The right comparison depends first on which Redmi Note 15 you mean: Xiaomi’s Mexico-listed 4G model and UK-listed 5G model have different chipsets, cameras, batteries, charging and network support. The available vivo X300 FE specifications and price information here are for India, so there is no reliable universal price difference to quote. The table compares those specific regional versions using manufacturer-published information, not hands-on performance tests.
Which Redmi Note 15 model are you comparing?
“Redmi Note 15” does not identify one worldwide specification. Xiaomi’s Mexico page describes a 4G model with a MediaTek Helio G100-Ultra, while its UK page describes a 5G model with a Snapdragon 6 Gen 3. Their camera, battery, charging and connectivity details also differ. Check the model name and full specifications on the local Xiaomi page before using either column below; regional network bands, NFC, accessories and other details can vary.
The vivo information below is India-specific. Its listed configurations and dated price snapshots should not be treated as prices or specifications for other countries.

What the specification differences mean
Chipset and network support
The two cited Redmi models are not equivalent network options: Mexico’s version is listed for 4G/3G/2G, while the UK model is a 5G phone. The vivo India page lists a Snapdragon 8 Gen 5. These names identify different chipsets, but specifications alone do not establish real-world speed, heat or sustained performance. Confirm the exact model’s bands and carrier compatibility before buying, particularly if importing a phone.

Screen size and handling
Both cited Redmi versions have a 6.77-inch display. Vivo’s Singapore specification gives the X300 FE a 150.83 × 71.76 × 7.99mm body, a compact form factor by the manufacturer’s positioning. The dimensions are from Singapore, not a confirmed India SKU measurement. If one-handed handling matters, compare the exact local units in person where possible; a display diagonal alone does not describe the whole phone’s feel.
Camera hardware
The Mexico Redmi’s listed rear setup pairs a 108MP main camera with a 2MP depth camera; the UK 5G model instead lists an 8MP ultra-wide alongside its 108MP main camera. Vivo’s India launch information describes a dedicated 50MP ZEISS super-telephoto camera as well as the main camera, and the company promotes compatibility with its Telephoto Extender Gen 2. Resolution and zoom-range claims do not by themselves establish photo quality. The cited material does not provide independently tested, comparable camera results.

Battery, charging and durability
On paper, the Mexico Redmi has a 6000mAh typical battery and 33W charging, while the UK 5G Redmi lists 5520mAh typical and 45W. Vivo India lists 6500mAh typical capacity and 90W FlashCharge. Capacity and charging wattage are not battery-life or charging-time tests; actual results depend on usage, charger, conditions and software. For ingress protection, the available ratings are also not identical: Xiaomi Mexico lists IP64 and vivo India lists IP68/IP69. An IP rating is not a promise that a phone is waterproof or immune to damage.
What is the price difference?
There is no defensible single price difference from the available figures. The Redmi sources are regional specification pages without a matched official price for a specified configuration and date. The vivo figures are India snapshots for different storage variants and dates, so they cannot be compared fairly with an unspecified Redmi price or with one another as if they were the same offer.

For context, vivo’s India launch announcement lists ₹79,999 for the 12GB/256GB X300 FE and ₹89,999 for 12GB/512GB. A later announcement prices the 8GB/256GB version at ₹84,999 inclusive of taxes and says it was scheduled to be available from 12 August 2026. The India e-store pages displayed ₹89,999 and ₹99,999 respectively for the 12GB/256GB and 12GB/512GB listings at the cited snapshot. Store prices can change and may reflect an offer, color or SKU selection; check the listing directly before purchase.
To calculate a meaningful difference, compare the same country and purchase date, and match RAM/storage as closely as possible. Use the local Redmi 4G or 5G SKU—not simply the Redmi Note 15 name—and compare its current price with the corresponding X300 FE configuration, including taxes and any required charger. No numeric Redmi-versus-vivo price gap is established here.

Which phone should you choose?
- Consider the Redmi Note 15 4G if the Mexico-listed model’s 4G support, 6.77-inch screen, 6000mAh typical battery, microSD expansion or local price suits your needs. Verify the exact local SKU and its included adapter.
- Consider the Redmi Note 15 5G if you want the UK-listed variant’s 5G support and 8MP ultra-wide camera. Its chipset, battery, charging and bands differ from the 4G version, so confirm those details for your market.
- Consider the vivo X300 FE if you want the India-listed Snapdragon 8 Gen 5 platform, a smaller-bodied design by its published dimensions, higher listed charging wattage, and a dedicated telephoto camera. Treat those as specification advantages rather than proof of tested performance or image quality.
Before ordering any variant, check the exact model code, local warranty, supported carrier bands, RAM and storage, ingress rating, and what is in the box. For the X300 FE, verify the India SKU’s dimensions and weight if those affect your choice; the cited body measurements are from vivo Singapore.
