Xiaomi Redmi 15 redefines budget phones with a massive 7000mAh battery, a smooth 144Hz display, and robust 5G performance.
Introduction
Xiaomi's Redmi 15 enters the competitive budget segment with a compelling proposition: exceptional battery life. Anchored by a massive 7000mAh cell, this phone is built for users who prioritize longevity. It combines this standout feature with a high-refresh-rate display and modern 5G connectivity, aiming to deliver maximum value at an accessible price point.
Design & Display
The device features a large 6.9-inch IPS LCD screen with a Full HD+ resolution of 1080 x 2340 pixels. Its most impressive visual feature is the 144Hz refresh rate, which ensures buttery-smooth scrolling and responsive touch interactions. Protected by Corning Gorilla Glass 3, the display reaches a peak brightness of 850 nits for reasonable outdoor visibility. The phone carries an IP64 rating, making it resistant to dust and water splashes. It is available in Black, Gray, and Green finishes.
Performance & Hardware
Driving the Redmi 15 is the Qualcomm Snapdragon 6s Gen 3 platform, an octa-core chip built on a 6nm process. It is paired with the Adreno 619 GPU, providing sufficient power for everyday tasks and casual gaming. The phone offers multiple configurations: 4GB, 6GB, or 8GB of LPDDR4X RAM, coupled with 128GB or 256GB of UFS 2.2 storage. A microSDXC card slot is available for further storage expansion.
Camera
The camera system is practical for its class. The dual rear array consists of a 50MP primary sensor with phase detection autofocus (PDAF) and an f/1.8 aperture, accompanied by a basic 0.08MP auxiliary lens. Video recording is capped at 1080p at 30 frames per second. For selfies and video calls, an 8MP front-facing camera is housed in a center-aligned punch-hole.
Battery & Charging
The headline feature is 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 like earbuds or smartwatches.
Software & Features
The Redmi 15 ships with the latest Android 15, overlaid with Xiaomi's HyperOS 2.2. This software brings features like Circle to Search for enhanced usability. Security is handled by a responsive side-mounted fingerprint sensor. Other sensors include an accelerometer, compass, and a virtual proximity sensor.
Connectivity & Network
Connectivity is a strong suit. The phone supports a vast array of 5G bands, ensuring wide compatibility with networks globally. It also features dual-band Wi-Fi 5, Bluetooth 5.1, NFC for contactless payments, and a USB Type-C 2.0 port. GPS support is comprehensive, including BDS, GALILEO, GLONASS, and GPS. Notably, the 3.5mm headphone jack is absent, but the device supports high-resolution 24-bit/192kHz audio.
Price & Availability
The Xiaomi Redmi 15 is officially priced at approximately £220. It was released on Friday, August 1, 2025, and is currently available for purchase.
