In the Canary channel build 27686 update, Microsoft has made a series of optimizations to increase battery life for Windows 11 devices. These improvements not only help users work more efficiently with each charge but also contribute to reducing dependence on power sources, especially in situations of moving or working outdoors.

Microsoft has encouraged users to experience and send feedback on battery saving capabilities through the Feedback Hub application, so that it can continue to perfect and improve the product in the future.

One notable highlight in this update is the new "Power Mode", which allows users to customize power consumption based on the device's power status.

For example, when the computer is plugged in, users can select “Best Performance” mode to achieve maximum performance. Meanwhile, when using battery, users can switch to “Best power efficiency” mode to extend usage time.

This flexibility not only helps users optimize computer performance according to their individual needs, but also contributes to extending battery life and minimizing environmental impact.

In addition to improving battery life, the build 27686 update also brings a series of other important upgrades. Typically, there is better support for HDR technology, improved FAT32 file system, upgraded Windows Sandbox - an important tool for developers and users who require a safe testing environment.
