This is one big drawback of Android compared to iOS. It has so many setup settings (witch I love and do not want to give away), but this setting are bad structured. You never know, where some setting is. E.g. this setting is once in general setting of an app. All is set up to show badges, and regular user do not know, there is additional place where it has to be setup to show badges.
Same goes for Always on display (to show time, date and battery status). I would give it under screen and lock screen. But no, it is "hidden" somewhere under battery setting. It has nothing to do with battery - just fact it uses more battery if used, means nothing. All apps use more battery if used.
