The realme P3 Pro is the larger-screen, lower-priced option in the available listings; the vivo X300 FE is more compact and has a higher-tier listed chipset, a dedicated OIS telephoto camera and wireless charging. The price figures are not a like-for-like comparison: the P3 Pro amount is a dated Amazon India price, while vivo’s is for a specific 12GB+256GB variant on its official store.

Which phone has the better screen and form factor?
The P3 Pro’s 6.83-inch display is the choice for buyers who want more screen area for video, games or reading. realme describes it as a 1.5K, 120Hz quad-curved panel. The X300 FE is the compact-screen alternative: its 6.31-inch AMOLED panel has a stated resolution of 2640 × 1216 and a 120Hz refresh rate. Screen size alone does not establish which display looks better; the available specifications do not provide a comparable brightness or display-quality test.

realme lists the Snapdragon 7s Gen 3 on a 4nm process for the P3 Pro, while vivo lists the Snapdragon 8 Gen 5 on a 3nm process for the X300 FE. The vivo chip is the higher-tier chipset in the manufacturers’ specifications, but process node and product tier do not establish a precise real-world speed difference. No comparable independent benchmark is available here.

For the P3 Pro, realme also lists a 6050mm² vapor-chamber cooling area and claims support for 90fps BGMI. Its product page reports an AnTuTu score of “800,000+”; both the game-support statement and score are vendor claims, not independent test results. They should not be read as a guarantee of sustained frame rate or as a direct benchmark comparison with the X300 FE.
Battery capacity and charging
On manufacturer-rated capacity, the X300 FE lists a larger battery: 6500mAh typical and 6350mAh rated, versus 6000mAh typical and 5860mAh rated for the P3 Pro. realme specifies 80W charging; vivo specifies 90W wired charging and advertises 40W wireless FlashCharge. Capacity and charging wattage do not by themselves establish battery life or charging time in everyday use.

Which phone has the more versatile camera system?
vivo gives the X300 FE a clearly stated three-camera rear setup: a 50MP OIS main camera, 50MP OIS telephoto camera and 8MP fixed-focus wide-angle camera. It also lists a 50MP autofocus front camera. That dedicated telephoto camera makes the X300 FE the more versatile choice on the specifications provided, especially for buyers who want an optical zoom camera rather than relying only on the main camera.

Water and dust protection ratings
realme advertises IP69 protection for the P3 Pro; vivo lists IP68 and IP69 for the X300 FE. These are manufacturer-stated ratings. They do not establish that either phone is damage-proof or that liquid damage is covered by warranty; check each manufacturer’s terms for coverage and care guidance.
India price difference: what the listings actually show
| Phone and configuration | Listed price | Source and date |
|---|---|---|
| realme P3 Pro; configuration not specified in the cited listing | ₹20,995 lowest Amazon India price reported | Gadgets 360 listing dated September 11, 2026 |
| vivo X300 FE, 12GB+256GB | ₹89,999; listed MRP ₹119,999 | vivo Official E-Store India, retrieved October 4, 2026 |
Subtracting the quoted amounts gives ₹69,004, but that is only an indicative contrast, not a current like-for-like price gap: the listings are different types, the P3 Pro configuration is unspecified, and its reported price is a historical snapshot that may no longer be available. Check live prices, seller, offers and equivalent RAM and storage variants before buying.

Which one should you choose?
- Choose the realme P3 Pro if you prioritize a larger 6.83-inch display, realme’s gaming-oriented cooling features, and the lower dated price listing—after confirming today’s price and configuration.
- Choose the vivo X300 FE if you want a smaller 6.31-inch phone, the higher-tier chipset listed by its manufacturer, a dedicated OIS telephoto camera, or wireless charging.
These are trade-offs drawn from published specifications, not a hands-on performance verdict. The better fit depends on which features matter most and on current prices for equivalent configurations.
