The realme 15 Pro 5G is the better fit if you want a large, fast-refreshing screen and a higher stated battery capacity. The vivo X300 FE is smaller and lists a higher-tier processor plus a stabilized telephoto camera. In India, vivo’s store showed its 12GB+256GB X300 FE at ₹94,999 on October 7, 2026; the ₹33,999 realme figure is a third-party listing, so the available prices do not establish a reliable like-for-like gap.

Which phone has the better display?
The realme 15 Pro has the larger panel and higher maximum refresh rate: 6.8 inches and up to 144Hz, compared with the X300 FE’s 6.31-inch AMOLED display at 120Hz. That makes realme the more natural choice for a large viewing area and extra refresh headroom. The vivo’s smaller screen is the practical alternative if a more compact phone matters more than screen size.

The listed specifications put the X300 FE ahead on processor tier: Snapdragon 8 Gen 5, manufactured on a 3nm process and specified up to 3.8GHz, versus the realme’s Snapdragon 7 Gen 4, 4nm and up to 2.8GHz. These are manufacturer specifications, not comparable benchmark results; they do not by themselves establish how much faster one phone feels in particular apps or games. vivo’s India specifications and realme’s Singapore specifications provide the listed details.

How do the cameras differ?
The clearest hardware distinction is the vivo’s dedicated 50MP OIS telephoto camera, alongside its 50MP OIS main camera and 8MP wide-angle camera. realme’s Singapore specification lists a 50MP Sony IMX896 main camera and a 50MP ultra-wide camera. The telephoto gives the vivo a distinct camera option for zoom framing, but megapixel counts alone cannot determine which phone takes better photos.
Which has the larger battery, and which charges faster?
The 91mobiles comparison lists a 7000mAh battery and 80W wired charging for the realme 15 Pro. vivo specifies 6500mAh typical and 90W FlashCharge for the X300 FE; its India store specifies use of the original charger and cable for 90W charging. The listed capacity favors realme, while the vivo has the higher charging-wattage figure. Neither capacity nor wattage alone establishes actual endurance or charging time.

What is the price difference in India?
There is no confirmed apples-to-apples price difference in the available listings. On October 7, 2026, vivo’s India store showed the X300 FE in Lilac Purple with 12GB+256GB storage for ₹94,999, against an MRP of ₹119,999. Separately, 91mobiles listed ₹33,999 for the realme 15 Pro 5G and ₹94,999 for the X300 FE, labeling both with Amazon listings. The comparison page does not confirm that the realme price is for a matching memory configuration or that it is realme India’s current official price. Treat these as reported amounts, not a definitive price gap. Check the vivo India Store listing and 91mobiles’ comparison listing for the cited figures.
