How to Check Laptop Battery Health on Windows and Mac: A Step-by-Step Guide
Are you experiencing rapid battery drain on your laptop? Knowing how to check your laptop’s battery health is essential for maintaining optimal performance and ensuring longevity. This guide will provide you with a comprehensive, step-by-step approach to checking battery health on both Windows and Mac operating systems. You’ll learn how to generate a detailed battery report, assess your battery’s condition, and understand when it’s time for a replacement.
Before starting, make sure you have administrative access to your computer. For Windows users, you’ll be using the Command Prompt, and for Mac users, you’ll be checking system information. Ensure your laptop is charged and connected to power for the best results.
Step 1: Open Command Prompt as Administrator on Windows

cmdin the search bar. - Right-click on Command Prompt and select Run as administrator.
- If prompted, click Yes to allow changes.
Step 2: Generate the Battery Report
Once you have the Command Prompt open, you can generate a battery report to assess your battery health:
- In the Command Prompt, type the following command and press Enter:
powercfg /batteryreport - This will create a battery report file saved in your user folder.
Step 3: Locate and Open the Battery Report
The battery report is saved as an HTML file, which you can view in your web browser:

- Look for the file named battery-report.html. You can sort the files by name if necessary.
- Double-click on the battery-report.html file to open it in your default web browser.
Step 4: Analyze the Battery Report
Once the report is open, take note of several key metrics:
- Design Capacity: This is the original capacity of the battery when it was new.
- Full Charge Capacity: This indicates the current maximum charge your battery can hold. Ideally, this should be close to the design capacity.
- Cycle Count: This represents the number of complete charge cycles the battery has gone through. A high cycle count can indicate wear and tear.
Step 5: Checking Battery Health on Mac
If you’re using a Mac, you can check the battery’s health through the system settings:
- Click on the Apple menu in the top left corner.
- Select About This Mac and then System Report.
- Under the Power section, check the Cycle Count and Condition of the battery.
