Replacement charging board on S23 Ultra only briefly charges?

Understanding Charging Issues After Replacing the Charging Board on Samsung Galaxy S23 Ultra

If you’ve recently replaced the charging port and internal charging board on your Samsung Galaxy S23 Ultra and are experiencing intermittent charging issues, you’re not alone. Many users encounter similar problems after performing hardware repairs, which can be both frustrating and perplexing. This article aims to provide insights into possible causes and troubleshooting steps to help resolve such charging behavior.

Identifying the Issue

In this scenario, you’ve replaced the charging port and battery assembly due to a loose port and rapid battery drain. Post-repair, the device’s battery appears to function normally. However, when connecting the charger, the device begins charging briefly—typically for one to two minutes—before the charging process halts without any external interaction. Reconnecting the charger resumes charging, only to stop again shortly after, leading to inconsistent power delivery. Notably, wireless charging continues to work without issue.

Potential Causes and Troubleshooting

Compatibility and Quality of Replacement Parts
Third-Party Components: If the replacement charging board isn’t an official Samsung part, variations in quality or manufacturing standards could affect performance. Lower-quality components might have imperfect circuitry or connectors, resulting in unstable charging behavior.
Solution: Consider sourcing genuine or OEM replacement parts to ensure compatibility and reliability.
Internal Connection Checks
Secure Fittings: Double-check all internal connections, including cables, connectors, and screws, to ensure they are firmly and correctly seated.
Inspection: Look for any signs of damage or corrosion on connectors and nearby components that could hinder stable power flow.
Firmware and Software Considerations
Calibration and Updates: Sometimes, hardware changes require software adjustments. Ensure your device’s firmware is up-to-date, as updates can improve hardware compatibility and performance.
Solution: Perform a software update via official channels or consider performing a factory reset after backing up essential data.
Potential Defects in the Replacement Board
If the part is a non-OEM component, manufacturing errors or defects could cause intermittent charging.
Solution: Test with a different, verified replacement part if available.
Electrical and Power Management Circuitry
The charging process involves complex circuitry, including power management ICs. A faulty replacement part or improper installation could disrupt these circuits.
Solution: Ensure correct installation and consider consulting a professional technician for thorough hardware diagnostics.
