Things to Know Before Choosing the ASUS Zenfone 11 Ultra
The size and weight require consideration before purchase. At 224 grams and nearly 164mm tall, this phone demands two-handed operation for most tasks. Users accustomed to compact phones or those with smaller hands might find the device cumbersome during extended use. Pocket space becomes a concern, as the large dimensions don’t fit comfortably in all clothing.
Software support follows ASUS’s standard policy of two major Android upgrades from the Android 14 base. This means the phone should receive updates through Android 16, which is shorter than the three to five-year commitments offered by some competitors. Users planning to keep their phone for several years should weigh this against the desire for the latest Android features and security updates.
Storage expansion isn’t possible since there’s no microSD card slot. The 256GB base model might prove insufficient for users who capture lots of 8K video, download large game files, or store extensive offline media libraries. Choosing the 512GB variant at purchase becomes important for heavy media users, as there’s no way to expand storage later.
The camera system, while versatile, lacks some features found on competing flagships. There’s no periscope telephoto lens with 5x or 10x optical zoom capabilities that some rivals offer. The 3x optical zoom serves most scenarios well, but photography enthusiasts who frequently shoot distant subjects might want more reach. The ultrawide camera at 13MP has a lower resolution than the main sensor, which could be noticeable when switching between lenses.
Screen resolution sits at 1080 x 2400 pixels, which translates to 388 ppi on the 6.78-inch display. While this provides sharp imagery for most uses, competing devices in this price range often offer higher resolution panels with greater pixel density. Users who scrutinize text or examine photos closely might notice the difference compared to 1440p displays.
The under-display fingerprint sensor uses optical technology rather than the newer ultrasonic sensors found on some premium phones. Optical sensors can be less reliable with wet fingers and typically require the screen to light up during authentication, which can be distracting in dark environments.
