The listed specs suggest a compact-screen, telephoto-camera and wireless-charging advantage for the vivo X300 FE, while the OPPO K15 Pro listing has a larger, faster-refreshing display and higher battery capacity. Treat these as third-party listings, not confirmed regional specifications.
Availability and price: the comparison is not settled
As of October 4, 2026, the available third-party listings disagree about whether both phones can be bought. 91mobiles’ comparison labels the vivo X300 FE released, with a May 6, 2026 launch date, but marks the OPPO K15 Pro as upcoming and unavailable in stores. Mobolist’s comparison asserts April 16, 2026 for the vivo and April 1, 2026 for the OPPO. Neither page resolves the discrepancy or establishes official regional availability.
The displayed prices are also not a like-for-like, live quote. 91mobiles shows ₹86,999 at Amazon for the vivo X300 FE and no store availability for the OPPO. Mobolist lists worldwide prices of $847 for the vivo 12 GB/256 GB and $953 for its 12 GB/512 GB version, versus $465 and $508 for the OPPO in those respective configurations. These are third-party listing figures with unclear capture dates; they do not establish official launch prices, current offers, taxes, market, stock, or equivalent SKUs. Subtracting them would not produce a reliable price difference.

Display: smaller vivo screen, higher OPPO refresh rate
On the comparison page, the X300 FE’s 6.31-inch display is the smaller option, while the K15 Pro’s 6.59-inch panel is listed at 144 Hz rather than 120 Hz. The OPPO listing therefore points to more screen area and a higher refresh rate; those labels alone do not establish brightness, color accuracy, outdoor visibility, or overall display quality.

Cameras: a listed telephoto option on the vivo
The listed rear-camera configurations differ in a practical way: the vivo has a dedicated 50 MP telephoto camera in addition to its main and ultrawide cameras, while the OPPO listing has a 50 MP main and an 8 MP ultrawide. The page also lists 50 MP front resolution for vivo and 16 MP for OPPO. Megapixel counts do not demonstrate image quality, zoom performance, or low-light results, and the comparison provides no camera testing to settle those questions.
Battery and charging: capacity is not endurance
The 91mobiles specifications give the OPPO a stated 7,500 mAh capacity against 6,500 mAh for the vivo, while listing 80 W wired charging for the OPPO and 90 W for the vivo. It lists wireless charging for vivo and not for OPPO. Capacity and charging wattage alone cannot predict real-world battery life or charging time; no comparable endurance or charging test is provided.

Performance: no fair head-to-head result
The comparison lists a Snapdragon 8 Gen 5 in the vivo and a MediaTek Dimensity 8500 in the OPPO. It shows an AnTuTu score of 3,000,897 for the vivo but provides no corresponding K15 Pro score. That one-sided figure is not a controlled comparison, so it cannot establish which phone performs faster.

There is not enough confirmed information here to name an overall winner. If both models are officially available where you live, compare exact RAM and storage configurations and live prices, then weigh screen size and refresh rate against the vivo’s listed telephoto camera and wireless charging. For battery-life or performance decisions, look for comparable testing rather than inferring a winner from capacity, chipset names, or an unmatched benchmark.
