When idle for some (I'd say random) time the screen dims automatically on battery but when using the mouse/keyboard again it doesn't automatically restore the previous brightness level.
Sometimes this is only triggered when moving the mouse (maybe other activities as well) after some idle time.
Also the screen is sometimes set to the lowest brightness level, other times just to (seemingly?) random levels.
Sometimes even blacks out for a fraction of a second while doing so.
