TECNO SPARK 5 Air Charging Problem Solution | Not Charging, Slow Charging, or Fake Charging Fix

If your TECNO Spark 5 Air is not charging, charges slowly, or shows charging without actually increasing battery percentage (fake charging), the issue may be caused by a faulty charging port, damaged sub-board, battery problem, or motherboard fault like a defective charging IC.

🔧 In This Guide You Will Learn:
How to test the charging cable and adapter to rule out external issues

How to inspect and clean the charging port (use isopropyl alcohol and a soft brush)

How to check and replace the charging sub-board (usually includes the port, mic, and components)

How to test the battery health using a multimeter or battery tester

How to measure voltage on charging lines to confirm if power reaches the motherboard

How to identify and replace a faulty charging IC or perform jumper if required

✅ Pro Tips:
Always disconnect the battery before replacing the charging port or sub-board.

If you see moisture or corrosion inside the port, clean it thoroughly before replacing anything.

If the battery drains quickly even after charging, consider battery replacement.

For motherboard-level issues, use ZXW tool or boardview to trace charging lines.
