DHAKA, Bangladesh — September 21, 2025:
Xiaomi has officially introduced the REDMI 15 to the Bangladeshi market, bringing with it one of the largest smartphone batteries ever released in the country. The REDMI 15 is equipped with a massive 7000mAh battery, designed to offer up to two full days of uninterrupted use on a single charge. This leap in battery capacity addresses a growing demand among users for smartphones that can support heavy daily use, extended streaming, long gaming sessions, and travel without requiring constant recharging.
Complementing its large battery, the device also supports 33W fast charging, drastically reducing downtime and allowing users to power up quickly. Xiaomi has positioned this phone as a reliable daily driver for both productivity and entertainment, especially for those who prioritize all-day usage without access to frequent charging points.
What sets the REDMI 15 further apart is its 18W reverse charging feature, turning the smartphone into a portable power bank. This allows users to charge other devices directly from their phone, such as wearables, earbuds, or another smartphone. With this multi-functionality, the REDMI 15 is tailored for users who live a fast-paced lifestyle and need their phone to keep up with more than just communication.
Powering the REDMI 15 is the Qualcomm Snapdragon 685 processor, a chip known for its balance of performance and power efficiency. Combined with the phone’s advanced thermal management, users can expect smooth multitasking, gaming, and video playback without the device overheating or draining too quickly.
Visually, the smartphone features a 6.9-inch Full HD+ display with a 144Hz refresh rate, delivering sharp, fluid visuals that enhance everything from video streaming to gaming. The display includes adaptive brightness technology, adjusting automatically to ambient light conditions for better eye comfort during prolonged use, whether under the sun or in low light.
Photography on the REDMI 15 is powered by a 50MP AI dual camera system, offering clear, high-resolution images even in low-light scenarios. The 8MP front camera provides clean selfies and smooth video calls, enhanced by built-in AI beautification features. For users who value digital security, the device includes AI face unlock and a responsive side-mounted fingerprint scanner, offering both convenience and peace of mind.
Built to handle real-world conditions, the REDMI 15 also comes with an IP64 rating for dust and water resistance. This durability ensures the phone can withstand light splashes and challenging environments, making it suitable for both urban use and outdoor excursions.
The smartphone’s physical design combines functionality with modern aesthetics. Its quad-curved body makes it ergonomic and comfortable in hand, while the sleek finish is available in three colors: Sandy Purple, Titan Grey, and Midnight Black.
Xiaomi’s Country General Manager in Bangladesh, Ziauddin Chowdhury, described the REDMI 15 as a major step forward in battery innovation. He emphasized that the combination of an ultra-high-capacity battery and a reliable chipset was designed to deliver consistent, long-lasting performance to meet the needs of Bangladeshi consumers.
The REDMI 15 is now available in authorized Xiaomi outlets nationwide and is expected to be a strong performer in the market segment where endurance and fast charging matter most.
