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?
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?
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.
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.
