Quick Scoop

Transferring data to a new iPhone 17 can take a long time because of large data volume, weak or unstable Wi‑Fi, outdated iOS, and device issues during setup. Public reports also show that wireless transfers can look “stuck” for hours, while a direct cable connection can reduce the estimated time a lot.

Why it slows down

  • You have a lot of data. Photos, videos, apps, and app data can make the transfer process much longer.
  • Wi‑Fi is weak or unstable. Quick Start and similar wireless transfers depend on a solid connection.
  • The old phone is busy or slow. If the old iPhone is low on storage or under strain, it can take longer to package the data for transfer.
  • The phones need a restart or a fresh setup. Some users report the process getting stuck on “Preparing to Transfer,” and restarting or switching methods helps.
  • A wireless transfer may just be slower than expected. One user reported an estimated 16 hours that dropped to 3 hours after reconnecting with a cable.

What usually helps

  1. Keep both phones plugged in and charged. Low battery can slow or interrupt the process.
  1. Use a cable if possible. Wired transfer is often faster and more stable than wireless.
  1. Make sure both iPhones are updated. Compatibility issues can slow setup.
  1. Restart both devices and try again. This can clear temporary glitches.
  1. Reduce what you transfer. If you have huge videos or lots of apps, transferring in smaller chunks can help.
  1. Check your Wi‑Fi. If the network is weak, move closer to the router or try another connection.

When it is normal

If you are moving hundreds of gigabytes , “taking forever” may still be normal, especially over Wi‑Fi. What looks frozen is often the phone processing photos, app data, and background setup steps.

If it is truly stuck

If the transfer has made no progress for many hours , or keeps failing, restarting the transfer with a wired connection is the most practical next step based on public user reports and troubleshooting guides.
