Design and Display
OPPO keeps the F-series design language sleek: slim sides, tasteful camera island, and a matte back that resists smudges. The AMOLED-class display is the star—punchy colors, deep contrast, and smooth scrolling thanks to up to 120Hz refresh. Reading, gaming menus, and social feeds feel fluid, while an adaptive refresh helps conserve power when you’re just browsing or messaging. An eye-comfort mode and DC-dimming-style tuning reduce strain during late-night sessions.
Performance and Software
Under the hood, a 5G-capable 6nm chipset prioritizes consistent day-to-day speed over headline bragging rights. App launches are quick, multitasking between Chrome, WhatsApp, and Instagram feels responsive, and RAM expansion helps keep more apps in memory. ColorOS adds smart touches—flexible windowing, privacy controls, and granular notification management—without weighing the phone down. The overall experience is snappy and polished, even after weeks of use.
Cameras tuned for social
The 50MP main camera uses pixel-binning to pull in more light, producing detailed daylight shots and well-balanced dynamic range. OPPO’s AI scene detection reliably picks color and contrast boosts for food, sky, and greenery. Portrait mode offers pleasing edge separation and adjustable bokeh, while Night mode leans on multi-frame processing to tame noise and preserve highlights. The selfie camera serves sharp reels and video calls, with HDR keeping backgrounds from blowing out. Video features like Ultra Steady (variant-dependent) and beauty filters are handy for creators who want great-looking clips straight from the phone.
Battery and Charging
A ~5000mAh battery is the F31’s quiet superpower. With mixed use—chatting, short videos, maps, and music—you can comfortably clear a full day and often dip into a second. When you do need a top-up, fast charging over USB-C gets you back on the move quickly; actual wattage and inbox charger availability vary by region, so check your retail bundle. Battery health features help reduce long-term wear.
Connectivity and Extras
Dual-SIM 5G keeps you future-proofed on Indian networks, while Wi-Fi ac and Bluetooth 5.x ensure stable accessories and streaming. Game tools can boost performance, block calls/notifications, and record gameplay. With an in-display/side fingerprint reader plus face unlock, getting into your phone is instant and secure. Always-On Display widgets for time, music, and notifications add a premium feel.
Verdict
The OPPO F31 hits the modern mid-range sweet spot: a vivid high-refresh display, reliable 5G performance, a versatile 50MP camera, and battery life that makes you forget the charger. If you value style, smoothness, and creator-friendly features without paying flagship money, the F31 is an easy recommendation for everyday users and aspiring content creators alike.
