MacBook Pro screen brightness changes by itself

I have seen this question asked before but it never seems to be resolved, so just asking if this is a universal issue? Basically, I like my screen bright and set it to full brightness but every time my computer sleeps it defaults back to a particular brightness.

Do not have "automatically adjust brightness" or "true tone" selected

MacBook Pro 13″, macOS 10.14

In the Battery (or Energy Saver for older versions of macOS) System Preferences and disable the setting for "Slightly dim the display". When the laptop is on battery power the display's brightness will reset to the lower setting to help with extending battery run time whenever the laptop sleeps or logs out. I also find this an extremely annoying feature/setting as it should at least respect my custom setting and return to my custom setting instead of going back to some unknown macOS default setting.
