Personally I don’t like xioami phones because it is Chinese product. My dad recently bought this phone which is average phone. Redmi Note 4 is worst phone ever because it takes 3-4 hrs to full battery.
Specifications:
battery: 4100 mAh li-Po, but it takes 3-4 hrs to full battery
Display: screen viewing is average. 5.5" inch HD(1080*1920 Pixels).
RAM: 3GB Snapdragon 625 which is ok.
Camera: 13 MP 1080p, camera is not good as I expected.
IT supports VOLTE(Voice Over Long Term Evolution).
