EOS R6 depletes battery when turned off

[QuietNoise]

Hi,

I'm fighting with problem for weeks now. The camera depletes the fully charged battery completely after few days even when it's completely turned off during that time (the power dial on camera is in OFF position).

I went through many forums without clear solution for this model.

So, far I have camera in Airplane Mode on (thus WiFi and Bluetooth are off) and with GPS disabled. This happens to every battery I tried and those same batteries can sit in other canon DSLR cameras for weeks or months and still maintain their charge.

Is there anything else I can do make the EOS R6 stop battery draining when turned off (other that taking the battery out after every shoot)?

Given that you have isolated the issue to the lens configuration, and you say you are using a Viltrox adapter for your EF lens, it would be worth seeing if the adapter may be the issue, as it is not a Canon device.  See if you can find a Canon adapter and try that.

I have the same issue with my R5 and I have the Canon Ring Adapter. Someone else has the same issue on facebook on the R5 forums. I've been having to remove my batteries from the camera grip to avoid this drain.

I've also been able to confirm that my RF Lenses don't drain the battery at all it's only when using the adapter. Doesn't seem to matter if it's the Canon Adapter or a 3rd party adapter.

Correction on the Canon Ring Adapter "parasitic electrical draw", As an electrician who specializes in mobile installation used to recharge drones for the movie industry, the draw isn't from the ring adapter but from the camera trying to reestablish communication with the lens, flash or the camera wifi-bluetooth if you include the EL1 or EL5 flash, same circumstances, Mirrorless R7 attached to the EL5 flash does the same thing. Spoke with Canon and confirmed the findings. When the Camera isn't being used, the same with the flash - both batteries have to be removed and marked or numbered to return it once again to be reused until it fully drains batteries. The new "R" series mirrorless cameras do this, it is called "parasitic voltage drop" in circuits because electronic cameras are "electronic" it consume batteries! Best advice: When not in use "Remove", "Remove" rechargeable batteries to retain the longevity of the battery, hope this helps everyone...

I use Canon's adapter and Canon RF lens with R6M2.

But I have the same issue of battery draining.

I will look into this issue and update here if I found solution.

I just discovered that I have the same problem, but mine is happening much faster. I put a freshly charged battery into my R6 in the late afternoon. When I started my shoot that evening the battery was already dead!  Fortunately I had some spares so I was OK.

After replacing the battery I notice that even after the camera was turned off, I kept hearing/feeling the camera doing something internally. Sometimes audibly, other times I could feel something happening inside the camera but could not hear anything.  I ended up opening the battery door when not actively using the camera and that seemed to help.  But the problem is so new I have not really had time to diagnose exactly what is happening.

I use a Canon lens adapter so Vitrox is not the issue.  The only thing that I have done differently recently is that I used an aftermarket shutter release cable for a couple of Santa shoots.  But the cable was only in the camera during those shoots, and I did not notice any battery charge loss in the 5 days between those sessions.

Currently have removed the lens adapter and leaving camera turned off to see what happens.

Any ideas will be gratefuly accepted!
