iPad Not Charging? Here’s How to Check Charging Faults After Port & Battery Replacement | AppleFix Hamilton NZ
Have you replaced your iPad charging port and battery, but it’s still not charging? You’re not alone — this is one of the most common challenges we see at AppleFix Hamilton, the iPad repair experts in New Zealand.
Many customers (and even some technicians) assume a faulty port or battery is always the cause. However, when the charging port has been soldered correctly and the iPad still won’t charge, it often points to logic-board level issues or power-management faults deep inside the device.
⚡ Common iPad Charging Fault Scenarios
1️⃣ Replaced port and battery, but no charge – device doesn’t show charging symbol.
2️⃣ Intermittent charging – charges briefly, then disconnects.
3️⃣ Overheating or “accessory not supported” error.
4️⃣ Charging only via one side of the cable.
5️⃣ Completely dead, no power even after new battery.
If you’re facing any of these issues, watch our full diagnostic video on “How to Check iPad Charging Port and Logic-Board Faults” to see the proper testing process step-by-step.
🔍 How to Check if the Charging Port Is Soldered Correctly
-
Visual Inspection – Use magnification to ensure all port pins are aligned with pads and solder joints are shiny (not cold or cracked).
-
Continuity Testing – With a multimeter, check each VBUS and GND pin.
-
Data-line Signal Check – Ensure D+ and D- lines are not shorted.
-
Power Measurement – Measure voltage on the main power line; if absent, the issue could be a blown filter or shorted capacitor near the charging circuit.
-
Board Flexing – If the iPad charges when the board is slightly flexed, there may be micro-fractures under the port pads.
If everything above checks out, yet the device still doesn’t charge, the problem likely lies beyond the port.
🧠 Why an iPad May Still Not Charge After Port Replacement
-
Tristar / Tigris IC failure – These chips regulate charging voltage.
-
Shorted capacitor or line corrosion due to liquid exposure.
-
Faulty charging filter or damaged PP_VBUS line.
-
Faulty USB controller or PMIC (Power Management IC).
These are board-level repairs that require micro-soldering equipment and expert skills. At AppleFix Hamilton, we specialize in logic-board and liquid-damage repair, restoring iPads that most shops consider “beyond repair.”
