  • The Xiaomi MI3 smartphone features a 5-in. IPS TFT-LCD display with FHD (1920 x 1080) resolution, 16M colors, and a capacitive touchscreen with anti-glare overlay. It runs the Android 4.2.1 “Jelly Bean” operating system with Xiaomi’s proprietary MIUI (“Me You I”) user interface on a 1.8 GHz quad-core NVIDIA Tegra 4 processor with 2 GB RAM. It also features 16 GB of internal memory (no microSD slot for additional storage) and two cameras. The rear-facing 13 MP BSI (Sony Exmor RS) CMOS camera has autofocus, dual- LED flash, HDR, and 1080p HD video capability. There’s also a front-facing 2 MP webcam. Connectivity is provided by dual- band WiFi 802.11a/b/g/n (2.4 GHz & 5 GHz), WiFi Mobile Hotspot, WiFi Direct, WiFi Display, Bluetooth 4.0, microUSB 2.0, NFC, DLNA, FM radio, and GPS/GLONASS. Sensors include a 6-axis MEMS gyroscope & accelerometer, 3-axis electronic compass, ambient light/proximity sensor, and pressure sensor. The Xiaomi MI3 is powered by a 3.8 V, 3050 mAh Li-polymer battery. (Battery life is unknown.)
