High Battery Vampire Drain

[Cybergirl]

I always had 2% drain on my 2018 Model X and left it plugged in at night. Then I started leaving our cars unplugged and it stoppped. It’s like the car cant go into proper deep sleep while it is plugged in

Interesting. I'll have to test that myself.

8% lost overnight in a climate controlled garage, all systems off and plugged in.
interestingly the climate in the truck was warmer than the garage temp, as if something was warming the inside.

Well, with all those computer systems consuming that much energy, it has to go somewhere.

I'm hearing that parasitic drain while plugged-in might be fixed in the next update

Would be awesome. Where did you hear that?

Sentry on or off?

sentry off

last night in 12 hours it lost 2%. Sitting outside, 50 degrees, no sentry, and no wifi, not plugged in. Seems high, my model y loses almost nothing over night.

Parked my CT at the airport for five days (In the 50s mostly) - no Sentry mode. Lost 4% in five days. It seems it loses more while connecting to Wifi at home, or while plugged in, or if your phone frequently connects.

Yup I can confirm that. Charge to 80% overnight. Ends up at 78% in the am so def a little drain while it’s still plugged in

Is everyone plugged in to a 110v outlet? Get a 240v nema 14-50 this issue should disappear.

No, plugged in to a Tesla Gen 3 50amp charger.

Same here. I think the battery needs to cycle down closer to zero a few times to calibrate that.

Seems much better after 2024.8.4

Left my model 3, model y and CT in garage 10 days ago and went for vacation. All had 80% charge and were unplugged. Y and 3 have 70% charge today and CT has 40%.

I remember in 2018 my model 3 had bad phantom loss too. It got better update after update.

Trucks drop about 5-6 kwh overnight 12 hours
Sentry mode drop about 12-18kwh overnight
Those numbers were consistent for both trucks
That is in climate controlled garages. The amount of power consumed currently is not green and needs to be fixed via software right away or we are going to lose the better for the environment argument against ICE trucks.
