Do you just assume all EVs lose massive amounts of battery state of charge while unplugged? There's a reason Tesla vehicles lose battery while parked and unplugged; they have cameras and other computer systems continuing to run, sapping power. On the other hand, I have driven a 2018 Bolt EV for 4 years, 48k miles, and never once had an issue with the car being unplugged and returning to a car with less range than I left it.
