What's the normal battery drain for a 5D3 that's off?

I have the same problem, battery drains within 4 or 5 days without any use ... But this only happens if I charge the battery with the charger that came with 5D MK III which is meant for USA switches (I bought my 5D MK III from USA but I love in Middle East) ... but when I use the old 60D charger to charge the battery than there is no problem.

Well that's interesting.  Do the new ones trickle charge after the green light comes on?  Or maybe just stopping early?  Neuro, come edumacate us on the inner workings of the Canon chargers, past and present!

Hmm, that's interesting...

Per the measurements made by Garfield, you aren't really gaining anything by switching the camera off, rather than just letting it idle. In fact -- particularly if you have sensor cleaning set to engage each time you switch the camera on and off -- you may be discharging your battery more than you would by just letting the idle timer do its job after each 1 minute period of no activity.

I disabled auto sensor cleaning for that very reason.  When I was in Nepal for three weeks last year without ready access to power for recharging, I found that doing this and shutting the 5D3 off after shooting seemed better than letting it auto power-down.  Then again, perhaps shutting it off just prevented me from tinkering with it and needlessly engaging AF.  The CIPA standard (found at http://www.cipa.jp/english/hyoujunka/kikaku/pdf/DC-002_e.pdf) assumes one shot taken every 30 seconds, with a powerdown/powerup every 10 shots.  The 5D3 is CIPA-rated at 950 shots, so that equates to approximately eight hours of continuous use.  I was able to shoot a few hundred shots over a few days on one battery, so it doesn't seem so bad in comparison.  Interestingly, the CIPA standard doesn't prescribe a power off time, they just say it should be an amount of time which doesn't change measurement results.  So to the OP, it looks like the camera companies may measure off-mode battery drain, but only to determine at what point it isn't detrimental to the battery performance that they report.

Interesting indeed ... I am not sure if it has anything to do with it being an American power compatible charger or if it is the charger itself ... I'm waiting for a friend of mine to come back from his holidays to test if his 5D MK III charger (also bought from USA) does the same thing.

I charge my 5d3 batteries in my 7d charger...

... and I charge it with 60D charger now
