OnePlus has announced the OnePlus 15, its latest flagship smartphone that focuses on delivering enhanced performance through advanced hardware configurations. The device launches globally on 13 November 2025, featuring a triple-chip architecture, an extended battery capacity, and a high refresh rate display designed to improve user experience across various applications.
Display Technology and Visual Performance
Industry-First 1.5K 165Hz LTPO Screen
The OnePlus 15 features a 6.78-inch display with a 1.5K resolution and 165Hz refresh rate using LTPO technology. This represents the first implementation of these specifications in the smartphone industry. The display supports native 165fps performance in select gaming titles including Call of Duty: Mobile, Brawl Stars, and Clash of Clans.
The screen delivers a high brightness mode of 1800 nits for outdoor visibility whilst maintaining colour accuracy. For low-light conditions, the display can reduce brightness to 1 nit by default, providing comfortable viewing during nighttime use.
Eye Comfort Features
OnePlus has incorporated TÜV Rheinland Intelligent Eye Care 5.0 certification into the display system. The implementation includes an Eye Comfort Reminder function and a specialised Eye Comfort Mode for gaming applications. This mode adjusts colour saturation during extended gaming sessions to reduce eye strain whilst preserving visual quality.
Performance Architecture
Triple-Chip Configuration
The OnePlus 15 employs a triple-chip architecture that distributes processing tasks across dedicated components. The system centres around the Snapdragon 8 Elite Gen 5 Mobile Platform, which provides the primary processing power for the device.
Supporting the main processor is a dedicated touch response chip that enables 3200Hz touch sampling rates. This component handles input recognition and response, providing immediate feedback for user interactions. A standalone Wi-Fi chip manages network connectivity independently, maintaining stable connections in environments with multiple competing networks.
The system integrates with OxygenOS 16 and includes optimisations that enable simultaneous operation of multiple applications. Users can run two games concurrently or switch between resource-intensive applications without performance degradation.
Gaming-Specific Enhancements
For gaming applications, the OnePlus 15 maintains 120fps performance with zero frame drops during gameplay. The device includes a custom gyroscope with ±4000 DPS sensitivity, translating physical movements into precise in-game controls for competitive gaming scenarios.
Thermal Management System
360° Cryo-Velocity Cooling System
OnePlus has implemented a comprehensive thermal management solution called the 360° Cryo-Velocity Cooling System. The system incorporates a 5,731mm² 3D vapour chamber for core heat dissipation, managing thermal output from the primary processing components.
An aerospace-derived aerogel insulation layer prevents heat transfer to the device surface, maintaining comfortable handling temperatures during intensive use. The system includes a white graphite back cover that distributes heat uniformly across the device rear panel.
This cooling solution maintains consistent performance during extended gaming sessions and intensive multitasking scenarios, preventing thermal throttling that could impact user experience.
Battery Technology and Charging
Silicon NanoStack Battery
The OnePlus 15 features a 7300mAh Silicon NanoStack battery, representing the highest capacity battery used in any OnePlus smartphone. The battery utilises silicon anode technology with 15% silicon content, achieving improved energy density compared to traditional lithium-ion configurations.
Charging Capabilities
The device supports 120W SUPERVOOC wired charging for rapid battery replenishment. Wireless charging is available through 50W AIRVOOC technology, providing cable-free power delivery options.
OnePlus has included Bypass Charging functionality, which directs power directly to device components without charging the battery during use. This feature addresses gaming scenarios where continuous power delivery prevents heat generation and preserves battery longevity.
Battery Longevity and Environmental Performance
The battery system maintains over 80% of its original capacity after four years of regular use. Temperature resilience extends to -20°C operation, ensuring functionality in extreme cold conditions.
Durability and Protection
The OnePlus 15 achieves multiple protection ratings including IP66, IP68, IP69, and IP69K certifications. These ratings provide comprehensive protection against dust ingress, water immersion up to specified depths, and high-pressure water jets.
The IP69K rating specifically addresses high-temperature, high-pressure water exposure, providing protection beyond standard smartphone environmental sealing.
Software Integration
OxygenOS 16 provides the software foundation for the OnePlus 15’s hardware capabilities. The operating system includes optimisations that coordinate between the triple-chip architecture components, managing resource allocation and task distribution across dedicated processors.
System-level optimisations enable multitasking scenarios such as running multiple games simultaneously whilst maintaining performance stability. The software manages thermal profiles and performance scaling based on application requirements and device temperature.
Technical Specifications Summary
The OnePlus 15 combines several technical advances in a single device package. The 1.5K 165Hz LTPO display provides high refresh rate performance with adaptive refresh rate scaling. The triple-chip architecture distributes processing loads across specialised components rather than relying on a single processor for all functions.
The 7300mAh Silicon NanoStack battery represents a substantial capacity increase over previous OnePlus models, supported by 120W wired and 50W wireless charging capabilities. The 360° Cryo-Velocity Cooling System manages thermal output through multiple heat dissipation methods.
Environmental protection through IP66/68/69/69K ratings ensures device functionality across various conditions. The combination of these features targets users requiring sustained performance during intensive applications such as gaming, content creation, and multitasking workflows.
The OnePlus 15 launches globally on 13 November 2025, continuing OnePlus’s focus on performance-oriented smartphone development whilst addressing user requirements for extended battery life and sustained performance during demanding applications.
