What CompareTab says about Vivo Y31 5G vs POCO F9 Ultra
POCO F9 Ultra has clear advantages in memory, battery capacity and display refresh rate over Y31 5G, with 12 GB of RAM versus 4 GB, 256 GB of storage versus 128 GB, a 8050 mAh battery versus 6500 mAh, and a 185 Hz display instead of 120 Hz. It also adds a higher-resolution rear camera (200 MP versus 50 MP), optical image stabilization on the main camera, an ultrawide rear camera, and 100W charging. Vivo Y31 5G, however, is around $619 cheaper, lighter at 209 g versus 235 g, and thinner at 8.39 mm versus 8.74 mm. The main trade-off is F9 Ultra’s extra RAM, storage, faster charging, battery capacity, and smoother display versus Y31 5G’s lower price and lighter, thinner build.
