This model (AKA Asus ZC520KL) outstrips its mother model's battery power (3300mAh) by a huge margin, this time relying on a 4100mAh battery pack with reverse charging support and Asus's PowerMaster battery management technology suit, and it picks up the popular (as of its release) dual-rear-camera trend, touting a 13-megapixel PixelMaster main cam alongside a 5-megapixel wide-angle secondary cam on its rear. It also takes a huge blow in the performance department, supplanting the Zenfone 4's 2.2GHz eight-core engine for a basic-level 1.4GHz quad-core Snapdragon 425 chip.

Also known as: Asus ZC520KL, Asus Max Zenfone 4 ZC520KL.
