Display & Performance
The Oppo F31 uses a bright AMOLED panel with a 120Hz refresh rate and a flat profile — smooth UI scrolling and snappy animations are visible in daily use. Pixel density and color reproduction are solid for the segment, and brightness is adequate for outdoor visibility. The device is targeted at everyday users rather than power gamers; the MediaTek Dimensity 6300 (on the F31 base) and its memory configuration deliver smooth social apps, streaming and light gaming, but you shouldn't expect flagship-level sustained frame rates.
Camera: what to expect
The rear setup centers around a 50MP main sensor with optical image stabilization (OIS), which helps capture sharper handheld photos and smoother video. In daylight the main camera produces well-exposed images with good detail; low-light shots benefit from OIS but will show noise compared with higher-end sensors. There’s a small secondary lens (2MP) that acts as a helper; the ultra-wide/tele options are limited on the base F31. Video is stable thanks to OIS and ColorOS camera optimizations.
Battery life & charging
Battery is the headline: a 7,000mAh battery delivers multi-day use for moderate users and 1.5–2 days for heavy users. Oppo pairs this with 80W SuperVOOC charging; the company claims fast top-ups (58% in ~30 minutes and full charge in ~60+ minutes for some variants). Reverse charging and bypass charging for longer gaming sessions are also included in the feature set. This combination makes the F31 ideal for commuters, field workers and users who dislike daily charging.
Software & Updates
The phone runs ColorOS 15 based on Android 15 and ships with standard Oppo feature sets (AI camera features, battery management and security). Oppo has committed to a couple of OS updates and several years of security support for the series adequate for mid-range buyers but not aggressive by flagship standards.
Real-world tests & impressions
- Daily use: All-day fluidity for browsing, social apps and streaming.
- Gaming: Playable on medium settings; thermal throttling kept in check thanks to Oppo’s optimizations, but high-frame-rate gaming will push the chipset.
- Photography: Great stabilized handheld shots in daylight; low-light is decent but not class-leading.
- Battery: Multi-day endurance is real; charging speed is convenient for quick top-ups.
Price & should you buy?
The Oppo F31 positions itself as a battery-first mid-range phone with a balanced camera system. In India the base 8+128GB starts at ~₹22,999 with availability from Sept 27, 2025 — that positioning makes it a strong option for users who prefer battery life over flagship-level camera versatility. If you want more camera flexibility or top-tier gaming chops, consider the Pro or Pro+ models or alternatives from competing brands.
