The new PCH-2000 series system is a lighter redesign of the device that was announced at the SCEJA Press Conference in September 2013 prior to the Tokyo Game Show. The PCH-2000 series is commonly referred to as either the PS Vita Slim or the PS Vita 2000. The PS Vita Slim was released in Japan on October 10, 2013 in six colors (white, black, light blue, lime green, pink, and khaki). On February 7, 2014, the new model was released in the UK, initially only in black and with a recommended retail price of £180. This model is 20% thinner and 15% lighter compared to the original model. It has an additional hour of battery life, which is most likely due to the switch from an OLED display to an LCD display. Some users have reported significant increase in battery life, even above what Sony stated in their original press release. This model has a micro USB Type B port, which can be used to charge the device along with any standard micro USB cable. The PS Vita Slim has 1GB of internal storage memory. Users are unable to use the 1GB internal memory and any expandable storage simultaneously, as access to the internal memory is only possible if no memory card is inserted. Upon inserting a PS Vita memory card, the system will offer to copy the existing data from the internal memory to the new card. PCH-2000 was released in Japan on October 10, 2013, in Europe on February 7, 2014 and in North America on May 6, 2014.
