A display of perfection 5" Sharp/JDI Full HD display
You interact with Xiaomi Mi 4i entirely through it's stunning 5" display, which is why we added 5 different pixel-level innovations to produce clear, vivid images that look amazing from any angle and in any situation - even under bright sunlight. Using it is pure delight. We're convinced it is one of the best displays around.

Only Flagship phones have 1080p Full HD 2.25x more pixels than 720p
With a 1920x1080 resolution, the same resolution as several 49" Full HD TVs, Mi 4i offers ultimate clarity by condensing millions of pixels on a 5" display. It has 2.25 times more pixels than 720p and an overwhelming 441 pixels per inch. That's even higher than the iPhone 6 Retina HD display which has 326 PPI. So images have a distinct clarity whether you're browsing the web, reading e-books or watching a movie.

Maximum readibility in sunlight
Sunlight Display adjusts contrasts for each pixel in real time
Maxing out on brightness levels under sunlight has a limited effect on readability and quickly drains battery. The latest Sunlight Display in Mi 4i uses hardware-level technology to adjust the contrast of each pixel in real time, so images are less affected by glare. This improves content clarity significantly, so the display actually appears as clear as day.

Performs with flying colors
Ultra-high color saturation, 32% more vivid than the iPhone 6
Let Mi 4i show off its true colors with a splendid range covering 95% of the NTSC palette. With redder reds and bluer blues, this ultra-high color gamut takes on a saturation and vibrance that far surpasses other phones.

Wide 178° viewing angle with IPS technology
Looks stunning from any angle

Phones are not always held perpendicular to our faces, that's why the Sharp/JDI display on Mi 4i has an outstanding in-plane switching (IPS) 178° wide viewing angle with stunning color consistency. No matter how you tilt or shift your phone, for instance in a racing game, colors stay vibrant and road conditions, visible.

A thinner, better display
Fully laminated Corning® Concore™ glass

The best LCD display has its limits. In order to make the best display possible, we used advanced OGS full lamination technology to integrate layers of protective glass and touch sensor into one. This eliminates light refractions caused by air gaps between each layer, so you enjoy more screen light, richer colors and better contrasts. It also keeps Mi 4i in ultra-thin shape.

A sleeping beauty
Display looks stunning even on standby

A great display should always look beautiful awake or asleep. With OGS full lamination, the display and its borders blend seamlessly together in a uniform, gorgeous, deep shade of black. So Mi 4i looks great in your hand, even on standby.

64-bit performance 2nd gen Qualcomm® Snapdragon™ 615 octa-core processor
Push boundaries with 64-bit performance, which processes twice more data than 32-bit at any one time. The 2nd generation Snapdragon 615 is faster than previous models and has 4 performance cores clocking 1.7GHz and 4 power-saving cores running on a lower 1.1GHz. It is perfect for multitasking and running demanding applications of any kind. Paired with an Adreno 405 GPU and support for OpenGL ES 3.0, the latest standard in 3D gaming, Mi 4i is adept at handling both everyday apps and intense 3D games.

13MP Sony/Samsung camera, f/2.0 Intelligent two-tone flash
Let Mi 4i inspire with the professional sharpness of its 13MP Sony/Samsung camera, artistic f/2.0 background blurring, and innovative technologies that adapt to a range of situations. So that even in low-lighting, the two-tone flash can intelligently assess room color temperature to emulate natural lighting. Selfies look amazing with a 5MP front camera and Beautify, a gorgeous built-in tool that applies one of 36 smart profiles for an all-natural glow.

4G Dual SIM, Dual Standby
The best way to stay truly connected
With 2G/3G/4G support on both dual SIM slots and support for up to 16 bands, there's no stopping when you're with Mi. Manage personal and work calls with ease, with intelligent dual SIM features and detailed preferred network settings for each card

3x faster with 802.11ac Wi-Fi
Stream and download on the latest 802.11ac Wi-Fi wave 2 MU-MIMO that's three times faster than previous Wi-Fi speeds. Dual band 2.4GHz and 5GHz Wi-Fi provides for faster, more stable connections - perfect for watching HD videos or downloading large files!
Bluetooth® 4.1 Low Energy
Faster transfer rates and lower power consumption than Bluetooth® 4.0

Accomplish more with a 3120mAh battery
We've put considerable effort into fitting the highest battery capacity possible to power Mi 4i's stunning 5" display while maintaining a slim profile. This meant using the highest energy density battery technology – 4.4V 700Wh/L lithium-ion polymer cell. To save every inch of space, we then redesigned Mi 4i to include a double-sided circuit board and custom ultra-thin display. The result is an incredibly thin frame that's just 7.8mm, but with an all-day 3120mAh battery with Quick Charge that charges up to 40% in an hour.

Pump up the volume with Smart PA playback
You shouldn't have to put your phone in a glass cup to amplify sound. That's why Mi 4i has Smart PA, which amplifies sound significantly and improves playback quality while protecting speakers from damage at high volume levels. It's a difference your ears will pick up in an instant.
Designed for your hand
Anti-grease coating / 5 color options
Finely textured and matte-sprayed for resistance to fingerprints and grease, the unibody design and matte back cover is smooth to the touch and feels great against skin. The back cover fits just right and bends seamlessly across the sides to meet the front display. Available in white, with colorful versions coming soon.
