Canon 6D battery drain when off?

No
Twice now I've pulled out my gripped 6D to find the batteries are dead or very close to it (0% & 6% this time) when I'm sure they weren't when I put it away. Have never experienced this on my 5D3 which holds its charge well when off.

Has anyone else experienced this?
 
GPS on prior to switch off? Even when the camera is switched off it remains active and drains batteries.
 
Check when it is set to auto turn off. I too noticed it with my 6D compared to my 40D then realised it wasn't set to auto turn off at any time (unlike the 40D was).
 
GPS is disabled and both the camera and grip were turned off. It could be my imagination and they were indeed almost flat when I last used it but I don't think so - need to keep an eye on this next time I use it and record the levels when I switch it off.
 
Just realised you said when switched off...my bad! I havent noticed any drain when switched off, just when left on (and thinking it would switch itself off).
 
Charging both batteries now, will then leave it for a while and see if I'm imagining things - don't need to use it any time soon so good time to test.
 
I thought I had a problem with my 5d3 after it came back from Canon, but it was because the menu option to power off after a preset time was set to 'disabled'
 
No this is when it's properly off rather than auto power-off.

One interesting note regards the auto-timeoff which may catch people out - I have mine set to auto power-off after a few minutes to conserve battery, EXCEPT when using the custom modes. I have these set to not auto power-off at all, the reason being that, when the camera powers off, then you wake it again, it'll reset all settings to those stored in the custom option (unless you've set it to automatically save changes which I haven't). I use these custom options for things like silent shooting so I can quickly dial that up when needed at weddings and so forth but, if you select a custom option and then change things like aperture, shutter speed, ISO or whatever, if the camera powers off and you wake it, they'll all be back at what's stored in the custom setting and you may not realise that at first.

Just a little "gotcha" which might be useful to some people :)
 
check the wifi and gps are off rthey drain the batt even when it is off
 
Yeah both of those are disabled as I don't use them
 
Also be aware that a lens error can also drain the battery.....the power contacts for the lens drive motor are not disabled by the camera's main switch.

Is it the Canon grip or a third party grip?

Meike grips have been known to drain batteries when switched off, though I have no idea why?

No lens errors and it's a genuine BG-E13.
 
That's strange. I have the genuine grip for the 6d also and I've not had any unusual draining. Have you checked battery info in the camera, it will give you a basic health report on the batteries, though I think you'd have to remove the grip as it reads them individually?

I had this on my 50D. It stopped either after a firmware upgrade or I'd sent a lens in for repair.
 
Following up from this charged two batteries up fully on Monday night and inserted them into my Meike grip on my 6D. Just checked both and they are reading 99% in body. 1.1.6 firmware, gps enable on the Canon OS but using Magic Lantern (latest nightly) to disable it on power off which it then enables when powered on.

Sorry it's no help but from my testing and experience it's certainly not a trait of the body.
 
Maybe there's an issue with the Magic Lantern?
 
I've now charged both batteries to 100% and put the camera away, will check it again in a few days to a week and see what the levels are like :)
 
My 6D did this the other day. Wouldn't even turn on. Battery was drained fully and it was almost full when put away. Something was draining it so you ain't imagining things.

Next thing to try then is leave it with out lens, body only and test over a few days, then repeat with your normal lens you leave on, and with another lens.
 
Just fished it out a week later and the batteries are at 97% & 95%.

Guess it was just my imagination then, oh well sorry to waste everyone's time.
