如果您的 iPhone 不断重新启动，然后在再次开机时
显示Apple徽标，您可能会摸不着头脑，想知道可能发生了什么。(Apple)
发生这种情况的原因有多种，我们找到了最可能的原因和解决方案，可以让您的 iPhone 恢复正常。如果您在使用 iPad 时遇到此问题，这些相同的提示通常也适用。
iPhone XS Max、X、XS 和 XR
的注意事项
虽然任何 iOS 设备都可能因各种原因发生此问题，但根据互联网论坛帖子和社交媒体的讨论，iPhone X 系列似乎特别容易出现此问题。我们不知道这些手机是否真的比任何其他型号都更频繁地重新启动并显示苹果(Apple)标志，但似乎确实有更多的人专门拥有这些手机。
Settings > General > Reset > Reset All Settings重置 iPhone 设置。
您的 iPhone 的设置将重置为默认值。这包括Wi-Fi(Wi-Fi)、蓝牙(Bluetooth)和主屏幕布局等设置。您对 iPhone 设置所做的任何自定义设置都将丢失。例如，如果您更改了壁纸或铃声，这些自定义设置将会丢失。您的 iPhone 的数据和媒体不会受到重置的影响。您的照片、音乐和其他数据不会被删除。
1. 给手机充电
如果您的 iPhone 在电池电量不足时关闭，请尝试充电，看看是否能解决问题。如果电池完全耗尽，充电过程可能需要几分钟才能开始。
如果您的电池寿命很短并且想要防止手机完全关闭，
您可能需要打开低电量模式。(Low Power Mode)
2.检查电池健康状况
您的 iPhone 电池可能会耗尽，导致突然重启或关机。如果当您的手机处于紧张状态时（例如玩游戏时）发生这种情况，则表明电池可能是罪魁祸首。您可以按照以下步骤检查 iPhone 的电池健康状况：
- 打开iPhone 上的
“设置”应用。(Settings)
- 点击电池。
- 选择电池健康和充电。
- 向下滚动(Scroll)并查找“电池健康状况”(Battery Health)部分。
“电池健康”部分将向您显示电池的最大容量及其当前充电水平。健康的电池应具有至少 80% 的最大容量。如果您的电池的最大容量低于 80%，则可能需要更换电池。
3.重新启动(Reboot)以解决随机软件故障(Solve Random Software Glitches)
如果您的 iPhone 意外关闭而不是由于电池电量不足，则可能是软件问题。尝试按住电源按钮直到出现“滑动关闭电源”滑块来强制重新启动 iPhone。然后，滑动以关闭设备电源并等待几秒钟，然后再次按电源按钮将其重新打开。
如果您的 iPhone 没有物理主页(Home)按钮，则必须按住音量调高按钮和侧边按钮(Side Button)才能看到滑块。iPhone 8 和 8s 是最后一款配备物理Home键的机型。因此，如果您拥有一台或旧设备（例如 iPhone 6s 或 iPhone 7），则必须使用此方法。
4.将您的固件(Firmware)更新(Update)到最新(Latest)版本
iOS 的每个版本（或任何相关软件）都必然存在一些错误。您的特定手机可能由于 iOS 中的错误而出现故障。因此，请转到Settings > General > Software Update，然后检查是否有任何可用的 iOS 更新
消除第三方应用程序(Third-Party Apps)作为原因
如果您怀疑第三方应用程序可能导致您的 iPhone 重新启动，您可以尝试采取一些措施来解决该问题。
- 确保(Make)您的所有应用程序都是最新的。有时，应用程序更新可以解决可能导致 iPhone 重新启动的问题。
- 如果某个应用程序导致您的 iPhone 重新启动，请尝试将其关闭。双击(Double-tap)主页按钮以调出应用程序切换器或从屏幕底部向上滑动，然后在应用程序上向上滑动以将其关闭。
- 尝试重新启动您的 iPhone，看看是否可以解决问题。
- 如果上述方法均不起作用，您可能需要卸载该应用程序。为此，请按住应用程序图标直至其开始晃动。点击应用程序上的“x”即可将其卸载。
- 如果您已尝试上述步骤但问题仍然存在，您可能需要联系应用程序的开发人员以获取进一步帮助。您通常可以在App Store(App Store)或开发者的网站上
找到应用程序开发者的联系信息。
卸载（而不是卸载）应用程序将从您的 iPhone 中删除该应用程序的所有数据。卸载应用程序之前，请(Make)务必备份所有重要数据！
5. 硬件问题
如果您尝试重新启动 iPhone 并更新软件，但问题仍然存在，则可能是硬件问题。尝试将 iPhone 连接到电脑，看看是否可以识别。如果无法识别，则可能需要专业维修。
如果您的 iPhone 接触过液体，这可能是问题的根源。虽然您可以尝试擦干手机以希望问题得到解决，但如果液体已渗透到手机足以导致奇怪的行为，则需要由技术人员进行检查。
6.你的iPhone太热了！
如果您的 iPhone 由于过热而关闭，请尝试让它冷却后再重新打开。避免(Avoid)使用资源密集型应用程序或在炎热的环境中为 iPhone 充电，因为这可能会导致 iPhone 过热。
7. 充电端口损坏
如果您的 iPhone 在插入充电时关闭，可能是由于充电端口损坏造成的。尝试使用不同的充电线和电源插座，看看问题是否仍然存在。如果出现这种情况，可能需要请专业人员维修充电端口。
8.使用恢复模式(Phone Using Recovery Mode)恢复手机
iPhone 和 iPad 等Apple(Apple)设备有一种特殊的恢复模式，称为DFU 模式(DFU Mode)。在此模式下，您甚至可以修复固件损坏的 iPhone，因为您可以使用 iTunes ( Windows(Windows) ) 或 macOS等外部应用程序来恢复手机的固件。
9. 检查是否存在恶意软件

iPhone Keeps Turning On and Off? 10 Ways to Fix
If your iPhone keeps restarting and then diѕplaying the Aрple lоgo as it powers up again by itself, you’re probably scratching your head, wondering what coυld possibly be going on.
There are various reasons why this could be happening, and we’ve found the most likely causes and solutions to get your iPhone back to normal. If you’re experiencing this issue with an iPad, these same tips should apply in general.
A Note for the iPhone XS Max, X, XS, and XR
While this issue can happen with any iOS device for various reasons, based on internet forum posts and social media chatter, it seems that the iPhone X family might be particularly prone to this issue. We don’t know if these phone’s really keep restarting and showing the Apple logo more than any other model, but it does seem that more people are complaining about it who own these phones specifically.
Either way, it seems the most reliable fix is to reset your iPhone settings by going to Settings > General > Reset > Reset All Settings.
Your iPhone’s settings will be reset to their default values. This includes settings for things like Wi-Fi, Bluetooth, and your home screen layout. Any customizations you’ve made to your iPhone’s settings will be lost. For example, if you’ve changed your wallpaper or ringtone, those customizations will be lost. Your iPhone’s data and media won’t be affected by the reset. Your photos, music, and other data won’t be deleted.
1. Charge Your Phone
If your iPhone is turning off when the battery is low, try charging it and see if that resolves the issue. If the battery is completely drained, it may take a few minutes for the charging process to begin.
You may want to turn on Low Power Mode if you have little battery life and want to prevent your phone from turning off completely.
2. Check Your Battery Health
Your iPhone’s battery may be worn out, leading to sudden restarts or shutdowns. If this happens when your phone is under strain, such as when playing games, it points to the battery being a likely culprit. You can check the battery health of your iPhone by following these steps:
- Open the Settings app on your iPhone.
- Tap on Battery.
- Select Battery Health & Charging.
- Scroll down and look for the Battery Health section.
The “Battery Health” section will show you the maximum capacity of your battery, as well as its current charge level. A healthy battery should have a maximum capacity of at least 80%. If your battery has a maximum capacity of less than 80%, it may be time to replace it.
3. Reboot to Solve Random Software Glitches
If your iPhone is turning off unexpectedly and not due to a low battery, it could be a software issue. Try to force restart your iPhone by holding the power button until the “Slide to Power Off” slider appears. Then, slide to power off your device and wait a few seconds before pressing the power button again to turn it back on.
If you have an iPhone without a physical Home button, you’ll have to hold down the Volume Up button and the Side Button to see the slider. The iPhone 8 and 8s were the last models to feature a physical Home button. So if you own one or something older (e.g. iPhone 6s or iPhone 7) you’ll have to use this method.
4. Update, Your Firmware to the Latest Version
Every version of iOS (or any software for that matter) is bound to have some bugs in it. It may be that your particular phone is acting up because of bugs in iOS. So go to Settings > General > Software Update and check if any iOS updates are available
Eliminate Third-Party Apps as the Cause
If you suspect that a third-party app may be causing your iPhone to restart, there are a few things you can try to resolve the issue.
- Make sure that all of your apps are up to date. Sometimes, updates to apps can fix issues that may be causing your iPhone to restart.
- If an app is causing your iPhone to restart, try closing it. Double-tap the home button to bring up the app switcher or swipe up from the bottom of the screen, then swipe up on the app to close it.
- Try restarting your iPhone to see if that resolves the issue.
- If none of the above work, you may need to uninstall the app. To do this, press and hold on the app icon until it starts shaking. Tap the “x” on the app to uninstall it.
- If you’ve tried the above steps and the issue persists, you may want to contact the developer of the app for further assistance. You can usually find contact information for app developers in the App Store or on the developer’s website.
Uninstalling (rather than offloading) an app will delete all of the app’s data from your iPhone. Make sure to back up any important data before uninstalling an app!
5. Hardware Problems
If you’ve tried restarting your iPhone and updating the software, but the issue persists, it could be a hardware issue. Try connecting your iPhone to a computer and see if it is recognized. If it is not recognized, it could require professional repair.
If your iPhone has been exposed to liquids, that may be at the root of the problem. While you can try and dry the phone in hopes that the problem resolves, if the liquid has penetrated the phone enough to cause weird behavior, it needs to be inspected by a technician.
6. Your iPhone Is Too Hot!
If your iPhone is turning off due to overheating, try letting it cool down before turning it back on. Avoid using resource-intensive apps or charging your iPhone in hot environments, as this can cause it to overheat.
7. A Busted Charging Port
If your iPhone turns off when you plug it in to charge, it could be due to a damaged charging port. Try using a different charging cable and a power outlet to see if the issue persists. If it does, it may be necessary to have the charging port repaired by a professional.
8. Restore Your Phone Using Recovery Mode
Apple devices like iPhones and iPads have a special recovery mode called DFU Mode. In this mode, you can even fix iPhones with corrupted firmware since you use an external application such as iTunes (Windows) or macOS to restore the phone’s firmware.
9. Check for Malware
While it’s much rarer on an iOS or iPadOS device than on devices running Android, there’s a small chance your problems are caused by malware. In general, this only really happens with jailbroken iPhones running unsigned apps. So if your phone has been jailbroken, consider undoing your jailbreak to see if that helps.
Before you assume it’s a virus, first learn the signs of a virus infection or whether your iPhone has been hacked.
10. Contact Apple Support
If you’re having trouble with your iPhone and are unable to resolve the issue on your own, you may want to contact Apple for further assistance. Here are a few options for getting in touch with Apple:
- Many Apple stores have a “Genius Bar” where you can get help with your iPhone. To make an appointment at the Genius Bar, visit the Apple website to reserve an appointment.
- You can call Apple’s customer service hotline to speak with a representative. To find the phone number for your region, visit the Apple website and select your country or region.
- You can also contact Apple online by visiting the Apple website and using the “Contact Us” page. Here, you’ll be able to submit a question or request assistance through an online form.
To get help from Apple, you’ll need to provide your iPhone’s serial number. You can find the serial number on the back of your iPhone or by going to Settings > General > About on your device.
It’s also a good idea to have any relevant information about your iPhone’s issue on hand when you contact Apple, as this can help them troubleshoot the problem more effectively.
