iQOO 15 packs 8K VC heat sink and brings a 47% improvement in heat dissipation.

In the cutthroat flagship smartphone race, keeping things cool has become just as important as raw power. That’s exactly where iQOO is aiming to make a mark with its upcoming iQOO 15, a device that’s shaping up to be a true powerhouse for gamers. The company is teasing a new and more effective cooling system designed to help the iQOO 15 get the most out of the Snapdragon 8 Elite Gen 5 during sustained heavy workloads.

According to official posts on Weibo, iQOO’s highlight this year is the 8K (8000 mm²) VC Ice Dome cooling system — reportedly the largest vapor chamber ever used in an iQOO phone. For context, last year’s iQOO 13 boasts a “7K Ultra VC Cooling System”. The company says this new design brings a 47% improvement in heat dissipation compared to its predecessor, thanks to the larger VC heat sink and a double-layer high thermal conductivity graphite sheet.

iQOO product manager @戈蓝V noted that the VC heat sink of the iQOO 15 is more than three times the size of the iPhone 17 Pro Max’s.

But iQOO isn’t stopping at cooling. Every variant of the iQOO 15 will come with a factory-applied anti-reflective protective film, something the company claims is unique in the industry. It’s a premium addition aimed at improving screen visibility under bright light.

The display itself also sounds impressive. The iQOO 15 uses a 2K Samsung Everest panel built on M14 luminous material, the latest generation from Samsung that offers a 40% boost in luminous efficiency. Peak brightness figures are equally eye-catching: 1000 nits (manual), 2600 nits (full-screen), and a blinding 6000 nits (local peak) — great for HDR content or gaming outdoors.

Other features include IP-rated waterproofing, ultrasonic fingerprint recognition, dual symmetrical speakers, and a 091640 X-axis vibration motor for more precise haptic feedback.

The iQOO 15 is set to debut on October 20 at 19:00 in China with the brand’s new Q3 gaming chip, and if the numbers hold true, it could become one of the most technically advanced gaming phones this year.
