尽管Apple Watch是最准确的腕戴式健身追踪设备之一，但它有时会给出不准确的读数。如果您遇到此问题，我们将向您展示如何校准Apple Watch以获得更好的健身追踪。
我们还将介绍其他必要的调整，以实现更准确的锻炼测量。我们还将向您展示如何在Apple Watch上重置健身追踪校准。
更新(Update Health Data)Apple Watch的健康数据
有时，不准确的Apple Watch健身追踪是由健康数据引起的。如果您的健康详细信息（例如身高、体重、年龄或性别）不正确，您可能会在健身追踪中看到错误。
要解决此问题，请在 iPhone 上打开Apple Watch应用，然后点击屏幕底部的“我的手表”标签。(My Watch)现在向下滚动，转到Health > Health Details，然后点击屏幕右上角的
Edit按钮。(Edit)
您现在可以点击此页面上的每个健康详细信息并更正任何不准确之处。正确输入您的健康数据后，您的Apple Watch将能够为您提供更准确的心率测量和卡路里消耗数据(calorie burn data)。
请注意，您只能将Apple Watch与 iPhone 配对，因此您只需要这两台设备即可进行健身追踪校准。您无法将Apple Watch与Mac、iPad 或Apple生态系统中的大多数其他产品配对。
更改(Change)iPhone权限(Permissions)以提高 Apple Watch 跟踪准确性(Improved Apple Watch Tracking Accuracy)
在我们谈论校准之前，您必须检查您的 iPhone 的权限以帮助校准您的Apple Watch。在 iPhone 上，打开设置(Settings)，点击隐私(Privacy)，然后点击定位(Location) 服务(Services)。在下一页上，确保已启用定位(Location) 服务。(Services)如果您将其关闭，您的Apple Watch将无法正确校准。
启用定位(Location) 服务(Services)后，滚动到同一设置页面的底部，点击系统(System) 服务(Services)，然后启用运动校准(Motion Calibration)和距离(Distance)。
校准 Apple Watch(Calibrate Apple Watch)以获得更好的健身追踪(Better Fitness Tracking)
在获得 iPhone 权限的情况下，您应该佩戴Apple Watch，前往GPS接收良好且天空晴朗的户外开阔区域。如果您拥有Apple Watch Series 2(Apple Watch Series 2)或更新型号，则无需携带 iPhone 进行校准。但是，如果您的智能手表是Apple Watch Series 1，则必须随身携带 iPhone。
要开始校准Apple Watch，请在手表上打开“体能(Workout)训练”应用，然后开始户外步行(Outdoor Walk)或户外跑步(Outdoor Run)体能训练。您可以以正常速度步行或跑步 20 分钟，让Apple Watch完成校准。您必须进行 20 分钟的户外步行(Outdoor Walk)或户外跑步锻炼(Outdoor Run workouts)。但是，您可以将其分解为以不同速度进行的多个较短的锻炼。
只要最终总锻炼时间为 20 分钟，您的Apple Watch就会完成校准。(Apple Watch)Apple Watch会在您进行这些锻炼时自动学习您的步幅并校准加速度计。
校准完成后，您的Apple Watch应该会提供更准确的卡路里消耗数据并改善整体的健身追踪(improve fitness tracking)。
请记住(Remember)，某些数据也取决于您的健康水平。例如，职业运动员在 5 英里跑步中的最大心率可能达到 130bpm，但休闲跑步者在类似的锻炼中可能会达到 150bpm 以上。
(Reset Fitness Calibration Data)在Apple Watch上(Apple Watch)重置健身校准数据
如果您已经校准了健身数据，但仍然无法获得准确的锻炼测量结果，您可能需要尝试在Apple Watch上重置健身校准数据。
您可以通过在 iPhone 上打开Apple Watch应用并点击屏幕左下角的“我的手表”选项卡来执行此操作。(My Watch)然后您可以点击隐私(Privacy)并选择重置健身校准数据(Reset Fitness Calibration Data)。当然，您必须再次校准Apple Watch。
提高心率测量精度(Improve Heart Rate Measurement Accuracy)
即使在尝试了到目前为止描述的所有步骤后，有些人仍会遇到不准确的心率读数。尝试一些更快速的调整来解决问题。
首先，在 iPhone 上的Apple Watch应用程序中，导航到My Watch选项卡> Passcode。现在确保启用
手腕检测。(Wrist Detection)
然后，您可以返回“我的手表”(My Watch)选项卡并点击“隐私(Privacy)” 。确保启用以下选项：
接下来，您应该确保在记录锻炼时您的Apple Watch紧贴手腕。如果手表太松，可能会影响心率测量的准确性。锻炼完成后，再次松开手表。
值得注意的是，Apple Watch在(Apple Watch)省电模式下(Power Saving Mode)无法测量心率。您可以通过转到 iPhone 上的Apple Watch应用程序，导航到“我的手表”(My Watch)选项卡 > “锻炼(Workout)”并禁用“省电模式(Power Saving Mode)”来禁用它。
最后，从Apple Watch上的(Apple Watch)Workout应用程序中选择正确的锻炼方式至关重要。如果您在跑步机上不小心选择了户外步行(Outdoor Walk)或户外跑步(Outdoor Run)锻炼，您一定会得到不准确的结果。
更新 Apple Watch(Update Apple Watch)和 iPhone 软件
如果这些方法都不能帮助您获得更准确的锻炼读数，那么是时候检查您是否拥有最新版本的 iOS 或 watchOS。有时新版本的 watchOS 会链接到最新版本的 iOS，因此您必须先更新您的 iPhone，然后再更新您的智能手表(updating your smartwatch)。
例如，如果您的 iPhone 装有 iOS 14，您可能无法更新到 watchOS 8。您需要更新版本，例如 iOS 15.5 才能更新到最新版本的 watchOS。您可以在 Apple 网站上
查看最新版本的 iOS(latest version of iOS)和最新版本的 watchOS 。(latest version of watchOS)
How to Calibrate an Apple Watch for Better Fitness Tracking
Although the Apple Watch is among the most accurate wrist-worn fitness tracking devices, it sometimes can give inaccurate readings. If you’re facing this problem, we’ll show you how to calibrate your Apple Watch for better fitness tracking.
We’ll also cover other essential tweaks for more accurate workout measurements. We’ll also show you how to reset the fitness tracking calibration on your Apple Watch.
Update Health Data for the Apple Watch
Sometimes, inaccurate Apple Watch fitness tracking is due to health data. If your health details such as height, weight, age, or gender are incorrect, you’re likely to see errors in fitness tracking.
To fix this, open the Apple Watch app on your iPhone and tap the My Watch tab at the bottom of the screen. Now scroll down, go to Health > Health Details, and tap the Edit button in the top-right corner of the screen.
You can now tap each of your health details on this page and correct any inaccuracies. Once you enter your health data correctly, your Apple Watch will be able to provide you with more accurate heart rate measurements and calorie burn data.
Note that you can only pair the Apple Watch with an iPhone, so those two devices are all you’ll need for fitness tracking calibration. You cannot pair the Apple Watch with your Mac, iPad, or most other products in the Apple ecosystem.
Change iPhone Permissions for Improved Apple Watch Tracking Accuracy
Before we talk about calibration, you must check your iPhone’s permissions to help calibrate your Apple Watch. On your iPhone, open Settings, tap Privacy, and tap Location Services. On the next page, ensure that Location Services is enabled. If you’ve turned it off, your Apple Watch will not calibrate correctly.
Once Location Services is enabled, scroll to the bottom of the same settings page, tap System Services, and enable Motion Calibration & Distance.
Calibrate Apple Watch for Better Fitness Tracking
With iPhone permissions taken care of, you should wear your Apple Watch and go to an open area outdoors that has good GPS reception and clear skies. You don’t need to carry your iPhone for calibration if you have an Apple Watch Series 2 or a newer model. However, if your smartwatch is an Apple Watch Series 1, you must take your iPhone along.
To start calibrating your Apple Watch, open the Workout app on the watch, and start an Outdoor Walk or Outdoor Run workout. You can walk or run at your normal pace for 20 minutes, allowing the Apple Watch to finish calibration. You must hit 20 minutes of Outdoor Walk or Outdoor Run workouts. However, you can break it up into multiple shorter workouts performed at different speeds.
Your Apple Watch will complete calibration as long as the final total is 20 minutes of workout. The Apple Watch automatically learns your stride length and calibrates the accelerometer as you perform these workouts.
Once calibration is complete, your Apple Watch should provide more accurate calorie burn data and improve fitness tracking overall.
Remember that some data depends on your fitness levels too. For example, a professional athlete may hit a maximum heart rate of 130bpm during a 5-mile run, but casual runners may witness more than 150bpm in a similar workout.
Reset Fitness Calibration Data on Apple Watch
If you’ve already calibrated fitness data and still cannot get accurate workout measurements, you might want to try resetting fitness calibration data on your Apple Watch.
You can do this by opening the Apple Watch app on your iPhone and tapping the My Watch tab in the bottom left corner of the screen. You can then tap Privacy and select Reset Fitness Calibration Data. Of course, you’ll have to calibrate your Apple Watch again.
Improve Heart Rate Measurement Accuracy
Some people experience inaccurate heart rate readings even after trying all the steps described so far. Try a few more quick tweaks to fix the problem.
First, on the Apple Watch app on your iPhone, navigate to My Watch tab > Passcode. Now ensure that Wrist Detection is enabled.
You can then go back to the My Watch tab and tap Privacy. Ensure that the following options are enabled:
- Heart Rate
- Respiratory Rate
- Fitness Tracking
Next, you should ensure that your Apple Watch fits snugly on your wrist while recording workouts. If the watch is a bit too loose, it could affect heart rate measurements’ accuracy. When your exercises are done, loosen the watch again.
It’s worth noting that your Apple Watch cannot measure heart rate when it’s in Power Saving Mode. You can disable it by going to the Apple Watch app on your iPhone, navigating to My Watch tab > Workout, and disabling Power Saving Mode.
Finally, choosing the right workout from the Workout app on your Apple Watch is crucial. If you’re on a treadmill and accidentally select Outdoor Walk or Outdoor Run workouts, you’re bound to get inaccurate results.
Update Apple Watch and iPhone Software
If none of these methods help you get a more accurate workout reading, then it’s time to check if you have the latest version of iOS or watchOS. Sometimes new versions of watchOS are linked to the latest versions of iOS, so you’ll have to update your iPhone before updating your smartwatch.
For example, if your iPhone has iOS 14, you may be unable to update to watchOS 8. You would need a more recent version, such as iOS 15.5 to update to the latest version of watchOS. You can check the latest version of iOS and the latest version of watchOS on Apple’s website.
