The Redmi answers with a curved AMOLED screen, microSD expansion, a lighter body and a lower-priced 6 GB entry model. Both share a 6.77-inch 120 Hz AMOLED panel, a 50 MP main camera, IP65 and Android 15. Everything below comes from vivo India’s and Xiaomi India’s listed specifications for the Indian market, not from our own testing.

Where the vivo T4 leads
Chipset tier
The Snapdragon 7s Gen 3 sits a tier above the Snapdragon 6 Gen 3 and has a slightly higher listed peak clock (2.5 GHz against 2.4 GHz). Both are 4 nm parts paired with LPDDR4X memory and UFS 2.2 storage. That tier gap suggests some headroom for demanding games and heavy multitasking, but no benchmark or frame-rate result has been verified here. Treat it as a spec-sheet advantage, not a measured one.

Battery and charging
The vivo lists 7,300 mAh with 90 W charging. The Redmi lists 5,800 mAh with 45 W. That is roughly 26% more rated capacity and double the charging wattage. vivo says the T4 is “the first smartphone in India offering 7300 mAh battery backup, according to internal research as of 21st March 2025”. That is a manufacturer claim tied to that date, not an independent survey. Rated capacity does not translate directly into screen-on hours, because software tuning and the chipset’s efficiency also matter.
Selfie resolution and RAM ceiling
The front camera is 32 MP on the vivo and 20 MP on the Redmi. Megapixels alone do not decide selfie quality. The vivo is also the only one offering a 12 GB RAM option.
#1 Best Overall
- Full GOOG Service: Same User experience as the local mobile version. It's manufactured by vivo China Headquarter Factory. We will help you to install full set of GOOG APPs. The frequencies supported cover main network bands. The package contains compatible charger with local standard. Needless to worry about the GOOG Service, language, charging and network compatibility. Since this is a China Version mobile phone, please note some contents might still be Chinese and may not be changed.
- PROFESSIONAL V-SLR CAMERA SYSTEM — 3+2 Z EISS Master Lens Array with dual 200MP sensors (1/1.12″ S ONY LYTIA 901 main + 200MP 85mm gimbal-stabilized telephoto) and a 50MP ultrawide.

Where the Redmi Note 15 SE 5G leads
- Expandable storage: Xiaomi lists microSD support up to 1 TB. vivo states ROM expansion is unsupported, so you must buy the right internal capacity upfront.
- Weight and thickness: At 178–182 g and as thin as 7.35 mm, the Redmi is noticeably lighter than the 199 g vivo. The difference is about 17–21 g, depending on the colour you choose.
- Curved display: The panel is curved, a styling choice some buyers prefer for the look and others avoid because of accidental edge touches and awkward screen protectors.
- Lower entry configuration: A 6 GB + 128 GB model exists, giving Xiaomi a cheaper way in if you do not need 8 GB.
Where they are effectively tied
Both have a 6.77-inch AMOLED panel at 2392 × 1080 with up to 120 Hz refresh. The vivo’s 5,000 nits is described as a local peak and the Redmi’s 3,200 nits as a peak, so the two numbers may not be measured the same way. Do not read the gap as a like-for-like difference in everyday brightness. Both phones pair a 50 MP main sensor with a 2 MP depth sensor, so the rear camera hardware looks the same on paper. Real image quality depends on sensors, optics and processing, and no comparative camera test is established here. Both carry IP65, which protects against dust and water jets but is not rated for submersion. Both ship with Android 15. Update commitments differ by brand and region, so check the current regional product page for the exact policy.

No dependable current price gap could be established. Third-party comparison pages showed differing price snapshots and availability from one version to the next, and the manufacturer pages list specifications rather than live transaction prices. Rather than quote a figure that may be stale, use this method:
Rank #2
- 6.3” HD+ Infinity Display with Curved Glass Design
- A.I Powered Dual Main 13MP+Depth Sensor with LED flash and 13MP Selfie
- 64GB Internal Memory, 3GB RAM. Micro SD up to 64GB; Octa-Core 1.6GHz Processor with ARM Cortex-A55 Chipset
- Super 4,000mAh Battery with Quick Charge, Fingerprint Sensor, and Android 9 Pie
- 4G LTE (2/4/5/12/17) 3G: (850/1700/1900): US compatibility Nationwide on all GSM Networks including AT&T, T-Mobile, Cricket, metro PCS, and others. Not compatible with CDMA networks like Verizon, Sprint and Boost mobile)
- Match the configuration. The only identical tiers are 8 GB + 128 GB and 8 GB + 256 GB. The vivo’s 12 GB model and the Redmi’s 6 GB model have no direct rival.
- Use the same seller for both phones, such as the brand’s own store or one marketplace, on the same day.
- Separate the listed price from the effective price. Note whether bank-card discounts, exchange bonuses or coupons are included, and whether they apply to your card or only to certain variants.
- Check what is in the box. Xiaomi lists a 45 W charger. Confirm whether the vivo bundles its 90 W charger in your listing, as this affects the true cost.
- Note the date you checked. Indian phone prices change often through sales and launch offers.
A practical rule: if the same-variant gap is small, the vivo’s larger battery and faster charging make it the stronger-value pick on specs. If the Redmi is clearly cheaper, you are mainly trading battery, charging speed and chipset tier for a lighter body, a curved screen and microSD.
