iTunes recognizes it while connected, but cannot charge.
Maybe someone had a similar experience and can help.
Initially I had problems with the display just going dead (like the power suddenly cut off and display got fuzzy then black). What usually happened afterwards was that the apple logo would appear and the only way to get back into the home screen was doing a soft reset. These crashes got more frequent as I tried using the Safari app, running simple web surfing .
Thinking the battery was bad, I replaced it. But it seems I fixed one problem, but happened on another: the battery will not charge by PC, not by wall charger.
It seems that I can trick it into charging if I connect the iPhone to the PC and shut down my computer and then reboot it. However this is short-lived as it only charges up to about maybe 20% and back to square one. The iPhone operates normally but its so annoying that I cannot seem to fully charge the battery, even if I " trick " it into charging.
Oddly enough, I think it's strange that iTunes recognizes it but it doesn't charge. No charge status shown in the indicator icon. (Unless I " trick " it with rebooting PC). I've been able to restore it fully to factory settings twice ( iOS 6.1.6) , but the non-charging battery problem persists.
I got another 3GS with "proven" components and tried to swap them out with the problem one. Using parts from the proven one , I had No luck with changing the dock connector, the battery, nor the display assembly. In other words, the problem remains, which worries me to think that something may be wrong with the system board.
Would there be another way to fix this problem? Is there a way to test the system board for faults?
Your thoughts are appreciated , thanks.
