vivo Y31 Pro

The vivo Y31 Pro is a performance-focused mid-range smartphone that blends strong hardware, a smooth display, and long battery life. Officially launched on September 15, 2025, this device targets users who want reliable speed, modern design, and dependable daily usability.

Design and Build Quality

vivo crafted the phone with a glass front and a plastic back and frame, which helps balance durability and weight. As a result, the device feels solid in hand while remaining comfortable for extended use. In addition, IP64 dust and splash resistance provides everyday protection, while MIL-STD-810H compliance adds extra confidence for rough handling, even though it does not guarantee extreme ruggedness.

Display and Visual Experience

The 6.72-inch IPS LCD display delivers sharp visuals thanks to its Full HD+ resolution (1080 × 2408 pixels). Moreover, the 120Hz refresh rate ensures smooth scrolling and fluid animations. With 1050 nits brightness (HBM) and 960Hz PWM dimming, the screen stays clear outdoors and remains comfortable for longer viewing sessions.

Performance and Software

Powered by the MediaTek Dimensity 7300 (4 nm) chipset, the vivo Y31 Pro handles daily tasks efficiently. Furthermore, the octa-core CPU improves multitasking, while the Mali-G615 MC2 GPU supports casual gaming and media consumption smoothly. Running on Android 15 with Funtouch OS 15, the phone delivers a clean and responsive user experience.

The device comes with 8GB RAM and up to 256GB UFS 3.1 storage, which ensures fast app loading and quick data access. However, the lack of a memory card slot means users should choose storage wisely.

Camera Performance

The 50MP primary rear camera captures detailed photos with accurate colors in good lighting. Additionally, the Ring-LED flash helps improve low-light shots, while 4K video recording at 30fps adds versatility. Gyro-EIS further stabilizes videos for smoother results.

On the front, the 8MP selfie camera handles video calls and casual selfies well, while supporting 1080p video recording.

Audio and Connectivity

The vivo Y31 Pro features stereo speakers, which provide louder and more immersive sound. Although the 3.5mm headphone jack is missing, the phone supports 24-bit/192kHz Hi-Res audio for high-quality wireless listening.

Connectivity options include dual-band Wi-Fi, Bluetooth 5.4, and multiple satellite systems for accurate navigation. Additionally, the infrared port allows the phone to work as a remote control for compatible devices.

Battery Life and Charging

A large 6500mAh battery keeps the phone running comfortably throughout the day and beyond. Moreover, 44W fast wired charging powers the device up to 50% in just 40 minutes, which reduces downtime. The phone also supports reverse wired charging, adding extra convenience.

Security and Sensors

For quick unlocking, the device uses a side-mounted fingerprint scanner. Along with it, sensors such as the accelerometer, gyro, proximity sensor, and compass ensure smooth and reliable operation.

Final Verdict

Overall, the vivo Y31 Pro stands out with its smooth 120Hz display, efficient Dimensity chipset, and massive battery life. While it skips expandable storage and a headphone jack, it still offers excellent value for users who want performance, endurance, and a modern Android experience.
