Glenn Ongena, since you already changed teh battery and the dock connector you should check all the charging components. This could be caused by a failed/damaged charging coil. Check for any physical damage, or if you have the knowledge and tools, check for function. You want to start by checking 3 inductors. For that, of course, you need a multimeter, or at least an ohm meter, to check for continuity. I hate to refer to those as fuses, but they most certainly control part of the charging circuit. First one is reference designator L3, it is a FERR-120-OHM-1.5A inductor. L4, right below it , has the identical value. Next would be the charger inductor L28 2.2UH-1.8A-155MOHM. All of these are pretty much available at mouser. com or Check the Diode D604, located just above L28. Hope this helps, good luck.

Thank you for your detailed comment.

L3 and L4 are good. L28 I need to remove the metal protector. Before I do that, if L28 is broken. Is it possible to fix it? And I mean by a normal person. I have ICT and ectricity degrees.


YEs it is but will require decent tools and good soldering skills (hot air soldering preferred:-)


oldturkey03 thank you for sharing such detailed knowledge.
