Battery Vampire Drain Observation Data (sitting in cold temperatures)

[MyOtherTruck]

My CT will be resting in my snowy northeast driveway while I drive my other vehicles (with blizzaks). Curious, I am watching the battery drain over the course of about 10 days (in the event I have to leave it unplugged a while for the plow guy!). I check the app 1x a day to record battery level. I have sentry mode turned off (that'll be a future test). The truck is unplugged. The temps are freezing or below, but a couple days of warm up are coming next week. It has been snowy the last 5 days...

Day 1 277
Day 2 273
Day 3 270
Day 4 263
Day 5 266 (interesting it went up - maybe warmer out).

More data to come....

nice, thats really good for that kind of weather

Great test for all those out there who have to leave their Trucks outside. Better to do it under a controlled environment and know what to expect when and if it happens for real.

Great job with the test. I would have expected a steeper drop but this is good to know. Looking forward to you future test with sentry mode enabled.

My Cybertruck has lived outside since I picked it up in early April.

Not a problem.

It’s losing miles sitting there so it is a problem

I’m in western Pa and I leave mine out all the time. I have had battery drain as well as “stalled” charging due to cold, and it’s really not that cold!

Thanks for sharing this. That sounds like about 3% drop over 5 days. Not too bad for cold weather.

My CT is currently sitting unused in a 53 degree garage. It has dropped about 4% over 5 days, that's with me turning on sentry mode once per day to look around, then back off again.

Is your Wifi connected? I'm guessing it makes a difference, since the truck may be uploading/downloading data while sitting on a wifi connection.

The holiday update is supposed to improve CT battery drain when Sentry is on.

Didn’t see that listed

Checking on it once a day will wake it up and cause battery drain.

This is good info but makes me think there is something else going on with my truck. I loose about 4% - 6% (or more) per day in a heated garage (warm or cold out) without sentry or anything. It all started with an update back in the summer. I loose more energy to vampire drain than I do driving my truck during the week! This is starting to upset me as I keep thinking it's going to be fixed in the next update but not so far. Before the update I never even lost a whole 1%.

That has definitely happened to me a long time ago with my model 3 which was eventually fixed with a software update. It might be worth submitting a service request to run remote diagnostics and/or to see what they have to say. Report back!

Pardon if I've said this to you previously, but have you tried doing a double scroll wheel reset and a vehicle power off? Software may be stuck-ish. I had issues after a summer update and that fixed it (after three resets IIRC).

How has your drain been…how low and how long unconnected?
