Check Laptop Battery health on Windows

To check laptop battery health on Windows, use the Command Prompt by typing powercfg /batteryreport and pressing Enter, then navigate to the generated HTML file to view design capacity versus current full charge capacity; a significantly lower current capacity indicates poor battery health. Alternatively, access the BIOS/UEFI settings during startup and look for a battery health option under the general or overview section. Method 1: Using the Command Prompt (Windows) 1. Open Command Prompt: Click the Start button and type cmd in the search bar, then right-click on Command Prompt and select Run as administrator. 2. Generate the Battery Report: In the Command Prompt window, type the command powercfg /batteryreport and press Enter. 3. Locate the Report: A message will appear indicating the location of the battery report file, usually C:\Users\[YourUserName]\battery-report.html. 4. View the Report: Open File Explorer, go to your user folder, and then open the generated HTML file to view your battery's design capacity and full charge capacity. 5. Check Battery Health: Compare the Full Charge Capacity with the Design Capacity. A significant difference, where the full charge capacity is much lower than the design capacity, indicates a worn-out battery.
