没有什么比性能不佳的 iPhone 更令人沮丧的了。您的 iPhone因各种原因出现速度变慢(experiences slowdowns)，包括安装的应用程序过多、存储空间堵塞、软件问题等。
幸运的是，您可以快速修复大多数这些项目并加快您的 iOS 设备的运行速度。我们将研究一些修复慢速 iPhone 的方法。
1. 重启你的 iPhone
当你的 iPhone 变得迟钝时，首先要做的就是重启你的手机(reboot your phone)。这样做会清除手机的临时内存并让系统重新开始。
您可以通过同时按下提高音量或降低音量(Down)以及侧边(Side)按钮来重新启动 iPhone X、11、12 或 13 。然后，拖动滑块，您的手机将关机。然后，按住侧面(Side)按钮打开手机。
如果您使用的是 iPhone SE（第 2 代或第 3 代）、8、7 或 6，请按住侧边(Side)按钮并拖动滑块来关闭手机。然后，按住侧面(Side)按钮重新打开手机。
您可以通过按住顶部按钮并拖动滑块来重新启动较旧的 iPhone 型号，例如 iPhone SE（第 1 代）、5 和更早版本。然后，按住顶部按钮重新打开手机。
2. 为什么我的 iPhone 很慢(Slow)？因为您有未使用的应用程序(Apps)正在运行
同时运行的多个应用程序可能会导致您的 iPhone 变慢。所有这些应用程序同时使用您手机的资源，从而减少每个应用程序的可用内存。
因此，我们建议您关闭(keep the unused apps closed)iPhone 上未使用的应用程序。您可能希望在每次使用完应用程序后退出它们。您可以通过打开应用切换器并向上滑动要关闭的应用来退出应用。
3. 更新您的Apple iPhone 的 iOS版本(Version)
过时的软件版本可能会导致许多问题，包括降低 iPhone 的速度。因此，您应该保持 iPhone 的操作系统更新，以始终拥有最新的错误补丁。
您可以轻松地将 iPhone 更新(update your iPhone)到最新版本的 iOS。这些更新始终免费且易于下载和安装。
- 打开 iPhone 上的设置。
- 选择常规(Select General)，然后选择软件更新(Software Update)。
- 让您的 iPhone 检查最新的 iOS 更新。
- 选择下载(Choose Download)并安装(Install)以安装最新更新。
4. 清除Safari中的历史记录(History)和网站数据(Website Data)
Safari 的性能问题(Safari’s performance issues)通常与您的浏览历史记录和网站数据有关。您的浏览器会保存您的所有浏览会话和其他项目，例如 cookie。
随着时间的推移，Safari会积累许多此类项目，从而导致浏览器性能下降。幸运的是，您可以通过清除(clearing your data)浏览器中的数据来解决此问题。
- 在 iPhone 上启动设置。
- 向下滚动(Scroll)并点击Safari以访问您的浏览器设置。
- 在Safari页面上选择清除历史记录(Clear History)和网站数据。(Website Data)
- 在打开的提示中选择清除历史记录和数据。(Data)
如果您在这些应用程序中遇到迟缓，请清除其他 iPhone 网络浏览器中的数据。
5.从你的 iPhone 中
删除不需要的文件(Delete)
现代 iPhone 提供大量存储空间，因此您不太可能耗尽存储空间。但是，您可以通过拍摄新照片、录制视频和从 Internet 下载文件来耗尽手机的空间。
存储空间不足可能会导致您的 iPhone 变慢，因为您的手机没有空间来存储临时物品。在这些情况下，从您的 iPhone 中查找并删除不需要的文件以释放您的存储空间(free up your storage)。
例如，以下是删除 iPhone 上占用内存的照片和视频的方法：
- 在 iPhone 上启动照片(Photos)应用程序。
- 选择您不想保留的照片和视频。
- 点击位于右下角的垃圾桶图标。
- (Choose Delete)在打开的提示中选择删除。
- 导航(Navigate)到Albums > Recently Deleted并从此处删除您的文件。
6. 卸载iPhone
上不需要的(Your)应用程序(Apps)
就像您的照片和视频一样，请考虑删除您未使用的应用程序，以便您拥有一款整洁且性能快速的 iPhone。您可能出于各种原因想要删除应用程序(remove an app for various reasons)，包括您是否找到了更好的替代方案、是否更喜欢使用该应用程序的网络版本或不想再使用该应用程序。
删除不需要的应用程序(Deleting unwanted apps)可使您的主屏幕保持整洁并释放您的 iPhone 存储空间。
- 在 iPhone 的主屏幕上找到要删除的应用程序。
- 点击(Tap)并按住您的应用程序，直到您的所有应用程序图标开始杂耍。
- 选择您要删除的应用左上角的 X。
- 在提示中选择删除(Choose Delete)以删除选定的应用程序。
重复上述过程以从您的 iPhone 中删除其他应用程序。
7.关闭后台应用刷新(Background App Refresh)和定位(Location)服务
您的 iPhone 允许您安装的应用程序和系统功能在后台执行刷新。这会给您的手机资源带来负担，导致您的手机性能低下。
您的应用程序还可以访问位置数据，这也会降低您的设备速度。
在这些情况下，您可以关闭iPhone 上的后台应用刷新(Background App Refresh)和定位(Location) 服务(Services)，以提高手机的性能。但是，这样做可能会影响使用上述服务的应用程序的功能。
- 访问iPhone 上的“设置”应用。(Settings)
- 前往“设置”(Settings)中的“General > Background App Refresh” 。
- (Tap Background App Refresh)点击顶部的后台应用刷新。
- 选择关闭选项。
- 返回设置的主屏幕并点击隐私(Privacy)。
- 在随后的页面上选择定位(Select Location) 服务(Services)。
- 关闭顶部的定位服务选项。(Services)
8. 减少 iPhone 的动画(Animation)效果
您的 iPhone 在导航菜单时会播放各种动画(Your iPhone plays various animations)，为您提供流畅的体验。这些动画依赖于您手机的资源来提供输出。
减少这些动作是个好主意，这样您的 iPhone 就有更多资源可用于您的基本任务。但是，关闭这些动画后，您的 iPhone 外观不会发生巨大变化。
- 打开 iPhone 上的设置。
- Access General > Accessibility > Reduce Motion在“设置”中(Settings)访问“通用”>“辅助功能”>“减少运动” 。
- 打开减少运动选项。
9. 重置iPhone

Why Is My iPhone So Slow? 9 Ways to Speed It Up
There’s nothing more frustrating than an iPhone that performs poorly. Your iPhone experiences slowdowns for various reasons, including too many installed apps, clogged-up storage, software problems, etc.
Fortunately, you can quickly fix most of those items and speed up your iOS device. We’ll look at some of the ways to fix a slow iPhone.
1. Reboot Your iPhone
When your iPhone becomes sluggish, the first thing to do is reboot your phone. Doing so clears your phone’s temporary memory and gives the system a fresh start.
You can restart an iPhone X, 11, 12, or 13 by pressing either Volume Up or Volume Down and the Side button simultaneously. Then, drag the slider, and your phone will power off. Then, power on your phone by pressing and holding down the Side button.
If you have an iPhone SE (2nd or 3rd generation), 8, 7, or 6, turn off your phone by pressing and holding down the Side button and dragging the slider. Then, power the phone back on by pressing and holding down the Side button.
You can reboot older iPhone models, like the iPhone SE (1st generation), 5, and earlier, by pressing and holding down the Top button and dragging the slider. Then, turn your phone back on by pressing and holding down the Top button.
2. Why Is My iPhone Slow? Because You Have Unused Apps Running
Several apps running at the same time can cause your iPhone to slow down. All these apps use your phone’s resources simultaneously, leaving less memory available to each app.
Therefore, we recommend you keep the unused apps closed on your iPhone. You might want to quit your apps each time you finish using them. You can exit an app by opening the app switcher and swiping up on the app you want to close.
3. Update Your Apple iPhone’s iOS Version
Outdated software versions can cause many issues, including slowing down your iPhone. So, you should keep your iPhone’s operating system updated to always have the latest bug patches.
You can update your iPhone to the latest version of iOS in a hassle-free way. These updates are always free and easy to download and install.
- Open Settings on your iPhone.
- Select General followed by Software Update.
- Allow your iPhone to check for the latest iOS updates.
- Choose Download and Install to install the latest updates.
4. Clear History and Website Data in Safari
Safari’s performance issues are usually linked to your browsing history and website data. Your browser saves all your browsing sessions and other items, like cookies.
Over time, Safari accumulates many of these items, causing the browser performance to decline. Luckily, you can fix the issue by clearing your data in the browser.
- Launch Settings on your iPhone.
- Scroll down and tap Safari to access your browser settings.
- Select Clear History and Website Data on the Safari page.
- Choose Clear History and Data in the prompt that opens.
Clear data in your other iPhone web browsers if you experience sluggishness in those apps.
5. Delete Unwanted Files From Your iPhone
Modern iPhones offer a generous amount of storage, so you’re less likely to run out of storage space. However, you can exhaust your phone’s space by taking new photos, recording videos, and downloading files from the internet.
The lack of storage can cause your iPhone to slow down, as your phone has no space to store temporary items. In these cases, find and remove the unwanted files from your iPhone to free up your storage.
For example, here’s how you can delete your memory-hogging photos and videos on your iPhone:
- Launch the Photos app on your iPhone.
- Select the photos and videos you don’t want to keep.
- Tap the trash can icon located at the bottom-right corner.
- Choose Delete in the prompt that opens.
- Navigate to Albums > Recently Deleted and delete your files from here as well.
6. Uninstall Unwanted Apps on Your iPhone
Like your photos and videos, consider deleting your unused apps so you have a decluttered and fast-performing iPhone. You may want to remove an app for various reasons, including whether you’ve found a better alternative, prefer to use the app’s web version or don’t wish to use the app anymore.
Deleting unwanted apps keeps your home screen neat and frees up your iPhone storage.
- Find the app to delete on your iPhone’s home screen.
- Tap and hold on your app until all your app icons start juggling.
- Select X at the top-left corner of the app you want to delete.
- Choose Delete in the prompt to remove the selected app.
Repeat the above process to delete other apps from your iPhone.
7. Turn Off Background App Refresh and Location Services
Your iPhone allows your installed apps and system functions to perform refreshes in the background. This puts a load on your phone’s resources, causing your phone to deliver a sluggish performance.
Your apps can also access location data which also slows down your device.
In these cases, you can turn off both Background App Refresh and Location Services on your iPhone to improve your phone’s performance. However, doing so may affect the functionality of the apps that use the services mentioned above.
- Access the Settings app on your iPhone.
- Head to General > Background App Refresh in Settings.
- Tap Background App Refresh at the top.
- Choose the Off option.
- Go back to Settings’ main screen and tap Privacy.
- Select Location Services on the page that follows.
- Turn off the Location Services option at the top.
8. Reduce Your iPhone’s Animation Effects
Your iPhone plays various animations when navigating the menus to give you a fluid experience. Those animations rely on your phone’s resources to deliver the output.
It’s a good idea to reduce these motions so that your iPhone has more resources available for your essential tasks. However, you shouldn’t experience a huge change in your iPhone’s appearance when turning off these animations.
- Open Settings on your iPhone.
- Access General > Accessibility > Reduce Motion in Settings.
- Turn on the Reduce Motion option.
9. Reset All Settings on Your iPhone
Improperly configured settings can also cause your iPhone to slow down. If you don’t remember changing a setting option, you can reset your settings to the factory defaults. This fixes all the setting-related issues on your iPhone.
You can customize your settings from scratch once you’ve reset them.
- Access Settings on your iPhone.
- Choose General > Reset in Settings.
- Tap Reset All Settings.
- Authenticate yourself, and your iPhone will proceed to reset.
Boost Your iPhone’s Performance Using Several Ways
You’ll likely have to follow multiple methods outlined above before your phone starts to perform better. Then, once your phone is back in action, ensure you don’t install unnecessary items so that it continues to run smoothly.
