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%.

Stainless steel frame
crafted in a 40-step process

Mi 4 is not just a leading-edge smartphone, it’s a work of art. A forged stainless steel frame and
aluminum-magnesium alloy mid-frame combine to make an exceptionally sturdy structure, while the
ultra-thin screen and beautifully textured back cover make Mi 4 a joy to hold. The next-generation Mi phone
is truly the perfect blend of style and substance.

Turning steel into art

The frame of each Mi 4 handset is the result of 193 carefully designed high-precision
manufacturing processes. Using advanced engineering techniques and a keen artistic sense, we
transform 309 grams of raw steel into a 19-gram masterpiece over the course of 32 hours of
processing, crafting, and polishing.

Probably the most sophisticated manufacturing
process for any smartphone, ever.

The Mi 4 frame alone requires 193 separate manufacturing processes to produce. The major
steps include forging, molding, eight stages of CNC milling, micron sandblasting, and PVD and
nano-grade Anti-Fingerprint (AF) coating. No fewer than 342 technicians work
on each phone, to ensure every last detail is technically and aesthetically perfect.

  • Eight CNC milling steps
    create the chamfer edges

  • Sandblasted till perfectly smooth

  • Deep, lasting color
    Ultimate fingerprint resistance

The world’s first 9-layer IMT back cover
with 0.06mm grain

Made up of 9 layered membranes, the back cover is just 0.8mm and features a grating
pattern, made up of intricate lines just 0.06mm thin. This has a beautiful tactile feel, and a subtle
visual effect that changes when you look at it from different angles. The multi-layered
membrane construction is scratch and fingerprint-resistant. The only way to combine so many
thin layers together was by using In Mold Transfer (IMT) technology – the first time this
technique has been used in a mobile phone cover.

Enhanced with an aluminum-magnesium alloy

Strength and lightness don’t always go together. So we put serious engineering thought into creating a body
structure that balances these 2 attributes. Our solution? A lightweight and stable aluminum-magnesium
mid-frame protected by a more robust stainless steel outer. An edge-protecting membrane inserted between the
screen and the external frame absorbs shocks and reinforces the four corners of the phone, and a conductive
graphite thermal film improves cooling by rapidly dissipating heat.

  • Aluminum-magnesium alloy mid-frame

    The magnesium alloy contains two-thirds
    aluminum and one quarter steel.
    It is the lightest usable alloy that has
    sufficient physical strength.

  • Reinforced drop-resistant corners

    The reinforced edges are designed not to
    deform easily if the phone is dropped,
    reducing the chances of screen damage.

  • Edge Coating for extra protection

    A 0.05mm-thick Edge Coating layer under
    the screen glass acts as a shock absorber,
    reducing the energy transmitted from the
    frame to the glass in the event of an impact.

Elegance comes from attention to detail

Every component of Mi 4’s body has a minimalist elegance about it. The headphone jack and the
infrared emitter sit in the middle of the phone’s top edge. Two metal buttons and the micro-SIM slot
are incorporated into the side edges. A micro-USB port and speaker holes are found in the bottom
edge. Each of the 45 speaker holes is CNC-milled to a diameter of precisely 0.6mm.

Excellent grip

The display measures 5 inches diagonally, and the
body is just 6.85cm wide. The frame is made entirely
of metal, yet the whole phone weighs just 149g.
With its ultra-thin display, perfectly balanced body,
smooth sandblasted finish, and back edges curved to
fit the palm, Mi 4 sits perfectly in your hand.

Protective covers

A beautiful protective flip cover is available for Mi 4, made of smooth faux leather
and lined with microfiber to protect the screen against scratching.It comes in 5
elegant colors: sky blue, red, green, white, and black.
A protective cover in genuine cowhide leather is also available as an accessory,
in a range of stylish retro colors.

From selfies and group shots to food photography, capture precious memories as images and video, wherever you go. People increasingly take more pictures than calls on their phone, and Mi 4 incorporates the very latest in camera technology to enhance your photography experience. It’s blindingly quick – quick to activate, quick to focus and quick to take the shot. And with its combination of robust design and cutting-edge hardware and software, it’s the perfect on-the-go travel companion.

Autofocuses in 0.3 seconds

Most smartphones require 0.6 to 0.8 seconds to focus – that’s critical time lost when you’re shooting on-the-go. But Mi 4 features an advanced closed-loop focus system which is much faster than conventional solutions. Traditional autofocus systems need to move the lens through its whole focal range to determine the point of focus. But the closed-loop system can communicate the motor location to the focusing system,

 Shoot first, focus later

Blurry photos? Not a problem! Now you can adjust the focal point even after you’ve taken the photo with Magic Focus. This allows you to switch the area of focus in the photo from one object to another retrospectively. Depth of field and bokeh effects can also be adjusted afterwards. With unlimited possibilities, it’s time to get creative.

Hit a moving target

Tracking autofocus locks on to fast-moving objects

Whether you’re shooting at a sports event or tracking a moving animal, how do you capture fast movement on your phone? With Touch-To-Track technology, it’s simple. Gently slide your finger to select and lock on to the object you wish to track. Mi 4 will then automatically adjust the focal point and calculate the exposure. It’s a function you might previously have found only in professional cameras but with Mi 4, it’s right there in your pocket.

Rapid-fire HDR burst mode

10 shots per second, hardware-level previews in real time

While most HDR shots are software-based and involve stitching pictures of different exposure levels together, Mi 4’s hardware-level processing uses a staggered electronic shutter exposure technique to give you HDR in every single frame.
