Its powered by immense 3900milli ampere battery, it just comes up with good specs at this price range. Even for a heavy user it easily lasts for 1 full working day. At extended gaming ( being midrange mobile ) it does well. Its a decent mobile and camera shots are also gud at outdoor, coming to indoor camera gives little muddy shots.
At Asphalt8 for highest graphic settings I found minor lag , but at medium graphic settings its again a fluid device.
