The vivo X300 FE is the compact, higher-spec option on paper; the Xiaomi Redmi 15A 5G is built around a larger screen and a lower price tier. The X300 FE stands out for its AMOLED display, listed Snapdragon 8 Gen 5 chipset, telephoto camera and 90W charging. The Redmi offers a 6.9-inch 120Hz display and a stated four-OS-update, six-year security-update commitment. The exact price difference is not established by a like-for-like current listing: vivo’s India store showed ₹94,999 for one X300 FE configuration, while a third-party comparison displayed different prices for both phones. Check current India retailer offers and matching variants before buying.

How the screens and size differ

X300 FE: smaller AMOLED screen

At 6.31 inches, the X300 FE is the more compact choice of the two. Its AMOLED panel has a listed 2640 × 1216 resolution, which gives it a substantially higher pixel count than the Redmi’s resolution reported by 91mobiles. This combination may suit buyers who prefer a smaller phone and prioritize a sharper-looking display, though screen quality also depends on factors beyond resolution.

Redmi 15A 5G: larger 120Hz display

The Redmi’s 6.9-inch screen gives more room for reading, video, and large on-screen controls. Xiaomi lists a 120Hz refresh rate but does not state the panel type or resolution on the retrieved product page; 91mobiles identifies it as a 720 × 1600 IPS LCD. Choose the larger screen for viewing area rather than assuming it matches the X300 FE’s display sharpness or panel characteristics.

Performance and memory

vivo lists the X300 FE with a Snapdragon 8 Gen 5 and up to 12GB of RAM and 512GB of storage. The Redmi’s Unisoc T8300 and 4GB/64GB configuration come from 91mobiles’ comparison snapshot, not a comprehensive Xiaomi variant catalog. These specifications position the X300 FE as the more ambitious hardware option on paper, but the available evidence does not establish a measured head-to-head performance gap. Do not treat the Redmi configuration shown by the comparison site as the only variant sold in India.

Camera systems: telephoto versus basic dual-camera listing

The X300 FE has a more versatile specified rear-camera arrangement: a 50MP main camera with autofocus and optical image stabilization (OIS), a separate 50MP OIS telephoto camera, and an 8MP fixed-focus wide-angle camera. Its 50MP front camera also has autofocus, according to vivo’s store specification.

Xiaomi describes the Redmi 15A 5G’s rear setup as a 32MP AI dual camera and lists an 8MP front camera. The published details here do not establish equivalent telephoto hardware or OIS for the Redmi. Megapixel counts alone do not predict photo quality, so these specifications are best used to understand camera flexibility—not to assume how either phone performs in real-world photos.

Battery capacity, charging, and durability

The X300 FE is rated at 6500mAh typical capacity and 6350mAh minimum rated capacity. vivo lists up to 90W FlashCharge when using the original adapter and cable. Xiaomi lists a 6300mAh battery, 15W wired charging, and 7.5W reverse charging for the Redmi 15A 5G. These capacity and charging figures do not establish comparative battery life; actual endurance depends on use and other conditions.

For ingress protection, vivo lists IP68 and IP69 laboratory ratings, while Xiaomi lists IP52. vivo cautions that resistance is not permanent, the phone is not a professional water-resistant device, and liquid damage is not covered by warranty. An IP rating should not be read as permission to deliberately expose either phone to water or dust.

Software support: Redmi has the clearer published commitment

Xiaomi states that the Redmi 15A 5G will receive four OS updates and six years of security updates. The retrieved vivo India specification page identifies Android 16 and OriginOS 6 for the X300 FE but does not state an equivalent support duration. That makes the Redmi’s support promise clearer in the available product information; it does not establish how long vivo will support the X300 FE.

Price difference in India: verify matching offers

The exact current price gap cannot be responsibly calculated from the available figures because they are not a matched comparison. vivo’s India store displayed ₹94,999 for the X300 FE 12GB + 256GB configuration. Separately, 91mobiles’ comparison view displayed ₹89,999 for the X300 FE and ₹15,120 for the Redmi 15A 5G, prices it identified as Amazon prices. Those third-party snapshots imply a ₹74,879 difference, but the X300 FE figure differs from vivo’s store listing and Xiaomi’s official current price was not established. Treat them as dated snapshots, not a definitive price comparison.

Before checkout, compare the same date and country, confirm each phone’s RAM and storage configuration, and check whether a displayed figure is an official list price or a retailer offer. Use the vivo India store listing and Xiaomi India product page alongside authorized retailers to verify current price, stock, and variant.

Which phone should I buy?

Choose the vivo X300 FE if

  • You want a smaller 6.31-inch phone with an AMOLED display.
  • You value the higher-end chipset and memory/storage options vivo lists.
  • A dedicated telephoto camera, OIS on the main and telephoto cameras, or autofocus selfie camera matters to you.
  • You prioritize faster listed charging and the higher ingress-protection ratings, while understanding vivo’s water-resistance and warranty caveats.
  • The current price for the configuration you want fits your budget.

Consider the Redmi 15A 5G if

  • You prefer a much larger 6.9-inch screen with a 120Hz refresh rate.
  • You are shopping in a lower price tier and confirm a suitable current offer and available memory configuration.
  • Xiaomi’s stated four OS updates and six years of security updates are important to your purchase decision.
  • The listed basic camera and charging specifications meet your needs.

For a purchase decision, compare the actual listings for the exact variants you can buy: an unverified Redmi price or memory configuration can make a nominal price gap misleading.
