The Oppo F31 Pro+ is a feature-rich smartphone released on September 16, 2025, representing Oppo’s effort to deliver premium performance, an elegant design, and enduring battery life in a device built for modern users. Running Android 15 with ColorOS 15, it combines refined software with reliable hardware, making it suitable for entertainment, productivity, photography, and everyday communication. With an emphasis on durability, display quality, and long-lasting battery performance, the F31 Pro+ positions itself as a balanced mid-premium smartphone designed to meet the demands of diverse users.
Design and Build Quality
The Oppo F31 Pro+ features a sleek and lightweight construction with a thickness of just 7.7 mm and a weight of either 195 g or 204 g depending on the variant. Despite its slim profile, the phone offers exceptional durability with IP68 and IP69 ratings that protect it against dust, water immersion up to 1.5 meters for 30 minutes, and even high-pressure water jets. It also follows the MIL-STD-810H standard, giving it resistance to drops and environmental stress, although not guaranteeing extreme ruggedness. The dual Nano-SIM support enhances convenience for users who require multiple networks in one device.
Display Experience
The device sports a large 6.8-inch AMOLED panel with support for 1 billion colors and a smooth 120Hz refresh rate, offering an immersive viewing experience with vibrant visuals and fluid animations. The 1600-nit high brightness mode ensures excellent outdoor visibility even under direct sunlight. With a resolution of 1280 x 2800 pixels and a pixel density of 453 ppi, the screen delivers crisp, detailed content. The AGC DT-Star D+ protection enhances durability, making the display resistant to scratches and accidental bumps.
Performance
and Software
Powered by the Qualcomm Snapdragon 7 Gen 3 chipset built on a 4 nm architecture, the Oppo F31 Pro+ offers an efficient and responsive performance profile suited for daily multitasking, gaming, and sustained productivity. The octa-core CPU setup consists of high-performance Cortex-A715 cores and power-efficient Cortex-A510 cores, balanced to deliver speed while maintaining battery efficiency. The Adreno 720 GPU handles gaming and graphical applications with ease. Android 15 combined with ColorOS 15 brings refined animations, advanced customization, improved security features, and smoother overall user experience.
Storage and Memory
The phone offers two memory options—256GB paired with either 8GB or 12GB of RAM—ensuring fast operations and extensive background app handling. Since the device uses UFS 3.1 storage, users benefit from swift read–write speeds, quick file transfers, and snappy app loading times. There is no card slot, meaning storage is fixed but sufficient for power users, media consumers, and gamers.
Camera
Performance
The Oppo F31 Pro+ carries a dual-camera setup on the rear, featuring a 50MP wide primary sensor with optical image stabilization and phase detection autofocus. The camera is supported by an auxiliary lens and a color spectrum sensor to enhance color accuracy and dynamic range. It delivers stable footage and detailed clarity in various lighting situations, with support for 4K recording at 30fps and multiple 1080p frame rate options including 30, 60, and 120fps through gyro-EIS and OIS stabilization. On the front, a 32MP wide camera offers sharp selfies with natural color tones and smooth 1080p video recording, ensuring clear visual communication.
Audio and Connectivity
The Oppo F31 Pro+ includes stereo speakers that provide balanced and immersive audio, although the device does not incorporate a 3.5mm headphone jack. Wireless connectivity remains robust with Wi-Fi 6 support, efficient Bluetooth 5.2 that includes aptX HD for enhanced audio transmission, and advanced multi-band positioning systems such as GPS L1+L5, Galileo E1+E5a, GLONASS, NavIC L5, and more. The presence of an infrared port adds versatility for remote-control features, while the USB Type-C 2.0 port supports OTG devices. NFC is absent, which may be a drawback for users relying on contactless payments.
Battery
and Charging
One of the strongest aspects of the Oppo F31 Pro+ is its massive 7000 mAh Silicon–Carbon Lithium battery that provides extended usage spanning a full day and beyond, even for power users. The phone supports 80W wired charging along with additional protocols such as 13.5W PD, 44W UFCS, and 33W PPS, ensuring compatibility across different chargers. It is capable of reaching 42% in just 20 minutes, offering quick top-ups for users on the go. Additionally, the device supports 10W reverse wired charging, allowing it to serve as a power source for smaller gadgets like earbuds or smartwatches.
Conclusion
The Oppo F31 Pro+ stands out as a powerful and dependable smartphone crafted for users who prioritize long battery life, display quality, durability, and smooth performance. Its combination of a large 7000 mAh battery, Snapdragon 7 Gen 3 chipset, refined ColorOS 15 interface, and vibrant AMOLED display makes it a strong contender in its segment. While the absence of NFC and a headphone jack may limit certain preferences, the overall offering—from its reliable camera system to its rugged build and fast charging capabilities—positions the Oppo F31 Pro+ as a well-rounded device suitable for everyday use, multimedia consumption, and long-term reliability.
