Oppo F31 Launch Confirmed: Durable Champion Phone Arrives Sept 15

Oppo F31 Series India Launch Date Confirmed for September 15

Oppo India has officially confirmed the launch date for its new F31 smartphone series, ending weeks of speculation. The new lineup, which includes the Oppo F31, F31 Pro, and F31 Pro+, will be unveiled in India on September 15, 2025, at 12 PM IST. The company has begun promoting the series with the tagline “Durable Champion,” strongly suggesting that build quality and battery life will be major highlights. This confirmed launch date is much earlier than some reports which incorrectly suggested a release later in the year.

A New Focus on Durability and Battery Life

Unlike many mid-range phones that focus only on camera pixels or processor speeds, Oppo is heavily marketing the F31 series’ toughness. Leaks suggest the phones will feature impressive IP66, IP68, and IP69 ratings. In simple terms, this means the device should be protected from powerful water jets (IP66), submersion in water up to 1.5 meters deep (IP68), and even high-pressure, high-temperature water sprays (IP69). This level of water resistance is extremely rare outside of specialized rugged phones and top-tier flagships from Apple or Samsung.

Furthermore, reports point to internal “Airbag” designs, where foam and silicone pads protect key components like the camera and battery from drops. The phones are also said to meet military-grade durability standards (MIL-STD-810H), making them capable of surviving harsh conditions. This focus on durability addresses a major concern for Indian consumers who want a phone that lasts for many years.

Massive 7,000mAh Battery Changes the Game

The second major headline feature for the entire Oppo F31 series is its battery capacity. All three models are expected to house a massive 7,000mAh battery. This is significantly larger than the typical 5,000mAh batteries found in most competing smartphones in 2025. For an average user, a battery this large could potentially offer two full days of use without needing to recharge. Oppo is combining this large battery with 80W SuperVOOC fast charging, ensuring that even this huge cell can be refilled quickly, likely reaching full charge in under an hour.

This combination of extreme durability and long battery life makes the F31 series a unique offering in the crowded Indian market. “Oppo is clearly targeting a practical pain point for consumers,” noted a technology analyst. “Users are tired of fragile phones and constant battery anxiety. If the pricing is right, this ‘Durable Champion’ approach could be very successful.”

Expected Specifications Across Three Models

While Oppo has confirmed the launch date and durability focus, specific processor and camera details remain based on strong leaks, set to be confirmed on September 15. The series is expected to cater to different price points with varied internal hardware for each model. The base Oppo F31 model will likely feature the MediaTek Dimensity 6300 processor, a capable chip for everyday tasks and casual gaming. The F31 Pro model is expected to get an upgrade to the MediaTek Dimensity 7300 for better performance.

The top-end model, the Oppo F31 Pro+, is rumored to use the powerful Snapdragon 7 Gen 3 processor, positioning it as a strong performer in the sub-₹35,000 segment. The primary camera on all models is expected to be a 50-megapixel sensor, with the Pro models likely featuring a higher resolution 32-megapixel selfie camera compared to a 16-megapixel sensor on the base version. All models are expected to feature large AMOLED displays with a fast 120Hz refresh rate.
