New 5D Mark IV.
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?

         /
        /    <- Door / Variant 1
_______/
       |
       |

    \
     \       <- Door / Variant 2
______\
       |
       |





The door position in variant 2 might trigger the switch which informs the camera that the battery compartment is closed. If that switch is a little bit wobbly it might trigger that switch again and again.
Closing the door activates the orange LED near the battery compartment (back side) which checks the storage card.
If the camera boots and checks the storage card this might be powerconsuming and draw the battery.

Just my 2ct.
Most used tools: EOS 200D + EF-S 60mm + 4.0 / 70-200 IS AND/OR EOS 5D i  + 4.0 70-200 IS + 2.8 100 Macro

This time I removed the battery before starting the test. At the start of the test my battery was at 72%
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.

One thing I noticed was that the access lamp flashes as soon as I close the battery compartment door. My guess is that there is a process running inside the camera to check whether the battery compartment door is closed and when it detects that the door has been closed it then tests the memory cards. This is probably what is consuming the power.
However, I have owned a Canon DLSR for 7 years and I have never encountered this problem. In order to perform the test I had to try quite hard to create the symptoms you describe.

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.

The 1D X doesn't have a battery door, but what would happen if I pushed the battery into the slot but then I urgently needed to clean my andirons and didn't twist the lock on the camera battery because that would take too long? 

Similarly, what would happen if I pushed the battery into the slot but then I had to pick up my suits from the dry cleaners and didn't twist the lock on the camera battery because that would take too long?

Or, what would happen if I pushed the battery into the slot but then I heard the toast pop up from the toaster and needed to put butter on it before it cooled off, so didn't twist the lock on the camera battery because that would take too long?

It may be difficult, but I'll try not to let these conundrums keep me awake at night.

I thank the last two posters for their enjoyable and dry humor.  Such humor adds much to the Canon Rumors experience.

In fairness to the OP, he did follow the instructions...they do not explicitly state that step 3 should follow step 2 without a significant temporal delay.  Similarly, one could follow the instructions on a shampoo bottleā€¦ Lather their hair during their morning shower, but wait until returning home at the end of the day to rinse out the shampoo.  :)

Yes. Follow instructions always good. But humans not perfect.

So that's what happened to Supreme Leader Snoke.
He must have left the door of the Starkiller Superweapon open and the battery went flat when he went to use it.
