Before I saw a criticism that Windows 10 is very power-hungry when the device is battery-powered, there are also reports that this is caused by bugs, Microsoft and Intel have been optimizing and processing. If you think your use is affected, be sure to update your system and drivers regularly.
Power Saving Mode
Currently, Windows 10 has deployed more than 1 billion devices, so we believe that Microsoft has more data to count, analyze and optimize power management for portable devices.
"Power Saver Mode" allows Windows 10 to automatically control the screen brightness, CPU operating frequency and other power users, allowing the system to maximize Windows 10 battery usage in the background. When you use the battery, you can select "Power Save Mode" by clicking the battery icon in the task bar.
When the power save mode in Windows 10 is turned on, it will automatically:
suspend email and calendar updates
suspend updates to dynamic posts
limit background apps
suspend push notifications for apps
>How do you want to have more granular control over the "Power Save Mode", you can manually adjust the power save mode &mdash on the left side of the settings (Windows + I) — System & mdash;
Please turn on the power save mode automatically when you manually or configure the battery below XX%. It allows us to automatically get the power optimization function.
PowerCfg
PowerCfg is a command-line tool for adjusting power settings in Windows that generates a list of applications that have the right to wake up a computer device. Some Windows applications set a "wake-up timer" to let the operating system perform certain tasks at regular intervals. For example, Windows Update can wake up the computer to automatically patch when we sleep. But if your notebook is not connected to a power source, the battery may have been consumed in the morning.
In response to the appeal, we can use the powercfg –devicequery wake_armed command to list the current list of applications in Windows 10 that have the right to wake up the computer. If you find an unwanted application, you can choose to turn it off.
For the Windows 8/8.1/10 operating system, not all devices support all sleep states, depending on the hardware and drivers you use, and compatibility with Windows. Use the powercfg /a command to see which sleep modes are currently supported by the system when needed.
Maybe the most useful is the powercfg /energy command. Execute this command to track the system's 60 second usage behavior and generate a power efficiency diagnostic report that explains your system performance, like this:
The command line will output the number of errors and warnings. There is very detailed information in the generated energy-report.htm power efficiency diagnosis report. You can go and see it yourself. I won't say it here.
Finally, a powercfg /batteryrepor parameter is generated, which can generate battery reports, including: battery usage in the last 3 days, battery design power, current battery full capacity and battery type.
Power Plan
Power Plan is a long-standing feature in Windows that helps users control when screen power is turned off, when the monitor turns off automatically, and when it goes to sleep automatically when using power or external power. control.
In Windows 10, we can still use the "Control Panel" to control the battery plan, or you can select the power and sleep — on the right side of the settings (Windows + I) — System — (Click "Other Power Settings" to open the power plan configuration interface in the control panel)
