Xiaomi Redmi 15

Xiaomi positions the Redmi 15 5G as a big-screen everyday performer with long battery life and contemporary connectivity. It’s built around a 6.9-inch FHD+ DotDisplay at 2340 × 1080 with a dense 374 ppi, delivering crisp text and clean edges on icons and video. Motion handling is a highlight at this price tier, with a refresh rate that can step up to 144 Hz in supported apps and a touch sampling rate up to 288 Hz for snappy responses in fast-paced games and scrolling. Outdoor readability is supported by 700 nits typical brightness and 850 nits High Brightness Mode, while Reading mode and TÜV Rheinland certifications for Low Blue Light (software), Circadian Friendly and Flicker Free aim to reduce visual fatigue during longer sessions.

Under the hood sits Qualcomm’s Snapdragon 6s Gen 3 Mobile Platform, built on a 6 nm process with an octa-core Kryo CPU up to 2.3 GHz and Adreno graphics. Memory and storage options are straightforward: 4 GB + 128 GB or 8 GB + 256 GB, using LPDDR4X RAM and UFS 2.2 storage. There’s flexibility if you need more headroom, with Memory extension available (up to 16 GB on the 8 GB model by using part of the storage) and a microSD slot that supports cards up to 2 TB. The SIM tray is a hybrid design (SIM1 + Hybrid), letting you choose between dual-SIM or a single SIM plus microSD.

Endurance is a central pillar of the experience. A 7,000 mAh (typical) battery anchors the device, pairing capacity with 33 W fast charging. There’s no power adapter in the box, so you’ll want to use a PD-compatible 33 W charger or Xiaomi’s own 33 W adapter to reach advertised speeds. For security and convenience, a side-mounted fingerprint sensor is complemented by AI face unlock, so you can tap or glance to get going.

Photography is handled by a 50 MP main rear camera using a 5P lens with an f/1.8 aperture, accompanied by an auxiliary lens. Video capture on the rear and front tops out at 1080p at 30 fps or 720p at 30 fps. On the front, an 8 MP camera covers selfies and video calls, and you’ll find useful shooting modes such as HDR, Portrait mode and Time-lapse. There’s also a soft-light ring for more flattering front-camera shots in dim environments and a “filmCamera” mode to add a creative twist to your clips.

Connectivity options cover modern essentials. 5G is on board (with SA and NSA support; exact bands vary by region and carrier), backed by 4G LTE FDD/TDD, plus dual-band Wi-Fi (2.4 GHz and 5 GHz) and Bluetooth 5.1. NFC is supported, though availability depends on the market. For navigation, the phone works with GPS, Glonass, Galileo and Beidou, providing broad satellite coverage for maps and fitness apps. Audio is a pleasant surprise at this level, with Dolby Atmos and Hi-Res Audio support elevating sound for streaming and games through compatible headphones or speakers. A handy IR blaster rounds out the utilities, letting the handset double as a remote for supported appliances.

Durability and ergonomics haven’t been overlooked. The device carries an IP64 rating, offering dust resistance and protection against splashes in line with laboratory testing (as always, day-to-day wear can affect resistance and liquid damage isn’t covered under warranty). The chassis measures 169.48 × 80.45 × 8.40 mm and weighs 217 g, giving it a substantial yet manageable in-hand feel for a large-screen phone. Colour options referenced with the product include Ripple Green, Titan Gray and Midnight Black, complemented by a protective case included in the box. You’ll also find a USB-C cable, SIM eject tool, safety information, a quick start guide and a warranty card in the package; contents can vary by region.

On the software side, Xiaomi HyperOS 2 is preinstalled, with the usual caveat that features and services can vary by version and model. Day to day, that means a clean, responsive interface with Xiaomi’s ecosystem integrations and the latest platform refinements.

Taken together, the Redmi 15 5G focuses on three things that matter to everyday use: a very large, smooth display; a battery sized for long stints between charges; and connectivity that’s current and capable. Add in expandable storage, practical biometrics, Dolby Atmos audio and splash protection, and it lands as a confident all-rounder for those who want a big screen and big stamina without unnecessary complexity.
