Howdy,
Anyone have any idea what would make a Canon 1DX2 body drain the battery overnight while in the off position?
I welcome and ideas on whether anyone else has this problem, or if there is a setting I am not thinking of or if there is possibly a defect in my camera.

If i leave the batteries out once full charged - all 3 batteries (all genuine canon) work for a full normal shoot usage, so its not a capacity problem.
This is only a new problem that appears to have occurred now, this particular body and even my older 1D/5d series cameras maintained their batteries for months when left in the bodies.

I do have the GPS & Auto time update disabled since I know that would contribute.
I have flashed/updated firmware, reset camera back too default, and the problem still occurred.
