iOS 是稳定的，但即使是稳定的操作系统也可能会遇到随机错误、故障和其他与软件相关的障碍。与任何其他台式机或移动设备一样，重新启动 iPhone 通常是解决问题的最佳方法。
软重置可清除 iPhone 的系统缓存，并为执行其他故障排除提供了一个极好的起点。继续阅读以了解重启任何 iOS 设备的多种方法。
为什么你应该重启你的 iPhone
重新启动 iPhone 可以解决许多阻止设备正常运行的问题。例如，如果出现以下情况，您可以试一试：
- iOS 感觉缓慢而迟钝(iOS feels slow and sluggish)。
- 应用程序(Apps)未按预期响应或工作。
- 应用程序下载或更新时间过长、冻结或失败(App downloads or updates take too long, freeze, or fail)。
- 不能更新系统软件(You can’t update the system software)。
- 您无法连接到互联网(You can’t connect to the internet)。
- 您的Apple ID或 iCloud帐户(Account)不同步。
不要无故重启你的 iPhone。iOS 通常在保持一切以最佳状态运行方面(keeping everything running in top shape)做得非常好，你可以连续几个月不用重启设备。
通过 iOS设置应用重启 iPhone(Settings App)
iPhone 上的“设置”(Settings)应用程序具有专用的关机(Shut Down)选项，您可以使用它来关闭和重新启动设备。它适用于所有 iOS 设备，包括 iPad。

无法重新启动您的 iPhone？
如果您无法按照上述说明重新启动 iPhone，则系统软件可能已完全冻结。如果是这样，请将您的 iPhone(put your iPhone through a force-restart or hard-reset)改为强制重启或硬重置。如果 iOS 继续死机，请使用Mac或 PC上的Finder或 iTunes在恢复模式下将设备恢复出厂设置(factory reset the device in Recovery Mode)。

Restart iPhone Using AssistiveTouch
AssistiveTouch is an accessibility-related feature that can help you restart your iPhone without you having to press any buttons whatsoever. Go through the steps below to activate and use AssistiveTouch to reboot an iOS device.
