In the Windows environment, you can generate a detailed battery report using the Command Prompt (CMD). This report provides insights into your battery's health, usage history, and other important metrics. This is particularly useful for laptop users who want to monitor their battery's performance over time.

Examples:

1. Open Command Prompt as Administrator:

   • Press Windows + X and select "Windows Terminal (Admin)" or "Command Prompt (Admin)" from the menu. This will open the Command Prompt with administrative privileges.

2. Generate the Battery Report:

   • In the Command Prompt window, type the following command and press Enter:

     powercfg /batteryreport /output "C:\battery_report.html"

   • This command will create a battery report and save it as an HTML file at the specified location (C:\battery_report.html).

3. Access the Battery Report:

   • Navigate to the location where the report was saved (in this case, C:) using File Explorer.
   • Open the battery_report.html file in your preferred web browser to view the detailed battery information.

The battery report includes various sections such as:

• Installed Batteries: Information about the battery, including name, manufacturer, chemistry, and design capacity.
• Recent Usage: A log of the battery's usage over the last few days.
• Battery Usage: Graphical representation of the battery's usage.
• Usage History: Detailed history of battery usage and charge levels.
• Battery Capacity History: Information on how the battery's capacity has changed over time.
• Battery Life Estimates: Estimates of battery life based on observed drains.

These insights can help you understand how your battery's performance is changing and when it might be time to consider a replacement.
