Mine went down with 12.1.2 also, and it was already very low to begin with. I'm now at an estimate 272 miles for a full charge. I'm cup-half-full-ing this, and figure that I'm already half way to triggering the 70% battery retention warranty.

My latest 80% charge was 210 miles. That suggests a 100% charge of 268 miles. Only 51 more to go until I trigger the 70% battery retention warranty. I'm 45% of the way there after less than 8000 miles.

I emailed support again, and this time they told me to power off the car, then charge it to 100%, and if that didn't work to schedule an appointment with service. Online support wouldn't answer if my car was covered by SB-18-16-010. I don't know that applies to cars losing range, or just to ones that never had full range in the first place. Doing as instructed did not bring back any range, so I've scheduled an appointment.

The odd thing is that the capacity loss from 308 to 274 occurred while the car was in service. I have no idea what they might have done to cause such a range loss. I even brought up the info screen in the car to make sure it still says "Long Range," which it does.

Other than the range loss, the car drives just fine.

My main concern is service will mostly shrug and say the car seems fine. At the current rate of loss, I'll be at 70% of capacity before 18,000 miles. My real concern is that my 100% range goes to about 225 miles, and then holds steady forever, so I can't force a warranty claim.

My battery took a hit with the firmware update I got in april (can’t remember exactly which version) and then took another hit after 12.16.2 that I got end of May. I typically charge to 80% and daily commute is ~50 miles. I did one calibration charge, 10%-100% and got 298. My drops seem pretty sudden after the firmware updates.

Mine also dropped with 2019.12.1 by about 10 miles range... have done the recommended 10%-100% “rebalance” 3 times without any change.

@JML yours sounds a lot like the car in the video I linked to in this post about my battery. The car in the video did have service “reset” the battery and got back to the 310 rated range.

I’m on the same boat! When new, I had about 307 miles on my P3D+, and at around 9500 miles, the battery was already down to 285 miles at 100%. I am up to about 13,000 miles, and still no change. Tesla tells me that it’s a known software issue and to keep waiting. I have done the cycling, rebalancing, many road trips where I charged you 100% and then down to very nearly 0 then back up to 100, resetting, etc. Nothing seems to help. I could have used the extra range during my cross country trips! TeslaFi report below. Any ideas? 09CD700E-60B5-47FC-8302-2A2D24A5051A.png

what FW were you on with that drop? 2019.12.x?

So first big drop from 306 to 300 I was on 2018.50.6, and the biggest drop, from 300 to 284 was 2019.12.1.2...am now on 2019.16.2....what are you thinking?

Edit: was looking through threads and found another of your posts where you suggest it’s FW related, and also 15-mile drop on 2019.12.1 that hasn’t come back yet...perhaps I’m on the same boat??

mine is similar. had a drop with 2019.8.2, then larger with 2019.12.1.1 that haven't recovered.
some of the early 2019.20.1 recipients are reporting an increase in rated range, so lets hope this is the one!

When I checked 2 months ago, I was seeing about 298 miles, not the 325 I should get on LR RWD.
Rain battery down to 4%, charged to 100%, got it up to 312.
Tesla SC told me to charge to 90% only. No partial charges below 90%. And that helped a tiny bit. After two weeks, it went up to 316.
Considering I have 11K miles, LR RWD and it will show 316 miles at 100%. Not bad for the miles, I suppose.


On my daily commute I use 8% each way to office. Trip is 23.5 miles.
Therefore 47 miles = 16%
A/C is always on and energy is usually about 235 on average, estimate. Suburbs, no major highways.

Doing the math, 16% x 6.3=100%.
So net miles would be 296. Not too bad.

But just finished a 1000 mile round trip.
At highway speeds when I see 280-310 kwh, I don't think I would get more than about 250 miles.
That's the real issue.

And to make that point, when I started my trip at 100%, the car wanted me to go to a SuperCharger 240 miles away.
It predicted arriving with 5% charge but I had to stay below 75MPH per warning on screen.
That's a bit close so I stopped at SuperCharger about 45 miles sooner.
So 250+ is about it at highway speeds.

So maybe the run down, charge to 100% and then sticking with only 90% helped.
But getting 300 or above regularly is like the ICE car MPG sticker. Under perfect, ideal conditions.

I am on 2013.16.2

Update!! Service Center performed a CAC reset to put me back at 310 (had lost 30 miles). Update here.
thats great news! i've been trying to get service/diags to fix for 6 MONTHS. most recently the remote diags person advised to run it down below 10% as much as possible for 30 days, and then recharge to 90% each time. yesterday i ran it down to 1% and charged to 100%, so definitely hit a full SOC swing. still tops out at 298 miles.

Since it has been exactly one year, I finally did something I wanted to do long ago when this thread first started: graphed battery range against firmware versions,. You can clearly see the big dip in 2018.36 and 39 when many of us were worried about issues, and rise back with new algorithms in 46 and 50. Then the bump in range (and power) with 2019.9.

I also highlighted the two times I charged to 100%, back when we discussed here and it DID help increase range that first time, but doesn't have any effect in more recent firmware.

It might be possible that the dip coincided with a drop in temperature, possible that old firmware was unhappy with anything under ~40F, especially if this is calculated after several days as seems to be true with the 100% calibration. Hopefully newer firmware is not as susceptible.

Also note this screen grab from Teslafi graphs over miles, not time/date.

I have less than 500km (310mi) on odometer full charged and only showing 460km (285mi) range. That's 7.2% lower on brand new car. Dropped it down to 20% and charged it to 90% only showing 415km (257mi) instead of 450km (280mi) again 7.5% Lower on car with less than 850ish km (528mi).

kWh consumed is more or less adding upto charged kWh. So there is definitely something very wrong with the battery.

Going to drive it down to 5% this time and charge to 100% and see. I have a scheduled appointment as well. This is not even close to expected.

This is normal on new Tesla’s (@TrevP has cited this in some of his videos). Put another 1-2k miles on it and your range should increase to the advertised levels. Congrats on the new Model 3!
