^(Microsoft)从2017 年 10 月发布的^{(October 2017)}Fall Creators Update（内部版本 1709）开始，Microsoft设计了一种在Windows 10中实现电池节省的新方法。它在大多数人不会更改的经典电源计划之上添加了新的省电^{(power saving)}算法和技术。^{(algorithms and technologies)}Windows 10现在使用最新处理器中存在的现代节能^{(power saving)}功能和性能限制机制。^{(performance throttling)}以下是新的电源滑块^{(power slider)}在Windows 10中的工作方式，以及如何使用它来延长电池寿命或性能^{(battery life or performance)}，具体取决于您的需求：

如何在Windows 10中使用^{(Windows 10)}电源滑块^{(power slider)}

您可以在使用电池运行的笔记本电脑、平板电脑和可转换设备上访问Windows 10 Fall Creators Update或更新版本中的新省电功能。要访问电源滑块^{(power slider)}，请单击或点击系统托盘^{(system tray)}中的电池图标^{(battery icon)}。

将显示一个弹出窗口，您可以在其中看到有关剩余电量以及活动“电源模式”的详细信息。^{("power mode.")}还有一个带有三个或四个位置的滑块。如果您的 Windows 10 设备已从电源插头^{(power plug)}断开并依靠电池运行，则滑块有四个位置：最佳电池寿命、更好的电池^{(Best battery life, Better battery)}（或推荐^{(Recommended)}）、更好的性能^{(, Better performance)}和最佳性能^{(Best performance)}。根据您的需要，将滑块移动到所需位置，以提高电池寿命或系统性能^{(battery life or system performance)}。

如果您的 Windows 10 移动设备已连接到电源插头^{(power plug)}，则滑块具有三个位置：更好的电池、更好的性能^{(Better battery, Better performance)}和最佳性能^{(Best performance)}。您可能会问：为什么连接电源插头时^{(power plug)}电池更好^{(Better battery )}？一个很好的问题，微软^(Microsoft)没有回答。🙂

当你改变它的位置时，电源滑块^{(power slider)}有什么作用？

我们说电源滑块^{(power slider)}有三个或四个位置，这取决于您是否连接到电源插头^{(power plug)}。以下是每个职位的作用：

• 最佳电池寿命- 当您的^{(Best battery life)}Windows 10设备未连接到电源^{(power source)}时，可以最大限度地节省电量。使用此模式并激活省电模式时，某些^{(battery saver)}Windows 10功能会被禁用、限制或行为不同。屏幕亮度^{(Screen brightness)}也显着降低，以降低能耗^{(energy consumption)}。
• 更好的电池^{(Better battery)}- 提供比以前版本的Windows上的^(Windows)默认电源计划^{(default power plan)}设置更长的电池寿命，但低于以前的电源滑块级别^{(power slider level)}。它不会降低屏幕亮度^{(screen brightness)}，并且会稍微减少功率节流^{(power throttling)}。在某些情况下，用户会在其电源滑块中看到此模式标记为“推荐^{(Recommended)}”，而不是“更好的电池”。^{(Better battery)}
• 更好的性能^{(Better performance)}- 这是默认的电源滑块模式^{(default power slider mode)}，它略微偏向于性能而不是电池寿命^{(battery life)}，适用于希望在使用应用程序时以功率换取更好性能的用户。
• 最佳性能^{(Best performance)}- 性能优于节能。它面向希望为其游戏和应用程序提供最佳性能的用户。如果您想要电池寿命，这是使用的最差功率滑块级别^{(power slider level)}。

电源滑块^{(power slider)}与电源计划有何不同？

在旧版本的Windows中，仅通过电源计划^{(power plan)}或电源方案配置电源设置。电源计划^{(power plan)}是管理计算机或设备如何使用电源^{(computer or device uses power)}的硬件和系统设置^{(hardware and system settings)}的集合。例如，电源计划^{(power plan)}设置以下元素在使用电池和连接到电源^{(power source)}时的行为方式：

• 屏幕亮度^{(screen brightness)}，当显示器变暗和关闭时
• 当电脑休眠时
• 当硬盘关闭时
• Internet Explorer 和 Microsoft Edge 渲染网页的^{(Internet Explorer and Microsoft Edge render web pages)}速度
• 桌面背景^{(desktop background)}多久改变一次
• 你的无线网卡的性能^{(wireless network card)}
• USB设备在不使用时挂起的速度有多快
• 显卡用了多少电量
• 当您合上设备的盖子或按下电源按钮时会发生什么^{(Power button)}
• 系统中的 PCI-Express 卡使用了多少电量
• 处理器 ( CPU ) 的主动电源管理^{(power management)}功能
• 多媒体如何在屏幕上呈现（视频播放质量^{(playback quality)}等）
• 您收到的通知取决于您的电池电量^{(battery level)}和电池使用情况^{(battery use)}

电源滑块是您的^{(power slider)}电源计划^{(power plan)}之上的一个叠加层，具有传统电源计划^{(power plan)}中不存在的附加功能。这是电源滑块级别^{(power slider level)}管理的内容：

• 处理器 ( CPU )的操作模式^{(operating mode)}，以提高电池寿命或性能^{(life or performance)}，取决于用户想要什么
• 后台应用程序和 Windows 进程^{(background apps and Windows processes)}的优先级，以便在您想尽可能节省电池时以最省电的方式使用它们
• 屏幕亮度

在技​​术方面，电源滑块^{(power slider)}仅处理电源限制算法^{(power throttling algorithms)}在Windows 10中的工作方式。它不会更改您的电源计划^{(power plan)}及其设置。它是在活动电源计划^{(power plan)}之上的一层。

Windows 10中缺少电源滑块^{(power slider)}。这是为什么？

电源滑块^{(power slider)}并非在所有装有Windows 10的系统上都可用。首先，它是在^(First)2017 年 10 月发布的^{(October 2017)}Fall Creators Update（内部版本 1709）中首次引入的。如果您使用旧版本的Windows 10，则没有此功能。此外，电源滑块^{(power slider)}仅适用于具有电池的移动Windows 10设备，不适用于台式电脑和其他始终插入电源^{(power source)}的计算机。

电源滑块^{(power slider)}仅适用于采用AMD和 Intel 处理器^{(AMD and Intel processors)}、采用Intel Speed Shift技术或类似技术的系统。例如，它适用于 2015 年8 月发布的^{(August 2015)}英特尔^(Intel)第 6 代Skylake处理器。较新的 AMD Ryzen 和 Intel 处理器^{(Newer AMD Ryzen and Intel processors)}都支持此功能。

另一个问题是电源滑块^{(power slider)}仅在使用Windows中默认的平衡^(Balanced) 电源计划^{(power plan)}时才有效。如果您将电源计划^{(power plan)}更改为高性能^{(High Performance)}或其他，电源滑块^{(power slider)}将不再可用。

确保^(Make)将活动电源计划^{(power plan)}更改为Balanced或系统制造商提供的默认值。在某些移动系统上，只有一个电源计划^{(power plan)}可用，由设备制造商创建。

如果你做了所有这些，你有一个兼容的处理器，你仍然看不到电源滑块^{(power slider)}，那么你就不走运了。似乎Windows 10中存在一个错误，导致此问题出现在某些系统上，目前还没有人找到修复程序。如果您这样做了，请在下面的评论中告诉我们，我们承诺会更新这篇文章，以便我们可以帮助遇到此问题的其他人。

您使用电源滑块^{(power slider)}吗？您对此功能的满意度如何？

微软^(Microsoft)声称，Windows 10中引入的电源滑块^{(power slider)}和电源节流可以节省高达 11% 的能源。试试这个功能，看看它是如何工作的，让我们知道你是否同意微软^(Microsoft)的说法。这是您在装有Windows 10的移动设备上工作时所寻找的吗？在下面发表评论，让我们讨论。

Use the Windows 10 power slider to save battery or increase performance

Microsoft designed a new way to approach battery saνings in Windowѕ 10, starting with Fall Creators Update (buіld 1709), which wаs released in October 2017. It adds new power saving algorithms and technologies, on top of the classic power plans that most people do not change. Windows 10 now uses the modern power saνіng fеatures and performаnce throttling mechanisms that exiѕt in the latest proceѕsors. Here is how the new power slider workѕ in Windows 10, and how to use it to increase battery lіfe or performance, depending on what you want:

How to use the power slider in Windows 10

You can access the new power saving features in Windows 10 Fall Creators Update or newer, on laptops, tablets, and convertible devices that run on battery. To access the power slider, click or tap the battery icon in the system tray.

A pop-up is shown, where you see details about how much battery is left, and the active "power mode." There is also a slider with three or four positions. If your Windows 10 device is disconnected from the power plug and runs on battery, the slider has four positions: Best battery life, Better battery (or Recommended), Better performance, and Best performance. Move the slider to the desired position, to improve battery life or system performance, depending on what you want.

If your Windows 10 mobile device is connected to the power plug, the slider has three positions: Better battery, Better performance, and Best performance. You may ask: Why Better battery when connected to a power plug? A good question, with no answer on Microsoft's part. 🙂

What does the power slider do when you change its position?

We said that the power slider has three or four positions, depending on whether you are connected to a power plug. Here is what each position does:

• Best battery life - conserves the most power when your Windows 10 device is not connected to a power source. When this mode is used, and the battery saver is activated, some Windows 10 features are disabled, throttled, or behave differently. Screen brightness is also reduced significantly, to lower energy consumption.
• Better battery - delivers longer battery life than the default power plan settings on previous versions of Windows, but less than the previous power slider level. It does not decrease the screen brightness, and it does slightly less power throttling. In some cases, users see this mode labeled Recommended, rather than Better battery, in their power slider.
• Better performance - it is the default power slider mode that slightly favors performance over battery life and is appropriate for users who want to trade power for better performance when using their apps.
• Best performance - favors performance over power savings. It is targeted at users who desire the best performance possible for their games and apps. If you want battery life, this is the worst power slider level to use.

How is the power slider different from power plans?

In older versions of Windows, the power settings were configured only through power plans or power schemes. A power plan is a collection of hardware and system settings that manage how your computer or device uses power. For example, the power plan sets how the following elements behave when on battery and when connected to a power source:

• The screen brightness, when the display dims and turns off
• When the computers sleeps
• When the hard disk turns off
• How fast Internet Explorer and Microsoft Edge render web pages
• How often the desktop background changes
• The performance of your wireless network card
• How fast USB devices are suspended when they are not used
• How much power is used by the graphics card
• What happens when you close the lid on your device or when you press the Power button
• How much power is used by the PCI-Express cards in your system
• The processor's (CPU) active power management features
• How multimedia is rendered on the screen (video playback quality, and so on)
• The notifications you get depending on your battery level and the battery use

The power slider is an overlay on top of your power plan, with additional features that do not exist in traditional power plans. Here is what the power slider level manages:

• The operating mode of the processor (CPU) to enhance battery life or performance, depending on what the user wants
• The priority of background apps and Windows processes, so that they are used in the most power-efficient manner when you want to save as much battery as possible
• The screen brightness

In technical terms, the power slider only handles how power throttling algorithms work in Windows 10. It does not change your power plan and its settings. It is a layer that comes on top of the active power plan.

The power slider is missing from Windows 10. Why is that?

The power slider is not available on all systems with Windows 10. First of all, it was first introduced with Fall Creators Update (build 1709), which was released in October 2017. If you use an older version of Windows 10, you do not have this feature. Also, the power slider is available only for mobile Windows 10 devices that have a battery, not for desktop PCs and other computers that are always plugged into a power source.

The power slider works only on systems with AMD and Intel processors, that have the Intel Speed Shift technology or similar technologies. For example, it works with Intel's 6th generation Skylake processors that were released in August 2015. Newer AMD Ryzen and Intel processors all support this feature.

Another issue is that the power slider works only when using the Balanced power plan that is the default in Windows. If you change your power plan to High Performance or something else, the power slider is no longer available.

Make sure to change the active power plan to Balanced, or the default provided by your system's manufacturer. On some mobile systems, there is only one power plan available, created by the manufacturer of the device.

If you did all this, you have a compatible processor, and you still do not see the power slider, then you are out of luck. It seems that there is a bug in Windows 10 that makes this issue appear on some systems, and nobody has found a fix yet. If you did, let us know in the comments below, and we promise to update this article so that we can help others having this issue.

Do you use the power slider? How satisfied are you with this feature?

Microsoft claims that the power slider and the power throttling that was introduced in Windows 10, can deliver up to 11% in energy savings. Try this feature, see how it works and let us know whether or not you agree with Microsoft's claims. Is this what you are looking for when working on mobile devices with Windows 10? Comment below and let's discuss.
