NeoTeo's verdict
Which of the two is the better buy
The vivo Y31d suits buyers who want performance and battery capacity, while the vivo Y31 is the pick for cameras, 5G, and expandable storage. Both have the same 5.3 overall score, but their priorities differ.
The Y31d uses a Snapdragon 6s 4G Gen 2, scores 410,556 in AnTuTu, and has UFS 2.2 storage, versus the Y31’s Snapdragon 4 Gen 2, 201,000 points, and eMMC 5.1. It also packs 7,200 mAh against 6,500 mAh and reaches 1,250 nits against 1,000 nits; both support 44 W charging. The Y31 is lighter at 209 g versus 219 g and adds MIL-STD-810H to IP68 and IP69.
The vivo Y31 is the better camera choice: its main camera uses f/1.8 and a Dual LED flash, while the Y31d has f/2 and an LED flash; its front camera is also f/2 versus f/2.1. Connectivity adds 5G, NFC, and a 3.5 mm audio jack, while storage reaches 512GB and supports expansion, versus 256GB with no expansion on the Y31d. The Y31d counters with Bluetooth 5.1 versus 4.2, Android 16 versus Android 15, and reverse charging; both share a 120Hz IPS LCD, 8GB of RAM, and stereo speakers.
