Laptop batteries slowly lose capacity over time, which is why a device that once lasted all day may now drain much faster. Windows 11 does not show battery health directly in Settings, but it does provide reliable built-in tools to check your battery’s condition accurately.
This guide explains all working methods to check battery health on Windows 11, including the official Windows battery report and optional tools for easier analysis.
Method 1: Check Battery Health Using Windows Battery Report (Recommended)
Windows includes a hidden but powerful battery diagnostic tool that generates a detailed health report in HTML format.
Steps to Generate Battery Report
- Press Windows + S and type Command Prompt
- Right-click Command Prompt and select Run as administrator
- Enter the following command and press Enter:
powercfg /batteryreport- Windows will display the file location, usually:
C:\Users\YourUsername\battery-report.html
- Open File Explorer, go to that location, and double-click the file
How to Understand Battery Health in the Report
Your Windows 11 battery report shows two key values inside the Installed batteries section. These numbers help you understand how much capacity your laptop battery has lost over time.
What the values mean:
- Design Capacity – The original battery capacity when your laptop was new
- Full Charge Capacity – The maximum charge your battery can hold today
Windows calculates battery health using this simple formula:
(Full Charge Capacity ÷ Design Capacity) × 100Example from a real battery report:
- Design Capacity: 48,000 mWh
- Full Charge Capacity: 38,000 mWh
Battery Health ≈ 79%
Instead of calculating this manually every time, use the Battery Health Calculator below to get instant and accurate results.
Method 2: Save Battery Report to a Specific Location (Optional)
This method is useful if users cannot find the report file.
Command
powercfg /batteryreport /output "C:\battery-report.html"The report will be saved directly to the C drive, making it easier to locate.
Method 3: Check Battery Usage in Windows 11 Settings (Basic Info Only)
This method does not show health percentage, but it helps identify abnormal battery drain.
Steps
- Press Windows + I
- Go to System → Power & battery
- Scroll to Battery usage
You can see:
- App-wise battery drain
- Usage history
- Charging behavior
This is useful for troubleshooting fast battery drain but not battery wear.
Method 4: Use PC Health Check App (If Installed)
Some Windows 11 systems include PC Health Check, which may show battery capacity information in a simple format.
Steps
- Search PC Health Check in Start menu
- Open the app
- Check the Battery section (availability varies by system)
Note: This tool is not installed by default on all PCs.
Method 5: Use Third-Party Battery Health Tools (Optional)
Popular free tools:
- BatteryInfoView
- HWMonitor
- BatteryCare
These tools show:
- Battery wear level
- Charge cycles
- Current capacity
Windows’ built-in report remains the most accurate source.
Battery Health Status Guide
| Battery Health | Condition |
|---|---|
| 90–100% | Excellent |
| 80–89% | Good |
| 60–79% | Fair |
| Below 60% | Replacement recommended |
Tips to Maintain Battery Health on Windows 11
- Avoid keeping the laptop plugged in at 100% continuously
- Keep charge levels between 20% and 80% when possible
- Enable Battery Saver mode
- Avoid heat and blocked ventilation
FAQs: Battery Health on Windows 11
How do I check battery health on Windows 11?
You can check battery health on Windows 11 by generating a battery report using the built-in powercfg /batteryreport command in Command Prompt. The report shows design capacity, current full charge capacity, and battery usage history.
Does Windows 11 show battery health percentage?
No, Windows 11 does not display battery health percentage directly in Settings. You must use the battery report or third-party tools to calculate battery health manually.
What is the Windows 11 battery report?
The Windows 11 battery report is an HTML file generated by the system that provides detailed battery information, including capacity loss, charge cycles, recent usage, and estimated battery life.
Where is the battery report saved in Windows 11?
By default, Windows saves the battery report in the user folder, usually at C:\Users\YourUsername\battery-report.html. You can also choose a custom location using the output command.
What is a good battery health percentage for a laptop?
A battery health level above 80% is considered good. If battery health drops below 60%, replacing the battery is usually recommended for better performance.
Can I check battery health using Windows 11 Settings?
Windows 11 Settings only show battery usage and app drain history. They do not provide battery health or capacity information.
Is PC Health Check accurate for battery health?
PC Health Check can show basic battery capacity information on some systems, but it is not available on all Windows 11 devices and may not show detailed health data.
Are third-party battery health tools safe to use?
Reputable tools like BatteryInfoView and HWMonitor are generally safe, but Windows’ built-in battery report remains the most reliable and accurate source.
Why does my Windows 11 laptop battery drain faster over time?
Battery drain increases due to natural battery aging, reduced capacity, background apps, high screen brightness, and heat exposure.
How often should I check battery health on Windows 11?
Checking battery health once every 2–3 months is enough to track battery degradation and plan for replacement if needed.
Can battery health be improved on Windows 11?
Battery health cannot be restored once degraded, but you can slow further wear by avoiding constant 100% charging, reducing heat, and enabling Battery Saver.
Windows 11 does not display battery health directly in Settings, but the built-in battery report tool provides accurate and detailed information about battery condition, capacity loss, and usage history. Checking this report periodically helps you decide when battery replacement becomes necessary.
