Xiaomi has been well known to offer specs-heavy smartphones in an affordable price bracket. Similar is the case for the sub-brand Redmi. As such, Redmi Note 15 4G is the company's midrange offering for the year 2025/26.Redmi Note 15 4G Overview:Design and DisplayThe Redmi Note 15 4G offers slight improvements over last year’s Note 14 4G.

The display is a 6.77-inch AMOLED panel with a 120Hz refresh rate.PerformanceAt its core, the phone is powered by the Helio G100 Ultra SoC, a mildly refreshed version of the Helio G99, though the real-world performance difference is barely noticeable. In terms of memory, the lineup starts with a 6GB RAM and 128GB storage variant and goes up to an 8GB RAM and 256GB option. On the software side, the Redmi Note 14 4G runs Xiaomi’s HyperOS, built on Android 14.OpticsOn the camera front, the Note 15 4G sticks to a dual-camera setup this year. The earlier 8MP ultrawide is gone, leaving a 108MP primary sensor paired with a largely forgettable 2MP auxiliary lens. That said, Xiaomi’s HyperOS 2 does sprinkle in a bit of AI magic, with features like AI Erase, AI Sky, and a few other software-driven tricks to play around withBattery and OthersKeeping the lights on is a massive 6000mAh battery paired with 33W fast wired charging. For connectivity, the Note 15 4G covers all the essentials with 4G support, dual-band Wi-Fi 5, Bluetooth 5.1, GPS, a USB Type-C port, and even a 3.5mm headphone jack. Rounding things off are practical extras like an in-display fingerprint scanner and dual stereo speakers tuned with Dolby Atmos.
