I am one of the people complaining about missing miles, ie, my Model 3 AWD came with 278 miles on a 90% charge but went way down this year to 260, apparently after a software update about April. Anyway, the weather turned much colder last week so I charged it up to 90% and went driving. Slowly, no rapid accelerations, no A/C or defroster and made sure the heater didn't come on.
Typically by the time the dash registered 40 miles remaining I would see the odometer show about 150 miles driven, so around 70 missing miles or about 25%. This time I got down to 40 miles remaining and I was only missing about 10 miles. I have not seen that good mileage since early in the year. I assume this means the A/C takes a LOT of power, like maybe 25%. I do know the heater also takes a bunch, but it's very hard to control without just turning the entire system off and cracking a window. I like many people would like to see a Heater on/off button next to the A/C.
So, for now I'm going to stop complaining, except that I never saw the 5% or 7.5& or whatever it was supposed to be increase with 2019.36.2. I think AWD didn't get it for some reason.
