Durability Designed For Indian Conditions
The F31 series is engineered to withstand extreme heat up to 43 degrees Celsius, making it particularly suitable for outdoor workers and users in high-temperature zones. Each model is built with an AM04-grade aluminium alloy frame and AGC DT-Star D+ strengthened glass, offering enhanced drop protection and structural integrity.
The triple IP certifications ensure that the devices can survive dust storms, accidental submersion, and even high-pressure hot water exposure up to 80 degrees Celsius. These features make the F31 series one of the most rugged smartphone lineups in its segment.
Performance And Cooling Architecture
Under the hood, the F31 Pro+ is powered by Qualcomm’s Snapdragon 7 Gen 3, while the F31 Pro uses MediaTek’s Dimensity 7300 Energy, and the base F31 runs on Dimensity 6300. All models support up to 24GB RAM (including virtual RAM) and come with UFS 3.1 storage for faster data access.
To maintain performance under stress, OPPO has equipped the Pro+ with a 5,219mm² vapour chamber, while the Pro and base models feature slightly smaller chambers. These are supplemented with expanded graphite layers to prevent thermal throttling and ensure consistent frame rates during gaming, navigation, and multitasking.
Display And Camera Features
The F31 Pro+ sports a 6.8-inch flat AMOLED display with a 120Hz refresh rate, while the Pro and base models feature 6.57-inch AMOLED panels. All devices include under-display fingerprint sensors and support high-speed touch response.
Camera setups include a 50MP main sensor with optical image stabilization, a 2MP depth lens, and either a 16MP or 32MP front camera depending on the variant. AI tools such as AI Eraser 2.0, AI Unblur, and AI Clarity Enhancer elevate the photography experience, while underwater photography is supported up to 1.5 metres for 30 minutes.
Battery And Charging Efficiency
Each model houses a 7000mAh battery, supported by 80W SUPERVOOC Flash Charge. Users can expect a 58 percent charge in just 30 minutes and a full charge in just over an hour. Reverse charging and bypass charging features are included, allowing users to power other devices or maintain battery health during gaming.
Smart Productivity Tools
OPPO’s Dual-Engine Smoothness System combines the Trinity Engine with the Luminous Rendering Engine to deliver zero lag, latency, flicker, crash, mislaunch, or freeze. AI VoiceScribe, OPPO Docs with Gemini AI, and Call Assistant offer real-time transcription, translation, and document management—ideal for professionals on the move.
Mixing Intention With Innovation
With the F31 5G Series, OPPO India has redefined what mid-range smartphones can offer. By combining rugged durability with intelligent performance, the brand delivers a device family that’s not just built to last—but built to empower. Whether navigating heatwaves or juggling apps, the F31 series stands ready to meet the moment.
