Is there something wrong with my battery?

I have midrange model 3 which I took possesion of in early February. I now have about 4000 miles on it. I have the StatsApp which shows a declining linear fit on my battery health (see photo). Is this a defective battery?

No --recent recalibrations have screwed up this kind of calculation. A promised fix has been made by Tesla in a forthcoming software update.

Thanks. Do you have any reference to this?

My total battery capacity estimate from TeslaFi take a clear step down with 19.5.15 in mid-March. It looks similar to your step-down at 3400 mi. This was widely reported and discussed at the time in the forums but I don't remember a specific thread to point you to.
