How to check the battery health of a laptop?

Signs of a Weak Laptop Battery

These are some signs of a weak laptop battery:

• The batteries of most laptops can last up to 10 hours, and if the charge only lasts for 15 to 30 minutes, it’s time for a replacement.

   

• If your laptop does not charge at an average speed, an inefficient battery may be the cause.

   

• With a faulty battery, the laptop may randomly turn off even when it’s fully charged. 

   

• When your laptop overheats for an extended period and even the internal fans cannot cool it off effectively, it may be a sign of a weak battery.

   

• A lot of laptops now have alerts that inform the user about the need for a battery replacement. 

   

• If the area near your trackpad or keyboard looks bloated, then it may indicate that your battery is damaged.

   

How to Check Battery Health on Windows

You can check laptop battery health on your Windows device through the following method:

• Go to the Start menu and search for ‘Command Prompt’ and open the application.

   

• Proceed to type in ‘powercfg’ or ‘batteryreport’ and press the Enter key.

   

• After this command, a detailed HTML report or file is created. 

   

• Navigate to the created folder and open the HTML file in the web browser.

   

• In this report, details like full charge capacity, usage history, and design capacity are available. 

   

• A significant difference between the full charge and design capacities indicates a battery issue.

   

How to Check Battery Health on Mac

Here are laptop battery status check methods for a Mac:

• Click the Apple icon, available in the upper left corner of the screen.

   

• Next, click on the ‘About This Mac’ option.

   

• Keep a note of your MacBook model. 

   

• Click on the ‘System Report’ option and navigate to Power in the sidebar.

   

• Now the ‘Battery Information’ section will be visible, wherein the user can access ‘Health Information.’

   

• If the battery is to be replaced owing to deterioration, a message like ‘Replace Soon’ is displayed.

   

Tools and Commands for Battery Health Check

The following are some commands and tools to check laptop battery health:

• On a Windows laptop, you can search for the ‘Command Prompt’ and type in ‘powercfg’ or ‘batteryreport’ for a battery health report.

   

• You can use a third-party tool like ‘HWMonitor’, which helps keep track of temperature, voltage, and charge rate. 

   

• For some Windows devices, you can check battery health using BIOS. To open these settings, press the F2 key repeatedly and proceed to look for an option like “Battery Health.”

   

• For macOS, alongside checking battery health through the settings, you can also evaluate it using a third-party app like ‘coconutBattery.’

   

Tips to Maintain Good Battery Health

Here are some ways to monitor laptop battery health and maintain it:

• Store your laptop with the battery charged below 50%, as storing fully charged devices often reduces battery capacity.

   

• Avoid charging your device at an elevated temperature, as it can deteriorate lithium-ion batteries. 

   

• Avoid full discharges regularly; keep it between 20–80% when possible.

   

• Make sure that the software, firmware, and drivers are updated, as this can improve battery efficiency.

   

Conclusion

Once you understand your laptop’s battery health, you can take better care of it to ensure excellent performance. Checking battery health is a simple task and can be performed without complications by Windows and Mac users. Combine regular monitoring with good habits, and you’ll extend the life of your device and boost your productivity.
