Xiaomi Redmi 15 Specifications

The Xiaomi Redmi 15 was announced and released on August 1, 2025, and it comes in both 5G and 4G variants, targeting users who want a big screen, strong battery life, and modern software at a budget price. Both models feature a large body with an IP64 rating, meaning they are protected against dust and light water splashes. The 5G variant measures 169.5 × 80.5 × 8.4 mm and weighs 217 g, while the 4G version is slightly bigger and heavier at 171.1 × 82.1 × 8.6 mm and 224 g. The 5G model uses Gorilla Glass 3 on the front for extra protection, while both phones come with a plastic frame and back. Color options include Midnight Black and Titan Gray, with Ripple Green exclusive to the 5G model and Sandy Purple available on the 4G version.

The highlight of both phones is the massive 6.9-inch IPS LCD display with a 144Hz refresh rate, which is rare in this segment. The resolution is 1080 × 2340 pixels, offering a sharp ~374 ppi density, making text and videos look clean and detailed. The 5G variant stands out with higher brightness levels, reaching up to 850 nits peak, which helps with outdoor visibility. Both phones run Android 15, with the 5G model using HyperOS 2.2 and the 4G version running HyperOS 2. Performance-wise, the 5G model is powered by the Snapdragon 6s Gen 3 (6 nm) paired with the Adreno 619 GPU, delivering smoother multitasking and better long-term performance. The 4G variant uses the Snapdragon 685 with Adreno 610, which is suitable for daily tasks but less powerful overall. Multiple RAM and storage options are available, going up to 8GB RAM and 256GB storage, along with microSD support.

In the camera department, both variants use a 50 MP main camera with PDAF, supported by an auxiliary lens. The camera performs well in daylight, with decent HDR, while video recording is limited to 1080p at 30fps. The 8 MP front camera is fine for selfies and video calls. One of the biggest strengths of the Redmi 15 series is the huge 7000 mAh battery, which easily lasts more than a day of heavy use. Both models support 33W fast charging, and the 5G variant even adds 18W reverse wired charging, which is useful for emergencies. Connectivity features are solid, with Wi-Fi ac, Bluetooth, NFC, infrared, and a side-mounted fingerprint scanner. Pricing is aggressive, starting around $178 (Rs 15,999 in India) for the 5G model and $122 (Rs 10,999 in India) for the 4G version, making the Redmi 15 a strong choice for users who value battery life, display smoothness, and modern software at an affordable price.
