Xiaomi Redmi 15

Introduction

Xiaomi continues its legacy of value-packed smartphones with the Redmi 15. Launched in August 2025, this device aims to dominate the budget segment by combining a massive 7000mAh battery, a high-refresh-rate display, and modern 5G connectivity. It's designed for users who prioritize longevity and smooth performance without breaking the bank.

Design & Display

The Redmi 15 features a substantial 6.9-inch IPS LCD with a sharp 1080 x 2340 pixel resolution. Its standout feature is the incredibly smooth 144Hz refresh rate, which makes scrolling and animations feel exceptionally fluid. The display is protected by Corning Gorilla Glass 3 and reaches a peak brightness of 850 nits for decent outdoor visibility. With an IP64 rating, the phone offers protection against dust and water splashes, adding a layer of durability. It comes in Black, Gray, and Green color options.

Performance & Hardware

Under the hood, the Redmi 15 is powered by the Qualcomm Snapdragon 6s Gen 3 chipset, built on a 6nm process. This octa-core processor, paired with an Adreno 619 GPU, provides capable performance for everyday tasks and light gaming. Users can choose from multiple configurations: 4GB, 6GB, or 8GB of LPDDR4X RAM paired with 128GB or 256GB of UFS 2.2 storage. The storage is also expandable via a microSDXC card slot, offering flexibility for media-heavy users.

Camera

The camera system on the Redmi 15 is practical for its class. The dual rear setup is led by a 50MP primary sensor with an f/1.8 aperture and PDAF for focused shots. It is accompanied by a basic 0.08MP auxiliary lens. Video recording is capped at 1080p at 30fps. For selfies, there is an 8MP front-facing camera, also capable of 1080p video. The system supports HDR for better dynamic range in photos.

Battery & Charging

The headline feature is undoubtedly the enormous 7000mAh battery, which promises multi-day usage on a single charge. It supports 33W wired charging for relatively quick top-ups. A useful addition is support for reverse wired charging, allowing the phone to act as a power bank for other devices.

Software & Features

The device ships with Android 15 out of the box, overlaid with Xiaomi's HyperOS 2.2 user interface. It includes features like Circle to Search for enhanced usability. Security is handled by a side-mounted fingerprint sensor, and it also includes an accelerometer, compass, and a virtual proximity sensor.

Connectivity & Network

The Redmi 15 is a well-connected device, offering comprehensive 5G support across numerous bands (n1, n2, n3, n5, n7, n8, n12, n20, n26, n28, n38, n40, n41, n48, n66, n71, n77, n78). It also has dual-band Wi-Fi 5, Bluetooth 5.1, NFC, and a USB Type-C 2.0 port. GPS support includes multiple systems: BDS, GALILEO, GLONASS, and GPS. Notably, the phone lacks a 3.5mm headphone jack but supports high-resolution 24-bit/192kHz audio.
