iPhone 提供了各种数据类型的清晰图片——消息、应用程序、照片等等——填满了它的内部存储空间。您可以随时通过转到Settings > General > iPhone Storage来查看。
iPhone 存储屏幕顶部的视觉指示器可以让您在管理存储时专注于影响最大的区域。但是您还会看到一个数据类别——令人困惑地——标记为“其他”，占用了 iPhone 上的空间。
iPhone 上的“其他”存储是什么？
iPhone 上的“其他”存储包括各种数据形式（例如日志、文件索引和应用程序缓存），iPhone 的操作系统（iOS）使用这些数据形式来保持功能正常运行。然而，缓存的应用程序数据几乎总是构成该存储的大部分。
您可以通过向下滚动 iPhone 存储屏幕来查看 iPhone 上“其他”存储的确切数量。通常会在 2-5GB 范围内找到“其他”，并且在您使用 iPhone 时它应该会增加和减少。
iOS 足够聪明，可以管理应用程序缓存，而不会让它们失去控制。例如，假设您开始通过 Netflix(streaming video via Netflix)或Apple TV流式传输视频。您的 iPhone 将在本地缓存该内容，这将导致“其他”存储空间增加。但是，一旦您完成观看，iOS 将刷新该数据。
但是，在极少数情况下，事情可能会失控，“其他”存储最终可能会达到两位数。如果您的空间快用完，您应该尝试减少 iPhone 上的“其他”存储空间。
如何减少“其他”存储
iOS 没有提供用于释放 iPhone 上的“其他”存储空间的内置选项。但是，您可以使用以下建议。这些将帮助您删除缓存的应用程序数据，从而减少“其他”存储空间。
删除 Safari 中的浏览器缓存(Delete the Browser Cache in Safari)
如果您使用 Safari 进行大量网页浏览(web browsing using Safari)，那么您的 iPhone 应该已经积累了大量的缓存站点数据。iOS 将几乎所有这些都归类为“其他”数据，因此您可以通过清除这些数据来收回数百兆字节（在大多数情况下）。
首先打开iPhone 上的“设置”应用。(Settings )然后，选择Safari并选择Clear History and Website Data以删除Safari中缓存的浏览数据。
清除其他应用的缓存(Clear Caches of Other Apps)
除了Safari之外，您还可以尝试清除其他应用程序的缓存。但是，由于 iOS 能够自动处理缓存数据，iPhone 上的大多数本地和第三方应用程序不提供该选项。
罕见的例外包括OneDrive，您可以在其中通过应用程序的设置(Settings)页面清除缓存。如果您已经知道任何此类应用程序，请清除它们的缓存并查看是否有帮助。
您将在下面了解可用于清除任何应用程序缓存的解决方法。
删除邮件附件(Delete Message Attachments)
如果您经常使用 iMessage，那么您的 iPhone 可能会以视频、音频信息和文档的形式积累大量附件。iPhone 存储屏幕确实有一个单独的消息(Messages)类别，但 iOS 将其中一些数据计为“其他”。
您可以尝试删除较大的 iMessage 附件以减少“其他”存储空间。前往“设置”(Settings ) > “通用(General )” > “ iPhone 存储(iPhone Storage )” > “信息(Messages)” 。然后，选择查看大附件(Review Large Attachments )并删除任何您不想要的。您可以向右滑动附件并选择“删除(Delete)”或使用“编辑(Edit )”选项来批量删除项目。
您还可以将 iPhone 配置为在定义的时间后删除消息（包括附件）。转到设置(Settings )>消息，然后根据需要在(Messages )1 年(1 Year)和30 天(30 Days)之间进行选择。这应该有助于限制未来的“其他”存储。
卸载不需要的应用程序(Offload Unwanted Apps)
尽管您无法直接清除大多数应用程序中的缓存，但您可以尝试卸载它们作为解决方法。这摆脱了应用程序及其相关缓存，而无需删除本地文件或文档(without deleting local files or documents)。然后，您可以稍后重新下载应用程序并从上次中断的地方继续，因此尝试此操作没有任何不利之处。
前往“设置”(Settings ) > “通用(General )” > “ iPhone 存储(iPhone Storage)” 。然后，选择一些非必要的应用程序并选择Offload App。如果这对“其他”存储有影响，请继续卸载更多应用程序。
卸载应用程序后，您将继续在主(Home)屏幕或应用程序库(App Library)上看到其图标。只需(Simply)点按它即可随时重新下载该应用程序。
您还可以将 iPhone 配置为卸载很长时间未使用的应用程序。前往Settings > App Store并打开(App Store )Offload Unused Apps旁边的开关。如果您的 iPhone 上安装了许多应用程序，那么应该可以控制“其他”存储以及 iPhone 上的其他存储。
使用存储建议(Use Storage Recommendations)
有时，您会在 iPhone 存储屏幕中看到一项或多项存储建议，以帮助您释放空间。您已经了解了上面的一些内容——减少大型 iMessage 附件和卸载应用程序——这会影响“其他”存储。
尝试更多——例如与照片(Photos)应用程序相关的那些——并检查这是否会进一步减少“其他”。
强制重启设备(Force-restart Device)
强制重启 iPhone 可以解决异常大的“其他”存储背后的任何故障和异常。要执行强制重启，请根据您的设备型号按下以下按钮组合。
- iPhone 8 和更新(iPhone 8 and Newer)版本：快速按下并松开音量增大(Volume Up)按钮，然后按下音量减小(Volume Down)按钮。立即按住侧边(Side )按钮，直到屏幕上显示Apple标志。
- 仅限 iPhone 7 系列(iPhone 7 Series Only)：同时按住降低音量(Volume Down )和侧边(Side )按钮，直到Apple标志在 iPhone 屏幕上弹出。
- iPhone 6s 及更早机型(iPhone 6s and Older)：按住主(Home )屏幕按钮和侧边(Side )按钮，直到看到Apple标志。
更新 iOS(Update iOS)
与 iPhone 系统软件相关的错误和技术问题是另一个可能导致“其他”数据类别比平时占用更多空间的原因。应用最新的 iOS 更新可能有助于解决这个问题。
前往“设置”(Settings ) > “通用(General )” > “存储(Storage )” ，然后选择“下载并安装(Download and Install)”以将待处理的系统软件更新应用到您的 iPhone。
更新应用(Update Apps)
同样，您还应该应用任何应用程序更新。长按iPhone主(Home)屏幕上的App Store图标并选择更新(Updates )以更新 iPhone 的应用程序。
备份还原(Backup and Restore)
如果您正在处理 iPhone 上臃肿的“其他”存储，您应该考虑将您的 iPhone 重置为出厂设置(resetting your iPhone to factory settings)。这应该允许设备从最少量的“其他”存储开始，同时解决导致它首先出现流氓的任何潜在问题。
在开始之前，请确保create an iCloud or an iTunes/Finder backup。然后，转到设置(Settings )>常规(General )>重置(Reset )并选择擦除所有内容和设置(Erase All Content and Settings)。
在您的 iPhone 完成将自身恢复到出厂设置后，请在设置设备以恢复数据时使用“从 iCloud 备份(Restore from iCloud Backup)恢复/从 Mac 或 PC 恢复”选项。(Restore from Mac or PC)
你无法摆脱这一切
尽管没有可靠的方法来减少 iPhone 上的“其他”存储空间，但上面的大多数建议应该可以帮助你减少它。
但是，如果您的 iPhone 有大量可用存储空间，则没有理由担心“其他”存储空间。随它去吧，iOS 将自行管理一切。
What Is Other Storage on iPhone and How to Reduce It
The iPhone provides a clear picture of the varіous data types—messages, apps, photos, and sо оn—that fill up its internal storage. You can see that whenevеr you want by headіng over to Settings > General > iPhone Storage.
The visual indicator at the top of the iPhone Storage screen makes it possible to focus on areas with the most significant impact when managing storage. But you’ll also see a data category labeled—confusingly—as “Other” using up space on your iPhone.
What Is “Other” Storage on iPhone?
“Other” storage on your iPhone consists of miscellaneous data forms (such as logs, file indexes, and app caches) that the iPhone’s operating system—iOS—uses to keep things functional. Cached app data, however, almost always comprise the bulk of that storage.
You can view the exact amount of “Other” storage on your iPhone by scrolling down the iPhone Storage screen. It’s typical to find “Other” somewhere around the 2-5GB range, and it should increase and decrease as you use your iPhone.
iOS is smart enough to manage app caches without letting them balloon out of control. For example, let’s assume that you started streaming video via Netflix or Apple TV. Your iPhone will cache that content locally, which will cause “Other” storage to increase. But, iOS will flush that data once you’ve finished watching.
On rare occasions, though, things can spiral out of control, and “Other” storage may end up moving into the double digits. You should try to reduce “Other” storage on your iPhone if you’re close to running out of space.
How to Reduce “Other” Storage
iOS provides no built-in options geared toward freeing up “Other” storage on your iPhone. You can, however, use the suggestions below. These will help you delete cached app data, which reduces “Other” storage as well.
Delete the Browser Cache in Safari
If you do lots of web browsing using Safari, then your iPhone should’ve accumulated a sizable chunk of cached site data. iOS categorizes almost all of that as “Other” data, so you can claim back several hundred megabytes—in most cases—by clearing that out.
Start by opening the Settings app on your iPhone. Then, pick Safari and select Clear History and Website Data to remove cached browsing data in Safari.
Clear Caches of Other Apps
In addition to Safari, you can also try clearing the caches of other apps. However, most native and third-party apps on iPhone don’t offer that as an option due to iOS’s ability to handle cached data automatically.
Rare exceptions include OneDrive, where you can clear the cache via the app’s Settings page. If you already know of any such apps, clear their caches and see if that helps.
You’ll learn about a workaround that you can use to clear the cache of any app further below.
Delete Message Attachments
If you use iMessage frequently, the chances are that your iPhone has lots of attachments accumulated in the form of videos, audio messages, and documents. The iPhone Storage screen does have a separate Messages category, but iOS counts some of that data as “Other.”
You can try deleting large iMessage attachments to reduce “Other” storage. Go to Settings > General > iPhone Storage > Messages. Then, select Review Large Attachments and delete any that you don’t want. You can swipe an attachment to the right and select Delete or use the Edit option to remove items en masse.
You can also configure your iPhone to delete messages (including attachments) after a defined amount of time. Go to Settings > Messages and select between 1 Year and 30 Days as needed. That should help keep a lid on “Other” storage going forward.
Offload Unwanted Apps
Although you can’t clear the caches in most apps directly, you can try offloading them as a workaround. That gets rid of the apps—and their related caches—without deleting local files or documents. You can then re-download the apps later and pick up where you left off, so there’s no downside to trying this.
Go to Settings > General > iPhone Storage. Then, pick a few non-essential apps and select Offload App. If that makes a difference to “Other” storage, continue to offload more apps.
After offloading an app, you’ll continue to see its icon on the Home screen or the App Library. Simply tap it to re-download the app whenever you want.
You can also configure your iPhone to offload apps that you’ve not used for a long time. Go to Settings > App Store and turn on the switch next to Offload Unused Apps. If you have lots of apps installed on your iPhone, that should keep “Other” storage—as well as the other storage on your iPhone in general—under control.
Use Storage Recommendations
From time to time, you’ll see one or more storage recommendations within the iPhone Storage screen that helps you free up space. You’ve already learned about a couple of them above—reducing large iMessage attachments and offloading apps—that affect “Other” storage.
Try out more—such as those related to the Photos app—and check if that reduces “Other” even further.
Force-restart Device
Force-restarting an iPhone can resolve any glitches and anomalies behind an unusually large “Other” storage. To perform a force restart, press the button combinations below according to the model of your device.
- iPhone 8 and Newer: Quickly press and release the Volume Up button, and then the Volume Down button. Immediately follow by holding down the Side button until the Apple logo shows on the screen.
- iPhone 7 Series Only: Press and hold both the Volume Down and the Side buttons until the Apple logo pops up on the iPhone’s screen.
- iPhone 6s and Older: Press and hold both the Home and the Side buttons until you see the Apple logo.
Update iOS
Bugs and technical issues related to the iPhone’s system software are another reason that can cause the “Other” data category to consume more space than usual. Applying the latest iOS updates may help fix that.
Go to Settings > General > Storage and select Download and Install to apply pending system software updates to your iPhone.
Update Apps
In the same vein, you should also apply any app updates. Long-press the App Store icon on the iPhone’s Home screen and select Updates to update your iPhone’s apps.
Backup and Restore
If you’re dealing with a bloated “Other” storage on iPhone, you should consider resetting your iPhone to factory settings. That should allow the device to start with the least amount of “Other” storage while simultaneously resolving any underlying issues that caused it to go rogue in the first place.
Before starting, make sure to create an iCloud or an iTunes/Finder backup. Then, go to Settings > General > Reset and select Erase All Content and Settings.
After your iPhone finishes restoring itself to factory settings, use the Restore from iCloud Backup/Restore from Mac or PC options while setting up your device to restore your data.
You Can’t Get Rid Of It All
Although there are no sure-fire ways to reduce “Other” storage on your iPhone, most of the suggestions above should help you cut it down.
However, if your iPhone has lots of free storage available, there’s no reason to concern yourself with “Other” storage. Just leave it be, and iOS will manage everything of its own accord.
