Xiaomi, the world's third-largest smartphone maker with a 14% global market share in the third quarter of 2025, has grown beyond its reputation as a handset brand into a broad consumer electronics powerhouse spanning smartphones, electric vehicles and home appliances. The expansion is driven by its "Huma x Car x Home" smart ecosystem strategy, which integrates devices across everyday life.
As of September 2025, Xiaomi reported more than 740 million global monthly active users. Amajor driver of that growth has been its REDMI brand, which reached a cumulative milestone of one billion smartphone shipments in 2023. Within that portfolio, the REDMI Note Series has emerged as a cornerstone, recording more than 460 million units shipped across over 100 countries by December 18, 2025. Building on this momentum, Xiaomi is preparing to unveil the REDMI Note 15 Series this month.
“Over the past decade, the REDMI Note Series has earned the trust of users across global markets, and this is inseparable from Xiaomi’s long-term investment in research and development,” said Cynthia Chen, REDMI Marketing Director at Xiaomi Global Marketing Department. “Since the series first launched in Singapore 12 years ago, we have continuously advanced performance, quality, and accessibility at scale. This month, we’re excited to introduce the latest REDMI Note 15 Series to audiences around the world.”
First launched globally in Singapore in 2014, the REDMI Note Series quickly established its appeal, selling 5,000 units in under a minute. Later that year in India, initial stock sold out in just eight seconds, highlighting strong demand for devices that combined large displays, long battery life and competitive pricing. The early success laid the foundation for rapid international expansion.
Between 2017 and 2018, the series entered new regions, debuting in Mexico as Xiaomi’s gateway to Latin America and later launching in Spain as its first European market. Today, REDMI Note devices are sold in more than 100 countries through a mix of physical stores, online platforms and carrier partnerships.
Beyond geographic reach, the series has focused on redefining the mid-range smartphone segment by introducing features once reserved for premium models. Innovations such as high-resolution cameras, fast charging and advanced imaging systems have helped narrow the gap between mid-range and flagship devices, reinforcing Xiaomi’s “Innovation for Everyone” philosophy.
Durability has also been a growing focus. Over successive generations, the REDMI Note lineup has introduced stronger glass protection, splash and water resistance, and reinforced designs, culminating in recent models that meet flagship-level durability standards for everyday use.
The upcoming REDMI Note 15 Series represents the next stage of this evolution. Launching globally this month, it introduces enhanced durability, longer battery life and a wider range of flagship-grade technologies, including advanced cooling systems, new battery materials and AI-powered features. At the top end, the REDMI Note 15 Pro+ 5G offers a new 200MP camera and comprehensive dust and water resistance certifications.
Xiaomi says these advances are supported by sustained investment in research, development and manufacturing. The company invested RMB 23.5 billion in R&D in the first three quarters of 2025 and plans to raise that figure to RMB 40 billion in 2026, supported by more than 730 laboratories worldwide and a growing network of smart factories.
With shipments now exceeding 460 million units, the REDMI Note Series continues to anchor Xiaomi’s global growth. The launch of the REDMI Note 15 Series in Nigeria marks the latest step in that journey, as the company seeks to further raise standards for accessible, high-performance smartphones.
