Use the Mi 4S smartphone with fast phase-detection technologies and the camera will quickly focus on the desired scenery. The image quality will be much better after pressing the shutter button. A high-performance image processing technology and improved dark shades make your image more contrast.

  • 13 megapixel high definition sensor
  • Auto-phasing ultra-fast focusing technology


The focus technology originates from the single-lens reflex cameras. Focus method is similar to the human eye. Camera focuses on less than in a second. With a quick capture you will not miss a single unique moment.

The dynamic range adjusting

The dynamic range is being optimized in real time according to the light and shade of each pixel. Functions of very bright areas darkening and dark areas lightening are optimized automatically. So you will get each photo in a high quality.

Pure night landscapes

Usually there are many WiFi users in a café or other public place, so the speed of the network can become very weak. It slows the transmission speed when multiple devices are connected to the router. Mi 4S supports the mass mailing mode, so when you connect your smartphone to the router with a MU-MIMO technology, your Internet speed will not slow down, even if there are a lot of other users.

3260mAh battery

Thinner design, longer period of continuous use

The smartphone is equipped with a battery of 3260mAh capacity. We have achieved this thanks to the energy of high-density technology and optimization of the design. Thus, the battery thickness is 7.8mm only. It works for a long time and is very pleasant to the touch. It also has a Quick Charge 2.0 technology. So, it won’t take a long time to charge the battery.

Use the smartphone as a remote control

The smartphone is equipped with an infrared module. Use it as a remote control for the TV, air conditioner, single-lens reflex camera, and other 10 electrical appliances with remote control by more than 2 000 technology brands. You can view a TV program and set a reminder.

USB Type-C connectors with bilateral (two-sided) connection to the port for recharging

USB Type-C has bilateral symmetrical connectors which can be used for device connecting to the computer. The support for OTG protocol and the ability to connect a USB keyboard or a USB drive are very convenient for the game.

Slim, elegant 5-inch smartphone

Xiaomi Mi 4S has a metal frame and a two-sided glass coating, while it weighs 133g only. Smooth bright corners of the smartphone body, 3D arc lines contribute a convenient position in your hand. The next breakthrough is the elegant 5-inch smartphone with a powerful high-capacity battery.

The phone is easily operated with one hand, while it improves properties and a high capacity battery.

The smartphone is equipped with all the advanced technologies, while its weight is 133g only. Smooth bright corners and 3D arc lines contribute a convenient position in your hand. Exquisite and sparkling, two-sided glass coating makes it very smooth and pleasant to the touch.

133g, lightness and comfort

Softness is the first impression of the Mi 4S

A metal frame, a two-sided glass coating, even a high capacity battery are possible for the smartphone with weight of 133g only. We chose a light and high-quality, reliable and outstanding magnaly (aluminum-magnesium alloy). This material has a small weight. Also it is a good protective cover for your phone. It gives a more rational layout to the irregularly shaped battery.

  • Weight — 133g
  • Thickness — 7.8mm

High energy density

High capacity battery 3260mAh

The energy density is up to 677Wh / L. The battery has a large amount of electricity, using the advanced technology of high-voltage 4.4V. Thanks to the battery capacity of 3260mAh you can enjoy the continuous usage of your smartphone.

3D arc metal frame

We hope that the 3D arc metal frame will give special tactile sensations to Mi 4S and make it stylish and fashionable. Accurate and high precision CNC processing with magnaly, polishing, anodizing and 10 other different technologies were used to create a beautiful 3D arc metal frame. Radiance from every corner of the smartphone will attract your eye immediately.

Smooth and rounded smartphone’s frame contributes a convenient location in your hand. For the outer surface of the frame polishing technology we used zirconium sand under the number 205 and the structure became soft and pleasant to the touch.

Bilateral glass coating: smooth, translucent and stylish

For the front and rear sides of Mi 4S we have chosen glass for main camera of smartphone. The glass coating is very pleasant to the touch. And it looks very stylish. We also used an ion technology to transform and improve the strength and endurance of the glass coating.

Lightweight and durable aluminum-magnesium frame

The smartphone frame is made of aluminum-magnesium alloy and it also has passed stringent safety tests. In case when your phone falls or other unforeseen situations the frame will protect the integrity of the major internal components. Despite the fact that magnaly mass is very small, it safes all the major components.

Special texture

Special color

Mi 4S is made in 4 basic colors: classic black, white, gold and purple — special color for girls. The front and rear sides of the smartphone have the same color.

On the back side of the smartphone all colors are subtle and have delicate cross-shaped lines, which sparkle bright and shimmer under the sunlight. The purple smartphone presents an effect of nacre, which girls will like.

The tireless work on every detail to make them even more beautiful

As soon as you take the Mi 4S, you will immediately notice the subtlety of performances: the whole smartphone body merged with its camera gives a pleasant tactile sensation when you touch the metal buttons. Also it has a neat USB Type-C connector. All the little things are created with great effort and love.
