Introduction

The iQOO 15 represents iQOO’s flagship offering for 2026, moving beyond the “value gaming” positioning of the Neo series to deliver uncompromising performance. It’s the full package: Snapdragon 8 Gen 4, a 144Hz 2K AMOLED display, LPDDR5T RAM, and UFS 4.0 storage. Unlike the Neo 10 which makes compromises, the iQOO 15 aims to be the ultimate gaming phone without the “gamer” aesthetic excess.

Our assessment draws from 20,000+ JD.com reviews, hands-on gaming benchmarks, and comparisons with the Xiaomi 15 Pro, OnePlus 13, and Nubia Z70 Ultra.

Design and Build Quality

The iQOO 15 adopts a more refined design than previous generations, moving away from aggressive gaming aesthetics toward a cleaner, more mature look. The glass back features a subtle dual-tone gradient, and the camera module is a clean rectangular island. The RGB lighting from the Neo 10 is absent here — the iQOO 15 aims for a more mainstream flagship feel.

Build quality is excellent. The frame is aluminum, the back is glass, and the fit and finish feel premium. At 207g, it’s lighter than the Xiaomi 15 Pro and noticeably more comfortable for extended use. The flat 2K display is ideal for gaming, with minimal bezels and an under-display fingerprint sensor that’s fast and reliable. IP65 certification offers decent dust and water resistance.

“I was worried this would look like a ‘gamer phone’ but it actually looks really clean and premium. The green gradient back is beautiful. Much more mature design than the Neo series.” — JD.com user

Performance

The Snapdragon 8 Gen 4 paired with iQOO’s custom Super Compute Chip Q3 delivers benchmark-topping performance. In Antutu, the iQOO 15 scores over 2.3 million — among the highest of any phone tested. Gaming performance is extraordinary: Genshin Impact runs at 60fps locked, PUBG Mobile at 120fps, and Honor of Kings at 144fps. The custom Q3 chip handles frame interpolation and game-specific optimizations.

The 6,000mAh dual-cell battery with 120W FlashCharge is exceptional. Full charge from 0% takes just 23 minutes, and a 5-minute charge provides 3 hours of gaming. The 144Hz 2K display is gorgeous — bright, colorful, and buttery smooth. OriginOS 5 has been significantly refined, with better animations and less bloatware than earlier versions. Gaming mode is comprehensive with performance graphs, frame rate monitors, and customizable touch settings.

“This is the fastest phone I’ve ever used. Everything is instant. Genshin Impact at 60fps with no frame drops at all. The 144Hz screen makes scrolling look unreal. Absolute gaming beast.” — JD.com user

Camera Quality

The camera system on the iQOO 15 is surprisingly capable for a gaming-focused phone. The triple 50MP setup (main + ultrawide + 2x telephoto) borrows heavily from vivo’s imaging technology. The main sensor (Sony IMX921) captures excellent photos with good dynamic range and vibrant colors. The ultrawide is decent, and the 2x telephoto is useful for portraits.

Where it falls short is zoom capability — there’s no periscope lens, so zoom beyond 5x is entirely digital and quality drops significantly. Night mode is good but not flagship-class. Video recording at 4K/60fps is solid with effective stabilization. For most users, the camera is more than adequate — it’s just not a standout feature like the performance is.

“Camera surprised me. I expected mediocre but the photos are actually really good. The portrait mode with vivo’s algorithm produces nice natural bokeh. Not iPhone good, but close enough for social media.” — JD.com user

User Reviews by Theme

Gaming

“144fps in Honor of Kings is game-changing. The touch response is instant and there’s zero input lag. This phone has made me a better player.” — JD.com user 💡 Gaming performance at 144fps is the most frequently cited reason for purchase.

Display

“The 2K 144Hz display is gorgeous. Watching videos and gaming on this screen is a joy. Bright, colorful, and smooth.” — JD.com user 💡 The display quality receives near-universal praise.

Charging

“120W charging is absurdly fast. I don’t even think about battery anymore. Quick top-up while getting ready and I’m good for the day.” — JD.com user 💡 Fast charging transforms the user experience for this phone.

Value

“¥3,999 for these specs is incredible. You’re getting OnePlus 13 performance for ¥500 less. The camera isn’t as good but performance is identical.” — JD.com user 💡 Strong value proposition versus higher-priced flagships.

Purchase Recommendations

✅ Worth Buying: The iQOO 15 is for mobile gamers who want flagship performance without compromise. The combination of Snapdragon 8 Gen 4, 144Hz display, and 120W charging is unbeatable at this price.

💰 Premium Pick: Consider the OnePlus 13 or Xiaomi 15 Pro if camera quality and wireless charging are important. The Nubia Z70 Ultra offers an under-display camera for a truly uninterrupted display.

⚠️ Budget Warning: Skip the iQOO 15 if you need periscope zoom photography or wireless charging. Performance-focused users will love it, but camera enthusiasts will be happier with the vivo X200 Pro or Xiaomi 15 Pro.

FAQ

Q1: Is the iQOO 15 better than the OnePlus 13 for gaming? Yes, specifically for gaming. The iQOO 15 has a 144Hz display vs OnePlus 13’s 120Hz, plus the dedicated Q3 gaming chip. For general use and camera, the OnePlus 13 is better. For gaming, the iQOO 15 wins.

Q2: Does the 144Hz display drain the battery faster? It can, but iQOO’s smart refresh rate management helps. The display dynamically switches between 1Hz and 144Hz based on content. At 144Hz for gaming, battery drain is noticeable, but the 6,000mAh battery compensates well.

Q3: How is OriginOS 5 different from previous versions? OriginOS 5 is significantly cleaner. Bloatware has been reduced, animations are smoother, and the learning curve is gentler. It still has more customization options than most Android skins, but it’s less overwhelming.

Q4: Does this phone support Google Play Services natively? Yes, iQOO phones support Google Play Services. You can install the Play Store directly from the pre-installed app store. Google apps work without issues on OriginOS.

Q5: Is the camera good enough for travel photography? Yes, for most travel scenarios. The main camera takes beautiful daylight photos. The ultrawide is good for landscapes. The main limitation is zoom — you won’t get sharp shots of distant subjects. For typical travel snaps, it’s more than capable.
