I think this thread has derailed massively after the content wk057 had shared on battery gate. IMHO that concluded 737 pages of ranting against.

The issue has not been resolved for many capped owners. And, the class action lawsuit is still in progress.

I'm not the one so emotionally involved that I make up unlikely scenarios to support my feelings. I'm going by data as always. Tesla is claiming they have evidence of specific theft of documents, including admissions of employees doing so. Thousands of employees have left Tesla over the years, they are only suing a specific few with specific claims. Maybe read the suit if you actually care about the truth.
Tesla-Rivian lawsuit heats up as Judge denies misappropriation request
Tesla’s lawsuit against Rivian that claims the latter company attempted to steal trade secrets is heating up after Judge William Monahan threw out Rivian’s misappropriation of trade secrets claim. The Santa Clara, California Superior Court Judge also declined to dismiss claims that Tesla...

I'm sure that this will come of no surprise to anyone... Update on the class actions: CAND-ECF-Confirm Request
At least they got the year correct this time.

I don't use TeslaFi so not familiar with its inner workings. I don't understand what the 'battery degradation' graph you posted above actually shows. I don't see that improved readings show reversal of degradation, so on that basis neither does the graph show 'degradation'.
Does it show actual range based on miles driven which would possibly then change range estimate based on factors like temperature, driving style, tire size / condition, etc etc? Imo it must include some factors like these in order for the Estimated 100% range to drop then increase so much.
If you do a long hypermiling drive say from 100% down to 15% that would evidence the actual range as higher than normal, would TeslaFi show a step change in its range estimate?

I don't know everything about Teslafi either. The battery degradation (beta) display clearly shows an upward trend for me since June when I had an update.
The RR shown in the graph is based on the EPA consumption constant. There is a range remaining number which seems to be dependent on the last drive.
SMT confirms this upward trend as it reports actual capacity as well as RR.
Quite happy to have less than 5% actual degradation (77 out of 80.7 KwH) and 265+ RM after 40k miles and nearly 6 years
I don't hypermile, but I see no evidence that going lower than 30, or above 70, SoC, has any effect on BMS calibration or equilization of cells.
Going with traffic and minimal regen has me at 277wh/mi YTD.
Now, it is entirely plausible this gradual increase in range, if caused by Tesla, is not driven but a holistic desire to do the right thing, but rather to make them look good for the lawsuit.
I think we are all intelligent enough to know that any documents revealing Tesla's internal processes are worthless!

This is simple observation on my MS85D. Purchased as a CPO on 3/20/19. Published range 270 miles, 100% charge at purchase range 262 miles. 100% charge 4/2/2021 232 miles. When at an SC to charge from 20% to 80% the initial estimated time 35 minutes, actual time 60 to 65 minutes with preconditioning. I recently made the same trip in the Tesla and my ICE vehicle from Ouray, CO to my home in Arvada, CO of 302 miles. Remember that I am driving in mountainous terrain in the winter, using range mode, seat heater on low and heat at 68deg fan speed of 5. The ICE trip with stops was 6 hours, the Tesla took 8.5 hours with 2 stops to charge in Montrose and Salida and arrived home with 40 miles of range. I have been following the Class Action Lawsuit in hopes that the batteries will be replaced and the charge rates will be restored back to a rate that makes this vehicle usable for longer road trips.
Coincidentally, I just charged from 20 to 80% a few nights ago at the new 250KW supercharger in Merced and it also took 65 minutes. It started out with the estimate at 40 minutes which is what it would have taken on v8.1.

Just want to update on the De-Capping of my MS90D and MX75D Supercharging speeds. De-Capped speeds had reached about 124-ish kW on V2 & V3 superchargers. Temps are warming, and since getting my MS back from the body shop after the hit&run, I've put about 4,000 miles on it.
Supercharging speeds have now decreased again, still better than during the caps. Now my Max, regardless of battery temp or SOC, V2 or V3 superchargers, is 112kW on both vehicles. Still MUCH MUCH better than the 94kW cap before. My MS has not charged this fast in almost 5 years! (2nd month of ownership is when my V1 90kWh battery was limited to 94kW charge rate). Model S is at about 105,000 miles now, MX is at abut 95,000 miles.
My MX75D Was at about 137kW charge rate last year before it hit the 10 megawatt DC fast charge threshold and was capped to 94kW.

Same here. I have DEFINITELY done way more than the 30 cycles, and gotten SQUAT back

For those that are not seeing the increase in range, perhaps there is a new 90KwH pack in your future...

I wish that were true, but given the way Tesla has been treating us, I won't hold my breath.

In fact I am quite sure that it will 'magically' need to be replaced right after the warrantee expires.
battery warranty is coming up in Dec this year (original build date Dec 2013). bumper to bumper warranty is about to expire in two months. I guess I better figure out if this car is worth keeping or worth selling for the $25k the internet seems to think 2013's are worth. Personally I'd rather not go through the hassle of looking for a new car, but, I don't know how reliable long term this one will be. Getting an extended warranty might not make sense if the battery warranty is going to run out just a few months later. thoughts?

Depends how much you think your car is worth. Battery replacement is what.... 12k usd for the model S and with another 2500 usd charger upgrade and another 2500 usd for an mcu upgrade may give you essentially a new car if you dont need fancy new tech features?
Maybe watch bjorn nylands millenium falcon videos re: restoration and maintainance work needed on a high milage S?
If you have a P85+ or a signature S I think its worth keeping imho.
