just wanted to share my vampire drain with everyone after being away from my car for roughly one week. I had a work trip and wasn't sure how to manage it, so I charged it to about 75%. From then on, I resisted the urge to check using my mobile app every hour and instead I checked in once a day. Here's the data: 5/5 5:40 PM 240 miles 5/7 6:29 AM 236 miles 5/8 6:07 AM 232 miles 5/9 7:46 AM 227 miles 5/10 6:33 AM 222 miles 5/11 8:54 AM 218 miles 5/11 10:31 PM 214 miles I expect tomorrow morning I'll have about 213 since I checked twice today, but it looks like about 4-5 miles of vampire drain pet day checking at roughly a frequency of once or twice per day. Hope this data is helpful for owners! Feel free to share your data and experiences and your conditions. Obviously every car varies but hopefully it will be a useful baseline for people to compare to. I might add some of my own interpretation to this too : If you assume 75kwh battery and I lose about 28 miles of the 310 capacity, that's about 10% which translates to 7.5 kwh. 7 days x24 hrs is 168 hrs. That tells me that the average idle power to power the subsystems in the model 3 is about 45 watts. Of course it's not continuous because I believe waking your car causes more power to be consumed. Just another interesting way to look at it though.
