如果您使用 iPhone 或 iPad，您很可能在某个时候遇到过设备死机的情况。这通常是由于应用程序占用的内存超出预期。您的 iPhone 或 iPad 越旧(older your iPhone or iPad)，在使用现代应用程序时就越有可能死机。
有几种方法可以解冻无响应的设备。如果这些都失败了，硬重置将纠正 iPad 或 iPhone 中的大多数问题。

有几种方法可以纠正 iPad 中的冻结问题。解决方案是否有效取决于首先导致它冻结的原因。
如果您的 iPad 电量不足，它通常会降低性能。如果您使用的是内存密集型应用程序，这些应用程序可能会导致 iPad 死机。如果您的 iPad 死机，请先尝试将其连接到电源。
如果将 iPad 连接到电源不起作用，请关闭所有可以关闭的应用程序。太多的应用程序（或一些密集型应用程序）可能会降低设备速度。如果在 iPad 上使用 iOS 12 或更高版本，您可以通过双击主(Home )屏幕按钮并从屏幕底部向上滑动来关闭应用程序。
密切关注导致 iPad 死机的任何特定应用程序。如果有一个应用程序比其他应用程序更频繁地冻结，请考虑卸载并重新安装它。应用程序数据可能已损坏，或者原始安装可能存在导致这些问题的问题。重新安装通常可以解决这些问题。

如果上述解决方案均未解决问题，则需要重置 iPad。根据您拥有的 iPad 型号，有两种主要方法可以做到这一点。“软”重置和“强制重启”之间也有区别。
要执行软重置，请按住电源按钮(power button)，直到滑块出现在屏幕顶部。向右滑动滑块以关闭 iPad。完全关闭后，再次按住电源按钮，直到出现Apple标志。
当然，软重置仅在设备响应时才有效。如果它完全冻结并且不会响应任何输入，则可能需要强制重启。根据您的 iPad 是否有主页(Home)按钮，有不同的方法可以执行此功能。
- 如果您的 iPad 有主(Home)屏幕按钮，请同时按住电源按钮(Power Button )和主屏幕按钮(Home Button)。按住它们直到设备重新启动并出现Apple标志。
- 如果您的 iPad 没有主(Home)屏幕按钮，请按住音量按钮或顶部按钮以重新启动。
如果您的设备没有响应，请快速按下并松开音量调高(Volume Up)按钮，然后同样按下音量调低(Volume Down )按钮，然后按住电源(Power )按钮强制重启设备。

iPhone 可能会因为许多与 iPad 相同的原因而死机。如果您打开的应用程序过多、电量不足或应用程序出现故障(malfunctioning app)，您的 iPhone 可能会变慢并无响应。
与 iPad 一样，您应该尝试的第一个选项是将手机连接到电源。这通常会清除因电池电量不足而引起的任何问题。如果这不起作用，请尝试关闭尽可能多的应用程序。在现代 iPhone 上，您可以通过从屏幕底部向上滑动并按住它直到应用程序出现来执行此操作。
如果这不能解冻您的手机，则下一步是重新启动或重置。

与 iPad 一样，iPhone 也有不同类型的重置。“软重置”本质上是一个电源循环，而当 iPhone 完全锁定并且您无法使用它时使用强制重启。
要执行软重置，请同时按下提高音量(Volume Up)或降低音量(Volume Down )按钮和Sleep/Wake按钮，直到出现滑块。当它出现时，向右滑动以关闭设备。根据您打开的应用程序数量，您的手机可能需要几秒钟才能完全关闭。完成后，按住电源按钮，直到出现Apple标志。
要执行强制重启，请按下并松开提高音量(Volume Up )按钮，然后对降低音量按钮执行相同操作(Volume Down)。最后，按住Sleep/Wake 按钮，直到出现Apple标志。
如何备份您的数据(How To Backup Your Data)
如果您的 iPhone 或 iPad 经常死机并且您找不到原因，则可能存在更深层次的问题。在这种情况下，您的数据可能存在风险，因此最好备份您的设备以防止丢失任何重要信息。
有多种方法可以备份您的信息，这些方法适用于 iPad 和 iPhone。第一个（也是最简单的）选项是通过 iCloud 进行备份。为此，请转到Settings > [Your Name] > iCloud > iCloud Backup. 您可以选择具体备份到 iCloud 的内容。但要记住的最重要的事情是向下滚动并确保将iCloud 备份(iCloud Backup)设置为开启。(On.)
下一个选项是使用您的计算机备份您的设备。如果使用Mac，请在Finder 边栏中查找(Finder sidebar)您的设备。从这里，转到Finder窗口的顶部，然后单击General。选择将所有数据备份到Mac的选项，然后单击立即备份。(Back Up Now.)给流程时间来完成，但您的数据将被备份。
在Windows上，您需要使用 iTunes 来执行备份。通过USB连接您的设备，然后打开 iTunes(open iTunes)。单击设备的 iTunes 窗口中的图标，然后单击摘要(Summary)。在“摘要(Summary)”窗口中，单击“立即备份”。(Back Up Now.)
How to Reset or Unfreeze an iPad or iPhone
If you use an iPhone or iPad, you have most likely exрerienced the device freezing at some point or another. Thіs is usually caused by an аpp taking up more mеmory than еxpeсted. The older your iPhone or iPad is, the more likely it is to freeze when working with modern apps.
There are several ways to unfreeze a non-responsive device. If those fail, a hard reset will correct the majority of issues in an iPad or iPhone.
How To Unfreeze An iPad
There are several ways to correct freezing issues in an iPad. Whether a solution will work or not depends on what caused it to freeze in the first place.
If your iPad is low on power, it will often throttle performance. If you’re using memory-intensive apps, these can cause the iPad to freeze. If your iPad freezes, first try connecting it to power.
If connecting the iPad to power doesn’t work, close any apps you can. Too many apps (or a few intensive apps) can slow down the device. If using iOS 12 or later on your iPad, you can close apps by double-clicking the Home button and swiping up from the bottom of the screen.
Keep an eye on any particular apps that cause your iPad to freeze. If there’s one app that freezes more often than others, consider uninstalling and reinstalling it. The app data may be corrupt or there may be a problem with the original installation that caused these issues. Reinstalling often resolves these issues.
How To Reset An iPad
If none of the solutions above solved the problem, you will need to reset the iPad. There are two main ways to do this depending on the model of iPad you have. There’s also a difference between a “soft” reset and a “force restart.”
To perform a soft reset, press and hold the power button until the slider appears at the top of your screen. Swipe the slider to the right to power down the iPad. Once it shuts down entirely, press and hold the power button again until the Apple logo appears.
Of course, a soft reset only works if the device is responsive. If it’s completely frozen and won’t respond to any input, a force restart may be required. There are different ways to perform this function based on whether your iPad has a Home button or not.
- If your iPad has a Home button, press and hold down the Power Button and the Home Button at the same time. Hold them down until the device reboots and the Apple logo appears.
- If your iPad doesn’t have a Home button, press and hold either the volume button or the top button to restart.
If your device doesn’t respond, quickly press and release the Volume Up button, then the same for the Volume Down button, and then press and hold the Power button to force restart the device.
How To Unfreeze An iPhone
An iPhone can freeze for many of the same reasons as an iPad. If you have too many apps open, it’s low on power, or there’s a malfunctioning app, your iPhone may slow down and become unresponsive.
Like the iPad, the first option you should try is connecting your phone to power. This will often clear up any issues caused by low battery levels. If that doesn’t work, try to close as many apps as you can. On modern iPhones, you do this by swiping up from the bottom of the screen and holding it until the apps appear.
If this does not unfreeze your phone, a restart or reset is the next step.
How To Reset An iPhone
Like the iPad, there are different types of resets for the iPhone. A “soft reset” is essentially a power cycle, while a force restart is used when the iPhone is completely locked down and you can’t use it.
To perform a soft reset, press the Volume Up or Volume Down button and Sleep/Wake button at the same time until the slider appears. When it does, swipe right to turn the device off. Depending on how many apps you had open, it may take several seconds for your phone to shut down entirely. Once it does, press and hold the power button until the Apple logo appears.
To perform a force restart, press and release the Volume Up button, then do the same for the Volume Down button. Finally, press and hold the Sleep/Wake button until the Apple logo appears.
How To Backup Your Data
If your iPhone or iPad is freezing often and you can’t find the cause, there may be a problem on a deeper level. In this case, your data might be at risk, so it’s a good idea to back up your device to prevent the loss of any important information.
There are several ways to backup your information, and these work for both iPad and iPhones. The first (and easiest) option is to backup via iCloud. To do this, go to Settings > [Your Name] > iCloud > iCloud Backup. You can choose what specifically is backed up to iCloud. But the most important thing to remember is to scroll down and ensure that iCloud Backup is set to On.
The next option is to backup your device using your computer. If using a Mac, look for your device in the Finder sidebar. From here, go to the top of the Finder window and click General. Select the option to back up all of your data to your Mac, and then click Back Up Now. Give the process time to complete, but your data will be backed up.
On Windows, you will need to use iTunes to perform a backup. Connect your device via USB and then open iTunes. Click the icon in the iTunes window for your device, and then click Summary. From within the Summary window, click Back Up Now.
