Key features
The Pro and F31 feature MediaTek’s Dimensity 7300 Energy and Dimensity 6300 chipsets, respectively, while the F31 Pro+ is powered by Qualcomm’s Snapdragon 7 Gen 3. All support UFS 3.1 storage and up to 24GB of RAM (12GB real + 12GB virtual). The phones, which run ColorOS 15, come with a one-click performance rejuvenation tool, enhanced touch responsiveness, and intelligent pre-loading.
With an aerospace-grade AM04 aluminum alloy frame that is 10% stronger than its predecessor, the F31 series has a 360° armor body design. The triple IP certifications (IP66, IP68, and IP69) make the devices resistant to dust, immersion, and even high-pressure water jets at temperatures as high as 80°C. The AGC DT-Star D+ glass provides further screen protection. According to Oppo, the phones are resistant to rain, greasy fingers, and even 18 common liquids like tea and washing water.
Heat control is one of the main priorities. While the Pro and basic F31 utilize smaller but still sturdy cooling systems, the F31 Pro+ has a 5,219 mm² vapour chamber. With TÜV Rheinland’s 72-Month Fluency Certification, Oppo’s Dual-Engine Smoothness System—which includes the Trinity Engine and Luminous Rendering Engine—maintains applications’ responsiveness, speeds up installation, and guarantees six years of reliable performance.
AI tools and cameras
While the Pro+ and Pro add a 32MP selfie camera (16MP on the base model), all three versions include a 50MP OIS primary sensor. The goal of AI products like Reflection Remover, AI Unblur, and AI Eraser 2.0 is to improve regular photography. AI VoiceScribe for transcription and AI Call Assistant with real-time translation in nine Indian languages increase productivity.
The series promises a 58% charge in 30 minutes with its 7,000mAh battery and 80W SUPERVOOC rapid charging. Additionally supported are bypass and reverse charging.
