Redmi 4 from xiaomi is a mid range device. it has large 5.0 inch display but comes with low resolution of 720p display which is just normal at these days. however it has android 6.0 and adreno 505, despite of this this phone performs too low because it is powered by low performance chipset snapdragon 435. the biggest drawback of this phone is its battery life. the battery drains so fast. the camera of this phone is also average and the auto focus is not so good. otherwise it’s your choice to buy it or not.
