Windows 10 has “Battery Use” screen that shows you what’s draining your laptop’s juice. That means it’ll tell you exactly what apps are using too much power.

This feature is part of the “Battery saver” screen in the Settings app.

Battery Use screen

This feature is relatively new to Windows 10, so you won’t find it anywhere in the old Control Panel. It’s located in the new Settings app, which you can launch by clicking or tapping the “Settings” option in the Start menu.

In the Settings app, select “System” and then select “Battery saver.” You can also just type “Battery saver” into the Cortana search box and select the “Battery saver” option to go directly to this screen.

On the right side of the screen, you’ll see an overview that displays how much battery life you have remaining, and how much time Windows estimates you’ll get from that. Click or tap the “Battery use” link under this heading to see more details.

Analyze your power usage

By default, the Battery Use screen will show information from the last 24 hours. However, you can also have it show information from the last 48 hours, or from the last week.

To change this setting, click or tap the dropdown box under “Showing battery use across all apps from the last” at the top of the screen and select “24 Hours,” “48 Hours,” or “1 Week.”

Below this box, you’ll see “System,” “Display,” and “Wi-Fi” percentages. This shows how much battery power has been used by system processes, the display, and your Wi-Fi radio.

You’ll probably see that the display is using quite a bit of power. To alleviate that, try lowering your screen’s brightness, or tell your display go to sleep more often in Settings > System > Power & Sleep.

The “In use” and “Background” options show how much power is used by applications while you’re using them, compared to applications running in the background.

If apps are using power in the background, you can click or tap the “Change background app settings” link and configure apps to not run in the background. This only works for universal Windows 10 apps. They won’t automatically receive notifications, fetch new data for live tiles, or perform other background tasks. This can help you save battery power, especially if you don’t actually use those new Windows 10 apps.

Scroll down further and you’ll see a list of applications. This is the most useful part of the list, as it lists your desktop applications as well as universal apps. It’ll display a list of the apps have have used battery power in that period, and show you what percentage of your battery power each app has used.

If an app doesn’t appear in the list here, you never used it while you were on battery, so it never consumed any battery power.

You can view more information about a specific application’s energy usage by clicking or tapping it and then selecting the “Details” button. You’ll be able to see how what percentage of power the app used for system processes, the display, and Wi-Fi. You’ll also be able to see how much power the app used while you were actively using it, and how much it used when running in the background.

As with the overview of all apps on the main screen, you can choose to view details for the last 24 hours, 48 hours, or one week. For example, here’s how much battery Google Chrome used on my laptop in the past 48 hours:

You may see the word “Allowed” beneath some Windows 10 universal apps in the list. This indicates they’re allowed to run in the background. You can select an app and then select the “Details” button to see more details. From here, you can disable the “Allow this app to run in the background” option and prevent the app from using power in the background.

Did this work? Lets hear in the comment section!
