Windows 11: This Windows 11 feature may help save your laptop battery

Microsoft will introduce a new feature to Windows 11 that is meant to take the battery out of your . to save Laptop and also to increase the screen refresh rates when the system needs it. It is the Dynamic Refresh Rate (DRR) feature, and true to its name, it will attempt to dynamically adjust the refresh rate in your laptop, switching back and forth between low and high refresh rates depending on the application running on the system. In Windows 10 you have to choose between the refresh rates and that remains static unless you change it yourself. This eats into the battery life of the laptop. With the Dynamic Refresh Rate feature built into Windows 11, we have more hope for longer battery life.
The important thing to note is that the DRR feature is for Windows apps and does not support video games; it is different from the variable refresh rate. For now, MS Office apps will most likely get DRR first for scrolling. Other apps like Microsoft Edge, Microsoft Photos, Snip & Sketch, Drawboard PDF, Microsoft Whiteboard, Microsoft Sticky Notes, Adobe Acrobat, Adobe Illustrator etc. will get scrolling and inking support.
While the feature looks promising, you’ll need a Windows 11 laptop with a 120Hz display or more for the feature to work for you. Also required is the WDDM 3.0 graphics driver for the ink support.
To upgrade to Windows 11, your system must have at least 4 GB of . to have RAM, 64 GB of free storage and a 64-bit 1 GHz dual-core processor. Windows 11 is expected to be available for download later this year, when PCs running the Windows 11 operating system go on sale officially.
