To check the battery health of your Windows 11 laptop, you can generate a full battery report using the Windows Terminal app.
Navigate to Windows Terminal via the Windows 11 search, right-click, and select Run as administrator.
In Windows Terminal, run the command 'powercfg /batteryreport /output "C:\battery-report.html"' to generate the battery health report.
The report will be saved in HTML format at the specified destination, such as 'C:\battery-report.html'.
You can view the battery life report by opening the generated HTML file in a web browser.
The report includes details like Computer Name, BIOS, OS Build, Report Time, battery specifications, recent usage, battery capacity history, and battery life estimates.
Check the Full Charge Capacity to understand your battery's current capacity on full charge, which may decline with time.
The Battery Life Estimates section provides insights into how long the battery should last based on design capacity and how long it actually lasts.
This method helps you determine if your device's battery needs replacement based on its health and capacity.
