If you find yourself constantly connecting your Windows 10 laptop to a power source, it could signal that your battery is no longer functioning optimally. Over time, laptop batteries wear out after a certain number of charge cycles, which leads to a shorter battery life. If you’ve already tried lowering screen brightness, limiting video usage, closing unnecessary applications, and even disabling Wi-Fi, yet the battery still drains quickly, it might be time to replace the battery.
Windows 10 allows you to assess the health of your battery through a simple command-line tool, which generates a Battery Report that provides detailed insights into your battery’s health and performance over time. Below, we will go over the steps to create this report and understand when it’s time for a battery replacement.
Step-by-Step Guide to Generate a Battery Report
Step 01: Open Command Prompt as an administrator.
- You can do this by typing CMD in the Start menu search bar, then right-clicking Command Prompt and selecting Run as Administrator.
Step 02: Run the battery report command.
- Type the following command and press Enter:
powercfg /batteryreport

Step 03: View the battery report location.
- After executing the command, a message will appear, showing the file path where the battery report has been saved.
Step 04: Access the report.
- Copy the file path provided (usually something like
C:UsersYourUsernamebattery-report.html) and paste it into your web browser to view the report.
Understanding the Battery Report
The Battery Report on Windows 10 offers a comprehensive analysis of your battery’s health and performance over time. Here are the key sections to focus on:
-
Primary Battery Information: This section provides details about the battery’s make, model, and chemistry.
-
Battery Capacity History: This part of the report shows how the battery’s capacity has diminished over time with use.
-
Battery Life Estimates: Windows calculates how long the battery should last in its current condition, based on historical data.

Key Metrics to Check:
-
Design Capacity: This indicates how much charge the battery could hold when it was brand new. It’s the original capacity when the laptop left the factory.
-
Full Charge Capacity: This shows how much charge your battery can currently hold. Over time, this number will reduce as the battery wears out.
For instance, if the report shows that your laptop battery was originally designed to hold 41,440 mWh but now only holds 20,720 mWh, this means the battery can still hold approximately 50% of its original charge. If the full charge capacity drops significantly below this, it’s a clear sign that the battery has degraded, and it may be time to replace it.
Conclusion
Using the Battery Report on Windows 10 gives a clear indication of whether your laptop battery is still in good condition or nearing the end of its life. By comparing the Design Capacity and Full Charge Capacity, you can make an informed decision about when it’s time for a battery replacement. If the full charge capacity is significantly lower than the design capacity, and you find yourself charging frequently, it’s a strong sign that replacing the battery would improve your laptop’s performance and extend its portability.
