ASUS Zenfone 12 Ultra vs Samsung Galaxy S26 Ultra

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 S26 Ultra

The S26 Ultra is the thinnest (7.9mm) and lightest (214g) Ultra ever, ditching the titanium frame in favor of Armor Aluminum. Rounder corners improve the hand feel significantly. Gorilla Glass Armor 2 protects the display. The design change from titanium to aluminum is divisive — some see it as a downgrade, others say it doesn't matter in real use.

• At 7.9mm thin and 214g, this is the thinnest and lightest Galaxy Ultra ever — noticeably more comfortable to hold than the S25 Ultra
