The Windows operating systems power save mode feature helps save energy or save power on devices. When the power save mode is activated, the operating system reduces the amount of power consumed by the device by limiting the performance of certain components. This includes reducing the display brightness, slowing down the processor speed, and turning off background apps and other power-intensive features.

Although the power saving mode is useful there are instances when you really don’t need it. A few examples are as follows:

  • Plugged-in devices: If your device is connected to a power source, such as a wall outlet, then power save mode may not be necessary.
  • High-performance tasks: If you’re performing high-performance tasks such as gaming, video editing, or running resource-intensive applications, power save mode may limit the device’s performance and result in reduced productivity.
  • Power source availability: If you know that you’ll have access to a power source soon, such as when you’re traveling or working in a location with available outlets, you may not need to use power save mode.
