Tesla phantom drain (vampire drain): a remote check that shows what is keeping the car awake

Some idle loss is normal — Sentry Mode, Cabin Overheat Protection, preconditioning and third-party apps all use energy. But if your Tesla loses far more overnight than it used to, a remote Toolbox review can look for alerts and system behavior that point to a real fault instead of a settings issue.

FAQ

How much phantom drain is normal for a Tesla?

It varies with settings, climate, and features. A small loss per day with Sentry off is common; sudden large increases with the same settings are worth checking.

Can you fix phantom drain remotely?

We diagnose and document; we do not repair. Many cases end with a settings or app change you make yourself; others point to a part a local shop replaces.

Do I need to leave the car somewhere?

No. You click the approval link in Tesla’s email; the car stays with you and must be online.
