Go to the start menu and then find “PowerShell” or “Command Prompt”. After that right-click on the icon and select “Run as administrator”. Then enter the command powercfg /batteryreport /exit “c:\batteryreport.html” and press Enter.
If you do not have administrator rights, use the following command: powercfg/battery report.
If an error occurs while running the command, make sure that the “Diagnostic Policy” in the Windows Services Manager (services.msc) is enabled.
The report will be provided in HTML file format. Simply double-click on it to view it. Then, scroll down to “Battery Capacity History” and find the most recent entry in the list. On the left is the full charge capacity in mWh, and on the right is the initial capacity.
To check the battery status, click on the Apple logo in the left corner of the screen. Then select System Preferences and Battery. After that, go to battery settings.
In the settings, it will say that the battery status is normal or maintenance is required. On laptops with Apple Silicon chips, you will be able to see the capacity percentage compared to the battery.
To find out the number of charge cycles, go to “System Information”. You can launch this application through Spotlight or the Applications – Utilities folder. Then open the “Nutrition” section.
Checking the battery status in this case is as easy as on a MacBook. Go to Settings in the left sidebar, then About ChromeOS. Then in the “Diagnostics” section, you can see the time until the device is fully charged, the battery percentage, the number of charge cycles, and how much energy is being consumed at the moment.
