Windows 10 (and previous versions) have a built-in tool to find everything about the battery installed on your laptop. Yes, if you are hearing about this for the first time then you are not alone. With Windows, Microsoft seems to have built a feature that lets you check every important detail about the battery installed on your laptop. Interestingly, Windows has been tracking the health of your laptop’s battery from the day it was installed.
It is not only an interesting tool but also one that can come handy when you want to replace the battery on your PC. All you need to do to find out about your laptop’s battery is run two lines of commands on command prompt. Yes, it is that simple and the tool immediately flushes out a report in HTML format. The report details information such as the number of cycles that you have used on your laptop’s battery and how it has been used in the past three days.
Windows 10 built-in battery report tool: what is it?
I alternate between a Windows laptop and a Chromebook for work. Whenever I need to do tasks on the browser, I use my Chromebook exclusively. However, when I need to do things like edit an image or have multiple web browser tabs or run a test like this, I immediately switch to my Windows machine. This built-in battery life tool gave me a clear idea about when I switch to my Chromebook exclusively by just looking at the idle time of the laptop’s battery.
How to check computer battery health in Windows 10
- Open Command Prompt on your Windows 10 machine. Use Windows Button + X and select
- Command Prompt (Admin) or search for Command Prompt.
- Now, you can set the path to the desktop so that the report is easy to find.
- Type cd %HOMEPATH%/Desktop
- Once the path is set, type powercfg /batteryreport
This command will run the powerconfig tool and will result in a battery report. The report should now be on the desktop as an HTML file. You can double click on the file to open it in your browser. For some users, you might see a prompt asking which program you want to use to open the HTML file. Select the browser installed on your PC. Now, you will see every minutiae of detail about the battery installed on your computer.
The report will first show the name of your computer including details about the Windows version and design capacity as well as full charge capacity of your laptop’s battery. Then the report dives into juicy bits of information including recent usage and usage history. In the battery usage chart, you can see how the battery drop slows for a period, thus highlighting the period when I must have switched to another machine. For most Windows 10 users, the data that will come handy is the battery life estimates.
This shows how long you can expect the battery to last based on your actual usage. You can even see how this estimate has changed since the time of the first Windows installation. We need to note that this battery report only runs from the time of installation of the OS. So, if you reset your machine with a new installation then it won’t be showing full history. In a nutshell, this is a great tool to dig into your laptop’s battery where you are an amateur or a pro about computers.
