With Android 15 running HyperOS 2 out of the box, the Redmi Note 15 is clearly designed for users who want a smooth and future-ready smartphone experience.
Design and Build Quality
The Redmi Note 15 stands out with its slim 7.4mm profile and lightweight 178-gram body, making it comfortable to hold and use for long periods. The design feels clean and modern, with a focus on ergonomics rather than flashy elements. Xiaomi has also added an IP68 rating, which means the device is dust-tight and can survive water immersion up to 1.5 meters for 30 minutes. This level of protection is rare in its segment and adds significant peace of mind for everyday use.
The phone uses Xiaomi Dragon Crystal Glass on the front, enhancing scratch resistance and durability. Combined with a sturdy frame and well-balanced weight distribution, the Redmi Note 15 feels both premium and practical in hand.

The panel supports an impressive 68 billion colors, ensuring rich gradients and accurate color reproduction.
The 120Hz refresh rate makes scrolling and animations feel smooth and responsive, enhancing everyday interactions and gaming performance. With a peak brightness of up to 3200 nits, the display remains clearly visible even under direct sunlight. The high screen-to-body ratio further enhances the immersive viewing experience, making the Redmi Note 15 well-suited for streaming, browsing, and gaming.

Daily tasks such as multitasking, app switching, and media consumption feel smooth and reliable.
The Adreno 710 GPU handles casual and moderate gaming comfortably, offering stable frame rates in popular titles. While it is not designed for extreme gaming workloads, it performs well for its category and remains thermally efficient.
On the software side, the phone runs Android 15 with HyperOS 2, Xiaomi’s refined user interface that emphasizes smooth animations, better resource management, and improved system stability. The interface feels polished and customizable, catering to both power users and those who prefer a clean, straightforward experience.
