iPhone Duo Stuck on Preparing to Transfer? Here's How to Fix It

Part 1. Why Is iPhone Duo Stuck on Preparing to Transfer?

The "Preparing to Transfer" screen can stay there when Quick Start cannot establish a stable connection or needs more time to prepare your data. Common causes include:

• Wi-Fi or Bluetooth issues: Quick Start uses both connections to communicate between the two iPhones. A weak connection or network interference can interrupt the process.
• Limited storage: The new iPhone needs enough available space to receive your apps, photos, videos, and other data.
• Different iOS versions: An iOS version mismatch between the two iPhones can sometimes interfere with the transfer.
• Large data libraries: A large collection of photos, videos, apps, and other files can make the preparation stage take longer, with little visible progress on the screen.

Part 2. Basic & Native Fixes for Quick Start Stuck on Preparing to Transfer

Quick Start can get stuck because of a weak connection, network settings, or interruptions during setup. Try these native fixes first to get your iPhone Duo transfer stuck issue moving again.

1. Keep Both iPhones Close and Connected to Power

Place the old and new iPhones next to each other and connect both to wall chargers. Keep them in the same place while the transfer is running.

Avoid using either device or moving them away from each other during the transfer. A stable setup gives Quick Start the best chance to maintain the connection.

2. Turn Off VPNs and Reset Network Settings

An active VPN or incorrect network configuration can interfere with communication between the two iPhones. Turn off any VPN or third-party security service, then try Quick Start again.

If the iPhone Duo data transfer stuck again, reset the network settings on the old iPhone:

• Open Settings.
• Tap General.
• Select Transfer or Reset iPhone.
• Tap Reset.
• Choose Reset Network Settings.

• Enter your passcode and confirm.

3. Restart Both iPhones and Start Quick Start Again

Quick Start can sometimes stop responding because a background process gets stuck during setup. Restarting both iPhones gives the transfer process a fresh start. This is especially useful when the iPhone Duo transfer taking too long and there is no visible progress.

• Keep both iPhones close to each other.
• Restart both iPhones. If the screen is frozen, use the appropriate force-restart button combination for your iPhone model.
• After restarting, unlock the old iPhone and turn on Bluetooth.
• Place the two iPhones next to each other.
• Wait for the Set Up New iPhone or Quick Start prompt to appear on the old iPhone.

• Follow the on-screen instructions and enter the old iPhone's passcode when asked.
• Choose the option to transfer your data directly from the old iPhone and leave both devices close together until the process finishes.

4. Check and Match iOS Versions

Quick Start works best when the new iPhone has a compatible, up-to-date version of iOS. If the old iPhone has already been updated but the new iPhone is still running an older version, updating the new device can help when iPhone Duo transfer not working.

• Complete the new iPhone setup without transferring your data.
• Connect it to a stable Wi-Fi network and keep it plugged into power.
• Go to Settings > General > Software Update.
• If an update is available, tap Update Now or Download and Install.

• Wait for the update to finish and let the iPhone restart.
• Go to Settings > General > Transfer or Reset iPhone.
• Tap Erase All Content and Settings and follow the on-screen instructions.

• Once the iPhone returns to the setup screen, place it next to your old iPhone. Follow the Quick Start instructions and start the transfer again.

5. Clear Unnecessary Data on the Old iPhone

A large amount of temporary data, downloads, and unused files can add to the amount of data Quick Start needs to prepare for transfer. If your iPhone Duo transfer taking too long, clearing some unnecessary files from the old iPhone can help reduce the data that needs to be processed.

• Go to Settings > Apps > Safari > Clear History and Website Data. Choose the appropriate time range and confirm.

• Check the Files app and delete videos, documents, or other downloads you no longer need.
• Open the Photos app and remove large files you no longer want. Then clear them from Recently Deleted.
• Go to Settings > General > iPhone Storage and review which apps are taking up the most space. Delete apps you no longer use.
• After cleaning up unnecessary files, restart the device and try Quick Start again.
