I recently bought Asus Zenfone 2. It has attractive features like back camera is 13 Mega Pixels and front cam is 5 MP, 4 Gb Ram, 2.3 GHz Quad-Core CPU, 5.5 inch screen, 16 GB storage. But I love it’s battery backup. It’s battery power is 3000 Mah but after using 3G net, it’s battery lasted 6-7 hours.
So many extra features. Only problem is it’s Non-removable battery, but overall it’s very good phone. I think It’s must have phones. you should buy it.
