When you are not getting enough battery backup on your Windows 10 device, you might want to check the current battery capacity so that you can replace the battery if the battery cannot hold at least 50% of its original capacity.
Complete the given below directions to know the current storage capacity of your Windows 10 laptop or tablet battery.
Step 1: Open the Command Prompt with administrator rights. To do that, type CMD in the Start/taskbar search field, right-click on the Command Prompt entry and then click Run as administrator.
Click Yes button upon getting the User Account Control prompt.
Step 2: At the Command Prompt window, type the following command:
Hit the Enter key to execute the command.
Step 3: When you execute the above command, Windows 10 creates and saves a battery report to C:\Windows\System32 folder.
Step 4: Navigate to C:\Windows\system32 folder and open the battery-report.html file. It can be opened with any web browser.
Step 5: In the battery report, in the Installed batteries section, you can find both the design capacity as well as the full charge capacity of the battery (batteries). The design capacity represents the amount of charge the battery was originally designed to hold. The full charge capacity is nothing but the current storage capacity of the battery.
If you scroll down the page, you will see a section called Battery capacity history. The table shows how your battery’s storage capacity has declined over time. The full charge capacity of the battery will be close to the design capacity when its new. The full charge capacity drops with time.
When the full charge capacity of the battery drops to less than 50% of the design capacity, you might want to consider replacing the battery.
