iQOO also adds a color-changing rear panel option on the gray variant, giving it a more unique and futuristic appearance.
Users who prefer compact flagship phones will likely enjoy the Vivo X300 FE more, while users wanting a larger premium device may prefer the iQOO 15.

The iQOO 15 clearly delivers a more premium multimedia and gaming experience thanks to its sharper resolution, faster refresh rate, and larger screen size.
However, the Vivo X300 FE still offers an excellent display experience for users who prefer compact devices without sacrificing flagship quality.
For gaming and entertainment, iQOO 15 has the clear advantage.
Performance and Software
Performance is one of the biggest differences between these smartphones.
The Vivo X300 FE runs on the Snapdragon 8 Gen 5 chipset paired with the Adreno 829 GPU. It delivers flagship-level gaming and multitasking performance while maintaining strong battery efficiency.
The iQOO 15 uses the more powerful Snapdragon 8 Elite Gen 5 processor with the Adreno 840 GPU. It offers significantly higher CPU and GPU performance, making it one of the fastest Android phones currently available.
Both devices run Android 16 with OriginOS 6 and promise up to five major Android upgrades.

The iQOO 15 features:
- 50MP primary sensor
- 50MP periscope telephoto camera
- 50MP ultrawide camera
