But did you know you can actually track its health? By generating a Windows 11 battery health report, we can simply determine whether your laptop’s battery is healthy or needs to be replaced. Moreover, this report will also provide you with all the information you need to know about your laptop’s battery. This includes the battery name, manufacturer, serial number, chemistry, design capacity, full charge capacity, and much more. And guess what? All of this can be done with only Windows 11 OS. You don’t need to install any third-party software.

Let’s make sure that your laptop battery is charged at all times of need. All set? Now let’s proceed!

What is Battery Health in Windows 11?

Battery health in Windows 11 refers to a collection of data and diagnostics that provide insight into the current state and performance of your laptop’s battery. You can use this information to find out the capacity of your battery, how long it can maintain its charge, and whether it needs to be replaced.

When you first buy your laptop, the battery is at full capacity. However, its charge capacity decreases after several months of constant use and charging. It means that the battery will not last as long as when it was new. Battery health is simply how much of the original strength or charge your battery still has.

Steps to check Battery Health in Windows 11 using CMD/PowerShell

Let’s generate the Battery Health Report on your Windows 11 PC and plan whether or not you need a battery replacement.

Step 1. Open Windows Terminal

  • Right-click the Start button or press the Win + X keyboard shortcut.
  • From the menu, select Windows Terminal (Admin) to open the PowerShell window. Click Yes if you are asked for permission. Alternatively, you can also use CMD (Command Prompt) to check laptop battery health.

Step 2. Generate the Battery Report

  • Enter the following command in the Windows Terminal window and hit Enter:
powercfg /batteryreport
PowerShell window in Windows 11
  • This command tells Windows 11 to generate a detailed battery report and save it as “battery-report.html” in a user folder on your C: drive.

Check Windows 11 Battery Health using BatteryInfoView

Apart from CMD or PowerShell, you can also use third-party apps such as BatteryInfoView to check your Windows 11 laptop’s battery health. With BatteryInfoView, you can see your laptop battery’s capacity, current state of charge, and other general information.

It gives real-time data, allowing users to better understand their battery usage. Knowing how much power each operation consumes helps users improve their laptop’s power usage and, as a result, extend its battery life.

Understanding the Battery Health Report

The battery report is divided into multiple sections:

Installed Batteries

Compare Design Capacity and Full Charge Capacity in Battery Health Report on Windows 11

The Installed Batteries section displays the information about each battery installed in your laptop, such as its design capacity and full charge capacity. Here, you can see the initial capacity of the battery that your laptop came with, as well as the current charge capacity. So, if you calculate the difference, you can see how much your battery life decreased over time.

Recent Usage

Recent Usage section in Battery health Report

This section shows the battery’s consumption and charging patterns over the last three days. It includes start time, state, source, and the remaining capacity.

Battery Usage

Battery Usage section in Battery health Report

This shows the drain and charge cycles of the battery over the previous three days. It allows you to identify abnormal patterns or unusual power drains.

Usage History

Usage History section in Battery health Report

This section displays the battery’s usage history, including how frequently it has been charged and discharged.

Battery Capacity History

Battery Capacity History section in Battery health Report

Similar to the Usage History, this section compares the battery’s design capacity to its full charge capacity over time, showing any capacity declines.

Battery Life Estimates

Battery Life Estimates section in Battery health Report

This section displays the battery’s expected lifespan based on its initial design capacity and its actual current lifespan, using historical usage data.

When comparing the At Full Charge time to the At Design Capacity time in the Battery Life Estimates section, a large difference suggests that your battery is getting worse. This is normal because batteries lose capacity with usage, but a significant difference can indicate that it’s time to think about battery replacement.

Screen brightness, running heavy applications, and other usage patterns all affect the battery life span. Creating and analyzing the battery report frequently will help you track changes in your battery’s estimated life. This can help you take action to maintain the battery’s health before it becomes serious.

Tips to Improve Battery Life in Windows 11

  • Avoid Extreme Temperatures: Overly high or low temperatures will slowly damage the health of your laptop’s battery.
  • Use Battery Saver Mode: To save battery life, Windows 11 has a Battery Saver mode that lowers background activities and adjusts settings. Turn this feature on when your battery is almost dead.
  • Regular Use and Charging: Lithium-ion batteries in laptops perform best when you use them frequently and partially discharge them instead of draining them entirely before charging.
  • Update Your Software: Make sure your Windows 11 and all device drivers are up to date. Software optimizations can lead to better battery performance.

Wrapping Up

Isn’t it amazing how you can check the battery health of any Windows 11 laptop using this simple method? Now, based on the results, you can plan on whether or not you need to replace the battery.

Remember the old saying, ‘a stitch in time saves nine.’ Well, for us, a battery health check-in time saves nine (or more!) unexpected shutdowns.
