Battery losing juice?

Has anyone else experienced the loss of starting power after leaving your door open for ~20 minutes? This problem is easily reproduced simply by, well...leaving the door open long enough to do a good interior wash and vacuum. Is this just me and mine?

All of the lights are supposed to power off automatically after a period of time to prevent battery drain so something is probably wrong if you have noticeable drain.

The battery should not be affected after 20 minutes. I did a full detail on my Titan, left the doors open for about 5 hours, and saw a noticable impact on the battery. My Audi's electrics automatically power off after about two minutes of the doors being opened. Wish the Titan did the same.
