    I wonder if this will reset after a few charges to recalibrate the bms.

    It may. I've charged to full a few times for trips but I still get the full battery. I haven't charged to full since the extra capacity increase on the LR RWD yet, but my trip a couple months ago I charged to full 310 miles. Brought mine home mid August 2018.

    Mine dropped from 310 miles at 100% with about 1,800 miles on it to 300 miles with 7,600 miles on it. Purchased Oct 2018. My 90% went from 279 to 269-271. But the drop seemed to happen over two weeks, kinda sudden.

    Has this been a slow trend or all of sudden?

    I’m at around 7600 miles as well. My 90 percent recently, as I charged to that daily, shows around 269-272 as well. I wonder if it’s just with the recent firmware. I’m on 12.1.2.

    I’m not worried but just curious if others are experiencing it as well when charging to 100 when not done often.

    I start noticing it about 1.5 months ago when charging to 90. I use to get 278 then it dropped to low as 268 and now stable around 271. So I thought I tried charging to 100 percent for the first time ever to recalibrate.

    Does this range number take previous driving history and power usage into consideration?

    My car won't even charge to 100%. It will say "charging complete" at like 305 miles, but there's still some "room in the battery" on the app and on the in car screen. And TeslaFi doesn't count this is a 100% charge either. It's weird.

    My understanding that it didn't. But it could have changed and now bms does taking driving history and power usage into consideration. I just don't know. Anyone else might know?

    That is interesting, as i have read some only charge to about 99 percentage; or as it gets to the top, it slows the charge rate down. Perhaps mine really didn't get to 100% before the app reads charge complete. I don't have TeslaFi so I wouldn't know for sure if it is at 100%.

    On my first 100% charge about a year and 10k miles ago I had 316. Now it's 303. 90% used to be ~283 now it's 272.

    I keep hearing that to reset/recalibrate the battery mileage estimator you need to run the battery down to under ten percent then charge back up to 100% and do this a few times in a row. I've never let my battery get down to that low of a charge but I think I will try this and see what happens. I've only got about 9200 miles on my LR RWD model 3 that is over a year old (18 inch wheels, aftermarket rims, and running 12.2 - not that any of that should matter to the battery estimator). I doubt there should be any appreciable battery degradation at this point in the life of the car. Maybe there is something with the 12.2 update that is making a recalibrate necessary. Like others I'll report back my results.

    Now discharge it to 10%, then charge it back to 100%, so that we can know what the range really is. ;)

    Exactly the same here for 90%.
    I now get 272.27 miles, for my AWD.
    That’s after about 22,000 miles.

    That’s almost 98% SOC.
    Ya have to be happy with that. :)

    According to Tesla, it does. (I don't agree with this, but what can I do?)

    I've been experiencing this since November of last year, and each time I inquire/take it in/have them perform remote diagnostics, they say it takes into consideration driving history, power usage, outside temperature etc etc, and they aren't seeing anything wrong with my battery.

    Currently, my 90% is 267, and my 100% is 297. Has been this way since November. At the time, I was told that it was due to the way I was charging (every other day, and maybe only to 80%). The recommendation was to charge it daily to 90% and it would re-calibrate. I've been charging to 90% daily since December, have taken a few trips and been under 10% SOC, charged to 100% a handful of times, and I've seen absolutely no change.

    I understand that overall range is affected by many variables, but when the car is freshly charged, and is sitting still, the range should still be 310 at 100%, and once I start driving, THAT'S when the variables should impact range. I think there's a problem, and I think Tesla doesn't wants to admit it.

    FWIW, I'm on 12.1.2, and my lifetime Wh/mi is right around 320. Total mileage is 7,533 since 8/7/18.
