Vivo X300 vs iQOO 15

The Vivo X300 vs iQOO 15 battle lands right in the ₹70,000–₹75,000 segment. Both phones target different users, yet they compete fiercely for the same spotlight. Prices sit close together. The X300 starts around ₹75,999, while the iQOO 15 sits near ₹72,999.

The story is simple but fiery: one phone pushes raw speed, while the other elevates mobile photography. Let’s break it down.

Design: Compact Precision vs Bold Performance Build

The Vivo X300 stands out first. Its compact 6.31-inch size feels refreshing today. The slim 7.99mm frame and 190g weight make it a joy to hold. Moreover, the Coral Velvet Glass texture and the unibody curves add a premium feel without flashiness. It looks clean, balanced, and intentionally minimal.

The iQOO 15 goes the other direction. Its 6.85-inch size and 220g body feel massive. However, the weight distribution is excellent, and the tri-color aesthetic on the Legend variant adds flair. The polished metal frame, tighter edges, and Monster Halo lighting make it bold and sporty.

Both offer IP68 and IP69, yet the X300 feels more pocket-friendly and easier for one-hand use.

Advantage: Vivo X300 for compact elegance.

Display: Bright and Smooth vs Powerful and Immersive

The X300’s 6.31-inch LTPO display gets bright at 4500 nits in local areas. Even the 2000-nit global peak stays visible outdoors. Motion remains smooth with UltraMotion, lifting refresh rates for many apps. The panel looks natural, controlled, and easy on the eyes.

The iQOO 15’s 6.85-inch 2K 144Hz AMOLED is built for fans of big screens. It pushes up to 6000 nits and uses anti-reflective film for clarity. The no-polarization tech improves angles, and Wet Touch works better than many rivals.

Both look stunning, yet their strengths differ. The iQOO 15 is more immersive, while the Vivo X300 stays sharp and comfortable.

Advantage: iQOO 15 for sheer size and brightness.

Performance: Pure Muscle vs Efficient Power

The iQOO 15 leans into performance with the Snapdragon 8 Elite Gen 5. It achieves higher benchmark numbers. Paired with the Q3 gaming chip, it hits elite gaming levels with ray tracing, 144FPS support, and low-heat output. The large vapor chamber enhances stability during intense sessions.

Meanwhile, the Vivo X300 uses the Dimensity 9500 chip. It feels smooth, responsive, and efficient. It scores lower on benchmarks, yet real-world performance remains stable. The Glacier Cooling system avoids overheating, and the device stays cool even during long gaming periods.

Gamers will feel the difference. The iQOO stays ahead with its raw power and gaming-first tuning.

Advantage: iQOO 15 for performance and gaming.

Camera: The Clear Divide

This is where the fight becomes one-sided.

The Vivo X300 arrives with a 200MP ZEISS main camera, V3+ chip, and ZEISS Portrait tuning. Images look sharp, clean, and natural. Low-light performance is outstanding with controlled noise and balanced colors. Portraits look lifelike with subtle depth and texture.

The telephoto system with 100x HyperZoom keeps detail intact even at long range. The 50MP autofocus front camera produces crisp selfies.

The iQOO 15 offers a solid 50MP triple setup and a 3x periscope lens. Photos look natural and accurate. However, the X300 delivers superior detail, dynamic range, night imaging, and zoom clarity.

Photography lovers will notice the difference immediately.

Clear Advantage: Vivo X300 — easily.

Battery & Charging: Big Cell vs Smart Optimization

The iQOO 15 packs a huge 7000mAh battery with 100W charging. It lasts longer and charges faster. It also recovers apps quickly after shutdown.

The Vivo X300 features a 6040mAh battery with 90W charging and 40W wireless charging. It lasts a full day comfortably thanks to better optimization and a lighter system design.

Heavy users may prefer iQOO, while balanced users will find the X300 reliable.

Advantage: iQOO 15 for endurance.

Verdict: Compact Powerhouse vs Performance Monster

• Choose iQOO 15 if you want raw power, long battery life, and elite gaming tools.
