I never said it increased my enjoyment of the car. Same question you can ask LR/P drivers. They also only charge up to 80%.

I think this is the optimum interpretation of how ro best charge the vehicle - just got the M3 in Feb and love it

Set the charge limit to 100% and charge as much as you want. Make sure it goes to 100 at least once a week.
Solar using Charge HQ keeps my SOC at 50 to 80% mid-week. By Sunday night I'm back to 100%. So I comply with Tesla's once a week charge to 100%.
Keep SOC above 50% when parked as that is the minimum charge setpoint. Once a week charge to 100%. I don't think you need to over think it.

This varies slightly with temperature so don't worry if it doesn't always get the same number at 100% SOC.
The predicted range and SOC are essentially the same thing presented in different formats. Rated range is the BMSs calculated available (after buffer subtraction) amount of energy in the battery divided by rated wh/km. So you are not going to find anything useful doing this, if it thinks you have 60% SOC it's going to give the same rated range every time.
How do you charge to 100% without it automatically doing the BMS calibration? It gets to 99% then switches to calibrating, and depending mostly on how long since you last let it calibrate it says calibrating for 5-30mins then stops charging at 100%.
I have a 2023 M3. 8 months now about 4300miles. 1.6% degradation. I think this is mostly from calendar aging.
I use 8% Mon- Fri. About 5% on sat. 1-3% on sunday.
I have been only plugging in and charge once every week aprox…. When i plug in, i charge to 100%. By sunday i usually have about 50% left. Sometimes ill keep driving it till following Wednesday before charging so… i plug in/charge once every 7-10 days.
I am thinking of switching it up and charging it to 100% every OTHER week instead. So after week1 from 100% down to about 30%. Ill charge to 70%. Use it for another week Then when it get down to 30% again, ill charge it to 100%. So my average SOC is very low.
Any thoughts? Or should i just keep what i am doing - plug in/ charge once a week (7-10days)

If it were me I would do intermediate charges to 60% -80% (pick a number) then once a month to 100%
I do t like charging any Li-ion battery to 100% if I don't need to.
Sure, but if we all did what tesla recommends, a lot of these forums would not exist.
I see that everybody is confused about how to change LFP batteries.
I use home assistant for my home automation and I created one automation for my M3.
Once a week (on Friday) I set the limit to 100%.
When I unplug the car and the battery level is > 99%, I switch it back to 85%.
With this automation daily charging is 85%, and once a week 100%.
I think I will stay with this for a while, and if I find some more scientific explanation that I should do differently, I change it.
I drive about 100 miles a day.

Not sure where you got this from or how you arrived at this conclusion.
I'm not sure that your method is any more or less scientific than other people's charging regime so long as they follow manufacturer recommendations
I've read several articles about LFP batteries (in different content than Tesla cars), and all of them stand that for any other lithium battery, LFP doesn't like to be charged to 100%. But because of the lower/flat voltage, etc. it doesn't charm them as much as NCA or NCM. And I'm not talking about articles from automotive "experts" or influencers (they probably know as much about this as I do), but from battery industry insiders.
On the other hand, many people say that Tesla recommends charging them to 100% every time.
But Tesla didn't say that clearly either. They said to set a limit to 100% and charge 100% at least once a week (because of BMS).
But there is no clear statement on how to charge them and why (like they provided for NCA or NCM batteries).
So these are my thoughts.
But it's a long bow to say that everyone has got it wrong. There are lots of commentary here that says charging to 100% is for BMS purposes.
And the other point that yours is scientific is also a long bow. The only way that any of us can be scientific is to generate a hypothesis then test it. Do you have any actual evidence to say that your method of charging is better?. Did you test your method against another method to see which is better. Otherwise your method of charging is neither more or less scientific than any one else. Reading articles is one thing but the only way to be scientific is to test your method.
I didn't say that "everyone has got it wrong". I said, "everybody is confused". And that is a difference.
I think people are confused because Telsa didn't provide clear instructions.
There are two good articles I found that I can recommend:
Both have a lot of interesting information and studies. The first article compares LFP, NMC, and NCA and there are many charts.

My issue is still with the word "everyone" and that you want a "more scientific explanation". In this case confused is synonymous with wrong. But happy to use "confused".
I don't know how you arrived at "everyone" and how your method is any more scientific than anyone else.
Your post suggests that you are the only one who is not "confused". And also your quoting of articles does not make your method any more scientific or authoritative than anyone else.
Nothing wrong with sharing articles about battery charging and similar, but unless we are battery scientists like a Jeff Dahn , I don't think we can say everyone else but me is confused . Nor can we say that our individual method is better than anyone else's without actual experimental data on our battery method. Again quoting an article is not a sign of authority, rather it only gives some insight into the subject matter.

I think you pay too much attention to semantics in my posts. English is not my first language, so that may also be a reason. Saying "everyone" was more a figure of speech than thinking about 8 billion people in the world
Mainly I was thinking about myself - that I'm confused (and reading other posts I was impressed that I'm not the only one).Now when I see your point of view (how you read my post), I agree that I should start with "I see that everybody is confused about how to change LFP batteries, as I am.", because that was my intention to share...
I'm sorry if anyone was offended by my post and thought I wrote it to instruct group members (who certainly have much more experience with Tela than I do).
I think we can close this discussion because it doesn't add anything of value to the main topic.
