MacBook(MacBooks)具有出色的电池续航时间，通常一次充电即可使用一整天的中度到重度使用。尽管如此，重要的是要定期查看剩余电量，因为密集型任务和未优化的应用程序会很快耗尽电池电量(drain the battery quickly)。然而， macOS Big Sur并没有那么容易。
如果您刚刚从 macOS Catalina升级，您会立即注意到 Mac 菜单栏上缺少电池百分比指示器。有熟悉的电池图标，但这并不能提供准确的图片，并且经常会误导您。
(Show Battery Percentage)在 macOS Big Sur中(Big Sur)显示电池百分比
尽管从菜单栏中删除了电池百分比指示器，macOS Big Sur确实允许您以百分比形式检查剩余电量。选择电池图标(battery icon)以调出电池状态(Battery Status)菜单，您将在第一行看到信息。不过，这不是您想要一直重复的事情。
幸运的是，您仍然可以在 Mac 的菜单栏上重新设置百分比指示器。在 macOS Catalina及更早版本中，“电池状态”(Battery Status)菜单包含一个“显示百分比”(Show Percentage)开关，可让您轻松启用和禁用该功能。但是，macOS Big Sur已将其深埋在“系统偏好设置”(System Preferences)窗格中。
这是在 macOS Big Sur(Big Sur)的菜单栏上显示电池百分比的方法。
1. 打开Apple 菜单(Apple menu)并选择系统偏好设置(System Preferences)。
2. 选择标记为Dock & Menu Bar的选项。
3.向下滚动(Scroll)左侧边栏并选择电池(Battery)。
4. 选中显示百分比(Show Percentage)旁边的框。
电池百分比指示器应立即显示在 Mac 菜单栏上电池图标的左侧。
有第三方应用程序可以帮助您在菜单栏中添加更多与电池相关的详细信息——我们将在下面进一步介绍一个列表。
macOS Big Sur(Big Sur)中其他与电池相关的添加和更改
macOS Big Sur带有一个类似 iPhone 的控制中心，它将(Control Center)蓝牙(Bluetooth)、Wi-Fi和请勿打扰(Disturb)等选项组合在一起。这有助于减少菜单栏上的混乱。
如果需要，您可以将电池图标和百分比指示器添加到控制中心(Control Center)。为此，请选中System Preferences > Dock & Menu Bar > Battery中的(Battery)Show in Control Center选项。您还可以取消选中在菜单栏中显示(Show in Menu Bar)以将它们从菜单栏中删除。
此外，macOS Big Sur摒弃了Catalina 的节能器偏好(Energy Saver preferences from Catalina)设置，取而代之的是一个专用的“电池(Battery)”面板——您可以通过从“电池状态”(Battery Status)菜单中选择“电池偏好设置”来调出它。(Battery Preferences)它提供过去 24 小时和 10 天与电池相关的使用统计数据，与 iPhone 类似。
您还可以通过在“电池(Battery)”首选项窗格中的“电池(Battery)” 、“电源适配器(Power Adapter)”和“计划”侧(Schedule side )选项卡之间切换来访问旧的节能器(Energy Saver)设置（睡眠(Sleep)、电源小睡(Power Nap)等） 。
(Apps)显示电池百分比(Battery Percentage)和剩余时间的(Time Remaining)应用程序
第三方电池应用程序不仅可以在 macOS Big Sur的菜单栏上显示电池百分比，还可以提供对更多电池相关信息的快速访问。以下是三个值得仔细研究的程序：
注意：(Note:)如果您决定使用这些应用程序中的任何一个，您可以随时禁用备用电池图标和百分比指示器，以避免 Mac 菜单栏上的额外混乱。
椰子电池(coconutBattery)
椰子电池可以深入了解Mac Book 电池的状况。它显示循环计数、健康状态、温度、完全充电和设计容量、制造日期等。将 iPhone 或 iPad连接(Connect)到您的Mac，您还可以通过切换到iOS 设备(iOS Device )选项卡来获得一组类似的详细信息。
此外，您可以将椰子电池直接粘贴在菜单栏上。打开椰子电池首选项(Preferences)，切换到常规选项卡并选中(General )在后台运行椰子电池(Run coconutBattery in background and show information in Menu Bar)旁边的框并在菜单栏中显示信息。
默认情况下，conceptBattery 会在菜单栏中添加一个百分比指示器。相反，您可以通过将相关参数插入“格式(Format)”字段来使其显示剩余时间、充电周期、瓦特使用量等——它旁边的图标显示了它们的列表。
此外，如果您希望电池图标出现在百分比指示器旁边（或您配置的任何其他显示） ，请选择显示充电图标。(Show charge icon)
将椰子电池添加到菜单栏后，您可以选择它以菜单格式查看其他电池信息（如剩余时间、温度、循环计数等）。
电池医生(Battery Medic)
Battery Medic直接在 Mac 的菜单栏中启动，并默认显示彩色电池图标和百分比指示器。选择该图标，您可以查看大量额外信息，例如剩余时间、电池健康状况、充电周期等。
如果需要，您可以将剩余电池时间添加到菜单栏本身。打开Battery Medic菜单，选择Preferences ，然后选中(Preferences)Show Battery Time旁边的框。
此外，您可以选择在电池电量达到上限或下限阈值时使用低电量通知(Low battery notification)和电池电量充足通知下方的滑块接收通知(Full battery notification)。
简单的电池监视器(Simple Battery Monitor)
顾名思义，Simple Battery Monitor比椰子电池和Battery Medic简单得多。它会在MacBook(MacBook)的菜单栏上显示电池状态图标、百分比指示器和剩余时间。您还可以选择它以快速查看充电周期数，仅此而已。
就自定义而言，您可以使用简单电池监视器的设置(Settings)子菜单中的显示百分比切换来选择禁用或启用百分比指示器。(Show Percentage)
准确性很重要，Apple
从视觉上看，macOS Big Sur比其前辈更加一致且不那么混乱。不过(Though)，Apple移除了电池百分比指示器，走得太远了。但正如您刚刚发现的那样，您无需做太多事情即可将其取回。也就是说，如果您投资于延长 Mac 的电池寿命，则可以使用椰子电池或(extending your Mac’s battery life)Battery Medic等应用程序访问更多与电池相关的信息。
How to Show Battery Percentage in macOS Big Sur
MacBooks offer outstanding battery life and υsually allow for an entire day’s worth of moderate to heavy use on a single charge. Still, it’s important to keep regular tabs on the amount of charge remaining since intensive tasks and unoptimizеd аpps can drain the battery quickly. macOS Big Sur, however, doesn’t make that easy.
If you just upgraded from macOS Catalina, you would’ve immediately noticed the missing battery percentage indicator on the Mac’s menu bar. There’s the familiar battery icon, but that doesn’t provide an accurate picture and can often mislead you.
Show Battery Percentage in macOS Big Sur
Despite removing the battery percentage indicator from the menu bar, macOS Big Sur does allow you to check the remaining charge in percentage terms. Select the battery icon to bring up the Battery Status menu, and you will see the information in the first row. It’s not something that you’d want to repeat all the time, though.
Luckily, you can still go back to having a percentage indicator on the Mac’s menu bar itself. In macOS Catalina and earlier, the Battery Status menu included a Show Percentage toggle that allowed you to enable and disable the feature easily. But, macOS Big Sur has buried it deep within the System Preferences pane.
Here’s how to show battery percentage on the menu bar in macOS Big Sur.
1. Open the Apple menu and select System Preferences.
2. Select the option labeled Dock & Menu Bar.
3. Scroll down the sidebar to the left and select Battery.
4. Check the box next to Show Percentage.
The battery percentage indicator should immediately show up to the left of the battery icon on the Mac’s menu bar.
There are third-party apps that can help you add even more battery-related details to the menu bar—we’ll go through a list further below.
Other Battery-related Additions and Changes in macOS Big Sur
macOS Big Sur comes with an iPhone-like Control Center that groups together options such as Bluetooth, Wi-Fi, and Do Not Disturb. That helps cut down the clutter on the menu bar.
If you want, you can add the battery icon and percentage indicator to the Control Center. To do that, check the Show in Control Center option within System Preferences > Dock & Menu Bar > Battery. You can also uncheck Show in Menu Bar to remove them from the menu bar.
Additionally, macOS Big Sur ditches the Energy Saver preferences from Catalina and instead comes with a dedicated Battery pane—you can bring it up by selecting Battery Preferences from the Battery Status menu. It provides battery-related usage stats for the past 24 hours and 10 days, again similar to the iPhone.
You can also access the older Energy Saver settings (Sleep, Power Nap, etc.) by switching between the Battery, Power Adapter, and Schedule side tabs in the Battery preferences pane.
Apps to Show Battery Percentage and Time Remaining
Third-party battery apps can not only show the battery percentage on the menu bar in macOS Big Sur, but they can also provide quick access to even more battery-related information. Here are three such programs that deserve a closer look:
- Coconut Battery
- Battery Medic
- Simple Battery Monitor
Note: If you decide to go for any of these apps, you can always disable the stock battery icon and percentage indicator to avoid extra clutter on the Mac’s menu bar.
coconutBattery gives a lot of insight into the condition of a MacBook’s battery. It displays the cycle count, health status, temperature, full charge and design capacities, manufacture date, and so on. Connect an iPhone or an iPad to your Mac, and you can also get a similar set of details by switching to the iOS Device tab.
Additionally, you can stick coconutBattery right up on the menu bar itself. Open the coconutBattery Preferences, switch to the General tab and check the box next to Run coconutBattery in background and show information in Menu Bar.
By default, coconutBattery adds a percentage indicator to the menu bar. Instead, you can make it display the time remaining, charge cycles, watt usage, etc., by inserting the relevant parameters into the Format field—the icon next to it reveals a list of them.
Also, select Show charge icon if you want a battery icon to appear alongside the percentage indicator (or whatever else you’ve configured to show up).
After adding coconutBattery to the menu bar, you can select it to view additional battery information (such as time remaining, temperature, cycle count, etc.) in menu format.
Battery Medic launches directly within the Mac’s menu bar itself and displays a colored-battery icon and a percentage indicator by default. Select the icon, and you can view lots of extra information such as the time remaining, battery health, charge cycles, and so on.
If you want, you can add the amount of battery time remaining into the menu bar itself. Open the Battery Medic menu, select Preferences, and check the box next to Show Battery Time.
Additionally, you can choose to receive notifications whenever the battery’s charge level reaches an upper or a lower threshold using the sliders underneath Low battery notification and Full battery notification.
As its name implies, Simple Battery Monitor is much simpler compared to coconutBattery and Battery Medic. It displays a battery status icon, a percentage indicator, and the amount of time remaining on the menu bar of your MacBook. You can also select it to get a quick peek at the number of charge cycles, but that’s about it.
As far as customization goes, you can choose to disable or enable the percentage indicator using the Show Percentage toggle within the Simple Battery Monitor’s Settings sub-menu.
Accuracy Does Matter, Apple
Visually, macOS Big Sur is more consistent and less cluttered than its predecessors. Though, Apple went too far by removing the battery percentage indicator. But as you just found out, you don’t have to do much to get it back. That said, having access to more battery-related information with an app such as coconutBattery or Battery Medic is the way to go if you’re invested in extending your Mac’s battery life.
