At a price of Rs. 13,999, the Xiaomi Mi3 has a blazing fast 2.5GHz quad-core Qualcomm Snapdragon 800 processor coupled with 2GB of RAM and 16GB of on-board memory. Unfortunately, you won't able to expand the internal memory, since the device does not support a microSD card slot. Naturally, this is a major negative point of the Mi3.
Talking about the experience, the Mi3 is a pretty fast device. We haven't faced a single lag in our brief testing. The Snapdragon 800 chipset seemed to be fast and zippy.
On the connectivity front, the phone has an array of connectivity options: a fast 3G support, 2G, Bluetooth V4.0, FM Radio, and much more.
