This has been a long standing issue with my 2019 Model 3 LR. When I park the car with the battery between 60-70%, it loses substantial charge just sitting there. For example, today I parked in my 65 degree garage with the battery at 67%. An hour later it was at 63%. Sentry was off and no one touched the car during that time. The car’s energy app attributes this to “vehicle standby.”
This only happens between 60-70%. At other battery levels no charge would be lost.
My best guess is that this is not real battery drain but just inaccuracy in the battery gauge. Back of the envelope, the car would have to draw 3 kW to drain the battery 4% in an hour, which seems unlikely.
Has anyone else seen behavior like this?
