管理电池使用是电子设备最重要的方面，以保护电池的性能并延长电池寿命。此外，Windows 11/10不断升级，增加了新的功能来简化电池寿命的管理。虽然不断升级似乎显着提高了整体电池寿命，但一些用户报告了电池耗尽问题。在电池消耗方面，显示亮度和处理器是消耗大量电池电量的因素。此外，涉及硬件处理的复杂任务最终会耗尽您的电池寿命。
(Battery)Windows笔记本电脑中的电池消耗问题
在我们讨论解决这些电池耗尽问题的一些解决方案之前，我们建议您拔下连接到系统的附件。此外，尝试减少启动程序(reduce your startup programs)并关闭所有可有可无的程序并降低屏幕亮度，这可能有助于延长电池寿命。除了这些提示之外，您可能还需要查看以下解决方案来延长电池的使用寿命。
1]打开省电模式
有时，系统更新后，可能会关闭省电模式，您需要手动打开省电模式。省电(Battery)模式允许用户控制电池电量消耗，以获得最长的开机时间。通过启用省电模式，您的系统将自动限制在后台运行的所有应用程序。要启用省电模式，请执行以下步骤：
视窗 11
首先，右键单击任务栏上的(Taskbar)开始(Start)按钮，然后从其中显示的选项列表中选择设置。或者，您可以使用Win+I键盘快捷键直接进入设置窗口。
接下来，从左侧的侧面板中选择系统。(System)
在右侧，移至电源和电池(Power & battery)设置。展开其设置并向下滚动到电池(Battery)部分。
在那里，点击电池保护(Battery saver)条目旁边的下拉按钮。
单击输入时自动打开电池保护程序(Turn battery saver on automatically at )旁边的下拉菜单，然后从显示的选项列表中选择所需的选项。
检查应用程序的电池(Battery)使用情况 Windows 11
在电池(Battery)部分下，就在省电(Battery saver)模式设置下方，点击电池使用量(Battery usage)下拉按钮。然后，在每个应用的电池使用情况(Battery usage per app)下，检查消耗更多电量的应用。
单击菜单(Menu)（显示为 3 个垂直点），选择管理后台活动(Manage background activity)并关闭相机(Camera)、位置(Location)等的应用(App)权限。
视窗 10
转到设置并单击系统。
单击(Click)系统(System)窗口左侧的电池选项。(Battery)
找到省电模式(Battery Saver)设置并切换设置 -如果我的电池电量低于 ，则自动打开省电模式(Turn on battery saver on automatically if my battery falls below)。将滑块移动到合适的位置。
2]检查应用程序的电池使用情况
要了解每个应用程序的电池使用情况，请按照以下步骤操作。
在电池设置中， 单击(Click)选项“应用程序的电池使用情况(Battery Usage by app)”。
“应用程序的电池(Battery)使用情况”窗口显示所有应用程序和电池消耗百分比。
确定您认为正在使用非常高功率的应用程序，并查看您是否要限制使用、禁用或删除应用程序。
3]使用睡眠研究工具(Use Sleep Study Tool)找出是什么耗尽了你的电池
Windows Sleep Study Tool是Microsoft的一款新工具，可帮助您了解在支持(Microsoft)Windows 10/8.1 InstantGo的计算机中究竟是什么消耗了您的电池电量。
4]使用PowerCfg解决电源(Troubleshoot Power)问题
PowerCfg是一个命令实用工具，它将扫描您的计算机 60 秒以了解系统的电源效率并跟踪所有耗尽电池寿命的问题。该工具以HTML(HTML)报告的形式提供详细的结果，以便您可以实际评估电池耗尽的原因。通过这种方式，您可以采取必要的措施来延长电池寿命。按照以下步骤生成电源报告并评估系统的效率。
以管理员身份运行命令提示符(Run Command Prompt)并执行以下命令：
powercfg/energy
这将生成一份详细的HTML报告，您可以在其中检查错误。
要生成完整的电池运行状况报告，请在命令提示符中键入以下命令：
powercfg/batteryreport
点击输入。
这将提供有关电池问题、充电额定值、电池使用历史和电池充电周期历史的详细HTML报告。(HTML)
您还可以运行此命令来确定设置的设备，以便用户可以使用以下命令唤醒计算机并关闭它们：
powercfg –devicequery wake_armed
有关PowerCFG选项的更多信息，请运行POWERCFG /?命令在提升的提示符下。
5]运行电源故障排除程序
运行电源故障排除程序，让它检查并自动检测和修复电源(Power)问题。
6]通过定制的电源(Power)计划延长电池寿命(Extend Battery)
电源计划有助于节省能源，同时最大限度地提高系统性能。它基本上使您能够在电池寿命和性能之间进行优先排序。它们让您可以通过在系统处于睡眠模式或充电模式或系统插入电源时规划和调整屏幕亮度来自定义电池使用情况。您可以在系统开启时更改显示、亮度和睡眠设置电池或系统插入电源时。此外，您可以更改高级电源设置或恢复到默认设置。以下步骤将指导您使用电源计划。
转到控制面板(Control Panel)，然后单击电源(Power)选项。
在电源选项中，选择创建电源计划(Create a Power plan)。现在您将能够根据需要创建电源计划。
如果上述解决方案对您不起作用，请检查您的驱动程序是否已更新。大多数时候，过时的驱动程序会消耗大量电池，因此更新驱动程序以最大限度地延长设备电池寿命并防止发生其他与系统相关的问题非常重要。
省电模式可以在 PC 上使用吗？
是的！当您启用省电功能时，它会阻止在后台运行的应用程序。用户仍然可以允许特定的单个应用程序在节电模式下运行。在Windows中，您可以选择在电池电量达到一定百分比时启用省电模式。
Windows 省电模式有多好？
它真的很好用。该设置会自动调暗显示器的亮度。这是一个最有用但很少使用的技巧，可以节省每台设备的电池寿命。此外，该模式会限制当前未使用的后台应用程序，即使它们是桌面应用程序也是如此。

Additionally, the complex task that involvеs hardwаre processing will eventually drain your battery life.
Battery drain issues in Windows laptop
Before we talk about some solutions to fix these battery drain problems, we suggest you unplug the accessories connected to the system. Also, try to reduce your startup programs and close all the dispensable programs and lower screen brightness that may assist in boosting the battery life. Apart from these tips, you may want to check out the following solutions to elevate the life of a battery.
1] Turn on the Battery Saver Mode
Sometimes, after a system update, the battery saver mode may be toggled off, and you need to turn on the battery saver manually. The Battery saver mode allows users to control battery power consumption in order to have maximum on-time. By enabling the battery saver mode, your system will automatically restrict all the applications that are running in the background. To enable Battery Saver Mode, follow these steps:
Windows 11
First, right-click the Start button on the Taskbar and choose Settings from the list of options displayed therein. Alternatively, you can use Win+I keyboard shortcut to go to the settings window directly.
Next, select System from the side panel on the left.
On the right, Move to Power & battery settings. Expand its settings and scroll down to Battery section.
There, hit the drop-down button next to Battery saver entry.
Click the drop-down menu adjacent to Turn battery saver on automatically at entry and from the list of options displayed, select the desired option.
Check Battery usage by apps Windows 11
Under Battery section, just below Battery saver settings, hit the Battery usage drop-down button. Then, under Battery usage per app, check the apps consuming more power.
Click the Menu (visible as 3 vertical dots), choose Manage background activity and turn off App permissions for Camera, Location, etc.
Windows 10
Go to Settings and click on System.
Click on the Battery option on the left side of the System window.
Locate the Battery Saver settings and toggle the setting – Turn on battery saver on automatically if my battery falls below. Move the slider to a suitable position.
2] Check Battery usage by apps
To find out the battery usage of each app follow these steps.
In the battery settings, Click on the option ‘Battery Usage by app‘.
The ‘Battery usage by app’ window is displayed with all the apps and the percentage of battery consumptions.
Identify the ones you think are using very high power, and see if you would like to restrict usage, disable, or remove the app/s.
3] Use Sleep Study Tool to find out what drains your battery
Windows Sleep Study Tool is a new tool from Microsoft that helps you study what exactly is draining your battery power in a Windows 10/8.1 InstantGo supported computer.
4] Troubleshoot Power problems with PowerCfg
PowerCfg is a command utility tool that will scan your computer for 60 seconds to know the power efficiency of your system and tracks all the issues that are draining the battery life. The tool provides detailed results in the form of an HTML report so that you can actually evaluate the cause of battery drain. In this way, you can take the necessary steps to extend battery life. Follow these steps to generate a power report and evaluate the efficiency of your system.
Run Command Prompt as administrator and execute the following command:
powercfg/energy
This will generate a detailed HTML report which you can check for errors.
To generate a complete battery health report type the following command in the command prompt:
powercfg/batteryreport
Hit Enter.
This will give a detailed HTML report on battery issues, charge ratings, history of battery use and history of battery charge periods.
You can also run this command to determine the devices that are set so that the user can wake the computer and turn them off by using the following command:
powercfg –devicequery wake_armed
For more information about the PowerCFG options, run POWERCFG /? command in an elevated prompt.
5] Run Power Troubleshooter
Run the Power Troubleshooter and let it check for and automatically detect and fix Power issues.
6] Extend Battery life with customized Power Plans
Power plans help conserve energy while you maximize the system performance. It basically gives you the power to prioritize between battery life and performance. They let you customize the battery usage by planning and adjusting the screen brightness either when the system is in sleep mode or charging mode or when the system is plugged in. You can change the settings of display, brightness and sleep either when the system is on battery or when the system is plugged in. Moreover, you can change advanced power settings or restore to the default settings. The following steps will guide you in using power plans.
Go to Control Panel and click on Power options.
In the Power Options, choose to Create a Power plan. Now you will be able to Create a Power plan as per your needs.
If the above solution doesn’t work for you, check if your drivers are updated. Most of the time, outdated drivers consume a lot of battery, so it is important to update the drivers to maximize device battery life as well as prevent other system-related problems from happening.
Does Battery Saver work on PC?
Yes! When you enable battery saver feature, it blocks apps running in the background. Users can still allow specific individual apps to run while in battery saver mode. In Windows, you can choose to enable battery saver when the battery level reaches a certain percentage.
How good is Windows Battery Saver?
It works really well. The setting automatically dims your display’s brightness. It’s one most useful but rarely used trick that can save battery life on every single device. In addition, the mode throttles background apps not in use currently, even if they’re desktop apps.
