Oppo has confirmed that its latest F31 series will debut in India on September 15 at 12 pm IST. The lineup comprises three models—the Oppo F31 5G, Oppo F31 Pro 5G and Oppo F31 Pro+ 5G—each carrying the “Durable Champion” badge. With a strong emphasis on ruggedness, battery life and competitive pricing, Oppo aims to shake up the mid-range 5G segment.
Durability Takes Centre Stage
In marketing materials, Oppo highlights IP66, IP68 and IP69 dust- and water-resistance ratings across the entire F31 family. The robust build promises protection against high-pressure water jets and total dust ingress, raising the bar for sub-Rs. 30,000 handsets. Reinforced glass on both front and back and an internally strengthened chassis are expected to bolster drop resistance.
Distinctive Design Language
While all three models share a toughened frame, each variant sports a unique camera module:
- Oppo F31 5G: top-left square-shaped unit with rounded corners, finishes in Blue, Green and Red
- Oppo F31 Pro 5G: centred squire shaped design, offered in Gold and Grey colours
- Oppo F31 Pro+ 5G: circular centre-mounted array, available in Blue, Pink and White colours
By blending vibrant hues with premium textures, Oppo caters to style-conscious users who value both aesthetics and resilience.
Display and Performance
All three phones boast an AMOLED panel with a fluid 120Hz refresh rate, ensuring smooth animations and responsive touch interactions. Screen sizes vary slightly:
- F31 5G and F31 Pro 5G: 6.57-inch, Full HD+ AMOLED
- F31 Pro+ 5G: 6.79-inch, Full HD+ AMOLED
Under the hood, the standard F31 runs on the MediaTek Dimensity 6300 chipset, paired with 8GB RAM and 128 GB storage. The F31 Pro upgrades to the Dimensity 7300 Energy, while the Pro+ model jumps to Qualcomm’s Snapdragon 7 Gen 3, with storage options up to 256GB. All variants include expandable storage via microSD.
Photography
Photography remains consistent across the series with a 50 MP primary sensor and a 2 MP depth-mapping camera at the rear. Selfie shooters differ slightly:
- F31 5G: 16 MP front camera
- F31 Pro 5G and Pro+ 5G: 32 MP front camera
Software enhancements such as AI scene detection, night mode and portrait lighting are expected to carry over from Oppo’s flagship Find series, promising sharp images in diverse conditions.
Battery and Charging
Standout battery life is a key selling point, with a massive 7000 mAh cell powering each handset. Users can expect up to two days of moderate usage on a single charge. Fast-charging support varies:
- Oppo F31 5G: 80W SuperVOOC wired charging
- F31 Pro 5G and Pro+ 5G: likely 100W charging, pending official confirmation
Reverse charging and ultra-power-saving modes will help extend runtime when outlets are scarce.
Software and Connectivity
The F31 series is tipped to ship with Android 15-based ColorOS 15, featuring new privacy controls, smooth multitasking and customizable always-on displays. Connectivity highlights include:
- Dual-SIM 5G (SA/NSA)
- Wi-Fi 6, Bluetooth 5.3
- USB-C port, 3.5 mm headphone jack
- Side-mounted fingerprint sensor and face unlock
These features ensure seamless daily use and broad carrier compatibility across India.
Pricing and Availability
Early leaks position the F31 series at aggressive price points below its predecessors:
- Oppo F31 5G: Rs. 20,000–Rs. 25,000
- Oppo F31 Pro 5G: Rs. 25,000–Rs. 30,000
- Oppo F31 Pro+ 5G: around Rs. 35,000
Sales will kick off on September 15 via Flipkart, Oppo’s online store and select brick-and-mortar outlets. Bundled launch offers may include exchange discounts and no-cost EMI plans.
Competitive Outlook
In a crowded mid-range market populated by the likes of Xiaomi’s Redmi Note series, OnePlus’s Nord series and Realme’s Number series, Oppo’s focus on durability and battery endurance could provide a clear differentiator. While competitors push high-refresh displays and punchy price tags, the F31 trio stakes its claim on long-term reliability and consistent performance.
As the launch event approaches, Oppo’s F31 5G series promises to deliver a balanced mix of rugged design, extended battery life and capable hardware—all at wallet-friendly prices. We’ll bring you complete hands-on impressions and final verdicts once the devices go official on September 15.
