Asus Zenfone 11 Ultra review: specs, battery & used prices

Summary

The Asus Zenfone 11 Ultra is Asus's 2024 pivot to big phones: a 6.78-inch OLED at 144 Hz, the Snapdragon 8 Gen 3, a 5,500 mAh battery, and a camera system with gimbal-style stabilisation. It launched at $899 for the 12/256 GB configuration, which now trades used for around $735 — a modest discount that our resale score of 100/100 says will persist.

Display and design

The 6.78-inch OLED pairs a 144 Hz refresh rate with a 2,500-nit peak, scoring 93/100 on our screen-quality axis — among the best displays in the catalog at any price. At 225 g with a compactness score of 66/100, it is unmistakably a large phone; IP68 protection is standard.

Performance

The Snapdragon 8 Gen 3 delivers a gaming score of 54/100 — comfortable sustained 3D performance at high settings — with Asus's gaming suite (AirTriggers, bypass charging) carried over from the ROG line. The support window is the catch: two years of updates means the runway is already closed for a 2024 model.

Camera

The triple system combines a 50 MP stabilised main sensor — with gimbal-style stabilisation processing — plus ultrawide and 3x telephoto modules, shooting to 8K at 24 fps. Our camera score of 48/100 is respectable mid-catalog, with the main sensor the clear strength.

Battery and charging

The 5,500 mAh battery earns a 50/100 battery-life score, with 65 W wired charging at 46/100 — under an hour for a full charge.

Verdict

The Zenfone 11 Ultra at around $735 used is a 93/100 display with flagship performance at upper-mid-range money — for buyers who accept a closed update window. Long-time Zenfone fans should note the compact identity ended here; the Zenfone 10 is the last small Zenfone, and the gaming-oriented ROG Phone 8 Pro shares the platform with faster refresh and triggers.
