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 S25 FE

The S25 FE adopts the flat-edge design language of the S25 series, giving it a modern, premium look. However, build quality concerns have emerged, with the polycarbonate back and Gorilla Glass Victus scratching more easily than expected.

Flat-edge design mirrors the mainline S25 series — it looks like a flagship from the outside

Display

ASUS Zenfone 12 Ultra

The 6.78-inch Samsung E6 AMOLED panel delivers 2,500 nits peak brightness with LTPO adaptive 1-120Hz (144Hz for gaming). Vivid colors and excellent outdoor readability are let down by FHD+ resolution at a price where competitors offer QHD+, and poor minimum brightness.

2,500 nits peak brightness with LTPO 1-120Hz and 144Hz gaming mode — vivid and responsive
Same display panel as the Zenfone 11 Ultra — no improvement whatsoever year-over-year
Only FHD+ resolution at EUR 1,099 — competitors offer QHD+ at this price tier

Samsung Galaxy S25 FE

The 6.7-inch Dynamic AMOLED display is one of the S25 FE's strongest features. Samsung's display expertise shines here, delivering flagship-quality visuals at a mid-range price.

The FHD+ AMOLED display is vibrant, sharp, and smooth at 120Hz — hard to fault for $649
Peak brightness is sufficient for outdoor use, though not as high as the mainline S25 series
HDR content looks excellent — the display punches well above its price bracket for media consumption

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.

5,500mAh battery delivers excellent all-day endurance — close to two days for light users
65W wired charging reaches 77% in 30 minutes with Qi 1.3 wireless charging support
Same battery specs as Zenfone 11 Ultra — 65W charging falls behind competitors offering 100W+

Samsung Galaxy S25 FE

The 4,500mAh battery provides solid all-day endurance. The less power-hungry Exynos 2400 chip actually helps battery life compared to the more powerful Snapdragon alternative.

Battery comfortably lasts through a full day of moderate use — a strong point for the FE
The Exynos 2400's lower power draw actually benefits battery life compared to Snapdragon devices
25W wired charging is adequate but increasingly dated compared to competitors
15W wireless charging is included, which is a nice-to-have at this price
