Look at the application first:
Open cmd input
powercfg/batteryreport
Press Enter to view the battery usage report from the last reinstallation of the system to the present
Introducing powercfg
powercfg.exe is a Windows device experience/modern standby/test and diagnosis/Powercfg command-line option component. Use powercfg.exe to control the power plan (also called power plan) to use the available sleep states and control the power state of a single device , And analyze common energy efficiency and battery life issues in the system.
Rules of Use
The Powercfg command line uses the following syntax:
powercfg /option [arguments] [ /? ]
Among them, option is one of the options listed in the following table, and arguments are one or more parameters applied to the selected option. Including /? in the command line will display help for the specified option. Options and parameters will be described in more detail later in this topic.
