It competes with the Realme GT 8 Pro, Redmi K80 Pro, and OnePlus 13R, offering unique hardware-level gaming optimizations that set it apart.

Design and Build Quality

The iQOO 15 adopts a gamer-oriented design that’s more restrained than previous generations. The BMW M Motorsport branding returns on some variants, and the triple-camera module is neatly integrated. RGB lighting elements are present on the back, customizable through settings. The metal frame provides rigidity, though the IP64 rating only covers dust and light splashes.

The 144Hz LTPO display is a Samsung E7 panel with a remarkable 3000 nits peak brightness. Touch sampling rate reaches 1200Hz in gaming mode, making input feel instant. The ultrasonic dual-position fingerprint sensor is wide enough to register with either thumb comfortably.

Performance

The combination of the Snapdragon 8 Elite Gen 3 and the Q3 gaming chip produces exceptional results. The Q3 handles frame interpolation, allowing the phone to render games at native 72fps and output at 144fps — doubling smoothness without doubling workload. In Genshin Impact, the iQOO 15 maintains 59.5 fps average at max settings over 30 minutes with peak temperatures at just 39°C, thanks to the massive vapor chamber and graphite cooling. In Honor of Kings, it runs at a locked 120fps.

The 120W flash charging (using dual-cell architecture) refills the 5500mAh battery in roughly 25 minutes — perfect for topping up between gaming sessions.

Camera

The triple 50MP camera system is surprisingly capable for a gaming-focused phone. The IMX921 main sensor captures detailed photos with reliable HDR. The 50MP ultra-wide matches the main sensor in resolution, maintaining color consistency. The 2x telephoto doubles as a portrait lens with natural bokeh. While it doesn’t match the Vivo X200 Pro’s camera quality, it’s significantly better than most gaming phones.
