Xiaomi is not though a old company like Samsung and Sony but it is beating all this company’s in terms of there specifications and price range.If you are looking for an good smartphone under INR 15000 then just go for it.
PROS-
1.It has a perfect metal body with 5.5" screen which feels good
2.I hat humangeous battery life of 4050 mah
3.Adding a 3GB RAM to the processor, makes it unbeatable and best in its category
CONS-
1.MIUI(Software UI that phone comes by default) takes a lot of RAM. Though it is good in looks and usage, but has a high memory consumption. Its better to opt for 3GB model then the 2GB one
2.Android updates are not so fast comparing to the Moto which is also in the competition.
