Steps
Power the phone off and remove the back cover. Disconnect the battery connector before you touch anything else, then take out the screws and shields over the charging board.
Plug a USB amp meter into the port to confirm the fault is the connector and not the cable, charger or battery. A port that draws nothing or cuts in and out points to the connector.
Lift the charging board or motherboard out of the frame and tape it flat on your work surface. Set it under the microscope so the Type-C pins are centred in view.
Brush flux over the connector's anchor tabs and pins. Heat them with the hot air station at about 350 to 380 degrees Celsius, moving the nozzle, until the solder flows.
Lift the old connector off with tweezers while the solder is still molten. Never pull on it cold or you will tear pads off the board.
Clean the pads with solder wick and a little flux, then wipe with isopropyl alcohol. Check under the microscope for lifted or bridged pads before going further.
Tin the pads and the new connector's pins with a thin layer of solder. Line the connector up on its outline marks and tack two opposite corners first.
Solder the remaining pins and anchor tabs with the fine iron or short hot air passes. Add flux as needed and keep the heat brief so the plastic housing does not melt.
Check every pin for bridges with the multimeter in continuity mode, then look over the joints under the microscope. Reflow anything that looks dull or lumpy.
Refit the board, reconnect the battery, and test charging and data transfer with the amp meter. Close the phone only once charging is stable.
Tips and common mistakes
Practise the removal and refit on a scrap Samsung board before you work on a phone you need.
Keep the hot air nozzle moving and never hold it still on one spot, or you will scorch the board and nearby plastic.
Work in a ventilated room and wear safety glasses, since flux fumes and solder splatter are common at these temperatures.
If the phone still will not charge after the swap, test the cable and charging brick before blaming your solder joints.
Questions
Can I do this with a normal soldering iron only?
It is very difficult. The Type-C connector has anchor tabs that need hot air or a strong iron to release, and a basic iron often lifts pads. A hot air rework station is the practical choice.
Do I need a microscope?
Not strictly, but the pins are tiny and closely spaced. A digital microscope or a strong loupe makes it much easier to spot bridges and lifted pads.
Will a new port fix a phone that charges slowly?
Only if the port itself is worn or damaged. Slow charging is often the cable, the charger or the battery, so test those first with a USB amp meter.
