If you use the right kind of USB port but iPhone is still not charging, it would probably be that the USB port itself it broken. You can test this by plugging your iPhone into another USB port on your computer (or on another computer nearby). If your iPhone is recognized by computer with this way, then there may be something wrong with the previous USB port.
