ASUS is really fond of doing tricky stuff. Or shall we say, they are really creative in dealing with their customers? First, 5.2-inch Zenfone Max (ZC520TL) was launched together with the Zenfone 3 flagship devices. Today, we saw a bigger Zenfone 3 Max armed with a different CPU, the ZC553KL. And the laser AF is back.

The first obvious difference is the display. The ZC520TL has 5.2-inch while the ZC553KL has 5.5-inch display.

The second is the CPU that powers the device. The is powered by a 1.25GHZ Mediatek MT6735 64-bit quad-core CPU processor while the ZC553KL has 64-bit Qualcomm Octa-Core Processor Snapdragon 430.

Both battery capacity is the same.

Both has dual SIM cards, but they have different configurations. The newest Max has Micro+Nano config while the old one has both Micro+Micro. These are both hybrid slots. Meaning the second one can act as microSD support.
