The Oppo F31 Pro+ emerges as a compelling mid-range contender, distinguished by its exceptional battery life and striking design. Priced around Rs 32,999 in India, this smartphone aims to deliver reliability and endurance, catering to users who prioritize longevity and a unique aesthetic.

Design and Build Quality

The Oppo F31 Pro+ immediately grabs attention with its unconventional design. The "Gemstone Blue" variant, in particular, features a dual-tone finish where the lower portion reflects a subtle bluish-purple hue when light strikes it at an angle. This shimmering effect extends to the circular camera module, creating a subtle, glowing ring. The device is also available in Himalayan White and Festival Pink.

While the visual charm is undeniable, the in-hand feel might not entirely translate to a premium experience. The glossy, flat edges and fiberglass build can be prone to fingerprints and smudges. However, the included case offers a secure grip and protects the phone's design.

Durability is a key focus, with the F31 Pro+ boasting MIL-STD-810H testing and IP66, IP68, and IP69 ratings for dust and water resistance. The Multi-Layer Airbag Cushioning system safeguards internal components from accidental drops. The phone feels broader, making one-handed use less comfortable. Despite housing a large battery, the phone remains relatively slim and lightweight, measuring 7.7mm thin and weighing 195g.

Display

The Oppo F31 Pro+ sports a 6.8-inch AMOLED display with FHD+ resolution and a 120Hz adaptive refresh rate. The display is vibrant and sharp, making it ideal for multimedia consumption and gaming. It also supports HDR10 content, enhancing the viewing experience on streaming platforms. With a peak brightness of up to 1600 nits, the screen remains visible even under direct sunlight. The display is protected by AGC DT-Star D+ glass, offering resistance against scratches.

Performance

The device is powered by the Qualcomm Snapdragon 7 Gen 3 SoC, coupled with up to 12GB of RAM and 256GB of internal storage. While the chipset is capable of handling everyday tasks and moderate gaming, it's considered by some to be an older choice compared to newer options available in the market. The phone scored 8,90,102 on AnTuTu. The large 5,219mm² SuperCool VC system ensures efficient thermal management during demanding tasks. Oppo promises 72-month fluency protection, ensuring long-term smoothness.

Camera

The Oppo F31 Pro+ features a dual-camera setup, including a 50MP primary sensor with OIS and a 2MP monochrome lens. A 32MP front camera is housed in a punch-hole cutout for selfies and video calls. The camera supports various modes, including underwater photography, time-lapse, and 4K video recording at 30fps.

In daylight, the 50MP main camera captures sharp, detailed photos with vibrant colors. However, some reviews suggest that the colors can appear slightly subdued, and details may be underwhelming for the price. The absence of an ultrawide lens limits the camera's versatility. The phone excels at producing accurate skin tones and colors in selfies and low-light conditions.

Battery Life

Battery life is a standout feature of the Oppo F31 Pro+, thanks to its massive 7,000mAh battery. It provides impressive endurance for regular usage, easily lasting a day and a half, and sometimes even two days, between charges. In a PCMark battery test, the handset scored over 13 hours. The device supports 80W SuperVOOC fast charging, which can juice up the battery from 20 to 80 percent in around 56 minutes. The battery is designed to maintain its health for over five years. The phone also supports bypass charging, drawing power directly from the charger to minimize charge cycles and extend battery lifespan.

Software and Other Features

The Oppo F31 Pro+ runs on ColorOS 15 based on Android 15. Some reviewers have noted that the software includes bloatware. The phone has strong and stable signal even in challenging conditions. It also supports 5G carrier aggregation for faster browsing and streaming.

Conclusion

The Oppo F31 Pro+ prioritizes durability and long battery life, making it a reliable choice for users seeking a smartphone that can withstand the rigors of daily life. Its striking design and vibrant display add to its appeal, while the capable performance and decent camera system round out the package. However, potential buyers should consider the older chipset, the lack of an ultrawide camera, and the presence of bloatware before making a decision.
