Asus Zenfone 9
Verdict
A compact and powerful phone with impressive battery life but struggles with camera accuracy.
Key specs
Critic consensus
“Setting out to make a proper flagship in a tiny body, Asus did a lot of things right with the Zenfone 9, with only minimal compromise. If we have to point out its missteps, those will include the lack of wireless charging (all the bar phones above have it, and so does the Flip) and the missing telephoto camera. These are both more or less understandable omissions, given how both take up valuable space. The rather slow Night mode implementation had to be mentioned, but it's more of a niggle in the absence of other flaws and one that could potentially be fixed in an update.”
“The Zenfone 9 is a powerful upgrade compared to the predecessor. It is unfortunate that Asus will probably only deliver two large Android updates to its compact smartphone.”
“As a full package, it doesn't truly, fully deliver on the dream of having all of the features every top-of-the-line device out there has, just in a small package. There are still compromises. And that's why we can only cautiously recommend the Zenfone 9. We think you should look at it side-by-side with the Galaxy S22, and pick the one that has the most upsides and least downsides for your personal use case.”
“It might not look like a glitzy flagship phone, but there are a lot of goodies in this little package.”
Watch before you decide
In Depth
Design
The Zenfone 9 stands out with its compact size and unique back. The feel is cool and textured, ensuring a sure grip. Its small stature makes it easy to handle with one hand, unlike much larger phones today.
The phone forgoes glass at the back in favor of a soft, rubber-like finish. This design choice is both about comfort and practicality, offering durability while resisting fingerprints. It’s available in multiple bold colors to suit different tastes.
Experts note, “It’s remarkably lightweight and grippy, admittedly different from other premium materials, but it gets the job done in a cool way.” While the texture avoids fingerprints, the back’s finish can pick up scuffs over time but remains durable overall.
Display(s)
The Asus Zenfone 9’s 5.9-inch AMOLED display combines Full HD+ resolution with rich colors. You’ll appreciate the screen’s brightness, even on sunny days, ensuring clear visuals outdoors.
With a 120Hz refresh rate, every swipe feels smooth and seamless, making your interactions swift and enjoyable. It’s a treat for watching videos or playing games.
While the display excels at bringing colors to life, it is smaller compared to larger smartphones. This smaller size may make tasks like watching detailed scenes a bit challenging.
Performance
The compact phone runs on a powerful Snapdragon 8+ Gen 1 processor. This latest chip from Qualcomm ensures you can multitask and enjoy gaming without interruptions, even on this smaller-than-usual device.
Reviewers highlight its “Herculean performance,” though it can heat up during intense tasks. This can lead to throttling, which means the phone might slow down a bit under extended heavy use.
The phone’s cooling system, though improved, can’t match larger models. If you prefer a device that never compromises on performance, be aware that the compact design imposes some limits.
Software & Storage
The Zenfone 9 runs on a near-stock Android UI that’s intuitive and user-friendly. You’ll find it fast and responsive, keeping close to Google’s original design.
Reviewers appreciated the “clean, functional UI,” which is easy to navigate (NextPit).
However, the phone’s software support is a drawback, offering only two years of updates, which might limit its long-term appeal.
Cameras
The camera setup on this phone is designed to impress with its 50-megapixel wide camera paired with a powerful gimbal stabilization system. This feature allows you to capture ultra-steady video and clear low-light shots. The additional 12-megapixel ultra-wide lens offers a broader perspective for varied scenes.
While the gimbal is great in theory, reviewers like those at NextPit and others have pointed out its struggle with focus inconsistencies in certain lighting conditions. Asus promises strong video stabilization up to 8K, but stabilization truly excels at lower resolutions like Full HD. Experts highlight how this makes video recordings smooth even on bumpy rides.
If you’re a photography enthusiast chasing clarity, this main camera offers excellent shots with the right light, though it might need a little patience to focus perfectly every time.
Battery
Despite its compact size, the Asus Zenfone 9 is equipped with a 4,300mAh battery, a surprising advantage that ensures all-day usage. Experts acknowledge it can last well beyond 24 hours on a single charge. This presents peace of mind to those who dread regular charging rituals.
One notable downside is the missing wireless charging, a convenience common in many premium phones but absent here. You’ll rely on the included 30W charger, which is spaciously quick but not the fastest available. According to reviewers, “This absence baffles some,” especially considering the device’s high-performance level.
Audio
The Zenfone 9’s stereo speakers deliver a loud and immersive audio experience, ideal for watching movies or gaming. “Tuned by Dirac, the audio boasts volume and artificial bass enhancements,” experts share. This ensures you won’t need additional speakers for rich sound.
For calls, the Zenfone 9 includes a 3.5mm headphone jack. You’ll appreciate clear voice capture during calls and while recording videos. The inclusion of a headphone jack is a bonus for those who prefer wired audio, enhancing your media and call experience.
Whether using Bluetooth headphones or wired, the Zenfone 9 ensures quality sound, making sure your calls and entertainment are as enjoyable as they are clear.
The Bottom Line
This phone stands out with its compact size, making it easy to use with one hand and perfect for those who prefer smaller devices. The 5.9-inch display is bright and responsive, ensuring a smooth experience while browsing or gaming.
It packs a punch with its top-tier processor, delivering fast performance for everyday tasks and intense gaming sessions. The battery life is remarkable for its size, lasting well over a day, minimizing the need for frequent charges.
While the design is distinct and easy to grip, the camera system, despite its stabilization features, often fails to achieve sharp focus and produces inconsistent results through software glitches.
If photography isn’t your priority, this phone remains an excellent choice for its performance and form factor, though camera enthusiasts may want to explore more reliable options.
