S21 PLUS 5G ORIGINAL CHARGING CARD

🔌 Key Specifications of the Charging Port

• The S21 Plus uses a USB Type‑C port (USB‑C) for wired charging and data transfer.

• It supports USB 3.2 speeds and USB On‑The‑Go (OTG) capability via that port.

• Wired fast charging capability: up to 25 W. It uses USB Power Delivery 3.0 standard via the port.

• Wireless (Qi/PMA) and reverse wireless charging are also supported, but those go through coils in the phone, not the port itself.

• The port is integrated into a small bottom board or daughterboard assembly in many phones (for these Samsung models) rather than just a loose standalone connector. In repair forums users refer to it as the “bottom board / charging board / USB‑C board”.

🛠 What the Original Port Assembly Includes

When purchasing a genuine replacement or verifying authenticity, you’ll often find these features:

• The USB‑C female connector (reversible type) mounted on a small PCB daughterboard.

• One or more microphones may share the same board (common in Samsung phones).

• The board will have flex cables or ribbon connectors to main board.

• Markings indicating the version/model (e.g., to match region/model variant such as SM‑G996B/DS). The correct part number is important.

• Often the board will include shielding, screw posts, and/or glue tabs to fit correctly in the phone chassis.

✅ How to Confirm It’s “Original / Genuine”

• Ensure the model number on your phone (found under Settings → About Phone) is matched with the part you buy (for example SM‑G996B international version). Wrong variant parts may lead to signal or function issues.

• Check for manufacturer/certification markings on the board (Samsung logo, revision number, serial).

• Look for proper alignment of the port: the USB‑C opening should line up flush with the bottom frame of the phone and feel securely fixed.

• The board should include all features you expect: for example if your phone had dual SIM or specific microphone placements, ensure the daughterboard reflects that.

• Ask for high‑quality photos and/or compare with known originals (repair forums often show differences between cheap generic replacements vs genuine).

• Read reviews/feedback: some forums report issues when generic ports cause charging to stop, or wireless charging to fail.

⚠️ Common Issues & Maintenance Tips

• Lint / debris in port: Many charging issues (intermittent charging, slow charging, no recognition) stem from debris. One Reddit user wrote:

  “I cleaned the port out even more … I can charge my phone wired now.” 
  So regularly inspect the port and gently clean (with phone off!) using a non‑metal, soft tool (toothpick, compressed air) if needed.

• Loose connector or flex damage: Over time, repeated plugging/unplugging can loosen the port or damage flex cables. In repair threads one recommended replacing the charging board.

• Wrong part variant: Using a part meant for a different region may cause signal issues (SIM or network) or not support fast charging properly.

• Cable/charger mismatch: Even with the good port, using a weak or underspecified charger/cable may prevent reaching fast‑charge speeds. One user wrote they stopped getting “Super Fast Charging” even though hardware looked fine.

• Water/dust ingress: The phone has an IP68 rating, but the port area still can be vulnerable. Moisture or oxidation at connector pins can degrade performance.

📋 What to Ask or Check Before Buying Replacement Port in Karachi / Pakistan

• Verify phone model number (international vs carrier variant).

• Ask for photos of the port board: connector pins, board markings, flex cables.

• Prefer sellers who state “OEM / original” and give warranty (even short) for part.

• Confirm ports support USB‑C 3.2 / OTG / PD3.0 (if you care about fast charging and data transfer).

• If you’re handling replacement yourself (or with a technician), ensure you use proper tools (anti‑static environment, correct screwdrivers, heat gun if needed for adhesive) and handle easily‑broken flex cables carefully.
