How to Generate a Battery Health Report on Windows 11 or 10?

Now, Laptops and tablets use rechargeable lithium-ion batteries. Like other batteries, lithium batteries have life spans. Then, you will notice performance degrades over time. Eventually, the battery won’t provide a charge after a long time of use. Most lithium-ion laptop batteries deliver 100% performance for the first year. Suppose you suspect that your battery is underperforming due to a manufacturing defect or something wrong with your system. In that case, you can generate a battery report from your Windows 11 and 10.

So, this handy battery report gives you a lot of information about your battery, including specs and service options depending on your system’s make, model, and age. For instance, if your battery or laptop is still under warranty and not performing well. Then you might be able to get a free replacement.

Then, all Windows versions, including Win 11 and 10, include a hidden feature known as Battery Report. Using this feature, you can quickly generate a report about your battery to see health information. How its capacity has decreased over time, and other interesting statistics.

After that, using the built-in command, “powercfg,” you can generate the report for battery through Windows Terminal, Command Prompt, or PowerShell. You can also use the “powercfg” command to generate an energy report, which suggests reducing your computer’s energy usage and extending its battery life.

How to Generate a Battery Report in Windows 11 or 10?

To generate a battery report in Windows 11 or 10, do the following steps:-
Step 1. Open Command Prompt, PowerShell, or Terminal app.
Step 2. Now, on the prompt, type the following and hit Enter key on the keyboard:-
powercfg /batteryreport
Previously, you execute the above command, and you will get the battery report at the following path:-
C:\Users\UserName\battery-report.html
So, the report provides details about your battery, including the name, manufacturer, serial number, chemistry, and cycle count.
How to Read the Battery Report?

When You get the battery report, navigate to the following path. Double-click on it and open it with the default browser on your PC:

C:\Users\UserName\battery-report.HTML

Battery report

The battery report is generated on a single HTML page divided into various sections. In the first section, you can find the computer name, system product name, BIOS, OS build version, whether the PC supports Connected Standby, and the time of the report when it was generated.

Installed batteries

The observe section, “Installed Batteries,” lets you know your installed batteries, name, manufacturer, serial number, chemistry, design capacity, total charge capacity, and cycle count.

It is the most critical section, and you need to learn it. In the screenshot above, you can see that the battery’s design capacity is 54,000 mWh, remaining the current full charge capacity is 46,530 mWh. It shows how your battery has worn down. Then the battery was initially designed for a 54,000 mWh capacity, but it can hold a maximum of 46,530 mWh. That means now it contains a little less charge than it was used. This number will reduce over time as you use your battery and put it through more charge cycles.

Tips: If you have purchased a new laptop, you may see a higher full charge capacity than its design capacity. That number will automatically decrease over time as the battery chemistry changes.

Recent Usage

You see the above screenshot, the “Recent Usage” section of your battery report displays the device’s power states over the last three days. Here, you can find when your device started. When it was suspended, and how much battery capacity drained over time.

Battery usage

Only it displays data for the last three days. The “Battery usage” section shows how your battery drained over time.

Usage history

Here, it displays your battery’s usage and duration over time. You can find how much time the device spent on battery power. How much time is it spent plugged into a power outlet? The statistics here display the report from the date of installation of the device when you have first powered on after the initial purchase.

Battery capacity history

This interesting section shows you how your battery’s total charge capacity gradually decreased over time compared to its design capacity. At the same time, you can find the statistics here from the original setup date of Windows on the computer.

Battery life estimates

Then, this displays an estimate of your device’s average battery life for different periods, based on how you used it. It compares observed battery life at the device’s entire charge to theoretical battery life at its design capacity.
