That version is in QA, not released to general public yet.
Thanks for that. Since there's no 'off' switch it is not up to me... I do live at 9,000 ft and it's been cold for the past week. That may have something to do with it.
Good idea - I'll do that and post what I hear back.
If an EV sits in the cold it will lose range from loss of battery capacity not from any vampire drains. I got to work with 50 miles left on the Tesla, it was in the 20's. When I came out 10 hours later, the car had 8 miles of range (not enough to get to the Tesla charger). New EA charger nearby and Chademo adapter saved me. Cold will reduce the range a lot. I'd guess that is what you are seeing.
If you mean the Tesla Model 3, a lot. I see a 30-40% range reduction in cold weather, under 40F. And letting it sit in cold, as noted above, it will lose a lot from warm battery to cold which seemed to describe the range loss here, range lost after warm car parked in cold climate.
Battery does not lose energy in the cold. You lose the usable energy but get it back when the battery warms up from driving. I’m in Alaska and have more time of the year below freezing then above, and have 8 winters with a Tesla up here.
Cold in itself does not reduce range that is until it gets below about -10 or -20F. But at those temps there are many variables so hard to say.
There is times a leave work when it is below 0. Drive 7-10 miles and gain %. On the Tesla it shows a blue bar on the battery to approximate how much % is currently unavailable but will be when the battery warms from driving.
This is normal. Tesla also loses about this much. At least mine does.
My 2014 model S and 2018 Model 3 didn’t lose anything meaningful sitting. I don’t have sentry mode, cabin overheat, or any 3rd party apps. I’ve had the model 3 sit unplugged for up to 12 days and lost at most 3%. The key is turn off sentry (or the Rivian yeti equivalent) turn off overheat, and do not check (and wake it up) from the app.
It’s not sitting as such but going from a 75F battery to a 20F battery, you’ll see significant drop in range. Sounds like what happened in the OP’s case.
When I leave my heated garage my battery is 60F and arrive at work and it could be -25F. I still don’t lose any % or miles. I can have a 40-50 degree temperate swing in a day regularly still don’t see energy lost.
What's the battery temp when you arrive at work? (I assume the -25F is outside)
Unless you've left the heat on, if the battery goes from 60F to -25F, you will see a big drop in rated range. You are not "losing energy" just the batteries ability to deliver the energy due effect of cold in Li-on.
