Microsoft is testing a new adaptive energy saver mode in Windows 11 to improve laptop battery life by automatically enabling or disabling the main energy saver mode based on the laptop's workload.
The traditional energy saver mode in Windows 11 reduces display brightness, disables transparency effects, stops background apps, pauses non-critical Windows update downloads, and limits syncing of certain apps like OneDrive and OneNote.
The new adaptive energy saver mode will be available only on devices with a battery, automatically turning on or off without affecting screen brightness to make it less noticeable on laptops, tablets, and handheld devices.
This feature is currently being tested with Windows Insider testers and is expected to be added to Windows 11 later this year, but it won't be available for desktop PCs.
