Hi all,
Starting with software version 2019.32.2.1, I have started seeing a steady decline of maximum battery capacity. I started at 310 miles and currently am at 299 - which is about a 3.5% reduction with only 7800 miles on the car. I originally thought that it may have been related to weather, but despite the recent (and unusually) warm weather in the Bay Area, my LR AWD is still trending down.
I reached out to Tesla support who ran a battery diagnostic on my car and claimed no issues. I also asked them what my maximum range should be - 310 or the newer rating of 322; they confirmed I should be at 322 (I now have 2019.36.2.1) - so if we base that as the max, I've now lost 7.2%.
Tesla support also suggested I do 3 cycles of charging to 100% and discharging to 10% - compared to a coworker who's SR+ has a different issue (full charge says 250 miles, he will drive 100 and will have only 50-60 left) and was recommended to charge to 90% every night for 4 weeks. They claim that this may reset the range indicator and when I pressed about what if it does not, the response was "meh."
So I have the following questions:

So I have the following questions:
- Should I bother doing the 100% to 10% cycles?
- Any of you who has had their car go through previous winter (especially in the CA Bay Area), have you experienced the same issue where the range drops and then comes back up with the warmer weather?
- Has anyone with a LR AWD observed a 322 range on full (or thereabouts) charge with 2019.36.2.1?
