Microsoft has released an update for Windows 11 that enhances battery life for laptops through a new adaptive energy saver mode. This mode manages power consumption based on the laptop's workload, activating energy-saving features during light activities like web browsing and reducing power during intensive tasks. The energy saver mode dims the display brightness by about 30%, disables transparency effects, and pauses background app activity. The update will also provide more accurate battery estimates and insights into power-hungry applications. Additionally, it includes smarter controls for screen refresh rates and brightness, automatically lowering them when the user steps away. The update is being rolled out in the latest Windows 11 release.
