Checking Windows 11 laptop battery health can be important if you own a portable PC that’s running Microsoft’s latest OS.
Thankfully, looking into the state of your Windows 11 laptop battery health is fairly straightforward, and can be done in pretty much no time. All that’s really required is running a quick line of code through Windows’ Command Prompt, then saving the resulting battery report as an HTML file you can then open in your browser of choice.
Once said report is in front of you, it’s easy to instantly analyze everything including the type of battery installed in your laptop, recent battery usage, battery usage history, battery capacity history and battery life estimates. And yes, that’s definitely the most times we’ve ever typed ‘battery’ in a single sentence here at Tom’s Guide.
While these figures may appear to be a little daunting at first, they’re useful for letting you know if there’s anything untoward going on with your laptop’s battery. If you find that historical usage is showing that your battery is consistently losing juice, you may need to replace your laptop battery.
For now, though, let’s not worry about the worst case scenario. Instead, we’ll focus on running you through the steps of how to check the battery health of your Windows 11 laptop, with our quick and easy to follow guide.

After the ‘Best match’ menu pops up, right click on the Command Prompt app and click ‘Run as administrator’.
3. Type powercfg /batteryreport /output “C:\battery_report.html” and press enter

After clicking this html link, your battery report will open in your default browser. From here you can check everything from ‘Usage history’, ‘Battery capacity history’, to ‘Battery life estimates’.
And there you have it. You now know how to quickly check the battery health of your Windows 11 laptop. This obviously isn’t a process you’re going to have to regularly run through if your laptop is relatively new, but for older models, it’s probably worth checking on your battery health every few months.
