Verdict

The Asus Zenfone 9 with 16GB of RAM and 256GB of storage is a compact powerhouse, featuring a 5.9-inch Samsung AMOLED display with a 120Hz refresh rate and a flagship Snapdragon 8+ Gen 1 processor. Its main pros are the highly portable design, excellent battery life for its size, a unique and effective six-axis gimbal stabilization system for its 50MP main camera, and the useful inclusion of a 3.5mm headphone jack. The primary cons are its limited software update promise (typically two major Android versions), lack of wireless charging, and the absence of a telephoto lens.

Asus Zenfone 9 review – Pickr

Pickr’s review of the ASUS Zenfone 9 describes it as a "compact and confusing" flagship, praising its small 5.9-inch 120Hz display and grippy textured design. While delivering top-tier performance with a Snapdragon 8+ Gen 1 chip, 5G, and a 3.5mm headphone jack, the experience is severely hindered by a critical, persistent focus bug in the main camera and a total lack of wireless charging. Ultimately, the Zenfone 9 is deemed a powerful but frustratingly unreliable device that fails to justify its high-end price tag at launch due to software and camera issues. www.pickr.com.au

Asus Zenfone 9 Review - a mini marvel?

The ASUS Zenfone 9 is a 5.9-inch "mini-flagship" powered by a Snapdragon 8+ Gen 1 processor and a sharp AMOLED display, packing high-end performance into a compact, pocketable frame. Key pros include excellent one-handed ergonomics, a long-lasting 4300mAh battery, and a 3.5mm headphone jack, though it notably lacks wireless charging. The camera system offers impressive 6-axis gimbal video stabilization and autofocus on the ultra-wide and selfie cameras, but it is marred by inconsistent software, a cool color tone, and a tendency for lens flare. While the 50MP main sensor performs well, the device lacks a dedicated telephoto lens and, according to the review, the automatic Night mode does not always activate reliably. Ultimately described as a "mini marvel" for performance-focused users, the Zenfone 9 falls short of top-tier photography, with the review noting that serious photographers may prefer competitors like the Pixel 7 or Galaxy S22. While a strong contender, the lack of optical zoom and inconsistent image processing are noted cons.

Asus Zenfone 9 Review: A small smartphone at a high price

The Asus Zenfone 9 is characterized as a "pint-sized powerhouse" featuring a highly comfortable, compact 5.9-inch form factor, a 3.5mm headphone jack, and top-tier performance via the Snapdragon 8 Plus Gen 1 chipset. Key pros include its near-stock Android software, impressive, stable video recording, and specialized one-handed navigation, making it a rare, high-performance compact device. Conversely, the device suffers from a "mixed" and sometimes "buggy" dual-camera system, which struggles with slow shutter speeds and lacks a dedicated telephoto lens. Other cons include the omission of wireless charging, average battery life, and a 30W charging speed that lags behind many competitors. While offering a premium feel, the Zenfone 9 is ultimately considered disappointing due to its high price point and the presence of these "rough edges". Unless a user is a "small phone superfan" prioritizing one-handed use over versatility, the device is difficult to recommend over alternatives like the iPhone 13 mini.
