The realme P3 Pro is the larger-screen, lower-priced-on-a-dated-listing option; the vivo X300 FE is more compact and adds a higher-tier listed chipset, a stabilized telephoto camera and wireless charging. They suit different priorities, and the available India price figures are not a like-for-like comparison.
realme P3 Pro vs vivo X300 FE specifications
The figures below are manufacturer specifications for India-market models, except where a price source is identified. Specifications can vary by region and configuration.
| Specification | realme P3 Pro 5G | vivo X300 FE |
|---|---|---|
| Display | 6.83-inch 1.5K, 120Hz quad-curved display (realme) | 6.31-inch AMOLED, 2640 × 1216, 120Hz (vivo) |

How the screen size and design affect the choice
The P3 Pro’s 6.83-inch quad-curved display gives it the larger viewing area on paper, which may suit buyers who prefer more screen space for games, video and reading. The X300 FE’s 6.31-inch display makes it the compact-screen choice between these two. Display size alone does not establish how comfortable either phone feels in hand; that also depends on dimensions, weight and personal preference.

Performance: a higher listed chipset tier on vivo
realme specifies the Snapdragon 7s Gen 3 on a 4nm process, while vivo specifies the Snapdragon 8 Gen 5 on 3nm. These are different chipset tiers, but the process figures do not establish a precise real-world speed advantage. No comparable independent benchmark evidence is available here, so do not treat vendor performance figures as a direct head-to-head test.

realme advertises support for 90fps BGMI and reports an AnTuTu score of “800,000+” on its product page. Those are manufacturer claims, not independently verified comparative results; actual frame rates and performance depend on conditions and software.
Battery capacity and charging
vivo lists a larger typical battery capacity—6500mAh versus realme’s 6000mAh—and faster stated wired charging at 90W versus 80W. Both manufacturers also publish rated capacities below their typical figures: 6350mAh for vivo and 5860mAh for realme. Capacity and charging specifications do not establish which phone lasts longer in everyday use.

vivo also advertises 40W wireless FlashCharge for the X300 FE. The cited realme specification lists wired charging and does not establish wireless charging support.
Camera versatility
The X300 FE has a more fully specified rear-camera system: a 50MP OIS main camera, a 50MP OIS telephoto camera, and an 8MP fixed-focus wide-angle camera. Its front camera is listed as 50MP with autofocus. That gives the vivo a stated dedicated telephoto option; megapixel counts and stabilization specifications alone do not establish comparative image quality.

realme highlights a Sony IMX896 OIS camera for the P3 Pro, but the cited product material does not provide a complete, directly comparable camera specification set. vivo says its ZEISS Telephoto Extender Gen 2 is compatible with the X300 FE and is sold separately; it is an optional accessory, not an included camera feature.
Protection ratings
realme advertises IP69 for the P3 Pro; vivo lists both IP68 and IP69 for the X300 FE. These are manufacturer-listed ingress-protection ratings, not guarantees that a phone is damage-proof or that liquid damage will be covered by warranty. Check each brand’s regional warranty terms before relying on protection claims.

India price difference: the listed figures are not like for like
As retrieved on October 4, 2026, vivo’s official India store lists the X300 FE with 12GB+256GB at ₹89,999, against a listed MRP of ₹119,999. Gadgets 360 reported a lowest Amazon India price of ₹20,995 for the realme P3 Pro on September 11, 2026. That realme figure is a dated listing snapshot, not a guaranteed current offer.
Subtracting those two quoted prices gives ₹69,004, but this is only an indicative contrast: it compares different listing types, the realme price is historical, and the cited evidence does not establish matching memory and storage configurations. Check the live price, seller, offer conditions and exact variant for both phones before comparing what you would actually pay.

Which phone should you choose?
Choose the realme P3 Pro if
- You prefer a larger 6.83-inch display.
- You value realme’s stated gaming-oriented cooling hardware and its vendor-claimed BGMI support.
- The lower P3 Pro price listing is relevant to your budget, after confirming the current price and variant.
Choose the vivo X300 FE if
- You want the more compact 6.31-inch display.
- You prioritize the higher-tier chipset listed by its manufacturer, without assuming a particular benchmark or gaming outcome.
- You want a specified OIS telephoto camera, a 50MP autofocus front camera, or advertised wireless charging.
These are specification-based trade-offs, not conclusions from hands-on testing. The better fit depends on which features matter most and the current price of the exact configuration you plan to buy.
