This push twice is actually a step backwards for BMW. Prior models were a short push left the car in Option (radio mode) and one longer push for about two seconds turned everything off. In 2012 and newer you are either required to push twice or according to the manual push once and then lock the car.
One of the diseases of many high end cars is how few miles we put on them. With all the electronics and the power required to start these beast it must take quite a bit of time to recharge the battery. I've noticed that if I'm travelling for a couple of weeks the battery warning rears its ugly head until I drive a long distance.
