@punjabmobilerepairing: Mobile Phone Charging Lines (Pins) – Names & Work Most modern phones use USB charging ports like USB Type‑C or Micro‑USB. These ports usually have 5 main lines. 1️⃣ VBUS (Power Line) ⚡ Function: Supplies power from the charger to the phone. 📌 Use: Charges the battery. 2️⃣ GND (Ground Line) 🔋 Function: Completes the electrical circuit. 📌 Use: Helps electricity flow safely. 3️⃣ D+ (Data Positive Line) 💾 Function: Transfers data between phone and computer. 📌 Use: File transfer, USB connection. 4️⃣ D− (Data Negative Line) 💾 Function: Works with D+ for data communication. 📌 Use: Syncing, flashing software. 5️⃣ ID / CC Line 🔌 Function: Detects cable type and device connection. 📌 Use: Fast charging or OTG detection. ⸻ ⚙️ How Mobile Charging Works 1. Charger sends 5V power through VBUS. 2. Ground line completes the circuit. 3. Phone charging IC controls voltage and current. 4. Battery starts storing energy. 5.
