How to check the health of a laptop battery; One of our constant worries about laptops is their batteries. Usually, when the battery is weak we notice a decrease in its performance; But in Windows 10 we can get a full report of battery conditions.
How to check the health of a laptop battery
Batteries turn on our favorite electronic devices; Unfortunately, this can be bypassed-but not unless you’re a techie who knows what he’s doing. The good news is that Windows 10 laptops have a battery report feature that shows you if you still have hope for a laptop battery. To view battery information, you can easily create an HTML file with battery usage data, capacity history, life expectancy, and other important battery information based on your usage. This report will notify you before the current battery fails to replace battery or purchase a new laptop.
Create battery reports in PowerShell
Battery reporting is generated via Windows PowerShell, a command-line tool you may have never used before. The easiest way to access PowerShell is to right-click on the Windows or Start icon and click on Windows PowerShell (Admin) from the menu that appears.
This may cause a pop-up window to request changes to your device. Click Yes to confirm. Another way to access PowerShell is to look for it in the Start menu. Once found, right-click on it and select Run as administrator. After the pop-up window appears, click the Yes button to allow the changes.
The PowerShell blue command window will appear, allowing you to enter your commands to automate specific tasks in Windows 10. Enter the command powercfg / batteryreport / output “C: \ battery-report.html and press Enter to run.
After this, PowerShell will tell you the name of the HTML file of the created battery life report and its storage on the computer. In this case, the file name is battery-report.html and its storage location is drive C. You can now close the PowerShell window.
View battery report
Open File Explorer and go to drive C. Here you should find the HTML battery life report. When the file is found, double-click it to open it in the default browser.
This report shows the health of the laptop battery. At the top of the battery report, you will see basic information about the computer and then the battery specifications.
All battery discharges during the last three days have been tracked in the Battery usage section. Note in the Recent usage section when the laptop was running on battery power and when it was connected to AC. You can see the full history of battery usage in the Usage History section.
The Battery capacity history section shows how the battery capacity has changed over time. On the right is the capacity, which shows the basic condition of the battery. On the left, you can see the full charge capacity of the laptop battery, which has probably decreased over time and with more use of the device.
The Battery life estimates section shows the battery discharge time. The left shows the actual battery life and the right shows the factory value of battery life. The computer, for example, was charged at 6:02:03 in design or factory capacity; But for now, 4:52:44 lasts.
Many new laptops show a full charge capacity slightly higher than the design capacity; But as the battery ages, the full charge capacity decreases. If the full charge capacity is 20% less than the original design capacity, it means that the battery is old and needs to be replaced. The batteries of modern laptops will stop long before the full charge capacity reaches zero.
This report is not complete and is estimated based on how the battery has been used in the past. This estimate may be skewed if you change the way you use your computer in the future, or even make a minor change, such as changing your browser.
