Windows 10 has no default feature that instantly displays the detailed information about your laptop battery. There is a “Battery” item inside the Windows Settings but it displays no information about your battery. It only allows you to check which apps consume more battery and an option to enable the battery life feature. To check the information about the battery installed on your laptop, you can use the powercfg command on Command Prompt.
powercfg doesn’t instantly display the information about the installed battery, though. But you can use it to generate an HTML file in which the HTML file contains detailed information about the battery installed on your laptop such as the battery type, capacity, battery usage, life estimate, and so on.
To use the powerfcg command to generate a battery information file, run Command Prompt as administrator. Right-click Command Prompt on the start menu and select More -> Run as administrator.
Type the following command:
The command above will generate an HTML file — battery-report.html — under C:\WINDOWS\system32\. Simply open the file using your favorite web browser. As you can see, the file report consists of several sections. On the top section, the file tells you a brief into about your laptop. On the next section (Installed batteries), the file tells you about the battery installed on your system.
In order to make it easy for you to find the generated HTML report file, you can also set custom output when executing the powerfcg command about. The example below will generate the report file under the D:\ drive on your laptop.
powercfg /batteryreport /output "d:\battery_report_detail.html"
