Switch to % and not worry about it until it gets closer to 30% degradation. I’m fact, that’s what I did; switch to % right off the lot so I don’t stress out about degradation.

Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

I would ask Tesla service about it, and go from there. However, this is really about what you want. If you're not happy with the car, then you may well be best to sell it and get something that you'll like better. I hear resale prices are good right now.
(moderator note)
This was merged into the "range" thread, because the post / content is "I am selling my car because of battery degradation (and high used car values right now)".
Hard driving vill still not degrade nearly as hard as leaving the car with high SOC.
If I would sue Tesla for anything it would actually be Pirelli for the tyres getting worn out after only one season. W8! That did happen to me before with the Audi biturbo.
The battery still shows good range despite a heavy right foot!
There might be a couple of issues with that.
When Tesla get you a new battery (if reaching below 70%), they give you a referbished bat that holds for 70%.
Then you have a standard range Tesla(if you started with a LR).
Also finding out after 6-7 years that the degradation more or less leveled out at 20%, making the LR a medium range Tesla.
The reason I wright my posts is to enlighten people about degradation and how it can be limited is due to the above points.
Anyone can ignore degradation, just follow Teslas simple rules. You willbe fine.
But that might put you in a position you dont like a few years from now, so the choise should be made early in the cars life.
Also, the research points to the fact that a lithium battery has a about proportinal degradation down to about 20% degradation, after this the degradation most likely is higher due to the lithiation.
When the 20% is reached it isnt that far to the 30% degradation level.

Actually I think it may be worse. 73.5. I'll get a picture posted. Appreciate all of the comments. This is all disappointing. Tesla says charge to 90. I largely keep it lower like 80 to 85. The car did spend some days outside in the summer. But to have an 8% loss this fast - normal or not - borders on fraud to me. I did absolutely nothing unreasonable and followed Teslas own rules. I expected some degradation but not this much. Hoping something is off.
Id say that while its possible that the BMS is a little off, ten months with 80-85% and and some 20C/68F probably already ”ate” about 5% from the capacity.
Calendar aging reduces with time so next ten months wont take the same bite.
Do you need those lost ”maybe” 5kWh? If not, look forward instead of getting stuck in whats already lost?
Its not to late to reduce the degradation and after some time be at least on average.
I think Teslas advice is ok. They give the owner the limits to stay within reasonable degradation and not cause a warranty problem after 7 years. This of course means not interrested as not following the change of the range each week.
Its nice for a not interrested owner to get a as big window as possible with as little ”musts” as possible.

it doesnt sound like the "lower max range" is impacting you in the slightest. You put a bunch of stuff on your car that has the potential to impact the actual range that you could go (not the number on the screen, the actual range), because you wanted to, and it doesnt sound like its impacted you at all.
So, in effect, you are getting upset about the "number on the screen" when it isnt impacting you, and in fact you decided to put stuff on your car that would lower your range yourself... because that didnt impact your usage of the car.
Sometimes people get really tied up in that number on the screen, and forget that, unless you are driving your car that range daily, it means very little in your actual usage of the car.
Yes all fair points. That said, if I have permanently lost 22 miles of range in 10 months and 6k miles, I think it's reasonable to be upset.
This is the nature of the todays battery technology. There are different battery types, all have their ups and downs.
For the longelivety, Panasonic NCA is good.
The battery will probably outlive the car anyway. If thats the case, there isn’t really anything to be upset about.
[Edit]
Heres the three main battery types of today:
I’d choose the NCA again for my M3P.
With a LFP you only have space for some 70-80% of the range anyway so you’d get a Standard Range wether you want or not. Which also will degrade.
So, my solution:
-You learn
-You accept
-You adept

So in other words, stress out early to maximize the life of the battery and potentially live years of worry-full ownership, or just relax and enjoy the car. I’ll just relax and enjoy the car.
Your own words “(if reaching below 70%);” emphasis on the “if.” Even at 20% degradation, I’m not going to stress. All your charts, graphs, and other data aren’t going to change my mind. But hey, preach on if it makes you feel better.
Dont missunderstand me. I do not say all should do everything to minimize degradation.So in other words, stress out early to maximize the life of the battery and potentially live years of worry-full ownership, or just relax and enjoy the car. I’ll just relax and enjoy the car.

I bring the facts about degradation, and then its a free choise to do whatever one like with that information. Maybe not even read about it at all.
Clerks is not okey with the degradation issue right now, and from where I’m standing you do not help much.
This thread is the: MASTER THREAD: Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health
So my posts about what to expect and how to minimize degradation is within the topic.
These post does not make me feel better or worse(except from maybe getting Clerks feeling better, which in turn probably would feel nice
)Theres no one trying to change your mind.
But hey, feel free to complain or whatever you do if it make you feel better.
Yeah well I guess I'll start leaving the car closer to 50 since it sits most days anyway. It sucks because a 90 percent charge brings a smile to my face performance wise. I do think Tesla should be required to disclose significantly more information to consumers on issues like degradation. I was also quite disappointed to learn how quickly performance drops off after 90 percent SOC. These are not 200 airpods with lithium batteries that are disposable. These are 55k cars. More disclosure is warranted.
I see no issue here. I asked for the information and appreciate the responses. I actually hoped to avoid this and am more in the club of set it to percentage and forget it. But the app now tells me both so I had no choice but to look.Dont missunderstand me. I do not say all should do everything to minimize degradation.

I have a new Tesla 3 SR+ ex China with the LFP battery. I am on my first 1,000 Kms. I am driving in metro Sydney.
My full battery mileage range has been at best 300Kms. I was expecting closer to 350-400 Kms.
Am I doing something wrong? Should I turn off services like Cabin Overheat protection, Sentry etc? Please advise.

There are 2 kinds of ranges:
1) Preset mathematical range displayed on your battery screen at 100% charge before you drive off. You should compare that range with same parameters such as the same ambient temperature (Hot summer has more range than subfreezing winter).
If your range was 300Km at 100% last year, and this year it shows 210 then it's a loss of 90Km or 30%.
2) Actual driving range. It's depending on your driving habit. If you used to be able to drive 300Km in summer, and by winter you can only get 250Km, then that might be because of the cold snowy windy winter. If you drive real fast at a race track and get only 150Km then that's because of your speed...
None of the above means you did anything wrong. It's just a matter of factors and you can adjust those factors to get what you want as needed. More speed then less range. More range then less speed...

out of interest:
there is someone who lives with me in tropical QLD who also has a model 3 performance who charges his car everyday to 90% (as opposed to 60% where mine sits) and he is sitting on even more than my 14% degradation - he only gets 405km rated range at 100%. so thats like... 22-23%?
The heat is probably not ideal for the batteries...
