No it`s not normal. I suggest you get an app like kernel toolkit for example and check your CPU settings. The app BetterBaterryStatus will help you to discover the culprit.
You could also reflash the kernel using recovery, in this case you will be able to verify the kennel settings in aroma Installer before installation.

Thank you for your reply! I downloaded BetterBateryStats and the "Awake (Screen Off)" is at 91%. Is there any way I can find out exactly why and solve this, without flashing the device?
EDIT:
I don't have TWRP installed as I used only "UniKernel v8-0002 ODIN FLASHABLE" to flash my phone via Odin. Can this be the reason. And do I have to install TWRP to fix this?
I saw a deep sleep fix in the thread below. Do you think it may work?
