OPPO’s F-series is built for style-first buyers who still want smooth performance and great battery life. The OPPO F31 follows that brief with a slim, light body, a vibrant 120Hz AMOLED display, fast charging, and cameras tuned for bright, social-ready photos. It targets students and everyday users who want a modern-looking 5G phone that feels premium without a premium price.

Design & Build
The F31 leans into a sleek, fashion-forward aesthetic: flat sides, a thin profile, and a matte back that shrugs off fingerprints. Camera rings are minimalist and sit nearly flush, keeping the phone pocket-friendly. Weight distribution is balanced for one-handed texting, and the frame’s gentle edges make long scrolling or reading sessions comfortable. Colorways skew tasteful and modern—smart enough for the office, fun enough for campus.
Display & Audio
A 120Hz FHD+ AMOLED panel is the showpiece. Scrolling is buttery, animations feel immediate, and HDR content looks punchy with deep blacks and lively color. Peak brightness helps maps and chats stay clear in strong sunlight, while touch sampling responds snappily in games and fast UIs. The single bottom speaker is fine for reels and podcasts; pair TWS earbuds for fuller stereo separation when binge-watching or gaming.
Performance
An efficient 6nm octa-core 5G chipset powers the F31 with a focus on real-world smoothness. The 8GB RAM option (with virtual RAM where available) keeps apps alive in the background as you hop between camera, chat, and browser tabs. Everyday tasks—UPI payments, food delivery, short-form video, and navigation—run without fuss. Popular games are best at balanced/medium graphics for steady frames and cooler temps; the phone prioritizes stability over showy benchmarks, which is the right call in this segment.
Cameras
The 50MP main camera is tuned for bright, shareable photos in daylight. Colors have pleasing pop without looking cartoonish, and autofocus locks quickly for point-and-shoot moments. Portrait mode cuts subjects cleanly in good light, while the auxiliary sensor helps with depth or close-ups—use it outdoors for best results. The front camera (around 16MP, market dependent) delivers crisp selfies and clean video calls; dial back beauty effects for natural skin tones. In low light, Night mode and a steady hand yield social-ready shots, though very dark scenes will still show some noise, typical for this class.
Battery & Charging
A 5,000mAh battery anchors the experience. With mixed 5G data, reels, maps, and messaging, most users comfortably finish a full day; lighter users can push longer. Fast wired charging is a genuine quality-of-life win: a short coffee break top-up adds meaningful hours of use, and thermal management keeps charging steady. If you travel or hotspot occasionally, the F31’s efficiency plus big cell provides headroom when you need it.
Software & Extras
ColorOS on a recent Android build brings a polished, customizable UI: smart sidebar, flexible theming, granular privacy controls, and handy utilities like screen translate and app cloner. Bloat is minimal and can be trimmed. Depending on variant, you get an in-display or side-mounted fingerprint reader—both quick and consistent—plus face unlock for convenience. Call quality on major Indian networks is clear, and dual-SIM support with a dedicated or hybrid microSD slot (model dependent) makes juggling work and personal lines easy.
Verdict
The OPPO F31 nails the style-plus-substance brief: a slick 120Hz AMOLED screen, dependable 5G performance, fast charging, and cameras that deliver bright, social-ready photos—wrapped in a slim, modern design. If your checklist reads “premium look, smooth display, strong battery, and fuss-free daily speed,” the F31 belongs on your shortlist. Gamers chasing ultra graphics may prefer pricier silicon, but for most buyers the F31 offers an attractive, well-balanced package at the right price.
