Answering you
@jjrandorin but it is for
@CHB12312, I got the quotes in the wrong order…(I guess/know you know this
)
For the US M3P it is actually 55% or less (Panasonic NCA chemistry) to be sure to be below the sharp step thst reduces degradation.

In this test, they also found the reason for the step, the central graphite peak. It is positioned at 57% true SOC, wich is thexsame as 55% displsyed SOC in a Tesla LR/P (the buffer below 0% displayed offsets the reading).
To maximize power you would like to have high SOC, and a warm battery.
So to get all out of the car, 80% + would be needed.
It is recommended to charge late, just before leavijg on the drive. This makes the battery warmer (better power) and also reduces the time at high SOC.
You should not worry too much about degradation but it might be good to know that 80% and around (actually any number above 55-60%) will give about double calendar aging compared to low SOC.
The battery in the M3P is not the battery with the lowest degradation so be prepared to loose some, specially the first year. It is normal and a part of having an EV.
You will probably be told by a lot of people that 80% is the best SOC, but they have in that case gotten bitten by the common myth that
