Xiaomi Redmi 4 features a 5-inch HD ( 720x1280) IPS display with 2.5D curved-edge glass. There's a non-removable 4100mAh battery. The phone is powered by an octa-core Qualcomm Snapdragon 435 processor clocked at 1.4GHz 3 GB ram and 32 GB internal storage. You get a 13-megapixel rear camera with f/2.0 aperture, PDAF, and an LED flash. There's also a 5-megapixel front camera with f/2.2 aperture. The new Redmi 4 will support 4G and VoLTE. The rear camera has a tendency to capture a lot of noise when there is no direct light source.
