    I parked my MS 100D AP 2.5 in my garage on Friday afternoon and it had 201 miles left on the battery. I didn't plug it in because I wanted to see how much loss I would have while on vacation. As on Wed evening (tonight) I have lost about 50 miles worth of charge in 5 days. Is this normal? Temps have been ranging from 60-85 degrees during the day. I had shut off the climate control on the vehicle when I left. I won't be back home for another four days.
    Thoughts anyone?

    Is energy saving mode on? Always connected mode on? Do you keep pinging the car via app to see charge level?

    I wouldn't be surprised if it lost 50 miles in a hot state (AZ/CA) but I think 50 miles of range loss in 5 days is too much if A/C hasn't been cycling on. Hmm. Do you know if temps in the garage go over 104F? Otherwise maybe there is a vampire drain -- check with SC if this is normal behavior.

    That is higher than I would expect, but not crazy if the car is not sleeping . Did you have power savings mode on? Avoid checking the car using the app too often as it prevents it from going to sleep mode and increases vampire drain.

    I get about 1% loss a day with power savings on, less than that If always connected is off. Maybe 2-3% lost each day with that off. The latter would about 8-10 miles a day.

    Note that newest model s with new mcu delivered after march 2018 or so may not have these settings as they are managed differently

    disabling always connected should help - a lot - and is probably the cause for much of the range loss per day

    I never turn on energy saving. then again I always plug my car in so :)

    its likely cabin overheat protection cycling everyday to keep the interior under 105.

    I don’t think the ac will be working too hard to keep it less than 105 if it is only 60-85 during the day. Maybe if it is under a fully sunny day, but he said it is in garage so that is very unlikely.

    Have a friend who lost 135 miles in 2 weeks (all the way down to 0) in the parking garage at Miami International while on vacation. Luckily the 12V was still alive and the doors and charging port still opened. Said the entire evolution to get the car down to the closed supercharger took 6 hours. 2017 85D.

    That's odd because mine doesn't lose anywhere near that amount. My car has been in service 8 weeks solid and has only lost 100 miles and has not been plugged in.

    Thanks for your wisdom. Maybe I'll just turn on energy saver. If I unclick always connected, will the vehicle still be able to receive updates from the mothership? I do connect with WiFi in my garage. Stupid question time, what is Vampire drain. I'd hate to get bit in the neck when I get in my car.

    Vampire drain is the lost energy due to the computers running when you're not in the vehicle.

    One more thing to consider...I believe I read somewhere here on the forum that cars with the new MCU don't have the Power Management options as apparently the car is supposed to handle this automatically.

    Yes it can still get wifi updates. It still connects, just not all the time. Another thing you will notice with always connected off is that if your car is asleep, it will take 30-60 sec or so to wake up if you try to connect it with the app before you can do anything.

    Ok, I've unchecked always connected and turned on energy saver but I still am having 8-9 miles a day drain. Called Tesla service and they say everything is ok on their end. I'm flying off on vacation for two weeks and the airport doesn't have any electrical connections (even 110) in the parking garage so I'm trying to figure out what to do. Charge up to 100% and hope for the best. I should be ok I think. Asked Tesla about shutting the car down but they said if I did that it shuts the alarm off.

    Suggestions??

    @Spidey423 That's still quite a lot (I have roughly 3mi/day loss). Do you have these fancy things like "Smart conditioning" or "Overheat protection" off?

    Do you have apps or services like Teslafi or Teslaspy pinging the car? Unless configured properly, those can prevent the car from sleeping.

    I do have Smart conditiong and Overheat protection off. I do subscribe to TeslaFi, so that could be the problem, but I have turned off always connected.

    There are specific settings in Tesla di that will allow car to sleep, make sure they are turned on. If you have Teslafi, use it to see if your car is sleeping or idling. If you don’t see sleep and only idle, then the sleep Co digs are wrong and will likely be the cause of the problem.

    Just looking back at teslafi for my last few airport stays where I didn't plug in with my MS 75D:

    9 days, went from 80% (197mi) to 63% (154mi): 4.8mi/day loss (70-80F temp, parked in partial shade)

    9 days, went from 78% (194mi) to 66% (162mi): 3.6mi/day loss (~50F-60F temp, parked in sun)

    10 days, went from 75% (187mi) to 50% (122mi): 6.5mi/day loss (30-40F, don't recall shade/sun)

    7.5days, went from 77% (193mi) to 67% (165mi): 3.7mi/day loss (30-40F, don't recall shade/sun)

    18 days, went from 76% (192mi) to 53% (122mi): 3.9mi/day (20-50F, parked in shade)

    14 days went from 68% (172mi) to 62% (157mi): 1.1mi/day (70-90F, parked in sun)

    I use teslafi, I have a dash cam that is always on, as well as a few other devices in the car drawing power. Always connected is unchecked, cabin overheat protection is on, smart preconditioning off.

    You answered your own question. I don’t understand people who have third party crap communicating with their car and then wonder why they have so much vampire drain.
