Asus teases new Zenfone smartphone release with two major upgrades planned

Asus has already unveiled several new devices this month, having brought a bumper crop of ROG, Vivobook and Zenbook devices to CES 2025 in Las Vegas. Now, it has officially confirmed that it will soon be updating the Zenfone series with a direct successor to last year's Zenfone 11 Ultra (curr. $899.99 on Amazon).

Asus is keeping quiet on many details for now, including what the device looks like. However, it has revealed that it will be fully unveiling the Zenfone 12 Ultra on February 6 during an event scheduled to start at 06:30 UTC. As the image below hints, the Zenfone 12 Ultra will be capable of shooting 4K videos for extended periods with autofocus and subject enabled. Other technical details about the device remain unconfirmed.

With that being said, we can make an educated guess about the Zenfone 12 Ultra based on its predecessor's origins. In short, Asus used the ROG Phone 8 as the basis for the Zenfone 11 Ultra. Consequently, the Zenfone 12 Ultra will likely share almost all its specifications with the ROG Phone 9, which we reviewed a few months ago with a Snapdragon 8 Elite chipset and a 6.8-inch AMOLED display that combined a 185 Hz refresh rate with over 1,600 nits full panel brightness.
