Recently, I had the chance to get my hands on the all-new Zenfone 9 by ASUS. After unboxing it, I was impressed by the powerful hardware, ample battery capacity and sleek, compact form factor of 5.9 inches. It comes in 4 colors – Sunset Red, Starry Blue, Midnight Black and Moonlight White – all with a black anodized aluminum frame, and a plastic back that is soft to the touch.

The Zenfone 9 is a powerhouse with its Snapdragon 8-Plus generation one chip, making it an ideal choice for gamers. It's also able to support a 30-watt charger so users can get their devices up and running in no time. Additionally, the phone is equipped with software features that help save energy and ensure the battery life is optimized.

The screen resolution is impressive and is rated at 400 nits indoors and 800 nits outdoors, going up to 1100 nits while watching HDR content. The speakers are also good, albeit with slightly thicker bezels on the top and bottom.

The cameras on the Zenfone 9 are a mixed bag. It is equipped with a Sony IMX766 main camera and IMX363 ultra-wide camera. While the main camera is satisfactory in most cases, it is prone to overexposure and underexposure at times. The ultrwide camera performs significantly better in low light conditions and is much more responsive when capturing quick shots. On the other hand, the front camera is quite impressive and produces sharp images consistently.

The only downside to the Zenfone 9 is its price tag of $799, which is quite steep for a device of this size. That being said, ASUS is offering two year software updates and support as well as some of the great hardware features, making the product well worth its price.

Additionally, though it does not have wireless charging, it does come with a 30-watt charger which is quite fast for a device of this size.

The Asus Zenfone 9 has an impressive display with plenty of features to enjoy. The 5.9 inch display fits nicely in the hand and offers a 120 Hz refresh rate and 400 nit brightness when indoors. Outdoors, the brightness will go up to 800 nits, and for HDR content, go up to 1100 nits. It also offers a touch sensitive fingerprint sensor and a wide range of adjustable settings to customize your experience. In terms of battery life, while it won't achieve the two day battery life that Asus claims, it can give a comfortable full day of use with 8-10 hours of screen on time. Charging is fast too, thanks to the 30-watt charger that comes with the Zenfone 9, making it an all-around great device with plenty of features to enjoy.

An In-Depth Review of the Asus Zenfone 9 Camera System

The Asus Zenfone 9 is an impressive device for its size, boasting a powerful chip, a huge 4,300 mAh battery and a headphone jack. The camera system is especially noteworthy, as it features a main lens from Sony's IMX 766 series and a wide-angle IMX 363 lens. The main lens is par with other mid-range sensors, with one downside being that it lacks in terms of exposure consistency. The ultra-wide lens has great performance in well-lit areas, but stumbles a bit in low light. The front camera, however, is very good with sharp and consistent results. While the camera system is not the best available, it is still able to take great shots.
