A7Rm2 excessive battery drain on standby

For the last few weeks I notice an increasing tendency of my A7Rm2 to deplete the battery fast, even when the camera is switched off. This morning I put in a fully charged battery, showing 100 % in the finder and after a few hours the charge was down to 82 % while the camera had been switched off. Two weeks ago I tested my 2 older batteries (came with the camera 3.5 years ago) with a home-built discharge unit and they still had a capacity of 750 mAh, while 2 newer batteries show values around 1000 mAh. So all batteries seem to be OK, the older ones just showing 25 % less capacity.

Anybody know what might be causing this behavior?
