This smartfone is awesome with 5000 mah battery.This is having 1.3 ghz octacoreprocessor which actually runs cool.Along with 2 gb ram makes this product capable of handling many of the high end games and apps.THERE IS NO HEATING ISSUES.I am using this phone for about 1 year, I cant notice any heating issues.If I play asphalt 8 for more tham 1 hour, then small feat will be produced but it is very promising than that of old asuse having intel processor because of the new snapdragon processor.
