Recently received a 2022 MS LR and park in the driveway so keep sentry on always. I charge the car daily via a Tesla Wall Connecter starting at 9pm when rates are cheaper and then notice in the morning it is around 2% less than the target charge level. Is this normal as it is about 7 hours or so since it finished charging. Also, doesn't the car use the Wall Connector for power while the cable is still connected to power things like Sentry or Cabin Overheat Protection or does it use the main battery. That would mean if I wanted the target charge level, to just start charging again in the morning.
