Benchmark Scores and Real-World Tests Impress British Reviewers
The iQOO 15 is turning heads across the UK tech community as performance benchmarks and early test results reveal just how powerful the new flagship truly is. British reviewers and enthusiasts are calling it one of the most impressive Android phones of 2025, praising its speed, efficiency, and thermal stability. With iQOO’s focus on gaming and performance optimization, the device appears to have delivered a level of raw power that rivals — and in some cases surpasses — industry leaders like Samsung, Google, and OnePlus.
According to early reports from UK-based tech testers, the iQOO 15’s performance metrics are nothing short of groundbreaking. Powered by Qualcomm’s Snapdragon 8 Gen 4 chipset paired with up to 16GB of LPDDR5X RAM and UFS 4.0 storage, the phone achieves benchmark scores that exceed 2.4 million on AnTuTu — placing it at the top of current Android rankings. Geekbench results also reflect major CPU and GPU improvements, highlighting the chip’s efficiency and the phone’s impressive sustained performance during heavy workloads.
British reviewers emphasize that these scores aren’t just numbers; they translate directly into real-world performance gains. The iQOO 15 handles demanding tasks such as high-end gaming, 4K video editing, and multitasking with ease. Games like Call of Duty: Mobile and Genshin Impact run at maximum settings without frame drops, even during long sessions. Reviewers attribute this consistency to iQOO’s advanced vapor chamber cooling system, which helps maintain stable temperatures and smooth performance over time — a key advantage over many competing flagships.
Tech bloggers in the UK also note that the iQOO 15’s Funtouch OS, based on Android 15, feels optimized and refined. The interface runs fluidly, with near-instant app launches and minimal background lag. Many users who previously preferred OnePlus or Pixel phones are impressed by how clean and stable iQOO’s software feels, signaling a shift in perceptions about the brand’s user experience. Some reviewers even called it the most polished version of Funtouch OS yet, pointing to improved responsiveness and deeper system customization options.
One of the most discussed aspects in the UK tech scene is the iQOO 15’s gaming performance. With its high-refresh 144Hz AMOLED display, adaptive frame-rate control, and powerful GPU optimization, the device offers one of the most immersive gaming experiences available today. Reviewers found that long play sessions remained smooth with minimal heat buildup, even when plugged in and charging. The phone’s dedicated “Performance Mode” dynamically adjusts system resources, giving competitive gamers precise control over responsiveness and thermal output — features usually reserved for gaming phones.
Beyond gaming, productivity and battery performance also impressed the British audience. The 7,000mAh battery provides exceptional endurance, easily lasting through a full day of intense use. Combined with 120W fast charging, users can get back to full power in under 30 minutes. Reviewers highlighted that this combination of endurance and speed gives the iQOO 15 a major advantage in everyday usability. For professionals, creators, and gamers alike, the device delivers sustained energy and performance without compromise.
Design and ergonomics have also received praise from UK reviewers. The iQOO 15’s sleek aluminum body, subtle matte finish, and premium build quality rival more expensive competitors. The curved edges and balanced weight distribution make it comfortable to hold during extended use. The attention to detail, from the haptic feedback to the stereo speakers, reinforces the phone’s flagship-level craftsmanship — something that further validates its growing reputation as a true competitor in the premium smartphone space.
In summary, the iQOO 15’s performance results have stunned the UK tech audience by proving that a relatively new brand can challenge — and even outperform — established global leaders. Its combination of the Snapdragon 8 Gen 4, superior thermal management, exceptional battery life, and software optimization makes it one of the most complete smartphones of 2025. As anticipation grows for a confirmed UK launch date, many British tech experts believe that iQOO has delivered not just another high-performance phone, but a device capable of redefining user expectations in the flagship Android segment.
