INFINIX HOT 50i X6531B Charging Problem Solution

In this video, you will learn how to fix INFINIX HOT 50i X6531B charging problem. If your phone is not charging, charging slowly, or shows no charging icon, this complete hardware repair guide will show you how to troubleshoot and fix issues with the charging port, sub-board, charging IC, battery connector, and voltage lines step by step. 🔧 30-Step Charging Problem Repair Guide: Power off the Infinix HOT 50i X6531B completely. Remove the SIM tray and open the back cover using a heat gun. Disconnect the battery to ensure safe repair. Remove the screws and take out the charging sub-board. Inspect the USB charging port for physical damage or dirt. Clean the port using isopropyl alcohol and a soft brush. Test the USB port's continuity using a multimeter. If the port is loose or broken, desolder and replace it. Check the VBUS and GND lines for continuity. Inspect the charging sub-board for burnt or missing components. Test the fuse and diode near the charging connector. Replace any open fuse or shorted diode. Check for corrosion or broken tracks on the sub-board. Test the battery connector pins for voltage output. Replace damaged battery connectors. Test the output from the charging port to the mainboard. Use schematic to trace charging lines to the PMIC. Test the charging path from the sub-board to the mainboard. Inspect and test SMD components along the charging line. Reflow the charging IC or replace it if there's no output. Measure battery charging voltage while plugged in (should be ~4.2V). Test for current draw using USB ammeter (should be 0.5A to 2A). Replace the charging flex cable if found faulty. Flash the stock firmware if charging works only intermittently. Use a different original charger and cable for testing. Ensure the battery itself is not faulty or swollen. Replace the battery if voltage is not holding above 3.7V. Reassemble the phone and secure all screws. Power on and confirm that the phone charges properly. Deliver the fully tested and repaired phone to the customer. 🔍 Hashtags: #InfinixHot50iChargingFix #ChargingProblemSolution #InfinixRepairGuide #MobileChargingIssue #USBPortRepair #InfinixX6531BCharging #NotChargingFix #InfinixHardwareSolution #SlowChargingFix #ChargingICRepair
