Battery question on Pixel with Android OS

[Roose00]

I have been seeing Android OS using most of the battery. By the end of the day the screen may make it to top of list but what concerns me is that it is being kept awake hours by the end of the day.

I did try gsam battery stats. It shows double the battery drain while screen is off compared to on.

Any thoughts on what the Android OS is being kept awake by? Is this normal?

I attached a pic of battery usage by Android OS. Does that show up for everyone to see? I can't see it
