People may have a look at the specs of this device and may go for it. But in hand experience and overwall performance really matters.Mi4i is powered by snapdragon 610 which heats a lot, and is not at all comfortable to hold, specially while gaming.The ui lags a lot when internal storage is almost full, which will be a issue because it does’nt have a microsd card slot.Miui 7( based on lolipop 5.0) is preety heavy interface and consumes a lot of free ram although the free ram is 1.2-1.3gb ( for me) .The battery backup is good after few updates, but drainage is lot owing to it’s full hd screen which is really sharp and looks excellent.Its battery backup is almost 1 day with moderate usage( without gaming and internet) .Talking of the camera, the rear camera is a 13 mp shooter and does a excellent job and the front 5mp camera is also sharp in talking selfie.The in hand feel is also good it’s really slim but back is plastic.Overwall very snapy device but there are many devices with same specs and performance and even better than this.So my honest opinion is compare with other devices first.
