The OPPO F31 Pro+ 5G stands out in the competitive mid-range smartphone market in India. As displays grow larger, batteries get bigger, cameras promise remarkable features, and performance metrics are tossed around, this phone opts for endurance, refinement, and daily dependability.
After using the OPPO F31 Pro+ 5G as a primary device for over a week, it becomes evident that it does not showcase a singular standout feature but instead presents a variety of thoughtful elements that create a surprisingly enjoyable user experience. Nonetheless, some missing features raise questions about value in 2025.
Highlights
- 1 Design and Display: Clean, Calm, and Confident
Design and Display: Clean, Calm, and Confident
The first noticeable aspect is the how the OPPO F31 Pro+ 5G feels in hand, epitomising a restrained design. Its flat matte back resists fingerprints and reflections, with the Gemstone Blue finish offering a subtle sheen under light without being overly flashy. At a thickness of 7.7mm and weighing 195g, it may not be the lightest device, but the weight is well balanced, giving it a solid presence.
The front showcases a generous 6.8-inch AMOLED display featuring a 120Hz adaptive refresh rate. This panel excels within its category. Colours appear vibrant yet realistic due to complete DCI-P3 coverage, and brightness remains strong even in sunny conditions. Support for HDR10 enhances visuals on streaming platforms like Netflix and YouTube, while high-frequency PWM dimming is beneficial for nighttime screen use.
The slim bezels and small punch-hole design minimize distractions, and the stereo speaker system, utilising the earpiece as a secondary driver, performs surprisingly well for casual viewing.
Durability That Actually Matters
OPPO demonstrates a clear intent for the F31 Pro+ 5G to endure daily challenges. The device boasts IP66, IP68, and IP69 ratings, which are uncommon at its price point, and the MIL-STD-810H certification offers additional peace of mind. This phone is ideal for long commutes, rainy outings, or dusty workplaces.
Performance: Dependable, Not Ambitious
The Snapdragon 7 Gen 3 processor is a reliable choice. It ensures efficiency, stability, and predictability, although it lags behind newer competitors. Daily performance is consistently smooth, with quick app loading times and effortless multitasking courtesy of 12GB of RAM, supported by an effective vapour chamber for thermal management.
Gaming capabilities are adequate but not exhilarating. Games like BGMI and Call of Duty Mobile run smoothly at high settings, and Genshin Impact is playable with sensible adjustments. While this device isn’t meant for extreme gaming benchmarks, it remains reliable.
Software: Polished and Packed with AI
ColorOS 15 layered over Android 15 presents a mature interface. Animations are seamless, and layouts are tidy, enhanced by the Flux Theme system that provides useful personalisation options.
OPPO’s AI features offer a mix of innovation; however, the standout tools include AI Unblur and Reflection Remover, which perform well on less-than-perfect photos, while AI Summary simplifies lengthy texts and call logs. The promise of two Android updates and three years of security updates feels standard rather than generous, although still acceptable.
While some pre-installed applications can be a nuisance, most are removable. The inclusion of an IR blaster provides a delightful, unexpected utility.
Cameras: Good, but Playing It Safe
The 50MP main camera provides trustworthy results in daylight, capturing clear detail and a consistent dynamic range. The colours appear natural, and auto HDR does an admirable job of managing highlights. Low-light capabilities are decent with OIS, though they do not match the very best available options.
The lack of an ultra-wide camera stands out as a significant drawback. A 2MP depth sensor feels outdated, particularly in this price range. While portrait images are adequate, versatility is limited.
The 32MP front camera delivers reliable performance, producing clear selfies with accurate skin tones. Video recording reaches a maximum of 4K at 30fps with effective stabilisation, although the limitation of portrait video recording at 720p feels rather restrictive.
Audio and Multimedia: Quietly Competent
Stereo speakers offer clear and balanced sound, even at high volumes, without distortion, and the spatial separation is commendable for a smartphone. Widevine L1 ensures HD streaming, and HDR support performs reliably across popular platforms.
The absence of a headphone jack or FM radio is no longer surprising in this category.
Connectivity and Biometrics
5G capabilities are broad and dependable, while Wi-Fi 6 shows strong performance, and call quality is excellent. OPPO’s AI LinkBoost appears to enhance connectivity in crowded or weak signal environments, particularly indoors.
The in-display fingerprint sensor operates quickly and accurately, and face unlock performs reliably in well-lit conditions. The options for customising fingerprint animations and quick launch shortcuts add thoughtful details.
Battery Life: The Real Headline
The 7,000mAh battery is undoubtedly the highlight of the OPPO F31 Pro+ 5G. Users can expect up to two full days of usage easily, and even those who use their phone heavily will find it hard to drain the battery in a single day. Screen-on time typically hovered around six hours with 120Hz enabled.
The 80W SuperVOOC charging facilitates a full battery in approximately one hour, making the substantial capacity much less daunting. Assurances regarding battery health are reassuring, particularly for those intending to use their device for several years.
Final Verdict: A Phone That Knows Its Priorities
The OPPO F31 Pro+ 5G does not aim to be the most thrilling phone in its segment, but it emphasises battery life, display quality, durability, and a smooth everyday experience. This thoughtful restraint enhances its appeal.
However, the lack of an ultra-wide camera and reliance on an older chipset make it difficult to recommend unreservedly at its price point. There are faster options and more versatile camera systems available for a similar cost.
If endurance, a large and visually appealing screen, and a consistently reliable phone matter most, the OPPO F31 Pro+ 5G makes a compelling case. Those prioritising performance metrics or camera versatility may wish to explore other alternatives.
