vivo Y31d review for Pakistan: 7200mAh battery, 44W charging, UFS 2.2 and IP68/IP69 are major strengths, but its HD+ screen, 4G-only platform and no NFC limit the value.
Read review →The vivo Y31d is a purpose-built endurance phone: its 7200mAh battery, UFS 2.2 storage and IP68/IP69 protection are genuinely useful. The compromises are equally clear—HD+ resolution, no 5G, no NFC and no storage-card expansion. It makes the most sense when battery and durability outrank display sharpness and future connectivity.
Choose the vivo Y31d if you want very long battery life, strong ingress protection and UFS storage for everyday use. The 6GB/128GB version has the clearest value case. Compare carefully before paying for the higher variants because 4G-only connectivity and the HD+ panel become harder to justify as the price rises.

No. vivo Pakistan lists the Y31d as a 4G phone using the Snapdragon 6s Gen 2 4G platform. Buyers who specifically want 5G should choose another model.
The Y31d has a 7200mAh typical battery and supports up to 44W FlashCharge with compatible vivo charging equipment. Real charging time varies with temperature, battery level and use during charging.
vivo rates it IP68 and IP69 under controlled laboratory conditions. That gives it strong dust and water resistance, but it is not a professional waterproof phone, resistance can decrease with wear, and liquid damage is not necessarily covered by warranty.
