Help: Horrific battery draining while parked in long term parking structure - I've got 12 days to go

[jcanoe]

In my experience normal loss over 7 days is ~1% to 2%. That is with my 2020 LRMY unplugged, unlocked, no Sentry when parked inside my locked home garage in moderate temperatures.

MYLR is in an airport garage right now. To me it is pretty clear. COP is off, scheduler is off, etc. Only Sentry is on. EXACTLY every 2 hours heat comes on but only for a brief period and not to a certain temp. Other threads suggest to ensure cameras don't fog up. Note the power loss is a straight line decline, and the heating by itself doesn't take a toll. When I drive home and park in the garage Sentry is off, car goes asleep/idle, and basically zero power loss overnight. Sentry has 2 hour heat intervals, but they themselves don't have a huge power drain. "It's what Sentry does"

Update... after 76 hours, I went from 79 to 60 percent (same patterns). More than I'd hoped, but will only cost a couple of bucks in home charging. Worth it for the safety and video.

It's now just a couple hours past 3 days and my car is now at 63% battery. I've lost 16% in about 80 hours parked in a parking structure!!! What the hell is wrong? The car should be going to sleep, right?

I'm very late to this thread, so what I have to share has probably already been covered. I'm not going to read all 8 pages to find out though, so instead I figured I'd just share my relevant experience:

• This happened to me early on in my Tesla ownership days.
• The problem turned out to be dueling data services
• I use TeslaFi, and I had tried out an app, the name of which I don't remember now.
• Both of them are designed to let the car go to sleep and minimize taking it out of sleep
• However, they didn't know about each other, so obviously weren't cooperating together.
• Thus, their check-ins being on different schedules was what was preventing the car from going to sleep.
• The real trick was that I had deleted the app without first disabling data collection. That happens on a cloud server, not on the phone itself. Deleting the app left my creds in the server so it was still polling my car. They app developers were incredibly responsive and helpful given that I had never given them a dime. They said that they have no way of knowing that a user deleted the app.
• TeslaFi has a number of settings related to sleep, and fairly extensive help info on tweaking all of that.
• In my case, once I got removed from the other app, I didn't need to do anything special on TeslaFi, and I have not had a problem since - it's been over 2 years.

@avramd very good point!

I had a similar issue to OP's except that my car s scheduled for a charge port service tomorrow (mechanical issue).

I'm parking my MYSR (LFP battery) in a -1 floor parking garage, where reception is very low, but possible.
My battery went from 53% down to 37% in 5 days. Thats at least 3% per day. Yes I'm checking the App regularily, like every day. But I usually have 1% loss per day with the same checking behaviour.

Maybe Testla is doing some remote data collection, because of that service on friday. And its keeping the car awake because of bad reception. There was no update, or any other info besides that. And I didn't change anything. My last update was in april.

FWIW, Earlier this year I parked my Y in the Ft. Lauderdale Cruise Port covered garage for ten days just a little nervous. Prior to parking I charged to 98% and left the vehicle parked at 92%. I turned off sentry and climate control. I returned ten days later to a charge of 77%. I think a future cruise of 28 days would not make me so nervous in leaving my Y in a covered parking garage.

I regularly leave my car parked at home unplugged overnight, charging every other day. And every time I see the next day it has lost at most 1%, usually it's the same % where I left it.

This seems poor given the setup. What happened, according to the screen?

The energy screen should give an idea of what is happening. If it is essentially uncategorized there could be an issue. But probably something mundane.

That's actually quite bad for deep sleep. Did you have cabin overheat or summon standby on? Do you have any third party apps that can access the car? Does the garage have any LTE reception? One theory is the car may waste more energy trying to find a connection (similar to how a cellphone in a poor reception area can drain battery faster).

On my Model 3 (Intel not Ryzen) I lose only about a mile of range per day, sometimes even less. So after being parked a week I only lose a few miles of range.

cabin overheat

I suppose it is possible it started insanely hot and most of this was Cabin Overheat in the 10 hours it was active.

In any case, very easy to tell if there is any question about it at the time.
