I will have to park Joules for 10 days in a location that charging power is not available (Vacation on a no car island, must park car in ferry terminal lot). The parking lot is about 93 miles from the nearest Supercharger. I know she will not be dead, but depending on how low she is, I may have issues returning to the Supercharger. I have a P85, with AutoPilot and 6.1 (2.2.92). I will have the Power Management System's Energy Saver turned "On" without "Always Connected". I understand not to peek with my iPhone app to check. If I have missed any other bases to lower the Vampire losses, let me know. What I asking is what level of loss should I plan for? I have seen a video in which Bjorn Nyland left his car an Oslo winter for 27 days and had an average loss of 2.3 miles per day. But given the date of the video and that he is in Norway, I am certain Bjorn had different firmware. I called the local Service Center today and was told losses would exceed 5 miles per day and could be up to 7 assuming I did not peek with the iPhone app. My gut tells me Tesla would have data on this, but trying to get that data is a mystery. If anyone has experiential data on vampire losses, I would really like to get it.
