The 2016 Tesla Model X consistently showed about seven fewer miles in range every morning than the night before.

    I know that Tesla WANTS the car to stay continuously powered, in order for all the GPS and Data gizmos to keep working, but I wonder if there is a way to do a "hard shutdown" on the Teslas. I know there has to be a way to isolate the battery packs for their service techs to work on it, but its essentially a giant rolling Android tablet. There must be a way, somewhere within the code, to get the vehicle to completely power off, then allow you to reboot it. This will end up being a desirable feature, I think, when the vehicles get older, and they start developing glitches that a reboot may solve without having to find a tech/mechanic to mess around with it.

    Well that's about what a "normal" car might do---a dead battery if it sits for 30 days.

    One would think that Tesla would have a separate small LiFe battery that keeps the sleep active functions going so as not to reduce the range from the motor batteries.

    @Mark Takahashi - I know early Model S's had some pretty big problems with accessory drain. Did you guys notice any issues with your S?

    Does the X show exact remaining battery capacity or just a range estimate? For example, on my Volt, the miles remaining is only an estimate and varies according to my driving/conditions. It may say 34 miles when I get to work then say 33 when I head home because the temp jumped 20 degrees. I can't see the exact capacity remaining.

    Have you thought about fully charging the X then parking it for 2-3 days to see how much range bleeds off? Perhaps measure it daily?
    Don't worry about what other people think. Drive what makes you happy.

    There are several power saving option modes in the Control screen. The best combination is to enable power-saver mode but keep the wireless communications active so you can still pre-cool (or heat) the car and monitor charging status. You might have power saving mode turned off which will use the most power while just sitting.
