Battery and power

Check the battery and choose a power profile.

Battery and charging state

Open Settings and choose Battery and power. If your device has a battery, the page shows the current level, charging state and, when available, the remaining charging or running time. On devices without a battery, it explains that no battery was detected.

Brightness and night light in the battery panel

Switch on Show in the taskbar at the top of this page. The battery icon then opens a panel with battery level, power profile, a brightness slider and Night light, which warms the screen colors so it is less glaring in the evening. For monitors without software brightness, WinDoesNot uses DDC/CI if the monitor supports it.

Choose a power profile

Under Power profile, you can switch between the profiles available on your system. A power-saving profile extends battery life, a balanced profile suits everyday use and a performance profile prefers maximum performance. The available profiles depend on your system.

The selection is applied through the power profile service. If switching profiles is not possible, check that power-profiles-daemon is installed and running.
