Oppo F31 Specifications, Pros and Cons

Oppo F31 Specifications

Oppo launched the F31 on September 17, 2025, and it quickly made its way to stores later that month. Positioned in the mid-range segment, the phone aims to deliver a mix of performance, durability, and style. The F31 carries a solid IP68/IP69 rating for dust and water resistance and even meets MIL-STD-810H standards, a rare sight in this price range. Despite its tough build, it stays fairly slim at 8mm thick and weighs 185 grams, offering a comfortable grip. The design looks sleek, available in Midnight Blue, Bloom Red, and Cloud Green finishes. Up front, the Oppo F31 features a 6.57-inch AMOLED display with Full HD+ resolution (1080 × 2372 pixels) and a 120Hz refresh rate, making visuals smooth and vibrant. It supports 1 billion colors and reaches up to 1400 nits peak brightness, ensuring good outdoor visibility.

The display is protected by AGC DT-Star D+ glass, which adds a layer of durability. Watching videos or scrolling through apps feels fluid, and the stereo speakers enhance the media experience, though there’s no 3.5mm headphone jack, which might disappoint some. Under the hood, the phone runs on Android 15 with ColorOS 15, powered by the MediaTek Dimensity 6300 chipset (6nm). It comes with an octa-core CPU and Mali-G57 MC2 GPU, offering efficient performance for day-to-day tasks and moderate gaming. You can choose between 128GB or 256GB of UFS 2.2 storage, both paired with 8GB RAM, and there’s a microSD card slot for expansion. Connectivity options are modern, including 5G, dual-band Wi-Fi, and Bluetooth 5.4 with aptX HD support.

For photography, the Oppo F31 packs a 50MP main camera with PDAF and a secondary lens for depth assistance. It captures detailed shots in daylight, and features like HDR and panorama help add variety. Video recording goes up to 1080p at 120fps, which is decent for casual users. On the front, there’s a 16MP selfie camera that delivers good results with natural skin tones, also supporting 1080p video. Battery life is one of its biggest highlights. The massive 7000mAh cell easily lasts two days on light use. Charging is equally impressive, with 80W fast charging, 33W PPS, and 13.5W PD support, plus reverse wired charging for powering other devices. Overall, the Oppo F31 stands out as a dependable all-rounder under $259 (Rs 22,999 in India). It offers a bright AMOLED screen, strong battery backup, and a durable design, all packed in a stylish form. While it lacks NFC and a headphone jack, its combination of performance, build quality, and charging speed make it one of the most balanced phones in its segment.
