The Redmi 15C 5G and vivo Y21 5G share a MediaTek Dimensity 6300 chipset and 120Hz, 720p-class displays, but their listed specifications differ in screen size, battery, charging, cameras, and protection rating. In the India listings checked, Xiaomi advertised the Redmi from ₹18,499, while vivo listed the Y21 5G 4GB+128GB at ₹32,999 MRP and showed that selection as unavailable. Those figures use different price bases and are not a like-for-like street-price comparison.

Specifications above come from the manufacturers’ India product pages: Xiaomi Redmi 15C 5G specifications and vivo Y21 5G specifications. They describe listed hardware and features, not results from an independent head-to-head test.
Performance: same listed chipset, no head-to-head result
Both India specification pages list the MediaTek Dimensity 6300 built on a 6nm process. That makes the chipset a shared specification, but it does not establish identical performance in everyday use: no comparable independent benchmark or test result is available here. RAM and storage configurations can also affect a particular listing, so check the exact variant before buying.

Xiaomi lists a 6.9-inch display with a 1600×720 resolution and refresh rates up to 120Hz. vivo lists a 6.74-inch panel at the same resolution and up to 120Hz. The Redmi is therefore larger by the stated diagonal, while both have the same listed pixel dimensions and maximum refresh rate.

Xiaomi states 660 nits typical brightness and 810 nits in HBM. vivo’s product page markets 1200 nits, but brightness figures can use different modes or measurement conventions. Without aligned methods and conditions, those figures should not be treated as a direct brightness test between the phones.
Battery and charging: vivo has the higher listed figures
vivo lists a typical 6500mAh battery and 44W charging; Xiaomi lists a typical 6000mAh battery and 33W charging support. Xiaomi also lists a 33W charger in the box. The vivo India store listing says a charger is included, but check the box contents for the specific regional SKU and seller.

The capacity and wattage figures do not by themselves predict screen-on time or charging time. Actual battery life varies with signal strength, brightness, apps, and other use, while charging speed depends on the charging curve and conditions.

The Redmi lists a 50MP main rear camera and an 8MP front camera. The Y21 5G lists a 50MP + 0.08MP rear setup and a 5MP front camera. On resolution alone, the Redmi has the higher stated front-camera megapixel count; megapixels do not establish which phone takes better photos. The specifications do not provide a controlled comparison of image quality.

Protection ratings: IP65 and IP64 are not waterproof claims
The vivo Y21 5G is listed as IP65 and the Redmi 15C 5G as IP64. These codes classify resistance to dust and water exposure under defined test conditions; neither rating means a phone is waterproof or safe to immerse. Xiaomi specifically warns against immersion and says protection can degrade with use. Treat both devices as phones with limited ingress protection, not as waterproof devices.
Software and update support
Xiaomi lists HyperOS 2 based on Android 15 for the Redmi 15C 5G, with two years of OS updates and four years of security updates. vivo lists Android 16 with OriginOS 6 for the Y21 5G, but the reviewed India product page does not state a comparable update duration. That page difference does not establish that vivo will provide no updates; it means a support-period comparison cannot be made from the published statements cited here.

India price difference: the checked listings are not like-for-like
On Xiaomi’s India phone listings, the Redmi 15C 5G was advertised “From ₹18,499,” alongside a marketing price of ₹29,999. The vivo India Store Y21 5G listing showed ₹32,999 MRP for the 4GB+128GB configuration, with that selected listing marked unavailable. Xiaomi’s India phone listings and vivo’s store use different price bases here: an advertised starting price and marketing price versus an MRP for a named configuration.
These figures are an observed official-listing snapshot, not a verified current street-price difference. The variants and sale conditions are not established as equivalent, and the vivo listing was unavailable when checked. For a fair comparison, check current stock and the exact RAM/storage configuration, then compare prices from the same marketplace or similarly comparable sellers. Do not calculate a precise saving from these figures alone.

Which phone fits your priorities?
- Consider the Redmi 15C 5G if you want the larger listed screen, a higher-resolution listed front camera, and Xiaomi’s stated OS and security update durations.
- Consider the vivo Y21 5G if its larger stated battery capacity, higher charging wattage, and IP65 rating matter more to you.
- For performance, the listed chipset is the same, so these specifications alone do not identify a winner.
- For price, compare equivalent configurations at checkout. The published India figures differ in price basis and availability.
For a purchase, verify that a listing is the 5G model, confirm its RAM and storage, seller, stock, and current price, and check included accessories for the regional SKU. Manufacturer specifications are useful for narrowing the choice, but they do not substitute for comparable testing of real-world speed, photo quality, battery life, or charging time.
