Built for Durability and Outdoor Use
One of the major highlights of the F31 Series is its focus on durability. Oppo has equipped all three smartphones with a 360° Armour Body, built using AM04-grade aluminum alloy frames and AGC DT-Star D+ strengthened glass. This robust construction is complemented by triple IP certifications — IP66, IP68, and IP69 — making the devices dustproof, water-resistant, and capable of withstanding high-pressure hot water exposure up to 80°C.
This rugged design means the F31 Series is well-suited for users working in challenging environments — from scorching summers to dusty roads — ensuring that the device remains reliable throughout the day.

Thermal Management and Performance
Oppo has gone the extra mile in managing heat dissipation and sustained performance. The F31 Pro+ 5G is equipped with a massive 5,219 mm² vapor chamber, while the Pro and base models feature slightly smaller 4,363 mm² and 4,300 mm² vapor chambers, respectively. These are paired with multiple layers of expanded graphite to keep internal temperatures under control during prolonged use, gaming sessions, or heavy multitasking.
On the software side, Oppo introduces its Dual-Engine Smoothness System, combining the Trinity Engine and Luminous Rendering Engine to maintain snappy performance, reduce app reloads, and optimize RAM usage. This allows users to switch between apps, maps, and messaging services without worrying about crashes or lag.
Hardware and Chipset Options
Each device in the Oppo F31 Series comes with a 7,000mAh battery — one of the largest in its class — promising uninterrupted use for an entire day or more. Charging is equally impressive, thanks to 80W SUPERVOOC fast charging, which can juice the phone up to 58% in just 30 minutes and achieve a full charge in just over an hour. The series also supports reverse charging to power other devices and a bypass charging mode to reduce battery wear during gaming.
Performance across the series is powered by different chipsets:
-
Oppo F31 Pro+ 5G: Qualcomm Snapdragon 7 Gen 3
-
Oppo F31 Pro 5G: MediaTek Dimensity 7300 Energy
-
Oppo F31 5G: MediaTek Dimensity 6300
All three models support up to 24GB of RAM (including virtual RAM expansion) and come with UFS 3.1 storage for faster app loading and data transfers.
Display and Design
The Oppo F31 Pro+ 5G sports a 6.8-inch flat AMOLED display with a 120Hz refresh rate, ensuring smooth scrolling and a vibrant viewing experience. The F31 Pro and F31 feature slightly smaller 6.57-inch AMOLED panels, still offering vivid colors and deep contrasts. All devices have under-display fingerprint sensors for seamless authentication.
Color options vary by model:
-
F31 Pro+ – Gemstone Blue, Festival Pink
-
F31 Pro – Desert Gold, Space Grey
-
F31 – Midnight Blue
Camera and AI Features
The F31 Series places a strong emphasis on camera quality, packing a 50MP primary sensor with Optical Image Stabilization (OIS) across all models. Oppo has integrated AI-powered tools like AI Eraser 2.0 for removing unwanted objects from images, AI Unblur for sharpening motion photos, and AI Clarity Enhancer for boosting detail in challenging lighting conditions.
For productivity, the series introduces AI VoiceScribe, which transcribes audio notes and conversations in real-time, and OPPO Docs with Gemini AI, which assists with translations, document editing, and quick summaries — ideal for students and working professionals.
Software Experience
The F31 Series runs on the latest version of ColorOS, optimized to work seamlessly with the Trinity Engine. Users can expect better multitasking, reduced app reloads, and a cleaner interface. With Oppo’s extended software support promise, buyers can expect long-term updates for both system stability and security patches.
