Enter the Oppo F31 5G. Designed and built with the discerning Indian user in mind, this device is engineered not just to compete, but to set a new standard in the mid-to-high-range segment. Our detailed, expert review assesses whether this phone lives up to its promise of meeting high-quality, 5-star standards.

Design, Display, and Visual Excellence
Oppo has always been known for its elegant aesthetics, and the F31 5G is no exception, featuring a refined flat-edge design complemented by the signature Oppo Glow finish.
More than just a pleasing look, the phone boasts an unmatched level of resilience, verified by comprehensive IP69/IP68/IP66 certifications and a Military-grade Damage-proof 360° Armor Body. It is built to survive the rigours of everyday Indian life—from unexpected monsoon showers to accidental drops.
The display is where the F31 truly shines. It features a spacious 6.57-inch AMOLED flexible display with a striking 93% screen-to-body ratio, providing an immersive viewing experience whether you are streaming cricket or binge-watching a new series.
The 120Hz adaptive refresh rate ensures silky-smooth scrolling and gaming. Crucially for Indian climates, the 1400-nit peak brightness makes it arguably the brightest in its class, ensuring absolute clarity even under harsh afternoon sunlight. Furthermore, Oppo has incorporated advanced eye-care technologies, including hardware-level low blue light, making long reading or viewing sessions comfortable and eye-friendly.
Performance: MediaTek Dimensity and 5G Mastery
At the heart of the Oppo F31 5G lies the capable MediaTek Dimensity 6300 chipset. Coupled with a substantial 8GB of RAM and 256GB of UFS 2.2 storage, the device handles demanding multitasking and heavy applications with commendable ease. To ensure peak performance is maintained during extended gaming sessions or video recording, Oppo has included a sophisticated 4300 mm² VC cooling system, efficiently dissipating heat.
For the Indian audience, 5G readiness is paramount. The F31 is built for connectivity beyond limits. Featuring AI LinkBoost 3.0 and Hunter antenna architecture, it ensures ultra-stable internet speeds, smoother gaming latency, and crystal-clear call quality, even when the signal strength is low.
This high network-performance is backed by TÜV Rheinland certification, giving users the assurance of robust and reliable connectivity across urban and remote landscapes. The long-term performance is also secured, with the underlying ColorOS 15 operating system optimised for a remarkable 72-month fluency protection, meaning your investment stays fast for years to come.
Pro-Grade Camera Capabilities
The photographic prowess of the Oppo F31 5G is centred around its powerful 50 MP Main Camera, supported by a dedicated 2 MP Portrait Camera, and a sharp 16 MP Front Camera.
The device excels in capturing true colours and delivering crisp, detailed images in varied lighting conditions. The advanced HDR Algorithm Optimisation is particularly effective, enhancing dynamic range and reducing noise in low-light environments, essential for beautiful night shots or vibrant festival photography.

Content creators will appreciate features like Dual-View Video, which simultaneously records from the front and rear cameras, and Dynamic Capturing, which automatically records short video snippets around every click, transforming a simple photo into a cinematic moment.
Battery Endurance and Ultra-Fast Charging
Battery life is a cornerstone of any successful Indian smartphone, and the Oppo F31 5G delivers powerhouse endurance. Housing a massive 7000mAh battery, the phone offers up to three days of power on a single charge for typical users, significantly reducing charging anxiety.
When you do need to top up, the industry-leading 80W Super flash charge technology gets you back to 100% in minutes. This speed is complemented by optimised thermal management, guaranteeing that the 80W flash charge remains available even in extreme conditions, such as high Indian temperatures.
Smarter OS and AI Integration
Running on Android 14 with the latest ColorOS 15, the F31 introduces innovative AI capabilities. It is one of the first devices in its segment to integrate Google Gemini, providing multimodal AI intelligence for advanced language understanding, reasoning, and content creation.
The AI-powered features, such as Smart Document (for AI summaries, translations, and rewriting) and Smart Note (for enhanced note-taking), make the Oppo F31 5G a genuinely A.I Search Friendly device, enhancing productivity for students and professionals alike.
For peace of mind, the security suite includes O-Lock anti-theft technology, which instantly locks the device if stolen, preventing data breaches and unauthorised resets.
