How to Assess Your Battery’s Health on Windows 10

Battery life has become a key factor for Windows 10 users who want their laptops to be more portable than ever. Getting the most out of your battery is important, so you may need to check your battery life in Windows 10. In this guide we'll show you how. On the surface, Windows 10 doesn't provide detailed information about battery performance. When you select the battery icon in the system tray, you will get basic information about the remaining battery life and how to charge it. Luckily, you don't need to download laptop battery checking software and can generate a complete battery report right in Windows 10. Certainly, it's important to understand battery performance, and reading the manufacturer's specifications won't cut it. There is always a big gap between manufacturer information and real-world performance.

This is because advertised possibilities can only be achieved under unrealistic conditions. However, if your Windows 10 laptop or tablet battery is significantly slower than the advertised runtime, it may be faulty. When this happens, the Windows 10 battery report will quickly highlight any possible issues. When you create a report, it will show detailed battery information every minute. For example, you can see how a battery's charge when new and current is performing by making a comparison.
With this information, you can decide if you need to buy a new battery.

How to create and read Windows 10 battery report Windows 10 powercfg battery reports can only be generated with the PowerShell command which will store a static html file on your disk. This html file can then be opened in any browser. To update Windows 10 battery report, you will have to repeat the process. Then the battery report file will be overwritten / updated. 1. Open Windows 10 PowerShell You can quickly open PowerShell through the Start context menu, which can be accessed by right-clicking the Start button or using the Windows Keys + X hotkey.

2. Generate Windows 10 battery report To generate a new battery report, run the command powercfg /batteryreport. Windows 10 will show you where the corresponding HTML file has been saved. The standard location is C:\battery-report.html We have uploaded the sample report we used in this guide for your convenience.
3. Open the Windows 10 battery report using the web browser You can open the battery report by dragging the pin-report.html file to your browser window. At the top, you'll find your system's basic specifications and the date and time you generated that specific battery report.
4. Review the main specifications of the battery In the Installed batteries section, you can compare the maximum capacity (design capacity) when the new battery is new to the current maximum (fully charged capacity) and determine if your battery is still as good as possible. how. You will also see the installed battery model, the manufacturer, and the number of charge / discharge cycles completed.
5. Review recent battery usage data Under Battery Usage, you will find a graph of battery charge level over the past three days. There, you can visually understand how fast or slow the battery is during operation. The Recent usage section shows more detailed information about the last three days of use, including when the battery was plugged in and the charge level changes across different power states (Connected connections in Standby, Active, Pause).
6. Review detailed battery usage history Moving down the Windows 10 battery report, Usage History follows the same model as the Recent Usage section but provides a broader look at your battery performance over weekly periods. This table details all battery usage through the history of use from new to present. You can view the battery life hours used per week, as well as AC standby and connection time.
7. Review battery capacity history If you want to see how your battery capacity has been maintained since you unpacked your laptop, the Battery capacity history section can help. Here, you can compare the fully charged capacity of the battery with its design capacity over time. As the chemical reaction of the battery slowly declines, the maximum charge capacity will slowly decrease. This is a good metric to check when buying a refurbished / old laptop.
8. Review battery life estimates over time The Battery Life Estimates section shows data organized by the running time between two charge cycles. To check the battery capacity, you can fully discharge a fully charged battery in different consumption scenarios.
9. Review overall battery life estimate At the end the Windows 10 powercfg battery report will show a Current estimate of battery life based on all observed drains since Windows 10 was installed.
