Vivo X300 FE and iQOO 15 take two very different approaches to the flagship smartphone experience. The Vivo focuses on premium design, compact usability, and camera refinement, while the iQOO 15 delivers aggressive performance, a larger battery, and stronger value for money. Here’s a detailed comparison of their design, performance, cameras, battery life, and pricing to see which flagship stands out. 

Major Features:

Design and Display

Build and Feel

The Vivo X300 FE focuses on a more compact flagship experience with a premium glass-and-metal construction that feels easier to handle during long usage sessions. Its cleaner proportions make one-handed use noticeably more comfortable, especially for users moving from smaller premium phones. The iQOO 15, meanwhile, takes a more aggressive flagship approach with a larger chassis, sharper styling, and even a color-changing rear panel option that gives it a more futuristic personality. Both devices offer IP68/IP69 protection and premium materials, but the Vivo feels more refined while the iQOO leans toward performance-centric styling.

Display Quality

Vivo equips the X300 FE with a bright LTPO AMOLED panel featuring 5000 nits peak brightness and excellent HDR tuning. The display looks vibrant without appearing overly saturated. The iQOO 15 counters with a sharper 2K LTPO AMOLED panel, a smoother 144Hz refresh rate, and stronger multimedia support through Dolby Vision and HDR Vivid. Gaming and video playback feel more immersive on the iQOO, while the Vivo offers a slightly more balanced and eye-friendly viewing experience.

Verdict

The Vivo X300 FE feels more practical and premium for daily comfort, but the iQOO 15 delivers a more impressive display experience overall.

Specifications Including Battery

Performance

The Vivo X300 FE runs on the Snapdragon 8 Gen 5 chipset paired with UFS 4.1 storage, delivering flagship-grade speed for gaming, multitasking, and AI-heavy features. Performance remains smooth and efficient, especially for users who prefer sustained thermal control over extreme benchmark numbers. The iQOO 15 pushes things further with the Snapdragon 8 Elite Gen 5 and a more aggressive CPU configuration. It is clearly built for maximum performance and high-refresh gaming, making it one of the faster Android phones in this segment. The additional RAM and 1TB storage option also give it more flexibility for power users.

Battery and Charging

Battery life is strong on both phones, but the iQOO 15 gains an advantage with its larger 7000mAh battery and faster 100W charging support. Heavy gamers and long-session users will appreciate the extra endurance. The Vivo X300 FE still performs impressively with its 6500mAh battery, 90W wired charging, wireless charging, and reverse charging features. Its charging speeds feel more than fast enough in daily use.

Verdict

The iQOO 15 wins on raw power and battery endurance, while the Vivo X300 FE feels more balanced and thermally controlled for everyday flagship usage.

Camera

Main and Secondary Lenses

The Vivo X300 FE places heavy focus on camera quality with Zeiss optics, refined image processing, and a versatile triple-camera setup. Its 50MP primary sensor captures natural colors with strong dynamic range, while the periscope telephoto lens produces detailed zoom shots with excellent stabilization. The optional Zeiss zoom accessory also adds a unique photography advantage rarely seen in mainstream flagships. Even the ultrawide camera maintains decent consistency in color science.

The iQOO 15 takes a more balanced hardware-first approach with three 50MP sensors, including a stronger ultrawide camera compared to the Vivo. Photos look sharp and punchy, and the phone handles video recording extremely well. However, the image tuning feels slightly more aggressive, especially in saturated lighting conditions.

Selfie Camera

The Vivo X300 FE clearly leads in selfie hardware with a 50MP autofocus front camera capable of sharper detail and more natural portrait separation. The iQOO 15’s 32MP selfie shooter performs well for casual use and video calls, but lacks the flagship-level refinement seen on the Vivo.

Verdict

The Vivo X300 FE delivers a better overall camera experience thanks to stronger tuning, Zeiss optimization, and a superior selfie system, while the iQOO 15 focuses more on consistency and versatility.

Pricing

The Vivo X300 FE is priced around $950 / ₹80,000, placing it firmly in the premium compact flagship category. Its pricing reflects the Zeiss camera partnership, premium build quality, wireless charging support, and refined software-camera optimization. It feels targeted toward buyers who prioritize camera quality and flagship polish over outright benchmark performance.

The iQOO 15 is priced around $600 / ₹73,000, making it surprisingly competitive considering the Snapdragon 8 Elite Gen 5 chipset, 2K 144Hz display, massive battery, and flagship-grade charging capabilities. It undercuts many premium rivals while still offering true ultra-flagship hardware. The pricing strategy makes the iQOO feel far more aggressive in terms of value.

Verdict

The Vivo X300 FE justifies its pricing through camera refinement and premium usability, but the iQOO 15 offers significantly stronger value for users focused on performance and specifications.

Conclusion

The Vivo X300 FE stands out as a compact premium flagship that prioritizes photography, balanced usability, and refined day-to-day comfort. Its Zeiss camera tuning, autofocus selfie camera, wireless charging support, and manageable form factor make it feel more polished for users who value the overall experience rather than pure specifications. The software and camera optimization also give it a more mature flagship personality.

The iQOO 15, on the other hand, feels built for enthusiasts who want maximum hardware for the price. The Snapdragon 8 Elite Gen 5 processor, larger battery, sharper 144Hz display, faster connectivity standards, and aggressive pricing create a package that is extremely difficult to ignore. It feels more ambitious and performance-driven throughout.

Verdict

Vivo X300 FE is the better choice for camera-focused users wanting a refined compact flagship experience. iQOO 15 is the smarter pick for gamers, power users, and buyers seeking flagship-level hardware with stronger overall value.
