In my case, I have a 2012 that bought new last August. It's never had any battery issues. I keep it on a battery maintainer when not drivien daily. I'll be curious to hear what a dealer service department has to say.

 

The dealership, took and looked at it, and they said it is normal. Once you unlock both go windows go down minimally and then more if you pull the handle.
Once your turn on the ignition if both doors are closed, both will "tick up"
If driver door is open, it will close up when you close the door and the other will "tick up"

 

Yup, normal.

 

One more point, if you open/close the passenger door before starting the engine, the passenger window will not move. You can open/close the passenger door the day before, leave it overnight and the next morning when you start the car, the passenger window will not move. I would call this a "bug" in Porsche software.

 

Good pick up, it explains some of the "inconsistencies" that I had in explaining why and how things happen
