The iQOO 15R has the larger listed display at 6.59 inches, compared with 6.31 inches on the X300. The comparison listing gives the iQOO a 130Hz rate in normal scenes. A larger panel or higher stated refresh rate alone does not establish which screen looks better; the cited specifications do not provide a controlled display-quality comparison.

Camera hardware: X300 adds a dedicated telephoto
The X300’s listed rear setup includes a stabilized 200MP main camera, an autofocus ultrawide and a stabilized 3x optical telephoto. The iQOO 15R listing gives a 50MP Sony main camera and an 8MP ultrawide, with no dedicated telephoto listed. That gives the X300 more stated focal-length flexibility, especially for optical zoom. It does not establish better real-world photos: no independent camera tests were available for this comparison.
Battery capacity and charging
On paper, the iQOO 15R leads in both listed figures: its typical capacity is 7600mAh and its wired charging rating is 100W, versus 6040mAh typical and 90W FlashCharge for the X300. These are manufacturer specifications, not measured battery endurance or charge-time results, so they cannot tell you exactly how long either phone lasts or takes to charge in your use.
Processor and configurations
The X300 is listed with a MediaTek Dimensity 9500, while the iQOO 15R uses a Snapdragon 8 Gen 5. Chip names by themselves do not show which phone performs better in gaming, sustained workloads, thermals or everyday use; there are no independent comparative benchmarks in the cited material.

| Phone and configuration | Official-store listing price | Price context |
|---|---|---|
| vivo X300, 12GB+256GB | ₹83,999 | vivo Store India listing accessed October 7, 2026 |
| vivo X300, 12GB+512GB | ₹89,999 | vivo Store India listing accessed October 7, 2026 |
| iQOO 15R, 8GB+256GB | ₹53,999 | vivo Store India comparison listing accessed October 7, 2026 |
The X300 12GB+256GB listing is ₹30,000 above the iQOO 15R 8GB+256GB listing. Because the X300 configuration has 4GB more RAM, this is not a like-for-like price comparison. The cited prices are snapshots surfaced in official-store listings, not guaranteed current checkout prices or Amazon prices; verify the exact variant, stock and offers with the seller before buying.
Which phone fits your priorities?
Choose the vivo X300 if
- You want a more compact listed screen size.
- A dedicated 3x optical telephoto and the listed three-camera rear setup matter to you.
- You prefer to compare configurations that include 12GB or 16GB RAM.
Consider the iQOO 15R if
- You want the larger listed display.
- The larger stated battery capacity and 100W charging rating are priorities on paper.
- The cited 8GB+256GB official-store listing is closer to your budget, subject to current availability and price.
The official listings establish specifications and price snapshots, not measured camera quality, battery life, gaming performance, thermals, software smoothness or long-term reliability. There is no evidence here for a universal performance or overall-value winner; your choice depends on the feature and configuration you value, plus current seller pricing.
