The Xiaomi Redmi Note 15 5G is a well-balanced midrange phone that focuses on display quality, durability, and long-term software support. It features a large 6.77-inch AMOLED panel with a 120Hz refresh rate, ultra-high PWM dimming, and very high peak brightness, making it excellent for both indoor and outdoor use.
The phone is slim and lightweight, yet rugged, with IP66 dust and water resistance and drop protection, which is uncommon at this price point. Powered by the Snapdragon 6 Gen 3 and running HyperOS 2 on Android 15, it offers smooth daily performance with a promise of up to four major Android upgrades.
Photography is led by a 108MP main camera with OIS that delivers sharp, stable photos and supports 4K video, while the 8MP ultra-wide adds flexibility for landscapes. Stereo speakers with Dolby Atmos, an under-display fingerprint scanner, NFC, and an infrared blaster round out the feature set, though the headphone jack is missing. The 5520mAh silicon-carbon battery comfortably lasts a full day or more and supports 45W fast charging along with reverse wired charging. Overall, the Redmi Note 15 5G is a strong all-rounder that prioritizes screen quality, camera resolution, and durability over raw flagship power.
