We got the increased battery discharge message on our 2011 50i several times. Ours is a bit more than three years old, and has 31,000 miles. When our dealer, BMW of Bridgewater, heard the message we were getting, they squeezed us in right away, and replaced the battery under warranty while we waited.
Here is what the receipt from the dealer service department says:
Verified CC message for battery discharge. Connected battery charger and ran vehicle test. Ran energy diagnostic but test plan was inconclusive in terms of battery state of health. Connected midtronics tester and found battery in need of replacement. Need to replace battery. Replaced battery and registered new battery.
