    I've been doing some searches but not found conclusive advice on what is best to do if the car is parked for a prolonged time where there is no charging available.

    Common suggestions include:

    Power Saving = ON
    Always connected = UNCHECKED
    Do not check the car using phone APP (because that will wake the car)

    Ones I'm not sure about:

    Put the car in Range Mode?

    Configure APPs

    e.g. TeslaFi has good Sleep control options
    I cannot find anything in TeslaLog that is likely to make it sleep
    If I close the Phone APPs is there anything in background that might still run?

    Further suggestions:

    Change password - so no APPs are able to connect

    Turn the car OFF when parking - would that make any difference?

    I have read that the longer the car is parked the more aggressively the energy-saving that is applied

    Smart Pre-Conditioning = OFF

    Make sure the tesla widget doesn't appear on your lock screen or notification center, because that will also wake the car.

    Cabin overheat protection = OFF

    I'd make sure any logging apps/services are disabled. Changing your Tesla password will do that for sure, but is a bit excessive.

    Check your power drain for a day in your garage with all your settings and see how it goes. You should be able to get down to less than 1 kWh/day lost.

    My first experience with Vampire loss aided by reading all these threads was very positive

    Model X 2016 5 days at Syracuse Airport covered parking outside temps avg 72-85F
    Energy Save mode ON
    Smart Preconditioning OFF
    Always Connected OFF
    Range mode ON

    I NEVER checked the car with any App

    Astonishingly the loss was 1 Mile total over the 5 full day

    I have experience here....

    I returned last week from a 17 day trip and our 2014 Model S ( pre-autopilot) used 1.2miles / day vampire drain while parked at Sky Harbor airport. We charged the car to nearly 100% at Casa Grande Supercharger on the way to the airport in anticipation of vampire losses.

    However, to minimize vampire losses I indeed had:

    Always Connected: OFF
    Range Mode: ON
    Smart Preconditioning: OFF
    Energy Save mode: ON
    I did leave Cabin Overheat Protection: ON- but I read that it only runs that feature for 24 hours. I'm not sure what it actually did

    I did not check the car remotely until the plane landed upon return from the trip. The car took about 45 seconds to respond when I logged in, and I was able to set the climate control to on so that when I arrived at the car the cabin was a comfortable 72 degrees. It was 104 outside when I got to Phoenix.

    I was very happy, I had expected it to use about 2.5 to 3 miles per day - and had planed to need a stop at the Casa Grande supercharger on the way home, I was able to skip that stop.
