Comparing the OPPO Find X9 Ultra vs Vivo X300 Ultra vs Xiaomi 17 Ultra smartphones to see how their camera tech, battery life, gaming smarts and other bits stack up. Which is the best phone for you? Sure, the OPPO Find X9 Ultra sports some insane telephoto camera action, but its rivals aren’t far behind. The Vivo X300 Ultra also boasts one of the best camera phone setups of 2026, while the Xiaomi 17 Ultra is just as beefy with solid specs.
If you’re after some of the best hardware that you can stuff into your shorts, you certainly came to the right video. I’ve reviewed all three of these phones and you can also see my videos on ColorOS, HyperOS and OriginOS right here on Tech Spurt.
The OPPO Find X9 Ultra, Vivo X300 Ultra and Xiaomi 17 Ultra have a lot in common. They’re all powered by the same powerful Snapdragon chipset, so the gaming experience is second to none. All three also offer up a large 6000mAh-plus battery, although I did find that one of this smartphone trio wasn’t as dependable as the others for all-day life.
The OPPO Find X9 Ultra serves up better camera hardware on paper, and I already gushed all over it in my review. However, the Vivo X300 Ultra uses the same main sensor and is certainly one of the best phones in 2026 for snapping photos and video.
