It certainly is representative of my Tesla MY (loss 2-3% /day) until about 2 months before trade in. (Then vampire drain appears to have "stopped". My unfounded speculation at the time was that vampire drain was becoming a talking point on forums, and they figured out how to "fix it". But that's just speculation.)My personal experience with Model Y and reports on forums is that there is no significant vampire losses on Teslas anymore. Sure if using cabin protection in Las Vegas you might experience similar drain, but your Tesla is not representative of the Tesla fleet whatsoever. Every Rivian has this problem though.
A larger point, and one that I've made before is that we actually have no idea from these anecdotal reports how much drain there actually is (no disrespect to @zonehawk as I still appreciate seeing these reports, and his is one of the longest duration/controlled tests I've seen). But as whole:
- As a group, they are taken in different vehicles with different configs
- Different software settings on each vehicle
- As individuals and as a group - different temps between readings (ie take one reading when I get home and one the next morning, both the ambient and battery temps are different).
- Different use of app (quitting app? leaving it running but not checking in? checking in?)
Furthermore:
- How accurate is judging vampire loss on what the display says?
- What does the % battery remaining actually even mean and how is it calculated (nobody outside Rivian knows this) and is is calculated the same method as a Telsa? as Ford? is Ford simply programmed to display the last known range until driven? Hyundai? Do they all adjust as you drive?
- There are reports Ford does not change in cold temps. That can't be right?
- Why does my rivian percentage occasionally go UP while driving? Doesn't this speak to inaccuracy?
- Does a 3% decrease in percent equal a 3% loss of range?
My Tesla used to tell me I had 300 miles available, but would only reliably go 200. So...which is worse? Notorious inaccuracy? Maybe the Rivian % is a more accurate predictor. Maybe it's not. I can tell you from experience that the range is way more accurate.
I just think we need to take all anecdotal figures with a grain of salt.
And the one by the OP, with a grain of salt, is more promising than some others.
