Redmi Note 4 is supercharged by Snapdragon 625, an octa-core processor chip that uses the most advanced 14nm FinFET technology. It is 20% more power efficient than Redmi Note 3, and is bound to put more power in your pocket. Expect a smoother gaming experience with up to 4GB RAM and 14nm FinFET technology. It is this winning combination that delivers more thermal reduction and greater sustained performance. Also comes with up to 64GB of storage. Redmi Note 4 uses a noise-eliminating CMOS sensor with backside illumination ( BSI) and larger pixels to give you stunning images even in low light.
It also comes with Phase Detection Autofocus ( PDAF) for 0.1s ultra-fast focusing, which is especially useful for shooting moving objects.
