Oppo A5 / A9 2020 Fake Charging FIXED! (Short on DP/DN Line)

Struggling with your Oppo A5 or A9 (2020) showing "Charging" but the battery percentage doesn't increase? You're not alone! This is a very common issue known as "Fake Charging." In this detailed repair guide, I walk you through the step-by-step process of diagnosing and fixing this problem on the Oppo A5/A9 2020 motherboard. The root cause was a short circuit on the DN (Data Negative) line of the USB charging port circuit. 🔧 What Was The Problem? The phone would show a charging symbol but would not actually charge the battery.Using a thermal camera and a multimeter, we traced the short to a failed protection diode near the USB port controller. The DP (Data Positive) line was okay, but the DN line was shorted to ground. ✅ The Solution: We successfully removed the faulty protection diode,which eliminated the short circuit entirely. After this micro-soldering repair, the phone began charging perfectly and normally. ⚠️ Important Disclaimer: This is an advanced hardware-level repair.It requires expertise in micro-soldering, the right tools (microscope, soldering station, flux), and a good understanding of motherboard circuitry. If you are not confident, please take your device to a professional repair technician.
