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).
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 toprevent an app from running in the backgroundand 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.”

The Power Usage column lists each running app’s battery usage. It displays three values: Very High, High, and Low.
If an app is consuming too much battery power, but you aren’t using that app, close the app.If the app refuses to close, right-click it in Task Manager and choose “End Task.”

Get a Battery Usage Report With PowerShell
Windows 11’s built-in PowerShell utility allows you togenerate a battery health reportfor your machine. This report contains valuable information about your battery, like the installed batteries, battery usage, and more.

On the PowerShell window, type the following command (called acmdlet) 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.
Open File Explorer(press Windows+E), access the C drive, and double-click the “battery-report.html” file. The report will open inyour 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.
