NeoTeo's verdict
Which of the two is the better buy
The vivo Y31t is the more balanced choice for buyers who want faster storage and a larger battery: it has UFS 3.1 versus eMMC 5.1 on the vivo Y31, and 7,200 mAh versus 6,500 mAh. Overall, they are closely matched. The Y31t leads on performance, while the Y31 leads on camera and connectivity.
The Y31t screen reaches 1,200 nits, compared with 1,000 nits on the Y31, though both use a 120 Hz IPS LCD panel with 720 × 1,608 px resolution. The Y31 offers 8 GB of RAM and up to 512 GB of storage; the Y31t has 6 GB and 256 GB. The Y31 also supports expandable storage and adds NFC and a 3.5 mm headphone jack, neither of which the Y31t has.
Both phones use the Snapdragon 4 Gen 2 and support 44 W charging. The Y31t comes with Android 16 and direct OS updates, while the Y31 runs Android 15. For cameras, the Y31’s rear dual LED flash and front f/2 aperture differ from the Y31t’s LED flash and f/2.1 front aperture.
