Default [Q] [LIVEVIEW] Battery Issue with Galaxy Note II 4.3

Hello (sorry for bad english)
I have LiveView M800 since few days...
I have Galaxy Note II. When I was in 4.1.2 LiveView worked perfectly (~15hours)
Now I am in 4.3 (MK4 firmware) and the battery is empty after 2 hours without use (just connected)
And I have friend has exactly the same problem (works on 4.1.2 and not ion 4.3) so it's not just a problem on mine
Is there a relation with Bluetooth Low Energy on 4.3???
Any ideas for a solution?

Sorry for bad english...
