I have a reply regarding my loss of charge and key proximity.
Sadly no real answer to my question regarding battery heating in the pre-condition cycle, Some clarity on key proximity.....
"The preconditioning would affect the battery as power is needed to heat the interior unless the car is plugged in to charge. Keeping the key close to the car overnight would not cause this loss of charge - the technology used in the key stops producing a signal after 30 seconds of being stationary, this means that the car and key are not 'talking'. "
