Oppo F31 Pro Plus Specifications
The Oppo F31 Pro Plus, announced and released on September 16, 2025, comes across as a well-balanced mid-range phone with a focus on display quality and durability. It features a large 6.8-inch AMOLED panel with 1B colors, a smooth 120Hz refresh rate, and 1600-nit HBM brightness, making it bright and comfortable for outdoor use. The 1280 × 2800 resolution with ~453 ppi density delivers crisp visuals, while AGC DT-Star D+ protection adds some peace of mind. The phone also stands out with IP68/IP69 water and dust resistance and MIL-STD-810H compliance, giving it more durability than many phones in its price range.
Inside, the Oppo F31 Pro Plus runs Android 15 with ColorOS 15, powered by the Snapdragon 7 Gen 3 chipset, an octa-core CPU, and Adreno 720 GPU. This combination ensures smooth day-to-day performance, efficient multitasking, and respectable gaming capability. You get UFS 3.1 storage with either 8GB or 12GB RAM, and the device skips the microSD slot, relying on its 256GB internal storage. The stereo speakers, fast connectivity options including Wi-Fi 6, and precise positioning systems such as GPS L1+L5 and NavIC all improve the overall user experience. The phone also includes an under-display fingerprint scanner and an infrared port, although it lacks NFC and a 3.5mm headphone jack.
For cameras, the F31 Pro Plus carries a 50 MP main lens with OIS, supported by an auxiliary sensor and a color spectrum sensor for better color accuracy. It shoots 4K at 30fps with OIS and gyro-EIS for stable video performance. The 32 MP selfie camera delivers clean shots and supports 1080p video with EIS. Powering the device is a massive 7000 mAh Si/C Li-Ion battery, which pairs with 80W wired charging and multiple charging standards, plus 10W reverse wired charging, giving users strong battery endurance and flexible charging options. Available in Festival Pink, Himalayan White, and Gemstone Blue, the Oppo F31 Pro Plus is priced at around $364 (Rs 32,999 in India), making it a strong value option for users who want a big display, long battery life, and reliable performance without overspending.
