The Asus Zenfone 10 offers a better overall performance, longer battery life, and a higher quality camera compared to the OnePlus 9. However, it is more expensive. The OnePlus 9, while more budget-friendly, has a larger screen, but the camera quality and battery life are not as good as the Zenfone 10. If camera performance and battery life are very important to you and you are willing to pay the upper midrange price, go for the Zenfone 10. If you prefer to save money and want a larger screen, the OnePlus 9 is a solid choice. Both phones run on Android, have an OLED display, and support 5G, so the primary differences to consider are price, camera, battery, and screen size. Give Feedback

"It's the best small phone for fans of compact handsets, but the Asus Zenfone 10 could pull users away from Samsung and Google flagships with top-quality performance and battery life. If you can forgive its more limited photography options and the shorter-than-average software support window, the Zenfone 10 is a top choice."

"If you’re hunting for the best Android camera phone at this price, and one that doesn’t skimp on specs the OnePlus 9 is worth considering. Courtesy of a partnership with Hasselblad, the cameras offer better color correction, and both regular and ultra-wide photos look great. The OnePlus 9’s battery fully charges in under 30 minutes over a cable, and in 45 minutes using wireless charging. If you hate waiting for hours to charge your phone, you'll love the OnePlus 9."

About ASUS
Asus is a well-known player in the mobile world, and in the past few years it has been known for covering specific niches in the smartphone market. Their Zenfone line of devices appeal to small phone enthusiasts, by providing very well-rounded and capable phones at a package that is not too large to operate with one hand – something hard to find in modern Android smartphones. Conversely, their ROG line of devices cater to mobile gamers, by providing a slew of hardware and software features, specifically tailored to enhance the mobile gaming experience. Additionally, Asus is one of the only manufacturers left that continues to include headphone jacks in their lineup of phones, a feature that has become exceedingly rare in today's market.
About OnePlus
OnePlus, established in 2013, is a smartphone brand that first became known for providing flagship-like devices, at a fraction of the cost compared to more expensive Android competitors. OnePlus focuses on creating smartphones with powerful hardware at reasonable prices. They also bring hardware features normally not seen in other Android phones sold in the US, such as their ultra-fast “Warp Charge” and the beloved “Alert Slider”.
