Design and Build Quality
The OnePlus Ace 5 Ultra follows the company’s modern smartphone design language, combining a large flat display with a clean rear panel and a prominent camera module.
Rather than focusing on an extravagant exterior, the handset prioritises a practical design suited to everyday use and extended gaming sessions.
Colour Options
The phone is available in three colour options:
- Breeze Blue
- Burning Titanium
- Phantom Black
Colour names may differ slightly when translated from Chinese retail listings. Buyers importing the device should check the exact colour and model code before ordering.
The flat display is particularly useful for gaming because it reduces accidental touches along curved screen edges. The phone also incorporates an in-display optical fingerprint sensor for biometric authentication.
Display: 6.83-Inch 1.5K AMOLED With 144Hz Refresh Rate
One of the main selling points of the OnePlus Ace 5 Ultra is its large AMOLED display.
The phone features a 6.83-inch flat panel with a resolution of 1272 × 2800 pixels. This 1.5K resolution offers a balance between sharp image quality and processing efficiency.
144Hz Refresh Rate
The screen supports a refresh rate of up to 144Hz. A higher refresh rate allows supported content to display more frames per second, creating smoother scrolling, animations and gameplay.
For mobile gaming, the difference is most noticeable in titles that support high-frame-rate modes. However, a 144Hz display does not mean every game will run at 144 frames per second. Actual performance depends on the game, settings, software support and thermal conditions.
The display also supports HDR10+, HDR Vivid and Dolby Vision. OnePlus lists a peak brightness of up to 1,400 nits under specified conditions.
Eye Comfort and Touch Response
The screen includes high-frequency PWM dimming specified at up to 3,840Hz to help manage display flicker at lower brightness levels. OnePlus also lists TÜV Rheinland Eye Protection 4.0 certification.
The combination of a large flat panel, high refresh rate and responsive touch input makes the display suitable for competitive games, racing titles and other fast-paced mobile experiences.
Performance: MediaTek Dimensity 9400+
The OnePlus Ace 5 Ultra is powered by the MediaTek Dimensity 9400+, a flagship-class mobile processor manufactured using a 3nm process.
The chipset is designed to deliver high CPU, GPU and artificial intelligence performance, positioning the Ace 5 Ultra as a serious option for demanding smartphone workloads.
CPU and GPU Architecture
The Dimensity 9400+ uses an all-big-core CPU architecture, combining high-performance Arm CPU cores with MediaTek’s flagship Immortalis GPU.
This design is intended to deliver strong performance in tasks such as:
- Running demanding Android games.
- Editing photos and videos on a smartphone.
- Multitasking between resource-intensive applications.
- Processing AI-powered features and computational photography.
- Handling high-resolution media playback.
Real-world performance will vary depending on the application, software version, temperature and power settings.
RAM and Storage Configurations
OnePlus offers several memory configurations to accommodate different user requirements.
| RAM | Internal storage | China launch price |
|---|---|---|
| 12GB | 256GB | CNY 2,499 (approximately $350) |
| 16GB | 256GB | CNY 2,799 (approximately $390) |
| 12GB | 512GB | CNY 2,999 (approximately $420) |
| 16GB | 512GB | CNY 3,299 (approximately $460) |
| 16GB | 1TB | CNY 3,799 (approximately $530) |
The phone uses LPDDR5X RAM and UFS 4.0 storage. These technologies provide high memory bandwidth and fast internal storage performance, helping with application loading, multitasking and transferring large files.
The 1TB option is particularly useful for people who install multiple large games, record substantial amounts of video or keep extensive offline media libraries.
Advertised storage is not entirely available for personal files because the operating system and pre-installed applications occupy some space.
Gaming Features and Thermal Management
Gaming is a major focus of the OnePlus Ace 5 Ultra. The combination of the Dimensity 9400+, 144Hz display, high-speed memory and dedicated thermal management makes it suitable for demanding mobile gaming.
Glacier Cooling System
OnePlus equips the Ace 5 Ultra with its Glacier cooling system, designed to help manage heat generated by the processor during intensive use.
Heat management matters because a smartphone operating at high power for an extended period can become warm. When temperatures rise, the processor may reduce its operating speed to protect the hardware.
An effective cooling system can help maintain more consistent performance during long gaming sessions, although it cannot eliminate thermal limitations entirely.
Actual gaming results depend on ambient temperature, graphics settings, the specific game and how long the device is used continuously.
High-Frame-Rate Gaming
The 144Hz display offers support for smoother gameplay in compatible titles. Competitive players may appreciate the combination of a fast screen and a powerful processor, especially in games where rapid movement and responsive controls are important.
Frame-rate support is determined by individual games and their optimisation for the device. A game restricted to 60fps will not automatically run at 144fps simply because the display supports that refresh rate.
Camera System: 50MP Main Camera and 8MP Ultrawide
Although the OnePlus Ace 5 Ultra focuses heavily on performance, it also includes a dual rear-camera system designed for everyday photography.
The rear cameras consist of a 50MP primary sensor with optical image stabilisation and an 8MP ultrawide camera. The front-facing camera has a 16MP resolution.
50MP Primary Camera With Optical Image Stabilisation
The 50MP main camera is the primary photography sensor. Optical image stabilisation (OIS) helps reduce the effects of small hand movements when capturing photos and recording video.
This can be particularly useful in lower-light conditions and when shooting handheld. The main camera is suited to everyday photography, including portraits, landscapes, food photography and general social-media content.
A 50MP specification does not by itself determine image quality. Sensor size, lens quality, image processing, lighting and camera software all influence the final result.
8MP Ultrawide Camera
The secondary 8MP ultrawide camera allows users to capture a wider field of view than the primary camera.
This is useful for group photos, architecture, travel photography and landscapes where fitting more of a scene into the frame is important.
However, the lower resolution means that fine details may not be as well preserved as they are with the main sensor, particularly in challenging lighting.
16MP Front Camera
The front-facing 16MP camera supports selfies, video calls and online meetings.
It should be suitable for routine social-media use, although users looking for advanced selfie photography or a dedicated telephoto camera may prefer a smartphone with a more comprehensive camera system.
Overall, the Ace 5 Ultra’s cameras are geared towards everyday versatility rather than competing directly with camera-focused flagship phones.
Battery and Charging: 6,700mAh With 100W SUPERVOOC
Battery capacity is another important feature of the OnePlus Ace 5 Ultra. The smartphone comes with a 6,700mAh battery and supports 100W wired SUPERVOOC charging.
6,700mAh Battery Capacity
A 6,700mAh battery provides a relatively large energy reserve for a smartphone, making the Ace 5 Ultra suitable for people who spend considerable time gaming, streaming video, browsing the internet or using social applications.
The large battery is particularly relevant for mobile gaming because high refresh rates, intensive graphics processing and sustained connectivity can all increase power consumption.
Battery life will depend on several factors, including:
- Screen brightness and refresh-rate settings.
- Mobile network signal strength.
- Gaming duration and graphics settings.
- Background applications and notifications.
- Ambient temperature and battery condition.
A large battery does not guarantee a fixed number of hours of use. Independent testing under consistent conditions is needed to compare endurance accurately with competing devices.
100W SUPERVOOC Fast Charging
The Ace 5 Ultra supports 100W wired SUPERVOOC charging, allowing compatible charging equipment to replenish the battery at a high power level.
Charging speed is affected by battery temperature, the remaining charge, the charger and cable used, and the phone’s charging-management system.
Peak charging power is not maintained throughout the entire charging cycle. The phone typically reduces charging power as the battery approaches full capacity to manage heat and battery safety.
Buyers importing the Chinese version should check the included charger, plug type and compatibility with their local electrical outlets.
Software and User Experience
The OnePlus Ace 5 Ultra launched in China running Android 15 with ColorOS 15.
ColorOS is Oppo’s Android-based software platform, and the Chinese Ace 5 Ultra uses this software rather than the OxygenOS interface typically associated with international OnePlus smartphones.
ColorOS 15 Features
ColorOS 15 offers a range of customisation and productivity features, including interface personalisation, multitasking tools, privacy controls and system-level performance management.
The software is designed to complement the phone’s powerful processor and high-refresh-rate screen.
However, buyers should distinguish between the Chinese-market software and the international OxygenOS experience. They are not necessarily identical in terms of pre-installed applications, supported services, available languages, updates and regional functionality.
What Importers Should Know
The Ace 5 Ultra was launched as a China-market device. Purchasing an imported Chinese model may involve additional considerations, such as:
- Google Mobile Services and Play Store availability.
- Android Auto and wearable-device compatibility.
- Notification behaviour and background application restrictions.
- Network-band compatibility with local carriers.
- Software update availability and language support.
The availability of individual features can depend on the software version and subsequent updates. Buyers should verify these details with the seller before purchasing.
Do not assume that installing a different launcher or changing system settings will convert the Chinese model into an officially supported international version.
