Model 3 vampire drain log

Yeah, because I can watch in realtime I can see the 'low' points. The fridge cycles are surprisingly long.

It isn't a problem. Attach for an hour and use the average power

Exactly.

There's nothing "advanced" about being wasteful.

Completely agree.
I am quite amazed at how much electricity my Model 3 uses, especially when compared to our e-Golf on the same routes at comparable speeds. With the Golf, using regen and sensible driving, I can arrive back in our garage with more remaining range after about ten miles than when I left. With the Model 3, using the same driving style, I arrive back home with 15 miles less range per 10 miles driven. And I thought the Model 3 was supposed to be so efficient?

Also overnight, the Golf hardly loses any range while the Model 3 loses about 4 miles per night. Is this normal for a Model 3 parked in a garage at average temperatures of between ten and twenty degrees Celsius?

Sounds like you’re comparing apples and oranges a bit here. I’ve never driven an e-Golf, but based on your description it sounds like it uses a “dynamic” range estimate that factors in your recent driving efficiency to predict your remaining range. In contrast, Teslas don’t factor in recent driving history and only give a “static” range estimate based on the vehicle’s EPA rated efficiency.

Nevertheless, what you’ve described indicates that you typically significantly exceeded the e-Golf’s original estimated efficiency from the beginning of your trip, whereas in the Model 3 you do significantly worse than the EPA rated efficiency. But without more info about driving behavior, climate use, etc., it’s hard to say why this might be.

Also overnight, the Golf hardly loses any range while the Model 3 loses about 4 miles per night. Is this normal for a Model 3 parked in a garage at average temperatures of between ten and twenty degrees Celsius?

4 miles lost overnight sounds a bit high. Over how many hours is this?

Per the manual, about 1% (~3 miles) loss per 24 hrs is “normal” in moderate temperatures, although it does seem to vary unpredictably sometimes.

These losses are typically worse in hot or cold temps, or if Cabin Overheat Protection is turned on (even if it doesn’t use any energy to actually cool the cabin), or if Sentry Mode is turned on, or if you use a third-party app to pull data from the car and may prevent the car from entering a “sleep” mode. So first thing would be to make sure none of these things are going on.

As for Cabin Overheat Protection, Sentry Mode or third party monitoring apps: no on all three counts, don't use any of these. Don't even use the Tesla app regularly. I switch off Bluetooth on my phone in the evening when I know I won't use the car anymore that day, the car is parked in our garage right next to the e-Golf. It is an enclosed and insulated (though not heated or air-conditioned) garage with ambient temps between around ten and twenty degrees, depending on the season.
Oh and the cars usually sit there unused between about 8pm and between 6am and 8am, depending on when we have to leave for work.

As for efficiency during driving, I explicitely tested this on a route of around ten miles I use very often, from a neighbouring town to back home. Like I said, with the e-Golf I arrive back home with either the same remaining range as when I left or even a little higher, due to regen. With the Model 3 I lose about 50% more miles than what I have actually driven. I used the same driving style, top speeds, acceleration etc.
The problem with the Model 3 is that it is very hard for me to actually grasp the energy usage/effect of regen etc. versus distance driven, acerbated due to the fact that the Model 3 doesn't appear to have a standard odometer that is visible at all times.

On the e-Golf, the left part of the active info display (which on ICE versions shows the rev counter) shows very detailed information about energy usage, regen, current/overall average consumption, remaining range, etc. The display also shows the distance driven on the current trip and/or the overall mileage of the car. It is also easy to see the effect of the regen. When you drive, the hand of the dial moves either to the left (the green section) during regen or to the right (the blue section) during acceleration. The display when not in motion looks like this:

By the way "Verbrauch" means consumption and "Reichweite" means range.
The icons to the right of the trip info are part of the lane departure warning system and the active steering system. (Yes, the e-Golf also has kind of an "Autopilot", at least a basic one. It can at least drive and steer by itself.)

On the Model 3, all I could find up to now was the energy graph, but all the other info that is visible in the e-Golf is hidden somewhere else or doesn't appear to be available at all. Plus, I have never seen the remaining mileage go up, even during longer phases of heavy regen, which I found kind of strange.

What I find most peculiar is that the total mileage of the car is only visible on a sub menu that also shows the software version of the car plus all the Easter eggs. I would have expected to find that on the main screen, on the top left somewhere next to the current speed, gear selection etc. Or is there a way to customize this? I haven't seen any possibility to do this yet.

My experience was just the opposite. After a seven hour trip, and a couple of stops supercharging, my car arrived with 115 miles range left.
The next morning when I checked it had increased to 119! My only explanation is, the stop was at a casino, and overnight my car won some free miles

Tesla has always been more minimalistic in their approach, they don't show too much on their screen (except of course they love to show all the cars the AP sees).

I have had my mileage increase but typically only during long stints of downhill driving.

For Verbrauch/Reichweite, there is a line just under the speedometer. Black to the right shows consuming, green to the left shows regenerating. A dotted line also shows if either regeneration or power is limited.

Total mileage is available on the consumption card (left card). Scroll the card to the bottom and it shows the odometer.

Ditto what TT97 said about the power flow being shown (albeit, minimally) in the top-left of the screen.

And you can also view the trip information cards in the bottom-left corner to see trip distance and trip average efficiency, and/or you can display the energy graph on the rest of the screen.

Thank you both for the information.
I had looked through the online manual on the centre screen, but must have missed that. I will read the pdf version on my computer as it appears to be much easier to use. The one in the car sometimes jumps to detail pages that are totally unrelated to what I had highlighted/clicked before. Possibly a bug.
