How to Run Apps Smoothly with Efficiency Mode in Windows

Many apps have high CPU use. To avoid excessive CPU utilization, users frequently use the Task Manager to close the applications involved in the problem. It is not, however, the most significant or long-lasting remedy. Thus, to solve this issue. Windows offers Efficiency Mode in Task Manager. In this post, we will share how you can run apps smoothly with efficiency mode in Windows.

What is Efficiency Mode in Windows?

It aims to lessen CPU load, cut fan noise, enhance thermal performance, and provide longer battery life. It was first included in Windows 10 and was formerly known as Eco Mode. Microsoft has introduced Efficiency Mode with the updated Task Manager and made significant adjustments. Additionally, it aids in locating the active apps in Task Manager. Read on to find out more about Efficiency Mode on Windows.

How to Run Apps Smoothly with Efficiency Mode in Windows

You can enable Efficiency Mode on your Windows 11 PC to ensure that apps run smoothly without wasting too much power and resources.

  1. Enable Efficiency Mode
  2. How Does Efficiency Mode Work?
  3. How Does It Help With System Performance and Battery Life

This feature is available to all users on a Windows PC.

1] Enable Efficiency Mode

  • Type Task Manager into the Windows search bar and click on the result to open Task Manager. Press the Ctrl + Shift + Esc keys to open Task Manager.
  • Find the software using most of your CPU resources next. To find out which app uses the most CPU, click the CPU label and arrange the apps in ascending order. You can also click the > button to expand the sub-processes if you want to enable it on a sub-process.
  • You can select the Efficiency Mode from the top of your screen or the context menu when you right-click a specific task. You may notice that the Efficiency Mode might already be enabled by default for some applications like Microsoft Edge, Chrome, etc.
  • A confirmation window will warn that the change might make some processes unstable. Click Turn on Efficiency Mode to enable Efficiency Mode for the chosen process.
  • A leaf-shaped icon for that process will appear once Efficiency Mode has been enabled.

Note: If Efficiency Mode is deactivated on a core process, you should not enable It because it could harm your system. Efficiency mode cannot be enabled for system processes or applications as these are protected system processes.

2] How Does Efficiency Mode Work?

Efficiency mode essentially prevents background operations from interfering with user-active foreground tasks. It accomplishes this by completing the following two things:

  • First, the Efficiency mode decreases the process priority of background tasks so that Windows will not provide these apps with essential resources.
  • Second, it implements EcoQoS, a Quality of Service package that slows the clock speed for productive tasks.

For instance, to run background services like indexing, updaters, scheduled jobs, sync engines, etc., you do not always need to run the CPU at a high clock speed. Developers can use the PowerThrottling API to inform systems that they can apply EcoQoS to this thread, leading to longer battery life and decreased thermal throttling and noise.

In conclusion, Microsoft’s newest method to extend battery life is Efficiency mode in Windows 11, which lowers the priority of processes or activities and clock speeds for background activities.

3] How Does It Help With System Performance and Battery Life

The purpose of Efficiency Mode is to increase battery life. By using fewer resources, it reduces electricity consumption. Efficiency Mode modifies specific tab activities on tabs you are not using and puts background tabs not being used after five minutes or less to sleep.

You can also use it to find OS-friendly apps already operating in Efficiency mode. Giving power users control over how many resources a process uses will support Microsoft’s Sustainable Software effort.

At a high level, the Task Manager Efficiency mode controls the number of resources processes use by lowering their priority and ensuring that they utilize EcoQoS to function effectively on the CPU.

If a user wants to know how well the system performs, Task Manager is the go-to utility program. To execute the work from the processes as effectively as possible and minimize their interference with the foreground experience.

Efficiency Mode offers users a mechanism to limit resource allocation per-process basis (in addition to just terminating a process since it could result in undesirable consequences).


Efficiency Mode in Windows in Windows is another attempt by Windows Team to control resource usage, but there are instances where the application freeze after coming back from standby.

It would help if you chose what works best for you because specific applications may not show noticeable performance changes. Depending on how it is implemented, the decrease in resource and process consumption may allow the battery of our device to last for hours longer.
