☑️ How to Generate and Read a Battery Report in Windows 11
– Reviews News
Lithium-ion batteries have been extremely useful in making devices super portable. However, these batteries should be replaced after a limited number of charge cycles. But how do you know if your laptop battery needs to be replaced? For this reason Windows allows you to generate a battery report which can be used to determine the health of your laptop's battery and help you decide if the battery needs to be replaced.
While a battery report sounds useful, generating one is more complex than navigating through the Battery section of the Settings app in Windows 11. That's why we've put together this step-by-step guide that simplifies the process for you. , followed by an explanation of how you can easily analyze the battery report you just generated.
How to Generate a Battery Report in Windows 11
Instead of using the conventional Settings app or Control Panel, you will need to run a simple command in the Command Prompt to generate a battery report on your Windows 11 laptop. Here are the steps to follow:
Step 1: Press Windows key + S and type System symbol. Then, from the command prompt results, click "Run as administrator".
Step 2: Click Yes when a User Account Control (UAC) prompt appears on the screen.
Step 3: Type the following command in the Command Prompt window and press Enter to generate the battery report.
powercfg /batteryreport /output “C:\battery-report.html”
The powercfg /batteryreport part of the command generates a battery report. The /output "C:\battery-report.html" part specifies the filename and location of the battery report to be saved to the particular location on your computer.
You can change the path and file name to your liking by replacing C: with any other drive letter and battery-report.html with something else.
You can also use the same command to generate a battery report using Windows PowerShell.
How to Access and Read a Battery Report
After generating a battery report, you may want to access and analyze it to determine the capacity and health of your laptop's battery. Here's how you can access your Windows laptop, followed by an explanation of how you can read it.
Step 1: Press the Win + E keys on your keyboard to open File Explorer.
Step 2: When the File Explorer window for this PC appears on your screen, navigate to the location where you saved the battery report.
If you didn't change the file location in the command above, you can find the battery report by clicking This PC, followed by your PC's C: drive.
Step 3: Locate the battery-report.html file and double-click it to open it in Microsoft Edge.

Once you have followed the steps mentioned above, you will see a battery report opened in a web browser as shown in the following screenshot:
The initial steps involved in generating and accessing a battery report may seem easy, but reading one with six sections of overwhelming information is another matter. Read on as we explain the use and function of each section of the battery report, which will make it easier for you to understand.
- Batteries installed: This section of the report provides a detailed overview of your laptop battery specifications. You can use this section to find the battery manufacturer, its capacity, its full charge capacity, and the number of times the battery has been charged and discharged during its lifetime, indicated by charge cycles.
- Recent use: This section of the report indicates when the computer has been actively used, idle/sleep, or connected to charger for three days.
- Battery usage: This section provides a graphical and tabular representation of battery drain over the past three days.
- Usage history: This section provides a tabular representation of when the battery was on battery power and when it was connected to a charger throughout its life.
- Battery capacity history: This section is responsible for displaying the evolution of the battery's charge capacity over its entire lifetime.
- Battery life estimates: This section of the report provides a calculated estimate of overall battery standby time based on your current charging capacity compared to when your laptop battery was relatively new.
The battery report gives you details such as how many hours your laptop has been charged, showing time on a single charge, model number and type of your battery to find a replacement battery compatibility, etc.
Know if it's time to replace your laptop battery
In addition to the information listed above, the battery report also provides an overview of your laptop's full charge capacity and design capacity (listed in the Installed Batteries section). You can use these two details to estimate if you need to replace your laptop battery as discussed in the next paragraph.
To determine if your laptop battery needs to be replaced, subtract the total charge capacity from the design capacity. If the subtracted capacity is less than half of the rated capacity, you will need to replace your laptop battery. If the battery capacity is decreasing, it means that your laptop battery cannot hold the same amount of power as when it was new. Therefore, you will need to charge your laptop more often to maintain the same screen time.
In our case, 48 mWh – 944 mWh = 26 mWh, which means the battery condition is slightly below rated capacity (706 mWh ÷ 22 = 238 mWh) and needs to be replaced . Let us know what results you were able to get, in the comments section below.
