Oppo has officially launched its latest premium mid-range smartphone, the Oppo F31 Pro+, on September 16, 2025. The device is now available for purchase and combines a stylish design with powerful hardware, an AMOLED display, and an industry-leading 7000mAh battery.
The Oppo F31 Pro+ strikes a balance between elegance and toughness. It measures 163.1 x 77.6 x 7.7 mm (or 7.9 mm) and weighs either 195 g or 204 g, depending on the variant. The phone supports dual Nano-SIM cards and comes with IP68/IP69 certification, offering dust-tight protection and resistance against water immersion up to 1.5 meters for 30 minutes. It also withstands high-pressure water jets. With MIL-STD-810H compliance, it adds an extra layer of durability, though not guaranteed for extreme rugged use.
At the front, the device features a 6.8-inch AMOLED display with support for 1 billion colors, HDR visuals, and a smooth 120Hz refresh rate. It achieves 1600 nits HBM brightness for outdoor readability and offers a crisp resolution of 1280 x 2800 pixels (~453 ppi). The display is protected by AGC DT-Star D+ glass, enhancing resistance against scratches and accidental drops.
The smartphone runs on Android 15 with ColorOS 15, providing a feature-rich and customizable software experience. Under the hood, it is powered by the Qualcomm Snapdragon 7 Gen 3 (4nm) chipset with Adreno 720 GPU, ensuring efficient performance for daily tasks, gaming, and multitasking. The octa-core CPU includes high-performance Cortex-A715 cores and energy-efficient Cortex-A510 cores for balanced performance.
The Oppo F31 Pro+ is available in two storage options:
With UFS 3.1 storage technology, users can expect fast read/write speeds for apps, files, and games. However, there is no microSD card slot, so storage expansion is not possible.
On the rear, the F31 Pro+ houses a dual-camera setup:
The rear camera supports features like HDR, panorama, color spectrum sensor, and LED flash, and it can record 4K videos at 30fps and 1080p at up to 120fps with gyro-EIS and OIS stabilization.
For selfies, the device offers a 32 MP wide front camera with panorama mode and 1080p video recording with gyro-EIS, making it ideal for content creators and video calls.
The Oppo F31 Pro+ delivers immersive sound with stereo speakers but skips the 3.5mm headphone jack. Connectivity options include Wi-Fi 6, Bluetooth 5.2 (with aptX HD), GPS, GLONASS, BDS, Galileo, QZSS, and NavIC support. It also features an infrared port for remote control functionality. However, NFC and FM radio are not included.
One of the most impressive aspects of the F31 Pro+ is its 7000mAh silicon-carbon Li-Ion battery, a massive capacity rarely seen in smartphones today. It supports multiple charging technologies:
Oppo claims the phone can charge up to 42% in just 20 minutes. Additionally, it supports 10W reverse wired charging, allowing it to double as a power bank for other devices.
The device includes an under-display optical fingerprint sensor along with essential sensors such as accelerometer, gyro, proximity, and compass.
The Oppo F31 Pro+ comes in three premium finishes: Festival Pink, Himalayan White, and Gemstone Blue.
