Features and Specifications
The Redmi 15 5G is a large phone with a 6.9-inch Full HD+ LCD screen. One of the most eye-catching features is the 144Hz AdaptiveSync refresh rate, which is rare in this segment. The display is also TÜV Rheinland certified for low blue light, flicker-free visuals, and circadian-friendly viewing, all designed to make long screen time a little easier on the eyes.
Inside, the phone runs on Qualcomm’s Snapdragon 6s Gen 3, a 6nm chipset that balances efficiency and performance while supporting 5G. Buyers can choose from three configurations: 6GB RAM with 128GB storage, 8GB RAM with 128GB storage, and 8GB RAM with 256GB storage. For those who need more space, storage expansion of up to 1TB is possible via microSD, and the system also supports up to 8GB of virtual RAM.
The battery is perhaps the most striking feature. The Redmi 15 5G comes with a 7,000 mAh silicon-carbon battery, which Xiaomi says is the largest in its class. It supports 33W fast charging, with the charger included in the box, and also offers 18W reverse wired charging so the phone can act as a power bank. The company claims the battery will retain up to 80 percent capacity after four years of use, backed by a life cycle of 1600 charges.
For cameras, the phone includes a 50MP primary sensor paired with a secondary lens, while the front camera is 8MP for selfies and calls. Camera software brings features such as AI Erase and AI Sky. On the software side, it ships with HyperOS 2.0 based on Android 15. Xiaomi has committed to two major OS updates and four years of security patches, which should give buyers some reassurance on long-term support.
Other details include a side-mounted fingerprint sensor, an IR blaster for controlling appliances, and an IP64 rating for splash and dust resistance. Sound is delivered through a single bottom-firing speaker with Dolby certification. It is not a stereo setup, but considering the price point, it feels acceptable.
