The Flagship Killer era is over; the Super Smartphone era has begun. For years, iQOO has been synonymous with raw gaming performance, but with the iQOO 15, the brand is aiming for something higher: total dominance. By combining a massive 7,000 mAh battery with the industry’s most powerful mobile processor. We put the iQOO 15 through its paces with heavy testing, battery drain loops, and competitive gaming to see if it truly earns the title of the Super Smartphone of 2025.
- Performance: A Pocket Supercomputer
Powered by the Snapdragon 8 Elite Gen 5 processor and the dedicated SuperComputing Chip Q3, the iQOO 15 feels less like a phone and more like a pocket-sized supercomputer. Running on OriginOS 6, the device is aggressively fast.
Gaming: It delivers a genuinely lag-free experience. We consistently hit stable 120 FPS and 144 FPS in games like BGMI and COD Mobile.
Thermals: Thanks to the massive 8K VC Cooling System, the phone stays impressively cool under load. Even during extended gaming sessions, the temperature remained moderate (38-39°C) a huge engineering win.
Haptics: The Dual-Axis Vibration Motor is a standout feature. It delivers precise, multidirectional feedback that makes gaming recoil and system interactions feel incredible.
Benchmark Validation: In our testing, the iQOO 15 recorded a massive AnTuTu score of 3,758,397, edging past the Realme GT 8 Pro (3,748,836) and significantly outperforming the OnePlus 15 (3,474,182). This confirms its status as the current performance king.
- Display: Brightest in Class
The visual experience is driven by a 6.85-inch Samsung 2K M14 LEAD™ first time in android and OLED LTPO panel with a 144 Hz refresh rate.
Techarc Validation: We verified the High Brightness Mode (HBM) at 2,600 nits, making it the brightest panel we have tested (beating the Google Pixel 10 Pro’s 2,250 nits).
Visibility: With a peak brightness of 6,000 nits and the industry’s first Triple Light Sensor system, auto-brightness is faster and smarter. Text remains razor-sharp (508 PPI) and legible even under harsh direct sunlight.
- Battery & Charging: The Endurance Champion
The standout feature is the brand-new 7,000 mAh Silicon-Anode battery. Despite this massive capacity, the phone feels surprisingly light.
Charging: The 100W FlashCharge tops up the device from 0–100% in approximately 53 minutes.
Real-World Use: In our heavy usage test (gaming, 5G data, and 4K recording), it managed over 10 hours of Screen-on-Time (SoT), making it arguably the best endurance flagship in its segment.
- Camera: Cinematic & Versatile
The iQOO 15 features a 50 MP triple rear camera setup (Main + Ultrawide + 3x Telephoto) and a 32 MP front camera.

Video: It records up to 8K 30fps and 4K 60fps with excellent stabilization. The footage is detailed with a cinematic look.
Photography: The wide range of professional controls allows enthusiasts to extract high-quality shots without needing heavy gear. The output is consistently impressive, shedding the old reputation that gaming phones have bad cameras.
- Software & UI
The iQOO 15 marks a significant milestone as the first smartphone in India to launch with OriginOS 6 out of the box. The software experience is exceptionally smooth, featuring a complete overhaul of the UI, animations, and app layout design that feels modern and fluid.
Beyond the immediate performance, iQOO has committed to an impressive long-term support policy. Users are guaranteed 5 major Android OS updates, meaning the device which ships with Android 16 will be supported all the way through Android 21 (expected in 2030). Furthermore, the device will receive 7 years of security patches, ensuring protection against bugs and vulnerabilities until roughly late 2032. This level of support makes the iQOO 15 a solid long-term investment.
- AI & Connectivity
The device is future-proofed with Wi-Fi 7, all major 5G bands, NFC, and an IR blaster. The Ultrasonic Fingerprint Sensor is lightning fast, and AI features like live call translation and image enhancement are genuinely useful, not just gimmicks.
- Critical Feedback
The Two App Store Problem: We strongly urge iQOO to reconsider having two separate app stores (V-Appstore and Google Play Store) pre-installed. This redundancy creates a cluttered experience that goes against the minimalist philosophy premium users prefer. A cleaner UI would make this device truly perfect.
- Conclusion: The Verdict
The iQOO 15 is a triumph of engineering. It successfully bridges the gap between a hardcore gaming rig and a premium daily driver. With the highest AnTuTu score we’ve tested, a 7,000 mAh battery that refuses to die, and a display that outshines the competition, it is the default choice for power users in 2025.
