Yes. And now for some history:
As of 14 June 2007, all new mobile phones applying for a license in China are required to be able to use a USB port as a power port for battery charging.
In September 2007, the Open Mobile Terminal Platform group (a forum of mobile network operators and manufacturers such as Nokia, Samsung, Motorola, Sony Ericsson and LG) announced that its members had agreed on micro-USB as the future common connector for mobile devices.
On 17 February 2009, the GSM Association (GSMA) announced that they had agreed on a standard charger for mobile phones. The standard connector to be adopted by manufacturers including Nokia, Motorola and Samsung is to be the micro-USB connector (several media reports erroneously reported this as the mini-USB). The new chargers will be much more efficient than existing chargers. Having a standard charger for all phones means that manufacturers will no longer have to supply a charger with every new phone. The basis of the GSMA's Universal Charging Solution (UCS) is the technical recommendation from OMTP and the USB-IF battery charging standard.
On 22 April 2009, this was further endorsed by the CTIA ? The Wireless Association.[56]
On 22 October 2009, the International Telecommunication Union (ITU) announced that it had embraced the Universal Charging Solution as its "energy-efficient one-charger-fits-all new mobile phone solution", and added: "Based on the Micro-USB interface, UCS chargers will also include a 4-star or higher efficiency rating?up to three times more energy-efficient than an unrated charger".
In June 2009, many of the world's largest mobile phone manufacturers signed an EC-sponsored Memorandum of Understanding (MoU), agreeing to make most data-enabled mobile phones marketed in the European Union compatible with a common External Power Supply (EPS). The EU's common EPS specification (EN 62684:2010) references the USB Battery Charging standard and is similar to the GSMA/OMTP and Chinese charging solutions.
