On laptops and tablets, battery life is critical as it will determine how long Windows 11 will run with your apps. Therefore, understanding the health of the battery can be helpful in discovering any power issues or if the battery needs to be replaced.
Whatever the reason, Windows 11 includes a command-line tool that analyzes usage over time to generate a battery health report to examine battery specifications, power consumption , estimated battery life and details to determine if the device needs a battery replacement. .
In this Windows 11 guide, we’ll walk you through the steps to create and understand your laptop or tablet’s battery status report.
How to Check Battery Status on Windows 11
To create a battery health report in Windows 11, follow these steps:
- To open To start up.
- To research Command Promptright-click on the first result and select the Execute as administrator option.
- Type the following command to create a battery report on Windows 11 and press Walk in:
powercfg /batteryreport /output "C:battery_report.html"
After completing the steps, the report will be automatically saved in the main installation drive.
Reading the battery report
- To open File Explorer.
- Click on This PC from the left pane.
- In the “Devices and drives” section, double-click the “C” drive.
- Double-click to open the “battery_report.html” file with the default web browser.
The report is made up of several sections with self-explanatory information. Perhaps the section with the most information you want is the “Batteries Installed” section which gives you a general overview of the battery installed in your computer, including name, manufacturer, serial number, chemistry , the design capacity and the number of cycles.
If you want to know if the battery needs to be replaced, you need to look at the “design capacity” and the “full charge capacity”. In the example you can see that the battery was designed to hold 44156 mWh and the total charge capacity is 44156 mWh, indicating that the battery can still hold 100% charge. However, if the full charge capacity decreases significantly (approximately less than 50%), this could indicate that it is time to replace the battery.
The “Recent Use” section shows when the computer was active, suspended, or connected to standby. This information can be useful in determining if the device automatically wakes up at random times when it shouldn’t.
The “Battery Usage” section displays a graph with valuable information about battery drain over the past three days.
“Usage History” shows how long the computer has used the battery and when it was plugged into an electrical outlet.
The battery capacity history tracks the battery charge capacity history.
Finally, the “Battery Life Estimates” shows the battery life based on the observed consumptions. In other words, this section shows a prediction of battery life for common use.
The tool works better because it collects more data over time. This means that if you’re generating a battery report on a new device or install, you probably won’t find many useful details. If you are having issues with the battery, it is recommended that you go through several cycles to find patterns that might help determine the problem.
