NeoTeo's verdict
Which of the two is the better buy
The vivo Y31d is the most complete choice for performance, display and battery: its Snapdragon 6s 4G Gen 2 reaches 410,556 in AnTuTu, versus 252,597 for the Y11d and 222,000 for the Y21d, while pairing UFS 2.2 storage with 7,200 mAh. The vivo Y21d is the better fit when water resistance matters most, rated to 6 m versus 1.5 m for the Y31d; the Y11d does not offer the same protection.
The Y31d combines 1,250 nits and 120 Hz, compared with 1,200 nits and 120 Hz on the Y11d and 1,000 nits and 90 Hz on the Y21d. All three use IPS LCD and provide 46 hours per cycle, but the Y31d adds 7,200 mAh against 6,500 mAh in the other two. The Y11d and Y21d weigh 209 g each, while the Y31d weighs 219 g.
The Y21d is a balanced alternative for anyone who values IP68, IP69 and MIL-STD-810H, along with expandable 256 GB storage and a Si-Carbon Li-Ion battery. The Y11d also supports expandable storage up to 256 GB and reaches 120 Hz, but uses eMMC 5.1 and tops out at 128 GB; its practical advantages are a 3.5 mm jack and infrared. The Y31d brings an 8 MP front camera versus 5 MP, although the three remain level overall for camera and connectivity.
