📌 What is a Mobile Phone Schematic Diagram?

A schematic diagram is a graphical representation of an electronic circuit.

It shows how components like resistors, capacitors, ICs, and connectors are connected on the board.

📚 Why Learn to Read Schematics?

• Helps in diagnosing hardware issues
• Saves time in troubleshooting
• Improves your understanding of board-level repair

🔍 Key Symbols You Should Know

• GND (Ground): Usually marked with a downward triangle
• VCC / VBAT: Main power lines
• Resistor (R), Capacitor (C), Inductor (L)
• U, Q, D labels: Indicate ICs, transistors, diodes

🧭 Following a Path in a Schematic

Start from the battery input, trace the voltage line, check for filters or protection ICs, and identify where the current flow might be interrupted.

✅ Practical Tip

Use a multimeter alongside the schematic to test continuity and voltage levels on each section of the board.
