The Redmi Note 15 5G has the firmer specification footing: Xiaomi publishes its hardware details, while the detailed vivo S2 5G specifications and India prices available for comparison come from a community post, not an official vivo product page. On paper, the vivo is larger and has a higher reported battery capacity; the Redmi’s price advantage cannot be stated reliably without matching current local listings.
Check the exact Redmi Note 15 variant first
This comparison is for Xiaomi’s Redmi Note 15 5G, the model named on Xiaomi’s global specification page. Do not assume the figures apply to a Redmi Note 15 4G or another regional variant. Xiaomi also says network bands and NFC availability may vary by market, so confirm the handset’s regional identity before buying. Xiaomi’s global Redmi Note 15 5G specifications

For the vivo, the official evidence available here is narrower: vivo’s security page includes “S2 5G” in its device list, but does not provide product specifications or establish current retail availability. The hardware figures below are therefore attributed to a vivo community post by Anant Rawat, rather than presented as independently verified official specifications. vivo’s security page · vivo community post by Anant Rawat

What the specification differences mean
Display size and shape
The reported vivo display is 0.16 inches larger diagonally and curved, which may suit someone who prioritizes a larger viewing area. Xiaomi lists a flat 6.67-inch AMOLED display at 2392 × 1080 and up to 120 Hz. The vivo post describes its display as 1.5K and 120 Hz but does not provide a pixel resolution in the cited details, so the labels alone do not support a precise resolution comparison.
Processor and memory
Xiaomi names the Snapdragon 6 Gen 3 and lists four RAM/storage combinations, including configurations with up to 512 GB of built-in storage. The vivo post names a Dimensity 7360-Turbo and reports two configurations, both with 8 GB RAM. These model names and capacities are not a substitute for a direct performance test, and the available information does not establish which phone is faster in real use.

Cameras
Xiaomi specifies a 108 MP main camera, an 8 MP ultra-wide rear camera and a 20 MP front camera. The cited vivo post does not supply camera details, so there is not enough evidence here to compare camera resolution, lenses or image quality between the phones.
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Battery and charging
Xiaomi lists a 5520 mAh typical-capacity battery and 45 W turbo charging. The vivo community post reports 7050 mAh and 44 W charging. Those figures suggest a larger stated battery capacity for the vivo and a slightly higher charging-wattage figure for the Redmi, but they do not establish comparative battery life or charging time. Actual endurance and charging can depend on usage, software, accessories and conditions.

Price difference: why there is no dependable universal gap
The vivo community post reports India prices of ₹39,999 for 8 GB + 128 GB and ₹44,999 for 8 GB + 256 GB. Treat these as reported prices, not confirmed current retail prices. Xiaomi’s global specification page does not establish a country-specific price for the Redmi Note 15 5G.
Secondary comparison listings surfaced different vivo prices alongside a Redmi listing: ₹39,490 and ₹37,999 in two 91mobiles results, and ₹39,990 in a localized comparison result. These listings conflict and do not establish equivalent storage tiers, sellers, dates or offer terms. They cannot support a reliable general price difference. 91mobiles comparison result

To compare what you would actually pay, check both phones in your country at the same time, match RAM and storage as closely as possible, and compare the same kinds of sellers. Record whether the displayed price includes taxes and shipping or depends on a bank offer, exchange discount or other promotion. Also verify each phone’s regional model, bands and warranty before treating two listings as like-for-like.

- Consider the Redmi Note 15 5G if you want specifications published on Xiaomi’s product page, an explicitly listed ultra-wide rear camera, a 20 MP selfie camera, or a choice that includes higher-storage configurations.
- Consider the vivo S2 5G if a larger curved screen or its reported 7050 mAh battery is appealing—but verify the specifications, local availability, seller and warranty for the exact unit you are considering.
- Do not choose on a claimed price gap alone. The cited prices are not a confirmed, same-date comparison of matching configurations.
The available evidence does not settle software-update support, network-band compatibility for a particular country, warranty terms or the vivo’s camera setup. Check those details against the exact regional model and seller before purchase.
What the vivo community post says is in the box
The poster reports that the S2 5G package includes a 44 W adapter, USB-C cable, transparent case, pre-applied screen protector, SIM ejector, and quick-start and warranty documents. This is one poster’s account and should not be assumed to describe every country, seller or retail package. Xiaomi’s global Redmi page says a power adapter is not included and recommends compatible PD or Xiaomi 45 W adapters. Xiaomi’s global product page · vivo community post
