The vivo X300 FE and Xiaomi Redmi Note 15 SE 5G target different priorities: vivo lists a smaller 6.31-inch phone with a Snapdragon 8 Gen 5 and three rear cameras, while Xiaomi lists a larger 6.77-inch phone with a Snapdragon 6 Gen 3 and a simpler two-camera setup. The price gap cannot be stated reliably from the available official listings: vivo has dated launch and store prices, but Xiaomi’s reviewed pages do not establish a live checkout price.

Specifications are manufacturer claims; they do not establish the same outcome in independent testing. In particular, listed peak-brightness figures may use different measurement methods, and battery capacity alone cannot show which phone lasts longer in everyday use. The chipset and storage standards indicate different hardware tiers on paper, but do not substitute for comparable benchmark tests.

How the size and screen change the experience
The most immediate distinction is physical size. vivo’s 6.31-inch display and 71.76mm width make the X300 FE the more compact option on the listed dimensions. The Redmi’s 6.77-inch curved screen gives more display area, while its listed weight is lower: 178g for black and white models, or 182g for Crimson, compared with 191g for the vivo.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsThat makes this a trade-off rather than a simple lighter-versus-heavier comparison: the Xiaomi is larger yet lighter according to the manufacturers’ specifications. The screen resolution and refresh-rate figures are close in purpose, but brightness values are not a controlled head-to-head result.

Camera hardware: telephoto versatility versus a basic depth camera
The rear camera arrangements differ more than the headline main-camera resolution suggests. vivo lists a stabilized 50MP main camera, a stabilized 50MP telephoto camera and an 8MP wide camera. That gives the X300 FE dedicated telephoto and wide-angle options on paper. Xiaomi lists a 50MP main camera alongside a 2MP depth camera, rather than a dedicated telephoto or wide rear camera.
For selfies, vivo lists a 50MP autofocus camera and Xiaomi a 20MP front camera. Those specifications describe resolution and configuration, not actual image quality; sensor performance, processing and shooting conditions also matter. No independent comparative camera results are established here.

vivo also announced a separate ZEISS Telephoto Extender Gen 2 accessory for the X300 FE. At launch on May 14, 2026, vivo listed it at ₹15,999 and said it was sold separately and compatible only with the X300 FE. Check current retailer availability and terms before treating that launch price as current.
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Battery capacity and charging
vivo lists a 6500mAh typical battery (6350mAh rated minimum) and 90W FlashCharge, with the maximum charging support dependent on use of the original charger and cable. Xiaomi lists a 5800mAh typical battery and 45W Turbo Charging, with a charger in the box. These figures show a larger stated capacity and higher stated charging rate for the vivo, but do not prove a runtime difference: display use, network conditions, software and other factors affect endurance.

What is the price difference?
A precise current price gap is not established by the official listings reviewed. vivo’s launch prices and a later store snapshot differ, while Xiaomi’s product and specification pages do not provide a verified live purchase price. The Xiaomi product page’s “under ₹20K” positioning is not an exact checkout price.
| Phone and price basis | Price | What the figure means |
|---|---|---|
| vivo X300 FE, launch price announced May 14, 2026 | ₹79,999 for 12GB+256GB; ₹89,999 for 12GB+512GB | Launch prices announced by vivo India; launch offers had eligibility and time limits. |
| vivo X300 FE, official store snapshot accessed October 7, 2026 | ₹94,999 displayed for a selected Lilac Purple 12GB+256GB configuration; MRP ₹119,999 | A dated listing snapshot, not the launch price or a guaranteed current price. |
| Xiaomi Redmi Note 15 SE 5G | Current price not established | The reviewed official product and specification pages did not confirm a live checkout price. |
To calculate a useful difference, compare listings checked on the same day and match storage configurations as closely as possible. Include only offers you qualify for, such as bank discounts or exchange deals; otherwise the apparent gap may not reflect what you would actually pay.

Which phone fits which priorities?
Choose the vivo X300 FE if you want
- A smaller display and more compact listed dimensions.
- The higher-tier processor and newer memory and storage standards stated by vivo.
- Dedicated telephoto and wide rear camera options, plus a high-resolution autofocus front camera.
- A higher listed charging rate and larger typical battery capacity.
- The update support periods stated by vivo.
Consider the Redmi Note 15 SE 5G if you want
- A substantially larger curved display.
- A lower listed weight, depending on the colour variant.

Neither specification sheet establishes which phone is faster in a specific workload, takes better photos, or lasts longer per charge. Those questions require comparable testing; choose based on the features that matter to you, and verify current prices and availability before buying.
