Android 8.0 Oreo vs Android 7.0 Nougat Walkthrough: What to Know

Improved Battery Menu in Settings

Another aspect where the settings menu is vastly improved is once you navigate to the Battery section. While they returned a breakdown of individual app usage, like we had before, Google also reorganized it so it's easier to use. 

Things you'll likely look for often, like adaptive display brightness, battery saver mode or how long the screen stays on before it goes to sleep are displayed near the top of the battery page. Instead of in another menu completely, or just outright missing. 

Then below those, you'll see app usage and be able to tap an app to see an advanced breakdown of how much battery it's actually consuming.
