The Redmi Note 15 and vivo X300 FE are not a like-for-like comparison until you identify the Redmi’s region and connectivity version: Xiaomi publishes a 4G model for Mexico and a materially different 5G model for the UK. The available vivo specifications and prices here are India-specific. No matched Redmi price for a defined market, configuration and date is established, so there is no reliable universal price difference to quote.
First identify the exact Redmi Note 15
“Redmi Note 15” does not refer to one worldwide specification. The Mexico 4G model and UK 5G model differ in chipset, network support, rear cameras, battery capacity, charging and other details. Xiaomi also cautions that specifications and contents can vary by region. Check the model name and local SKU on the box or product listing before using this comparison.

The comparison below uses Xiaomi’s Mexico specification page for the Redmi Note 15 4G, Xiaomi’s UK page for the Redmi Note 15 5G, and vivo’s India materials for the X300 FE. It is a comparison of manufacturer-published specifications, not an independently tested head-to-head review.

How the specifications differ in practice
Connectivity and chipset
The Mexico Redmi configuration is a 4G phone; do not assume it supports 5G because a different Redmi Note 15 version does. The UK Redmi 5G page lists a Snapdragon 6 Gen 3, while the Mexico 4G page lists a Helio G100-Ultra. vivo specifies a Snapdragon 8 Gen 5 for the X300 FE. These chipset names establish the hardware tiers on paper, not real-world speed, heat or sustained performance.
Screen size versus body size
Both cited Redmi variants have a 6.77-inch display. vivo’s Singapore specification gives the X300 FE compact body dimensions of 150.83 × 71.76 × 7.99mm and a weight of 191g; the India SKU’s exact weight should be confirmed locally. If you prefer a smaller handset, the published vivo dimensions are a useful point of comparison, but screen diagonal and body size are different measurements.

Camera layouts and storage
The cited Redmi 4G model pairs its 108MP main camera with a 2MP depth camera; the UK 5G model instead lists an 8MP ultra-wide camera and 4K/30fps video. vivo’s India launch announcement describes a 50MP ZEISS main camera and a 50MP ZEISS super-telephoto camera, with support for the ZEISS Telephoto Extender Gen 2. Its zoom and framing figures are vivo’s claims, not proof of equivalent results in independent testing. The vivo has no expandable storage, while Xiaomi’s regional pages list microSD expansion with different maximum capacities.
Battery, charging and protection
On published typical capacities, the vivo lists 6500mAh, compared with 6000mAh for the Mexico Redmi 4G and 5520mAh for the UK Redmi 5G. Capacity and charging wattage alone do not establish battery life or charging time. For ingress protection, the Mexico Redmi page lists IP64 and vivo India lists IP68/IP69. These are stated ratings, not a promise that a device is waterproof; the UK Redmi rating should be checked against the exact SKU before purchase.

Price difference: India snapshots are not a like-for-like quote
The available vivo figures are for India and refer to different dates, configurations or store snapshots. They should not be collapsed into one “current” price or compared as if they were a single unchanged offer.

Because the Redmi market and price are unspecified, a numerical price gap would be misleading. For a useful local comparison, match country, network version, RAM/storage, seller type and date; then compare the Redmi’s official or clearly identified retailer price with the same basis for the vivo.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Which one should you choose?
- Consider the Redmi Note 15 4G if the Mexico-listed configuration is the one sold in your market and you want its listed 6.77-inch AMOLED display, 6000mAh typical battery, microSD support or 33W charging. It is not the 5G model.
- Consider the Redmi Note 15 5G if you need 5G and the UK-listed configuration is available and compatible where you live. Its listed camera setup, chipset, battery and charger inclusion differ from the 4G version.
- Consider the vivo X300 FE if you want its compact published body dimensions, Snapdragon 8 Gen 5, higher listed charging wattage and dedicated telephoto camera system. Those are specification-sheet distinctions; real performance and camera quality require independent testing.
Before buying, verify the exact regional model, supported network bands, warranty, storage configuration, ingress rating, adapter and other box contents, and current local price. The vivo’s supported ZEISS Telephoto Extender Gen 2 is a separate accessory; check compatibility, local availability and price if it matters to your camera plans.
