    I picked up my Model 3 last Saturday, but this vampire drain really makes me go crazy.
    After driving home, it idled for 2 days, I noticed the mileage dropped from 215 mi to 185 mi in two days. that's average 15 miles per day, I never saw this much vampire drain in my Model S, then I sign-up TeslaFi for detail monitoring, after 3 days, the vampire drain rate stays the same, here is one day excerpt from TeslaFi:

    It loss 3.07 kWh per 20 hours equal to 14 miles.

    I tried almost everything, turn off walk by unlock, turn off bluetooth on Phone, using Key card exclusively, no result.It seems like this car never sleeps.

    For comparison, here is my Model S with Internet Always-on On vampire drain:

    Idles for 24 hours, It lost 1.26 kWh per day

    And here is my Model S with Internet Always-on Off vampire drain:

    Sleep 22 hours and idles 2 hours, total 0.22 kWh per day

    Does anyone experience the same with their Model 3?

    That sounds abnormal. The vampire drain on my 3 has been at most 1-2 miles a day. It was much better than my early S build (5xxx VIN), which lost about 7-9 miles a day.

    Your vampire drain on the S looks way to low. My 2017 always on loses about 1 (~0.3kwh) mile an hour. My 2014 that isn't set to always on loses about half that.

    Does the Model 3 have "smart preconditioning" like the Model S? If so, is it turned on? I have heard of vampire drain issues when smart preconditioning is used on the Model S.

    Sounds abnormal. Maybe try full shutdown in case some process is preventing car from sleeping.

    My 3 loses 1-2 miles a day... So improved from the S. OP has an issue that needs to be looked at

    Thanks for the info, may I ask how to do full shutdown? I only knew push both wheel knob to reboot the information system.

    I agree. My MX loses about 0.2 kwh per hour when idling.
    It is strange that the car never sleeps though. Perhaps teslafi isn't playing nice with it?

    I think you hold down the brakes and both buttons for over 45 seconds for a 'full reboot'

    Personally, I'd can Tesla amd have them interrogate the vehicle remotely as a first step.. It's a new car

    On my MS, losses are ~150 W (in "always connected" mode), which is indeed 0.150kW*24h/day = 3.6 kWh/day. Same range as your M3.

    Thank you! I did a reboot in your instructions, I'll wait and see.

    But I see there might be a problem on `power off` options.

    If I recall correctly, on Model S, when I clicked the `power off` button, the car should goes to shutdown.
    But on Model 3, it turns off the screen, then after about 5 seconds, screen turn on back to normal. seems like there is something going on with the system, it stays on forever.

    There's a power off button on the MS? Why would you use it? Did you use it to get the "way Low" idling?

    No, I only played with that function once or twice, my setup for Model S:

    Energy Saving: On
    Internet Always-on: Off
    Other minor setup:
    smart preconditioning: Off
    auto-prevent overheating: Off
    auto present handle: On
    Long Range mode : Off
    * TeslaFi Sleep Mode: On
    And the result is consistent, 0.2 - 0.4 kWh per day if no usage. 0.5-1 kWh if driving (some energy goes to 12V battery charging I assume)

    I was thinking that Teslafi might have an issue with the M3. Not the MS.

    Wow, I've never seen vampire drain as high as you are all reporting! At most, it's 2 miles a day, usually less. Of course, I have no Teslafi, "always connected off", etc.

    I've seen fairly high vampire drain as well, perhaps 5-10 miles per day lost. I've wondered if it was actually losing energy from the battery OR if perhaps the car was updating it's mileage estimate based on recent economy (wh/mi) data.

    That is the power off I was mentioning. Maybe it is not working correctly for the 3. Would have to have others confirm.

    This is unusual. I lose maybe 1-2 miles a day. The only time I saw anything like this was when I had failed to fully shut the driver door (easy to do on this car).
