There is no dependable, like-for-like price difference to report yet: the comparison sources disagree about whether the OPPO K15 Pro has launched, and their displayed prices do not establish current offers in the same market. Their listed specifications suggest a clear tradeoff: the vivo X300 FE is smaller and adds a telephoto camera and wireless charging, while the K15 Pro is listed with a larger, faster-refreshing display and a higher-capacity battery. Treat these as third-party listings, not confirmed regional specifications.
Availability and price: what the listings actually establish
As of October 4, 2026, the available third-party pages do not settle whether the OPPO K15 Pro is on sale. 91mobiles’ comparison page labels the K15 Pro “Upcoming” and says it is not available in any store. Mobolist’s comparison, by contrast, asserts an April 1, 2026 launch date and provides product prices. The sources do not explain the discrepancy, so neither a launch date nor local retail availability is confirmed here.

The price figures are also not a valid direct comparison. 91mobiles displays ₹86,999 at Amazon for the vivo X300 FE and no store availability for the K15 Pro. Mobolist lists worldwide prices of $847 for the vivo 12 GB/256 GB configuration and $953 for 12 GB/512 GB, versus $465 and $508 for the OPPO’s respective 12 GB/256 GB and 12 GB/512 GB configurations. The pages do not establish matching markets, capture dates, taxes, active stock, or equivalent regional SKUs. These figures are listing signals, not verified current prices; subtracting them would produce a misleading price difference.

The table summarizes figures reported by 91mobiles, not independently confirmed regional manufacturer specifications. “Not listed” means the comparison page does not provide the detail; it does not prove a feature is absent.

Display: smaller phone or larger, smoother panel?
The listing makes the vivo the more compact choice: its screen is reported at 6.31 inches, compared with 6.59 inches for the OPPO. That size difference may matter if you prefer a phone that is easier to handle, but dimensions and weight are not supplied here, so screen size alone cannot establish which device feels smaller overall.
The K15 Pro is listed at 144 Hz against the vivo’s 120 Hz. A higher refresh-rate specification can allow supported content and interface animations to update more often, but it does not by itself establish better image quality or a smoother experience in every app. The panel types and resolutions are reported as AMOLED, 1216 × 2640 for vivo and OLED, 1256 × 2760 for OPPO. The comparison provides no independent display-quality measurements.

Cameras: vivo has a listed telephoto lens
On paper, the key hardware difference is the third rear camera in the vivo listing: a 50 MP telephoto module alongside a 50 MP main and 8 MP ultrawide. The OPPO listing has a 50 MP main camera and an 8 MP ultrawide, with no telephoto camera shown. A dedicated telephoto camera can offer a separate focal length for zoomed shots, but these specifications do not establish zoom range or image quality.

Battery and charging: capacity is not tested endurance
The K15 Pro is listed with a 7,500 mAh battery, compared with 6,500 mAh for the vivo. That is a larger stated capacity for OPPO, but it is not evidence of longer real-world battery life: screen size, chipset efficiency, software, and usage affect endurance, and no comparable battery test is supplied.
The listed wired charging rates are 80 W for OPPO and 90 W for vivo. The vivo page also lists wireless charging, while the OPPO page lists it as absent. These are specification-page claims; confirm charging standards, compatible accessories, and regional product details before relying on them.

- Precise cut-outs, just like the real thing: moulded to match the actual device, with buttons, cameras and charging ports perfectly aligned; the buttons offer crisp, responsive feedback; the full-coverage design doesn’t interfere with the screen, ensuring a comfortable grip and replicating the feel of using the device without a case.
- High-quality materials, durable and easy to clean: Made from eco-friendly PC+TPU composite material, it is flexible, resistant to deformation and wear-resistant; the surface is water- and oil-repellent, so stains wipe away easily, keeping it looking as good as new even after prolonged use.
Performance and storage: no fair speed verdict
The comparison lists a Snapdragon 8 Gen 5 in the vivo and a MediaTek Dimensity 8500 in the OPPO, but it does not provide enough evidence to name a performance winner. Its 3,000,897 AnTuTu score for the vivo has no matching K15 Pro result. The score is therefore not a head-to-head benchmark, and the comparison does not state test conditions.

What to verify before choosing
Because availability and price are unsettled, first check official regional product information and a live retailer listing for the exact model. If both phones can be bought where you live, compare:
Quick Recap
- The total price for equivalent RAM and storage, including taxes and any delivery charges.
- Official regional specifications, including display protection, water-resistance rating, charging support, and the exact camera configuration.
- Independent camera reviews and comparable battery-endurance tests rather than relying on megapixels or battery capacity alone.
- Software-update commitments, warranty coverage, SIM support, and network-band compatibility for your region.
- Whether the specific retailer actually has the configuration in stock and can provide local after-sales support.
