Overview
The Samsung Galaxy S23 Ultra uses a USB-C port that supports 45W Super Fast Charging 2.0, but this port is susceptible to lint compaction and connector wear over time. When the S23 Ultra stops charging or only trickle charges, the problem is most often a dirty port, a degraded cable, or a failing battery — though charging IC faults on the motherboard are also possible.
Common Causes
- Lint and debris compacted in the USB-C port blocking full connector insertion
- Damaged or non-Samsung charging cable unable to negotiate 45W fast charging
- Battery health degraded below the threshold for accepting Super Fast Charging
- Charging IC or power management fault on the S23 Ultra motherboard
- Moisture in the USB-C port triggering the liquid detection alert and blocking charging
Signs & Symptoms
- S23 Ultra shows no charging animation when cable is connected
- Device charges at 5W instead of the expected 45W Super Fast Charging rate
- Liquid detection warning appears even when the phone and cable are dry
- Charging cable feels loose or requires precise positioning to make contact
Should You Try DIY?
Never use sharp metal tools to clean a USB-C port as this can damage the internal contacts. The S23 Ultra motherboard charging circuits require specialist equipment to diagnose and repair — do not attempt motherboard-level repairs at home.
