Asus Zenfone Max have got 5.5 inch display that works well with sunlight .It comes with Extra-large 5000 MAh battery which claims 36 hours backup.
Upgraded to 1.5 Ghz Octa-core Snapdragon 615 processor and 2GB Ram and 32 GB memory and upgrade with micro-sd to 64GB .The 13 Mega-pixels rear camera is decent and I liked the 5 MP front camera, It runs on android marshmallow 6.01.
The battery in the Asus Zenfone Max stands out.
