Phantom drain, 2-3% per day?

I just check my TeslaFi records for the past 8 days...

Charged from 28% to 70% on 3/16/2020 @ 2:30pm
Added 3.06 kWh on 3/20/2020 @ 6:42pm
Added 0.21 kWh on 3/22/2020 @ 6:45pm
Added 3.32 kWh on 3/24/2020 @ 6:42am

So over a period of 7 days and 8 hrs we have seen a drain of 6.59 kWh, or 0.90 kWh per day.
 
I recorded my Phantom Drain a couple of time, just for shiits and giggles:

on 13.02.2020
Parked with 375km at 08:13, temperature 1c
Picked up the car at 17:55, battery was on 374km, temperature was 8c
(1 km lost during an entire workday)
Checked car with app: no

on 02.03.2020
Parked with 305km at 08:01, temperature 4c
Picked up the car at 18:50, battery was on 30374km, temperature was 6c
(2 km lost during an entire workday)
Checked car with app: twice, several hours apart.

So friggin cold both days and the MX had hardly lost anything (2km is way less than 1%). I'd say that's pretty darn good.

The car must be allowed to deep-sleep though. And Sentry was not used (i rarely do by the way).
 
Yes, the vampire inside is hungrier than most EVs. I am not aware of any that use more power passively.
I did my homework and expected it. To me, it's worth $10 a month in parasitic loss not having to drive to a gas station.

Mine started massively draining once I installed 2020.12. Seems there is a bug in the software keeping something from letting the car go to sleep. Apparently Tesla is aware according to another thread on here regarding the same issue.
I noticed the same thing after install and assumed it was software. Hopefully this 12.1 will fix it. Not many cars have it yet.
