How to Generate a Battery Report

On Windows 10 & 11

1. Click the Start Menu and type cmd.
2. Right-click on **"Command Prompt"** and select **"Run as administrator"**.
3. In the black window that appears, type this exact command: powercfg /batteryreport
4. Press **Enter**.
5. It will save a file. You can find it at the path it shows, usually: C:\Windows\system32\battery-report.html
6. Open that file (it will open in your web browser).
7. Screenshot the top section titled **"Installed batteries"**. We need to see the **"Design Capacity"** and **"Full Charge Capacity"**.

On macOS (MacBooks & iMacs)

1. **Hold down the `Option` key** on your keyboard.
2. While holding `Option`, click the **Apple icon** () in the top-left corner.
3. Click **"System Information..."** (it will be the first item).
4. A new window will open. On the left side, under the "Hardware" section, click **"Power"**.
5. Take a screenshot of this "Power" screen. We need to see the **"Health Information"** section, which shows the **"Cycle Count"** and **"Condition"**.
