打算卖掉你的 iPhone，把它送人，或者以旧换新？首先^(First)，您应该擦除 iPhone，以便轻松切换到新设备^{(easy to switch to a new device)}。同样^(Likewise)，断开您的Apple帐户与 iPhone 的连接，以便新用户可以毫无问题地激活设备。本教程将向您展示如何在出售或赠送之前正确擦除您的 iPhone。

在你抹掉你的 iPhone 之前

在擦除旧 iPhone 之前，您应该执行以下三项基本操作。

1. 取消配对您的 Apple Watch

如果您有Apple Watch ，请在^{(Apple Watch)}重置 iPhone 或^{(resetting your iPhone or the watch)}手表之前取消与手表的配对。这将禁用激活锁^{(Activation Lock)}，解锁Apple Watch以在不同的 iPhone 上使用。

1. 在 iPhone 上启动Watch应用，然后点击“我的手表”选项卡右上角的所有手表。^{(All Watches)}
2. 点击Apple Watch 旁边的信息图标。^{(info icon)}

1. 轻点“取消配对 Apple Watch^{(Unpair Apple Watch)} ”，然后在出现提示时选择“取消配对 [名称] Apple Watch ”。^{(Unpair [Name] Apple Watch)}
2. 输入您的Apple ID 密码^{(Apple ID password)}，然后点击右上角的取消配对^(Unpair)。

这将取消手表与您的帐户的链接，禁用Activation Lock并删除Find My Watch。

2.注销iMessage和FaceTime

如果您要切换到非 Apple 设备，请先停用 iMessage，然后再抹掉旧 iPhone。否则^(Otherwise)，您的新 ( Android ) 手机可能无法接收通过iOS 设备上的信息^(Messages)应用程序发送的SMS/MMS

在继续之前，请确保与您的 iMessage 电话号码关联的SIM卡在您的 iPhone 中。之后^(Afterward)，将您的 iPhone 连接到蜂窝网络，前往“设置”^(Settings) > “信息^(Messages)” ，然后关闭iMessage。

返回设置^(Settings)菜单，选择FaceTime，然后关闭FaceTime。

如果您无法再访问您的 iPhone，您可以在线停用 iMessage 和FaceTime。

在您的移动或 PC 网络浏览器上访问这个Apple 的自助解决门户。^{(Apple’s Self-Solve portal)}选择您的国家代码并在对话框中输入您要注销的 iMessage/FaceTime 电话号码。选择发送代码^{(Send Code)}以继续。

输入通过SMS^(SMS)发送到电话号码的 6 位数确认码，然后选择提交^(Submit)。如果提供的信息无误，Apple将从 iMessage 服务远程停用您的手机。

3. 关闭查找我的^{(Find My)}iPhone 和激活锁^{(Activation Lock)}

在擦除 iPhone 以进行折价之前，禁用激活锁^{(Activation Lock)}是您需要做的最重要的事情。这会将 iPhone 与您的Apple ID^{(Apple ID)}断开连接，以便购买它的人可以毫无问题地使用该设备。

打开“设置”^(Settings)应用，轻点您的Apple ID名称，选择“查找”^{(Find My)}，然后关闭“查找”^{(Find My)}。接下来，输入您的Apple ID密码并轻点“关闭”^{(Turn Off)}。

1.从iOS设置恢复出厂^(Reset)设置

如果您手动将 iPhone 恢复出厂设置，您可能会忽略某些活动。iOS 15 恢复出厂设置工具会引导您完成整个过程，因此您不会错过任何事情。该工具将禁用激活锁^{(Activation Lock)}，断开您的Apple ID帐户，并在重置您的 iPhone 之前备份您的数据。

如果您的 iPhone 运行 iOS 15 或更高版本，以下是安全执行出厂重置的方法：

1. 打开“设置”^(Settings)应用，轻点“通用^(General)”，然后选择“转移或重置 iPhone^{(Transfer or Reset iPhone)} ” 。
2. 点击删除所有内容和设置^{(Erase All Content and Settings)}。

该工具将显示将从您的 iPhone 中删除的应用程序、个人数据、帐户和服务的摘要。

1. 点击继续^(Continue)并输入您的 iPhone 密码以继续。
2. 将您的 iPhone 连接到 Wi-Fi 网络并等待该工具创建 iCloud 备份。否则，点击跳过备份^{(Skip Backup)}以擦除您的 iPhone 数据而不将其上传到 iCloud。
3. 输入您的 Apple ID 密码，点击关闭^{(Turn Off)}，然后按照下一页上的提示进行操作。

出厂重置非 iOS 15 iPhone

要重置运行 iOS 14 或更早版本的 iPhone，请前往“设置”^(Settings) > “通用^(General)” > “重置^(Reset)” 。输入您的 iPhone 密码、您的Apple ID密码，然后轻点“抹掉所有内容和设置”^{(Erase All Content and Settings)}。

2.从电脑^(Computer)上抹掉你的 iPhone

如果您无法直接从“设置”^(Settings)应用将 iPhone 恢复出厂设置，请改用Mac或Windows计算机。Mac计算机必须至少运行 macOS Catalina 10.15^{(Catalina 10.15)}。如果您使用的是Windows设备，请确保它具有最新版本的 iTunes。

在Mac 电脑^{(Mac Computer)}上恢复出厂设置^(Reset)iPhone

1. 使用USB 数据^(USB)线将您的 iPhone 插入Mac笔记本电脑或台式机。解锁您的 iPhone，并在出现提示时授予计算机访问您的数据和设置的权限。
2. 打开Finder并在边栏中选择您的 iPhone。

将您的应用程序和个人数据备份到您的计算机^{(Back up your apps and personal data to your computer)}，以便您可以将它们恢复到您的新 iPhone。继续下一步以创建旧 iPhone 的备份。如果您不想备份 iPhone，请跳至第 6 步。^(Jump)

1. 前往常规^(General)选项卡，选择备份 iPhone 上的所有数据，^{(Back up all of the data on your iPhone,)}然后选择立即备份^{(Back Up Now)}。

1. 选择^(Select)是否要使用安全密码加密备份。

如果您选择加密备份，请在下一页输入密码并选择Set Password。

1. 输入您的 iPhone 密码（在您的 iPhone 上）开始备份。
2. 备份完成后，滚动到“软件”部分，然后选择恢复 iPhone^{(Restore iPhone)}。

1. 选择备份^{(Back Up)}以在计算机上创建 iPhone 设置的副本。选择不备份^{(Don’t Back Up)}以继续而不备份您的设置。

在 Windows 中恢复出厂设置 iPhone

1. 将 iPhone 连接到Windows PC，打开 iTunes，然后选择左上角的 iPhone 图标。

1. 如果您想在擦除 iPhone 之前对其进行备份，请选择侧边栏上的摘要^(Summary)，然后选择立即备份^{(Back Up Now)}。

1. 选择恢复 iPhone^{(Restore iPhone)}将您的 iPhone 重置为出厂设置。

1. 或者，选择是否要在恢复 iPhone 之前创建 iPhone 设置的 iTunes 备份。

3. 通过恢复模式擦除 iPhone

如果您不记得 iPhone 的密码，请进入恢复模式^{(Recovery Mode)}，然后从Mac或Windows电脑抹掉设备。恢复模式^{(Recovery Mode)}也是擦除无法正确启动的 iPhone 的绝妙方法。

将 iPhone 插入电脑，打开Finder或 iTunes，然后按照以下步骤进入恢复模式^{(Recovery Mode)}：

• iPhone 8 机型、iPhone SE（第 2 代）和其他配备面容 ID 的 iPhone：^{(iPhone 8 models, iPhone SE (2nd generation), and other iPhones with Face ID:)}按下并松开提高音量^{(Volume Up)}。然后，按下并释放降低音量^{(Volume Down)}按钮。最后，按住侧面按钮^{(Side button)}，直到手机启动进入恢复模式。

• iPhone 7 机型和 iPod touch（第 7 代）：^{(iPhone 7 models and iPod touch (7th generation):)}按住侧面^(Side)（或顶部^(Top)）按钮和降低音量^{(Volume Down)}按钮，直到出现恢复模式屏幕。
• 较旧的 iPhone 和 iPod touch：^{(Older iPhones and iPod touch:)}按住主^(Home)屏幕按钮和侧面^(Side)（或顶部^(Top)）按钮，直到您的设备启动恢复模式屏幕。

当您的设备启动恢复时，Finder或 iTunes 应该会显示一个弹出窗口，提示您的 iPhone 存在问题。选择恢复^(Restore)以继续。

如果您的电脑有互联网连接，Finder或 iTunes 将在您的 iPhone 恢复出厂设置后安装最新版本的 iOS。选择恢复和更新^{(Restore and Update)}以继续。

准备出售

我们不建议远程擦除您想要以旧换新的 iPhone 。^{(remotely erasing an iPhone)}Apple将擦除 iPhone，但保持激活锁^{(Activation Lock)}处于启用状态，因为它假定您的设备丢失或被盗。始终^(Always)从设置菜单或使用计算机将 iPhone 恢复出厂设置。之后，使用Find My服务确认 iPhone 的激活锁^{(Activation Lock)}状态。

如果将 iPhone 恢复出厂设置后激活锁仍然有效，请联系^{(Activation Lock)}Apple 支持^{(Apple Support)}以获取激活锁支持请求^{(Activation Lock support request)}。

3 Ways to Erase Your Old iPhone Before Trading It In

Planning to sell yоur iPhone, give it away, or trade it in for a new model? First, you should erase the iPhone to make it easy to switch to a new device. Likewise, disconnect your Apple account from the iPhone so that the new user can activate the device without issues. This tutorial will show you how to erase your iPhone correctly before selling or giving it away.

Before You Erase Your iPhone

Here are three essential things you should do before erasing your old iPhone.

1. Unpair Your Apple Watch

If you have an Apple Watch, unpair the watch before resetting your iPhone or the watch. That will disable Activation Lock, unlocking the Apple Watch for use on a different iPhone.

1. Launch the Watch app on your iPhone and tap All Watches in the top-right corner of the ”My Watch” tab.
2. Tap the info icon next to your Apple Watch.

1. Tap Unpair Apple Watch and select Unpair [Name] Apple Watch on the prompt.
2. Enter your Apple ID password and tap Unpair in the top-right corner.

That will unlink the watch from your account, disable Activation Lock, and remove Find My Watch.

2. Deregister iMessage and FaceTime

If you’re switching to a non-Apple device, deactivate iMessage before erasing your old iPhone. Otherwise, your new (Android) phone may not receive SMS/MMS sent via the Messages app on iOS devices.

Before proceeding, ensure the SIM card associated with your iMessage phone number is in your iPhone. Afterward, connect your iPhone to a cellular network, go to Settings > Messages, and toggle off iMessage.

Return to the Settings menu, select FaceTime, and toggle off FaceTime.

If you no longer have access to your iPhone, you can deactivate iMessage and FaceTime online.

Visit this Apple’s Self-Solve portal on your mobile or PC web browser. Select your country code and enter the iMessage/FaceTime phone number you want to deregister in the dialog box. Select Send Code to proceed.

Enter the 6-digit confirmation code sent to the phone number via SMS and select Submit. If the information provided checks out, Apple would remotely deactivate your phone from the iMessage service.

3. Turn Off Find My iPhone and Activation Lock

Disabling Activation Lock is the most important thing you need to do before erasing your iPhone for trade-in. That disconnects the iPhone from your Apple ID so that whoever buys it can use the device without any issue.

Open the Settings app, tap your Apple ID name, select Find My, and turn off Find My. Next, enter your Apple ID password and tap Turn Off.

1. Factory Reset iPhone from iOS Settings

If you manually factory reset your iPhone, you may omit certain activities. The iOS 15 factory reset tool guides you through the entire process so you don’t miss anything. The tool will disable Activation Lock, disconnect your Apple ID account, and back up your data before resetting your iPhone.

If your iPhone runs iOS 15 or newer, here’s how to securely perform a factory reset:

1. Open the Settings app, tap General, and select Transfer or Reset iPhone.
2. Tap Erase All Content and Settings.

The tool will display a summary of apps, personal data, accounts, and services that it will remove from your iPhone.

1. Tap Continue and enter your iPhone’s passcode to proceed.
2. Connect your iPhone to a Wi-Fi network and wait for the tool to create an iCloud backup. Otherwise, tap Skip Backup to erase your iPhone data without uploading it to iCloud.
3. Enter your Apple ID password, tap Turn Off, and follow the prompt on the next page.

Factory Reset Non-iOS 15 iPhones

To reset an iPhone running iOS 14 or older, go to Settings > General > Reset. Enter your iPhone’s passcode, your Apple ID password, and tap Erase All Content and Settings.

2. Erase Your iPhone from a Computer

If you can’t factory reset your iPhone directly from the Settings app, use a Mac or Windows computer instead. The Mac computer must be running at least macOS Catalina 10.15. If you’re using a Windows device, ensure it has the latest version of iTunes.

Factory Reset iPhone on a Mac Computer

1. Plug your iPhone into a Mac notebook or desktop with a USB cable. Unlock your iPhone and—if prompted—grant the computer access to your data and settings.
2. Open Finder and select your iPhone on the sidebar.

Back up your apps and personal data to your computer so that you can restore them to your new iPhone. Proceed to the next step to create a backup of your old iPhone. Jump to step #6 if you don’t want to back up the iPhone.

1. Head to the General tab, select Back up all of the data on your iPhone, and select Back Up Now.

1. Select whether or not you want to encrypt the backup with a security password.

If you choose to encrypt the backup, enter a password on the next page and select Set Password.

1. Enter your iPhone’s passcode (on your iPhone) to start the backup.
2. Scroll to the “Software” section when the backup is complete and select Restore iPhone.

1. Select Back Up to create a copy of your iPhone’s settings on the computer. Select Don’t Back Up to proceed without backing up your settings.

Factory Reset iPhone in Windows

1. Connect the iPhone to your Windows PC, open iTunes, and select the iPhone icon in the top-left corner.

1. If you want to backup your iPhone before erasing it, select Summary on the sidebar, and select Back Up Now.

1. Select Restore iPhone to reset your iPhone to factory settings.

1. Optionally, choose whether or not you want to create an iTunes backup of your iPhone’s settings before restoring the iPhone.

3. Erase iPhone via Recovery Mode

If you can’t remember your iPhone’s passcode, enter Recovery Mode, then erase the device from a Mac or Windows computer. Recovery Mode is also a nifty route to erase an iPhone that won’t boot correctly.

Plug your iPhone into your computer, open Finder or iTunes, and follow the steps below to enter Recovery Mode:

• iPhone 8 models, iPhone SE (2nd generation), and other iPhones with Face ID: Press and release the Volume Up. Afterward, press and release the Volume Down button. Finally, press and hold the Side button until your phone boots into recovery mode.

• iPhone 7 models and iPod touch (7th generation): Press and hold the Side (or Top) button and Volume Down button until the recovery mode screen appears.
• Older iPhones and iPod touch: Press and hold the Home button and Side (or Top) button until your device boots the recovery mode screen.

When your device boots into recovery, Finder or iTunes should display a pop-up that there’s a problem with your iPhone. Select Restore to proceed.

If your computer has an internet connection, Finder or iTunes will install the latest version of iOS on your iPhone after the factory reset. Select Restore and Update to proceed.

Ready to Be Sold

We don’t recommend remotely erasing an iPhone that you want to trade-in. Apple will erase the iPhone but keep Activation Lock enabled because it assumes your device is lost or stolen. Always factory reset your iPhone from its settings menu or use a computer. After that, use the Find My service to confirm the iPhone’s Activation Lock status.

If Activation Lock remains active after factory resetting your iPhone, contact Apple Support for an Activation Lock support request.
