R1T and Model Y (previously a 3 and X)
Ours is a 2017, and we see 20s/30s but usually 40s overnight. Just like summer I've seen 105, but right now mid 80s to upper 60s at night.

I was putting stuff in the garage and I could hear the T's front louvers and other electrical gear powering up and moving when it had been off for 4 days except me reading miles remaining once per day. I would have hoped that by now they would have figured out a lot of the drain, but alas no. There's even a story on here about a power steering pump being energized and running continuously when the truck was off. That's great for vampire drain, sarcastic, and future reliability of the pump.
Makes sense with a 2017. That is what we saw on our 2017 X as well. Our 2018 3 has less. And our 2022 Y has virtually none.

Did another, longer test at the airport. Since this was longer, rounding of the state of charge display should have a smaller impact.

Temperatures: 40's - 70's
Gear Guard: on (380 videos recorded!)
Time elapsed: 163 hours and 15 minutes (6.8 days)
Starting state of charge: 80%
Ending state of charge: 68%
Calculated average power consumption: 99.2 watts (pretty consistent with last natural test)

I will note that my estimated efficiency on the way home from the airport was lower than average (in all purpose mode, ride height at low). Could have been due to some battery conditioning or heating.

Small test here.

Left truck at airport parking garage during a trip.

Temperatures: mild
Gear Guard: on (lots of videos were recorded)
Time elapsed: 67 hours
Starting state of charge: 74%
Ending state of charge: 69%

This works out to an average power draw of just over 100 watts. This seems reasonable given that Gear Guard was on.

For nearly 7 days with gear guard on that’s really impressive.

Minor data point here. R1T sitting in driveway at home with mild temps….low 80’s yesterday afternoon down to mid 50’s last night. GG off (at home), PAAK on, SW version 2022.31.5. Lost 1% in the last 24 hours.
Pretty good right?

The 380 videos...are most of them someone casually walking by...or an actual "casing" of the vehicle?

I didn't go through them very closely. None of the thumbnails looked like people checking out the vehicle. I've definitely seen clips of people scoping it out at other places. Maybe it is that I was backed in or that people at the airport are in a hurry, tired, or both... Or maybe I was tired after 12 hours of travel and just didn't notice. ?

Happy for you. I have no doubt it's better than Rivian vampire drain, right now... But I know too many people who admit that Tesla still suffers from noticeable drain -- much more than the legacy manufacturers. I'm sure this is mainly due to a difference in philosophy -- tech company vs auto manufacturer... But it's real, and to say Tesla doesn't suffer from vampire drain is, well, flippant.
Tesla used to have vampire drain issues as well, but in the last few years of software updates, it’s all but a non-issue. Left my 2018 model 3 at airport parking for 5 days and can’t back with 0 loss.
Meanwhile my rivian loses 5-6 miles per day on average sitting untouched. I have no doubt rivian will also turn this into a non-issue over time.

No, it isn't. That's still nearly 2% per day or 2.5 kWh/day.

That’s not ‘just’ vampire drain. That’s including gear guard on which is recording basically every time someone passes by with its surround view camera system and turning on the interior screen to let people know it’s recording. Tesla which now has virtually no vampire drain has substantial drain when sentry mode is on. On a 3 day stay in a hotel with it on I lost 5% a day. So 15% in 3 days. If it was off it would have been less than 1%.

Since Rivian is the only other manufacturer that has a video enabled security system. Comparing the two battery systems drain (based on percentage), again the Rivian is impressive. Now one could argue that the rivian has a battery 2X the size of my Model Y so if we take that actual kw/hr loss they may be more comparable. Still from my experience owning another electric vehicle with video security, that’s quite good.

Fair. But until we see Rivian with less than 1% per day without Gear Guard I won't be satisfied. And to date I'm pretty sure no one has seen that low.

I’ve seen folks report numbers under 1% elsewhere but have not seen that with our truck. I did estimate 0.6%/24 hrs while in shipping mode once but would really need a few days in that mode to be sure.

Yes vampire drain while gear guard is on is comparable to Sentry. What's crazy is that I see absolutely no difference in vampire drain between having gear guard on or off. This seems to be the primary problem.

When it's off, average power usage should be in the 5-15W territory. Not 100W.

Anyone notice just strange noises coming from the car at idle for no reason?

Like - gear guard off, sitting in a garage, at home, not touched for several hours, there's some fan ramping noise that starts getting really loud under the hood like it's doing *something* serious, but for the life of me I have no idea what. Sounds a bit like when it's charging but in this case it's not plugged in. No doors are open, vehicle is locked, etc.

It doesn't happen all the time but it certainly seems like something that never needed to happen in this scenario.
