I have used redmi note 4 for 4 monyhs and I found that this smartphone is very much priceworthy .
its good in following things-
1- RAM- 4 gb ram is very good in this price range.
2- INTERNAL MEMORY- 64 gb memory is ok fo smartphone.
3- BATTERY - it performs well for more than 2 days if used normally. battery is 4000 mah.
4-SCREEN- colours are good .
and except this there are features like mi remote, slow motion in camera, light sensitiveness which works quite well.
one thing that is not very good that is camera . in sunlight pics are good but in night both cameras are bad.
