Phantom draw

What is the cause of my phantom draw while car is parked? Is that battery conditioning?

Earlier this winter I observed a similar drop is state of charge (SOC) of the battery in my 2020 LRMY while parked. I attributed this overnight low temperatures <28F where in the past my Tesla Model Y will lose 3% SOC overnight due to lower cold weather battery performance. Also, cell balancing could be the source of the drop in SOC. If this persists try rebooting.

If you tap on the “Park” tab it should give you a breakdown of what used energy when parked. But most of the time it’s just used by “Vehicle Standby” which doesn’t tell you anything.

Sometimes my Model 3 loses 1% or less in 24 hours while parked, other times it loses nearly 4% in just my 7-8 hour work day.

Phantom draw continues. Could be balancing or battery heating. I park outside.

Have you tried rebooting?

What is the version of the Tesla software?

In my experience other than when preparing to charge my 2020 LRMY will only perform battery warming while Preconditioning via the Tesla app. If cold enough battery warming can take place even if my Model Y is not plugged in while Preconditioning. I have recently observed battery warming while plugged when Preconditioning via the Tesla app at the end of a 90 minute Level 2 charging session where I would not have expected battery warming to be needed or take place.

These pic were last night when I got home. I’m starting to think it is sentry mode!

It’s 100% the sentry mode. Search for many posts on the subject.
