If you are comparing the 4GB+128GB versions in India, the vivo Y31 5G is the lower-priced choice in the official store snapshots: ₹19,999 versus ₹28,999 for the realme 16x 5G, a ₹9,000 gap. The realme offers a larger, up-to-144Hz display and a higher-capacity battery on paper; the vivo is lighter and its official listing specifies IP68/IP69 protection. Neither specification sheet establishes which phone performs better in everyday use.
How do their specifications compare?
The figures below are from the manufacturers’ India specification pages. Battery capacities are manufacturer ratings, and refresh rate is a stated maximum—not a measure of overall display quality.

|---|---|---|

What is the price difference in India?
For the matching 4GB+128GB configuration, the official-store listings accessed in 2026 showed ₹19,999 for vivo and ₹28,999 for realme. That is a ₹9,000 difference in those listings, not a guaranteed checkout price. The realme store also displayed an MRP of ₹48,999; that is not a like-for-like street-price estimate.

A separate 91mobiles comparison snapshot reported ₹19,999 at Flipkart for the vivo and ₹25,999 at Amazon for the realme. These are third-party-reported marketplace prices, not guaranteed current offers, and should not be conflated with the official-store prices above. Check the seller, variant, delivery charges, warranty region, and final checkout amount before ordering.

Which phone has the bigger battery?
The realme 16x 5G has the larger stated battery: 7000mAh typical, with 6820mAh rated capacity, compared with 6500mAh typical for the vivo Y31 5G. Its maximum stated charging rate is 45W, one watt above the vivo’s 44W FlashCharge specification. Those figures alone do not establish real-world battery life or how long either phone takes to charge; no directly comparable test results are available here.

Which display is the better fit?
The realme’s LCD is 0.13 inches larger and has a stated refresh rate of up to 144Hz. That ceiling may matter to buyers who prioritize smoother motion in supported content, but it does not establish better color, brightness, contrast, or overall image quality. Both screens are HD-class LCDs, and their listed resolutions differ slightly: 1608×720 on vivo and 1570×720 on realme.

Are the cameras or chipsets clearly better?
The specification pages list Snapdragon 4 Gen 2 for vivo and Dimensity 6300 for realme. They do not provide comparable benchmark results, so the model names alone are not enough to declare a performance winner. Likewise, both front cameras are listed at 8MP, while the rear-camera specifications are 50MP plus 0.08MP on vivo and 50MP on realme. Megapixel counts do not establish photo quality, and no comparable camera test or sample gallery is available here.
What about protection, handling, and what comes in the box?
vivo’s India product listing advertises IP68/IP69 protection. This is the manufacturer’s stated rating, not a reason to deliberately expose the phone to water; no independent durability test is cited here. The captured realme specification page does not state a protection rating, which should not be treated as proof that the device has none.

At 209g, the vivo is listed as about 8g lighter than the realme, which is listed at approximately 217g. Both manufacturers list a charger, cable, SIM eject tool, and protective case in the box. vivo also lists an applied protective film and warranty card; realme lists a quick guide. Contents can vary by market or seller, so confirm the box details for the unit you are buying.
Which one should you choose?
- Choose the vivo Y31 5G if the lower official-store price in the matching 4GB+128GB listings, lighter listed weight, or manufacturer-stated IP68/IP69 protection matters most to you.
- Choose the realme 16x 5G if you prefer the larger display, want its stated up-to-144Hz refresh option, or prioritize the larger rated battery capacity on paper.
- Compare the exact variant before paying. Both models are listed in 4GB+128GB, 6GB+128GB, and 6GB+256GB configurations, but the cited price comparison applies to 4GB+128GB, not every tier.
The realme India newsroom dated the 16x 5G India announcement to August 13, 2026. Confirm current availability and compatibility with your carrier’s bands before purchase; the cited specification pages do not settle compatibility for every network or region. Source: realme India announcement.
