16700 miles after 2.5yrs. HV battery is good. No other issues, but may change 12V prophylactically.
The Stats estimated range trend line is about to touch 310miles. Never been that high before. Zoomed in, it looks like 309.8miles. Definitely a unicorn, since I got it home delivered with Zero SOC.

I swear you must have started with an 81kWh capacity battery, haha. Even if you did, you'd have lost less than 4% capacity, which would be pretty darn good still.
its always frustrating to see how some people have no degeneration.
If it makes you feel better, he probably has had a few % capacity loss, but it's just not visible yet in the rated miles. No way to easily tell without SMT or extremely careful trip metering, when the car was brand new.
Seems like the 2017/2018 Model 3s for some reason have minimal degradation.
That's definitely not true. I know plenty of people in this date range with about 10% capacity loss.
My car:
No mechanical issues.
25k miles, November 2018, 10% capacity loss (~286 miles down from the original 318 (minimum) miles (which looks like 310, the way Tesla hides the initial capacity loss)). Realistically, I might have started with 78.5-79kWh of energy, and now I'm at 70kWh. (So could be as much as 11-12% loss.) I did not ever hook up SMT when it was new, so there's no way to know for sure exactly where it started, but I did not lose rated capacity for a while so I likely was considerably above 78kWh when new.
Mostly home charging, about 5-6 road trips with Supercharging (about 7.5k miles worth).
I suspect that there are 1) battery packs that lose capacity more slowly than others and 2) battery packs that start at higher capacity than others and thus can degrade more before capacity loss shows.
Remember for 2018-2020 vehicles, capacity has to drop below about ~77.7kWh before any loss shows. Before then, it is hidden through more energetic rated miles. (At least this is what the current evidence shows, and informs my current understanding.)
