Oppo F31 Series India Launch Date
The official announcement came through Oppo’s social media channels, confirming that the Oppo F31 series launch event will take place on September 15, 2025. The launch follows the Oppo F29 series that arrived in March this year, meaning Oppo is refreshing its F-lineup fairly quickly.
Fans can expect the company to livestream the event on YouTube and other social platforms, giving a closer look at the design and features.
Oppo F31 Series Expected Price in India
While Oppo hasn’t officially revealed the pricing, leaks and reports suggest the following estimates:
Oppo F31 5G: Expected to be priced under ₹20,000, making it more affordable than the Oppo F29 5G, which launched at ₹23,999 for the base variant.
Oppo F31 Pro 5G: Likely to fall under ₹30,000, keeping it in line with the F29 Pro’s launch price of ₹29,999.
Oppo F31 Pro+ 5G: The new top-tier variant in the series, expected to be priced under ₹35,000.
With these rumored price points, Oppo seems to be targeting both budget-conscious and premium mid-range buyers.
Oppo F31 Series Expected Specifications
1. Durability
The biggest talking point of the Oppo F31 series is its durability. Reports suggest all three models will come with IP66 + IP68 + IP69 ratings for water and dust resistance. If true, this would make them among the most rugged smartphones in their price category.
2. Camera Setup
Rear Cameras: Each model is expected to feature a 50MP primary sensor paired with a 2MP depth sensor.
Front Camera: A 32MP selfie shooter is tipped to make its way across the lineup.
This setup suggests Oppo is focusing on a balance between durability and everyday photography, rather than introducing a heavy multi-camera array.
3. Battery
Another highlight is the rumored 7,000mAh battery, which would be one of the largest in this segment. If true, users can expect excellent endurance, possibly making the F31 series ideal for heavy users, gamers, and travelers.
4. Design & Colors
Each variant will carry a different rear design, giving them a distinct identity:
Oppo F31 5G: Square-shaped camera module with rounded edges, positioned at the top-left corner. Expected colors: Blue, Green, and Red.
Oppo F31 Pro 5G: Squircle-shaped camera module placed in the center. Expected colors: Gold and Grey.
Oppo F31 Pro+ 5G: Circular rear camera unit in the middle. Expected colors: Blue, Pink, and White.
What to Expect From the Oppo F31 Series
Oppo’s F-series has always been about a balance of design, innovation, and affordability. With the F31 series, the company appears to be focusing on:
Enhanced durability with multiple IP certifications.
Massive battery capacity for long-lasting usage.
Stylish and distinctive designs for each variant.
Competitive pricing that undercuts previous F-series models.
Given these expected features, the Oppo F31 lineup could attract both students and working professionals looking for a reliable, stylish mid-range device.
Final Thoughts
The Oppo F31 series is shaping up to be one of the most interesting mid-range smartphone launches of 2025. With the launch date confirmed for September 15, we won’t have to wait long to see how Oppo delivers on its promise of “durable champions.”
If the leaked specs and pricing turn out to be true, the series could give tough competition to brands like Samsung, OnePlus, iQOO, and Realme in the same price bracket.
