Asus quietly reveals the ZenFone 4 Max in Russia, with dual cameras and a massive 5,000mAh battery
Those of you with a good memory may remember the ZenFone 4 name from a few years ago. In 2014, Asus was using screen sizes for its naming convention when it released the ZenFone 4, 5, and 6 with respective display sizes in inches. Here we are three years later, and Asus has long since switched to a more conventional chronological naming scheme for its ZenFone line. Following on from last year's ZenFone 3 series of phones, the first in the 2017 ZenFone 4 range has been revealed on Asus' Russian site.
