Default [Q] CM 10.2 BlueTooth Question

I have been using CM 10.2 (10.2-20131102-SNAPSHOT-M1-xt925) for about 1 month. Everything run fine and smooth. However, when I turn on BlueTooth, battery drop fast. Without BT enabled, phone could run to 2.5 days. With BT enabled, phone just last for 1 day or a little bit long; definitely less than 2 days.

Is this battery usage normal with BT enabled ?
Is there any more builds after this 11/2/2013 for CM 10.2 ?

Thanks,
