How to check battery status and capacity in Windows 11

Lithium-ion batteries are one of mankind’s greatest inventions. They have already helped us develop portable electronic devices and electric vehicles and are on the verge of conquering the networked energy storage market.

But like all good things, lithium-ion batteries have their drawbacks. Lithium-ion batteries lose their charge capacity when repeatedly recharged. In addition to losing their charge, a weakened battery will also cause low power output or dangerous situations such as swollen/swollen batteries, especially when used in a device such as your smartphone or laptop, which generate both heat and lack proper battery cooling solutions. normally found in EV batteries.

That’s why we’ve created this step-by-step guide on how to check your Windows 11 laptop’s battery health and capacity using the built-in software tools to determine if it needs to be replaced.

How to Generate Battery Health Report in Windows 11?

By default, Windows 11 allows you to generate battery health reports by typing specific code in the built-in command line applications i.e. Command Prompt (CMD) or PowerShell. The following describes how you can use both CMD and PowerShell to generate a battery report in Windows 11 using the same code:

  • Press Windows key + R to open the Run dialog box.
  • In the Run dialog box, type CMD or PowerShell, then click OK or press Enter.

  • As soon as you receive the message “Battery life report saved in file path”, note the file path/save location listed next to it.

How do I find and read a battery status report?

Now that you have successfully created a battery health report by following the steps listed in the previous section, the next step is to find and read the battery health report to determine if the battery of your laptop needs to be replaced or not.

To find the battery health report, navigate to the path we have already mentioned, i.e. C:Users”Your username,” and double-click the battery-report.html file to open it in your default web browser.

If the battery report file is opened in your web browser, you will notice that it is divided into several sections containing different information about your laptop’s battery. Here’s what it all means:

  • Batteries installed: This section provides a general overview of the batteries installed in your laptop. It includes manufacturer, serial number, battery chemistry/type, capacity and number of charge cycles, i.e. the number of times the battery has been charged over its lifetime of life.
  • Recent use: This section indicates when the computer was active, suspended, or connected to the charger in sleep mode.
  • Battery Usage: This section displays a graph representing battery drain over the past three days.
  • Usage history: This section records how long the computer has been running on battery power and when it has been connected to a charger.
  • Battery capacity history: This section tracks and displays the battery charge capacity history.
  • Battery life estimates This section, as the name suggests, gives an estimate of the expected battery life based on the current charge capacity and power consumption.

How do you determine if your laptop needs a battery replacement?

Once you’ve run a battery health report, it’s pretty easy to determine if your laptop needs a new battery. Note that the “design ability” and “full load capacity” are both listed in the Installed Battery section of the Battery Health Report.

If the difference between the two capacities is not very large, you should not worry about replacing the battery. However, if the total charge capacity drops significantly below the 50% mark, you’re out of luck and should replace your laptop battery as soon as possible.

5 Tips to Preserve Battery Life in Windows 11

Now that you know how to generate and read a battery health report in Windows 11, let’s look at some useful tips you can use to improve and maintain your laptop’s battery life in Windows 11.

1. Try using a different power plan:

Windows 11 and all earlier versions of Windows give you the option to choose between three power modes, including:

  • Best performance: As the name suggests, this power plan helps keep your PC fast and responsive by delivering more power to the CPU and other components without worrying about power efficiency.
  • Balance: The default power plan used by Windows provides a combination of power and battery performance with balanced power consumption.
  • Better energy efficiency: Third and best of the three options, Better Power Efficiency mode provides longer battery life than your system’s default settings by reducing screen brightness and disabling background processes.

Choosing a power saving plan based on your current workload can help preserve your laptop’s battery life. To change power plan in Windows 11, go to Settings > System > Power and batteryand select a power plan from the drop-down menu under Supply Mode.

2. Adjust screen sleep and screen off time:

If you frequently leave your computer unattended, consider reducing the hibernation time and turning off the screen. This will help reduce the overall battery consumption of your laptop.

To set the time for the screen to sleep and turn off, open the settings > Power and battery > Screen and sleep and select your preferred times from each drop-down menu.

3. Try using dynamic refresh rate on laptops with high refresh rate displays

Dynamic Refresh Rate (DRR) only applies to gaming laptops with high refresh rate displays. It allows your computer to dynamically adjust the refresh rate between 60 and 144Hz based on what’s on the screen instead of streaming 144Hz frames.

While this does degrade image quality and overall responsiveness of a display, it is very helpful in preserving your laptop’s battery life. To activate it, go to Settings > System > Advanced display and select Dynamic under the refresh rate drop-down menu.

4. Try using dark mode

Your screen consumes less power than usual when you enable dark mode. So it would be helpful for you to use dark mode and dark theme to improve your Windows 11 battery life.

You can enable dark mode on Windows by going to Settings > Personalization > Colors then selecting Dark under Mode.

Windows 11 Battery Health and Capacity Check FAQ

However, your laptop is smart enough not to “overload” and hurt itself due to excessive load. It would help if you were trying to keep the battery level at or below 80%.

You can charge a laptop while you are using it. However, it is still recommended to charge it when it is off, as this helps the laptop charge faster.

No, Windows 11 has no battery issues. It comes with a fast boot feature that you can enable to reduce system boot time.

However, on the other hand, this feature consumes much more battery to deliver fast boot times. You can try disabling this feature to improve your laptop battery performance.

One of the most common symptoms of a bad battery is that your laptop is plugged in and still draining quickly. A faulty power adapter can be the cause, but it’s usually due to a bad battery.

A laptop battery that is not charging properly can cause your laptop to run slower than usual. This will also cause the computer to shut down earlier than expected. A laptop with a bad battery will also have a shorter lifespan than it should.

You can determine if your laptop needs a battery replacement by subtracting the “Full Charge Capacity” from the “Design Capacity”.

If the difference is not big, then everything is fine. However, if the total charge capacity drops below the 50% mark, you should consider replacing your laptop battery.
