Learn how to check Windows 11 laptop battery health with our easy to follow guide
Checking Windows 11 laptop battery health can be important if you own a portable PC that’s running Microsoft’s latest OS.
Battery life is obviously a big deal, whether you’re working on one of the best business laptops or enjoying a marathon Starfield session on one of the best gaming laptops currently on the market.
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.
