Xiaomi has officially cemented its status as a mid-range titan. As of December 18, 2025, the REDMI Note Series has surpassed a staggering 460 million global shipments. This milestone is a key driver in Xiaomi’s journey toward becoming a global electronics powerhouse, contributing significantly to the brand’s 1 billion total smartphone shipments reached in late 2023.
From its first global appearance in Singapore 12 years ago—where it sold 5,000 units in a single minute—to its current presence in over 100 countries, the Note Series has consistently “democratized” flagship tech. Now, with the launch of the REDMI Note 15 Series, Xiaomi is using its $3.3 billion R&D investment (from 2025 alone) to bring “Titan Tough” durability to the masses.
Evolution of the “King of Mid-Range”
| Milestone Year | Model / Event | Industry Shift |
| 2014 | First REDMI Note | Set the “Large Screen + Big Battery” blueprint. |
| 2019 | REDMI Note 7 | Brought 48MP cameras to the affordable segment. |
| 2023 | REDMI Note 12 Pro+ | First 200MP camera with OIS in its class. |
| 2024 | REDMI Note 14 Pro+ | Standardized IP68 water resistance in mid-range. |
| 2026 | REDMI Note 15 Series | Introduced Titan Durability & IP69K protection. |
Built by Global R&D, Tested in the Real World
Behind those 460 million units is a massive infrastructure of 730+ laboratories worldwide. This has allowed Xiaomi to develop the Xiaomi IceLoop cooling system and Silicon-Carbon batteries found in the Note 15 Series—tech that used to be exclusive to $1,000+ flagships.
“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.” — Cynthia Chen, REDMI Marketing Director
REDMI Note 15 Series: The “Titan Tough” Legend Lands in PH
Xiaomi is officially moving the goalposts for mid-range durability. The REDMI Note 15 Series has just launched in the Philippines, bringing with it the new REDMI Titan Durability standard. We aren’t just talking about simple splash resistance; the flagship Pro+ 5G variant features a staggering IP69K rating—meaning it can survive high-pressure, high-temperature water jets, and can withstand drops from up to 2.5 meters.
The lineup is also a battery beast. The Pro+ model introduces Silicon-Carbon battery technology, packing a massive 6,500mAh capacity into a slim frame, paired with 100W HyperCharge that can get you to 100% in about 40 minutes. For the first time, REDMI is also offering a 4-year battery replacement warranty, signaling massive confidence in their new cells.
