Hi friends I have been using this mobile over a period of time and I was quite happy with the performance. I am not a gamer and my variant is 4gb ram and 64 rom .Lets start with with bettery performance I am getting and full typical working days without any issue with full connectivity of wifi all the day thanks to 625 chipset. Yes only thing is camera is litle bit dull here but its not big deal because by using 3party aaps like camera 360, open camera and all u will get decent amout of picture u can check some of the sample that has been taken from stock camera .Moving to performance guya really hands off to Xiaomi for improving many things from previous devices . There is no heating usse at all .so for me its big thumb up guys .
