Introduction
The smartphone market in 2025 is full of options, but few devices manage to strike the perfect balance between performance, durability, and affordability. Vivo has always been a strong player in the mid-range segment, and its latest launch, the Vivo Y31 5G, continues this tradition.
The phone is designed for users who want long battery life, a rugged build, and smooth everyday performance without stretching their budget. With a massive 6,500 mAh battery, Snapdragon 4 Gen 2 processor, IP68/IP69 water and dust resistance, and a 120 Hz display, the Vivo Y31 5G is one of the most reliable smartphones available in the sub-₹17,000 price bracket.
In this comprehensive review, we’ll cover every detail about the device — from design and build quality to display, hardware, camera performance, software experience, battery life, and pricing. By the end, you’ll know exactly whether the Vivo Y31 5G is the right fit for your needs.
Design and Build Quality
The Vivo Y31 5G is built like a tank while still maintaining a modern aesthetic. At 209 grams with dimensions of 166.14 × 77.01 × 8.39 mm, it is slightly heavy, but this weight contributes to its sturdy and reliable feel in hand.
One of the most impressive aspects is its IP68/IP69 water and dust resistance, which is rare in this price range. On top of that, the device is MIL-STD-810H certified, ensuring protection against drops, shocks, and extreme conditions. This makes it an excellent choice for users who work outdoors, travel frequently, or simply want a phone that can handle rough use.
The rear design is clean and minimal, with the camera module placed neatly at the top-left corner. The side-mounted fingerprint scanner doubles as a power button, offering both security and convenience.
Color options include Rose Red and Diamond Green, both of which give the device a stylish edge without being too flashy.
Key Design Highlights:
- IP68/IP69 water and dust resistance
- MIL-STD-810H military-grade durability
- Side-mounted fingerprint sensor
- Weight: 209 g | Thickness: 8.39 mm
- Colors: Rose Red and Diamond Green
Overall, the Vivo Y31 5G scores high in build quality, making it a durable companion for long-term use.
Display
The phone features a 6.68-inch LCD panel with a 120 Hz refresh rate, designed to deliver smooth visuals while scrolling, gaming, or watching videos.
Although it is an LCD panel instead of AMOLED, the addition of 120 Hz refresh rate makes the overall experience fluid. It also supports 1,000 nits peak brightness (1,050 nits on the Pro variant), which means outdoor visibility is not an issue.
To protect the screen, Vivo includes Guardian Glass protection along with TÜV Rheinland certification, which reduces harmful blue light and protects your eyes during extended usage.
The only real drawback here is the HD+ resolution (1612 × 720 pixels). While colors are bright and contrast is good, sharpness could have been better with a Full HD+ panel, especially at this screen size.
Display Highlights:
- 6.68-inch LCD panel
- 120 Hz refresh rate for smooth scrolling
- Peak brightness: 1,000 nits
- Guardian Glass protection
- TÜV Rheinland eye protection
- HD+ resolution (lower than rivals in this range)
If you’re someone who values smooth refresh rate and brightness over pixel density, this display will satisfy your needs.
Performance and Hardware
The Vivo Y31 5G is powered by the Qualcomm Snapdragon 4 Gen 2 chipset, a 5G-enabled processor built for efficient performance. Paired with 4 GB or 6 GB of RAM and 128 GB storage, it is more than capable of handling day-to-day tasks like browsing, social media, video calls, and casual gaming.
For users who engage in heavier multitasking or gaming, the 6 GB RAM variant is recommended, as it offers smoother switching between apps. Storage is expandable via microSD card, giving you flexibility for media-heavy usage.
The Snapdragon 4 Gen 2 chipset ensures balanced performance and battery efficiency. While it may not be a gaming beast like higher-end Snapdragon 7 series processors, it delivers consistent results in the mid-range segment.
The device also includes stereo speakers, enhancing the multimedia experience whether you’re streaming, gaming, or on calls.

Camera Performance
The camera setup on the Vivo Y31 5G is basic yet functional. It comes with a 50 MP primary rear camera accompanied by a 0.08 MP depth sensor. On the front, there’s an 8 MP selfie camera.
The 50 MP sensor is capable of capturing bright, sharp photos in daylight conditions. Vivo also includes AI-based enhancements, such as AI Erase for object removal and Super Night Mode for low-light photography. While nighttime shots are acceptable, they lack the detail and sharpness you’d get with higher-end models.
The depth sensor doesn’t add much value, but it helps slightly with portrait effects. The 8 MP front camera is decent for selfies and video calls, offering natural skin tones and adequate brightness.
For video recording, the phone supports 1080p recording at 30fps, which is standard for its class.

Battery Life and Charging
This is where the Vivo Y31 5G truly shines. Equipped with a 6,500 mAh battery, it easily lasts more than a day and a half on moderate usage, making it one of the best in its class.
Whether you’re a heavy social media user, gamer, or someone who streams content for hours, this battery ensures that you won’t be reaching for the charger frequently.
When it comes to charging, the phone supports 44 W fast charging through a USB-C port. It may not be as fast as 65 W or 80 W charging found in premium devices, but given the battery size, it offers a good balance between speed and battery health.
Battery Highlights:
- 6,500 mAh battery capacity
- 44 W fast charging support
- USB-C port
- 1.5 days of backup on regular use
This makes the Vivo Y31 5G an excellent choice for users who prioritize long-lasting power.
