In September 2013 I received my first S85 and ever since I've driven 250.000km (155,000 miles) on the ODO. 5 years later, this September, I received my new S100D and my wife now drives the S85 from 2013. I still love both cars, but the Vampire Drain is still the thing which bugs me the most. My wife drives a lot less per week then I do, so we usually charge her car once per week. It charges to 340km on 90% and a couple of days later it's down to 328km of range. Yes, I'm aware of: - Power Saving settings - Not checking the car with the App - Always Connected checked Off But still, a Model S has a high vampire drain. Even my new 100D has a high vampire drain and looses a couple of KM per 24 hours. Imho this is still a major flaw in the design of a Tesla. We park these cars in a public parking garage with charging options, but we can't have them plugged in 24/7 as we share the chargers (22kW!) with other persons. A Lithium-Ion battery doesn't have a lot of self-discharge and other EVs do not seem to suffer the same problems. The computers inside a Model S/X/(3?) are the consumers here and keep draining the battery. Leaving a Model S/X parked somewhere for two weeks has a serious impact on the range and to me that's unacceptable. I do not think Tesla can fix these issues with software as it's probably a hardware issue, so I'll be stuck with it. But that doesn't make it less annoying. Are there other owners who see this as a major downside of owning a Tesla?
