Detailed Comparison

Design & Build

ASUS Zenfone 12 Ultra

Sleek matte glass back with ultra-narrow bezels and IP68 water resistance. The rare 3.5mm headphone jack is a welcome differentiator. However, the design is nearly identical to the Zenfone 11 Ultra, and the large 6.78-inch form factor disappointed fans of ASUS's formerly compact Zenfone line.

Retains the rare 3.5mm headphone jack — almost unique among 2025 flagships
IP68 water resistance with Gorilla Glass Victus 2 and sleek matte glass back
Nearly identical design to the Zenfone 11 Ultra — barely iterative year-over-year
No charger included in the box despite the premium EUR 1,099 price

Samsung Galaxy Z Flip 7

The Z Flip 7 maintains Samsung's iconic clamshell design while refining every aspect. It's slightly thinner when folded, the hinge feels more robust, and the larger cover screen transforms how you interact with the phone closed.

Sleek clamshell design remains eye-catching and pocketable — it's a conversation starter everywhere you go

Battery Life

ASUS Zenfone 12 Ultra

The 5,500mAh dual-cell battery delivers excellent all-day endurance that approaches two days for lighter users. 65W wired charging goes from 0-77% in 30 minutes, and Qi 1.3 wireless charging is included. Battery specs are unchanged from the Zenfone 11 Ultra.

Battery life easily lasts 24+ hours with mixed use — the best endurance of any Samsung flip phone
The Snapdragon 8 Elite's efficiency is a key factor in the improved battery performance
25W charging is adequate but not impressive by 2025 standards
Heavy cover screen use can drain the battery faster than expected due to the always-on nature
