iPhone4S battery killed by bluetooth infinite loop

Hi guys,

In the last few days, I noticed that my iPhone4S battery kept running out of juice in less than 3 hours after I walk out of my house.

Then, I noticed that when I am driving, the phone would get into an infinite loop doing these:
  1. Transfer entire ContactList to iDrive via Bluetooth
  2. Bluetooth loses connection
  3. While this is going on, the SOS green light would turn ON/OFF
  4. goto Step [1]

It'll do this until I get out of the car. By that time, the battery would be almost zero.

Any idea if the iPhone4S Bluetooth interface is faulty or is the iDrive Bluetooth is flakey? Have you guys seen this before?
Not sure if the new iOS 6.0.1 upgrade has anything got to do with this.

I called Apple, they said to check with BMW to see if they need to update anything on their end.
