The iQOO 15 Ultra has officially stepped into the spotlight, and it is clear that this device is not trying to play it safe. As the first Ultra-branded smartphone from iQOO, it aims to combine raw performance, advanced cooling, long battery life, and capable cameras in one solid package. While many brands focus on just one highlight feature, this phone attempts to cover every angle, especially for power users and mobile gamers.
At the heart of the device sits the Snapdragon 8 Elite Gen 5 processor built on a 3nm architecture. This chip is designed for top-tier speed and efficiency, ensuring smooth gaming, multitasking, and long-term reliability. But power alone is not enough in 2026. Managing heat is just as important, and that is where this device truly stands apart.
Ice Dome Active Cooling Changes the Game
Most flagship smartphones rely on vapor chamber cooling systems. The iQOO 15 Ultra takes things further with its Ice Dome active cooling technology. Inside the phone is a 17x17mm physical fan that actively pushes hot air out through a side vent. This approach is uncommon in mainstream flagship phones and more often seen in niche gaming devices.
What makes this engineering impressive is that the phone still carries IP68 and IP69 water and dust resistance ratings. Integrating a fan without sacrificing durability shows serious attention to design. During heavy gaming sessions, even while charging, the device reportedly maintains stable temperatures around 42 degrees Celsius. This level of thermal control means sustained high frame rates without uncomfortable heat buildup. For competitive gamers, that consistency matters.
Massive 7400mAh Battery Redefines Endurance
Battery life is another area where the iQOO 15 Ultra breaks away from the crowd. Packed inside its 8.7mm body is a 7400mAh silicon-anode battery. While most flagship phones remain around 5000mAh, this device pushes capacity much further without becoming excessively thick.
For gamers and travelers, this means fewer charging breaks and more uninterrupted usage. Heavy users can comfortably stretch usage beyond a full day, while moderate users may find themselves charging every other day. Despite the large battery, charging speeds remain fast. The phone supports 100W wired charging and 40W wireless charging, allowing quick top-ups whenever needed.
2K 144Hz Display Built for Speed and Clarity
The front of the iQOO 15 Ultra is dominated by a 6.85-inch 2K+ curved Samsung M14 LTPO AMOLED display. With a 144Hz refresh rate, scrolling and gaming feel incredibly fluid. The adaptive LTPO technology adjusts the refresh rate dynamically, helping balance performance and battery efficiency.
One of the standout features is the peak brightness rating of up to 8000 nits. This ensures strong outdoor visibility, even under direct sunlight. Whether watching HDR content, browsing social media, or playing competitive titles, the display delivers sharp visuals and smooth motion that match the phone’s performance ambitions.
Triple 50MP Cameras Add Versatility
Gaming phones often compromise on camera quality, but the iQOO 15 Ultra aims for balance. It features a triple 50MP rear camera setup that includes a primary Sony IMX921 sensor, a 3x periscope telephoto lens, and an ultra-wide lens.
The main sensor captures detailed shots with good clarity, while the periscope camera allows optical zoom without significant loss of detail. The ultra-wide lens supports landscape photography and group shots. On the front, a 32MP selfie camera handles video calls and social media content reliably. This setup ensures that the phone appeals not only to gamers but also to users who expect strong everyday photography performance.
Premium Hardware and Future-Ready Connectivity
The iQOO 15 Ultra is available with up to 24GB LPDDR5X RAM and 1TB of UFS 4.1 storage, offering ample space and speed for demanding applications. It runs Android 16 with OriginOS 6.0, providing a modern software experience.
Connectivity options include 5G SA/NSA support, Wi-Fi 7, Bluetooth 6.0, NFC, and a USB Type-C 3.2 Gen1 port. Stereo speakers and Hi-Fi audio enhance media consumption, while the in-display 3D ultrasonic fingerprint scanner ensures fast and secure unlocking.
Pricing and Market Position
The device starts at 5,699 yuan for the 16GB + 256GB variant and goes up to 7,699 yuan for the 24GB + 1TB model. Considering the advanced cooling system, massive battery, high-end display, and flagship chipset, the pricing positions it competitively within the premium segment.
Final Verdict
The iQOO 15 Ultra is more than just a gaming smartphone. It combines powerful hardware, intelligent thermal management, long-lasting battery life, and capable cameras into a single polished device. By integrating active cooling without sacrificing durability and pairing it with a massive battery, iQOO has created a flagship that feels engineered for real-world performance. For users who demand sustained speed, endurance, and versatility, this phone sets a strong benchmark for 2026.
