The Vivo Y31 5G is a mid-range smartphone designed for users who want 5G connectivity, a large display and long battery life for everyday use. It features a 6.68-inch IPS display with HD+ resolution of 720 × 1608 pixels and a 120Hz refresh rate. The higher refresh rate helps scrolling and supported animations look smoother, while the waterdrop notch houses the front camera. Its ion-strengthened Guardian Glass adds a layer of screen protection.
The phone has a 209g body and comes in Rose Red and Diamond Green. Its IP68/IP69 ratings indicate strong protection against dust and water under specified test conditions. The device is also listed with water resistance up to 1.5 metres for 30 minutes, although users should avoid deliberate submersion and follow Vivo’s warranty guidance.
Powering the Vivo Y31 5G is the Qualcomm Snapdragon 4 Gen 2 processor, paired with 6GB RAM and 128GB of eMMC 5.1 storage. It also supports up to 6GB of virtual RAM. This hardware is suited to everyday tasks such as messaging, browsing, video streaming and casual gaming, though demanding games and intensive multitasking may expose its performance limits.
For photography, the phone has a 50MP f/1.8 rear camera with autofocus and LED flash. It records rear video at up to 1080p at 30 frames per second. The 8MP f/2 front camera supports Full HD video recording and features such as HDR, portrait effects and screen flash for selfies.
The Vivo Y31 5G runs Android 15 and includes AI tools listed as AI Erase, AI Photo Enhance and Circle to Search. Connectivity options include 5G, dual-SIM standby, Wi-Fi, Bluetooth 4.2, USB-C 2.0 and GPS support. It also offers a side-mounted fingerprint reader, face unlock and dual stereo speakers, but lacks a 3.5mm headphone jack and FM radio.
A 6,500mAh battery powers the device, with support for 44W fast charging. Overall, the Vivo Y31 5G focuses on extended battery life, a smooth-refresh-rate screen, basic camera versatility and everyday connectivity.
The Vivo Y31 5G is worth considering for buyers who prioritise battery capacity, 5G access and practical everyday features over premium performance. Its 6,500mAh battery should be a major attraction for people who spend long hours browsing, watching videos, attending online classes or travelling. The 44W charging support is also useful when the phone needs to be topped up, although actual charging time depends on usage, temperature and the supplied adapter.
The 120Hz display is another advantage for users who value smoother scrolling. However, its HD+ resolution is less sharp than the Full HD+ panels available on some competing phones, especially when reading small text or viewing detailed content. The Snapdragon 4 Gen 2 is appropriate for routine apps and casual games, but buyers who regularly play graphics-intensive games or edit video should consider a more powerful chipset.
The 50MP rear camera provides a useful resolution for everyday photography, while the 8MP selfie camera covers video calls and casual self-portraits. Still, the listed camera setup is relatively simple, and buyers should not expect the versatility of phones with dedicated ultrawide or telephoto cameras. Full HD recording is suitable for routine clips, but it does not offer 4K video according to the supplied specifications.
Its IP68/IP69 protection ratings are notable for this segment, provided the exact regional model carries these certifications. Bluetooth 4.2 and eMMC 5.1 storage are older standards, and the lack of a headphone jack may inconvenience users with wired earphones.
Verdict: The Vivo Y31 5G is best suited to students, everyday users and people who want a large screen, long battery life and 5G connectivity. Buyers who value sharper display quality, advanced photography or high-end gaming performance should compare alternatives before choosing it.
