Xiaomi is now the world's third-largest smartphone manufacturer, and its meteoric rise over the last five years is directly attributable to strong sales in the Redmi Note series. To date, the brand has sold over 140 million phones in the Redmi Note series, with the Redmi Note 8 Pro becoming the best-selling Android phone globally in Q1 2020 and racking up 30 million sales. With the Redmi Note series, Xiaomi has commoditized features that have traditionally been limited to the mid-range or premium categories. When 4G was gaining momentum in emerging markets back in 2014, Xiaomi was at the forefront of delivering value. It has led the way for high-res cameras, multi-day battery life, and sleek designs on budget phones.
