Again, borrowing from the Battery section in iOS Settings, Big Sur's Battery section displays the battery level over the past 24 hours or the past 10 days, as well as information about when it was last charged.
The section also features a graph on power use, but unlike the iOS Battery feature it doesn't show which apps are the main draw on the battery. It also lacks the iOS Battery Health tool.
Another battery feature is Optimized Battery Charging, designed to reduce wear on the battery and prolong its lifespan by "ensuring a MacBook is fully charged when unplugged".
"Optimized Battery Charging learns your daily charging routine and activates only when your Mac predicts that it will be connected to a charger for an extended period of time," Apple explains.
Users will also see this design change in apps like Finder and System Preferences. Apple notes MacOS 11 adds support for iOS user interface features to help streamline the app design process across mobile and desktop.
Another major part of this plan is Mac Catalyst, a tool for developers to quickly port iPadOS apps to MacOS. Apple used Mac Catalyst to build its revamped MacOS Messages app, which now has all the modern features of Messages on iOS.
MacOS Spotlight finder and launcher is also getting revamped with faster access, and streamlined results. It introduces support for Quick Look which offers a preview of the document as well as the ability to rotate, crop, and mark up images, sign PDFs and trim media files without launching an app.
