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.
1. Check these first (free)
- Sentry Mode, Cabin Overheat Protection, and scheduled preconditioning
- Third-party apps or telemetry services polling the car
- Recent software update or newly fitted accessories (dashcams, USB devices)
- Cold weather: battery heating can raise parked loss
2. What our remote check adds
- Alert history around the periods of drain
- Low-voltage / 12V behavior that often hides behind “drain”
- Signs the car is failing to sleep, when Toolbox exposes them
- A written PDF with screenshots you can show Tesla Service or a shop
3. Honest limits
- We cannot measure current draw with a clamp meter remotely
- We do not change your settings or install anything
- If findings point to hardware, the repair is local — we give you the evidence

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.
