Product Features

Crafted to perfection

 

Snapdragon 801 2.5GHz, Adreno 330 GPU, 3GB LPDDR3 RAM, 16GB eMMC 5.0 Flash, 5" IPS Full HD 441 PPI, Gorilla Glass OGS, 13MP f1.8 rear, 8MP f1.8 front 80° wide camera, 3080mAh lithium-ion battery, Quick Charge 2.0, MIUI 6

 

Qualcomm Snapdragon 801 quad-core 2.5GHz processor

 

Mi 4 is built around Qualcomm's Snapdragon 801 chipset and its four 2.5GHz Krait 400 processor cores, which gives you 14% more computing speed. Nearly 2 times faster in image processing than its predecessor, it has an unrivalled ability to handle several complex tasks while maximizing battery life, thanks to its super energy-efficient Hexagon DSP core.

 

Adreno 330 GPU

 

The 3D rendering capabilities of a gaming console

 

The Adreno 330 GPU supports advanced graphics APIs, including OpenGL ES 3.0, OpenCL,Renderscript Compute and FlexRender. It can render highly complex graphics at lightning speed, thanks to Unified Shader Architecture and FlexRender's fast rendering technology. Unified Shader Architecture dynamically adjusts the allocation of computing resources depending on the type of image, with independent adjustment of pixel and vertex shaders. FlexRender's technology dynamically chooses between immediate and deferred rendering modes, which enables the Adreno GPU to deliver images in games faster and more efficiently.

 

Energy-efficient DSP core

 

The latest Hexagon QDSP6V5A DSP technology makes video and image-based apps particularly energy-efficient. As a result they can run for longer and drain less battery power.

 

Quad-core reduces power wastage

 

High performance mobile (HPm) technology and aSMP dynamic CPU power-supply control can manage the frequency and voltage of each core chip in the CPU independently based on the application usage scenario, in order to reduce unnecessary power wastage. Quick Charge 2.0 accelerated charging technology reduces charging time by 75%.

 

High color-saturation with 84% NTSC gamut

 

Mi 4 features a high color-saturation Sharp/JDI display, with 17% better overall color saturation for a richer viewing experience. Whether you're looking at photos, watching videos, or using exciting apps, Mi 4 delivers vivid colors.

 

13MP Sony High-Speed Camera

 

Great photos in milliseconds. Sony's IMX 214 13MP Exmor RS stacked image sensor collects more light through a 6-element lens and autofocuses in just 0.3 seconds. With a large f/1.8 aperture, Mi 4 delivers great low-light performance and bokeh effects. Give Magic Focus mode a try - just snap an image and choose your point-of-focus later. It's magic!

 

MIUI 6

 

Discover new functions, shortcuts, customizations and animations embedded within MIUI 6. Each swipe, pinch and flick is co-developed and upgraded regularly, based on improvement suggestions from some 100 million active MIUI users worldwide.

 

Use your phone as a remote control

 

Mi 4's in-built infrared remote control function supports transfer protocols with infrared receiving equipment. The Mi remote control app can be used to operate televisions, air-conditioning units and a vast array of other home appliances. The app currently supports 2,853 devices, and more are being added all the time.
