vivo Malaysia Targets Blue-Collar Professionals With the Y31s

vivo Malaysia has officially launched the vivo Y31s, a budget-friendly yet powerful smartphone aimed squarely at Malaysian blue-collar professionals who need a device that won’t quit halfway through a 12-hour shift. Powered by a 6500 mAh BlueVolt battery, the Y31s pairs long-lasting endurance with military-grade durability and IP68 and IP69+ water resistance — a stack of features rarely seen at this price point.

Available in two colours inspired by the night scenery of Kuala Lumpur, the vivo Y31s comes in KL Midnight Purple and Glowing Black. KL Midnight Purple reflects the city’s vibrant skyline and tropical nights with cosmic-inspired details and silver accents, while Glowing Black draws from a starry galaxy with a deep, mysterious glow and subtle shimmering lights. The phone boasts a sleek quad-curved back, matte metal-style frame, a slim 8.39mm design, and a lightweight 209g weight for comfortable all-day carry. It also features a compact ring-shaped Dynamic Light that wakes up the camera module with animated colours for calls, notifications, charging, music and alerts, and can be personalised to match user style.

6500 mAh BlueVolt Battery Built to Last Five Years

The 6500 mAh BlueVolt Battery is the headline feature, and the engineering underneath is more interesting than the headline number suggests. vivo claims up to 1600 full charge and discharge cycles while holding at least 80% of its capacity in laboratory conditions — that’s about 5 years of usage for typical charging patterns. The architecture uses an ultra-high energy density 782 Wh/L design, providing about 18% higher density than standard graphite-based batteries and around 1000 mAh more capacity in the same volume.

A self-developed battery health algorithm optimises usage in terms of software and charging, with features like overnight charging protection, high temperature protection, real-time battery health display, and custom charging limits of 90% or 80% that further extend lifespan. The device also features Smart 44W FlashCharge with a 29-dimension safety protection system for overvoltage, overcurrent, temperature and short circuit safeguards, plus a high-efficiency 2:1 buck-boost IC chip with up to 98.5% efficiency. Intelligent multi-stage charging control, 43,200 temperature checks per day, and support for PPS fast charging round out the package.

For real-world endurance, vivo claims up to 9.6 days of standby, with intelligent sleep standby optimisation cutting drain during inactivity. Marathon streaming and extended viewing sessions are explicitly supported, and the all-day performance is engineered to handle continuous real-world usage — even after long hours of continuous driving.

IP68, IP69+, MIL-STD-810H — Built for the Worksite

Designed for people whose work takes them outdoors, on the road, and through unpredictable conditions, the vivo Y31s delivers a comprehensive durability system built around water, dust, and impact protection. The device features professional-grade IP68 and IP69+ dust and water resistance, surviving prolonged submersion and high-pressure, high-temperature water jets — making it capable in everyday spills and harsh working conditions alike. A triple water-resistant structural design ensures even better internal sealing.

Wet-Hand Touch and Underwater One-Tap Water Photography guarantee seamless usability in the rain, with wet hands, and when faced with unpredictable outdoor tasks. A water ejection system integrated into the phone quickly ejects residual moisture for continued performance after water exposure. IP6X Dustproof Protection takes durability further by sealing the device completely from fine particles for reliable performance in dusty or high-debris environments.

In terms of physical resilience, the vivo Y31s is SGS Gold Label 5-Star Premium Performance certified for 3.5-meter drop resistance, and is compliant with military-grade certified MIL-STD-810H standards, backed by a multi-angle drop testing framework. Guardian Glass with a dual ion-exchange strengthening process significantly improves puncture resistance, surface impact strength, and overall durability. The device has undergone rigorous reliability testing including extreme temperature endurance, multiple simulations of button and port use, and high-frequency drop scenarios.

Performance and Entertainment

Under the hood, the vivo Y31s is powered by the Qualcomm Snapdragon 4 Gen 2 platform with an octa-core architecture and top speed of 2.2 GHz, delivering 10% faster CPU performance than the previous generation. The 4nm advanced process provides better power efficiency while maintaining fast and responsive performance in apps, navigation, and entertainment. UFS 3.1 storage technology improves performance with up to 3x faster read and write speeds than the previous generation, up to 1800 MB/s.

Multitasking is supported with up to 8 GB + 8 GB extended RAM, allowing more than 25 active background apps. Storage goes up to 256 GB with smart storage compression. The Y31s is designed for long-term reliability and provides a smooth experience for up to 50 months, thanks to extensive hardware and software optimisation. Smart features include Origin Island for system updates and suggestions, AI Captions for real-time transcription and translation, and vivo Office Kit for easy cross-device file sharing. Privacy and security tools include Private Space and Theft Protection.

The 6.72-inch High-Brightness Eye Protection Display delivers up to 1050 nits of brightness for clear visibility in bright sunshine, with a 120 Hz refresh rate for smooth scrolling and fluid visuals. TÜV Rheinland Low Blue Light Certification and 1080P resolution round out the display package. Audio is handled by a powerful dual speaker system supporting vivo’s industry-leading 400% volume, with louder, clearer, and more immersive stereo audio.

The 50 MP HD Rear Camera and 32 MP Front Camera handle imaging, with AI Erase intelligently removing distractions, Underwater Photography using physical button controls, AI Photo Enhance, Live Photo, Dual-View Video, Multi-Style Portraits, and Stylish Night Filters.

Availability and First Sales Promotion

The vivo Y31s is available in 12GB (6+6) + 256GB starting at RM1,199. Customers can purchase at all vivo Concept Stores and online via https://www.vivo.com/my.

From 13 June to 30 June 2026, vivo is running a First Sales Promotion with exclusive rewards. Buyers will receive a complimentary RM50 Petrol Card, equivalent to 250KM of travel, limited to the first 1,000 customers on a first-come, first-served basis, alongside a 6 Months Extended Warranty. Customers can also enjoy flexible payment options through SPayLater with 6 months 0% interest installment and an additional RM100 discount for purchases above RM1,000.

Our Take

The vivo Y31s is an unusually well-targeted launch. Most budget phones in the RM1,000-1,300 range make trade-offs that hurt real-world durability — the Y31s keeps IP68, IP69+, MIL-STD-810H, and a 6500 mAh battery in the spec sheet, which is genuinely rare at this price. The 5-year battery health claim and 50-month smoothness promise are also ambitious, and if vivo delivers even partially on those, the Y31s becomes a serious value proposition for Grab drivers, delivery riders, factory workers, and outdoor tradespeople who hammer their phones daily.

The First Sales Promotion adds genuine value too: an RM50 Petrol Card offsets a meaningful chunk of monthly fuel costs for the target audience, and the 6-month extended warranty is useful insurance for a device that’s likely to be used hard. The main reservation is the chipset — Snapdragon 4 Gen 2 is solid for everyday tasks but won’t set any speed records for gaming or heavy multitasking. For the target user, that trade-off is the right one. If you’re a Malaysian blue-collar professional looking for an affordable phone that genuinely survives the worksite, the vivo Y31s is worth a serious look.
