The Oppo F31 Series is gearing up for its official debut, and leaks suggest the lineup will feature two models – the standard F31 and the more advanced Oppo F31 Pro. Both devices are positioned in the upper midrange segment and are rumored to bring major upgrades in battery life, durability, and overall design.
According to reliable leaks shared by tipster @passionategeekz on X (formerly Twitter), the Oppo F31 Series will pack an impressive 7000mAh battery, a significant leap from the 6000mAh unit in the F29 and the 6500mAh in the F29 Pro. While exact charging speeds remain under wraps, industry watchers expect the new phones to match or even surpass the previous generation’s performance.
Durability is another highlight of this upcoming lineup. Oppo is reportedly reintroducing its “Next-Level Durability” feature, which includes an IP69 rating and a reinforced 360° Armor Body design. This build not only promises resistance against accidental drops and liquid exposure but also enhances network stability. The F29 series carried an MIL-STD-810H military-grade certification, so the new F31 lineup could bring equal or improved protection standards.
As per Oppo’s release pattern, the F-series refresh usually happens every six months. With the last launch taking place in March, the latest reports indicate that the Oppo F31 Series may arrive in September. This timing aligns with recent leaks, adding weight to the expected launch window.
