USB cable data troubleshooting

iPhone Charges from PC but Cannot Transfer Photos

Charging proves only that power reaches the phone. Some cables and adapters cannot carry stable data.

Understand the problem

For this specific problem, start by separating the condition of the original files from the method used to transfer them. Charging proves only that power reaches the phone. Some cables and adapters cannot carry stable data. A few controlled test files will tell you more than restarting an entire library copy.

What to do, in order

  1. Replace the cable with one specifically documented to support data transfer.
  2. Try a direct PC port rather than a monitor hub, keyboard hub or dock.
  3. Unlock the iPhone and allow the computer trust request if shown.
  4. Start with a tiny import in Windows Photos before attempting an entire library.

Mistakes to avoid

  • Do not assume all USB-C cables have equal data capabilities.
  • A low-quality or loose connector may work for charging yet disconnect during large videos.

Verify before changing or deleting source files

Copy a photo and a short video. If both finish without interruption, gradually test a larger batch to distinguish detection from transfer instability. If a batch contains irreplaceable family or work photos, keep a second independent copy before clearing the iPhone. Do not rely only on a progress indicator or a preview thumbnail.

When wireless DropToPC helps

If the cable continues to be unreliable, DropToPC transfers selected photos and videos wirelessly. It offers free direct LAN transfer at original quality. The official DropToPC website provides the iPhone and Windows apps and its current transfer guide. Free transfers preserve the original photo and video quality; local-network transfers are free without cumulative traffic or usage limits. Free cross-network transfer runs at a speed below Pro, while Pro provides a higher-speed mode and cross-network automatic backup.

For other methods, see our iPhone-to-Windows transfer comparison and tool directory. The correct method still depends on whether the full original is accessible and on the destination’s available storage.

Want a dedicated wireless transfer from iPhone to Windows?

DropToPC uses QR-code pairing and supports Windows 10 and 11. Free transfers preserve original photo and video quality. On a local network, transfers are direct, fast and free with no cumulative volume or usage caps. Across different networks, the free tier still has no cumulative volume or usage cap, but operates at a lower speed than Pro. Pro also adds cross-network automatic backup.
