What Are The Specs Of iQOO 15 Vs Vivo X300 Pro?

Let’s start with the basics. Both iQOO 15 vs Vivo X300 Pro pack incredible hardware, but the differences can be significant depending on how you use your phone. Here is a quick glance:

iQOO 15 Vs Vivo X300 Pro: Design & Display

When you pick up the iQOO 15, you immediately notice its massive 6.85-inch 2K LTPO AMOLED display with a buttery-smooth 144Hz refresh rate. That means scrolling, gaming, and streaming feel incredibly fluid. Colors pop, blacks are deep, and HDR content looks stunning.

The Vivo X300 Pro isn’t far behind. Its 6.78-inch AMOLED panel hits 2800 × 1260 pixels, giving you a crisp viewing experience. The 120Hz refresh rate is slightly lower than the iQOO 15, but still impressively smooth. Plus, the Vivo screen packs a high 452 PPI, which ensures everything looks sharp down to the tiniest detail.

If you’re someone who spends a lot of time watching videos or playing high-end games, the iQOO 15 slightly edges out in fluidity. But Vivo’s display is no less either; it’s just a matter of how sensitive your eyes are to ultra-high refresh rates.

iQOO 15 Vs Vivo X300 Pro: Performance

Now, let’s talk about the performance of both iQOO 15 Vs Vivo X300 Pro. The iQOO 15 comes with the Snapdragon 8 Elite Gen 5 processor, an octa-core chipset running up to 4.6 GHz. Whether you are gaming, editing videos, or juggling multiple apps, this phone handles it all effortlessly. With 12GB RAM, multitasking feels smooth and lag-free.

The Vivo X300 Pro sports the Dimensity 9500, another flagship-grade chip. It’s incredibly capable and optimized for energy efficiency. However, raw power benchmarks slightly favor the iQOO 15, especially in sustained heavy gaming sessions.

In short, if you want the fastest performance with extreme reliability, the iQOO 15 might have a subtle edge. But Vivo X300 Pro is still more than enough for nearly any demanding task.

iQOO 15 Vs Vivo X300 Pro: Camera

Both iQOO 15 Vs Vivo X300 Pro aim to impress photography enthusiasts. The iQOO 15 offers a triple 50MP rear camera setup- wide, telephoto with 3x optical zoom, and ultrawide- plus a solid 32MP front camera. You can expect detailed shots, accurate colors, and versatility across different photography modes.

Meanwhile, the Vivo X300 Pro goes big with 50MP + 50MP + 200MP rear cameras and a 50MP front camera. The 200MP sensor is particularly impressive for zoomed-in shots and high-resolution photography. It’s designed to capture incredible detail in almost any lighting condition.

If photography is your top priority, Vivo X300 Pro takes the lead thanks to its higher megapixel sensors and advanced imaging features. But the iQOO 15 still delivers strong performance, especially if you prefer more natural color tones and video stabilization.

• iQOO 15: With the Snapdragon 8 Elite Gen 5 and 144Hz display, it’s perfect for high-frame-rate gaming. Graphics are smooth, and the large battery ensures long play sessions without interruptions.
• Vivo X300 Pro: The Dimensity 9500 is a strong performer too, but the slightly lower refresh rate (120Hz) may make a difference in ultra-competitive, fast-paced games. However, Vivo’s cooling and optimization still deliver a fantastic gaming experience.

If gaming is your priority, the iQOO 15 could be more satisfying for long sessions, especially with high-refresh-rate games.
