looks like you apply your low SOC theory to your cell phone battery as wellI forgot to attach a picture:
Teslalogger data on range vs ODO.
Rember that tge ODO reading should have very little to do with the degradation and displayed max range.
M3 RWD with the LFP batt.
The higher batch of ranges origin at ~ 438 km.
We can see that the loss is not too far from the other M3 batteries (LR) seen in lost percent.
Thos is calendar aging that we see.
