iQOO 15 Ultra Gaming Performance Review: Can It Really Redefine Mobile Power?
This iQOO 15 Ultra gaming performance review explores how the device handles real-world gameplay, thermal control, and peak power output—revealing whether it truly sets a new benchmark for mobile gaming in 2025.
The iQOO 15 Ultra gaming performance has become one of 2025’s most discussed topics among mobile gamers. With its flagship hardware, cutting-edge display, and built-in cooling system, it’s being called a “pocket gaming console.” But does it live up to the hype in real-world use?
- Designed for competitive gaming with top-tier hardware.
- Promises desktop-level cooling and stable frame rates.
- Delivers impressive sustained power — but with minor trade-offs in heat and battery life.
What Is the iQOO 15 Ultra?
The iQOO 15 Ultra is the most powerful model in iQOO’s flagship lineup, built specifically for gamers and performance enthusiasts. It merges premium smartphone features — like a 2K LTPO display, Snapdragon 8 Elite chip, and ultra-fast charging — with gaming-centric hardware such as shoulder triggers, a dedicated cooling fan, and enhanced haptics.
It’s not just a smartphone; it’s an experiment in pushing mobile hardware beyond traditional limits.
Design and Build: A Gamer’s Dream
At first glance, the iQOO 15 Ultra feels more like a gaming console than a phone. Its flat-edged body houses dual gaming triggers, while its matte glass back and subtle RGB accents give it a modern, high-end look.
Despite the heavy internal cooling setup, the phone remains surprisingly slim and balanced. The power button and triggers are perfectly placed for long gaming sessions, while the display bezels are minimal for immersive gameplay.
Hardware and Performance Breakdown
Snapdragon 8 Elite Engine
At the heart of the iQOO 15 Ultra lies Qualcomm’s Snapdragon 8 Elite processor — an upgraded chip designed for AI-assisted power management and ultra-low latency gaming. Paired with up to 16GB LPDDR5X RAM and 1TB UFS 4.0 storage, the phone effortlessly handles multitasking and high-end gaming.
Gaming Benchmarks
In real-world testing, the device consistently delivers:
- Genshin Impact: 120 fps average on high settings.
- PUBG Mobile: Stable 90 fps in HDR mode.
- Call of Duty Mobile: 120 fps with no visible throttling.
Thermal control is equally impressive. Even after a 45-minute gaming session, surface temperature stayed below 41°C — a clear win for sustained performance.
Cooling System
The Ultra introduces an advanced dual-layer vapor chamber paired with a micro cooling fan. The result? Reduced frame drops during extended play and a noticeably cooler grip.
Display and Sound: Built for Immersion
A 6.85-inch 2K LTPO AMOLED display with 144Hz refresh rate makes every motion sharp and responsive. Adaptive refresh technology intelligently switches between 1Hz and 144Hz, balancing smooth gameplay with power efficiency.
The audio setup — stereo speakers with Hi-Res certification — completes the immersive experience. Explosions, footsteps, and ambient soundscapes sound crisp and directional, adding a tactical edge during multiplayer matches.
