Windows 11 includes several performance and power management features designed to make computers run more efficiently. One of the most noticeable is Efficiency Mode, a feature that can reduce the resources used by certain apps and processes. While it can help improve battery life and keep background tasks under control, some users may want to turn it off when an application feels slower, less responsive, or restricted.
TLDR: Efficiency Mode in Windows 11 can be turned off through Task Manager by right-clicking a process and disabling Efficiency mode. It may also be managed indirectly through app settings, browser settings, power mode options, and startup app controls. If the option is greyed out, Windows may be managing a system process automatically. Turning it off can improve responsiveness, but it may increase battery use and CPU activity.
What Is Efficiency Mode in Windows 11?
Efficiency Mode is a Windows 11 feature that limits how much system power a process can use. It is designed to reduce pressure on the CPU, improve battery life on laptops, and keep background processes from interfering with active work. When a process is running in Efficiency Mode, Windows may lower its priority and use more energy-conscious scheduling.
This feature is most often seen in Task Manager, where certain processes display a small green leaf icon. That icon usually means Windows is treating the app or process as energy efficient. In many cases, this is useful. For example, a browser tab running in the background may not need full processing power. However, if an important application is placed into Efficiency Mode, it may seem sluggish or delayed.
Efficiency Mode is especially common with modern apps, web browsers, background services, and programs that Windows identifies as safe to throttle. Users who run video editing software, games, development tools, design applications, or large spreadsheets may prefer maximum responsiveness over power savings.
Why Someone Might Turn Off Efficiency Mode
Efficiency Mode is not harmful, but it is not always ideal. A user may want to disable it for several reasons, especially when performance is more important than battery life.
- Better app responsiveness: Some apps may respond more quickly when they are not being throttled.
- Improved performance during heavy tasks: Creative, technical, or gaming workloads may need full CPU access.
- Reduced delays: Background syncing, rendering, exporting, or compiling may finish faster.
- Troubleshooting: Turning it off can help determine whether Efficiency Mode is causing lag.
- Desktop usage: A plugged-in desktop computer may not need aggressive power saving.
However, users should understand the trade-off. Disabling Efficiency Mode can lead to higher power consumption, more heat, louder fans, and shorter battery life on laptops. For this reason, it is usually best to disable it only for apps where performance problems are noticeable.
How to Turn Off Efficiency Mode in Task Manager
The most direct way to turn off Efficiency Mode in Windows 11 is through Task Manager. This method works for many user-level apps and background processes.
- Right-click the Start button on the taskbar.
- Select Task Manager from the menu.
- If Task Manager opens in a simple view, select More details.
- Go to the Processes tab.
- Look for the app or process showing the green leaf icon or marked as running efficiently.
- Right-click the process.
- Select Efficiency mode to remove the check mark.
- Confirm the change if Windows asks for confirmation.
Once disabled, the process should no longer be limited by Efficiency Mode. If the green leaf icon disappears, the change has taken effect. If the process immediately returns to Efficiency Mode, the application itself or Windows may be reapplying the setting.
In some cases, a user may need to expand an app group in Task Manager. For example, browsers often contain multiple processes for tabs, extensions, graphics, and background services. The user may have to click the arrow beside the app name and disable Efficiency Mode for a specific process rather than the main app entry.
What to Do If Efficiency Mode Is Greyed Out
Sometimes the Efficiency mode option is visible but greyed out. This usually means Windows does not allow the user to change that specific process. It may be a protected system process, a required Windows service, or a process managed by the app itself.
If the option is greyed out, the user can try the following:
- Run Task Manager as administrator: Search for Task Manager, right-click it, and choose Run as administrator.
- Check a child process: Expand the app group and try disabling Efficiency Mode on an individual subprocess.
- Restart the app: Close and reopen the program, then check Task Manager again.
- Update the app: Some apps manage their own efficiency settings and may behave differently after updates.
- Leave system processes alone: If Windows protects the process, changing it may not be recommended.
It is important that users avoid forcing changes to unknown system processes. Windows uses background resource management to keep the system stable. Disabling restrictions on the wrong process may not improve performance and could create instability.
How to Turn Off Efficiency Mode for Microsoft Edge
Microsoft Edge has its own performance-saving features, including sleeping tabs and efficiency-related settings. Even if Efficiency Mode is disabled in Task Manager, Edge may still reduce resource usage through browser settings.
To adjust these settings, the user can follow these steps:
- Open Microsoft Edge.
- Select the three-dot menu in the upper-right corner.
- Choose Settings.
- Select System and performance.
- Look for options related to Efficiency mode, Sleeping tabs, or Save resources.
- Turn off the settings that reduce performance if maximum responsiveness is preferred.
Edge may enable efficiency features automatically when a laptop is unplugged or when battery is low. Users who want consistent performance should review these settings carefully. They may also choose to keep sleeping tabs on while disabling broader efficiency features, depending on how they use the browser.
How to Turn Off Similar Efficiency Features in Google Chrome
Google Chrome also includes performance and memory-saving features. While these are not exactly the same as Windows 11 Efficiency Mode, they can create similar results by reducing activity from inactive tabs.
To manage Chrome performance settings, a user can do the following:
- Open Google Chrome.
- Select the three-dot menu.
- Go to Settings.
- Select Performance.
- Review options such as Memory Saver and Energy Saver.
- Turn off the settings if they are affecting active work.
For users who keep many tabs open, these settings can be helpful. However, if web apps reload too often, video calls stutter, or browser-based tools slow down, disabling memory or energy saving may improve the experience.
Change Windows 11 Power Mode for Better Performance
Efficiency Mode is only one part of Windows 11 power management. The system’s overall Power Mode can also affect performance. A laptop set to maximum power savings may feel slower even when Efficiency Mode is disabled for a particular process.
To change Power Mode in Windows 11:
- Open Settings.
- Select System.
- Choose Power & battery.
- Find Power mode.
- Select Best performance for maximum speed, or Balanced for a mix of speed and battery life.
On desktop PCs, the setting may appear under Power rather than Power & battery. Choosing Best performance can reduce throttling and allow the computer to use more resources when needed. However, it may also increase heat and fan noise.
Disable Efficiency Mode for Startup Apps Indirectly
Some processes enter Efficiency Mode because they run quietly in the background after startup. If a user does not need these apps immediately, disabling them from startup may be better than trying to manage Efficiency Mode manually.
To manage startup apps:
- Open Task Manager.
- Select the Startup apps tab.
- Review the list of apps that launch automatically.
- Right-click unnecessary apps and choose Disable.
This does not turn off Efficiency Mode directly, but it reduces the number of background processes Windows must manage. Fewer startup apps can improve boot time, reduce CPU usage, and make the computer feel faster overall.
Should Efficiency Mode Be Turned Off Permanently?
For most users, Efficiency Mode should not be turned off everywhere. It is designed to help Windows 11 run smoothly, especially on laptops and lower-powered devices. When used properly, it can prevent background apps from consuming too many resources.
That said, performance-focused users may prefer to disable it for specific applications. For example, someone editing video, playing a demanding game, recording audio, or running a virtual machine may not want Windows to limit those processes. The best approach is usually selective disabling: leaving Efficiency Mode enabled for minor background tasks while turning it off for important workloads.
If a program repeatedly enters Efficiency Mode and performs poorly, the user should also check that program’s internal settings. Many modern applications include their own power-saving, background suspension, or performance modes.
Troubleshooting After Turning Off Efficiency Mode
If disabling Efficiency Mode does not improve performance, the cause may be elsewhere. Windows performance issues can come from limited memory, slow storage, outdated drivers, malware, overheating, or too many background apps.
Users can try these troubleshooting steps:
- Restart the computer: A restart can clear stuck processes and temporary issues.
- Update Windows: Updates often include performance and stability fixes.
- Update graphics and chipset drivers: Driver problems can cause lag in demanding apps.
- Check memory usage: If RAM is nearly full, apps may slow down regardless of Efficiency Mode.
- Scan for malware: Unwanted software can consume resources in the background.
- Check temperatures: Overheating can cause the CPU to throttle automatically.
Efficiency Mode is only one piece of the performance puzzle. If the computer remains slow, a broader system review may be necessary.
