Something interesting happened 2 weeks after getting my X 90D. For the first two weeks, my 90% was consistently a minimum of 236 to 238, with the most common value (per Teslalogs.com) of 237.
Suddenly, at the two week (1500 mile) mark, my 90% level dropped, and is now consistently a minimum of 230 and a maximum of 232, with the most common value 230.
What happened at that break point where I lost about 3% of rated capacity? Two things: for a trip, I charged for the first time to 100%, and during the trip I used a Supercharger (though only for 20 minutes) for the first time.
My question is whether this is a calibration issue (i.e. my early 90% figure was overstated because the battery had not been calibrated, but charging it to 100% for the first time forced recalibration) or whether the act of charging to 100% (I drove the trip almost immediately after hitting 100%) or supercharging for the first time might have done something to the capacity.
Thoughts?
