Start by matching the ports on both phones:

• USB-C to USB-C: Common on many newer phones for a direct wired transfer.
• USB-C to Lightning: Useful when one phone has USB-C and the other uses Lightning.
• USB-A to USB-C/Lightning with an OTG adapter: Helpful if one device needs a host (OTG) connection.

Look for cables labeled data transfer (not just charging) and check the speed rating (e.g., 480 Mbps, 5 Gbps, 10 Gbps). Some models may require a small adapter. It’s a good idea to confirm in your phone’s setup guide which wired options are supported, since compatibility can vary by device and software version.

1. Charge and update both phones so they stay powered and current.
2. Use a data-capable cable that fits both ports (or a compatible adapter/OTG plug).
3. On the new phone, start setup and choose a wired/cable transfer option if available.
4. Unlock the old phone and approve any prompts (file transfer/allow data).
5. Select what you’d like to copy (photos, videos, contacts, messages, and more).
6. Keep devices connected and awake until the process completes.

Exact steps vary by brand and OS, but this flow generally works. If a direct cable option isn’t offered, a local backup or cloud restore can supplement content that doesn’t transfer over cable.

Wired transfers can copy a lot, but “everything” depends on the phones involved. Here’s a balanced approach:

• Use the new phone’s setup tool and a data-capable cable to move core items (photos, videos, contacts, messages, and some apps/settings).
• Sign into your accounts (email, app stores, messaging) to restore app data that isn’t moved by cable.
• Re-download apps that don’t carry over automatically.
• Check special items like secure notes, authenticator codes, and downloads; these may need manual steps.

When finished, compare both phones and only reset or trade in the old one after you’ve verified everything you need is present.

Not all charging cables can transfer files. Key differences include:

• Wiring: Data cables include data lines for file transfer; some charge-only cables omit these.
• Speed rating: Labels like USB 2.0 (up to 480 Mbps) vs. USB 3.x (up to 5–10 Gbps) indicate potential transfer performance.
• Specs/packaging: Look for terms such as “data transfer,” “USB 3.x,” or a Gbps rating in the description.
• Connectors and chips: Some USB-C cables include e-marker chips for power; data speed still depends on the cable’s USB version.

Checking the product specs is the most reliable way to confirm data support and expected speed.

Look for clear specs in the description:

• USB version: USB 3.0/3.1/3.2 typically offers 5–10 Gbps; USB 2.0 is up to 480 Mbps.
• Stated speed: Terms like 5 Gbps or 10 Gbps indicate faster data capabilities.
• Connector type match: Ensure the cable fits both devices (USB-C, Lightning, etc.) and both devices support higher speeds.
• Length and build: Shorter, well-shielded cables can provide more reliable high-speed transfers.

Actual performance depends on the slowest link (device port, cable rating, or adapter). If any part of the chain is USB 2.0, transfers will be limited to that speed.
