'twas the same for me. Today I've turned off second cpu core and now the drain is more or less comparable.

Make an init.d script and put the following in it:

echo "0" > /sys/devices/system/cpu/cpu1/online

How much screen on time do you get?
Did you use it all the time before capturing that screenshot or was it idle?

I did normal usage on it, or let's say the same as any other day. Using WhatsApp mostly. My stock ROM gives me at least 19h without using stamina mode, CM give me a good day from a new installation, but after day two I get this battery drain.

The next time it happens, take a screenshot like this, a screenshot of the graph when you first get into battery usage...and also take a screenshot of your screen on time (you get to it by tapping on "screen" in battery usage tab). Because if you get around 3:45 - 4:30 hours of screen on time, it's not bad battery life but actually maximum of what our phone can get.
