Why does my car lose range while parked?

A parked Tesla uses very little while it sleeps, and more when something keeps it awake. The most common causes:

• Sentry Mode, which keeps the car awake as long as it’s on;
• Cabin Overheat Protection or scheduled climate;
• cold weather: the battery warms itself, and the displayed range also drops with the temperature;
• an app (Tesla’s or a third party’s) or an accessory that checks on or wakes the car often.

In the Parking tab, each stop shows what the car lost meanwhile: compare a night with and without Sentry Mode to see the difference.

Copeel itself lets your car go to sleep as usual and only rarely wakes it: see Does Copeel drain my car’s battery?.
