This tutorial will show you how to turn on or off energy saver for all users in Windows 11.
Starting with Windows 11 build 26002 (Canary), Microsoft is introducing energy saver, which extends and enhances battery saver. It is an easy way to extend battery life and reduce energy use by trading off some system performance. It can be toggled on and off or configured to run automatically whenever the device reaches a certain battery percentage. While optimized to extend battery life, energy saver will be available when PCs are plugged in (this also includes desktop PCs) for those aiming to conserve energy all the time.
Display brightness is automatically reduced up to 30% by default when using energy saver. You can specify the percentage value to scale brightness to when energy saver is turned on. You can also turn on or off Lower screen brightness when using energy saver.
Starting with build 26020 (Canary), for PCs that are plugged in and do not have batteries (such as desktop PCs), when you turn on energy saver, we are trying out a new energy saver icon that is shown in the system tray to indicate energy saver is on. For PCs with batteries, there is no change to the experience, and you will continue to see the leaf icon overlayed on top of the battery icon in the system tray.
Starting with Windows 11 build 26200.5001 (Canary), after trying out a different design for the energy saver icon in system tray a few months ago for PCs that are plugged in and do not have batteries (such as desktop PCs), Microsoft reverted the design back to the leaf icon a few builds ago. (This change is also present in Build 26100.)
Starting with Windows 11 build 26120.1340 (Dev), build 26100.1876 (RP), and build 26100.1882 (24H2), for laptops on battery, a notification will pop up asking you to plug in your laptop if the battery level reaches 20% while Energy Saver is set to “Always On”.
