Do you have any accessories plugged in ? Phone charger, dashcam, wireless android adapter those kinds of things ?

My 13 year old Volvo has a shutdown pull of 20mA, no modem, not connected vehicle.
I have two 2020 cars, both have 4G modems and are connected vehicles with associated manufacturer apps. Both those cars pull 0.23mA - 0.25mA and can drain the battery to the point the car cannot be opened in less than three weeks from a fully charged, on a new battery. With accessories plugged in my EV 12v battery can be dead overnight.
