Design & Build Quality

The Oppo F31 Pro Plus features a large form factor with a 6.79-inch display and weighs 204 grams. As per official specifications, the back panel is made of polycarbonate, which helps keep weight manageable despite the massive battery.

The phone measures 7.9 mm in thickness, which is relatively slim considering its battery size. The in-hand feel is stable rather than compact, making it more suitable for users comfortable with big-screen devices. One standout aspect is its IP68, IP66, and IP69 water resistance, which is uncommon in this segment and adds practical durability.

Display Review

The smartphone sports a 6.79-inch AMOLED panel with FHD+ resolution (1280 × 2800 pixels) and a 120Hz refresh rate. With a peak brightness of 1600 nits, outdoor visibility is strong as per specifications.

The high 453 ppi pixel density ensures sharp text and media clarity. The punch-hole design and slim bezels contribute to an immersive viewing experience, making the device suitable for video consumption, social media browsing, and gaming. AGC Dragontrail protection adds basic scratch resistance.

Performance & Processor

Powered by the Qualcomm Snapdragon 7 Gen 3 (4nm) and Adreno 720 GPU, the Oppo F31 Pro Plus delivers stable mid-range performance.
