I have a j1779 charger (240v, 30A) and I keep my Model 3 plugged in overnight with charging scheduled to start at 11pm every night. My understanding is that the car will not pull power from the battery if it's plugged in, is that correct? According to TeslaFi, last night: - Charging finished (limit set to 70%) at 12:21 am - Idle between 12:21am and 2:25am and LOST 0.85 miles - Sleep between 2:25am and 5:27am, NO range lost - Idle between 5:27am and 6:32am (when I went to work), LOST 0.85 miles Saturday night: - Idle between 2:04am and 6:00am, LOST 4.22 miles The car doesn't seem to use any power when sleeping, but loses almost 1 mph when idle, even when plugged in. I've only had the car for two weeks so I'm not sure whether it's related to an update. I've been updated once, from 24.11 to 28.2 but I've seen this both before and after the update.
