POWERCFG: How To Check Battery Health Report And Energy Report In Windows Using CMD?

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 10, 8.1, 8, 7

On Windows 10 (and older versions) you can 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 which involves the use of Windows CMD to check battery health and generate Energy Report. You can also generate the Battery Health Report, which shows the charging cycles and performance of your battery over the course of time.

    Note: In later versions of Windows 10, the command prompt option is replaced by PowerShell in the Start button’s context menu. You can search for CMD in the Start Menu. Next, right-click CMD and click Run As Administrator.
  2. Type the command:
    powercfg/energy

    It’ll take 60 seconds to generate an energy report of your battery.

Generate Windows 10 Battery Report using POWERCFG command

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 10 battery report:

  1. Open CMD in Admin Mode as above.
  2. Type the command:
    powercfg /batteryreport

    Press Enter.
    powercfg-battery-report
  3. To view the Battery Report, press Windows+R and type the following location:
    C:\WINDOWS\system32\battery-report.html
    Click Ok. This file will open in your web browser.
    powercfg-battery-report-2

    powercfg-battery-usage

This data will refresh every time you type the POWERCFG commands in the CMD window 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.

Note: We have tested the above method for Windows 10, 8, 8.1. It will also be used to check battery health on Windows 7.
