Took delivery of my car almost exactly a year ago and had a Tesla Wall charger installed before I took delivery. Over the last six+ months it seems when I charge at home my range decreases, but if I travel and use superchargers my range is higher. Originally I was charging at 32 AMPS at home and recently changed it to 40 amps and the range seems to be dropping faster. Anyone experience anything like this? I've tried letting the SOC get down to 20%, usually charge somewhere between 80 & 90% and have rarely gone over 90%. Here's the TeslaFi batter report. My last two charges were at home and range dropped. I did a charge at a SuperCharger right before that when the range went up. Due to Covid is sitting quite a bit and only getting short local drives. Has anyone seen anything like this? Could I have power issues at my home causing the problem?
