I am using Xiaomi Redmi Note 4 from last 2 years
Good battery life you can use the phone for 1 day if you are using internet or playing games on this phone.
Images clicked from camera is very crisp an clear
Processor has lightning speed
Touch is smooth and responsive
and the best thing I like about this phone is it has an option where in you can control apps which can use internet and which should not use internet as per your wish, mostly in other phones you dont get options eg: face book uses internet on other phones until not logged out, however on Xiaomi Redmi Note 4 you can choose whether it should use internet or not.
As per my sugesstion buy it, use it and enjoy it.
