Redmi note 4 is the king of all smartphones in the price range of 15000 ruppes. In this budget we get an snapdragon 625 chipset with 14nm technology which is extremely good in this price range. This chipset performs very smoothly and its based on 14nm technology which it very power efficient also. This phone has got an huge 4000mah battery which means that the charge of the phone will last easily for thae whole day. It has also got an 13 MP camera which has PDAF and it clicks photos very quickly in 0.1sec only. It has also got 4gb ram which allows you to play games more efficiently. The phone has also got an I R blaster with which you can use your redmi as a remote control for TV etc. I am personally using redmi note 4 and its the best smartphone I have ever seen in this price range.
