The India-market Xiaomi Redmi Note 15 5G has the sharper AMOLED display and higher-resolution listed cameras; the vivo Y51 Pro 5G has a much larger stated battery and stronger dust- and water-resistance ratings. The vivo appeared at a higher price on one third-party comparison listing, but prices change and the listing does not establish a same-storage comparison. Available specifications alone do not prove which phone performs better in everyday use.
At a glance: Redmi Note 15 5G vs vivo Y51 Pro 5G
This comparison is for the India-market Redmi Note 15 5G and vivo Y51 Pro 5G. Redmi Note 15 has regional and network variants, so specifications for another Redmi model should not be assumed to apply to this one.

Which phone has the better display?
On the published details, Redmi has the more defined display specification: its 6.77-inch AMOLED panel is listed at 2392 × 1080. vivo lists a nearly similar 6.75-inch screen at 1570 × 720, with a refresh rate up to 120 Hz, but leaves the display-type field blank on its official parameter page. A 91mobiles comparison calls the vivo panel LCD; that is a third-party characterization, not a display type stated in vivo’s parameter table.

Both are listed at 120 Hz or up to 120 Hz, but refresh rate alone does not make the screens equivalent. The higher stated resolution and AMOLED designation make Redmi the clearer choice on display specifications; this does not replace a side-by-side assessment of brightness, calibration, or outdoor legibility.
Which phone has the bigger battery?
vivo specifies a 7,200 mAh typical battery and 44W FlashCharge. The Redmi India review configuration is reported with a 5,520 mAh battery and 45W wired USB-C charging. Redmi’s listed charging wattage is marginally higher, while vivo’s stated capacity is substantially larger.

Capacity and charging wattage do not establish real-world battery life or charging time. No matched battery or charging test is available here, so screen-on time, endurance under heavy use, and time to recharge cannot be fairly ranked from these figures alone.
How do the cameras compare?
Redmi lists a 108 MP main rear camera, an 8 MP ultrawide, and a 20 MP front camera. vivo lists 50 MP and 2 MP rear cameras plus an 8 MP front camera. Redmi therefore offers the higher stated resolutions and explicitly includes an ultrawide camera in the listed rear setup.

Megapixel counts do not determine photo quality by themselves. There are no directly comparable camera samples or independent tests in the available material, so the specifications cannot establish which phone takes better photos, especially in low light or video.
Which phone is more durable?
vivo specifies IP68 and IP69 ratings, while Android Central lists IP65/IP66 for the Redmi. These ratings describe protection under defined test conditions; they are not a promise that a phone is damage-proof. Water-resistance conditions and warranty coverage vary, so check each manufacturer’s current warranty terms before relying on either rating.

What is the price difference in India?
A 91mobiles comparison listing accessed in 2026 displayed ₹28,999 for Redmi Note 15 and ₹32,995 for vivo Y51 Pro, with Amazon price labels. On that listing, vivo was ₹3,996 more expensive. Those are volatile third-party displayed prices, not guaranteed current prices, and the listing does not confirm that both figures represent matching storage configurations. Check the current price for the exact model, storage tier, seller, and stock before comparing value. The listing is at 91mobiles’ phone comparison page.

Those are reported launch prices, not the later 91mobiles displayed prices or a current quote. vivo India’s newsroom said the Y51 Pro 5G would go on sale from 11 March 2026 through vivo’s official site, Flipkart, and partner retail stores; that announcement establishes launch availability, not current stock. See vivo India’s newsroom.
Which one should you choose?
- Choose Redmi based on the listed specifications if a higher-resolution AMOLED screen, an ultrawide rear camera, or higher stated camera resolutions matter most.
- Consider vivo based on the listed specifications if its 7,200 mAh typical battery or IP68/IP69 ratings are priorities, and its lower-resolution display is acceptable.
- Compare performance, photos, or battery life cautiously: the chipset names and published camera or battery figures are not substitutes for matched independent tests.
- For value, compare like with like: confirm the same RAM/storage tier, seller, and live price for both phones.
Software support periods are not established by the cited specifications, so compare current manufacturer support commitments separately if update longevity is important.
