10% battery drain overnight?

[Dionysius]

Hey all,

new model 3 owner here. I wanted to post about this for advice because I’m really scratching my head right now. Every morning I’ve been waking up with about 10% battery drain on my LR AWD overnight. I know this isn’t normal, so I’m trying to figure out what could be causing it. I’m in Southern California so temp shouldn’t be a factor.


Any ideas?

Do you have Sentry Mode activated overnight ?

Sentry mode, summon keep awake (forget the actual name for this setting), third party apps...

There are a lot of things that can cause the car to stay awake, which then causes so called phantom drain.

Sentry mode is disabled overnight

As Runt8 mentioned above, do you have any 3rd party apps running ?

only real way to know is to purchase one of the third party apps to identify exactly where the loss is coming from.

Summon standby mode will also prevent the car from sleeping. To turn off, go to settings -> Autopilot -> Standby Mode (under Summon) and either turn it off or set 'Exclude Home'. Keep in mind that, as it gets colder, the car will use some energy to maintain minimum battery temperature, so it's always best to plug in when you can.

In my S I have noticed that if I make a long drive so that the battery gets all toasty warm, and then park the car overnight, the drop in battery temperature from 100F (???) to 50-60F will make the car show a significant drop in percentage. The worst I've seen is an 8% drop in an hour while shopping for groceries. That was after a 3-hr drive and then parking at the store with roughly 30F temps.

Yep, I was losing a ton of range overnight while on a week long trip. Shut off sentry and summon standby. All is well again.

No third party apps! But we’ve been on a long road trip (1200 miles) and will be getting home to Phoenix tomorrow. So perhaps it’s just better temperature related

Suggest double checking that Summon Standby is disabled. It's a power suck.

I don’t have FSD so I don’t have that option unfortunately
