vivo Y31s 5G Launches in Singapore: Clearer Display, IP69 Durability, and a 6500mAh Battery at S$399

vivo has just launched the vivo Y31s 5G in Singapore — a mid-range 5G phone that ticks the boxes most everyday users actually care about: a sharp display, a camera that won’t let you down, a battery that goes the distance, and a build tough enough to survive real life. Priced at S$399, it makes a strong case for itself in a crowded market.

A Clearer Display for Everything You Do

The Y31s 5G sports a 90Hz High-Brightness FHD Dotch Display that makes a noticeable difference whether you’re streaming, gaming, or just scrolling through social media. The Full HD resolution delivers sharpness and clarity that holds up well indoors and outdoors, while the 90Hz refresh rate keeps everything feeling fluid.

Cameras You’ll Actually Want to Use

The camera system gets a meaningful upgrade here. The 32MP HD front camera is a significant jump from the previous generation’s 8MP — your selfies and video calls will look noticeably better. On the back, a 50MP HD main camera captures everyday moments with vivid colours and strong detail. There’s also underwater photography support, so spontaneous poolside or beach shots are no problem.

A Battery That Keeps Going

Battery anxiety? The Y31s 5G’s 6500mAh BlueVolt Battery should put that to rest. It’s engineered for all-day use across communication, entertainment, and work tasks. When it does need a top-up, 44W FlashCharge gets you back up quickly. There’s even reverse charging on board — handy for topping up earbuds or a friend’s phone in a pinch. For the long haul, vivo has built in 5-Year Battery Health technology to keep performance stable years down the line.

Performance That Stays Smooth

Under the hood, the Snapdragon® 4 Gen 2 chip (built on a 4nm process) handles everyday tasks with efficiency and speed. Paired with up to 6GB Extended RAM, 256GB of storage, and the latest OriginOS 6, apps launch faster and multitasking stays smooth. vivo claims a 50-Month Smooth Experience — meaning this phone should still feel snappy years from now.

For entertainment, dual stereo speakers push up to 400% volume, delivering audio that’s genuinely loud and full for a phone at this price point.

Built Tough Without Looking It

The Y31s 5G is slim at 8.39mm and weighs around 209g — comfortable to hold and carry all day. But don’t let the sleek looks fool you: it’s rated IP69 for dust and water resistance, and carries SGS Five-Star Drop Resistance certification. Whether you’re caught in the rain or fumble your phone on a hard floor, it’s built to take the hit.
