Samsung S21 Ultra 5G Charging Port: Technical Specifications of the Samsung S21 Ultra 5G

The Samsung S21 Ultra 5G is equipped with a USB Type-C port. This modern standard offers several advantages:

  • USB Version: USB 3.2, ensuring high data transfer speeds.
  • Fast Charging: Supports USB Power Delivery (PD) 3.0, enabling super-fast charging up to 25W with the appropriate charger.
  • OTG (On-The-Go): Allows direct connection of other USB devices to the phone, such as USB drives, keyboards, or mice (with an adapter if needed).
  • Video Output: Can transmit video signals, for example, to connect the phone to a compatible monitor or TV (requires a USB-C to HDMI/DisplayPort cable or adapter).
  • Reversible Design: No need to worry about orientation when plugging in the cable.

It is important to note that the "charging port" as a replacement part for the Samsung S21 Ultra 5G is generally not just the metallic USB-C connector. It is a module or secondary board (daughterboard) that includes the USB-C port, the main microphone, and sometimes other components like FPC connectors for the mainboard or the SIM reader, depending on the exact revision of the part.

Compatible Charging Port References for Samsung S21 Ultra 5G

When searching for a replacement charging port for your S21 Ultra 5G, it is crucial to find the correct reference. The most common are:

  • GH96-14064A: Generally associated with model SM-G998U (U.S. version).
  • GH96-14201A: Generally associated with model SM-G998B (International/European version).

It is essential to verify the exact compatibility with your specific S21 Ultra 5G model before purchasing the part. At iLevante.com, we guide you to find the perfect Samsung S21 Ultra 5G charging connector replacement.

How Often Should the Charging Port Be Replaced?

There is no fixed interval for replacing the charging port. Its lifespan depends on several factors:

  • Frequency of use: The more you connect and disconnect the cable, the greater the physical wear.
  • Care when connecting: Forcing the cable, connecting it at incorrect angles, or using poor-quality cables can damage the internal pins.

Estimated Battery Life: Intensive vs. Light Use

The battery life of the S21 Ultra 5G is highly variable and depends significantly on the device's configuration (screen brightness, adaptive vs. fixed refresh rate), network coverage, active applications, and overall battery health.

  • Light Use: (Occasional web browsing, social media, messaging, some music). It could last more than a full day, exceeding 8-10 hours of screen-on time under optimal conditions.
  • Moderate/Mixed Use: (Combination of browsing, social media, video, music, some camera use). It is generally expected to last a full day, with about 6-8 hours of screen-on time.
  • Intensive Use: (Demanding 3D gaming, extended 4K/8K video recording, intensive GPS and mobile data use with the screen at maximum brightness). The duration may significantly reduce, possibly to 3.5-5 hours of screen-on time.

Note: These are estimates. Over time and with charge cycles, the battery's maximum capacity degrades, reducing these times.

When to Replace Your S21 Ultra's Battery?

Consider replacing your Samsung S21 Ultra 5G battery if you notice:

  • A drastic decrease in duration with the same usage pattern.
  • Unexpected shutdowns, even if the battery indicator shows charge.
  • The phone only works if connected to the charger.
  • The battery drains very quickly.
  • Physical swelling of the battery (this is dangerous and requires immediate attention).
  • The Samsung Members app (or similar) indicates that the battery's health is poor or needs replacement.

Diagnosis: Is it the Charging Port or the Battery? ?

Before rushing to buy spare parts, it is crucial to diagnose the problem correctly. A faulty Samsung S21 Ultra 5G charging port can exhibit symptoms similar to a depleted battery.

Common Symptoms of a Faulty Charging Port

  • The phone does not charge or the charging is intermittent (connects and disconnects).
  • Super Fast Charging does not activate, and it only charges slowly.
  • The USB cable has excessive slack in the port or disconnects easily.
  • You have to move or angle the cable for it to start charging.
  • The computer does not recognize the phone when connected via USB (data transfer issues).
  • There is visible physical damage inside the port (bent, broken, or corroded pins).
  • Moisture detected warnings even though the phone has not been wet recently (may indicate corrosion).

Steps to Diagnose Charging Issues

  1. Visual Inspection: With good lighting, inspect the inside of the USB-C port for lint, dirt, or damaged pins.
  2. Careful Cleaning: If you see dirt, try cleaning it with compressed air (short bursts) or a fine non-metallic tool (like a plastic or wooden toothpick), being very careful not to damage the pins. Never use metal objects!
  3. Test with Another Cable and Charger: Use an original Samsung USB-C cable and charger or a high-quality one that you know works properly with other devices. This rules out issues with the cable or power adapter.
  4. Try Wireless Charging: The S21 Ultra 5G supports Qi wireless charging. If the phone charges perfectly wirelessly but not via cable, the issue likely lies in the USB-C port.
  5. Restart the Phone: A simple restart can sometimes fix minor software glitches that could affect charging.
  6. Safe Mode: Boot the phone in Safe Mode to see if any third-party application is interfering. If it charges well in Safe Mode, the issue could be an app.
  7. Diagnosis with Samsung Members: The Samsung Members app has diagnostic tools that can help you check the battery status and cable charging connection.

Differentiating Charging Port Issues vs. Battery Issues

  • If wireless charging works but cable charging does not, the port is the main suspect.
  • If there are data transfer issues with the PC, it is almost certainly a port issue.
  • If the phone drains very quickly but charges normally (both via cable and wirelessly when it does), the battery is the most likely candidate for replacement.
  • If no charging method works and you've tested different cables/chargers, the issue could be more severe (battery, motherboard, or the port module itself).

Step-by-Step Guide: How to Replace the Charging Port of the Samsung S21 Ultra 5G

If you've confirmed that the charging port is the culprit and feel confident and skilled enough to perform a hardware repair, here is a general guide. This repair is of moderate to high difficulty.

Precautions and Common Issues When Repairing the Charging Port ??

Even with a guide, problems can arise. Here are some common ones and how to prevent them:

List of Possible Complications

  • Damaging the glass back cover: It is very fragile. Apply heat evenly and do not use excessive force when prying.
  • Breaking flex cables: They are extremely delicate. Always use plastic tools to disconnect them and pull gently and perpendicularly to the connector. Never pull the cable itself.
  • Losing or mixing screws: They are tiny and often of different lengths. Organize them well. Using the wrong screw can damage the motherboard or screen.
  • Failing to reconnect the battery properly: This may result in the phone not powering on or having power issues.
  • Damaging the battery: Avoid puncturing or bending it. A damaged lithium battery can catch fire.
  • Forgetting a connector: This will result in some function not working (microphone, speaker, signal, etc.).
  • Poorly applied adhesive: The back cover may come loose or completely lose its (already compromised) water resistance.
  • Static damage (ESD): Use an anti-static wrist strap and work on an appropriate surface to protect sensitive electronic components.

Tips to Prevent Common Errors

  • Take your time: Rushing is the worst enemy in these repairs.
  • Document the process: Take pictures as you disassemble to remember where each piece and screw goes.
  • Work in a clean and organized environment.
  • If something doesn?t fit, don?t force it: Check for obstructions or if you are using the wrong part/screw.
  • Consult multiple guides: Watching specific repair videos for the S21 Ultra 5G can be very helpful.
