I was really very much confused about which mobile to buy in the price segment of 10-12k but after Xiaomi launched redmi note3 at a price tag of 10k and 12k, I thought this was the perfect mobile.
I need to buy because the features are too awesome and the battery too was excellent and with my personal experience of 2 months I can guarantee you that once you charge it completely it will work minimum for 2 days.
Also, the back and front camera is excellent only one con about this mobile is that during charging the phone gets somewhat heated up but in regular use it does not heat up. At last I would say at a price tag of 12k with 3 gb ram xiaomi has launched a real flagship mobile.I personally recommend you to buy this mobile in place of moto g4 or Lenovo zuk z1.
