Well here is the usual battery degradation topic.
To start with, I have a 05/2019 LR Model 3.
I have been tracking the data since pretty much the beginning, first with TeslaFi then with an in house solution Teslamate.
I am aware that the BMS can underestimate the actually max battery charge and the the BMS does a pretty good job at handling the battery.
I have read enough out there to understand that there is no magical remedy to bring the capacity back to max but i am getting to a point where i am worried.
I usually drive with % and not mileage. I use the data from Teslamate to give me an idea on "how much" i can drive with a full tank.
My driving habit are a bit all over due to covid and based on tesla recommendation, i was charging and toping off the battery on a daily basis up to 90%.
I recently changed to 70% just to see,
The reason for my concern is that there has been a constant degradation on max performance pretty much since March 2021.
It came back up a bit in june but then have been decreasing constantly up to now having only 268miles. This means that i am currently at 86% capacity after 30k miles.
this chart shows the charging habits. I've never really charged to 100 not been below 10%.
I also like this one to see if software could be a reason for decreased charge
I am really just looking at either
1. this is common and should not be worried much about it?
2. things to possibly to do (i keep reading battery calibration is useless)
3. what other people have experienced when taking the car to tesla and asked for a battery checkup.
This is what tesla told me recently
I agree that driving with % on is better. But i still need to get an idea whether i can drive about 300miles on a full charge or only 200. that makes a huge difference in planning when doing long trips.
My concern really is that based on what i have found out there battery degradation is expected but should stabilize, but i dont think mine is stabilizing.
Anyways thank you for those who will answer and sorry to annoy the typical user that will answer "do you own research" (which i've done)

Concern: Customer states: Please perform battery health check, wants to check if degradation was
normal
I feel this is more an "not at fault" answer just so they dont get bombarded with requests and what not.Technician reviewed vehicle log data and performed diagnostic of high voltage battery and related
components. No hardware faults or abnormal alerts present. Technician found when the battery is
consistently kept charged within a narrow window that estimation becomes less accurate and tends
to underestimate the true capacity of the battery. The result is an incorrect reduction in the displayed
range estimate. This does not affect the true range of the vehicle, as the true range is based on
physical measurements and not software estimates. Using the HV battery in a narrow range is best
for conservation over time of the capacity, even though it can lead to underestimated calculated
amp-hour capacity (CAC). We recognize the inconvenience and negative user experience
associated with this incorrect and reduced range estimate, and are constantly developing more
accurate estimation algorithms to improve experience overtime. We recommend switching range
display from miles or kilometers to percent (%). This setting, coupled with trip planning when needed,
will mitigate this inconvenient issue. Customers who have made that switch have reported better
overall ownership experience
