The realme 15T 5G and vivo X300 FE are in very different price and hardware tiers in India. The realme is the lower-priced option in its dated promotional listing, with a larger 120 Hz screen; the vivo has a smaller, higher-resolution display, a higher-tier listed chipset and a dedicated telephoto camera. Their published prices are not matched live offers, so they do not establish an exact current price gap.
India price difference: compare the same variant and offer type
Official India announcements show a substantial difference in their published price points, but the figures come from different sources and dates. realme’s Big Diwali Sale 2025 page advertised the 15T 5G “From ₹18,999*”. That is a promotional starting price, not evidence of a permanent price or the price of every configuration.

vivo’s 2026 launch announcement listed the X300 FE at INR 79,999 for 12 GB + 256 GB and INR 89,999 for 12 GB + 512 GB, inclusive of taxes. A later announcement listed an 8 GB + 256 GB version at INR 84,999, available from 12 August 2026. These are launch-announcement prices, not a current checkout check. See vivo’s India launch announcement for the dated figures.

Specifications are from the manufacturers’ pages: realme 15T 5G specifications, vivo X300 FE specifications and the vivo X300 FE product page. A feature not stated in the cited realme extract should not be treated as proof that the phone lacks it.
Performance: two different chipset tiers on paper
realme lists the Dimensity 6400 Max 5G, manufactured on a 6 nm process, while vivo lists the Snapdragon 8 Gen 5 on a 3 nm process. Those specifications place the phones in different hardware tiers on paper, but they do not quantify real-world speed. No directly comparable benchmark or independent test is established here, so choose based on the documented hardware rather than an assumed score or gaming result.

Screen: larger viewing area or more pixels in a compact size?
The realme’s 6.57-inch panel is physically larger than the vivo’s 6.31-inch display. Both manufacturers list refresh rates up to 120 Hz, while vivo’s listed resolution of 2640 × 1216 is higher than realme’s 1080 × 2372. The listed peak-brightness figures—up to 4000 nits for realme and 5000 nits local peak for vivo—may use different methods or conditions, so they are not a controlled brightness comparison.
Cameras: telephoto flexibility is the key hardware distinction
Both phones have a listed 50 MP front camera, though vivo specifies autofocus. On the rear, realme lists a 50 MP main camera plus a 2 MP monochrome portrait camera. vivo lists a 50 MP autofocus/OIS main camera, a separate 50 MP OIS telephoto camera and an 8 MP fixed-focus wide-angle camera. That gives the vivo more listed focal-length options, particularly for telephoto framing; megapixel counts alone do not establish which phone takes better photographs.

vivo also announced a compatible ZEISS Telephoto Extender Gen 2 for the X300 FE. It is an optional, separately purchased accessory, priced at INR 15,999 inclusive of taxes in the 2026 launch announcement. It is not a shared accessory for both phones.

vivo lists a 6500 mAh typical battery (6350 mAh rated minimum), up to 90 W wired charging, and promotes 40 W wireless charging on its product page. The cited realme specifications extract does not expose numerical battery or charging values, so there is no sound capacity or endurance comparison to make from these figures. Battery size and charging wattage also do not establish actual screen-on time or charging duration.
