Xiaomi is a brand from china which is known to make value for money products. but it doesnot means that products made with good specs also delivers good performane, reliability and durability. I bought mi 4 last year 16gb foraround 2000.
But its price has now came down to around 15000 on Amazon. The biggest problem which I faced was the serious heating problem during heavy gaming and even on normal use.
This major problem also has an ill impact on its 3080 mah battery which was not able to survive even a full day on normal to heavy usage. Heating drains all the battery life. One important thing to note is that 64 gb of it is not easily available on Amazon. I am not against xiaomi and its products.
