How to Disable or Enable Auto-Brightness in iOS 12 for iPhone and iPad

Auto-Brightness is a screen setting on the iPhone and iPad which causes the device to automatically adjust the display brightness depending on ambient lighting conditions. For example, if you’re outdoors or in bright lighting, the screen would adjust to be brighter so that it is more visible, and if you’re in a dim room or outdoors at night, the screen would adjust to lower the brightness so that the screen isn’t as glaringly bright. Auto-brightness in iOS also can improve battery life by adjusting the brightness of the iPhone or iPad display down as the ambient lighting permits.
Some users like to turn off auto-brightness, or to make sure that auto-brightness is enabled on their iPad or iPhone. However, as of iOS 11 and iOS 12, the auto-brightness setting has been relocated from the standard Display settings area to deeper within the settings of iOS. This has led some users to think that auto-brightness was removed in iOS 11 and iOS 12, but in fact the setting was merely relocated.
