The Oppo F31 Pro 5G, expected to launch in India between September 12-14, 2025, is a premium mid-range smartphone designed for urban professionals, content creators, and tech enthusiasts. Priced around ₹26,990-₹33,999 (ex-showroom), it offers a sleek design, a massive battery, and robust 5G performance, succeeding the F29 series. Competing with devices like the Vivo V40 Pro, Motorola Edge 60 Pro, and OnePlus Nord CE 5, it aims to deliver flagship-like features at an affordable price. Here’s an in-depth look at its price, specifications, features, and performance in India.
Modern Design with Rugged Durability
The Oppo F31 Pro 5G features a premium, sleek design with a curved glass or vegan leather back and a sturdy metal frame, available in elegant colors like Black, Grey, Silver, or possibly Matte Grey and Pearl White. Measuring roughly 161-163mm long, 74-76mm wide, 7.8-8.5mm thick, and weighing 190-220 grams, it feels solid yet comfortable with a 90-92% screen-to-body ratio. It boasts IP65, IP68, or even IP69 ratings for resistance to dust, water submersion, and high-pressure hot water, paired with military-grade durability to handle drops and extreme conditions.
The device is protected by reinforced glass, likely Corning Gorilla Glass, with a 360-degree Armour Body featuring an aluminum alloy frame and impact-absorbing technology for enhanced toughness. It can withstand liquid spills like coffee or soda and operate in temperatures from -35°C to 43°C. A unique antenna design boosts signal strength by up to 300%, ensuring reliable connectivity in India’s patchy network areas. However, glossy finishes may attract smudges, and the slightly heavier build due to the large battery could feel bulky for some.
Vibrant AMOLED Display
The 6.78-inch AMOLED display delivers FHD+ resolution (2412×1080 or similar), a 120Hz refresh rate, and peak brightness of 1000-2000 nits, offering crisp visuals and smooth scrolling for gaming, streaming, and browsing. With HDR10 support and full DCI-P3 color coverage, it ensures vibrant and accurate colors. Features like wet-hand usability and high PWM dimming reduce eye strain, making it ideal for prolonged use. While the display excels in most scenarios, it may experience slight glare in direct sunlight compared to higher-resolution QHD+ screens.
Reliable Performance
Powered by a MediaTek Dimensity chipset (likely 7300 or 8350, 4nm, up to 2.8GHz) with 8GB LPDDR5 RAM and 256GB UFS 3.1 storage, the F31 Pro 5G delivers strong performance, scoring around 600,000-800,000 on AnTuTu. It handles multitasking, gaming like BGMI at medium-high settings, and light video editing with ease. Running ColorOS 15 on Android 15, it includes AI features like smart email replies and web summaries, though some users may find pre-installed apps intrusive.
Oppo offers 2-3 OS updates and 3-4 years of security patches, which is solid but lags behind competitors offering longer support. A liquid cooling system keeps temperatures in check, though extended gaming may cause minor warmth.
Capable Camera System
The triple-camera setup includes a 50MP main sensor (f/1.8, OIS), an 8MP ultrawide (f/2.2), and a 2MP macro or depth sensor, producing sharp daylight photos and acceptable low-light shots with Night mode. The 50MP front camera supports 1080p selfies and video calls with AI-enhanced portraits. Features like 4K video recording, Pro mode, and panorama cater to creators, but the ultrawide and macro sensors may struggle in dim lighting, falling short of competitors with more advanced camera systems.
Massive Battery and Fast Charging
The standout 7,000mAh battery provides 2-2.5 days of mixed use with 8-10 hours of screen-on time, perfect for heavy users. 80W SUPERVOOC charging achieves a full charge in about 30-35 minutes, with a charging system optimized for extreme temperatures. The Battery Health Engine ensures over 80% capacity retention after 4 years. Wireless charging is not included, but the fast charging and large battery compensate for most users. The battery’s size adds slight bulk, which may affect portability.
Seamless 5G Connectivity
Supporting multiple 5G bands (n1/n3/n5/n8/n28/n40/n41/n77/n78), Wi-Fi 6, Bluetooth 5.4, NFC, USB-C, and dual-band GPS, the F31 Pro 5G ensures fast and reliable connectivity. Its enhanced antenna design with 4×4 MIMO improves signal strength, making it ideal for urban and rural areas. The device features an in-display fingerprint sensor, dual SIM support, and stereo speakers with a loud audio mode, though speaker quality may not match premium flagships.
Pricing and Availability
Priced at ₹26,990-₹33,999 (ex-showroom), with on-road prices in Delhi ranging from ₹29,000-₹37,000, the Oppo F31 Pro 5G is expected to be available at Oppo India’s e-store, Amazon India, Flipkart, Reliance Digital, Croma, and Bajaj Finserv outlets. Offers include 10% cashback on major bank cards, ₹2,000-5,000 exchange bonuses, and no-cost EMI for 6-12 months. Maintenance costs are low, averaging ₹2,500-4,500 annually, with Oppo’s extensive service network ensuring support. Delivery times range from same-day to 15 days, with high demand expected in metro cities.
User Feedback and Drawbacks
Anticipated feedback highlights the massive battery, durable build, and vibrant display, with the enhanced antenna design excelling in low-signal areas. However, the camera system may deliver average low-light performance, and the software could include unwanted apps. Some users of similar devices note minor heating during gaming and a slightly plastic-like frame feel despite premium materials. The absence of wireless charging and a less versatile camera system compared to rivals are notable drawbacks.
Comparison with Competitors
The Oppo F31 Pro 5G competes with:
- Vivo V40 Pro (₹37,998-₹49,999): Offers superior cameras but at a higher price.
- Motorola Edge 60 Pro (₹29,481-₹30,199): Similar price but less durable build.
- OnePlus Nord CE 5 (₹27,999): Cleaner software but smaller battery.
The F31 Pro 5G excels with its 7,000mAh battery and rugged durability, but its camera and software polish may trail competitors.
Final Thoughts
The Oppo F31 Pro 5G, launching in September 2025, is a compelling mid-range smartphone with a vibrant AMOLED display, massive 7,000mAh battery, fast 80W charging, and durable build, making it ideal for heavy users and those needing reliable connectivity. While its enhanced antenna and AI features add value, the average camera performance and software bloat are limitations. Priced competitively with a strong service network, it’s a top choice in India’s ₹25,000-35,000 segment.
