Dock Flex Test Board for iPhone & Android – U2 IC, USB Charging & Battery Testing

The Dock Flex Test Board is a professional mobile phone diagnostic tool designed to test U2 IC, battery performance, charging ports, and USB charging circuits on compatible iPhone and Android smartphones. It allows technicians to perform essential charging-system checks without disassembling the phone, helping save valuable repair time and reducing unnecessary component removal.

Simply connect the test board directly to the phone’s charging/tail plug and use a multimeter in diode mode to compare measurements. The board is particularly useful for identifying whether a charging problem originates from the charging port, battery, U2/charging IC circuit, or related lines.
