Keeping track of your laptop’s battery health is important for ensuring it lasts as long as possible. Windows 11 provides a built-in way to generate a detailed battery report that helps you understand your battery’s performance over time.

This report gives clear insights into your battery’s capacity, usage patterns, and overall condition. Generating it is simple and doesn’t require any third-party software.

In this guide, you will learn how to create an accurate battery report step-by-step, so you can monitor your battery’s health effectively.

Whether you want to check if your battery needs replacement or just want to optimize usage, this report is a handy tool.

Quick Note Before You Begin

• Make sure your laptop is running Windows 11 and is fully updated.
• You need to have administrator privileges on your computer to generate the battery report.
• Close any unnecessary programs to avoid interference during report generation.
• It’s helpful to have your laptop charged to at least 50% for more accurate usage data.

Step 1: Open Command Prompt with Administrator Rights

To generate the battery report, you first need to access the Command Prompt with elevated permissions. This is important because the report requires system-level access to gather detailed battery information.

1. Click on the Start button or press the Windows key on your keyboard.
2. Type cmd or Command Prompt in the search bar.
3. Right-click on the Command Prompt app from the search results.
4. Select Run as administrator from the context menu.
5. If prompted by User Account Control (UAC), click Yes to allow.

This opens a black window where you can type commands directly to your system.

Step 2: Enter the Command to Generate the Battery Report

Next, you will run a specific command that tells Windows to collect battery data and save it as a report.

1. In the Command Prompt window, carefully type the following command exactly as shown:

powercfg /batteryreport /output "%USERPROFILE%Desktopbattery-report.html"

This command does three things:

• powercfg is the tool that manages power settings.
• /batteryreport tells Windows to create the battery report.
• /output "%USERPROFILE%Desktopbattery-report.html" saves the report as an HTML file on your desktop for easy access.

After typing the command, press Enter.

Step 3: Locate and Open the Battery Report

Once the command finishes running, you will see a message indicating the report’s saved location.

1. Minimize or close the Command Prompt window.
2. Go to your Desktop and look for a file named battery-report.html.
3. Double-click the file to open it in your default web browser.

The report will display detailed information about your battery’s usage history, capacity, and recent usage statistics.

Understanding the Battery Report

The battery report contains several sections that provide valuable insights:

• Installed Batteries: Shows information about your battery’s design capacity and full charge capacity.
• Recent Usage: Details about battery drains and charges over the last few days.
• Battery Usage: Graphs and stats showing how your battery has been used over time.
• Battery Capacity History: Shows how your battery’s full charge capacity has changed compared to the design capacity.
• Usage History: Records of system usage on battery and plugged-in states.

Reviewing these sections helps you determine if your battery health is declining and whether it needs replacement.

Alternative Method: Using Windows PowerShell

If you prefer PowerShell over Command Prompt, you can generate the report using the same command.

1. Open Windows PowerShell as an administrator by right-clicking the Start button and selecting Windows Terminal (Admin) or Windows PowerShell (Admin).
2. Type the following command and press Enter:

powercfg /batteryreport /output "$env:USERPROFILEDesktopbattery-report.html"

The report will be saved on the desktop just like before.

FAQs

How often should I generate a battery report?

It’s good to create a battery report every few months or if you notice reduced battery performance. This helps you track changes over time.

Can I generate a battery report on a desktop PC?

Battery reports are only relevant for devices with batteries, such as laptops, tablets, or hybrid devices. Desktops usually don’t have batteries.

What if the report shows my battery capacity is much lower than design capacity?

This means your battery is aging and not holding charge as well. You might consider replacing the battery if performance is significantly affected.

Is the battery report safe to share?

Yes, the report contains only system and battery usage data, not personal information.

Can I generate the report without administrator rights?

No, administrator privileges are required to access detailed battery information.

When Nothing Works

If you encounter errors or the battery report does not generate:

• Restart your computer and try the steps again.
• Ensure you are running Command Prompt or PowerShell as an administrator.
• Check for Windows updates and install any pending updates.
• Consult official Microsoft support pages for troubleshooting: Microsoft Support.

If your battery health is critical and the report shows poor results, consider contacting your device manufacturer for service options.

Conclusion

Generating a battery report in Windows 11 is a straightforward process that provides valuable insights into your laptop’s battery health and usage. By following the simple steps outlined above, you can quickly create a detailed report to monitor your battery’s condition and make informed decisions about its care.

Regularly checking your battery report helps extend your device’s lifespan and ensures you get the best performance possible. Remember, keeping your system updated and charged properly complements good battery maintenance.
