I'm honestly not sure what the problem is, or even if there is a problem. But I do know the solution: don't leave the battery door open.

snoke said:Ian_of_glos said:A couple of questions:
1) what happens if you do not leave the battery door open. Does the battery run down at the same rate?
2) Do you have GPS enabled and if so, which mode is it set to - mode 1 or mode 2?
1. No
2. No.

How long do you normally leave it for?
snoke said:Problem happen when you rush to put battery in camera and not close door. Dinner get cold or late to work and rush battery. Then forget until photo time. Then battery flat.

If I leave the door open will the battery discharge.
If it does this would be really stupid of car manufacturers and I'm going to complain.

Steps.
1. Remove battery
2. Insert battery, do not close door.
Camera think battery is not battery?
Door close, battery inside, open door and battery inside, not problem. Test this.

Charge battery, put in camera at night.
Morning, get camera, battery flat.
What wrong?
Battery door not closed!
Don't understand. Battery door open make flat battery?
Why camera use battery if battery door open?
Happen you too?
All camera or only 5D Mark IV?
Me dumb or Canon dumb?
Ian_of_glos said:The manual says:
2) Insert the battery:
* insert the end with the electrical contacts
* insert the battery until it locks in place
3) Close the cover
* Press the cover until it snaps shut
I think it would be wise to follow these instructions in future.

I loaded the battery into the camera but left the door open. Sure enough the battery is now being depleted very quickly - it has lost 5% of its charge in under 2 hours. So this confirms what you are saying.
