Batteries power our favorite electronic devices, but they’re not meant to last forever. How to Check Laptop Health The good news is that Windows laptops have a battery report feature that breaks down whether your battery is still kicking or is on its last legs. All you need to do is enter one simple line of code.

The report will take the form of an HTML file saved onto your drive that will show you battery usage data, capacity history, and life estimates. If the battery needs to be replaced, this report will tell you, long before it has a chance to fail.
Generate Battery Report in Windows 10
For this task, you will need Windows PowerShell, a built-in command line tool you may have never used before. The easiest way to access it is to right-click on the Start icon and select Windows PowerShell (Admin) from the menu that appears. A pop-up window may ask for permission to make changes to your device; say yes.
The blue PowerShell command window will appear, allowing you to enter commands to automate certain tasks within Windows 10. Enter powercfg /batteryreport /output “C:\battery-report.html” into the window and press Enter to run the command. How to Check Laptop Health
PowerShell will then tell you the name of the generated battery life report HTML file and where it has been saved on your computer. In this case, it’s called battery-report.html and it has been saved to the C drive. You can now safely close PowerShell. How to Check Laptop Health
Open File Explorer and access the C drive. There you should find the battery life report saved as an HTML file. Double-click the file to open it in your default web browser.
The process works similarly in Windows 11. Right-click on the Start icon, but now you will select Windows Terminal (Admin) instead. Click Yes when the pop-up window asks for permission to make changes to your device.
This will open Windows Terminal, a tabbed terminal emulator that can run PowerShell, Command Prompt, and other command-line programs. PowerShell will be open by default, so enter powercfg /batteryreport /output “C:\battery-report.html” into the window and press Enter to run the command.
Once the command is entered, PowerShell will tell you the name of the generated battery life report and where it has been saved on your computer. You can see here that it’s named battery-report.html and is saved to the C drive. You can now close Windows Terminal.
Open File Explorer and click the OS (C:) entry under This PC. The battery report will be saved in this folder as an HTML file. Double-click to open the file in your default web browser.
The report will outline the health of your laptop battery, how well it has been doing, and how much longer it might last. At the top of the battery report, you will see basic information about your computer, followed by the battery’s specs.
