Apple released its opening weekend sales results for the 5C and 5S models, showing an all-time high for the product's sales figures, with nine million handsets sold—the previous record was set in 2012, when five million handsets were sold during the opening weekend of the 5 model. This was the first time that Apple has simultaneously launched two models and the inclusion of China in the list of markets contributed to the record sales result.[314] Apple also announced that, as of September 23, 2013[update], 200 million devices were running the iOS 7 update, making it the "fastest software upgrade in history."[315]
