Win10 new power saving mode function Laptop actual experience

The official version of the Windows 10 operating system has been released for several days. I believe many small partners can't wait to upgrade to Windows 10. The new Windows 10 not only brings Cortana voice assistant, Edge browser and other eye-catching features, but also Microsoft. In order to improve a lot of details, the "power saving mode" for mobile devices such as notebook tablets is one of the new features. I believe that you, like the author, are also keen to know if this new feature brings longer battery life for notebooks and other devices. Today, I will actually experience it through a laptop.

Windows 10 Power Saving Mode&####### The new Windows 10 operating system not only changes the system interface, but also improves a series of new features. Among them, "power saving mode" as a new feature first appeared in front of us. At this time, you may think of the power option that existed before Windows - energy-saving mode, which is different from the new "power saving mode"?

First, let's take a look at the "Energy Savings" option in the Windows Power Options. We can clearly see that the principle of "energy saving" mode is to save power by reducing the performance of the computer. Its depth adjusts the components in the whole system, including: hard disk energy saving, slide show frequency, WiFi module energy saving, graphics performance, processor performance, etc. can be adjusted. Therefore, the “energy saving” mode can control the performance from the bottom of the hardware to save power.

Next, let's take a look at the newly added "Power Save Mode" in Windows 10, based on what principle is used to save power. As you can see in the description interface, “Power Save Mode” is to extend the battery life by limiting background activity and push notifications. After the author's actual experience, when the "Power Save Mode" is turned on, the screen brightness will be reduced, but it is not displayed in the brightness adjustment of the system, for example: Turn on the brightness of the "Power Save Mode" For 50%, the screen brightness will be significantly reduced after turning on, but the screen brightness display is still 50%, which means that although the screen brightness is reduced, it does not affect the overall brightness adjustment mechanism of the system.

And, the quick switch of the energy-saving mode will also appear at the bottom of the notification center in Windows 10. As long as it is a mobile device such as a notebook or tablet, this shortcut switch will appear, but it will not appear in the desktop. appear. At the same time, the power save mode can only be turned on without a power connection.

As mentioned earlier, "power saving mode" is to extend the battery life by limiting background activities and push notifications. It is not clear how the specific working mechanism is. In the specific setting options, we can add some programs to keep running, but I found that only specific system applications can be added, and third-party applications (qq, Netease cloud music, etc.) can not be added, which allows the author to generate this function. Have doubts. Let's take a look at the actual test results.

Actual experience test:

After seeing the difference between the two, let's actually test the effect of “Power Save Mode”. First of all, I used the XPS 13 touch screen notebook as an experience model. We simulated the actual use by playing 2 hours of online video online. The test was divided into two sessions. The first time was not turned on, and the power was turned on. The second time was turned on. In the actual playback process, the power mode is kept balanced, the screen brightness is 50%, the volume is 20%, and the WiFi network connection is maintained. The power before the two tests is maintained at 80%.

Not turned on “Power saving mode”, Top: Power before test, Bottom: Power after test

Played for two hours without turning on “Power saving mode” The network video consumes 47% of electricity, which is estimated to be about 4.25 hours.





































The video consumes 40% of the power, which is estimated to be about 5 hours.

Compared with the opening, "power saving mode" can indeed bring longer battery life. However, from the actual experience of this article, the difference between the power consumption of the open and the unopened is 7%, and the estimated duration is 0.75 hours. Such a battery life can still bring a certain amount of time to the emergency office, and it can basically meet the emergency use requirements.

At the same time, the system will turn on this mode when the battery power is lower than 20% by default, but if the battery reaches 20% of the remaining power, it will not be as obvious as this article. Therefore, the author suggests that if you are concerned about the duration of the life, then try to adjust this parameter to 80% or more, and ensure that the power-on mode will be automatically turned on when the battery is fully charged. .

Full-text summary:

After reading this article, I believe that you have a certain understanding of the "power saving mode" in Windows 10. If you are using a Windows 10 device without a power source while on the go, turning on “Power Save Mode& quoquo; can indeed extend the battery life to some extent. Although there is no intrinsic modification of hardware such as batteries, "small power mode" is really practical.
