您的 iPad 会自行重启吗？这是您在 Apple 的旗舰平板设备上遇到的更罕见和更严重的问题之一。有几个原因——硬件和软件相关的——可能会导致这种情况。
但是，在您开始前往最近的Apple Store修理或更换 iPad 之前，您或许可以通过以下修复工作来节省您的旅行时间。
检查闪电端口
如果 iPad 无法正常充电，它可能会自动重启。如果在连接到电源时发生这种情况，则问题可能源于充电端口、电缆或充电器。以下是您可以做的几件事：
- 检查 iPad 上的Lightning或USB-C端口是否有灰尘、棉绒或污垢。然后，用牙签或镊子撬出卡住的颗粒。
- 将(Replace)Lightning或USB-C线缆更换为来自另一台Apple设备的线缆。如果您使用第三方线缆，请确保它已通过 MFi 认证(make sure that it’s MFi-certified)。
- 尝试使用不同的壁式插座或其他充电砖。您也可以尝试将 iPad 直接连接到Mac或 PC，以确定问题是否出在充电器故障上。
更新 iPadOS
系统软件 (iPadOS) 对 iPad 的总体稳定性起着重要作用。尽管与竞争平板电脑相比，iPadOS 相对没有错误，但特定版本的 iPadOS 可能存在严重问题，导致设备无法正常工作。
因此，如果您最近没有更新 iPad，请前往“设置”(Settings ) > “通用(General )” > “软件更新”(Software Update)，然后点击“下载并安装(Download and Install)”以应用待处理的系统软件更新。
如果您的 iPad 在您可以启动更新之前没有保持开机状态，您可以尝试使用恢复模式(Recovery Mode)来更新设备（更多内容见下文）。
此外，iPadOS 的 Beta 版可能会在 iPad 上引入严重的稳定性问题。解决此问题的最佳方法是降级到 iPadOS 的稳定版本(downgrade to the stable version of iPadOS)。
更新应用
假设(Suppose)您在 iPad 上使用特定应用时一直遇到此问题。在这种情况下，您必须立即应用任何挂起的更新，因为开发人员通常会快速修复任何破坏设备的错误。
前往App Store，搜索该应用程序，如果您看到可用选项，请 点击更新。(Update )
如果您没有看到任何更新（或者尽管更新了应用程序，问题仍然存在），请尝试联系开发人员。您通常可以在应用程序的App Store页面上找到开发人员的联系方式。
此外，我们强烈建议您更新 iPad 上的所有应用程序。这可能有助于修复由在后台运行的程序(programs that run in the background)引起的主要错误。为此，请点击屏幕右上角的头像图标，然后点击全部更新(Update All)。
检查电池健康
iPad 的电池寿命为 1,000 次充电周期。因此，如果您已经使用该设备数年，您可能会看到电池严重退化。
您可以在Mac上使用第三方应用程序（例如椰子(coconutBattery)电池）来检查电池的健康状况。连接设备并选择iOS 设备(iOS Device)选项卡后，您就会发现 iPad 的充电周期数。如果您使用 PC，则可以使用iMazing等应用程序来检查电池循环计数。
如果电池已超过 1,000 次充电周期，请与Apple协商更换。或者，考虑升级到更新的 iPad(upgrading to a newer iPad)。
重置所有设置
iPadOS 有大量与网络、隐私、可访问性等相关的设置，这些设置可能会造成严重冲突并触发 iPad 自动重启。解决此问题的最佳方法是将每个设置恢复为出厂默认设置。
但别担心。在重置过程中， 您不会丢失数据（任何已保存的 Wi-Fi网络除外）。(Wi-Fi)
为此，请转到设置(Settings )>常规(General )>重置(Reset )，然后点击重置所有设置(Reset All Settings)。
恢复出厂设置 iPad
如果重置 iPad 上的所有设置无法解决问题，您的下一个选择是将 iPadOS 设备恢复出厂设置。您可以选择在重置过程之前创建数据备份，但如果您的设备不断重启，您必须回退到使用旧的 iTunes/Finder 或 iCloud 备份。但是，如果您没有备份，您将丢失所有数据。
要启动恢复出厂设置，请前往设置(Settings )>通用(General )>重置(Reset)，然后点击抹掉所有内容和设置(Erase All Content and Settings)。或者，将您的 iPad 连接到Mac或 PC，然后在Finder或 iTunes中选择“恢复 iPad”(Restore iPad)选项。您可以在重置过程后取回您的数据。
有关完整的分步说明，请查看有关将 iPad 恢复出厂设置的(factory resetting your iPad)指南。
使用恢复模式或 DFU 模式
如果问题仍然存在或您无法执行上面列出的某些修复，请尝试使用恢复模式(Recovery Mode)更新或重新安装 iPad 上的系统软件。这是一个高级恢复环境，旨在帮助解决主要问题。
进入恢复模式(entering Recovery Mode)后，首先选择更新(Update )选项以重新安装最新版本的系统软件。您不会丢失任何数据。如果这无法阻止 iPad 重新启动，请重新进入恢复模式(Recovery Mode)，但使用恢复 iPad(Restore iPad )选项。这将完全擦除所有数据，但如果您手头有以前的 iTunes 或 iCloud 备份，您可以取回所有数据。
如果恢复模式(Recovery Mode)无法修复您的 iPad，您可以通过进入并使用 DFU 模式来(entering and using DFU Mode)最后修复您的 iPad 。DFU（代表设备固件更新(Device Firmware Update)）模式(Mode)重新安装系统软件和设备固件。这可以潜在地解决由硬件级别的编程损坏引起的问题。
把它带到苹果
如果其他修复都没有帮助，您可能正在查看您无法自行修复的 iPad 硬件相关故障。因此，是时候在当地的Genius(Genius)酒吧预约并接受维修或更换了。
How to Fix an iPad that Keeps Restarting
Does your iPad keeр restarting on its own? That’s among the rarer and more severe issues you’ll encoυnter on Apple’s flagship tablet device. Several reasons—both hardware and software-related—can cauѕe that.
But before you start heading over to the nearest Apple Store to get your iPad fixed or replaced, you might be able to save yourself a trip by working your way through the fixes that follow.
Check the Lightning Ports
Your iPad may restart automatically if it can’t charge itself properly. If that happens while connected to a power source, the issue might stem from the charging port, cable, or charger. Here are a few things you can do:
- Check the Lightning or USB-C port on your iPad for dust, lint, or grime. Then, pry out the stuck particles using a toothpick or a pair of tweezers.
- Replace the Lightning or USB-C cable with one from another Apple device. If you use a third-party cable, make sure that it’s MFi-certified.
- Try a different wall socket or another charging brick. You can also try connecting your iPad to a Mac or PC directly to determine if the problem lies with a faulty charger.
Update iPadOS
The system software (iPadOS) plays a significant role in the general stability of your iPad. Despite being relatively bug-free compared to competing tablets, specific versions of iPadOS can have significant issues that prevent the device from working correctly.
So if you haven’t updated your iPad recently, go to Settings > General > Software Update and tap Download and Install to apply pending system software updates.
If your iPad doesn’t stay powered on until you can initiate an update, you can try using Recovery Mode to update the device (more on that below).
Additionally, beta versions of iPadOS can introduce severe stability issues on the iPad. The best way to fix that is to downgrade to the stable version of iPadOS.
Update Apps
Suppose you keep experiencing the issue while using a specific app on your iPad. In that case, you must immediately apply any pending updates since developers are usually quick to fix any device-breaking bugs.
Head over to the App Store, search for the app, and tap Update if you see the option available.
If you don’t see any updates (or if the issue keeps recurring despite updating the app), try contacting the developer. You can usually find the contact details for a developer on the app’s App Store page itself.
Also, we strongly recommend that you update all apps on the iPad. That might help fix major bugs caused by programs that run in the background. To do that, tap the profile portrait icon to the top-right corner of the screen and tap Update All.
Check Battery Health
The iPad’s battery has a lifespan of 1,000 charge cycles. So if you’ve used the device for several years, you might be looking at a severely degraded battery.
You can use a third-party app such as coconutBattery on the Mac to check the battery’s health. You’ll find the number of charge cycles for your iPad as soon as you connect the device and select the iOS Device tab. If you use a PC, you can use an app such as iMazing to check the battery cycle count.
If the battery has exceeded 1,000 charge cycles, talk to Apple about replacing it. Or, consider upgrading to a newer iPad.
Reset All Settings
iPadOS has loads of settings related to networking, privacy, accessibility, and so on that can create serious conflicts and trigger your iPad to restart automatically. The best way to fix that is to revert every single setting to its factory defaults.
But don’t worry. You won’t lose data (except for any saved Wi-Fi networks) during the reset procedure.
To do that, go to Settings > General > Reset and tap Reset All Settings.
Factory Reset iPad
If resetting all settings on your iPad didn’t do anything to fix the issue, your next option is to factory reset your iPadOS device. You can choose to create a backup of your data before the reset procedure, but if your device keeps restarting, you must fall back to using an old iTunes/Finder or iCloud backup. However, if you don’t have a backup, you’ll lose all of your data.
To initiate a factory reset, go to Settings > General > Reset and tap Erase All Content and Settings. Or, connect your iPad to a Mac or PC and select the Restore iPad option in Finder or iTunes. You can get your data back after the reset procedure.
For complete step-by-step instructions, check out this guide about factory resetting your iPad.
Use Recovery Mode or DFU Mode
If the issue persists or you can’t perform some of the fixes listed above, try using Recovery Mode to update or reinstall the system software on your iPad. It’s an advanced recovery environment designed to help troubleshoot major issues.
After entering Recovery Mode, start by selecting the Update option to re-install the latest version of the system software. You won’t lose any data. If that fails to stop the iPad from restarting, re-enter Recovery Mode, but use the Restore iPad option. That will completely wipe all data, but you can get back everything if you have a previous iTunes or iCloud backup at hand.
If Recovery Mode fails to do anything to fix your iPad, you can take the last shot at fixing your iPad by entering and using DFU Mode. DFU (which stands for Device Firmware Update) Mode reinstalls the system software and the device firmware. That can potentially resolve issues caused by corruption in programming at the hardware level.
Take It to Apple
If none of the other fixes helped, you’re likely looking at a hardware-related fault with your iPad that you can’t fix by yourself. So, it’s time to book an appointment at the local Genius bar and take it in for repairs or a replacement.
