Oppo, one of India’s leading smartphone makers, has officially confirmed the launch of the much-anticipated F31 Series. Slated for release on September 15, 2025, at 12 PM IST, the upcoming lineup includes three new 5G smartphones Oppo F31 5G, Oppo F31 Pro 5G, and Oppo F31 Pro+ 5G. Positioned in the mid-range category, the F31 Series is being marketed as a “Durable Champion”, underscoring Oppo’s focus on strength, reliability, and next-generation features for everyday users.
The F31 Series serves as a direct successor to the Oppo F29 lineup that launched earlier this year, offering a major upgrade in terms of performance, design, battery life, camera innovations, and water resistance. With a combination of long-lasting power, enhanced durability standards, and premium imaging capabilities, the new devices are tailored for demanding consumers looking for a balance between style and robust functionality.
Breakthrough Durability
Standards A defining highlight of the Oppo F31 Series is its triple-layer durability protection, which is expected to set new benchmarks in the mid-range smartphone segment. Each of the three handsets will come with IP66, IP68, and IP69 ratings, significantly enhancing their ability to withstand water and dust damage.
The IP66 certification provides consistent protection against powerful water jets; IP68 ensures long-term resistance against water immersion; and IP69 allows devices to sustain high-pressure water flow and extreme outdoor conditions. Together, these standards make the F31 Series one of the strongest waterproof and dustproof lineups ever introduced in this category.
This approach matches Oppo’s “Durable Champion” branding message, reassuring consumers who increasingly expect smartphones to survive challenging real-world usage whether it be accidental spills, heavy rains, or dusty environments.
Power That Lasts Longer Another key element of the F31 Series is its unprecedented 7,000mAh battery capacity, which is significantly higher than most devices in today’s market, even in the flagship range. This powerful battery pack is designed to provide extended usage without frequent recharging – delivering peace of mind for heavy users, frequent travellers, gamers, and content creators.
Industry insiders suggest that with optimized
AI-driven enhancements, the F31 smartphones could easily deliver two full days of moderate-to-heavy usage on a single charge. Oppo is also set to equip the handsets with fast charging technology, allowing users to quickly power up even such a large battery in a reasonable time frame.
With growing consumer concerns about battery performance, Oppo has targeted this fundamental need with a long-lasting solution that stands out from the competition.
Imaging Capabilities Tailored for Everyday Creativity All three devices in the Oppo F31 Series are confirmed to feature a 50MP primary sensor in the rear camera system. This high-resolution lens will deliver sharp, detailed, and vibrant imagery across a variety of lighting conditions. Accompanying the main camera, Oppo is expected to integrate a 2MP depth sensor, designed to enhance portrait photography with clear subject separation and natural-looking bokeh effects.
For selfie enthusiasts and video calling users, the smartphones will be equipped with a powerful 32MP front camera, strengthening the line’s reputation for front-facing imaging excellence. This aligns with Oppo’s tradition of appealing to younger customers and social media creators who prioritize high-quality selfies and smooth video performance.
The combination of an advanced 50MP rear shooter and a 32MP selfie lens positions the Oppo F31 Series as one of the most balanced camera experiences in the segment.
Pricing Strategy and Market
Positioning According to industry reports and early leaks, Oppo plans to launch the three F31 models at competitive price points designed to challenge rivals in the mid-range 5G market:
- Oppo F31 5G is expected to be priced under ₹20,000.
- Oppo F31 Pro 5G may arrive at under ₹30,000.
- Oppo F31 Pro+ 5G could be available for under ₹35,000.
These price points mirror the accessibility of the earlier Oppo F29 Pro 5G, which launched at ₹29,999, while adding the new Pro+ variant for additional performance and features not previously offered in the F29 lineup.
Oppo’s strategy appears to focus on widening the appeal of the F-series by offering multiple options in varying configurations. This ensures customers across different price brackets will find an F31 model suited to their needs.
The affordable entry point below ₹20,000 for the base variant also makes Oppo F31 5G an attractive value proposition for students, first-time 5G buyers, and young professionals.
Mid-Range Smartphones with Premium Value By integrating flagship-level durability, a massive battery, and strong imaging capabilities into a mid-range design, Oppo is positioning the F31 Series as the ideal everyday smartphone for the Indian market. The devices are expected to compete with rival brands that currently dominate the 5G mid-tier category, especially those emphasizing gaming performance, camera features, and battery reliability.
The launch is also strategically timed ahead of the festive season, a period when smartphone demand in India traditionally peaks. Oppo’s refreshed product portfolio suggests the company wants to capture consumer interest with innovation and durability at competitive price tags.
Official Launch and Availability
The Oppo F31 Series will be unveiled on September 15, 2025, at 12 PM IST through a live-streamed event broadcast on Oppo’s official social media platforms. Product availability and detailed specifications are expected to be announced following the unveiling, with sales likely to begin shortly after launch.
