Performance
Under the hood, the Mi 4 LTE packed a Qualcomm Snapdragon 801 chipset, paired with a quad-core 2.5 GHz Krait 400 CPU and an Adreno 330 GPU. With 3GB of RAM and 16GB of internal storage, albeit non-expandable, the phone delivered seamless multitasking and robust performance across various applications and games. Operating on Android 4.4.3 KitKat with MIUI 5, the device provided a responsive and user-friendly interface, though MIUI's customization was a polarizing factor among users who either loved its flexibility or yearned for vanilla Android simplicity.
