iPad Air 4 Charging Port Replacement & Not Charging Diagnosis Guide

If your iPad Air 4 (A2316, A2324, A2325, A2072) shows the battery icon but doesn’t charge, the problem is often a damaged charging port or logic-board fault. Before spending on a new device, follow this detailed guide to diagnose and repair the issue correctly.

Common Charging Problems

• iPad shows charging symbol but battery percentage doesn’t increase
• Loose or damaged USB-C charging port
• Corrosion or liquid damage near connector
• Faulty charging IC or power filter on logic board
• Broken flex cable after impact or drop

How to Diagnose Not-Charging Issues

1. Check charger and cable: use an original Apple adapter and certified USB-C cable.
2. Inspect charging port: look for dust, bent pins or moisture damage.
3. Test battery voltage: low voltage means charging isn’t reaching the battery.
4. Connect to Mac or Finder: if detected but not charging, the port or logic board is faulty.
5. Thermal test: if the port area gets hot, the charging IC may be shorted.

How to Disassemble iPad Air 4 / Air 5

1. Power off the iPad completely.
2. Heat edges to soften the front adhesive (70–80 °C).
3. Gently lift the display using plastic picks and disconnect the battery and screen flex.
4. Remove the screws near the USB-C charging port.
5. Disconnect the charging-port flex cable from the board.

Charging Port Replacement Procedure

• Apply heat to loosen the adhesive under the flex.
• Desolder the damaged USB-C port using a hot-air station.
• Clean pads with flux and solder wick.
• Align and solder the new port carefully to each pin.
• Test continuity for Vbus, GND, and signal lines.
• Reassemble and test charging function.

If charging still fails, the issue may involve the CD3215, Tristar, or PMIC chip on the logic board — which requires microsoldering skills and advanced diagnostic tools.
