Just reboot it. This happened to me a couple of times. After reboot it went to sleep like it should.

i had some instances with stock kernel where overnight it was awake all the time but battery info or gsam didnt show a thing.
Then there's some times Screen is on for a long period, but it doesnt show the phone cpu awake while so.
Strange stuff Couldnt wrap my head yet around it

Sorry, but I think you are being a bit paranoid here...1% per hour is fine ! This phone does not run on air, it needs battery to stay connected to the GSM network. If you want better results, uninstall all your social media apps and try without them for a night...then go from there.

I'm being paranoid because in my note 8 i lost only 2% Totally..so doesn't that phone stay connected to the GSM network? only this phone connects to the gsm network? and does note 8 run on air? or only this phone? #no_offense #peace

Yes. Actually when advanced optimization is active, the OS takes up battery to close background apps to bare minimum(might not receive notifications). The phone is awake due to OS trying to close apps which are unnecessary. Hope this helps!

I always turn off my device during night, it has the alarm that automatically woke it up so it's very useful to save battery life
