As mobile phones and other smart devices become ever more smaller, the micro USB appears ideal to suit the sleeker designs. The micro USB is also more robust. Present designs made of stainless steel are supposed to withstand 10,000 insertions and extractions. The USB is designed to withstand stress both in fitment and removal.
In keeping with this development, the International Electrotechnical Commission (IEC) has released a standard the IEC 62684. This standard had been developed after discussions with the USB Implementers Forum. Major Manufactures of mobile phones such as Nokia, Samsung, LG, Research in Motion, Huawei had also given specifications which had been incorporated in the standard.
