Check Battery Health And Energy Report In Windows using POWERCFG

The laptops and netbooks we see today in the market would have been possible, or at least portable, without the existence of batteries. You can’t stop the battery decay process because it’s a natural phenomenon, but you can check battery health on your laptop from time to time. Thus, you can purchase a new battery at the right time before the current one becomes unusable.

If we set aside MacBooks, a standard Windows notebook comes with a battery backup of around 6 to 7 hours on average. You may get up to 10 hours of backup on some higher-priced portable computers.

However, these batteries, mostly lithium-ion type, decrease in charging capacity over time. It is entirely possible that a new laptop that can run for 6 hours on battery power may provide only 2 hours of juice after a couple of years of usage.

Laptop battery test in Windows 11, 10, 8.1, 8, 7

On Windows 11/10 (and older versions), you can get a detailed view of battery-related data like its original specifications, designed capacity, current capacity, etc. It also maintains updated information about battery usage sessions. A command-line utility known as POWERCFG allows you to access this data in a well-organized manner.

So, here is a method that involves using Windows CMD to check battery health and generate an Energy Report. You can also generate the Battery Health Report, which shows your battery’s charging cycles and performance over the course of time.

Check battery health and generate Energy Report In Windows using POWERCFG command

The energy report in Windows 10 can explain how much its capacity has reduced over time and any errors or wrongly configured settings that hurt the battery life. You can follow these steps to perform a laptop battery life test:

1. Right-click the Start button. Click Command Prompt (Admin).
   Note: In later versions of Windows 10, the command prompt option is replaced by Windows Terminal or PowerShell in the Start button’s context menu. You can search for CMD in the Start Menu. Next, right-click Command Prompt and click Run As Administrator.
2. Type the command:
   It’ll take 60 seconds to generate an energy report of your battery.
   
3. To access the energy report, press Windows key + R and type the location:
   C:\WINDOWS\system32\energy-report.html
   Click Ok. This file will open in your web browser.
   
4. Battery Capacity:

How to check battery health report using CMD

The battery report looks less geeky and includes information about day-to-day battery usage. It displays the recent usage stats and graph for the past three days, battery usage history of how many hours the system was active per week, and per week battery capacity history to give an idea of how much it has depleted in comparison to the original capacity.

On the basis of observed drains, the laptop battery test report also includes estimated numbers on how long the battery will last. Follow the steps mentioned below to generate your Windows 11/10 battery report:

1. Open CMD in Admin Mode as above.
2. Type the command:
   Press Enter.
   
3. To view the Battery Report, press Windows key + R and type the following location:
   C:\WINDOWS\system32\battery-report.html
   Click Ok. This file will open in your web browser.
   
   

How to check battery health report using PoweShell

2. When the terminal appears, type the following command

powercfg /batteryreport

3. Press Enter.

4. Now, PowerShell will generate a battery report for your PC. Press Windows key + R and type paste the following path:
C:\WINDOWS\system32\battery-report.html

5. Finally, Press OK.

This data will refresh every time you type the POWERCFG commands to check battery health, including the existing versions of the energy report and battery report.

You can regularly monitor your Windows battery health using the above powercfg command. For instance, it lets you keep an eye on the recent as well as long-term usage history of your battery. Among other things, the Windows 10 battery report gives battery life estimates that you can get after a full charge. This can be pretty helpful at times when you have a crunch of power supply.
