Before the latest update to Android 9 I could set my brightness on my G6 to 30% and see fine. Also my battery would last almost there days before i had to charge it.
Since the update i have to set it to 80% and my battery runs down in less than a day. Which is unacceptable.

Are you using adaptive brightness? Can you post a screenshot of the battery usage. Did you do a factory reset after updating to pie?
A good app to help better understand battey usage is gsam battery monitor you might want to try it.
The brightness slider is not implemented the same as it was in oreo. I do not think that your screen is using more battery unless you are keeping it noticably brighter. Best guess there is an app or 2 that have become bad preformers since the update.
As a way to troubleshoot install an app to help monitor like gsam.
