If you're in Eco Pro mode, the discharge rate is much much slower, but you can feel the cabin temperate cycle a few degrees warmer and cooler of your set temperature.
Either mode is a huge win over non-hybrid start-stop and I guess you can choose whether you want to save a few drops of fuel at the expense of feeling slightly warm while stopped. I love turning off the radio when I'm stopped to bask in the silence of this car!

If BMW is really cycling the LiOn batteries down to 10% then lifespan will be reduced. LiOn batteries actually prefer to stay charged. Life is longer when they are charged before being depleted. Very different than NiCd and NiMH.
