Sees the Xiaomi Redmi Note 4 just got released in HK. HK price seems a bit high with $1499 considering that the China price is just RMB 899 (OK, that is the basic version with 2Gb RAM and 16Gb, the 3Gb/64Gb version is RMB 1199 ~ $1400). Seems the 16Gb isn't released in HK.
The 4100mAh battery should really make it run for quite some time.
