OnePlus 15 Launched with Snapdragon 8 Elite Gen 5 and 7300mAh Battery

OnePlus unveiled its latest flagship smartphone, the OnePlus 15, at a launch event in London today, 13 November 2025. The company positions the new device as a “two-generation upgrade,” setting a new benchmark for performance-focused flagship models.

The OnePlus 15 is built around a comprehensive integration of high-end performance hardware, a professional-grade camera system, and newly introduced artificial intelligence capabilities. These core elements are packaged within a refined version of the brand’s iconic design. OnePlus states this synthesis of advancements aims to deliver a fluid and dependable experience for work, creativity, and daily use.

“At OnePlus, our philosophy has always been to push the boundaries of mobile technology to create devices that truly enhance our users’ lives,” said Celina Shi, Chief Marketing Officer of OnePlus Europe. “OnePlus 15 is the culmination of this belief. We have torn up the blueprint and delivered a device that is a two-generation leap in power, intelligence and design, further strengthening our focus on delivering a fast & smooth performance.”

A New Era of Mobile Power

OnePlus has placed a significant emphasis on the performance capabilities of the OnePlus 15, introducing an innovative triple-chip architecture designed to deliver unprecedented smoothness and responsiveness.

The Triple-Chip Architecture

At the heart of the new device is the Snapdragon 8 Elite Gen 5 Mobile Platform, which provides state-of-the-art CPU and GPU performance. This platform is engineered to handle seamless multitasking and demanding, immersive gaming sessions.

This primary processor is joined by two co-processors. The first is a dedicated touch response chip, which enables an industry-leading 3200Hz instant touch sampling rate. This technology is designed to deliver ultra-smooth visuals and unmatched responsiveness to user input. The second is an independent Wi-Fi chip, which has been engineered to provide stronger and more stable connections, particularly in congested environments where many networks are competing for signal. OnePlus states these three chips work in synergy to ensure a consistently smooth experience across all scenarios.

Advanced Thermal Management

To support this powerful hardware, the OnePlus 15 incorporates the 360 Cryo-Velocity Cooling System. This system uses aerospace-grade materials, including aerogel insulation and white graphite, to efficiently dissipate heat. This advanced cooling is crucial for maintaining stable and sustained performance during extended gaming sessions or other intensive tasks.

A New Benchmark in Display Technology

The device features an industry-first 1.5K 165Hz LTPO display. This combination aims to provide retina-level clarity and ultra-smooth motion simultaneously. The display supports a high brightness mode (HBM) of 1800 nits for clear visibility outdoors, and can also dim to as low as 1 nit for comfortable viewing in dark environments. The screen is certified by TÜV Rheinland for Intelligent Eye Care 5.0.

Precision Control for Gamers

For gaming enthusiasts, the OnePlus 15 includes a UAV-grade gyroscope. This high-sensitivity sensor offers ±4000 DPS precision, allowing it to accurately translate subtle hand movements into precise in-game control. The company claims this minimises drift and helps maintain a steady aim, even when using high-magnification scopes in games.

Power and Endurance Redefined

The performance hardware is supported by a new battery and charging system designed for both longevity and speed.

Groundbreaking Silicon NanoStack Battery

The OnePlus 15 is powered by a 7300mAh Silicon NanoStack Battery. This new battery technology features 15% silicon content. It is engineered for both high capacity and long-term reliability. OnePlus claims the battery will maintain over 80% of its health after four years of use. It is also rated to operate reliably in cold conditions, down to -20°C.

Rapid Charging Capabilities

To charge the high-capacity battery, the phone supports 120W SUPERVOOC wired charging. This technology is capable of restoring the battery to full power in approximately 39 minutes. Additionally, the device supports 50W AIRVOOC wireless charging, offering a fast and convenient alternative without cables.

Next-Generation Imaging System

OnePlus has introduced a new chapter in its imaging capabilities with a breakthrough computational engine and a versatile triple-camera array.

The Hardware: A Versatile 50MP Trio

The rear camera system consists of three 50-megapixel sensors:

• A 50MP main camera featuring optical image stabilisation (OIS) to reduce blur from hand movements.
• A 50MP ultra-wide camera which includes autofocus, allowing it to capture both expansive scenes and detailed close-up macro shots.
• A 50MP periscope telephoto lens that provides 3.5x optical zoom and a 7x high-quality lossless zoom.

Computational Enhancements with DetailMax Engine

This hardware is enhanced by the new DetailMax Engine, which uses intelligent computational photography to improve image quality. Software features include:

• Ultra Clear 26MP mode for capturing intricate details in daylight.
• Clear Burst for taking sharp, in-focus photos of moving subjects.
• Clear Night Engine for producing cleaner, brighter photos in low-light conditions.

Advanced Videography Features

For video creators, the OnePlus 15 is noted as the only Android device to support 4K 120fps Dolby Vision recording. It also includes support for LOG recording, which provides a flat colour profile for flexible post-production colour grading, and real-time LUT previews. These features are intended to give users enhanced creative control over their video content.

Intelligent and Fluid Software Experience

The device runs on OxygenOS 16, which builds on the brand’s “smart and smooth” foundation by introducing a suite of intelligent AI capabilities.

‘Plus Mind’: A Unified Knowledge Base

The new AI experience is centered around a feature called Plus Mind. Users can press a dedicated Plus Key or swipe up with three fingers to instantly save any on-screen content to a unified knowledge base called Mind Space.

Google Gemini is integrated with this feature and can connect with Mind Space to pull information and provide personalised suggestions based on the user’s saved content, all within a single prompt. For example, a user can ask for help creating a travel itinerary, and Gemini will access Mind Space to generate a plan based on the user’s own stored data.

A Suite of AI-Powered Tools

Additional AI tools include:

• AI Writer for assistance with content drafting and summarisation.
• AI Recorder for real-time meeting transcription with speaker identification.
• AI Portrait Glow for intelligent enhancement of portrait photos.

Eligible OnePlus users will also receive a three-month trial of Google AI Pro at no extra cost. This trial includes more access to new features in the Gemini app, higher usage limits in NotebookLM, and Gemini integration in Gmail, Docs, and more.

Core System Fluidity

Fluidity remains a core focus of the software. Parallel Processing 2.0 ensures system-wide smoothness during app switching, navigation, and multitasking. The interface features seamless motion animations to provide visual previews of transitions, creating a more responsive feel. A new Dual App Control feature enables the simultaneous operation of two applications on a single screen to enhance productivity.

Refined Design and Unprecedented Durability

OnePlus has updated its design language for the OnePlus 15, focusing on aesthetics, ergonomics, and resilience.

A Focus on Aesthetic Harmony

The rear camera system is meticulously arranged with geometric precision. On the front, the display features uniform 1.15mm ultra-slim bezels and rounded corners, creating an immersive viewing experience. This seamless design is enabled by advanced Low Injection Pressure Over-molding (LIPO) technology.

Ergonomics and Premium Finishes

The device features a flat frame with rounded edges, complemented by optimised 50/50 weight distribution for comfortable handling. The OnePlus 15 is available in three premium finishes:

• Infinite Black: Features advanced AG glass.
• Sand Storm: Features a groundbreaking MAO-treated frame that is claimed to be 3.4 times harder than conventional aluminium and 1.3 times more resilient than titanium.
• Ultra Violet: Features a light-responsive dual-texture coating.

Industry-Leading Protection

The OnePlus 15 sets a new standard for flagship durability with comprehensive IP66, IP68, IP69, and IP69K certifications. The company describes this as the “most complete protection system in the industry.” This extensive rating ensures exceptional resistance against dust, water immersion up to 2 metres for 30 minutes, and even high-pressure, high-temperature water jets up to 80°C.
