What is Battery Saver?

Windows 11's Battery Saver helps conserve power on laptops and tablets by reducing resource usage when running on battery. Restricting certain features extends battery life and helps squeeze the most runtime from a single charge.

Battery Saver usually triggers automatically when the battery reaches 20%.

Why Lower Your Screen Brightness?

Dimming the display when Windows 11's Battery Saver is active helps the laptop last much longer on a single charge. Displays consume considerable power, meaning lower brightness saves a significant amount of energy. Windows 11 provides controls to fine-tune how much the screen dims.
