Street price ÷ months of safe use remaining — the number that makes cheap short-lived phones expensive, and well-supported ones cheap.
93% above the $600–900 median ($14.81/mo, dying phones excluded)
Our verdict
A big-screen flagship that brings ROG-grade internals and a triple camera to a more mainstream design, but the move from compact Zenfones to a large body disappointed fans and updates are limited.
Pros
- Flagship Snapdragon 8 Gen 3 with up to 16GB RAM and a large 5500mAh battery
- Bright 144Hz AMOLED with strong color accuracy and 2500-nit peak brightness
- Versatile triple camera with gimbal-stabilized main and a 3x telephoto
- Fast 65W wired plus 15W wireless charging and IP68 durability
Cons
- Only ~2 OS upgrades and 4 security years, short for a flagship in this price class
- Abandons the small-phone identity of prior Zenfones — now a large 224g device
