手机配置为自动安装软件和应用程序更新——尽管某些iOS 更新(iOS updates)必须手动安装。让您的 iPhone 和应用程序自行更新到最新版本很方便。但是，在某些情况下，手动启动这些更新更有益。
我们将引导您了解手动安装 iOS 和应用更新的一些好处。您还将了解如何关闭 iPhone 上的自动更新。
为什么你应该关闭自动(Automatic)更新
iOS 升级的最早或第一个版本通常不稳定且充满错误。所以，我更喜欢在第一次重大升级后更新我的 iPhone 大约两个“点版本”。
“点发布”描述了对主要或现有软件更新的次要和增量更新。点发布通常附带错误修复、安全更新和主要更新中问题的解决方案。
就上下文而言，iOS 14有 16 个版本——iOS 14 是主要升级版本，其余都是点版本。
关闭自动更新还具有节省数据的好处，尤其是在您的互联网计划受到限制或封顶的情况下。iOS 更新有时会遇到千兆字节的数据。如果您的 iPhone 在未经您许可的情况下安装新更新，您将比平时更快地达到数据使用限制。
有时，这并不严重。您可能只想关闭自动更新，因为您还没有准备好过渡到新的操作系统。或者，您可能更喜欢较旧的 iOS 版本而不是最新版本。
如何在 iPhone 上关闭自动更新(Automatic)
禁用自动 iOS 更新会让您坐在驾驶座上。您可以完全自主地决定在 iPhone 上安装哪些 iOS 版本/更新以及何时安装。
- 打开设置(Settings)应用程序并选择常规(General)。
- 点击软件更新(Software Update)。
- 选择自动更新(Automatic Updates)。
- 默认情况下，当您的 iPhone 连接到Wi-Fi(Wi-Fi)网络时，iOS 会自动下载新的软件更新。如果您的 iPhone 正在充电并连接到Wi-Fi ，它还会在夜间自动安装更新。关闭(Toggle)安装 iOS 更新(Install iOS Updates)以阻止您的 iPhone 自动更新。
- 关闭“下载 iOS 更新(Download iOS Updates)”以关闭自动 iOS 更新。这也将禁用安装 iOS 更新(Install iOS Updates)选项。
未经您的批准，您的 iPhone 将不再下载或安装 iOS 更新，即使您已连接到Wi-Fi。
在 iOS 14 中关闭自动更新(Turn Off Automatic Update in iOS 14)
在 iOS 14 中禁用自动更新的步骤和屏幕说明与 iOS 15 和其他 iOS 版本略有不同。
转到设置(Settings)>常规(General)>软件更新(Software Update)>自定义自动更新(Customize Automatic Updates)（或自动更新(Automatic Updates)）并关闭下载 iOS 更新(Download iOS Updates)和安装 iOS 更新(Install iOS Updates)选项。
如何在 iPhone 上手动安装软件更新(Manually Install Software)
要检查 iOS 更新，请转到设置(Settings)>常规(General)和软件更新(Software Update)。等待(Wait)iOS 显示适用于您的 iPhone 的最新软件版本，然后选择下载并安装(Download and Install)以安装更新。
确保(Make)您的 iPhone 已连接到 Wi-Fi 网络。否则，“下载并安装”按钮将灰显。如果您的 iPhone 运行的是最新的 iOS 版本，屏幕上将显示“您的(Your)软件是最新的”消息。
关闭(Turn Off Automatic App)iPhone 上的自动应用更新
iPhone 只能通过Wi-Fi连接下载和安装 iOS 更新。应用程序更新并非如此。iOS App Store可以通过蜂窝网络和(App Store)Wi-Fi连接安装新版本的 iPhone 应用程序。
安装应用更新是许多应用开发者推荐的。但是，如果您的蜂窝/数据计划有上限并且您的 iPhone 上有很多应用程序，(lot of apps on your iPhone)我们不建议这样做。
此外，并非所有应用程序更新都稳定且没有问题。在您的设备上更新应用程序之前，验证新应用程序版本没有错误并且没有问题是一种很好的做法。您不想被有问题的应用程序困住，因为在 iOS 中降级应用程序或安装旧版本并不容易。
我们强烈建议您关闭应用程序自动更新，并在确认应用程序没有问题后手动更新您的应用程序。
打开设置(Settings)，选择应用商店，(App Store,)然后在“自动下载”部分关闭应用(Apps)和应用更新(App Updates)。接下来(Next)，前往“蜂窝数据”部分并关闭自动下载(Automatic Downloads)。
如何在 iPhone 上检查应用程序更新(App Updates)
现在您已禁用自动应用更新，下面介绍如何在 iOS 中手动检查应用更新。
- 打开 App Store 并选择右上角的个人资料图标。(profile icon)
- 滚动到“可用更新”部分，然后点击要更新的应用旁边的更新按钮。(Update)更好的(Better)是，选择全部更新(Update All)以安装所有可用的应用程序更新。
启用低功耗模式
激活低功耗模式(Power Mode)是（暂时）暂停自动 iOS 和应用程序更新的巧妙技巧。iOS 低功耗模式(iOS Low Power Mode)旨在减少 iPhone 上耗电的应用程序和进程。当您启用低功耗模式(Power Mode)时，iOS 会暂时禁用自动下载和其他在后台运行的耗电进程。
要激活低功耗模式，请转到设置(Settings)>电池(Battery)并打开低功耗模式(Low Power Mode)。
更快的选择是打开 iPhone 的控制中心(Control Center)并点击电池图标。电池图标将变为黄色，并且控制中心上将出现“(Control Center)低(Low) 功耗模式(Power Mode)：开启”警报。
如果找不到电池图标，请自定义 iPhone 的控制中心(customize your iPhone’s Control Center)以包含低电量模式(Low Power Mode)。在 iOS 15 中，转到设置(Settings)>控制中心(Control Center)，然后点击低功耗模式(Low Power Mode)旁边的绿色加号图标(green plus icon)。这会将Low Power Mode快捷方式添加到Control Center。
对于运行 iOS 14 或更低版本的 iPhone，请前往“设置”(Settings) > “控制中心(Control Center)” > “自定义控制中心(Customize Control Center)” ，然后选择“低功耗模式”(Low Power Mode)。
当低功耗模式(Low Power Mode)打开时，自动下载(Automatic Downloads)选项会立即禁用并在设置(Settings)菜单中显示为灰色。您应该会在选项下方看到一条消息，上面写着“在低功耗模式下(Low Power Mode)自动下载(Automatic Downloads)不可用”。
注意：(Note:)当您的 iPhone 电量超过 80% 时，iOS 会自动禁用低功耗模式。(Low Power Mode)如果发生这种情况，您需要重新启用低功耗模式(Low Power Mode)。否则(Otherwise)，自动下载和更新将在后台恢复。
手动更新您的 iPhone（和应用程序）(Apps)
在您方便的时候下载更新有助于减少数据使用量、延长电池寿命并确保您在 iPhone 上安装稳定且无错误的软件。同样(Again)，请确保在手动安装任何更新之前执行尽职调查。阅读用户在Apple 支持社区(Apple Support Communities)的体验和反馈，查看App Store评分并阅读其他受信任的技术论坛或网站上的评论。
How to Turn Off Automatic Updates on iPhone
Phones are configured to automatically install software and app updates—although sоme iOS updates have to be installed manually. It’s convenient to have your iPhone and applications update themselves to the latest versions. However, there are instances when manually initiating these updates is more beneficial.
We’ll walk you through some benefits of manually installing iOS and app updates. You’ll also learn how to turn off automatic updates on iPhones.
Why You Should Turn Off Automatic Updates
The earliest or first version of iOS upgrades is often unstable and filled with bugs. So, I prefer to update my iPhone about two “point releases” after the first major upgrade.
A “point release” describes minor and incremental updates to a major or existing software update. Point releases often ship with bug fixes, security updates, and resolutions to issues in the major update.
For context, iOS 14 had 16 versions—iOS 14 was the major upgrade, while the rest were point releases.
Turning off automatic updates also has data-saving benefits, especially if your internet plan is limited or capped. iOS updates sometimes run into gigabytes of data. You’ll hit your data usage limit faster than usual if your iPhone installs new updates without your permission.
Sometimes, it’s nothing serious. You might just want to turn off automatic updates because you aren’t ready to transition to a new operating system. Or perhaps, you prefer an older iOS version to the latest iteration.
How To Turn Off Automatic Updates on iPhone
Disabling automatic iOS updates puts you in the driver’s seat. You get full autonomy over what iOS versions/updates get installed on your iPhone and when they get installed.
- Open the Settings app and select General.
- Tap Software Update.
- Select Automatic Updates.
- iOS, by default, automatically downloads new software updates when your iPhone is connected to a Wi-Fi network. It also automatically installs the update overnight if your iPhone is charging and connected to Wi-Fi. Toggle off Install iOS Updates to stop your iPhone from automatically updating itself.
- Toggle off Download iOS Updates to turn off automatic iOS updates. That’ll also disable the Install iOS Updates option.
Your iPhone will no longer download or install iOS updates without your approval—even if you’re connected to Wi-Fi.
Turn Off Automatic Update in iOS 14
The steps and on-screen instructions for disabling automatic updates in iOS 14 are a little different from iOS 15 and other iOS versions.
Go to Settings > General > Software Update > Customize Automatic Updates (or Automatic Updates) and toggle off both Download iOS Updates and Install iOS Updates options.
How To Manually Install Software Updates on iPhone
To check for iOS updates, go to Settings > General and Software Update. Wait for iOS to display the latest software version available for your iPhone and select Download and Install to install the update.
Make sure your iPhone is connected to a Wi-Fi network. Otherwise, the “Download and Install” button will be grayed out. A “Your software is up to date” message will show up on the screen if your iPhone is running the latest iOS version.
Turn Off Automatic App Updates on iPhone
iPhones download and install iOS updates over Wi-Fi connections only. That isn’t the case with app updates. The iOS App Store can install new versions of your iPhone app over cellular and Wi-Fi connections.
Installing app updates is something many app developers recommend. But it’s not something we recommend if your cellular/data plan is capped and you have a lot of apps on your iPhone.
Additionally, not all app updates are stable and problem-free. It’s good practice to verify that a new app version is bug-free and has no issues before updating the app on your device. You don’t want to be stuck with a problematic app since it’s not exactly easy to downgrade an app or install an older version in iOS.
We strongly advise that you turn off automatic app updates and manually update your apps after verifying that they’re problem-free.
Open Settings, select App Store, and toggle off Apps and App Updates in the “Automatic Downloads” section. Next, head to the “Cellular Data” section and toggle off Automatic Downloads.
How To Check for App Updates on iPhone
Now that you’ve disabled automatic app updates, here’s how to manually check for app updates in iOS.
- Open the App Store and select the profile icon in the top-right corner.
- Scroll to the “Available Updates” section and tap the Update button next to the app you want to update. Better yet, select Update All to install all available app updates.
Enable Low Power Mode
Activating Low Power Mode is a neat trick to (temporarily) pause automatic iOS and app updates. The iOS Low Power Mode is designed to reduce battery-draining apps and processes on iPhone. When you enable Low Power Mode, iOS temporarily disables automatic downloads and other power-hungry processes running in the background.
To activate Low Power Mode, go to Settings > Battery and toggle on Low Power Mode.
A faster alternative is to open your iPhone’s Control Center and tap the battery icon. The battery icon will change to yellow and a “Low Power Mode: On” alert will appear on the Control Center.
If you can’t find the battery icon, customize your iPhone’s Control Center to include Low Power Mode. In iOS 15, go to Settings > Control Center, and tap the green plus icon next to Low Power Mode. That’ll add the Low Power Mode shortcut to the Control Center.
For iPhones running iOS 14 or lower, go to Settings > Control Center > Customize Control Center and select Low Power Mode.
When Low Power Mode is on, the Automatic Downloads options are immediately disabled and grayed out in the Settings menu. You should see a message that reads “Automatic Downloads are not available while in Low Power Mode” below the options.
Note: iOS automatically disabled Low Power Mode when your iPhone charges past 80%. You’ll need to re-enable Low Power Mode if that happens. Otherwise, automatic downloads and updates will resume in the background.
Update Your iPhone (and Apps) Manually
Downloading updates at your convenience helps to reduce data usage, extend battery life, and ensure you’re installing stable and bug-free software on your iPhone. Again, make sure you perform due diligence checks before manually installing any update. Read users’ experiences and feedback on Apple Support Communities, check App Store ratings and read reviews on other trusted tech forums or websites.
