The vivo Y31d has been quietly released, featuring a large 7,200mAh battery and an IP69+ rating for dust and water resistance. This new phone differentiates itself from the Y31 and Y31 Pro models primarily through its use of a 4G-only Snapdragon 6s 4G Gen 2 chipset. It also boasts a sizable battery, promising extended usage times.

The phone comes in Glow White and Starlight Gray. The Y31d includes a 6.75-inch LCD with a 120Hz refresh rate. It sports a 50MP main camera and an 8MP selfie camera. It also offers dual nano-SIM slots, stereo speakers, and a side-mounted fingerprint reader, catering to users who prioritize battery life and durability.

With a focus on battery longevity and ruggedness, the Y31d is targeted at consumers seeking a reliable device. While pricing details are currently unavailable, the phone is already listed on vivo's official websites in Cambodia and Vietnam. This strategy reflects vivo's continued expansion in Southeast Asian markets.

This release highlights vivo's strategy to offer different models to cater to various consumer needs. The focus on a large battery and 4G connectivity suggests it's aimed at markets where 5G infrastructure is not yet fully developed or where users prioritize battery life over the latest connectivity standards. The phone runs Android 16 / OriginOS 6.
