Battery (System Preferences)

The Battery pane (also known as Energy Saver) of the System Preferences in macOS was developed by Apple to allow users to customize the power usage settings of their Mac.

History
With the first release of Mac OS X, the Energy Saver preference pane superseded the Energy Saver control panel from classic Mac OS. Starting in MacOS Big Sur (version 11), the pane will appear as "Battery" instead of "Energy Saver" on battery-powered Macs.
