Design and Build Quality
The Vivo Y31 5G has a solid first impression. With both IP68 and IP69 ratings, it is protected against dust, water immersion, and even tougher water jets. This level of ruggedness is rare in this price range. The body uses a composite plastic back and reinforced frame which helps reduce weight while maintaining durability. The side-mounted fingerprint sensor is integrated into the metal-inspired frame, and the matte frame finish gives a premium feel.
The phone comes in two colour options: Diamond Green and Rose Red. The matte back reduces fingerprints. The design also includes curved edges that help in grip despite its size. While plastic bodies are common in this segment, Vivo’s material finishing makes it feel less cheap than many rivals.
Display and Visual Performance
Vivo Y31 5G sports a 6.68-inch LCD display with HD+ resolution (1608 × 720), which isn’t full HD but the 120 Hz refresh rate helps scrolling and animations feel smoother. Peak brightness is strong (~1000 nits), making visibility under sunlight adequate. The pixel density is relatively modest (~264 PPI), so fine details may not be as sharp as higher-end phones.
Still, for video streaming, social media, and casual gaming, the display is quite usable. Colours are decent for an LCD, though not as punchy as AMOLED panels. The screen supports typical LCD features like blue-light filters and wet-touch functionality, which helps when hands are damp or in humid environments.
Processor, Performance and Software
Under the hood, the Vivo Y31 5G is powered by the Snapdragon 4 Gen 2 chip, built on a 4 nm process. This gives good efficiency and ensures the phone handles everyday tasks smoothly. Apps open quickly, multitasking between social media, messaging and light gaming is clean, though heavier games may show limitations due to RAM (4/6 GB) and GPU constraints.
The device runs Android 15 with Funtouch OS 15, which includes features like side-fingerprint unlock, gesture navigation, and some software enhancements for durability and performance. Vivo has done well to keep bloat apps minimal, and system updates are expected over a reasonable period for this segment.
Battery Life and Charging
Battery is one of the biggest draws. The 6500 mAh battery gives exceptional endurance — users can expect more than a full day of heavy usage, and up to two days or more with lighter usage. Whether browsing, streaming, or occasional gaming, the battery rarely becomes a worry.
Charging is via 44 W (some listings say 45 W) fast charging. It’s not the fastest in the industry but good enough to get decent charge quickly from low battery. Given the large battery, charging time from 0 to 100% will be longer than smaller battery phones, but the fast charger softens the wait significantly.
Camera System and Imaging
The rear camera setup is simple: a 50 MP main sensor + a tiny 0.08 MP helper lens. The main shooter captures good daylight photos, with decent color reproduction and dynamic range. Night or low light shots are average — some noise and softer details are visible. Portrait mode works okay, though the secondary sensor is minimal.
The front camera is 8 MP, enough for selfies, video calls, and social media use. While it won’t compete with high-end selfie cameras, it suffices in good lighting. Vivo includes several camera modes: Night, Portrait, Pro, etc. Video recording is capped at 1080p at 30 fps, which is standard for the segment.
Durability and Protection Features
IP68 and IP69 ratings mean that the Vivo Y31 5G is protected against dust ingress and water immersion (typical underwater use), and high-pressure water jets. This adds confidence for those who want a phone that can survive everyday accidents — rain, splashes, etc. The body is reinforced, and certain ports are well sealed.
However, over time seals may degrade; users should take care when using in water environments. Also, rugged doesn’t always equal rugged-rugged — drop protection is better than many phones here, but it’s not military spec drop safe in most circumstances.
Connectivity and Other Features
Vivo Y31 5G supports dual nano-SIMs with dual-standby 5G (SA / NSA), covering many 5G bands suitable for India. Bluetooth, Wi-Fi, GPS and other essentials are present. Some expected features like NFC depend on region, so check local variant features if this is important.
There is a side-fingerprint sensor, capacitive type, which is quick and usually reliable. Other sensors include proximity, ambient light, accelerometer. No gyro or barometer in many listings. The phone’s speaker setup is stereo-like but may not match premium stereo speakers in terms of loudness or depth.
Storage, RAM, and Expandability
Variants include 4 GB + 128 GB and 6 GB + 128 GB. The storage is eMMC 5.1, and there is support for microSD to expand storage (up to 2 TB in some listings). RAM is modest, so heavy multitasking might push it. But for everyday usage—calls, messages, social apps, light gaming—it works fine.
128 GB base storage is generous for this class, enabling enough space for photos, apps, videos without immediate need for expansion.
Pros and Cons of Vivo Y31 5G
Pros:
- Huge 6500 mAh battery delivers excellent endurance
- Durable build with IP68 and IP69 protection
- Decent 50 MP camera for day use
- Fast-fluid 120 Hz refresh rate helps in smooth UI experience
- Affordable pricing in 5G and durable phone category
Cons:

Who Should Buy Vivo Y31 5G
If you want a phone that can last long, survive rough conditions (rain, water, dust), and provide 5G connectivity at a reasonable cost, this is a strong pick. Students, commuters, or someone who uses their phone intensively but isn’t overly focused on premium camera performance would benefit.
If display sharpness, gaming performance, or ultra-fast charging are top priorities, you might need to look higher or consider competition.
Comparison with Competitors
Compared to other phones in similar price-5G-durable-battery segments, Vivo Y31 5G holds up well with its battery and durability rating. Some competitors may offer FHD+ displays, or more RAM or faster charging, but often at the trade-off of battery capacity or rugged features.
Models to compare: phones from Xiaomi / Redmi, Realme, Samsung’s A-series, etc. Depending on your priorities (battery vs display vs camera), you might pick different ones. Vivo Y31 5G gives a balanced approach especially for battery + durability.
Value Proposition and Price
In India, the Vivo Y31 5G is priced around ₹14,999 for 4 GB + 128 GB, and ₹16,499 for 6 GB + 128 GB. For what you get—battery, durability, basic good performance—this is competitive. It offers peace of mind for harsh usage (water, dust), long usage without frequent charging, and a newer 5G connection.
If one’s needs match what it offers, it delivers much of what someone might want without overpaying for features they may not use much.
Conclusion
Vivo Y31 5G may not be perfect, but in many ways it nails what it sets out to do. It’s not aiming to be flagship-level camera or ultra gaming performance, but that’s okay — because its strengths lie elsewhere. The large battery, rugged build, IP68/IP69 ratings, and decent processor all make this phone a reliable daily driver.
For someone looking for longevity, durability, and 5G without entering the premium price range, the Vivo Y31 5G is an excellent option. It’s a “big battery beast” that does what many phones promise but few deliver convincingly in this category.
