Description
Overview & Display
Vivo vivo Y31 combines a practical 8.4mm body with a substantial 209g weight, giving it a solid presence in the hand. Its IP68/IP69 rating provides dust protection and resistance to high-pressure water jets, while the phone can be immersed up to 1.5 metres for 30 minutes. It also carries MIL-STD-810H compliance, although this does not guarantee ruggedness in extreme conditions. The 6.68-inch IPS LCD offers a smooth 120Hz refresh rate and up to 1000 nits in high-brightness mode. Its 720p resolution is modest, but the large screen, stereo speakers, and 24-bit/192kHz Hi-Res audio support make Vivo vivo Y31 well suited to everyday video and music playback.
Performance comes from the 4nm Snapdragon 4 Gen 2, using an octa-core design with performance-focused Cortex-A78 cores and efficiency-focused Cortex-A55 cores. That setup is aimed at routine browsing, messaging, streaming, and general app use rather than demanding flagship-level workloads. The phone is offered with 4GB or 6GB of RAM and 128GB of internal storage. Storage can be expanded through a microSDXC card, though the shared slot means choosing between expandable storage and a second SIM. Android 15 with Funtouch 15 provides the software foundation, while the 6GB configuration should offer more comfortable multitasking.
Camera & Battery
Vivo vivo Y31 uses a single 50MP main camera with an f/1.8 aperture, PDAF, and an auxiliary lens. On paper, this provides a straightforward setup for everyday photography, with autofocus assistance available for supported shots. A Ring-LED flash is included for darker conditions, while panorama mode adds a wider shooting option. Rear video recording is limited to 1080p at 30 frames per second, so the camera is best suited to standard Full HD clips rather than higher-resolution recording. The front-facing 8MP wide camera also records at 1080p and is designed for video calls, selfies, and basic personal video capture.
The 6500mAh battery is one of Vivo vivo Y31’s most practical features, offering a generous capacity for users who spend long periods browsing, watching content, or communicating away from a charger. Charging is handled through 44W wired charging, with the stated ability to reach 50% in 38 minutes. Reverse wired charging is also supported, allowing the phone to provide power to compatible accessories or another device when needed. Together, the large battery and relatively efficient 4nm chipset make the phone a sensible choice for users who prioritise endurance and convenient top-ups.
Who Should Buy This
Vivo vivo Y31 is a good fit for users who want a large, smooth 120Hz display, strong battery capacity, dual-SIM support, and 5G connectivity in one practical handset. It suits streaming, social media, messaging, navigation, video calls, and everyday photography, while the IP68/IP69 protection adds reassurance for regular exposure to dust or water. The 6GB version is the better choice for people who frequently switch between apps. Buyers seeking advanced photography controls, NFC payments, a headphone jack, or especially sharp high-resolution display output may want something different. It is also less suited to demanding gaming or intensive creative workloads.
Pros
- Large 120Hz display with 1000-nit high-brightness mode
- 6500mAh battery with 44W wired charging
- IP68/IP69 protection against dust and water
- 5G connectivity with dual-SIM support
- Stereo speakers with Hi-Res audio support
Cons
- 720p display resolution is relatively modest
- No NFC or 3.5mm headphone jack
- microSD card uses the shared SIM slot
- Rear video recording is limited to 1080p at 30fps
Verdict
Vivo vivo Y31 focuses on practical strengths: a large 120Hz screen, a high-capacity battery, fast wired charging, 5G support, and substantial dust and water resistance. Its Snapdragon 4 Gen 2 platform should handle everyday tasks effectively, particularly with 6GB of RAM. The main compromises are the 720p display, eMMC 5.1 storage, basic camera setup, and missing NFC and headphone jack. For users prioritising endurance, durability, and routine smartphone use, it is a well-rounded option.
