The Vivo Y31s remains a practical choice for users seeking an affordable 5G smartphone without compromising on essential features. Designed for everyday productivity, media consumption, and reliable connectivity, this device balances hardware efficiency with a user-friendly interface. Below is a comprehensive breakdown of its capabilities, performance metrics, and real-world usability.
Design and Display
The Vivo Y31s features a 6.58-inch FHD+ LCD panel with a 2408×1080 resolution and a 90Hz refresh rate. The higher refresh rate delivers smoother scrolling and responsive touch input, which is noticeable in daily navigation and light gaming. The screen is protected by standard Gorilla Glass, and the bezels are moderately slim, maintaining a clean front profile.
The chassis is constructed from polycarbonate with a matte finish that resists fingerprints. Weighing approximately 186 grams, it sits comfortably in hand and slips easily into pockets. A side-mounted fingerprint sensor doubles as the power button, offering fast and consistent authentication. The inclusion of a 3.5mm headphone jack and a dedicated microSD slot adds practical value for budget-conscious buyers.
Performance and Software
Under the hood, the Vivo Y31s is powered by the Qualcomm Snapdragon 480 5G processor, built on an 8nm architecture. This chipset integrates the X51 5G modem, ensuring sub-6GHz connectivity across supported regions. The phone typically ships with 4GB or 6GB of LPDDR4X RAM and 64GB or 128GB of UFS 2.1 storage, both expandable via hybrid SIM tray.
The device runs Funtouch OS based on Android. While initial launch versions shipped with Android 11, later regional updates have brought Android 12 and 13 compatibility depending on the market. The software emphasizes clean navigation, app cloning, game mode optimization, and battery management tools. Day-to-day multitasking remains smooth, though heavy applications may require moderate settings for consistent frame rates.
Camera System
The rear camera module consists of a triple setup: a 13-megapixel primary sensor with f/2.2 aperture, a 2-megapixel macro lens, and a 2-megapixel depth sensor. The main camera delivers well-exposed photos in daylight with accurate color reproduction. Portrait mode benefits from the depth sensor, creating natural edge detection in good lighting. Low-light performance relies on Night mode, which reduces noise but requires steady handling or a tripod for optimal results.
The front camera features an 8-megapixel sensor optimized for video calls and social media content. It supports face beauty filters, HDR, and portrait background blur. Video recording caps at 1080p at 30fps on both front and rear cameras, with electronic image stabilization applied for smoother handheld footage.
Battery Life and Charging
A 5000mAh lithium-polymer battery serves as the foundation for all-day usage. With the 90Hz display and Snapdragon 480 efficiency, light to moderate users can easily stretch the charge across 1.5 days. Screen-on time typically ranges between 6 to 7 hours depending on brightness, network usage, and background activity.
The device supports 18W fast charging via USB Type-C. A full charge takes approximately 2 hours and 15 minutes from zero. The charger is included in the box, and adaptive charging algorithms help extend long-term battery health by regulating voltage during peak cycles.
Price and Availability
The Vivo Y31s targets the entry-level 5G segment. Pricing varies by region and storage variant, but it consistently undercuts mid-range competitors while offering comparable core specifications. It is available through official Vivo retailers, authorized electronics stores, and major e-commerce platforms. Regional promotions and trade-in programs frequently reduce the final purchase price.
