Hello friends, I am Sumedh I share my experience about my redmi note 4 mobile. I bought redmi note 4 before 4 months. Battery backup of my mobile is very very long time. I used full battery of mobile upto 14 hr with internate. It’s screen curved in the middle so that it looks very attractive. And back look is also best and finger print scanner is there so u can easily unlock it. One best feature is given to this mobile is IR sensor, so that you operate your all smart TV and other smart appliances from your redmi note 4 mobile.
