My z1c has a hugh battery drain with KK 4.4.2 after i connected the z1c to my BMW via bluetooth. Even if i leave the car the bluetooth stack is very active - the process StartingObexMapTransaction and the android.bluetooth are eating up my battery. if i simply switch of bluetooth and after a few seconds on again (after leaving the car) everything is fine but if i do nothing after leaving the car the z1c looses 15% battery each hour without using it...

does anyone has the same problem? is the problem a kk 4.4.2 problem that could be solved by downgrading to 4.3?

Same issue here with Ford SYNC, http://forum.xda-developers.com/show...=2722415<br />

It seems the issue occurs also when use with Toyota TG as reported on other forum..

No issues with the built-in Bluetooth of my Citroen C3.

Does your Citroen C3's built-in Bluetooth support text messaging (Bluetooth MAP)?

Aha nope, my car only accesses the address book, no text messaging feature.

Just as I thought, I guess Bluetooth MAP is causing the issue....
