A phone receiving power does not prove that the cable, port, and software have established a working file-transfer connection. Charging and data are separate requirements in the same physical path.
Before replacing the phone, identify where the transfer is failing: physical connection, cable capability, device authorization, or the application’s expected transfer method.
Specify the transfer
Write down the source device, destination, and file type. A camera importing photos, a phone exposing selected folders, and a storage drive mounting as a disk are different workflows.
Read the device maker’s instructions for connection mode and authorization. Unlocking a device or approving a trusted-computer prompt may be necessary. Do not approve an unfamiliar computer merely to make a notification disappear.
Change the physical path carefully
Use a cable explicitly documented for data and connect directly to an appropriate computer port. Remove a hub temporarily. If the same cable works with a known compatible device, that is useful evidence, but not a guarantee that all devices support the same transfer workflow.
Read cable speed claims separately from wattage. USB-IF’s architecture and power documentation illustrate why the two specifications describe different aspects of a connection.
Verify the copy before deleting originals
Open transferred files at the destination and compare a small sample. For important material, keep the originals until another backup exists. A completed progress bar is not the same as verified recovery.
If the device never appears, consult its official support instructions rather than installing a random driver utility. Record the operating system, port, cable specification, and any visible error.
Our backup restore drill provides a practical verification pattern, and USB-C cable labels explain how to avoid relying on connector appearance.
