Phones MI 4i. Smartphones Xiaomi Mi4, MI4i, MI4C - What is the difference? Information on other important connection technologies supported by the device

Xiaomi MI 4I differs from the older MI model 4 plastic, and not a metal case and a weaker processor ( Qualcomm Snapdragon. 615 against Snapdragon 801). But it has two slots for SIM cards and a thinner case in combination with more tank (!) Battery. In addition, this is the first Xiaomi smartphone on Android 5.0 Lollipop. Already this is a reason to pay attention to him.

Since this is the first review of the Xiaomi smartphone on our portal, let's say a few words about the company. It was founded quite recently, in 2010, and its first product - software: MIUI interface for Android. But by the end of 2014, the company ranked third in the world of smartphones after Samsung and Apple. The price dumping, imitation of Apple (and in almost everything - from solutions in the MIUI interface to the corporate identity of the head of the company La Jusun) and really successful devices - and now about the company from Shenzhen says the whole world. And someone will even prophet that it is she who in the near future will become the chief player in the smartphone market, and Apple and Samsung will swallow dust. At least, growth rates hint.

Serious expansion beyond China Xiaomi began last year with the involvement of the former Google Hugo Barra employee, but it makes it relatively slow. In any case, in Russia, the official sales of Xiaomi gadgets (and in the range of companies there is something to see in except for smartphones - right up to the action cameras and sneakers!), With the exception of tablets, so far have not begun. So we are talking about the "gray" smartphone, without official support for the manufacturer - as often happens with the "Chinese".

Equipment

Packaging Xiaomi Mi 4i from angry cardboard with a minimum amount of inscriptions is made in a traditionally minimalist style. The huge sizes of the box are not due: the contents along with the smartphone itself does not occupy half the volume.

The equipment itself is also ascetic. The kit invested only the Micro-USB connecting cable and the large charge device (2 A output current), nothing more. In such a box, there would be enough space for the mass of additional accessories - now it basically stores air.

Appearance and ease of use

The design of Xiaomi Mi 4i is very different from seemingly related to the company's flagship - MI4. It immediately it becomes clear that we have been simplified with a simplified model, which was tried to give the item-held species: the metal in the outside of the corps is not at all, the brilliant bezel disappeared, the gloss also disappeared, the body is fully made of the matte unquenchable plastic without any additional complicating Design details. The entire housing is a single plastic brown.

And at the same time, as soon as you take a smartphone in your hands, you understand why Xiaomi has so many zealous fans around the world, and even in those countries where this trademark is not presented at all as we have in Russia. Xiaomi does not know how to chelling, and that says it all. Even this inexpensive apparatus with a plastic case after a short acquaintance from the hands of the release no longer wants - this smartphone is so organic in its laconic simplicity.

The metal bezel disappeared, thrown on the look and well-looking at the shelf in the store's store - also, but the more practical matte, a little grungy polycarbonate came to their place, which does not slip out of the hands, and the fingerprints are practically not collecting. It is clear that the material is good and wear-resistant. Most likely, such a material will be preserved a presentable species for a long time - it's simplicable to deteriorate here, and small scratches on the surface of the body are not noticeable at all.

And most importantly, it should be noted: MI 4i is much smaller and easier and easier than its older fellow, and in general is one of the smallest and thin five-year solutions in the market. Due to the case of polycarbonate, the smartphone turned out to be very easy, its mass does not exceed even 130 grams. So, with such a thin and lightweight case, a smartphone with full right can be called an elegant mobile device, comfortably suitable for the hand of any size.

Replaceable caps, like the flagship MI4, here, of course, is not provided, the Xiaomi Mi 4i body is completely monolithic, from which it follows and the corresponding way to install the cards. Both SIM cards are inserted into a single side slot on the sled, the connector supports working with two MICRO-SIM format cards, but there was no place for memory card in Xiaomi Mi 4i.

The rear side of the body accommodates the covering speaker with the lattice, the main chamber and flash. The camera module does not repel out of the housing, and even on the contrary, it is barely recessed into the metal protective ring framing it. The LED flash consists of two multi-colored sections, it can be used as a flashlight.

The speaker in the worst traditions of the past was not displayed in the lower end, but on the back surface of the case, so that the sound and lying on the table, and the smartphone being in the hands of the smartphone is always directed to the opposite side of the user, which is deprived of meaning, but so developers are more convenient to place elements inside the housing . A small protrusion near the lattice slightly lifts it over a solid surface, so that it does not overlap the sound.

Front panel fully covered flat without side protective glass CORNING CONCORE GLASS, in which a small slot is cut to accommodate a spoken lattice. Near the grille there are sensors, a front camera, as well as the LED event indicator, work and even the color of which the user can configure independently in the appropriate section of the menu.

It's nice that, unlike the same Lenovo, Xiaomi does not allow themselves to descend to such petty things as saving on user comfort, therefore, even in such an inexpensive solution, it also has a full backlight of the buttons, and the Event LED already mentioned above. Located under the screen control buttons are also equipped with double functionality: the sensors react differently to a short and long-term touch, and all these features can be completely reconfigured by the user itself.

Mechanical keys are familiar to each other at one face. Large buttons, metallized, discard outside the housing at a sufficient height, easily fasten blindly, have an elastic and distinct move. In general, there are no claims to elements.

On the lower end of the device is placed a Micro-USB connector that supports the connection mode. external devices (USB OTG). Accordingly, only a nest for connecting headphones (3.5 mm per minijack) is placed in the upper end. There are no plugs and covers on the housing, since the device is not equipped with protection against water and dust. Do not find on the housing and attachment for the strap. Wireless charging device also does not support.

As for coloring, then the buyer is where to get roaring: for its model MI 4i in Xiaomi, they prepared as many as five bright colors: from traditional white and black to more frivolous blue, pink and even yellow.

Screen

The Xiaomi MI 4I smartphone is equipped with a SHARP / JDI IPS sensory matrix with OGS technology, combined with a protective glass Corning Concore Glass. Screen dimensions are 62 × 110 mm, diagonal - 5 inches, resolution - 1920 × 1080 points. Accordingly, the density of pixels is high and is 441 ppi, which is more than worthy for a smartphone.

The frame around the screen is not so thin, its width (from the screen to the edge of the case) on the sides is about 3.5 mm, the upper and lower edges - 14 mm.

The brightness of the display can be adjusted manually, and you can use automatic adjustment based on the operation of the lighting sensor. Multitouch technology allows you to handle 10 simultaneous touches. There is a smartphone and an approximation sensor that blocks the screen when making a smartphone to the ear.

Detailed examination with the use of measuring instruments was conducted by the editor of the "Monitors" and "Projectors and TV" sections of Alexey Kudryavtsev. We present his expert opinion on the screen of the sample under study.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface resistant to the appearance of scratches. Judging by the reflection of objects, the anti-glare properties of the screen is not worse than the Google Nexus 7 (2013) screen (hereinafter simply Nexus 7). For clarity, we give a photo on which the white surface is reflected in the screens (left - Nexus 7, on the right - xiaomi mi 4i, then they can be distinguished by size):

The Xiaomi Mi 4i screen is even slightly darker (brightness of photographs 124 against 130 at Nexus 7). Two of the reflected objects in the Xiaomi Mi 4i screen is very weak, this suggests that between the layers of the screen (more specifically between the outer glass and the surface of the LCD matrix) there is no airbap (OGS-One Glass Solution type screen). Due to the smaller number of boundaries (type of glass / air) with highly different refractive ratios, such screens look better in conditions of strong external illumination, but their repair in the event of a cracked exterior glass costs much more expensive, since it accounts for a whole screen. On the outer surface of the screen there is a special oleophobic (tight-repellent) coating (efficient, noticeably better than Nexus 7), so traces from fingers are removed significantly easier, and appear at a lower rate than in the case of conventional glass.

For manual control Brightness and when displaying a white field, the maximum brightness value was about 390 kD / m², minimum - 6 cd / m². The maximum brightness is not very high, but, given the excellent anti-reflective properties, readability even on a sunny day outside the room will be at a high level. In complete dark, brightness can be reduced to a comfortable value. In stock Automatic brightness adjustment over the illumination sensor (it is located to the left of the slot of the front loudspeaker). In automatic mode, when changing external light conditions, the screen brightness is rising, and decreases. The operation of this function depends on the position of the brightness adjustment slider. If it is 100%, then in complete darkness, the automatic brightness adjustment function reduces the brightness of up to 100 cd / m² (excessively bright), in conditions of an artificial light of the office (about 400 lux), the brightness increases to 290 kD / m² (multipato), in very Bright environment (corresponds to the lighting clear outside of the room, but without direct sunlight - 20,000 LCs or a little more) is installed at 390 kD / m² (as needed). The brightness slider is 50% - the values \u200b\u200bare as follows: 7.5, 170 and 390 kD / m² (acceptable values), by 0% - 6, 30 and 390 kD / m² (logic traced). That is, the auto-adjustment feature of the brightness works absolutely adequately. At any level of brightness, the backlight modulation is practically absent, so there is no screen flicker.

This smartphone uses an IPS type matrix. Micrographs demonstrate a typical structure of subpixels for IPS:

For comparison, you can familiarize yourself with the micrographic gallery of the screens used in mobile technology.

The screen has good viewing angles without a significant shift of colors, even with large looks from the perpendicular to the screen and without inverting shades. For comparison, we give the photos on which the same images are displayed on Xiaomi Mi 4i and Nexus 7 screens, while the brightness of the screens is initially installed by about 200 kD / m² (on a white field in full screen), and the color balance on the camera is forcibly switched to 6500 to the camera. . Perpendictively to the screens White field:

Note good uniformity of brightness and color tone of the white field. And test picture:

The colors on the Xiaomi Mi 4i screen are oversaturated, the color balance varies slightly. Now at an angle of about 45 degrees to the plane and to the side of the screen:

It can be seen that the colors did not change much from both screens, but Xiaomi MI 4i contrast decreased to a greater extent due to the strong decrease of black. And white field:

The brightness at an angle at the screens has decreased (at least 3 times, based on the difference in excerpt). However, the Xiaomi Mi 4I screen at this angle is noticeably lighter. The black field during the deviation on the diagonal is highlighted, and acquires a red-purple or yellowish tint. Photos below are shown (the brightness of white areas in the perpendicular plane of the directions of the direction is approximately the same!):

And at a different angle:

With perpendicular view, the uniform of the black field is excellent:

Contrast (approximately in the center of the screen) is not very high - about 680: 1. Response time when switching black-white-black is 16 ms (9 ms incl. + 7 ms Off). The transition between the halftons of gray 25% and 75% (for the numerical value of color) and back in sum occupies 24 ms. Built according to 32 points with an equal interval in the numerical value of the shade of a gray gamma curve revealed a small collar in the shadows. The index of the approximating power function is 2.15, which is slightly lower than the standard value of 2.2. In this case, the real gamma curve is noticeably deviated from the power dependence:

In this device, you can change the color balance, choosing two saturation profiles and one of the three color temperature profiles:

Variation of a saturation profile does not lead to noticeable changes in the image, the color coverage is still noticeable wider than SRGB:

We look at the spectra:

They are atypical, but we have already seen them in the case of Sony Xperia Z2 and several other devices, for example, Xiaomi Mi Note. Sony points out that these screens use LEDs with a blue emitter and green and red phosphor (usually a blue emitter and yellow phosphor), which in combination with special matrix light filters and allows you to get a wide color coverage. Most likely, this statement is true for Xiaomi Mi 4i. The characteristics of this smartphone simply write that coverage is very wide and amounts to 95% of NTSC coverage and that colors are 32% brighter (32% more vivid) than the iPhone 6, presenting this fact as indisputable dignity. This is the fruit of the sick imagination of the Marketologists of Xiaomi, who need to lure the average man. Of course, every wonderful and without violations of the color perception, looking at this screen on a photo of something familiar, it is better for a photo of the face, will understand what is really happening, as in the end the colors of images - drawings, photos and films - oriented on SRGB space (and such an overwhelming majority), have unnatural saturation. This is especially noticeable on recognizable shades, for example on skin shades. The example is given on the comparative photo above.

Balance of shades in the case of a default profile (and it is called Natural) On the scale of the gray acceptable, since the color temperature is not much higher than the standard 6500 K, and the deviation from the spectrum of absolutely black body (ΔE) is below 10, which is considered an acceptable indicator for the consumer device. In this case, the color temperature and Δe change little from the shade to the shade - this has a positive effect on the visual assessment of the color balance. (The darkest areas of the gray scale can not be considered, since there the balance of colors does not matter, and the measurement error of the color characteristics on the low brightness is large.)

Select profile Warm Slightly improves the color balance, since the color temperature becomes closer to the standard 6500 K, and Δe on average becomes lower.

Let's summarize. The screen has a sufficiently high maximum brightness and has excellent anti-reflective properties, so the device without problems can be used outdoors even summer sunny day. In complete darkness, brightness can be reduced to a comfortable level. It is permissible to use the mode with an automatic adjustment of the brightness that works adequately. The advantages of the screen should include a very efficient oleophobic coating, no flickering and air gap in the layers of the screen, excellent uniform of the black field, as well as an acceptable color balance. To significant disadvantages - the low stability of black to the rejection of the view from the perpendicular to the plane of the screen and unnecessarily wide color coverage that is impossible to adjust to SRGB. However, taking into account the importance of the characteristics for this class of devices, the screen quality can be considered high.

Sound

Sounds Xiaomi Mi 4i for its level is not bad. The main speaker makes moderately loud sound, clean at all levels of volume, but without noticeable availability. low frequencies. In the headphones, the situation is much better: sound and loud, and juicy, and bass enough. Non-smartphone not invested, but in the settings you can choose specialized profiles with pre-installed values \u200b\u200bspecifically designed for specific models Headphones. Also in the company's branded music player, the user has available manual sound quality control settings in the form of pre-installed equalizer values. In the conversational dynamics, the question of the interlocutor, the timbre and intonation remain recognizable.

FM radio with the ability to record programs in the smartphone is available, it works only with connected headphones. Telephone conversations A device can be recorded by regular means, sufficiently press the corresponding button right in the telephone application interface.

Camera

Xiaomi MI 4i is equipped with two modules of digital cameras with a resolution of 16 and 5 megapions. For the front chamber, a 5-megapixel module with lens with a diaphragm F / 1.8 without autofocus and its own flash is used. Among the settings, there is the possibility of using a portrait improvement regime, in which the procedures are used to lighten the skin, whitening the teeth, dimming, decrease in cheekbones for Asian smartphones. Such programs even learned to determine the gender and age of a person, automatically adding a profile with a pre-prepared set of improvements to its type of face. And yet, the very quality of shooting on the frontal camera Xiaomi. Mi 4i leaves much to be desired.

The main chamber uses a 13-megapixel module with a lens with five lenses with a diaphragm F / 2.0, the next fast autofocus and a double multi-colored LED flash. Only a streamlined formulation of developers hints on the authorship of the module: "Sony / Samsung Camera".

The camera control menu uses its own, which is not surprising, because the smartphone is running the MIUI user interface. Multiple settings, the menu is detailed, but you need to get used to it. For example, it is impossible to directly set the resolution of the picture, you can only choose between the veiled definitions of the type "high or low quality" or "normal or widescreen aspect ratio". In manual mode, it is possible to affect the balance of white, exposure, the ISO level, there is also several additional modes, such as panoramic, night, decoration, and even the mode of changing the focus on the already received photo is all familiar and familiar.

The camera can shoot video with a resolution up to 1080p, as well as conduct an accelerated and slow survey. The example of the roller is presented below.

• Roller №1 (35 MB, 1920 × 1080, 30 FPS)

	Text worked well.
	The foliage merges almost immediately.
	With macro shot with insufficient lighting, the camera copes.
	Good sharpness over the field and by plans.
	The sharpness on distant plans is almost excellent.
	The numbers of the nearest cars are distinguishable.
	Good sharpness over the field and by plans, but drops a little in the corners.
	Macro movement manages well.

We also tested the camera on the laboratory stand on our technique.

The camera really succeeded. Despite the fact that there are failures, in general, it works very well. In addition, the most successful pictures in the series are also sharpness, and working out the details, and work with noise on them is very good. For a completely standard 13 megapixel module, the result is really good. The laboratory test confirms the observations made. As is visible from the graph, they suffer with a deterioration of lighting mainly angles, in the center the same result always remains at a fairly high level.

The camera copes well with documentary and with artistic shooting.

Telephone part and communication

The smartphone works standard in modern 2G GSM and 3G WCDMA networks, as well as support for the fourth-generation network LTE Cat4 (FDD-LTE: 1800/2600 MHz), that is, the frequencies used in Russia are also supported. In practice with the SIM-card of domestic operators MTS and Beeline, the smartphone is registered and operates in LTE networks. Rest network features Smartphone is also quite satisfactory: there is support for Bluetooth 4.1, both Wi-Fi ranges are supported (2.4 and 5 GHz), Wi-Fi Direct, Wireless Display. (WIDI), you can organize a wireless access point via Wi-Fi or Bluetooth channels. Micro USB 2.0 connector supports the connection of external devices (USB Host, USB OTG), so you can connect to the Micro-USB port of flash drives and mouses with keyboards. But support for NFC technology Chinese here, as usual, not implemented.

The navigation module works with GPS / A-GPS, supported domestic system GLONASS and Chinese Beidou. The operation of the navigation module of special complaints does not cause, the speed of detection of satellites at a cold start is less than a minute. Sensor implemented among smartphone sensors magnetic fieldOn the basis of which the electronic compass of navigation cartographic programs is usually functions.

The phone application supports Smart Dial, that is, during a set telephone number Immediately, the search for contacts is immediately implemented, in the settings there is a non-free method of entering the type swype. During a telephone conversation in the menu, you can click the recording button to save the conversation, voices are recorded on both sides. For convenience of managing one hand, it is possible to change in the size of the entire working area of \u200b\u200bthe screen. The settings have the ability to independently select the size of the reduced screen.

The smartphone supports working with two SIM cards. All work with them in the menu is comfortable organized on one page, all settings are conveniently converted, the menu is presented visually and intuitively understandable. You can assign basic for voice calls or data transmission any of the SIM cards. With 3G / 4G networks, the SIM card can operate in any slot, but at the same time in this mode only one of the cards can function. To change the settings of the slots of the card, you do not need to change places - it can be done directly from the phone menu. Working with two SIM cards is organized by the familiar DUAL standard SIM Dual. Standby, when both maps can be in active standby mode, but simultaneously work cannot be - a radio module here is only one.

OS and Software

As a system in the device, the Google Android fifth version (5.0.2 lollipop) software is used, but it is practically not recognized here, because on top of the Google interface the shell is installed under the name MIUI 6. This alternative interface is well-known not only for the multi-millionth army of fans itself Xiaomi brands, but also users of smartphones of other firms, since this shell acquired such high popularity that is used everywhere and other chinese manufacturers, and even private users for customization of mobile devices of various brands.

The shell looks neat, concisely, all settings are conveniently distributed over their sections, everything is combed and ordered. Separate menu installed programsNaturally, no, the icons of installed applications are immediately laid out on desktops, it is possible to create folders and widgets. It is possible to reduce the working area of \u200b\u200bthe screen for ease of control of one hand. At the same time, there is no such wide variety of support for working with gestures, as in the same Flyme OS, the shell will have to do with lovers of practical minimalism. Preset programs Not so much, but they are not too interesting to users outside of China, but the set of utilitarian applications may be quite useful with us. In order to use part of the programs, you will have to start your own account in Xiaomi Mi services.

Performance

The Xiaomi Mi 4i hardware platform is based on a familiar eight-casual single-cylinder system (SOC) Qualcomm Snapdragon 615 (MSM8939). This 64-bit platform is made using Big.Little technology, where four Cortex-A53 processor kernels are adjacent to the four of the same Cortex-A53 kernels, but these "fours" differ the maximum frequency of work. In the usual case, depending on the nature and degree of loading, either 4 "younger" (up to 1 GHz) are included, or 4 "senior" (up to 1.5 GHz) nucleus, which allows energy. Only in the case of Xiaomi Mi 4i is used SOC SOC SNAPDRAGON 615 of the second generation with an increased maximum speed of the cores to 1.65 GHz, that is, the platform here is a bit more powerful than its "ordinary" analogues used in other similar solutions. For the processing of graphics here is all the same ADRENO 405 video screen with a frequency of up to 550 MHz. SOC SNAPDRAGON 615 is made according to the process of 28 nm, and belongs to the mid-level category.

The amount of operational memory of the smartphone is 2 GB. The device has 16 GB flash memory installed, from which about 11.4 GB is available for the needs of the user itself. The amount of memory can not be increased due to mICROSD cardsBut it is supported by connecting external devices to the MICRO-USB port (OTG).

I must say that the Snapdragon 615 platform is now a true middle pepper mobile SOC.because it gives precisely the average result in terms of performance, no higher. For example: His configuration and competing MediaTek MT6752 competing with it in the complex benchmark Antutu more than 40K points, and in all other tests, it also has results higher. But it is also worth noting that in the case of SOC SOC SNAPDRAGON 615 of the second generation with an increased maximum core frequency, rose, respectively, the performance of the system as a whole. This is especially good on the example of the integrated antutu and geekbench 3 tests, as well as specialized browser tests. In Antutu, its result reached more than 35k, and in the 64-bit version of the test and got to 38K, which in the usual modification of Snapdragon 615 never showed.

At the same time, the same ADRENO 405 video subsystem used in all cases with the same frequency (550 MHz), in graphics tests, accordingly, did not demonstrate any increase. And in general, in general, even in such an overclocuted modification of SOC Qualcomm Snapdragon 615 in all tests, both complex and specialized, it still turns out to be less productive than its direct competitor, MediaTek MT6752.

There is nothing to add here, the platform is far from its capabilities from the most productive modern platforms that are installed in flagship decisions. The drift of devices with such a filling is a confident medium level, no more. However, the smartphone described today is quite productive enough for its capabilities for some time for some time to perform the main tasks.

Testing in the latest versions of Antutu and Geekbench 3 complex tests:

All the results obtained by us when testing the smartphone in the most recent versions of popular benchmarks, we are conveniently reduced to the table. The table usually adds several other devices from various segments, also tested on similar recent versions of benchmarks (this is done only for a visual assessment of the resulting dry numbers). Unfortunately, within the same comparison, it is impossible to submit results from different versions Benchmarks, therefore, many decent and actual models remain "behind the scenes" - due to the fact that they at one time passed the "obstacle course" on previous versions of test programs.

Testing a graphic subsystem in 3DMark game tests, GFXBENCHMARK, and Bonsai Benchmark:

When testing in 3DMark for the most productive smartphones now it is possible to run the application in Unlimited mode, where the resolution of the rendering is fixed to 720p and is turned off by VSYNC (due to which the speed can rise above 60 FPS).

Browser cross-platform tests:

As for the benchmarks to estimate the speed of the JavaScript engine, it is necessary to always make a discount on the fact that they are significantly dependent on the browser in them, in which the comparison can be truly correct only on the same OS and browsers, and such an opportunity is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

Heatons

The back surface is shown below (the top in the picture is on the right), obtained after 10 minutes of the battery test operation in the GFXBenchMark program:

It can be seen that the heating is localized in the upper part of the device, which, apparently, corresponds to the location of the SOC chip. According to the heat frame, the maximum heating was 40 degrees, it is relatively few.

Video playback

To test "omnivities" when playing video (including support for various codecs, containers and special capabilities, such as subtitles), we used the most common formats that constitute the bulk of the content available on the content network. Note that for mobile devices it is important to have the support of hardware decoding of videos at the chip level, since to process modern options due to the processor nuclei are most often impossible. Also, it is not necessary to wait from the mobile device of decoding everything, since the leadership in flexibility belongs to PC, and no one is going to challenge it. All results are reduced to a single table.

According to test results, the subject turned out to be equipped with all the necessary decoders, which are necessary for full playing of most of the most common multimedia files. That is, for successful playing them, it is not even necessary to resort to the help of a third-party player - for example, MX Player, although in it the playback will also be carried out with support for AC3 sound format, which cannot but rejoice.

Testing the features of the video output spent Alexey Kudryavtsev.

The MHL interface, like the Mobility Displayport, we did not find it in this smartphone, so I had to restrict ourselves to testing the image of the video files to the screen itself. To do this, we used a set of test files with one division by the frame with an arrow and a rectangle (see "Methods for testing the playback devices and displaying the video signal. Version 1 (for mobile devices)"). Screen shots with shutter speed in 1 C helped to determine the nature of the output of video files with various parameters: resolution ranged (1280 to 720 (720p) and 1920 per 1080 (1080p) pixels) and frame rate (24, 25, 30, 50 and 60 frame / from). In tests, we used the MX Player video player in the "hardware" mode. Test results are reduced to the table:

720 / 30p. excellent not 720/25p. oK not 720/24p. excellent not

Note: If in both columns Uniformity and Pass Green estimates are exhibited, it means that, most likely, when viewing the films of artifacts caused by uneven alternation and passage of frames, or will not be seen at all, or their number and notice will not affect the preservation of viewing. Red marks indicate possible problems associated with playing relevant files.

According to the frame output criterion, the quality of video files on the screen of the smartphone itself is good, since frames (or frames of frames) can (but not obliged) to be output with more or less uniform intervals and in most cases without frames of frames. When playing video files with a resolution of 1920 to 1080 pixels (1080p), the image of the video file is output one-in-one, accurately along the screen border and in the true permit full HD. The brightness range displayed on the screen corresponds to the standard range of 16-235. However, in the shadows of the order of 4-5 closest to black shades are indistinguishable from it in brightness, but at least in the lights are displayed all gradations of shades.

Battery life

Xiaomi MI 4i has a fixed battery worthy for modern tank smartphones at 3120 mAh. However, surprisingly, the smartphone demonstrated a rather modest battery life in all typical operating modes (reading electronic books, watching movies, games).

According to the subjective sensations, without recharging in the normal daily operation, the device confidently lives to the night charging, this is the main thing. The developers themselves argue that the smartphone is capable of functioning 35 hours in conversation mode (3G) and 11 hours in the HD video view mode, but the second approval was clearly embellished.

It is also worth noting that our testing was carried out without using energy-saving functions, in a productive mode of operation.

Uninterrupted reading in the FBReader program (with a standard, bright theme) with a minimum comfortable level of brightness (the brightness was set per 100 cd / m²) lasted until the battery lasts a little more than 11 hours, and with unlimited viewing video in high quality (720p) with the same level of brightness through home wi-Fi network The device lasted no more than 8 hours. The device supports fast charging, per hour the battery is charged to 40%. The total charge time from the standard (non-complept) charger (output current 5 to 2 A) is also quite small and is about 2 hours 20 minutes.

Outcome

As for the cost of the device, while, as before, Xiaomi smartphones are officially not represented on the Russian market, therefore, to acquire MI 4i, you will have to use one of the offers of electronic stores with delivery from abroad. Initially, the cost of the device was declared only at $ 205, but in reality in online stores it is difficult to find this model at a price below $ 230-240, and russian stores Offer this unit at a price of 15 thousand rubles. It is curious that during the moment in nature there was only one modification of the smartphone, with 16 GB of internal memory, but soon the model will be released with an increased up to 32 GB volume, however, it will cost, respectively, a little more expensive. The device for its level is quite good: he has a high-quality bright screen with flagship resolution, nonsense in appearance, but a kindly tailored ergonomic thin and lightweight case with a worthy sound of speakers, a good basic camera, a satisfactory set of network modules. The duration of autonomous work does not affect the imagination, but it is not failed. In general, we are truly mean average in all respects the solution is not very cheap, but at the same time very high-quality for your level.

What did not like

Of the minuses, the battery is weak, the first week was very fast. Now it seems to be enough for a day for a day. But what to do for everything you need to pay - for the thickness, screen, wifi, 4G, processor, etc. We pay a battery. Still of the minuses are 16 gigs, but it is apparently ahead while it is enough, and with the 8th it is easily synchronized as a flash drive - it will not be cleaned of labor. With active use heats up the top of the chamber but tolerant. A little more dying speaker, I got used to somehow pogromic.
