Slow Battery Drainwhen Parked

[Mr-T]

i have noticed, that when I am not connected to a charger (like in the parking lot at work) it seems that the battery level decreases about 2 mph. Climate control is off, Sentry mode is on. What could be causing this and what can I do to stop it?

Sentry mode consumes a fair bit of power.

Sentry mode (2 ish miles per hour of power usage).

Sentry mode keeps the car awake and uses several hundred watts continuously.

Thanks. I didn’t not realize Sentry mode was such a power pig. I just got my M3 about a month ago, so I am still learning. . I turned off Sentry mode just after I ousted this and, indeed, the power drain has stopped. I guess I only use Sentry mode when I feel it’s needed. Thank you all. Your answers were very helpful

I don’t know it’s so cheap that I leave mine on everywhere except home because my car is in the garage.
