GoSolo Verdict

The Vivo Y31t is a sturdy, large-screened entry-level phone built for durability and everyday use rather than speed. It brings IP68 water resistance and a 7200 mAh battery to a budget segment where such features are still uncommon, but the low-res display and entry-class chip mean it's slow for any real workload.

Strengths · 4

IP68/IP69 water and dust resistance rare at this price and durability class—immersible to 1.5m for 30 minutes, which matters where phones take real punishment
7200 mAh battery is genuinely large for the category; likely to last two days of moderate use
120Hz display is smooth for scrolling even if the 261 ppi resolution is soft, and 1000–1200 nits brightness handles direct sunlight
Side-mounted fingerprint sensor is faster to reach than under-display, especially on such a tall phone

Trade-offs · 3

720p resolution on a 6.75-inch screen yields 261 ppi—text and icons look noticeably grainy compared to any mid-range phone, a constant visual compromise
Snapdragon 4 Gen 2 is entry-level; expect stutters in heavy apps, gaming, or multitasking—not a fast phone by 2026 standards
No microSD card slot and charging power not specified in the sheet, making it unclear whether this charges as slowly as rival budget phones
