Help! I'm on my second Model S. Best car ever, will never go back. I have a totally non-tech brother who just bought a Model 3LR. He tells me the car was charged up to 90% and left the car unplugged for 5 days, at which time the car showed 17% charge. He is having difficulty getting anyone to help him (end of quarter craziness, I assume). I have never had any kind of problem with the S, leaving it unplugged sometimes for weeks, traveling. Typically, when left unplugged, my S consumes 2-3 miles of range per day. I don't know if there is anything different, in this regard, with the 3. Is there something he is doing, or not doing, for this to happen? TIA
