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.

          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.

    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.
