Which phone has the more versatile camera hardware?
The clearest hardware difference is the X300 FE’s dedicated 50MP OIS telephoto camera, alongside a 50MP OIS main camera and an 8MP wide-angle camera. The realme Singapore specification page lists a 50MP Sony IMX896 main camera and a 50MP ultra-wide camera. A telephoto camera gives the vivo a distinct camera option, but megapixel counts and stabilization labels alone cannot determine which phone takes better photos. vivo’s India specifications; realme’s Singapore specifications.
Which has the larger battery, and which charges faster on paper?
91mobiles lists a 7000mAh battery and 80W wired charging for the realme 15 Pro. vivo lists the X300 FE at 6500mAh typical capacity with 90W FlashCharge, and its India store says to use the original charger and cable. The realme therefore has the larger stated capacity, while the vivo has the higher listed charging wattage. Neither capacity nor wattage alone proves longer real-world battery life or a specific charging time.

What is the price difference in India?
As accessed on October 7, 2026, vivo India’s store showed the X300 FE in Lilac Purple with 12GB+256GB storage at ₹94,999, against an MRP of ₹119,999. 91mobiles listed ₹33,999 for the realme 15 Pro 5G and ₹94,999 for the X300 FE, labeling both with Amazon listings. The 91mobiles figures do not establish matched storage variants, and the realme amount is not confirmed as its current official India price. vivo India store listing; 91mobiles comparison listing.
So, the listed figures differ by ₹61,000, but that arithmetic is not a reliable like-for-like price gap.
