How to Generate a Battery Health Report on Windows 11

Creating a battery health report in Windows 11 can help you understand how efficiently your laptop’s battery is functioning and track its usage over time. This is especially helpful if you’ve noticed a decline in battery performance and want to analyze any capacity changes. This guide will walk you through the steps to create this report using Windows 11’s built-in tools.

Step 1: Open Command Prompt

The first step is to launch the Command Prompt with administrative privileges:

• Press Win + S and type "Command Prompt" or "CMD".
• Select Run as Administrator.

Step 2: Run the Battery Report Command

In the Command Prompt, enter the following command:

powercfg /batteryreport /output "C:\battery-report.html"

This command uses the powercfg utility to generate a battery report and saves it as an HTML file at the specified path. In this example, the file will be saved in the root of the C: drive as battery-report.html.

Step 3: Access the Battery Report

After running the command, open File Explorer and navigate to C:\battery-report.html. Open the file in any browser to view the report.

What’s in the Report?

The battery report contains several sections, including:

• Installed Batteries: information about your battery, such as manufacturer, design capacity, and unique ID.
• Recent Usage: recent battery activity, including charging and discharging states.
• Battery Usage: a chart showing battery consumption over a set period.
• Battery Capacity History: a history of the battery capacity in milliwatt-hours (mWh) compared to its original capacity.
• Battery Life Estimates: estimated battery life based on current capacity data.
