The OnePlus 9 Pro is a premium flagship smartphone that continues OnePlus’s tradition of delivering high-performance devices with top-tier specifications. Launched in March 2021, this device stands out with its Hasselblad-tuned camera system, 120Hz LTPO AMOLED display, and ultra-fast charging capabilities. Designed to compete with giants like the Samsung Galaxy S21 Ultra and iPhone 12 Pro Max, the OnePlus 9 Pro brings a refined user experience with OxygenOS (based on Android 11, upgradable to Android 14) and powerful hardware under the hood.
One of the key highlights of this device is its collaboration with Hasselblad, a legendary camera brand, ensuring enhanced color accuracy and professional-grade photography. Additionally, the Snapdragon 888 chipset, 12GB RAM, and 65W Warp Charge make it a performance beast. However, the battery life has been a point of debate, with some users reporting shorter-than-expected endurance despite the 4500mAh capacity. In this in-depth review, we’ll explore the OnePlus 9 Pro’s specifications, performance benchmarks, camera capabilities, and real-world usability to help you decide if it’s still a worthy flagship in 2025.

Display & Design
The OnePlus 9 Pro boasts a 6.7-inch Fluid AMOLED display with a QHD+ resolution (3216 x 1440 pixels) and a 120Hz adaptive refresh rate. Thanks to LTPO technology, the screen dynamically adjusts between 1Hz and 120Hz, optimizing battery efficiency without compromising smoothness. The 1300-nit peak brightness ensures excellent outdoor visibility, while HDR10+ support enhances color depth and contrast for an immersive viewing experience.
In terms of design, the phone features a sleek glass-and-metal construction with IP68 water and dust resistance, making it durable for daily use. The curved edges provide a premium feel, though some users report accidental touches. The Hasselblad-branded quad-camera setup is neatly arranged, and the alert slider—a signature OnePlus feature—remains a handy addition for quick sound profile changes.
Performance & Battery Life
Powered by the Qualcomm Snapdragon 888 chipset and up to 12GB LPDDR5 RAM, the OnePlus 9 Pro delivers blazing-fast performance for gaming, multitasking, and heavy workloads. The Adreno 660 GPU handles graphics-intensive games effortlessly, while UFS 3.1 storage ensures quick app launches and file transfers.
However, the battery life is a mixed bag. The 4500mAh battery supports 65W wired charging (0-100% in 29 minutes) and 50W wireless charging (full charge in 43 minutes). While these speeds are industry-leading, the actual screen-on time (SOT) ranges between 4-6 hours due to the power-hungry 120Hz QHD+ display and Snapdragon 888’s heat generation. Some users report overheating issues during prolonged gaming sessions, which can throttle performance .
Camera: Hasselblad Partnership
The OnePlus 9 Pro’s camera system is its biggest upgrade, thanks to the Hasselblad collaboration. The quad-camera setup includes:
- 48MP Sony IMX789 (main, OIS) – Excellent dynamic range and low-light performance.
- 50MP Sony IMX766 (ultrawide) – One of the best ultrawide sensors, with minimal distortion.
- 8MP telephoto (3.3x optical zoom) – Decent for portraits but struggles in low light.
- 2MP monochrome sensor – Enhances black-and-white photography.
The Hasselblad color calibration provides natural tones, though some users find Samsung and Apple’s processing more consistent. The 8K video recording and 4K@120fps capabilities are impressive, but the lack of optical zoom in videos is a notable drawback .
Software & Longevity
The OnePlus 9 Pro launched with OxygenOS 11 (Android 11) and is upgradable to Android 14. While OxygenOS is praised for its clean, bloat-free experience, recent updates have merged with ColorOS, leading to mixed reactions from long-time fans. OnePlus promises 3 years of OS updates and 4 years of security patches, ensuring long-term usability .
