Asus Zenfone Max have the two variant one is of 10k and other is the 13k the features are same but the only differnce is the 10k phone has 2GB Ram and 13k phone has 3GB Ram and other features in both variant are the same.The phone has 5000 MAH Battery which is too good in this range.
but the negativity is that the camera is not so good and the screen display is only 720p and the processor is not good.
only the battery life is good if you want to buy the phone you can also buy the redmi note 3 which has the more features only if you buy for Marshmallow or for the look than you can buy it but from my point of view I was not excited for this phone instead I buy Redmi Note 3 it has more features than the Asus Zenfone Max.
I wish that Asus Zenfone 3 will be good and have the good features.
