View Battery Usage History With Settings

Windows 11’s built-in Settings app allows you to view the battery usage history of your installed apps. This way you can see what app has used the most amount of battery power.

To do that, open Settings using Windows+i. From the left sidebar, select “System.” On the right pane, choose “Power & Battery.”

"System" and "Power & Battery" highlighted in Settings.

In the Battery section, choose “Battery Usage.” In the open graph’s top-right corner, click the drop-down menu and select “Last 24 Hours” or “Last 7 Days” (depending on what you want to see).

"Battery Levels" options highlighted in Settings.

In the Battery Usage Per App section, you’ll see each installed app’s battery usage. Next to each app, you’ll see the battery usage in percentage. Beneath each app, you will find the app’s current as well as background battery usage.

If you’d like to sort the apps, in the top-right corner, click the “Sort By” drop-down menu and choose Overall Usage, In Use, Background, or Name.

If you want to prevent an app from running in the background and consuming the battery power, next to that app on the list, click the three dots and choose “Manage Background Activity.” On the open page, select the “Let This App Run in the Background” drop-down menu and choose “Never.”

If you don’t use an app anymore on your PC, it’s a good idea to get rid of it so that it never consumes your battery power. To do that, head into Settings > Apps > Installed Apps. Next to an unused app, click the three dots and choose “Uninstall.” Select “Uninstall” in the prompt.

Get a Battery Usage Report With PowerShell

Windows 11’s built-in PowerShell utility allows you to generate a battery health report for your machine. This report contains valuable information about your battery, like the installed batteries, battery usage, and more.

To get that report, launch Windows Search (press Windows+S), type PowerShell, and choose “Run as Administrator.” Select “Yes” in the User Account Control prompt.

"Run as Administrator" highlighted for PowerShell in Windows Search.

On the PowerShell window, type the following command (called a cmdlet) and press Enter. This cmdlet generates a battery report with the name battery-report.html and saves it in the C drive’s root folder.

powercfg /batteryreport /output "C:battery-report.html"

The cmdlet to generate a battery report typed in PowerShell.

Open File Explorer (press Windows+E), access the C drive, and double-click the “battery-report.html” file. The report will open in your default web browser. As you can see, the report is divided into multiple sections, with each section being self-explanatory and giving you details about your device’s battery.
