The Asus Zenfone 9 is a more compact and lightweight option with a plastic body, 5.9-inch screen, and jacks for headphones. It offers a good still photo and video quality in its camera and solid battery life. If you prefer a larger phone with a premium glass body, the OnePlus 11 has a 6.7-inch screen and delivers very high-quality photos and videos with its camera. It has slightly longer battery life as well. The OnePlus 11 provides a higher screen resolution and a faster processor, which translates to superior performance. Both have OLED displays with high refresh rates, but the OnePlus 11's screen is brighter and has a variable refresh rate feature. Although the Zenfone 9 is generally pricier, the OnePlus 11 could provide better value with its larger screen, better camera quality, and higher performance if you can go without a headphone jack and a slightly smaller form factor. Both run Android and offer similar features like 5G connectivity and fast charging capabilities. Give Feedback

Android Authority

Robert Triggs | March 2023
"The Asus Zenfone 9 is a compact device that still packs more than enough power under the hood. It's compact size, Bluetooth and audio features (including a headphone jack!), and hardware gestures combine to offer a package that does enough differently to warrant your attention."

Will Sattelberg | April 2023
"The OnePlus 11 isn’t a perfect device, but it’s another big step in the right direction for the company. A great display, incredible performance, and some of the best battery life I've ever seen on a phone helps make this one of the best OnePlus devices in recent years."

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”.
