How come iPhone needs usb cable in connector to function properly?
My iPhone 4 was taking a lot of time to charge and randomly shut down even when the battery supposedly was charged (high battery percentage in statusbar). I decided to replace the battery and uneventfully did that. For a couple of weeks the iPhone worked fine. After that the iPhone randomly began to shut down again, at first now and then, but later immediately after taking the Apple adapter cord out. So now the iPhone is constantly connected to a power outlet and can no longer be called a mobile device.
But....just today I found out that the iPhone also stays on when I unplug the cord from the power outlet as long as I keep the other end connected to the dock connector. Which means it is mobile again, but not really functional. I was wondering if this means the problem is caused by the dock connector and not the new battery. Or maybe something else, so I can try to fix it. Any suggestion would be highly appreciated!
Is this a good question?
