如果您准备出售旧 iPhone，则应注意一些基础知识，以确保您可以无缝切换到新设备。无论是切换到新的Android手机还是新的 iPhone，本指南都将涵盖您在出售旧 iPhone 之前应该做的所有事情。
取消配对 Apple Watch(Unpair Apple Watch)和其他蓝牙(Bluetooth)配件
当您准备出售旧 iPhone 时，应首先取消与 iPhone 配对的配件。如果这些是Apple AirPods等(Apple AirPods)蓝牙(Bluetooth)配件，您可以前往Settings > Bluetooth，然后点击配件名称旁边的 i 按钮。然后，在下一页上，点击忘记(Forget)此设备(Device)以取消配对。
对与您的Apple(Apple)设备
配对的所有蓝牙(Bluetooth)配件执行相同的步骤。
要取消配对Apple Watch，请确保您已佩戴它，并且它已解锁并与您的 iPhone 配对。然后，您可以在 iPhone 上打开Apple Watch应用。转到我的手表(My Watch)选项卡并选择所有手表(Watches)。轻点Apple Watch(Apple Watch)旁边的 I 按钮，然后选择Unpair Apple Watch。
如果您的GPS + Cellular Apple Watch带有来自 AT&T 等运营商的移动数据套餐，您会看到一个提示，询问您是否要保留蜂窝套餐。
如果您打算继续使用手表或换用新的GPS + Cellular Apple Watch，您应该保留它。如果没有，您应该删除该计划。
在此阶段，您可能会被要求使用您的 iPhone 输入您的Apple ID密码。这是为了禁用Apple Watch(Apple Watch)上的激活锁。当您执行此操作时，您的 iPhone 将开始备份Apple Watch的数据并取消与手表的配对。
备份你的 iPhone
处理好配件后，是时候备份旧手机上的所有内容了(back up everything on your old phone)。您可以使用 iCloud Backup将您的数据保存在Apple的云存储服务中。如果您要换用另一部 iPhone 或 iPad，iCloud Backup仍然是在(Backup)Apple产品
之间备份和恢复数据的最简单服务。
您应该首先将您的 iOS 设备连接到 Wi-Fi 网络以使用 iCloud。然后打开 iPhone 上的设置(Settings)应用程序并导航到 [您的姓名] > iCloud > iCloud备份(Backup)。选择(Select Back Up)立即备份以启动 iCloud备份(Backup)。
备份完成后，进度条将消失，您将在“立即备份”(Back Up)按钮下方看到最近的时间戳。
您应该知道，使用 iCloud Backup进行的完整设备备份仅在(Backup)Apple服务器上存储180 天。因此，如果您打算购买一部新手机（例如 iPhone 13）来替换旧手机，请务必在从旧 iPhone 获取最后一次备份后的六个月内从备份中恢复。
如果您想要更永久的备份，您可以使用Mac或 PC 对您的 iPhone 进行完整备份。如果您有 macOS Catalina或新版本的操作系统，请使用 iPhone 随附的充电线将 iPhone 连接到Mac 。在Mac上打开Finder ，然后从左侧边栏中选择 iPhone。
在备份(Backups)下选择立即备份(Back)开始将所有个人数据从 iPhone 存储到Mac。
您还可以通过选择“加密本地备份”(Encrypt Local Backup)选项来选择使用密码加密备份。确保您已将此密码保存在密码管理器中，因为如果您忘记它，您将无法访问您的 iPhone 备份。
此外，如果您想从Apple Watch备份健康数据，则需要对本地 iPhone 备份进行加密。
如果您有较旧的Mac(Mac)或 Windows PC，您可以下载 iTunes 来备份您的 iPhone 。打开 iTunes 并选择顶部的 iPhone 图标，位于Music和Library之间。
选择左侧边栏中的摘要选项卡，然后单击(Summary)手动备份(Manually Back Up)和(Back Up)还原下(Restore)的立即备份。如果要使用密码保护备份，请选择Encrypt Local Backup。
您可能还需要在某些应用程序（例如 WhatsApp）上单独备份或传输数据(back up or transfer the data separately on some apps such as WhatsApp)。检查所有包含重要数据的第三方应用程序，并确保您可以在继续之前将数据安全地移动到新手机。
你们中的一些人可能正计划切换到Android手机并完全离开Apple生态系统。在这种情况下，您可以从iPhone 上
的App Store下载(App Store)Google Drive应用程序。
打开Google Drive，然后点击左上角的三横线图标。选择Settings > Backup，然后点击开始备份(Start Backup)。备份完成后，您可以安全地继续执行本指南中的后续步骤。
注销(Deregister)iMessage 并关闭 FaceTime(Turn Off FaceTime)
如果您打算切换到Android，您应该取消注册 iMessage 并关闭iPhone 上的FaceTime。如果您不这样做，您的联系人可能会继续在这些服务上给您打电话或发短信，而您将永远不会收到他们的消息或电话。
要取消注册 iMessage，您可以在 iPhone 上打开“设置”(Settings)应用并前往“信息(Messages)” 。现在关闭 iMessage。如果您在擦除 iPhone(wipe your iPhone)之前忘记了这一步，您也可以在线注销 iMessage(deregister iMessage online)。
接下来，您可以在 iPhone 上前往Settings > FaceTime ”并关闭“ FaceTime ” 。
退出 iCloud 和 App Store
在您的 iPhone 上，您现在可以前往 Settings > [YOUR NAME]，滚动到底部，然后点击Sign Out。您可以输入您的Apple ID密码，然后轻点“关闭”(Turn Off)。这将使您退出App Store和您在此 iPhone 上的 iCloud 帐户。
擦除(Erase)iPhone 并将其恢复为出厂设置(Factory Settings)
您现在已准备好擦除 iPhone 上的所有内容。
前往Settings > General > Transfer或重置(Reset)iPhone”来执行此操作。选择擦除所有内容(Erase All Content)和设置(Settings)。您的 iPhone 会要求您输入Apple ID密码以禁用“查找我的(Find My)iPhone”。
这可确保您 iPhone 的新主人可以安全登录，而不会触发您 iPhone 的防盗功能。
如果您的 iPhone 有 eSIM，您会看到从设备中抹掉 eSIM 配置文件的选项。选择这个。您可以输入 iPhone 的密码，然后点击擦除(Erase)iPhone。这将清除所有内容并将您的 iPhone 恢复为出厂设置。
取出 SIM 卡
您应该从 iPhone 中取出SIM卡，以免意外将其交给新主人。这也将帮助您将电话号码转移到新手机上。如果您在将运营商相关服务转让给新所有者时需要帮助，您应该联系您的运营商（例如 AT&T、T-Mobile、Verizon或Sprint）。
找到盒子和充电器
现在是时候寻找 iPhone 的包装盒了，寻找包装盒随附的所有物品，例如说明书、充电线、耳机、电源适配器和Apple贴纸。如果您的 iPhone 有包装盒和所有配件，它的售价可能会更高。
以旧换新
您现在可以访问Apple Trade In、Amazon或 eBay 等网站以交易您的 iPhone。在出售您的小工具之前，请在所有这些网站上检查您的 iPhone 的转售价值。这将确保您在出售或以旧换新时获得设备的最大价值。
将数据传输到您的新设备
虽然您可以在出售 iPhone 后将数据传输到新手机，但在擦除或出售 iPhone 之前有几种方法可以这样做。在开始之前，最好将您的旧 iPhone 更新到 iOS 15 或更新版本的 iOS。转到Settings > General > Software Update并更新设备。
如果您要转移到另一部Apple手机，例如 iPhone 13，您可以打开新设备并将其靠近旧设备。
这将触发 Apple 的快速启动(Quick Start)服务，您将在旧 iPhone 上看到提示，询问您是否要将数据传输到新 iPhone。按照屏幕上的说明等待传输完成。
或者，您可以从 iCloud 备份或 Windows PC 或Mac上的本地备份进行恢复。
如果您要切换到Android手机，您可以使用兼容的适配器(compatible adapter)将您的 iPhone 连接到 Android 手机(connect your iPhone to the Android phone)。您将在Android手机上看到一个数据传输向导，您可以使用该向导将重要数据快速复制到新设备上。
从受信任的(From Trusted)设备(Devices)和Apple Pay中删除旧(Old)iPhone
最后，您可以从Apple ID上的受信任设备列表中删除旧 iPhone 。这是可以接收一次性密码以保护您的Apple帐户的设备列表。要从此列表中删除您的旧 iPhone，请在帐户页面上登录您的(account page)Apple ID。单击(Click)设备(Devices)，从列表中选择您的 iPhone，然后单击从帐户中
删除。(Remove)
您还应该访问 iCloud.com，使用您的Apple ID密码登录，然后转到“帐户设置”(Account Settings)页面。单击(Click)使用Apple Pay的设备，然后单击删除(Remove)以取消其与支付服务的链接。
享受您的新设备
恭喜，您已成功完成切换到新手机所需的一切。您现在可以查看我们的新手机相关事项(things to do with your new phone)清单。
10 Things You Should Do Before Selling Your Old iPhone
If you’re ready to sell your оld iPhone, you should take care of a few basicѕ tо enѕurе that you can seamlessly swіtch to a new device. Whether switching to a new Android phone or a new iPhone, this guide will coνer everything you should do before selling your оld iPhone.
Unpair Apple Watch and Other Bluetooth Accessories
When you’re ready to sell your old iPhone, you should start by unpairing accessories paired to your iPhone. If these are Bluetooth accessories such as the Apple AirPods, you can go to Settings > Bluetooth and tap the i button next to the accessory’s name. Then, on the next page, tap Forget This Device to unpair it.
Follow the same steps for all Bluetooth accessories paired to your Apple device.
To unpair your Apple Watch, ensure you’re wearing it, and that it’s unlocked and paired to your iPhone. Then you can open the Apple Watch app on your iPhone. Go to the My Watch tab and select All Watches. Tap the I button next to your Apple Watch and choose Unpair Apple Watch.
If you have a GPS + Cellular Apple Watch with a mobile data plan from carriers such as AT&T, you will see a prompt asking if you want to keep the cellular plan.
If you’re planning to continue using the watch or moving to a new GPS + Cellular Apple Watch, you should keep it. If not, you should remove the plan.
You may be asked to enter your Apple ID password using your iPhone at this stage. This is to disable the activation lock on the Apple Watch. When you do this, your iPhone will start backing up your Apple Watch’s data and unpair the watch.
Back Up Your iPhone
With the accessories taken care of, it’s time to back up everything on your old phone. You can use iCloud Backup to save your data on Apple’s cloud storage service. If you’re switching to another iPhone or iPad, iCloud Backup remains the easiest service to back up and restore data across Apple products.
You should first connect your iOS device to a Wi-Fi network to use iCloud. Then open the Settings app on your iPhone and navigate to [YOUR NAME] > iCloud > iCloud Backup. Select Back Up Now to start the iCloud Backup.
When the backup is complete, the progress bar will disappear, and you will see a recent timestamp below the Back Up Now button.
You should know that full device backups taken using iCloud Backup are stored on Apple servers only for 180 days. So if you’re planning to buy a new phone, such as the iPhone 13, to replace the old one, be sure to restore from the backup within six months of taking the last backup from your old iPhone.
If you want a more permanent backup, you can use your Mac or PC to take a full backup of your iPhone. If you have macOS Catalina or a new version of the operating system, connect your iPhone to your Mac using the charging cable that ships with your iPhone. Open Finder on your Mac and select the iPhone from the sidebar on the left.
Under Backups select Back Up Now to start storing all personal data from the iPhone to the Mac.
You can also choose to encrypt your backup with a password by selecting the Encrypt Local Backup option. Make sure you’ve saved this password in a password manager because you will lose access to your iPhone backup if you forget it.
Also, encrypting your local iPhone backup is necessary if you want to backup health data from your Apple Watch.
You can download iTunes to back up your iPhone if you have an older Mac or a Windows PC. Open iTunes and select the iPhone icon at the top, located between Music and Library.
Select the Summary tab in the left sidebar and click Back Up Now under Manually Back Up and Restore. If you want to protect the backup with a password, select Encrypt Local Backup.
You may also have to back up or transfer the data separately on some apps such as WhatsApp. Review all third-party apps with important data and ensure that you can safely move the data to your new phone before proceeding.
Some of you may be planning to switch to an Android phone and leave the Apple ecosystem altogether. In this case, you can download the Google Drive app from the App Store on your iPhone.
Open Google Drive and tap the three horizontal lines icon in the top-left corner. Select Settings > Backup and tap Start Backup. Once the backup is complete, you can safely proceed to the next steps in this guide.
Deregister iMessage and Turn Off FaceTime
If you’re planning to switch to Android, you should deregister iMessage and turn off FaceTime on your iPhone. If you don’t do this, your contacts may continue to call or text you on these services, and you’ll never receive their messages or calls.
To deregister iMessage, you can open the Settings app on your iPhone and go to Messages. Now turn off iMessage. If you forget this step before you wipe your iPhone, you can also deregister iMessage online.
Next, you can go to Settings > FaceTime on your iPhone and turn off FaceTime.
Sign Out of iCloud and App Store
On your iPhone, you can now go to Settings > [YOUR NAME], scroll to the bottom, and tap Sign Out. You can type your Apple ID password, and tap Turn Off. This will sign you out of the App Store and your iCloud account on this iPhone.
Erase iPhone and Restore It to Factory Settings
You’re now ready to erase all content from your iPhone.
Go to Settings > General > Transfer or Reset iPhone to do this. Select Erase All Content and Settings. Your iPhone will ask you to enter your Apple ID password to disable Find My iPhone.
This ensures that the new owner of your iPhone can safely sign in without triggering your iPhone’s anti-theft feature.
If your iPhone has eSIM, you’ll see an option to erase the eSIM profile from your device. Choose this. You can enter your iPhone’s passcode and then tap Erase iPhone. This will erase all content and restore your iPhone to factory settings.
Remove the SIM Card
You should remove the SIM card from your iPhone to avoid accidentally giving it to its new owner. This will also help you carry your phone number over to your new phone. If you need help transferring carrier-linked services to the new owner, you should contact your carrier (such as AT&T, T-Mobile, Verizon, or Sprint).
Find the Box and Charger
Now it’s time to look for your iPhone’s box and look for everything that came with the box, such as manuals, charging cables, earphones, power adapter, and the Apple sticker. Your iPhone may sell for a higher price if it has the box and all the accessories.
Trade In Your iPhone
You can now go to websites such as Apple Trade In, Amazon, or eBay to trade in your iPhone. Check the resale value of your iPhone on all of these websites before you sell your gadgets. This will ensure that you get the maximum value for your device when you sell it or trade it in.
Transfer Data to Your New Device
While you can transfer data to your new phone after selling your iPhone, there are a few ways to do so before you wipe or sell the iPhone. Before starting this, it’s best to update your old iPhone to iOS 15 or newer versions of iOS. Go to Settings > General > Software Update and update the device.
If you’re moving to another Apple phone, such as the iPhone 13, you can switch on the new device and bring it close to the old one.
This will trigger Apple’s Quick Start service, and you will see a prompt on your old iPhone, asking if you want to transfer data to the new one. Follow the on-screen instructions and wait for the transfer to complete.
Alternatively, you can restore from an iCloud backup or a local backup on your Windows PC or Mac.
If you are switching to an Android phone, you can connect your iPhone to the Android phone using a compatible adapter. You’ll see a data transfer wizard on your Android phone, which you can use to copy important data over to the new device quickly.
Remove Your Old iPhone From Trusted Devices and Apple Pay
Finally, you can remove your old iPhone from the list of trusted devices on your Apple ID. This is the list of devices that can receive one-time passwords to protect your Apple account. To remove your old iPhone from this list, log in to your Apple ID on the account page. Click Devices, select your iPhone from the list and click Remove from account.
You should also visit iCloud.com, log in using your Apple ID password, and go to the Account Settings page. Click the devices using Apple Pay and then click Remove to unlink it from the payment service.
Enjoy Your New Device
Congratulations, you’ve successfully done everything you need to do to switch to a new phone. You can now look at our checklist of things to do with your new phone.
