S24 5G ORIGINAL CHARGING CARD

1. Charging Port / Charging Strip Overview

The charging port (USB-C port) on the Galaxy S24 5G is the small physical interface where the charging cable connects. Sometimes, people call it the “charging card/strip” because the port is soldered on a small PCB (circuit board) inside the phone.

It consists of:

1. USB-C Connector

   • The actual plug where the cable goes in.

   • Supports:

     • Wired charging (up to 25 W fast charging).

     • Data transfer (USB 2.0/3.0 speeds depending on model).

     • OTG (On-The-Go) devices (flash drives, keyboards, etc.).

2. Charging IC / Power Management Chip

   • Regulates voltage and current.

   • Protects battery from overcharging, overheating, and short circuits.

   • Communicates with the phone’s battery to optimize charging speed (USB-PD / PPS).

3. Micro Solder Pads / Mounting PCB

   • The charging port is soldered onto a small board.

   • This PCB connects to the motherboard.

   • Sometimes called the “charging board” or “charging card.”

2. Functions of the Charging Port / Strip

1. Charging the battery

   • The primary function.

   • Converts incoming current to battery-friendly voltage.

2. Data transfer

   • Allows the phone to sync with a computer or other devices.

3. Accessory support / OTG

   • Lets you connect USB devices, external drives, mice, or keyboards.

4. Audio / Video (some USB-C functions)

   • Supports digital audio output and sometimes video output via USB-C Alt Mode.

3. Reasons for Replacement

The charging port or strip may need replacement if any of the following happens:

1. Physical damage

   • Bent or broken pins inside the port.

   • Port gets loose and doesn’t hold the cable.

2. Water or liquid damage

   • Corrosion or short-circuits caused by moisture.

3. Wear and tear

   • Frequent plugging/unplugging can loosen connectors.

4. Charging issues

   • Phone stops charging or charges intermittently.

   • Overheating at the port.

5. Data transfer issues

   • PC or accessories no longer detect the phone.

6. Power management failures

   • Internal PCB or IC can fail, preventing charging or communication with the battery.

4. Maintenance Tips

• Use good quality USB-C cables.

• Avoid forcing the plug in the wrong orientation.

• Keep the port clean and dry; use a soft brush to remove dust.

• If replacing, use original or OEM parts for proper compatibility.
