Just recently, my batteries are lasting just 2 or 3 days in camera at best. (Eos 70D)

Put a new 3rd party one in last night, and this morning it is already almost drained.

Question being - can a camera discharge batteries so fat, even when switched off, as to empty a battery, by way of a fault in the camera?

Hi Paul, it may help if you mention the model and if all batteries are third party or origina. Are you using a battery grip? I'm sure there will be someone who has encountered similar problems with your camera.
 
Hi Rob, I was editing my post when I got notification of a reply, so came to see what it was... :)

Camera is the Canon 70D.

Batteries are the original battery (approx 18 months old) as supplied in the box, plus 1 third party bought around 12 months ago.

Just added 2 new 3rd party ones yesterday, the first of which was near as dead as it could have been this morning, just overnight in the camera.

The power bar last night showed full. This morning, flashed red and almost done.

Another option maybe your charger is at fault ??? - especially if you just added 2 new 3rd party ones and they're also not lasting...

Do the batteries last outside of the camera ?
 
As per Rob's post above.....the power remains on the lens contacts even with the body switched off.

Does the 70d have wi-fi and/or gps? Make sure those are switched off if it does!
 
Does the Canon battery run down as fast or is it only the 3rd party ones? If it's the latter the answer is obvious.
 
I have a Venus macro lens attached (with a 1.4 Kenko TC) however, this stays on the camera, and has been on the camera for several weeks. It's a full manual lens.

I have had it since the end of February - but I think the battery drain has been just the last fortnight - which is about the length of time I have had the RF... Maybe it is the RF causing the problem? I will have to leave it off the next few nights, keep the Venus on, and then if I still get drain, swap out the Venus for my Canon 100 L IS lens and see if the same happens.

Sounds like a sensible way to test it. If the problem has started since the ring flash had been left on that would be a good place to start. Another way to test would be to have no lens or flash attached. Sounds like a bit of trial and error is needed.
