Keeping your Windows 11 device energy-efficient is important for extending battery life and reducing power consumption. Many applications can use more energy than necessary, impacting your device’s performance and battery health. Monitoring and reducing application energy usage helps maintain a smooth computing experience while saving power.

This guide will walk you through simple steps to check which apps consume the most energy and how to manage them effectively. Whether you’re using a laptop or desktop, these methods can help you optimize your system’s energy use without complicated tools.

You don’t need to be a tech expert to follow these instructions. Each step is broken down clearly so anyone can improve their device’s energy efficiency.

Let’s get started with the basic checks and tools built into Windows 11 that make energy monitoring easy and accessible.

Quick Note: What You Need Before You Begin

• Windows 11 Operating System: These instructions are specific to Windows 11. Make sure your device is running this version.
• Basic User Access: You should be able to open Settings and Task Manager on your computer.
• Charging or Battery: For laptops, ensure your battery is charged or plugged in for accurate readings.
• Patience: Some methods take time to show energy usage trends, so allow a few minutes when monitoring.

Step 1: Check Energy Usage Using Task Manager

The Task Manager is the easiest way to see which applications are using the most energy right now. It shows real-time data and helps identify apps that drain your battery.

1. Open Task Manager: Press Ctrl + Shift + Esc or right-click the Start button and select Task Manager.
2. Switch to More Details: If Task Manager opens in a simple view, click More details at the bottom to see all tabs.
3. Go to the Processes Tab: Here, you’ll find a list of running applications and background processes.
4. Locate the Energy Usage Column: Scroll right to find the Energy usage and Energy usage trend columns.
5. Review the Energy Use: Apps show statuses like Very low, Moderate, or High. This lets you identify energy-hungry apps instantly.

Why this matters: Identifying high energy usage apps helps you decide which ones to close or manage to save power.

Step 2: Manage Startup Apps to Reduce Energy Drain

Many apps start automatically when you turn on your PC. Some are not needed immediately and run in the background, consuming energy unnecessarily.

1. Open Settings: Click the Start menu and select Settings (gear icon).
2. Go to Apps > Startup: This section lists all apps configured to start automatically.
3. Review the List: Check the Startup impact column, which shows how much energy the app uses at startup.
4. Disable Unnecessary Apps: Toggle off apps you don’t need right away. For example, apps like Skype or Spotify can be started manually when needed.

Why this matters: Reducing startup apps lowers initial energy use and can speed up your PC’s boot time.

Step 3: Use Battery Settings to Monitor App Usage

Windows 11 offers a detailed battery usage view, showing energy consumption over time by each app.

1. Open Settings: Press Win + I or click the Start menu and select Settings.
2. Navigate to System > Power & Battery: This section contains power-related settings and battery usage data.
3. Scroll to Battery Usage: Click on Battery usage by app to see a detailed breakdown.
4. Analyze the List: You can see which apps use the most battery over the past 24 hours or 7 days.
5. Make Changes: If an app is consuming too much battery, consider updating it, closing it when not in use, or replacing it with a lighter alternative.

Why this matters: This feature helps you understand long-term energy trends rather than just momentary spikes.

Step 4: Adjust Power Mode for Energy Savings

Windows 11 includes different power modes to balance performance and energy usage.

1. Open Settings: Go to System > Power & Battery.
2. Locate Power Mode: Under the Power section, find the dropdown menu labeled Power mode.
3. Select a Power Saving Mode: Choose Best power efficiency to reduce energy consumption, especially useful on battery-powered devices.

Why this matters: Lower power modes reduce background activity and limit app performance to extend battery life.

Alternative Methods and Advanced Options

For users comfortable with more detailed controls, Windows 11 also offers additional tools:

• Windows Performance Analyzer: A tool for advanced users to analyze system and app energy usage deeply.
• Powercfg Command: Use the Command Prompt to generate detailed energy reports by typing powercfg /energy.
• Third-Party Apps: Some apps like BatteryInfoView or HWMonitor provide more detailed battery and energy stats.

These options are useful for troubleshooting or in-depth energy management but are not necessary for everyday users.

Frequently Asked Questions (FAQs)

How often should I check my app’s energy usage?

It’s a good idea to check energy usage weekly or whenever you notice your battery draining faster than usual.

Can closing apps really save battery on Windows 11?

Yes, closing apps that run in the background can reduce CPU and memory usage, which in turn saves battery.

Will disabling startup apps affect my computer’s performance?

Disabling unnecessary startup apps can improve boot times and reduce energy use without negatively impacting performance.

Is using Best power efficiency mode slower?

It can reduce performance slightly because it limits background activity and lowers CPU speed to save power.

Can Windows updates affect energy consumption?

Yes, some updates improve energy efficiency, while others may temporarily increase usage during installation.

When Nothing Works

If you continue to experience high energy usage despite following these steps, you may want to try the following:

• Update Windows: Ensure your system has the latest updates, as Microsoft often releases energy-saving improvements.
• Update Drivers: Outdated drivers can cause excessive energy use. Use Device Manager or manufacturer websites to get the latest versions.
• Scan for Malware: Malicious software can cause unusual CPU and energy usage. Run a full system scan using Windows Defender or other antivirus tools.
• Consult Official Resources: Visit the Microsoft Support site for more help.

Conclusion

Monitoring and reducing application energy usage on Windows 11 is straightforward using built-in tools like Task Manager and Battery settings. By regularly checking which apps consume the most energy, managing startup programs, and adjusting your power mode, you can extend your device’s battery life and improve overall efficiency.

Remember to keep your system updated and be mindful of apps running in the background. With these simple steps, you can enjoy a longer-lasting and more energy-efficient Windows 11 experience.
