How does the Win10 system view the laptop battery status?

1. Run CMD as administrator and enter the following command to enter. The system will generate a device battery usage report on the path you specify.
powercfg /batteryreport /output “C:battery_report.html”

2. Double-click C:battery_report.html to open the report with your default browser. Let's take a quick look:
(1) System and battery basic information, including battery design capacity, full charge capacity, and charge cycle.

(2) The battery fully charged capacity changes.

(3) A record of battery usage for the last three days, including when it is active and when it enters standby.

(4) The battery usage curve for the last three days.

(5) The battery life estimate changes, the data here is more accurate than what you see on the taskbar battery icon.

3. This report will record in detail the usage details of the battery after the system is installed. Based on these data, you can grasp the battery life changes.
