您的Apple Watch(Apple Watch)电池可以使用多长时间？如果它似乎耗尽得太快，可能有很多原因，但也有很多方法可以延长电池电量。
Apple Watch电池耗尽可能是正常使用或电池问题造成的，但您必须更多地了解为什么您的 Watch 有时会耗电更多。
您正在使用(Using)更多耗电功能
Apple Watch标称的电池续航时间“最长”18 小时，但这是基于典型使用模式的估计值。如果您是GPS跟踪或锻炼跟踪等功能的重度用户，那么手表(Watch)可能会更快耗尽电量。
在这种情况下， Watch(Watch)实际上并没有任何特别的问题，只是你的用户比一般人重。您可以通过关闭一些对您来说可能不那么重要的功能来管理它。有关禁用个别功能的更多信息，请参阅下面的提示。
您处于极端环境中
Apple Watch设计用于在温度介于 0° 至 35° C（32° 至 95° F）之间的环境中运行。如果您在该范围之外的环境中使用它，它可能会影响电池保持电量的程度。
你的手表太旧了
虽然您的Apple Watch感觉像是一个神奇的设备，但它仍然受到物理和电池化学定律的约束。锂电池(Lithium batteries)会随着时间的推移而失去容量，如果您使用的是Apple Watch的早期型号之一，电池可能已经退化到无法再容纳那么多电量的程度。
Apple Watch中的电池的额定充电周期约为 1000 次，此时它应该还剩下原始容量的 80%。此时您可能想购买新的Apple Watch，但如果您仍然满意，
Apple会以合理的费用为您的手表更换电池。(Apple)
禁用推送通知
任何智能手表最有用的功能之一就是将重要通知直接推送到您的手腕。但是，推送通知会消耗您的电池寿命，因此最好自定义一些内容，以便只有您想要在手表上显示的通知才能通过：
- 按住表盘顶部，直到出现通知。
- 向下滚动(Scroll)，直到找到要修改的通知。
- (Swipe)在通知上向左滑动以显示三个点，然后点击它们。
- 选择(Choose)在特定时间段内将通知静音或永久关闭。
通知越少，手表唤醒的频率就越低，这将有助于延长电池寿命。
更改手表显示(Change Watch Display)和唤醒(Wake)设置
调整显示以获得更长的电池寿命。
- 按(Press)Digital Crown调出应用程序。
- 选择设置。
- 选择显示和亮度。
- 手动降低屏幕亮度以节省电量。
您还可以禁用Wrist Raise Screen(Wake Screen)或Wake on Crown rotation ，这样只需轻按屏幕即可唤醒您的手表(Watch)。确保(Make)唤醒屏幕时间(Wake Screen Time)设置为 15 秒。
更新您的手表操作系统
与 iPhone 或Mac一样，您可以更新Apple Watch上的软件。几乎Watch 系列(Watch Series)的每个重大更新都有一些改进的电源管理功能，因此请将您的手表更新到最新版本的 watchOS 以从优化中受益。
手动检查更新：
- 按(Press)Digital Crown调出应用程序菜单。
- 选择“设置”(Settings)应用（齿轮图标）。
- 选择常规 > 软件更新。
如果您的手表(Watch)有有效的数据连接，它将检查可用的更新。您还应该跟上 iOS 更新，以充分利用这两款Apple设备。
禁用无线功能
Apple Watch使用多种无线技术。如果您有蜂窝网络型号，它具有蜂窝网络、蓝牙(Bluetooth)和Wi-Fi技术。非蜂窝手表当然只有后两种技术。
无线传输会更快地耗尽电池电量，因此通过关闭任何不需要的内部无线电，您可以从设备的电池中挤出更多时间。这三种技术中的每一种都需要单独禁用。
如果您有蜂窝手表，但您并不总是需要该功能，则可以将其关闭。
- (Swipe)从表盘底部向上轻扫。
- 选择手机图标。
- 关闭一个(Toggle one)或两个蜂窝选项。
只要您的手表在手机的蓝牙(Bluetooth)范围内或路由器的Wi-Fi范围内，您就不会失去任何功能，但可以节省电池寿命。如果您远离Wi-Fi并且不需要它，您也可以关闭Wi-Fi：
- (Swipe)从表盘底部向上轻扫。
- 点击 Wi-Fi 图标以打开或关闭它。
最后一种无线技术是蓝牙(Bluetooth)，关闭起来稍微复杂一些：
- 按(Press)Digital Crown调出应用程序屏幕。
- 选择设置 > 蓝牙。
- 关闭蓝牙。
我们不建议关闭蓝牙(Bluetooth)，除非您不会随身携带手机，因为它比蜂窝数据或Wi-Fi更省电。
禁用始终显示
如果您有Apple Watch Series 5或更新机型，则可以访问“始终(Always)显示(Display)”功能。即使您的手腕没有将手表指向您的脸，这也能让您的手表表面可见，让您看一眼时间。
这是一个省电的功能，但打开它仍然比关闭它消耗更多的电量，所以如果你想让你的手表有更多的生命力并且不喜欢这个功能，你可以打开它关了：
- 按下(Press)手表上的数码(Digital Crown)表冠以调出应用程序屏幕。
- 打开设置(Settings)应用程序（齿轮图标）。
- 选择显示和亮度。
- 选择始终开启。
- 关闭该功能。
现在您必须唤醒您的手表才能看到时间，但它会消耗更少的电量。
关闭手表上的应用程序
与 iPhone 或 iPad 一样，您可以手动关闭Watch上的后台应用程序。后台应用(Apps)程序刷新行为不当的应用程序会比平时更快地耗尽电池电量。
- 按下(Press)手表(Watch)的侧面按钮以调出活动应用程序列表。
- 向左滑动(Swipe)您想要关闭的任何应用程序，显示一个红色的 X 按钮。
- 选择 X 关闭应用程序。
与 iOS 设备不同，您无法通过一次操作关闭手表上所有打开的应用程序。相反，您必须单独关闭每个应用程序。
激活电源低功耗模式
watchOS 9 中引入了低功耗模式，取代了旧的(Power Mode)Power Reserve模式。如果您的手表剩余电量超过 10%，您可以手动
激活低电量模式：(Power)
- (Swipe)从表盘底部向上滑动并选择电池百分比。
- 打开低功耗模式
.
- 阅读信息通知，然后选择(For…)打开(Turn)或打开(Turn)...
低功耗(Power)模式会关闭一些使用额外电源的功能：
- 始终显示。
- 心脏相关的通知。
- 心率(Heart)监测和血氧监测。
- 自动锻炼开始提醒。
- Wi-Fi 和蜂窝网络，如果您的 iPhone 不在身边。
- 来电和通知。
除此之外，低功耗(Low Power)模式会降低手表(Watch)的性能。Siri、动画、滚动、后台应用程序和其他一切都可能感觉更迟钝。
如果您有 Series 3 或更旧的Watch，或者尚未更新到 watchOS 9，您仍然必须使用Power Reserve模式。它的激活步骤与上述相同，但它会禁用Watch上的更多功能。
减少屏幕上的运动
您可以通过转到Settings > Accessibility > Reduce Motion来减少手表上动画的运动和复杂性。用户报告说这对电池寿命有显着影响。
解除手机与手表的配对
通常，一旦您完成了Watch和 iPhone 的初始配对，您就再也不用担心了，直到您想要摆脱Watch或换一部新手机。
然而，似乎有些人通过取消配对手表然后再次配对来解决他们的耗电问题。就是这样：
- 将 Watch 置于 iPhone 范围内，打开Apple Watch应用程序。
- 选择我的手表(My Watch)选项卡，然后选择所有手表(Watches)。
- 选择相关手表(Watch)旁边的信息按钮。
- 现在选择取消配对 Apple Watch。
Cellular Watches会询问您是否要保留您的蜂窝计划，因为我们要立即再次配对手表，请确保保留您的蜂窝计划。
按照其余提示进行操作，直到取消配对完成。现在您应该看到开始配对(Start Pairing)提示。选择它并按照说明再次配对您的手表(Watch)。
考虑一下 Apple Watch Ultra
如果您当前的Apple Watch没有任何问题，并且这些优化不足以让您持续使用足够长的时间，那么Apple Watch Ultra可能是您未来的理想选择。
除了一整套高端功能外，Ultra的外形比其他Watch型号更大，并装有更大的电池。它拥有最长 36 小时的最佳Apple Watch电池续航时间，使用特殊设置可以实现更长的运行时间。
一些也适用于 iPhone 的Android智能手表的电池寿命更长，但相比之下功能有所减少。尽管如此，Android型号可能更适合一些需要更多耐用性但又不想为Ultra支付额外费用的(Ultra)Watch用户。
Why Your Apple Watch Dies So Fast (and How to Extend Battery Life)
How long does your Apple Watch battery last? If it seems to run down far too quickly, there could be many reasons, but there are also many ways to extend your battery power.
Apple Watch battery drain could result from normal use or battery issues, but you’ll have to understand a little more about why your Watch uses more power sometimes.
You’re Using Power-Hungry Features More
The stated battery life of an Apple Watch is “up to” 18 hours, but this is an estimate based on typical usage patterns. If you’re a heavy user of features such as GPS tracking or workout tracking, then the Watch may run out of power sooner.
In this case, there aren’t actually any particular issues with the Watch, it’s just that you’re a heavier user than average. You can manage this by turning off some features that may not be as important to you. Refer to the tips below for more information about disabling individual features.
You’re in an Extreme Environment
The Apple Watch is designed to operate in environments with temperatures between 0° and 35° C (32° to 95° F). If you’re using it in an environment outside that range, it could affect how well the battery retains charge.
Your Watch Is Too Old
While your Apple Watch may feel like a magical device, it’s still bound by physics and battery chemistry laws. Lithium batteries lose their capacity over time, and if you’re using one of the earlier models of the Apple Watch, the battery may have degraded to the point where it can no longer hold as much power.
The battery in an Apple Watch is rated for about 1000 full charge cycles, at which point it should have 80% of its original capacity left. You may want to buy a new Apple Watch at this point, but Apple will replace the battery in your watch for a reasonable fee if you’re still happy with it.
Disable Push Notifications
One of the most useful features of any smartwatch is getting important notifications pushed straight to your wrist. However, push notifications eat away at your battery life, so it’s a good idea to customize things so that only notifications you want on your watch make it through:
- Press and hold the top of the watch face until notifications appear.
- Scroll down until you find the notification you want to modify.
- Swipe left on the notification to reveal three dots, then tap on them.
- Choose to mute notifications for a specific period or to turn them off permanently.
With fewer notifications, your watch will wake less often and this will help extend your battery life.
Change Watch Display and Wake Settings
Tweak the display to get more battery life.
- Press the Digital Crown to bring up the apps.
- Select Settings.
- Select Display & Brightness.
- Manually lower the screen brightness to save power.
You can also disable Wake Screen on Wrist Raise or Wake on Crown rotation so only a tap on the screen will wake your Watch. Make sure that Wake Screen Time is set to 15 seconds.
Update Your Watch Operating System
Like an iPhone or a Mac, you can update the software on your Apple Watch. Almost every major update to the Watch Series has some improved power management features, so update your watch to the newest version of watchOS to benefit from the optimization.
To manually check for updates:
- Press the Digital Crown to bring up the app menu.
- Choose the Settings app (the cog icon).
- Choose General > Software update.
If your Watch has an active data connection, it will check for available updates. You should also keep up with iOS updates to get the best out of both Apple devices.
Disable Wireless Features
The Apple Watch uses several wireless technologies. If you have a cellular model, it has cellular, Bluetooth, and Wi-Fi technology. Non-cellular watches, of course, only have the latter two technologies.
Wireless transmissions will drain your battery faster, so by turning off any internal radios you don’t need, you can eke out some more time from the device’s battery. Each of the three technologies needs to be disabled separately.
If you have a cellular Watch, but you don’t need that feature all the time, you can turn it off.
- Swipe up from the bottom of the watch face.
- Select the cellular icon.
- Toggle one or both of the cellular options off.
As long as your Watch is within Bluetooth range of your phone or Wi-Fi range of your router, you won’t lose any functionality, but you may save battery life. If you’re away from Wi-Fi and don’t need it, you can turn off Wi-Fi as well:
- Swipe up from the bottom of the watch face.
- Tap the Wi-Fi icon to toggle it on or off.
The last wireless technology is Bluetooth, which is a little more complicated to turn off:
- Press the Digital Crown to bring up the app screen.
- Select Settings > Bluetooth.
- Toggle Bluetooth off.
We don’t recommend turning off Bluetooth unless you won’t have your phone with you, since it’s more power-efficient than cellular data or Wi-Fi.
Disable the Always On Display
If you have an Apple Watch Series 5 or later, you can access the Always On Display feature. This keeps your watch face visible even when your wrist is not pointing the watch towards your face, allowing you to glance at the time.
This is a power efficient feature, but it still does use a little more power to have it on than to have it off, so if you want to get more life out of your watch and don’t care for this feature, you can turn it off:
- Press the Digital Crown on your Watch to bring up the app screen.
- Open the Settings app (the gear icon).
- Select Display & Brightness.
- Select Always On.
- Toggle the feature off.
Now you’ll have to wake your Watch to see the time, but it will consume less power.
Close Apps On Your Watch
As with an iPhone or iPad, you can manually close background apps on your Watch. Apps with misbehaving background app refresh behavior can drain your battery more quickly than usual.
- Press the side button of the Watch to bring up the list of active apps.
- Swipe any app you want to close to the left, revealing a red X button.
- Select the X to close the app.
Unlike iOS devices, you can’t close all the open apps on your Watch in a single operation. Instead, you’ll have to close each app individually.
Activate Power Low Power Mode
Low Power Mode was introduced in watchOS 9 and replaced the older Power Reserve mode. If your Watch has more than 10% battery left, you can activate Low Power mode manually:
- Swipe up from the bottom of your watch face and select the battery percentage.
- Toggle Low Power mode on
.
- Read the information notice, and select Turn On or Turn On For…
Low Power mode turns off a number of features that use additional power:
- Always On Display.
- Heart-related notifications.
- Heart rate monitor and blood oxygen monitoring.
- Automatic workout start reminder.
- Wi-Fi and Cellular, if away from your iPhone.
- Calls and notifications.
Apart from this, Low Power mode reduces the performance of your Watch. Siri, animations, scrolling, background apps, and everything else may feel more sluggish.
If you have a Series 3 or an older Watch, or haven’t updated to watchOS 9, you’ll still have to use Power Reserve mode. It’s activated with the same steps as above, but it disables far more features on the Watch.
Reduce On-screen Motion
You can reduce the motion and complexity of animations on the Watch by going to Settings > Accessibility > Reduce Motion. Users report that this has a noticeable effect on battery life.
Unpair Your Phone and Watch
Usually, once you’ve completed the initial pairing of your Watch and iPhone, you’ll never have to worry about it again until you want to get rid of the Watch or get a new phone.
However, it seems that some people have solved their power drain issues by unpairing their Watch and then pairing it again. Here’s how:
- With your Watch in range of your iPhone, open the Apple Watch app.
- Select the My Watch tab, then All Watches.
- Select the info button next to the Watch in question.
- Now select Unpair Apple Watch.
Cellular Watches will ask you if you want to keep your cellular plan, since we want to pair the watch immediately again, make sure to keep your cellular plan.
Follow the rest of the prompts until unpairing is complete. Now you should see the Start Pairing prompt. Select it and follow the instructions to pair your Watch again.
Consider the Apple Watch Ultra
If there’s nothing wrong with your current Apple Watch and these optimizations don’t make it last long enough for you, the Apple Watch Ultra might be a good future purchase.
Apart from a whole raft of high-end features, the Ultra is physically larger than the other Watch models and packs a larger battery. It has the best Apple Watch battery life at up to 36 hours, with even longer run times possible using special settings.
Some Android smartwatches that also work with iPhone have longer battery lives, but reduced features in comparison. Still, an Android model may be a better fit for some Watch users who need more endurance, but don’t want to pay the premium for the Ultra.
