您的Apple Pencil会随机断开与 iPad 的连接吗？本故障排除指南将解释为什么会发生这种情况，以及您可以采取哪些措施来解决两台设备之间的连接问题。
Apple Pencil不断断开连接的原因有多种。例如，这可能是 iPad 的蓝牙(Bluetooth)无线电出现故障、其他蓝牙(Bluetooth)设备的无线干扰或Apple Pencil笔尖出现故障。
通过以下修复，您应该能够让您的Apple Pencil再次与您的 iPad mini、iPad Air或 iPad Pro无缝协作。
1.在 iPad 上
启用(Enable)和禁用蓝牙(Disable Bluetooth)
Apple Pencil依靠蓝牙(Bluetooth)进行连接，因此最好先短暂禁用然后再启用 iPad 上的蓝牙功能。(Bluetooth)这解决了阻止设备保持持续蓝牙(Bluetooth)连接的常见技术故障。
- 从 iPad 的主屏幕(Home Screen)或应用程序库(App Library)打开“设置”(Settings)应用程序。
- 在边栏上选择蓝牙(Bluetooth)类别。
- 关闭蓝牙(Bluetooth)旁边的开关。
- 最多等待 10 秒钟。
- 再次重新启用蓝牙(Bluetooth)开关。
2. 重启你的 iPad
(Reboot)如果您的Apple Pencil在(Apple Pencil)蓝牙(Bluetooth)关闭和打开后仍然断开连接，请重新启动iPad 上的系统软件。听起来很简单，但重启几乎总能解决大多数与蓝牙(Bluetooth)相关的问题。
要重启任何 iPad 型号(restart any iPad model)：
- 打开“设置”(Settings)应用程序，然后点按“General > Shutdown” 。
- (Drag)沿着滑动到关机滑块(Power)拖动(Off)电源图标(Power)。
- 等待 30 秒并按住Top/Power按钮，直到您看到Apple标志。
没有运气？尝试强制重启。如果您的 iPad 有主(Home)屏幕按钮，只需按住主(Home)屏幕按钮和顶部(Top)按钮，直到您看到Apple标志。如果您使用没有主(Home)屏幕按钮的 iPad：
- 快速(Quickly)按下并释放音量调高按钮。
- 快速(Quickly)按下并释放降低音量按钮(Down)。
- 按住顶部(Top)按钮，直到看到Apple标志。
3. 为 Apple Pencil 充电
如果您长时间使用Apple Pencil，它可能没有足够的电池续航时间来维持稳定的连接。
前往Settings > Apple Pencil以检查 Apple Pencil 的电池寿命或使用 iPad 的“电池”小部件(use the iPad’s Battery widget)。如果电量低，请至少充电 15 分钟，然后再使用。
- 为第一代 Apple Pencil(Generation Apple Pencil)充电：取下Apple Pencil笔帽并将其插入 iPad 的闪电(Lightning)端口。
- 为第二代 Apple Pencil(Generation Apple Pencil)充电：将Apple Pencil连接到 iPad 右侧的磁性连接器（纵向）。
4.禁用其他蓝牙设备
来自其他蓝牙(Bluetooth)设备的信号干扰可能会阻止 Apple 的手写笔与您的 iPad 通信。例如，如果您在 iPad 上使用无线耳机，请将其关闭并检查是否有影响。
除了蓝牙(Bluetooth)设备之外，周围环境中还可能存在其他无线干扰源，例如未屏蔽的电源线和厨房设备。如果您怀疑有类似情况，请将您的 iPad 移到其他位置。
5. 更新你的 iPad
(Apple Pencil)iPad 系统软件问题也可能导致Apple Pencil断开连接。例如，主要 iPadOS 升级的早期版本（例如 iPadOS 16.0）包含许多错误和故障。修复它们的唯一方法是继续安装较新的点更新。
要更新 iPad：
1. 打开“设置”(Settings)应用程序并点击边栏上的
“通用”。(General)
2.点击软件更新(Tap Software Update)并等待您的 iPad 扫描系统软件更新。
3. 点击下载并安装。
6.取消配对并重新连接 Apple Pencil(Reconnect Apple Pencil)
间歇性断开Apple Pencil(Apple Pencil)的另一个原因是损坏的蓝牙(Bluetooth)设备缓存。将Apple Pencil(Apple Pencil)断开(Disconnecting)并重新连接到您的 iPad 应该可以很快摆脱它。
1. 打开设置(Settings)应用程序并点击蓝牙(Bluetooth)。
2. 点击Apple Pencil(Apple Pencil)旁边的更多信息图标。
3. 点击忘记此设备。
4. 点击忘记设备进行确认。
5. 重新连接您的Apple Pencil。如果您使用第一代Apple Pencil，只需将其插入 iPad 的闪电(Lightning)接口即可。如果您使用第二代Apple Pencil，请将它夹在 iPad 的右侧。
7. 更换 Apple Pencil 笔尖
除非您使用的是相当新的Apple Pencil，否则手写笔的笔尖总是有可能因经常使用而磨损。这会降低响应速度，并使您的Apple Pencil(Apple Pencil)看起来好像正在与 iPad 断开连接。如果笔尖形状不规则，则必须更换它。
您可以从 Apple或Amazon购买一包新提示(buy a pack of new tips from Apple)。但是，如果您使用的是第一代Apple Pencil，包装内应该有一个备用笔尖。
要更换 Apple Pencil 笔尖：
- 挤压Apple Pencil笔尖并逆时针旋转以将其拧下。
- 将新尖端放在金属换能器上。
- 顺时针转动尖端以将其拧紧。
8. 更换 iPad屏幕保护膜(Screen Protector)
如果您的 iPad 有屏幕保护膜，它可能会被划伤或磨损。这会延迟甚至停止您的Apple Pencil输入，因此请考虑更换它。
一些适用于 iPad 的钢化玻璃和薄膜也不适合Apple Pencil，因此在投资购买新的屏幕保护膜之前先进行研究。
9. 重置 iPad 设置
如果上述解决方案均无济于事，我们建议您将 iPad 上的所有设置重置为出厂默认设置。在此过程中，您不会丢失数据或媒体（保存的 Wi-Fi 网络和密码除外），因此如果您想继续：
- 打开“设置”(Settings)应用程序并轻点“General > Transfer”或“重置(Reset)iPad ” > Reset” 。
- 点击重置所有设置。
- 输入您的设备密码，然后点击重置(Reset)以确认。
执行所有设置重置后，将Apple Pencil与 iPad 配对并进行测试。如果设置配置冲突或损坏导致断开连接，从现在开始您应该不会遇到任何麻烦。
注意：由于所有设置重置会将您的隐私、辅助功能和网络设置恢复为默认设置，因此请不要忘记按照您希望的方式重新配置您的 iPad。
你的Apple Pencil 又能正常工作了(Apple Pencil Works Normally Again)
Apple Pencil断开连接很容易进行故障排除，通过切换蓝牙(Bluetooth)、重启 iPad 或取消配对并重新连接等快速修复，即使不是所有时间，也能在大多数情况下正常工作。但是，如果问题仍然存在并且其他修复方法均无济于事，则您可能遇到了硬件问题。
联系 Apple 支持，如果需要，可在离您最近的(Contact Apple Support)Apple Store进行预约。如果您的Apple Pencil(Apple Pencil)仍在保修期内（自购买之日起一年），
您可能有权获得更换。
Apple Pencil Keeps Disconnecting? 9 Ways to Fix
Does your Apple Pencil randomly disconnect from your iPad? This troubleshooting guide will explain why that happens and what you can do to fіx сonnectivity issues between the two devices.
There are several reasons why your Apple Pencil keeps disconnecting. For example, it could be a glitch with your iPad’s Bluetooth radio, wireless interference from other Bluetooth devices, or a faulty Apple Pencil nib.
Work your way through the following fixes, and you should be able to get your Apple Pencil working seamlessly with your iPad mini, iPad Air, or iPad Pro again.
1. Enable & Disable Bluetooth on iPad
The Apple Pencil relies on Bluetooth for connectivity, so it’s best to begin by briefly disabling and then enabling the Bluetooth functionality on your iPad. That resolves common technical glitches preventing devices from maintaining a constant Bluetooth connection.
- Open the Settings app from your iPad’s Home Screen or App Library.
- Select the Bluetooth category on the sidebar.
- Turn off the switch next to Bluetooth.
- Wait for up to 10 seconds.
- Re-enable the Bluetooth switch again.
2. Restart Your iPad
Reboot the system software on your iPad if your Apple Pencil continues to disconnect despite toggling Bluetooth off and on. It sounds simple, but a restart almost always fixes most Bluetooth-related problems.
To restart any iPad model:
- Open the Settings app and tap General > Shutdown.
- Drag the Power icon along the Slide to Power Off slider.
- Wait 30 seconds and hold the Top/Power button until you see the Apple logo.
No luck? Try a force-restart instead. If your iPad has a Home button, just hold the Home and Top buttons until you see the Apple logo. If you use an iPad without a Home button:
- Quickly press and release the Volume Up button.
- Quickly press and release the Volume Down button.
- Hold the Top button until you see the Apple logo.
3. Charge Apple Pencil
If you’ve been using your Apple Pencil for an extended period, it might not have enough battery life to maintain a stable connection.
Go to Settings > Apple Pencil to check your Apple Pencil’s battery life or use the iPad’s Battery widget. If it’s low, charge it for at least 15 minutes before using it again.
- Charge 1st Generation Apple Pencil: Remove the Apple Pencil cap and insert it into the Lightning port of your iPad.
- Charge 2nd Generation Apple Pencil: Attach the Apple Pencil to the magnetic connector on the right side of your iPad (in portrait orientation).
4. Disable Other Bluetooth Devices
Signal interference from other Bluetooth devices can stop Apple’s stylus from communicating with your iPad. For example, if you use a wireless headset with your iPad, turn it off and check if that makes a difference.
Bluetooth devices aside, there could also be other sources of wireless interference in your surrounding environment—e.g., unshielded power cables and kitchen equipment. Move your iPad to a different location if you suspect something like that.
5. Update Your iPad
Apple Pencil disconnects could also occur due to iPad system software problems. For example, early versions of major iPadOS upgrades—e.g., iPadOS 16.0—contain numerous bugs and glitches. The only way to fix them is to continue installing newer point updates.
To update an iPad:
1. Open the Settings app and tap General on the sidebar.
2. Tap Software Update and wait until your iPad scans for system software updates.
3. Tap Download and Install.
6. Unpair and Reconnect Apple Pencil
Another reason for an intermittently disconnecting Apple Pencil is a corrupt Bluetooth device cache. Disconnecting and reconnecting the Apple Pencil to your iPad should quickly get rid of it.
1. Open the Settings app and tap Bluetooth.
2. Tap the More Info icon next to your Apple Pencil.
3. Tap Forget This Device.
4. Tap Forget Device to confirm.
5. Reconnect your Apple Pencil. If you use a 1st gen Apple Pencil, simply insert it into the iPad’s Lightning connector. If you use a 2nd-gen Apple Pencil, clamp it to the right side of your iPad.
7. Replace Apple Pencil Nib
Unless you’re using a fairly new Apple Pencil, there is always a chance that the tip of the stylus has worn out with regular use. That decreases responsiveness and makes it appear as if your Apple Pencil is disconnecting from your iPad. If the nib has an irregular shape, you must replace it.
You can buy a pack of new tips from Apple or Amazon. However, if you use a 1st-gen Apple Pencil, there should be a spare tip inside the packaging.
To replace an Apple Pencil tip:
- Squeeze the Apple Pencil tip and turn it counterclockwise to unscrew it.
- Place the new tip on the metal transducer.
- Turn the tip clockwise to tighten it.
8. Replace the iPad Screen Protector
If your iPad has a screen protector, it could be scratched or scuffed up. That delays—or even stops—input from your Apple Pencil, so consider replacing it.
Some tempered glasses and films for the iPad are also not suited for the Apple Pencil, so do your research before investing in a new screen protector.
9. Reset iPad Settings
If none of the solutions above help, we recommend resetting all settings on your iPad to factory defaults. You will not lose data or media—except for saved Wi-Fi networks and passwords—during the process, so if you want to go ahead:
- Open the Settings app and tap General > Transfer or Reset iPad > Reset.
- Tap Reset All Settings.
- Enter your device passcode, and tap Reset to confirm.
After performing an all-settings reset, pair the Apple Pencil with your iPad and test things out. If a conflicting or broken settings configuration caused the disconnects, you shouldn’t have any trouble from here on out.
Note: Since an all-settings reset reverts your privacy, accessibility, and network settings to their defaults, don’t forget to reconfigure your iPad the way you want it to work.
Your Apple Pencil Works Normally Again
Apple Pencil disconnects are easy to troubleshoot, with quick fixes like toggling Bluetooth, restarting your iPad, or unpairing and reconnecting working most if not all the time. However, if the problem persists and none of the other fixes help, you might be dealing with a hardware problem.
Contact Apple Support, and if needed, book an appointment at your closest Apple Store. You might be entitled to a replacement if your Apple Pencil is still within the warranty period (one year from the date of purchase).
