Description

technical field [0001] Embodiments of the present invention relate to charging detection technology, and in particular to a system and method for writing charging flag bits. Background technique [0002] With the improvement of people's living standards and the popularization of communication devices, mobile terminals have become an indispensable communication and entertainment tool for people. [0003] When leaving the factory, it is necessary to detect whether the charging function of the mobile terminal is normal. When the charging integrated circuit (IC) on the mobile terminal does not have the function of current detection, on the mobile terminal charging function detection assembly line, after the detection device detects that the mobile terminal is successfully charged, it needs to write the charging flag to the mobile terminal. [0004] In the process of writing the charging flag to the mobile terminal, generally one detection device can only be connected to one mob...
