Omni is also quite a bit better on idle battery life than CM11. I've clocked my phone as getting about 60 hours on one charge with moderate - low use. But to answer the original question: Yes, the phone goes into Deep Sleep when not in use. You may have other apps taking wakelocks that make the phone come out of this state periodically. check out cpuspy and wakelock detector if interested.
