Default Does 4G go into like sleep mode if not using it?

My phone drains 5-6% in an hour when I am on 4G but doing nothing. Is this normal? It is Galaxy S Relay 4G i415 installing mpj battery as the stock was disappeared. Does 4G go into like sleep mode if I am not using it?

If you are on CM11, this is normal

I'm not sure about the CM11 nightly, but the battery decrease seems quite profound. Try using LiquidSmooth by reventech. The ROM is super stable and has amazing battery life compared to CM11

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.
