Redmi is a budget smartphone line manufactured by Xiaomi, that was first announced in July 2013.[1] Redmi phones use the Xiaomi MIUI operating system, a variant of Android. Models can be divided into regular RedMi phones with screens usually up to 5" and RedMi Note series with displays exceeding 5". Only phone besides these two series is Redmi Pro, first introduced in 2016 with Dual Camera system, USB-C and unique for Xiaomi devices OLED display. Redmi phones have been marketed in several Asian and European countries.The most significant difference from other Xiaomi smartphones is that it uses less-expensive components and thus is more cost-effective. In August 2014 The Wall Street Journal reported that in the second quarter of the 2014 fiscal year Xiaomi smartphone shipment rankings in China with a market share of 14%.[2] Redmi sales were attributed as a contributing factor toward this gain in shipment rankings.[2]

2013[edit]

The Redmi phone release in 2013 was first announced on Xiaomi's website, with consumer sales beginning on July 12, 2013.

2014[edit]

On March 13, 2014, Redmi phones were announced to be sold out, in Singapore alone, eight minutes[3] after being purveyed to consumers on Xiaomi's website.
