- The vertical Y axis represents the percentage charge level factor (from 0-100%) and the horizontal X axis represents the sampling time factor. You can change the sampling time interval right on the screen configuration.

- The black line shows the current charge level; the blue line shows the trend based on estimated data samples; and the red line shows the battery life being compared. For example, when comparing short periods of time, the red line will be more skewed than usual.

- In addition, this software also shows detailed information about the discharge rate (in minutes) as well as helps you understand the level of deterioration in laptop battery health during use.

Check laptop battery without using software

First, from the main screen, press the Windows + R key combination to open the Run window as shown below, then enter cmd to open the Command Prompt window.

When the small and black window appears as shown below, continue to enter the following command: powercfg /batteryreport and press Enter. If you see the line Battery life report saved to C:., it means we have successfully extracted a report file about the battery status on the laptop .

Now, go to the User folder to read the battery health report file by doing the following: Open My Computer or This PC > Drive C > Users -> Your account name. Mine is like the picture below, the account name is Gabriel for example. Now, look down at the bottom row, there will be a file in the form of battery-report.html. This is the health report file of the laptop battery. If you see this file, you are almost done.

Then you can double click on the Battery-report file above to open the results using a web browser. The results will be returned as shown below.

In this file, scroll down a bit, to the Installed batteries section , look at the two lines Design Capacity and Full Charge Capacity. The Design Capacity line is the original capacity of the battery when it was first shipped and Full Charge Capacity is its actual "energy" storage capacity, based on the difference between these two numbers, we will know how much the laptop battery has deteriorated.

If the battery capacity gap between these two lines is too high, over 10,000 mAh, then you should probably replace the battery to ensure work performance, otherwise we can still continue to use it.

With the above extremely effective and accurate free laptop battery testing software , Hanoicomputer hopes to help you accurately check the quality of your laptop battery during use. Each software has different features and advantages and disadvantages, explore and evaluate for yourself which software is the best!
