Same is happening with mine - rapid run down from 15K to 6k though I only have 1600 miles on my '13 535xDrive. Check your dealer to see if the service bulletin addressing the software issue that is causing this has been released yet. My dealer said he expected it in March.
My opinions are free - you'll get exactly what you pay for!
