Network

This smartphone supports a wide range of connections, starting with the latest 5G technology which ensures ultra-fast connectivity and downloads. For areas where 5G isn't available, it falls back on robust 4G LTE networks with a comprehensive band coverage (1, 3, 5, 8, 19, 28, 38, 40, 41, 42, 48) that ensures a steady and reliable internet experience. Backward compatibility ensures that the phone can also connect using GSM and HSPA networks.

Launch and Availability

The Oppo F31 Pro+ was officially announced on September 16, 2025, and became instantly available on the same day. This immediate availability highlights Oppo's commitment to ensuring customers worldwide can quickly access their latest technology developments.

Design and Build

The dimensions of the Oppo F31 Pro+ stand at 163.1 x 77.6 x 7.7 mm, making it a sleek handheld device that weighs between 195 to 204 grams, depending on the configuration. Its build supports dual Nano-SIM functionality, adding flexibility for the user to manage two contact numbers or networks simultaneously. The design is not only modern but also practical, supporting a comfortable grip and a premium feel.

Display Features

The smartphone boasts a stunning 6.8-inch AMOLED display capable of rendering 1 billion colors, offering vibrant and crisp visuals with a 120Hz refresh rate and a peak brightness of 1600 nits. Packed with a resolution of 1280 x 2800 pixels, the screen yields an impressive pixel density of about 453 ppi, ensuring sharpness that appeals to mobile enthusiasts and gamers alike. The AGC DT-Star D+ protection ensures durability against scratches and other display damages.

Operating System and Performance

Running on Android 15 coupled with ColorOS 15, the Oppo F31 Pro+ delivers a seamless and intuitive user experience with several customization options. Under the hood, it is powered by the Qualcomm Snapdragon 7 Gen 3 chipset which is constructed on a 4nm process, offering improved efficiency and superior power management. The octa-core CPU comprises 1x2.63 GHz Cortex-A715, 3x2.4 GHz Cortex-A715, and 4x1.8 GHz Cortex-A510, delivering robust performance whether for gaming, productivity, or multimedia consumption. The integrated Adreno 720 GPU ensures high-quality graphics rendering, enhancing gaming and video streaming experiences.

Memory and Storage

The device arrives with two RAM configurations: 8GB and 12GB, paired respectively with 256GB of internal storage to cater to varying user needs. Given its substantial storage capacity, there's no inclusion of a memory card slot, but the existing internal memory is ample for numerous apps, high-definition content, and extensive data storage.

Camera Capabilities

On the camera front, the Oppo F31 Pro+ does not disappoint. The dual-primary camera system includes a 50 MP wide lens with f/1.8 aperture, PDAF and OIS for stabilized, sharp images even in low-light conditions. The additional 2 MP depth sensor enhances portrait shots with more detailed background-foreground separation. It offers video recording options such as 4K at 30fps and several frame rates for 1080p recording, aided by gyro-EIS for smoother video capture. The 32 MP front-facing camera, with a wide-angle lens and panorama support, delivers high-quality selfies and effortless video calling.

Audio and Connectivity

The absence of a 3.5mm jack shifts music-lovers to depend on the impressive stereo speaker setup or Bluetooth headphones. However, the device compensates by delivering aptX HD sound via Bluetooth 5.2. For further connectivity, it includes dual-band Wi-Fi (802.11 a/b/g/n/ac/6), USB Type-C 2.0 with OTG, and an infrared port for remote control purposes. Though NFC support is not provided, the other connection features suffice for efficient device interactions.

Equipped with an under-display optical fingerprint sensor, the Oppo F31 Pro+ guarantees swift and secure device access. Other sensors include an accelerometer, a gyro for motion detection, a proximity sensor, a compass, enhancing the overall functionality. The device comes in three appealing colors: Festival Pink, Himalayan White, and Gemstone Blue, giving consumers aesthetic choices. With a SAR level legally compliant at 1.16 W/kg for the head, safety standards in terms of radiation emissions are well-maintained.

Battery Performance

The phone packs a massive Si/C Li-Ion 7000 mAh battery, supporting extensive usage throughout the day without frequent recharges. Charging capabilities are bolstered by an 80W wired fast-charge system with additional 13.5W Power Delivery, 44W UFCS, and 33W PPS options. Impressively, the device achieves a 42% battery charge within 20 minutes, ensuring minimal downtime. Also, 10W reverse wired charging allows the phone to act as a power bank for other devices.
