only one who has noticed that Sony cameras tend to drain their batteries even when turned off. I have an A7 Classic, an RX10 and an RX100 V. This phenomenon is striking compared to any other digital camera that I have owned. Of course, like an idiot, I have only recently begun keeping my cameras in Airplane Mode. It remains to be seen just how much this will help. I'd be interested in some feedback on this subject - and any other ways to preserve battery life if I'm not using my cameras everyday. Is simply taking the battery out of the camera and resetting all my preferences every time I go out shooting the only real way to preserve battery life? All of my other cameras can go many months before installed batteries run down. With my Sonys, it's a matter of a few weeks.
