Charging port is one of the most vulnerable parts in a smartphone. The charging port is easily to loosen after being plugged in and out or getting stuck by dusts or rust. A broken charging port will certainly influence the charging speed as well as the charging result. To replace a charging port only costs less, but requires more complicated skills than replace a charging port with PCB board. Here we walk you through how to replace a Samsung Galaxy phone or an iPhone charging port.
Tools Needed:
Heat Gun
Soldering Tin
Soldering Paste
Toothpicks

(Take Galaxy S3 as an example.)
Step 1: Get some soldering paste with the help of a toothpick, gently apply it around the welding areas of a charging port.
Step 2: Heat uniformly on the welding areas.
Generally, the charger port is built into a PCB board (aka a daughter board), which should be heated at about 280 ~ 300 centi-degree in the first minute, 320 centi-degree will be fine afterwards.
As for the charging port being built into a flex ribbon (i.e. Galaxy Tab S 10.5 charging port with flex), the heating temperature should be turned down to 280 centi-degree from beginning to end so as to protect the fragile flex cable ribbon from burnt.
Step 3: Gently remove the charger port with the help of a tweezers.
Step 4: Apply some soldering tin around the welding areas of the daughter board evenly, then apply the soldering paste in the same path.
Step 5: Gently put the replacement USB charger port in the soldering areas, slightly adjust the charging port to the right place, fix it with a tweezers while heat it at the same time.

(Take iPhone 5 as an example.)
Step 1: Heat up around the charging port welding areas uniformly.
Step 2: Gently remove the charging port by a tweezers.
Step 3: Apply some soldering tin around the welding areas of the daughter board evenly, then apply the soldering paste in the same path.
Step 4: Gently put the replacement USB charger port in the soldering areas, slightly adjust the charging port to the right place, fix it with a tweezers while heat it at the same time.
