How to Check Laptop Battery Capacity in Windows 10

If you want to monitor your laptop's battery health and capacity in Windows 10, there are a few simple methods that don’t require installing additional software. This can be helpful for checking battery wear or assessing its current performance. Here’s a step-by-step guide to checking your battery capacity:

1. Open Command Prompt

First, open the Command Prompt with administrator rights:

• Press Win + X or right-click the "Start" button.
• Select “Command Prompt (Admin)” or “Windows PowerShell (Admin)”.

2. Enter the Command to Generate a Battery Report

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

powercfg /batteryreport

This command generates a battery report and saves it as an HTML file on your computer. By default, it’s saved in C:\Users\YourUsername\battery-report.html.

3. Open the Battery Report

Go to the specified path and open the battery-report.html file in any web browser. This report provides detailed information about your battery’s condition, including:

• Design Capacity – the original battery capacity when it was new.
• Full Charge Capacity – the current maximum capacity the battery can hold.
• Battery Life Estimates – estimated battery life based on the current state.

4. Interpreting the Data

Compare the Design Capacity and Full Charge Capacity values. A significant difference between the two indicates that the battery has lost some capacity over time and may need replacement. Battery Life Estimates will also help you gauge how long your battery can last under current conditions.
