New Delhi [India], March 13 (ANI): After I moved past the initial unboxing phase and started living with the iQOO 15 as a primary device, my focus shifted to daily reliability. The brand calls it a flagship killer, my long-term usage reveals a device that comes with great ergonomics and display, but there are rooms of improvement when it comes to optics and endurance. So, let me tell you all about my long-term usage of the iQOO 15 and help you make the right decision on whether to choose this as your next reliable long-term device.
Design and Ergonomics- The Handfeel Factor:
One of the most immediate positives over the long term is the build quality. Weighing roughly 220g, the hand-feel is well-balanced. The shift toward flat sides offers a secure grip that makes the phone feel more manageable, much like its predecessor. The matte finish on the back glass is a practical choice for long-term use, as it remains pristine and free of fingerprints even without a case. While the white aesthetic is clean, it leans toward the minimal side, which may feel plain to those looking for a more aggressive gaming look.
The Monster Halo Light (or Dynamic Light) is another signature iQOO touch that surrounds the camera module, but after a month of usage, its novelty tends to wear off. While the customizable RGB glows are visually striking during unboxing and can be synced with notifications or gameplay, the effect is often too subtle to be truly functional, frequently going unnoticed when the phone is placed screen-up or tucked into a pocket.
Display- The Trump Card:
In my opinion, the screen is arguably the strongest argument for the iQOO 15's longevity. Utilizing Samsung's M14 2K LTPO AMOLED panel, the display remains a standout. Whether indoors or under harsh sunlight, the 2,600 nits peak brightness and 144Hz refresh rate ensure a top-tier visual experience. For long-term content consumption, the higher resolution and superior contrast levels give it a slight edge over the 1.5K panels found on many of its contemporaries.
Camera- Improved Hardware, Controversial Processing:
The transition to a triple 50MP setup, featuring a 3x Sony IMX882 periscope lens, suggests a massive leap on paper. However, the real-world output tells a different story compared to the iQOO 13.
* Aggressive Sharpening: The software processing tends to over-sharpen images, sometimes leading to a "fake" look in high-contrast scenarios.
* Video Limitations: While it handles 4K/60fps well, it is artificially limited in portrait video (1080p), and the absence of 4K/120fps is a missed opportunity given the power of the Snapdragon 8 Elite.
* Consistency: While the periscope lens is great for portraits, the overall color science occasionally lacks the natural warmth and consistency found in the previous generation or its main rivals.
Performance and Sustainability:
Powered by the Snapdragon 8 Elite and the dedicated Q3 chip, the performance ceiling is incredibly high. Long-term gaming sessions remain stable thanks to the massive 8K vapor chamber, which prevents the device from becoming uncomfortably hot. One major win for long-term owners is the updated software policy: 5 years of Android updates and 7 years of security patches. This puts the iQOO 15 ahead of the standard flagship cycle, making it a viable long-term investment.
Gaming Experience- The Esports DNA:
iQOO's reputation for gaming remains its strongest pillar, and the iQOO 15 doubles down on this with a dedicated hardware stack. The self-developed Supercomputing Chip Q3 acts as a mobile graphics card, enabling PC-grade 144 FPS frame interpolation and hardware-level Ray Tracing, which brings console-like lighting and reflections to titles like Genshin Impact. During extended sessions, the 8K vapor chamber cooling system, the largest in the brand's history, effectively keeps thermals under control, maintaining a stable 120 FPS without aggressive throttling.
Furthering the immersion is the symmetrical dual-axis vibration motor, providing direction-aware 4D haptics that allow you to feel which direction enemy fire is coming from. For those who play while charging, Bypass Charging 2.0 is a lifesaver, as it powers the phone directly and bypasses the battery to prevent heat buildup, ensuring the device stays cool and battery health is preserved over the long term.
Battery- The Competitive Gap:
The iQOO 15 packs a massive 7,000mAh battery, which sounds invincible. However, when placed side-by-side with the OnePlus 15 (7,300mAh) or the Oppo Find X9 Pro, the efficiency isn't quite at the same level. Even without comparing it to other phones, the device doesn't quite live up to the 7,000mAh tag, as it barely manages a day of heavy usage.
* Charging Speeds: The move from 120W in previous models to 100W wired and 40W wireless is a functional shift. While 100W is still incredibly fast (full charge in under an hour), it lacks the "rapid" edge seen in the OnePlus 15's 120W/50W combo.
* Endurance: Expect a solid 1.5 days of medium-level use, but heavy users might find the OnePlus or Oppo alternatives stretching further into the second day without breaking a sweat.
In The End:
Priced at Rs 72,999 (12GB+256GB) and Rs 79,999 (16GB+512GB), the iQOO 15 is a refined powerhouse that somewhat nails the essentials of a high-end experience, especially the hand-feel and the display. However, the camera processing needs software tuning to match the soul of the iQOO 13, and the battery, while large, doesn't quite take the crown from its closest rivals. Despite having the Snapdragon Gen 5 Elite, I wanted more out of this phone. But for those prioritising raw power and a future-proof update cycle, it remains a top contender.
My Rating: 3.5/5
