Windows 11 shows which apps are associated with recent battery use in Settings > System > Power & battery > Battery usage. You can review the last 24 hours or seven days, sort by overall, foreground, or background activity, and then decide whether an app needs to be closed, limited, repaired, updated, or removed. The percentages are Windows’ attribution for the selected period—not a laboratory measurement of that app’s exact electrical consumption.
Before you begin
- Use a Windows 11 laptop or tablet with an installed battery.
- Allow the device to accumulate recent battery activity; a new or recently reset installation may show little data.
- Expect wording and layout to vary by Windows 11 release, device firmware, and app type. The Battery usage section may be collapsed or positioned near the battery graph.
The walkthrough documented by HTMD was published on March 29, 2024. Its route and categories remain useful, but they should not be treated as pixel-identical instructions for every 2026 Windows 11 build. See the original walkthrough at HTMD.

How to check battery usage by app
- Press Windows + I to open Settings.
- Select System.
- Select Power & battery.
- Expand or open Battery usage.
- Choose Last 24 hours or Last 7 days.
- Scroll to the application list.
If you cannot find the page, search Settings for Battery usage. On some builds the graph and app list are presented together, while on others the list is behind an expansion control.

Last 7 days
Use the longer view to identify recurring behavior. It is usually more representative of normal work because one unusually heavy session has less influence.
Compare more than one period before changing settings. A high result is meaningful only in the context of how long the app ran and what it was doing.
Understand the battery graph
The graph records battery level over time and may mark charging, active screen use, screen-off periods, or sleep-related activity. The exact markers depend on the Windows build and hardware power model. Match a sharp drop to what happened at that time: a plugged-in period, a display-heavy task, a download, or standby.
A graph does not identify the cause by itself. Brightness, refresh rate, graphics hardware, wireless radios, peripherals, heat, and battery condition can all change the slope even when the same app is open.
Read and sort the app list
| View or sort option | What it means |
|---|---|
| Overall usage | Windows’ estimate of the app’s share of reported app activity during the selected period. |
| In use | Activity attributed while the app was in the foreground or actively being used. |
| Background | Activity attributed while the app was not the visible foreground application. |
| Name | Alphabetical ordering, not a power ranking. |
The percentage is not necessarily the percentage of the battery’s physical capacity consumed by that one app. It is a period-specific allocation and can be affected by how Windows attributes shared browser, helper, system, and graphics activity.
Rank #2
- 256 GB SSD of storage.
- Multitasking is easy with 16GB of RAM
- Equipped with a blazing fast Core i5 2.00 GHz processor.
Select an app to see its foreground and background details. Supported apps may show Manage background activity; this control is not guaranteed for every program.
How to decide whether an app is really a problem
- Check the workload. Streaming, gaming, rendering, compiling, virtual machines, and video calls normally use more energy than reading or writing documents.
- Compare foreground and background use. High foreground use may simply reflect active work. High background use despite little interaction deserves closer inspection.
- Repeat the observation. Look for the same pattern across several days or comparable sessions instead of acting on one ranking.
- Correlate resources. Use Task Manager to see whether the app or one of its helpers sustains CPU, GPU, disk, or network activity.
- Check system context. A discrete GPU, external display, dock, poor wireless signal, update, or antivirus scan may be the dominant drain.
Actions that can reduce unnecessary drain
When foreground use is high
- Close the app when finished.
- Lower video quality, frame rate, or other workload settings where appropriate.
- Try disabling hardware acceleration only if the app documents that option and performance remains acceptable.
- Update the app, Windows, and graphics drivers.
When background use is high
- Use Manage background activity when Windows exposes it.
- Reduce synchronization or polling frequency in the app’s settings.
- Disable unnecessary startup or tray behavior.
- Close helper processes through the app’s own exit command.
Do not disable background execution for backup, security, communications, accessibility, or synchronization software without understanding which notifications, uploads, protection, or accessibility features will stop.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsWhen the app is unresponsive
Save work first, then use Task Manager to end only a process you can identify as the affected application. Do not terminate arbitrary Windows system processes.
When the app remains problematic
- Repair or reset a Microsoft Store app from Settings > Apps > Installed apps > [app] > Advanced options, when those options are available.
- Uninstall software you no longer need.
- Contact the developer if abnormal activity continues after updating and reinstalling.
Why background controls may be missing
Packaged Microsoft Store applications can expose Windows background-permission controls. Traditional Win32 desktop programs commonly manage background work through their own settings, startup entries, scheduled tasks, services, browser processes, or tray components. Consequently, the absence of Manage background activity does not indicate a Windows failure. Inspect the program’s settings and, where necessary, Settings > Apps > Startup, Task Scheduler, or Services before disabling anything.
Use Task Manager to confirm the cause
- Press Ctrl + Shift + Esc.
- Open the Processes tab.
- Review CPU, memory, disk, network, and GPU columns.
- Expand an app to inspect related processes.
- End only a clearly identified application that is safe to close.
Task Manager is a correlation tool, not a guaranteed per-app wattage meter. Sustained CPU or GPU activity, a network-heavy helper, or a browser background process can explain why an app ranks highly in Battery usage.

Generate a Windows battery report
For capacity and longer-term history, open Command Prompt or Windows Terminal and run:
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →powercfg /batteryreport- Run the command.
- Note the file path Windows prints.
- Open the resulting HTML file in a browser.
The report can include design capacity, full-charge capacity, capacity history, battery-use periods, and recent or cycle information when supported by the hardware. Its sections vary with firmware, Windows release, and Modern Standby support. It complements—not replaces—the Settings page: the report focuses on battery condition and history, while Battery usage provides the current per-app view. General battery-report guidance is also summarized at UMA Technology.
Battery usage is different from battery health
Battery usage describes how quickly the present charge is being consumed. Battery health describes how much energy the battery can store now compared with its original design capacity. A demanding app can cause rapid drain without permanently damaging the battery; an aged battery can provide poor runtime even when software use is normal. Compare full-charge capacity with design capacity in the battery report before blaming an app.
When the Battery usage section is missing or incomplete
- Confirm that the computer is a laptop or tablet with a detected battery.
- Search Settings for Battery usage and check whether the section is collapsed.
- Choose Last 7 days if the 24-hour window contains too little activity.
- Restart after Windows updates and install manufacturer firmware and power-management drivers.
- Run
powercfg /batteryreportto determine whether Windows is receiving battery history. - Use Task Manager for live resource activity even when historical attribution is unavailable.
An app may be absent because it did not run in the selected period, Windows has not attributed measurable activity to it, it operates as a service or system component, or it runs inside another host process.
Quick Recap
Check hardware and system causes
- Lower screen brightness and, if practical, the display refresh rate.
- Disable HDR when it is not needed.
- Check whether a discrete GPU is active instead of integrated graphics.
- Disconnect unnecessary external monitors, USB devices, docks, and accessories.
- Review Wi-Fi or Bluetooth activity; connected PCs may also use more power with a weak cellular signal.
- Use a balanced or power-saving mode instead of high performance when full speed is unnecessary. Windows may call its reduced-consumption feature Battery Saver or Energy Saver, depending on release.
- Allow Windows Update, indexing, and antivirus scans to finish, or schedule them for suitable times.
- Close unneeded browser tabs and extensions.
- Check virtual machines, containers, developer tools, fan noise, and heat.
- Treat rapid loss during sleep as a separate Modern Standby, driver, firmware, network, or accessory problem rather than assuming a foreground app is responsible.
A practical troubleshooting sequence
- Open Power & battery > Battery usage and record the period, top apps, and foreground/background split.
- Repeat the check over a longer window if the result came from one unusual session.
- Compare the top app with Task Manager’s CPU, GPU, disk, and network activity.
- Close or limit the app using the least disruptive control available.
- Update, repair, reset, or uninstall it if the pattern persists.
- If drain continues after closure, inspect startup items, services, helper processes, browser background activity, graphics selection, updates, and peripherals.
- Generate a battery report when runtime remains poor or the device may have degraded capacity.
