Vivo has officially introduced the Vivo Y31, the newest member of its popular Y-series lineup. Positioned as a budget-friendly smartphone, the Y31 manages to blur the line between entry-level and mid-range devices thanks to its massive battery, rugged durability, and modern software features.
Big Battery, Big Endurance
The star feature of the Vivo Y31 is its 6500mAh battery, far larger than what most devices in this segment provide. It also supports 44W fast charging, ensuring users spend less time charging and more time using their phone. For most people, the Y31 can easily last up to two full days on a single charge, even with demanding use like streaming, browsing, and gaming.
Rugged Durability with IP68/IP69 Protection
In addition to its large battery, the Vivo Y31 boasts IP68/IP69-rated water and dust resistance. This level of protection means it can handle immersion in water as well as high-pressure jets, making it a rare feature in the budget category. Outdoor users, travelers, and those prone to accidents will find this feature especially valuable.
Display and Performance
The smartphone features a 6.68-inch IPS LCD display with a resolution of 720 × 1608 pixels. While the resolution isn’t Full HD, Vivo compensates with a 120Hz refresh rate for smooth visuals and 1000 nits peak brightness, making the screen easy to use outdoors.
Powering the phone is the Qualcomm Snapdragon 4 Gen 2 chipset (2.2 GHz) paired with Adreno 613 graphics. Buyers can choose between 4GB or 6GB of RAM, both versions coming with 128GB of internal storage. This setup provides a solid balance of performance and efficiency for everyday use, social media, and light gaming.
Camera Setup
On the rear, the Y31 packs a 50MP main sensor (f/1.8) supported by a secondary 0.08MP depth sensor. For selfies and video calls, there’s an 8MP front camera. While not flagship-level, the camera system is reliable enough for social media, portraits, and casual photography.
Software and Features
Running on Funtouch OS 15 based on Android 15, the Y31 offers the latest software out of the box. Vivo has added its own set of customizations and optimizations for better performance in gaming and multimedia.
Design and Build
Despite its large battery, the Y31 is slim at 8.39 mm thick and weighs 209 grams. The smartphone is available in two bold colors — Diamond Green and Rose Red — both of which give it a premium look well above its price range.
Pricing and Availability
The Vivo Y31 is available in two configurations:
-
4GB + 128GB: $179
-
6GB + 128GB: $199
The Vivo Y31 stands out in the budget segment by combining a massive battery, rugged waterproofing, and modern performance. It’s not just a phone for casual users but also an ideal companion for travelers, outdoor enthusiasts, or anyone who values endurance and durability without spending much. With its balance of features and affordability, the Y31 has strong potential to become one of the most popular budget smartphones of 2025.
