Oppo F31 Pro+ Review: Endurance Monster with Quirky Design, Big Battery & Tough Build
Introduction: The Unconventional Contender
In the relentlessly competitive mid-to-high-end smartphone market, a device needs more than just a passing feature set to stand out. It needs a defining characteristic, a personality. Enter the Oppo F31 Pro+, a phone that doesn't just flirt with unconventional design and exceptional battery life—it fully commits. Marketed heavily on its unrivalled durability and an almost mythical 7,000mAh battery, the F31 Pro+ positions itself as the "Endurance Monster" of its class. Priced around the Rs. 32,999 mark (for the base variant), it faces stiff competition from rivals offering arguably better processors or more versatile camera setups. Our comprehensive review dives deep to answer the essential question for every prospective buyer: Does the sheer longevity and rugged build justify the compromises in other areas? This detailed breakdown covers everything from its eye-catching, albeit quirky, aesthetics to its day-to-day performance, camera capabilities, and value proposition. Get ready for the full scoop on this intriguing Oppo 5G mobile phone.
1. Design, Build Quality, and the 'Quirky' Aesthetic
The F31 Pro+ immediately makes a statement. While many flagships chase subtle refinement, this phone opts for a striking, almost unapologetic aesthetic.
The Look: Our review unit, the Gemstone Blue variant, is a conversation starter. It features a dual-tone or prismatic finish on the back that catches the light in a dazzling, unexpected way, lending it the "quirky design" label. It’s certainly a departure from the monotonous matte slabs dominating the segment. The camera module, a large, centrally-placed circle, sits flush with a gentle ramp, contributing to its distinct look. However, the glossy flat edges and the matte, yet fingerprint-prone, back panel, mean you'll be wiping it down often, a slight irritant for the fastidious user.
The Build Monster: The true story of the design is its durability. Oppo has equipped the F31 Pro+ with a 360-degree Armour Body and an aerospace-grade aluminium alloy frame, making it one of the toughest mid-rangers available. This isn't just marketing fluff; the phone boasts multiple high-level IP ratings: IP66, IP68, and even the industry-leading IP69. These ratings ensure resistance to dust, high-pressure, high-temperature water jets, and even submergence. For users who work outdoors, are frequently clumsy, or live in demanding environments, the F31 Pro+ offers peace of mind that its rivals simply can’t match. It’s a durable smartphone built to last.
In-Hand Feel: Despite its huge 7,000mAh battery, the phone manages a respectable thickness of 7.7mm (Gemstone Blue variant) and weighs around 195g, which is impressive. However, the broad, boxy design makes one-handed use challenging, especially for those with smaller hands. The company thoughtfully includes a protective cover and a pre-fitted screen guard, emphasizing the device’s focus on long-term user value.
2. Display Excellence: A Visual Treat
The display is where the F31 Pro+ solidifies its multimedia credentials.
Specifications: It sports a large 6.8-inch Full HD+(2800×1280p) AMOLED display with a buttery-smooth 120Hz refresh rate. The screen boasts a high pixel density of 453 PPI and supports HDR10+ certification.
Viewing Experience: This is an excellent panel for content consumption. Colors are vivid and punchy, blacks are deep and inky, and the high refresh rate makes scrolling and animations incredibly fluid. Crucially, the display reaches a peak brightness of up to 1600 nits, ensuring excellent visibility even under direct, harsh sunlight, which is a major win for an outdoor-centric, durable phone. The minimal bezels and central punch-hole maximize the screen real estate for an immersive viewing experience, cementing its position as a top-tier Oppo AMOLED phone for movie lovers and casual gamers.
3. Performance and Software: The Efficiency Trade-off
Under the hood, the F31 Pro+ makes an interesting, potentially polarizing choice for its price segment.
Chipset: The device is powered by the QualcommSnapdragon7 Gen 3 chipset, coupled with up to 12GB of LPDDR4X RAM and 256GB of UFS 3.1 storage. While a capable and highly power-efficient 4nm processor, it is perceived as slightly underwhelming when compared to some rivals in the same price bracket, which might offer a last-gen flagship chip.
Benchmarks and Real-World Use:
Day-to-Day: In daily use—multitasking, browsing social media, watching videos, and handling productivity apps—the Snapdragon 7 Gen 3 performs flawlessly. The operating system, Android 15-based ColorOS 15.0, is fluid, responsive, and handles transitions with ease, aided by the large RAM configurations.
Gaming: For casual and moderate gaming, the phone maintains excellent thermal efficiency, thanks to its large 5,219mm2 SuperCool VC system. Demanding games like BGMI run smoothly on high settings. The only caveat for competitive, hardcore gamers is the frame rate limit, as the phone holds a 60FPS cap, while a few rivals are now pushing 100FPS or more in this price range.
Software and AI Features: ColorOS 15.0 comes with a plethora of Gen AI-powered features like AI VoiceScribe, AI Editor 2.0 (AI Perfect Shot, AI Eraser 2.0), and AI Call Assistant. While powerful, the software experience is marred by a noticeable amount of pre-installed third-party apps, or 'bloatware', which users may need to manually uninstall to achieve a cleaner user interface.
4. Endurance Monster: Battery Life and Charging
This is, without a doubt, the F31 Pro+’s defining, non-negotiable strength.
The Mammoth Battery: The smartphone packs a colossal 7,000mAh battery. This is significantly larger than the average battery size in this segment (), delivering truly exceptional longevity.
Real-World Endurance Test: In our rigorous testing, which included hours of streaming, social media use, and an hour of gaming, the F31 Pro+ comfortably lasted a full day and a half of heavy usage. For light to moderate users, two full days on a single charge is easily achievable. This makes it a perfect long-lasting battery phone and a true endurance monster.
Charging Speed: To manage this massive cell, Oppo includes its proprietary 80W SuperVOOC Flash Charge support. This fast-charging technology is impressively efficient, taking the battery from 0% to 100% in just about 70 minutes. The combination of incredible longevity and rapid charging is a major win for power users and those constantly on the go.
5. Camera Review and Comparisons: Where It Stumbles
The camera system is the one area where the F31 Pro+ clearly takes a back seat to its battery and durability focus.
Hardware Setup: The phone features a dual-camera setup on the rear:
50MP Main Sensor with f/1.8 aperture and OIS (Optical Image Stabilization).
2MP Monochrome Sensor (more of a token inclusion).
The front houses a 32MP Selfie Camera.
Missing Versatility: A glaring omission at this price point is the lack of an Ultrawide Lens or a Telephoto Lens. This immediately limits the phone's photographic versatility compared to rivals.
Image Quality:
Daylight: The 50MP primary sensor is competent. Daylight shots are generally sharp, detailed, and have good dynamic range. Colors are often well-saturated, but sometimes lack the 'pop' or vibrance seen in competitors’ processing.
Low-Light: The performance is 'par for the course.' With ambient light, the phone captures decent, usable images. In extremely dark scenes, however, it struggles to maintain detail and can produce softer images compared to rivals.
Portraits & Selfies: Portrait shots are acceptable, but edge detection can be hit-or-miss. Selfies from the 32MP front camera are good in well-lit conditions, offering high detail, but Oppo’s processing tends to over-smooth facial textures.
Verdict: While the camera is decent for casual social media sharing, it is undoubtedly the F31 Pro+’s weakest link, especially when compared to photography-focused devices in the same price segment.
6. Comparisons and Value Proposition (SEO Keyword Integration)
The Oppo F31 Pro+ is a specialist, not a generalist. Its value proposition is built on two pillars: unbeatable battery endurance and rugged durability. If you are an outdoor worker, a heavy user who often forgets to charge, or someone who prioritizes a phone that can withstand drops and the elements, this device offers unique features that its rivals cannot touch. It’s the perfect durable mid-range phone for the modern adventurer. However, if your primary usage is high-frame-rate mobile gaming or professional-grade mobile photography, its competitors, which offer a better processor or a more comprehensive camera setup, will provide a better fit. You are essentially making a choice: endurance and toughness over raw processing power or camera versatility.
7. Final Review and Conclusion
The Oppo F31 Pro+ is an impressive device that succeeds brilliantly in its defined niche. It delivers an outstanding multimedia experience with its huge, bright 120Hz AMOLED display and offers unprecedented peace of mind with its military-grade durability and multiple IP ratings (IP66/IP68/IP69). The massive 7,000mAh battery, combined with 80W fast charging, transforms it into a true mobile endurance champion, virtually eliminating battery anxiety.
Pros:
Phenomenal Battery Life (7,000mAh) and 80W Fast Charging.
Industry-Leading Durability (IP66, IP68, IP69) and 360-degree Armour Body.
Excellent with high brightness.
Efficient thermal management and stable performance for daily use.
Cons:
Lacks Versatile Cameras (No Ultrawide/Telephoto lens).
The Snapdragon 7 Gen 3 chipset is not the best in its price segment for peak gaming performance.
ColorOS 15.0 has noticeable pre-installed bloatware.
The 'quirky' design is a fingerprint magnet and may be too bulky for some.
Verdict:
If you are a consumer looking for a reliable daily driver that you can absolutely depend on for two-day battery life and a tough, durable build, the Oppo F31 Pro+ is a resounding Buy. It is the ultimate long battery life smartphone for users who value resilience and longevity above all else. For those who prioritize a flagship-level processor or a multi-lens camera array for professional photography, better-specced alternatives exist. The F31 Pro+ is a unique, powerful solution for a specific need, and in that, it truly excels.
