vivo Y31d Launches with Massive 7,200mAh Battery and Rugged IP69+ Rating
In a quiet announcement, vivo has introduced the Y31d, a new smartphone that distinguishes itself with exceptional battery capacity and rugged durability. While sharing design elements with the existing Y31 series, the Y31d carves its own niche by focusing on longevity and resilience, making it a potential standout for users with demanding needs.
Core Specifications and Design
The vivo Y31d is built around a 6.75-inch LCD display with a 120Hz refresh rate and a peak brightness of 1,250 nits, offering a smooth and viewable experience. The phone is powered by the Qualcomm Snapdragon 6s 4G Gen 2 chipset, paired with either 6GB or 8GB of LPDDR4X RAM and 128GB or 256GB of UFS 2.2 storage. It runs Android 16 with OriginOS 6 out of the box.
Available in Glow White and Starlight Gray, the device has a plastic composite body with a metal camera island. It measures 166.6 x 78.4 x 8.39mm (slightly thicker for the white variant) and weighs 219g. A side-mounted fingerprint reader provides security, and the device features stereo speakers.
Standout Features: Battery and Durability
The headline feature is undoubtedly the 7,200mAh BlueVolt battery, a significant step up from the 6,500mAh cells found in other Y31 models. This capacity translates to impressive endurance: over 13 hours of MOBA gaming, over 14 hours of navigation, or nearly 45 hours of continuous video playback. The battery supports 44W FlashCharge, capable of taking the phone from 1% to 50% in approximately 43 minutes, and includes a Bypass Charging feature for gaming while plugged in. The battery is reportedly rated for up to 6 years of use.
Complementing the long battery life is a robust IP69+ rating. This certification indicates protection against high-pressure, high-temperature water jets, dust ingress, and submersion in up to 1.5 meters of water for 30 minutes, making the Y31d suitable for harsh environments.
Camera and Connectivity
The camera system consists of a dual rear setup led by a 50MP main sensor with an f/2.0 aperture, accompanied by a 2MP auxiliary camera. An 8MP front-facing camera handles selfies and video calls.
As indicated by its chipset, the Y31d is a 4G-only device. It supports dual nano-SIM cards, dual-band Wi-Fi, and Bluetooth 5.1. Connectivity is rounded out by a USB 2.0 port. Notably, the phone lacks both NFC and a 3.5mm headphone jack.
Availability and Positioning
Initial availability appears focused on select markets. The device has been listed on official vivo websites for Cambodia and Vietnam. Pricing details have not been officially announced at this time.
The vivo Y31d positions itself as a device for users who prioritize battery life and durability over cutting-edge 5G connectivity. Its massive battery and high ingress protection rating make it a compelling option for travelers, outdoor enthusiasts, or anyone seeking a device that can reliably last through extended periods of heavy use.
