My model 3 long range is sitting in my garage. I charged it to 80% on Thursday night and unplugged it on Friday morning. It’s just been sitting since that time unplugged but undriven. It’s down to 51% on Tuesday morning. Down 30% in 4 days seems kind of bad. Sentry mode is on despite me having it set to not be on at home. Still seems like a lot of energy usage for a couple of low resolution cameras. Anyone else noticed this substantial energy usage when not in use?

Ah righto. First time I’ve left it unplugged for so long without using it. Had no idea the standby power draw would be so high.

Permanently “a few hundred watts” (or something around 300 W according to your calculation) sounds excessive for a passive surveillance system. That’s what a gaming PC uses while playing a somewhat demanding game, or a cyclist going uphill.

It’s not the surveillance system taking 300w to run.
To keep the car powered on enough that the system is working is going to take up most of that power anyway.
You’d have a similar problem with camp mode which keeps the car on, even with the AC and Sentry off.
In a perfect world if they could design the car so sentry gets powered separately that’d be cool, but sentry was an afterthought, and doing something like that with planning might still be completely impractical
Sentry mode doesn’t allow the main battery to sleep and will drain it. We recently left our Y for ten days with sentry mode off, and the battery barely moved.
I don’t know when I’ll have another chance to test this on mine but thanks.
You’re welcome
Ok so I turned off sentry mode last night after posting my last reply.
12hrs later the battery is down 1%.
Need to make sure that sentry mode is off at home.

Yeah that makes sense.
I’ve actually managed to let it sit unused for a few more days with sentry mode off. 48% now.
So this is better to see.
Actually has me wondering about a 4 day trip I did earlier in the year. Got home with air 10% left. Sentry mode was on the whole time. I probably could of gotten home with 40% if I’d left sentry mode off. It’s a power hog.
Sentry mode drains the battery about 1% every two hours, give or take.
No, not even close, even when it’s 100+ after the sun goes down and cabin overheat protection is on.
I’ve read of apps keeping the car from entering standby, although I’ve never installed anything third party and witnessed this myself. Do you have anything like that installed on your phone?
No third party apps at all. Just the Tesla one.
I’ve noticed the car uses about 10% whilst parked in the sun whilst at work which is obviously keeping the cabin cool.

I think your probably right. The only example I can think of that might benefit is the roof lining in a car. I think the daily heat cycle probably is the cause of roof lining dropping. Not that big of an issue with a glass roof.
My Amarok has spent the vast majority of its life under cover. It still looks brand new inside.
My last car spent most of its life in the sun and definitely looked old by the time it was 10 years old. Had to replace the roof lining once.
It seems pretty accurate to me with sentry mode on
Is it in a spot in the garage where sentry mode would be getting triggered and recording a bit? The car essentially stays awake so if you do want to turn it off, you can do so in the Tesla app > Security and Drivers.
Additionally, are you checking the car via the app often or is your garage hot enough that cabin overheat protection had kicked on?
I just left my 2018 Model 3 LR unplugged for a full week and lost maybe 2% so something is definitely keeping the car awake.
It’s in the garage alone with no access for animals or anything.
I think I looked at the car once before today.
I’ll have a look at the recordings if any. See if something is triggering it. Nothing in their to trigger it though so doesn’t make much sense.
Shadows trigger it something fierce, too.
