If your Windows 10 is slow, this feature will improve it for you. Therefore, I will guide you to turn on Eco Mode power saving mode on Windows 10 in this article.
What is Eco Mode on Windows 10?
Eco Mode is an experimental feature on Windows 10, aimed at improving battery life and temperature on laptops. It limits resource-hogging applications and processes in the background. You only have 1 browser tab turned on, but the computer heats up, the fan starts spinning, and the computer shows signs of lag. This happens mainly because apps running in the background eat up resources unnecessarily.
Therefore, Microsoft wants to provide users with the feature to limit resources in any application they want, be it system applications or third-party applications. This feature is integrated into Task Manager, allowing users to find and set other applications to Eco mode.
Eco Mode works by lowering a task’s process priority in a new framework called EcoQoS, giving the CPU a breather. This framework improves the responsiveness of active tasks, reduces fan noise and thermal regulation, and improves battery life. Framework is only used for CPU at this time.
Microsoft is asking programmers to set Eco mode as default in their applications. The good news is that Microsoft Edge and Google Chrome already use the same method that EcoQoS uses. That’s why Task Manager does not allow you to enable Eco mode on these browsers.

While Eco mode is a great additional feature, there is a possibility that Windows 10 may accidentally set an active application to Eco mode. For example, if you’re using photo editing software, you wouldn’t want Windows 10 to place system resource restrictions on that software. In such cases, you can open Task Manager and turn off Eco mode for that task. This way, you will be able to take full advantage of your PC’s resources.
