Way 1. Quick Start — Best for Direct iPhone-to-iPhone Transfer
Quick Start is the easiest option when your old iPhone is still available. It transfers your iPhone photos, settings, apps, messages, and other data directly to the new iPhone Duo/18 Pro/Pro Max, so you can continue using the new device with little manual setup.
How to Transfer Data from Old iPhone to iPhone with Quick Start
Step 1. Turn on your new iPhone Duo/18 Pro/Pro Max and place it close to your old iPhone. The old device should show the "Set Up New iPhone" prompt automatically.
Step 2. Tap Continue on the old iPhone, then use its camera to scan the blue animated pattern displayed on the new iPhone.
Step 3. Enter your old iPhone's passcode on the new device and follow the prompts to set up Face ID.
Step 4. When asked how you want to transfer your data, choose "Transfer from iPhone". Keep both iPhones close together and connected to power until the transfer finishes.
The transfer time varies with the amount of data stored on the old iPhone. Large photo libraries, videos, and app data can make the process take considerably longer, so avoid using or moving either device during the transfer.
Way 2. Temporary iCloud Backup — Best for Wireless Transfer
Temporary iCloud Backup is useful when you prefer a wireless setup or need to hand over the old iPhone soon for an Apple Trade-In or sale. Apple provides temporary iCloud storage for the transfer, so you don't have to upgrade your regular iCloud storage just for this move.
How to Transfer Data to New iPhone with Temporary iCloud Backup
Step 1. On your old iPhone, open Settings > General > Transfer or Reset iPhone, then tap Get Started under the "Prepare for New iPhone" section.
Step 2. Follow the onscreen instructions to create a temporary iCloud backup. Apple provides additional temporary iCloud storage for this transfer, and the backup remains available for a limited period.
Step 3. Turn on your new iPhone and start the setup process. Sign in with the same Apple Account used on your old iPhone.
Step 4. At the Apps & Data screen, select "Restore from iCloud Backup", then choose the temporary backup you just created. Keep the new iPhone connected to Wi-Fi and power while the data is restored.
Way 3. Mac/PC Local Backup — Best for Large Data Transfers
A local computer backup makes more sense when the old iPhone contains hundreds of gigabytes of photos, videos, and app data, or when the available Wi-Fi connection is unreliable. An encrypted local backup also preserves additional information that a standard computer backup does not include.
How to Back Up an Old iPhone and Restore It to New iPhone
Step 1. Connect your old iPhone to a Mac with a USB cable. Open Finder and select the iPhone from the sidebar. On Windows, open the Apple Devices app or iTunes, depending on your setup.
Step 2. Choose the option to back up the iPhone to this computer, then turn on "Encrypt local backup." Set a backup password when prompted and keep it somewhere safe. An encrypted backup can include saved passwords, Wi-Fi settings, Health data, and other sensitive information that isn't included in an unencrypted backup.
Step 3. Start the backup and wait until the process is complete. For a large iPhone library, this can take some time, so keep the phone connected throughout the process.
Step 4. Turn on the new iPhone and connect it to the same Mac or PC with a USB-C cable. During setup, choose the option to restore from a computer backup, then select the encrypted backup and enter its password.
Way 4. WinX MediaTrans — Best for Selective iPhone Data Transfer
Quick Start, iCloud, and Finder or iTunes are convenient for moving an entire iPhone to a new device, but they leave less room for selective transfers. WinX MediaTrans takes a different approach, letting you move specific photos, videos, music, books, and other files between an iPhone and a Windows PC without relying on iCloud storage or iTunes.
Selective transfer. Instead of copying everything from the old iPhone, you can choose the files and categories worth moving to your iPhone 18. This is useful for a large photo library or when the new phone doesn't need every old app file and media item.
No iTunes or iCloud limits. MediaTrans works through a direct computer connection, so the transfer does not depend on iCloud storage capacity or require iTunes for basic file management. Large local collections can be stored on the PC first and transferred back to the new iPhone as needed.
Hardware-accelerated conversion. MediaTrans can convert incompatible media during transfer, helping prepare files for playback on the new iPhone. Its hardware acceleration can also reduce the time needed to process large batches of photos and videos.
Music and ringtone tools. MediaTrans can transfer music that wasn't purchased through iTunes and create iPhone ringtones from your own audio files. It also supports transferring eBooks and other personal content, giving you more control over files that don't fit neatly into Apple's standard migration process.
Step 1. Install and launch WinX MediaTrans on your computer, then connect your old iPhone to the computer with a USB cable. Download the Windows version or Mac version and follow the onscreen instructions to complete the setup.
Step 2. Click Photo Transfer on the main interface and select the photos or other files you want to move to your new iPhone Duo/18 Pro/Pro Max. Click Export at the top left to copy the selected files from your old iPhone to the computer. The same method can be used to back up other supported content before transferring it to the new device.
Step 3. Disconnect the old iPhone and connect your new iPhone Duo/18 Pro/Pro Max to the computer. Open Photo Transfer, create a new album with the + button when needed, then click Add Photo to select the files saved from your old iPhone. Click Sync at the bottom right to transfer the selected photos to your new iPhone.
iPhone Duo/18 Pro/Pro Max Transfer Troubleshooting: 6 Common Pitfalls
Apple's built-in transfer tools handle most of the heavy lifting, but some apps and services follow their own rules. These are the main issues worth checking before erasing your old iPhone.
1. Older iOS or Beta Version Blocks the Transfer
A backup made on a newer iOS version cannot normally be restored to an iPhone running an older release. A message such as "Backup is from a newer version of iOS" can appear during setup.
Fix: Set up the new iPhone temporarily without restoring the backup, update iOS under Settings > General > Software Update, then erase the new device and start Quick Start or backup recovery again.
2. WhatsApp, Signal, and Other Apps May Need Their Own Transfer Steps
Moving an app to the new iPhone does not always move its account data or login session. Before starting the migration, check the backup or transfer option inside apps such as WhatsApp, Signal, LINE, Slack, and Microsoft Teams. Enterprise apps may also require a fresh SSO or 2FA sign-in.
Fix: Back up WhatsApp chats from WhatsApp > Settings > Chats > Chat Backup before switching phones. Signal uses its own transfer process rather than an iCloud backup. Keep the old phone available until messaging, work accounts, and important app data have been verified on the new one.
3. eSIM May Not Activate Along with the Rest of Your Data
Contacts, photos, and settings can arrive on the new iPhone while cellular service is still waiting for activation. This is especially important for users relying on carriers such as AT&T, T-Mobile, Verizon, or Vodafone.
Fix: Accept "Transfer Cellular Plan" during setup when the option appears. A failed transfer may require the carrier's app, activation process, or an eSIM QR code. Make a test call and confirm SMS and mobile data work before wiping the old iPhone.
4. Don't Erase the Old iPhone Before Checking 2FA and Banking Apps
Banking apps and authenticator apps often have additional security checks that aren't handled by a standard device migration. Google Authenticator, Microsoft Authenticator, Duo, password managers, and financial apps may require account recovery, re-verification, or device approval.
Fix: Transfer authenticator accounts using the app's own migration or backup feature, then open your important banking and security apps on the new iPhone. Test 2FA codes and sign-in before removing the old device from your accounts.
5. Quick Start Gets Stuck or Takes Too Long
Large photo libraries and unstable wireless connections can make Quick Start appear stuck at "Preparing to Transfer" or show a very long remaining time.
Fix: Keep both iPhones charged, close together, and connected to a stable connection. Repeating the transfer may help, while a direct wired connection is worth considering for a particularly large migration.
6. Missing Photos or Apps May Still Be Syncing
The new iPhone can reach the Home Screen before every photo, app, or iCloud Drive file is fully available. Large libraries may continue downloading in the background, so an incomplete-looking library does not necessarily mean data has been lost.
Fix: Keep the new iPhone connected to Wi-Fi and power and give the background sync time to finish. Check Settings > [Your Name] > iCloud and verify the important photos, files, and apps before deciding that anything needs to be transferred again.
FAQs About Transferring Data to a New iPhone
1. Why is Quick Start stuck on "Preparing to Transfer" or "Estimating Time Remaining"?
Large photo libraries, unstable connections, device heat, or a temporary Quick Start error can slow or interrupt the process. Keep both iPhones near each other and powered on. For persistent failures, restart both devices and try again or use a wired transfer.
2. Why are some apps missing or still showing "Loading" after transferring to a new iPhone?
Quick Start can finish the main setup before every app has been downloaded from the App Store. Keep the new iPhone connected to Wi-Fi and power, then allow the remaining apps and content to finish downloading.
3. Will WhatsApp chats transfer automatically to my new iPhone?
WhatsApp has its own chat backup and transfer process, so don't assume every conversation will be ready immediately after Quick Start. Keep the old iPhone intact and verify your chats, photos, and recent messages before erasing it.
4. Why did my eSIM transfer but show "No Service" on the new iPhone?
eSIM transfer depends on carrier support and activation. A successful data migration does not guarantee cellular service is ready. Check Settings > Cellular, complete any carrier prompts, and confirm calls, SMS, and mobile data before removing the old device.
5. Can I transfer data when the new iPhone has an older iOS version?
A backup created on a newer iOS release may not restore to an older version. Update the new iPhone before restoring it. When setup prevents the update, complete setup without the transfer, update iOS, erase the device, and restart migration.
6. Should I erase my old iPhone immediately after the transfer finishes?
No. Keep the old iPhone until you have checked photos, messages, contacts, WhatsApp, authenticator apps, banking apps, eSIM service, and important files. Some content may still be downloading or require separate account verification after the initial migration.
7. Why did Quick Start finish but some recent WhatsApp messages disappear?
WhatsApp chat history follows its own backup or direct-transfer process and may not match the timing of the broader iPhone migration. Verify the latest conversations on the old phone and complete WhatsApp's transfer or restore process before deleting anything.
8. What should I do when Quick Start keeps returning to the "Set Up New iPhone" screen?
Restart both iPhones and make sure Bluetooth and Wi-Fi are enabled. Update the devices when possible, then try Quick Start again. If direct transfer continues to fail, restore from an iCloud or encrypted computer backup instead.
