I have bee using this phone since December 2017 and the phone still runs smooth with no lagging and other issues. So here is my review after 6 months.The phone has a 5.5 inch full HD display with 178degree viewing angle which is protected by corning gorilla class with 2.5D screen which add a premium look.The phone has a great built quality. Its unibody structure makes it more premium in hand.The phone is a camera beast. MI claims this phone to be their flagship phone. You can shoot awsome potrait in this phone. Thanks to their 12MP dual rear camera which captures splendid images.One of the main feature of this phone is this phone comes with stock android which does not contains any extra applications or bloatwares.The comes with 4gb of RAM and 64gb of internal storage which can be increased upto 128gb with a micro sd card.The phone can handle high-end games like Asphalt 8, Modern Combat series, PUBG, Nova 3 and many other high end games. The phone does get heated while playing games but it is normal and cools down rapidly if you clear the memory and keep it idle for sometime.The phone has a 3300mah battery which is a bit average and runs a full day depending on what purpose you use. The battery saver feature in this phone is a very good compared to other phones I have used. I suggest to carry a powerbank.Overall, I am very much satisfied with this phone. If you have a budget of ₹13, 999 you can simply go for it.
