无论您是刚买了一台全新的笔记本电脑(new laptop)，还是已经使用了一段时间，让笔记本电脑电池保持良好状态并延长运行时间非常重要。
与现代笔记本电脑相比，旧笔记本电脑相形见绌，这要归功于技术进步使现代笔记本电脑(modern laptops)具有更长的电池寿命、性能和效率。尽管如此，您仍需要插入功能强大的笔记本电脑，以使其全天保持活力。
了解延长笔记本电脑电池寿命的选项。
如何增加笔记本电脑的电池寿命 (How to Increase Laptop Battery Life )
通过一些软件和硬件调整，可以延长笔记本电脑的电池寿命，这样您就不必经常紧急冲向电源插座。
快速提示(Quick Tips)
- 调整屏幕亮度(Adjust screen brightness)，因为屏幕使用大量电池电量来保持显示屏明亮清晰。
- 关闭蓝牙(Bluetooth)和WiFi，直到您需要它为止。即使您已连接，这些也会通过搜索附近的无线网络和连接来消耗电池电量。
- 如果您的任务不需要 Web 访问，请启用飞行模式。(Airplane Mode)这通过在您执行单一任务时关闭无线电、后台应用程序和其他程序来消除电池消耗。
- 拔下或关闭USB 记忆棒(USB sticks)、网络摄像头或鼠标等外围设备，这些外围设备可能会耗尽您的笔记本电脑，因为主板必须为其供电。例如，您可以使用笔记本电脑的触控板，而不是使用USB鼠标。(USB)
- (Mute)如果您不需要声音，请将您的笔记本电脑扬声器静音，因为它还会在每次 Windows 启动或收到电子邮件和其他通知时耗尽您的笔记本电脑电池
- 如果您的笔记本电脑安装了磁盘驱动器，请确保在切换到电池电源之前它是空的。笔记本电脑中的转盘会在您工作时消耗笔记本电脑电池所需的重要额外时间。
- 在电池没电之前插入笔记本电脑，以避免电池紧张并降低其充电容量。同样，如果您的笔记本电脑没有优先考虑电池健康的智能充电模式，则您无需一直插电，因为这可能会减少充电周期数( reduce the number of charging cycles)。
- 在环境温度较高的区域使用您的笔记本电脑，因为过度暴露在极端温度下会导致计算机更加努力地工作，并最终损坏或缩短电池的使用寿命
- 如果您有一台较旧的Mac笔记本电脑，请确保电池已校准，以便更容易预测剩余电量或电量何时用完。
确保您的笔记本电脑有足够的 RAM(Make Sure Your Laptop Has Enough RAM)
有了足够的RAM，您的笔记本电脑就可以比存储在硬盘驱动器上更快地执行各种任务并检索数据。这使您的硬盘驱动器无法正常运行，并延长了笔记本电脑的电池寿命。
或者，将您的硬盘换成固态硬盘(solid state drive)( SSD )。SSD在闪存上运行，并且比 HDD 使用更少的电力来运行(HDD)。此外，您可以更快地访问文件，计算机运行速度也会更快，从而节省笔记本电脑的电池寿命。
关闭耗电应用(Close Power Hogging Apps)
检查在后台运行的应用程序(apps running in the background)是否可以更快地消耗电池寿命，尤其是那些您没有积极使用的应用程序。
您可以在任务管理器(Task Manager)中检查此类应用程序。右键单击(Right-click)任务栏，选择任务管理器(Task Manager)，然后在“启动(Startup)”选项卡下检查任何耗电最多的实用程序。
如果您使用的是Mac笔记本电脑，请搜索Users & Groups，选择Login Items选项卡，然后在您启动笔记本电脑时查看当前在后台运行的应用程序。
使 Windows 保持最新状态(Keep Windows Up to Date)
Windows 更新(Windows Updates)可能很烦人，但它们是改进使用笔记本电脑电源的程序的好方法。操作系统补丁或错误修复可以帮助您的笔记本电脑使用更少的电池电量并延长电池寿命。
获取笔记本电脑移动电源(Get a Laptop Power Bank)
增加笔记本电脑电池寿命的另一种方法是手头有一块额外的电池，或者买一个笔记本电脑移动电源(power bank)。
笔记本电脑移动电源是一种紧凑的电池单元，其便携性足以放入您的背包或笔记本电脑包中，并且可以增加您的充电时间。此外，备用电池以与充电器相同的方式插入笔记本电脑，并附带一个适配器，可用于不同的笔记本电脑型号。
一些不错的型号包括 Anker PowerCore+ 26800、 Omni 20+ Wireless Power Bank和 MAXOAK 185Wh/50000mAh Battery Pack。
调整电源设置(Adjust Power Settings)
调整笔记本电脑上的电源设置可确保您在未插入电源时优化电池寿命。
- 为此，请在搜索框中输入电源选项，然后选择(Power Options)电源和睡眠设置(Power & Sleep Settings)。
- 检查电源设置并选择可以为您节省更多电池电量的选项。
或者，使用Windows 10电池性能滑块中的省电(Battery Saver)模式。这两个类别通过暂停大多数后台应用程序、阻止Windows 更新(Windows Updates)下载和降低亮度来提供更长的电池寿命。
对于Mac笔记本电脑，没有电池性能滑块，但您可以在“节能器”首选项(Energy Saver preferences)部分调整设置。
调整图形和显示设置(Adjust Graphics and Display Settings)
如果您的笔记本电脑具有强大的显卡(powerful graphics card)，请调整图形设置，以便只有游戏和照片或视频编辑应用程序可以使用它，并将其他所有内容分配给集成芯片。
对于Mac笔记本电脑，请检查节能器设置下的(Energy Saver)自动(Automatic)图形切换选项。这样，您的Mac将确定哪个应用程序使用哪个图形加速器来延长电池寿命。
延长笔记本电脑的电池寿命(Extend Your Laptop’s Battery Life)
对于大多数使用笔记本电脑花费数小时远离电源的移动笔记本电脑用户来说，电池寿命和性能是一个主要问题。
虽然现代笔记本电脑一次充电可以运行数小时，但运行时间可能并不总是足以满足您的需求。通过这些技巧，您可以延长笔记本电脑的电池寿命并延长运行时间。
我们很想听听您使用哪些技巧来延长笔记本电脑的电池寿命。在评论中与我们分享。
How to Increase Battery Life on a Laptop
Whether you’vе just bought a brand new laptop or you’ve had yours for a while, it’s important to keep your laptop battery in good shape and running longer.
Older laptops pale in comparison to modern ones thanks to technological advancements that give modern laptops greater battery life, performance, and efficiency. Still, you’ll need to plug in your powerful laptop to keep it juiced up throughout the day.
Learn about the options you have to increase battery life on a laptop.
How to Increase Laptop Battery Life
With a few software and hardware tweaks, it’s possible to squeeze longer battery life out of your laptop so you won’t have to make an urgent dash to a power outlet too often.
Quick Tips
- Adjust screen brightness, as the screen uses copious amounts of battery power to keep your display bright and clear.
- Switch off Bluetooth and WiFi until you need it. These drain the battery by searching for nearby wireless networks and connections even when you’re connected.
- Enable Airplane Mode if your task doesn’t need web access. This eliminates battery drain by shutting down wireless radios, background apps and other programs as you single-task.
- Unplug or turn off peripherals such as USB sticks, webcams, or mice, which can drain your laptop because the motherboard has to power them. For example, instead of using a USB mouse, you can use your laptop’s trackpad instead.
- Mute your laptop speakers if you’ve no need for sound as it can also drain your laptop battery each time Windows boots or when you receive an email and other notifications
- If your laptop came with a disc drive installed, make sure it’s empty before switching to battery power. Spinning discs in your laptop drain the vital extra minutes you need from your laptop battery as you work.
- Plug in your laptop before the battery dies to avoid straining the battery and reducing its charging capacity. Similarly, if your laptop doesn’t have a smart charging mode that prioritizes battery health, you don’t need to keep it plugged in all the time as this may reduce the number of charging cycles.
- Use your laptop in areas with ambient temperature as excessive exposure to extreme temperatures cause the computer to work harder, and eventually damage or shorten the battery’s useful life
- If you have an older Mac laptop, make sure the battery is calibrated so it’s easier to predict the remaining charge or when that charge will be used up.
Make Sure Your Laptop Has Enough RAM
With adequate RAM, your laptop can perform various tasks and retrieve data faster than when it’s stored on the hard drive. This keeps your hard drive from operating as much and increases battery life on your laptop.
Alternatively, swap out your hard drive for a solid state drive (SSD). An SSD operates on flash memory and uses less power to operate than an HDD would. Plus, you’ll access files more quickly and your computer will run faster, in turn saving laptop battery life.
Close Power Hogging Apps
Check for apps running in the background that chew battery life faster, especially those that you’re not actively using.
You can check for such apps in the Task Manager. Right-click on the taskbar, select Task Manager, and check under the Startup tab for any utility that’s consuming the most power.
If you’re using a Mac laptop, search for Users & Groups, select the Login Items tab, and see the apps currently running in the background when you start up your laptop.
Keep Windows Up to Date
Windows Updates can be annoying but they’re a good way of improving the programs that use power on your laptop. An operating system patch or bug fix may help your laptop use less battery power and increase the battery lifespan.
Get a Laptop Power Bank
Another way to increase battery life on laptops is to keep an extra battery at hand, or get a laptop power bank.
A laptop power bank is a compact battery unit that’s portable enough to place in your backpack or laptop bag, and can increase the length of your charge. Plus, the battery backup plugs into your laptop the same way your charger would, and comes with an adapter you can use with different laptop models.
Some good models include the Anker PowerCore+ 26800, Omni 20+ Wireless Power Bank, and MAXOAK 185Wh/50000mAh Battery Pack.
Adjust Power Settings
Adjusting power settings on your laptop ensures that you optimize battery life when you’re not plugged into the mains.
- To do this, type Power Options in the search box and select Power & Sleep Settings.
- Check the power settings and select the options that will give you greater battery savings.
Alternatively, use the Battery Saver mode in the Windows 10 battery performance slider. Both categories deliver longer battery life by suspending most background apps, preventing Windows Updates downloads and reducing brightness.
For Mac laptops, there’s no battery performance slider, but you can adjust the settings in the Energy Saver preferences section.
Adjust Graphics and Display Settings
If your laptop has a powerful graphics card, adjust the graphics settings so that only the games and photo or video editing apps can use it, and assign everything else to the integrated chip.
For Mac laptops, check the Automatic graphics switching option under the Energy Saver settings. This way, your Mac will determine which app uses which graphic accelerator to conserve battery life.
Extend Your Laptop’s Battery Life
For most mobile laptop users who spend hours away from power with their laptops, battery life and performance are a major concern.
While modern laptops can run many hours on a single charge, the runtime may not always be enough for your needs. With these tips, you can increase battery life on your laptop and extend that runtime.
