The Micro-USB connections are intended to replace the Mini-USB plugs used in new
devices including Smartphones and Personal Digital Assistants (PDA). This
Micro-USB plug is rated for 10,000 connect-disconnect cycles. It is about half
the height of the mini-USB connector, but features a similar width. In the
Universal Serial Bus Micro-USB Cables and Connectors Specification, details have
been laid down for Micro-A plugs, Micro-AB receptacles, and Micro-B plugs and
receptacles, along with a Standard-A receptacle to Micro-A plug adapter.
The carrier led group OMTP have recently endorsed micro-USB as the
standard connector for data and power on mobile devices. These include various
types of battery chargers, allowing Micro-USB to be the single external cable
link needed by some devices
