As most of us have experienced, phantom drain is real but can be controlled. My 2018 Model 3 SR+ (now totaled by a friend) lost about 1% each day while parked. My brand new 2021 Model 3 LR AWD keeps surprising me - it barely loses anything each day (knock on wood!)! As with my previous Model 3, I turn off Sentry and Wifi when I remember but this new car stayed at 82% for 2-3 days while parked in the cold. Bigger battery on a LR - possible reason? Better batteries? Whatever the reason, I hope it stays this way. TG
