Hii friends, I am using this phone from last 2 years. This phone have very good battery backup and have a 5000mah battery. And the camera is 16 and 8 mp . Photos are very clear .and the processor is quad core but it act smartly on multitasking. Play big file games in this phone without any problem. And don not hang but sometimes there is a rarely chances of hangup. And the touch is smooth and there is a fast charging process .Once you charge the phone it last long for a whole day. I suggest you to buy asus phones now in the market zenfone 4 is available .This is available with more features . You must have buy it once and try out the features and also the price is low as campare to other products and relability is more
Thank you
