Vivo Y31s 5G Price & Launch: Snapdragon 4 Gen 2 and Complete Specifications
Vivo has launched the Vivo Y31s 5G in Malaysia with a specification set built around two standout features: a 6,500mAh BlueVolt battery with 44W FlashCharge and a triple IP rating of IP68, IP69, and IP69K+, making it the most water-resistant mid-range phone in its category. The Qualcomm Snapdragon 4 Gen 2 handles everyday performance and 5G connectivity, the display is a 6.74-inch Full HD Sunlight Display at 1,050 nits and the cameras are a 50MP primary, 2MP bokeh sensor and 32MP selfie.
The Vivo Y31s 5G price in Malaysia is RM 1,499, which converts to approximately Rs. 35,200 at current exchange rates. This is not a confirmed India price — Vivo India has not announced the Y31s 5G for the Indian market. The phone is available in Black and Purple through Vivo Malaysia's official website and authorized dealers. Here is every specification explained in full.
The triple IP certification is the Vivo Y31s 5G's feature that most distinguishes it from competing mid-range phones and warrants the most detailed explanation. Most mid-range phones carry an IP64 or IP65 rating. IP68, IP69, and IP69K+ are certification combinations that appear almost exclusively on rugged and industrial devices. Here is what each rating means and why it matters.
The Vivo Y31s 5G is sold in Malaysia at RM 1,499 for the single 8GB plus 256GB variant. At current exchange rates, this converts to approximately Rs. 35,200, though India pricing would differ from this conversion due to import duties, GST and local market positioning. Vivo India has not announced the Y31s 5G, and there is no confirmed launch date for India. Black and purple color options are available through Vivo Malaysia's official website and authorized retail partners across Malaysia.
The Triple IP Rating: IP68, IP69 and IP69K+ Explained
Most smartphones, including premium flagships, carry either IP67 or IP68 certification. IP68 is the standard for flagship water resistance. The Vivo Y31s 5G carries three simultaneous IP certifications — IP68, IP69 and IP69K+, which is an unusual combination for a consumer smartphone at any price and is almost never seen in mid-range devices.
Having all three simultaneously means the Vivo Y31s 5G passes water resistance tests across three distinct standards: submersion at depth (IP68), high-pressure water jets at standard temperature (IP69) and high-pressure jets at elevated temperature (IP69K+). A phone that only passes IP68 could still be damaged by high-pressure hosing or steam, scenarios that the IP68 standard does not specifically test. The Vivo Y31s 5G's triple certification addresses all three.
For everyday practical use, the IP68 certification is the most relevant for most buyers it covers accidental submersion in pools, sinks, and toilets, which are realistic water-damage scenarios for consumer smartphones. The IP69 and IP69K+ certifications are more relevant for users who work in environments involving cleaning hoses, kitchen steam or outdoor settings where the phone may be exposed to more forceful water contact than a rain shower or accidental splash.
IP69K+: The automotive-grade standard, IP69K+, was originally developed to protect industrial and automotive equipment, such as vehicle components, that must withstand pressure washing in manufacturing environments. A consumer smartphone certified to IP69K+ has passed tests involving water jets at 80 degrees Celsius and 100 bar pressure at a distance of 10 to 15 centimeters. This is significantly more demanding than the water resistance tests used for IP68. The K in IP69K is a German standards suffix indicating conformity with the DIN 40050-9 automotive component protection standard.
Why triple IP certification matters in a mid-range phone: Most mid-range phones at prices comparable to the Vivo Y31s 5G carry IP64 (splash-only, no submersion) or IP65 (water jets, no submersion). Neither protects against dropping the phone in water. The Y31s 5G's IP68 alone would be above mid-range standard. IP68, IP69, and IP69K+ together position the Vivo Y31s 5G's durability at a level typically reserved for rugged phones that cost significantly more or for flagship-tier devices from Samsung and Apple.
IP rating comparison across price tiers: The Samsung Galaxy S25 Ultra has an IP68 rating. Apple iPhone 17 carries IP68. Vivo Y31s 5G carries IP68+IP69+IP69K. The mid-range phone in this comparison is certified to a higher combined water resistance standard than the most expensive flagship smartphones. This does not mean the Y31s 5G is better overall — the S25 Ultra and iPhone 17 have vastly superior chips, cameras and displays but on the specific dimension of water resistance certification, the Y31s 5G's triple certification is unusual.
Vivo Y31s 5G Processor: Snapdragon 4 Gen 2 and Performance
The Vivo Y31s 5G is powered by the Qualcomm Snapdragon 4 Gen 2, Qualcomm's entry-level 5G chipset positioned for budget-to-entry mid-range devices. The Snapdragon 4 Gen 2 is built on a 4nm process and handles everyday tasks social media, streaming, WhatsApp, casual gaming and navigation — smoothly without the thermal issues that older 6nm and 8nm budget chips exhibited under load. It includes an integrated 5G modem supporting sub-6GHz 5G bands relevant to Indian carriers Jio and Airtel.
The 8GB LPDDR4X RAM and 256GB UFS 2.2 storage configuration is generous for the Snapdragon 4 Gen 2's tier. At 8GB RAM the phone handles multiple apps simultaneously without forced background kills, and 256GB provides ample room for apps, photos, videos and offline content without immediate need for expansion. The Snapdragon 4 Gen 2 is not a gaming chip; demanding 3D games at high settings will encounter frame rate drops, but for casual gaming in popular titles like BGMI on medium settings it performs adequately.
The 6,500mAh battery combined with the Snapdragon 4 Gen 2's 4nm efficiency means battery endurance is one of the Vivo Y31s 5G's practical strengths. A more efficient chip draws less power per task, translating the large battery's capacity into more hours of actual screen time than an older less efficient chip would produce from the same cell.
Display: 6.74-Inch Sunlight Display at 1,050 Nits
The Vivo Y31s 5G features a 6.74-inch Full HD display with up to 1,050 nits peak brightness. Vivo markets this as a Sunlight Display, reflecting its 1,050-nit brightness, which keeps the screen readable in direct outdoor sunlight. The display type is not explicitly specified in Vivo's Malaysia launch materials as AMOLED or LCD, though the Full HD resolution and brightness specifications are consistent with either a high-quality LCD panel or a standard AMOLED. The comparison table below includes this as an unconfirmed point.
At 1,050 nits the display is comfortably readable in bright outdoor conditions. The refresh rate has not been specified in the Malaysia launch materials — a gap in the official information worth noting. For a phone at this price tier a 120Hz or 90Hz refresh rate would be standard; if the panel is 60Hz it would be a notable limitation relative to competing phones in this price range that have moved to 120Hz as standard.
Display refresh rate not confirmed: The Vivo Y31s 5G Malaysia launch materials do not specify the display refresh rate. This is an important specification to verify at India launch if Vivo India announces the phone. At RM 1,499 (approximately Rs. 35,200) a 60Hz display would be a significant limitation compared to competing phones with 120Hz AMOLED displays at lower prices.
Cameras: 50MP Primary, 2MP Bokeh and 32MP Selfie
The Vivo Y31s 5G camera system is a dual-rear setup: a 50MP primary camera and a 2MP bokeh sensor. It is important to clarify what the 2MP bokeh sensor does: it is a depth sensor that measures the distance from the camera to the subject, helping the software create the portrait mode background blur effect. It does not serve as a second camera for photography, it captures no usable photographs on its own. Buyers who want a real ultrawide or telephoto second camera should look at competing phones in this comparison that carry 8MP ultrawide sensors.
The 50MP primary camera is the rear camera's meaningful photography component. At 50MP with standard mid-range optics the camera captures detailed daylight photos and manages moderate indoor lighting adequately. Portrait mode uses the 2MP depth sensor data to improve the software background blur, producing portrait shots with cleaner subject isolation than pure software blur without depth sensor assistance. The 32MP front camera is competitive for selfies at this price tier, providing enough resolution for reframing and cropping without significant quality loss.
2MP bokeh sensor context: Across the Android mid-range market, 2MP depth or macro sensors are often listed alongside the main camera to indicate multiple lenses, but their functional contribution to photography is minimal. A 2MP sensor captures approximately 0.16 megapixels of usable detail — it is an AI assistance sensor, not a camera. The Vivo Y31s 5G has one meaningful rear camera (50MP primary) assisted by a 2MP depth sensor for portrait mode. Buyers comparing camera setups should focus on primary sensor quality and any true ultrawide or telephoto lenses, rather than counting camera modules.
The 6,500mAh BlueVolt battery with 44W FlashCharge is the Vivo Y31s 5G's other headline specification alongside the triple IP rating. BlueVolt is Vivo's battery technology designation for cells engineered for longevity and energy density. At 6,500mAh the phone provides two full days of moderate use and a comfortable single day of heavy use. The 44W FlashCharge fills the 6,500mAh from empty in approximately 90 to 100 minutes. A 20-minute charge at 44W provides approximately 4 to 5 hours of additional endurance.
The combination of IP68 certification for water protection and a large 6,500mAh battery is particularly useful for buyers who use their phone in outdoor and active environments — construction sites, sports, hiking, outdoor work where both the risk of water exposure and the inability to charge frequently are daily realities. The Vivo Y31s 5G's durability and battery combination is specifically designed to serve this user profile alongside the standard consumer mid-range buyer.

Final Verdict
The Vivo Y31s 5G is a phone with one genuinely unique specification in its price tier: the triple IP68, IP69, and IP69K+ water and dust resistance certifications. This is not a gimmick — these are three distinct international certification standards that the phone has passed individually, representing a durability commitment that most flagship smartphones and virtually no mid-range phones at this price carry. For buyers who specifically need this level of protection, the Vivo Y31s 5G is the mid-range phone that provides it.
The Vivo Y31s 5G's honest limitations at its RM 1,499 (approximately Rs. 35,200) price point are the Snapdragon 4 Gen 2 chip (entry-level 5G tier), the 2MP depth sensor that does not function as a real second camera, and the unconfirmed display refresh rate. Buyers who do not specifically need the triple IP certification will find better display quality, camera versatility, and chipset performance in AMOLED-equipped alternatives at lower prices in the Indian market. Watch Vivo India's official channels for the India launch announcement, where the India price will determine exactly how competitive the Y31s 5G is in the Indian market.
