In October 2017, Microsoft released a new approach to battery savings. On top of the classic power plans that not too many people touch, they added recently developed power-saving algorithms and technologies. The new power slider is an easy way to increase battery life or use the performance throttling mechanisms that exist with modern processors. But how well does it work? Quite well, actually.

On PC’s there are four options when on battery power:

Best Battery Life – Battery saver is activated and some Windows 10 features are disabled or act differently. Screen brightness is reduced to conserve power and throttles back processing heavily. Automatically activated if PC drops below 20% battery.

Better Battery – Extends battery life longer than the default power plan but does not reduce screen brightness.

Better Performance – The default slider position and a good balance between speed and battery life.

Best Performance – Focuses on performance only. Throttles up the processor as much as possible.

Best battery life will slow down the PC and best performance will speed it up. To change the power mode, simply click on the Battery icon in the taskbar and drag the slider to the desired power mode that you want. When plugged into a charger, there are only three options instead of four.

Now, you may be asking, “Why would I select ‘Best Battery Life’ when I’m plugged into a charger?” Microsoft hasn’t given an answer to that question yet.

Note: Not all Windows 10 PC’s will have this feature. Windows 10 version 1703 or later is required. It may also depend on the manufacturer and hardware of the PC.
