I charged our Model 3 to 80% 248 miles and unplugged before vacation closed the app on both phones until we were back home, 12 days later it was still at 214 miles. Pretty good, My Model S ate more miles than that.
The car has been at the service center since April 24th. (that was the second time it was there). Originally went in on April 11, and it was there for a week. Got it back for a few days and then it went back in, has been there for 72 days now (as of 7/5/18). Ya, it's nuts!
I only got to really drive my car for 2 weeks total since ownership back in March!Only have 1100 miles on it...
Wow, 72 days in the service center??!??!?!!
Have you gotten your car back yet? Do they keep you posted on the status? Did you send it in just for the vampire drain or for other issues as well?
Vampire drain seems to have gotten a lot better now. I notice the app causes it to wake up much less often. Sometimes I'll check the iOS widget and it will say "Asleep. Last updated (sometime the previous day)." even if I have driven the car 70 miles since.

So begins my experiment on reducing my car's vampire drain. Just changed my Tesla account password in order to invalidate the token that teslab.com uses. Verified that my teslab account now says "Your Tesla credentials are no longer valid and vehicle logging has paused.". Range is currently 190 miles. Will see what it's at in the morning.
87 days now.... Close to a quarter of a year. Originally went in for Vampire Drain, bad AC, and some cosmetic QA stuff. Everything has been fixed except for the vampire drain. They're still not sure what's wrong with it.

Yes sir. I will pull in and note miles and sometimes I can let it sit a day or two. I may check once via the app but normally just open the door. One pain point however is the app rarely works. As the car seems to be in a deep sleep.

Crazy... I assume they gave you a loaner car this whole time?
Can’t they (or have they already tried) just swapping out the battery?

So after 8 hours I only lost 2 miles. Much better than the 6 or 7 miles I used to lose overnight in the same length of time. Parked at work at 10:15 with 173 miles and will be checking every 2 hours or so.
Will probably only have two data points today.as I'm planning to start charging around 3:30.
I recommend NOT checking every 2 hours... wait as long as possible before checking. Check only when you need to use the car. Just keep track of how much times goes by. If you keep checking every 2 hours, you will wake the car every 2 hours, so you will have more drain that you would typically get if you weren't checking and it will skew your numbers.

I've been checking every 2 to 3 hours during the day since i started monitoring the drain. Changing the time interval that I've standardized on will skew my previous data. I'm a memory test/product engineer so I understand consistent data collection .
No loss in range since 1030. Before it would have been 2 miles. Can't believe how much power was being sucked up from enabling a simple monitoring app.

Ya, the apps constantly wake the car, and every time the car wakes it drains a significant amount. So once you collect your numbers following your methodology, I would recommend checking after 12 hours (more similar to what most people here have done), and multiplying that number by 2. Or checking after 24 hours. To get a good idea of how you compare against the rest and see how much energy you lose every 24 hours without constant checking. Anywhere from 0-5 miles is typical, with most people being around 2-3 if the car is kept indoors in 70-80 degree garage.

Gotcha. During the time I was on teslogs, and even when checking my range every hour, I would usually see the "waking up" message in the Tesla app. Implying that the car was in the power down mode. Do you know what the time interval is for the car to enter sleep?
Just now I checked my car. Saw the waking up message. It's only been about 30 minutes since I last checked. It still has the same 173 miles as it had 3 hours ago.

The interval for sleep was not released by Tesla. There are lots of factors though. Has to do with your battery temp and stuff, so it depends on if you were just driving or not, the ambient temperature, etc. So sometimes it might go to sleep after 10 minutes, other times it can take 45 minutes to an hour.
Can you force it to sleep with the “Power Off” button? Will that force it to sleep immediately?
How bad was your vampire drain that it prompted you to take it to the SC?
I think I am losing 1MPH on average. 24 miles per day seems excessive. I am going out of town for a couple of days so will be interesting to see what drain I get when I get home Monday.
I’m not mad about it...I can plug in. I didn’t think about it until I started reading posts...lesson there I’m sure, lol. I thought it was a little funny to use more energy sleeping than driving and I don’t consider myself a granny driver. I’ll check overheat protection setting though I’d probably leave it enabled to do its job. I do appreciate folks talking about this stuff though so I can understand how the car operates/reacts.

For my second data point today at 1450 I still had 173 miles. Didn't get a chance to charge the car this afternoon due to work so my somewhat longer third data point at 1820 shows 171 miles. Only lost two miles in 8 hours.
