talking about the phone it is a pretty good.with snapdragon 800 chipset which is a quadcore processor with 2 gb of ram.it come in 2 variants i.e. 16gb and 32gb.
now talking about the terms of performance..this is one of the android device ive seen in terms of performance.there is no issues of laggingness or anything like that.everything just run fluently on this phone.
talking about the battery life it really disppointed me it has a 2300mah seal pack battery.you have to charge this device everyday if u forgot to charge.next day youll find this device dead.
