Positioning

Lenovo's main partner has been Intel for many years, it is on the processors of this company that laptops and desktop computers, which means that cooperation is maximum and both companies have strategic interests in each other. It has long been known that Intel was late to the mobile solutions market, none of the major companies are trying to produce devices on Intel Atom, which forces Intel to pay for their production. But even paying for development, design costs, actually subsidizing its own sales and incurring multi-billion dollar losses, Intel cannot ensure that a noticeable number of models appear on the market. This is not happening, and consumer attitudes towards Intel Atom remain not just cool, but scalding cold. The only option is to sell such solutions as cheaply as possible so that they outperform competitors in price. In Russia, one can recall the K-series, which professed just such an approach. The party was very small, a kind of trial balloon.

For Lenovo release Smartphones based on Intel Atom are the support of a strategic partner, there are no other reasons for the appearance of such smartphones and tablets. From the point of view of consumers, these devices have a number of disadvantages, and even against the background of analogues from Lenovo. For example, a very interesting device can be distinguished in the P series - Lenovo P70.

There is no way to avoid comparing the Lenovo P70 and P90, since at first glance they are very similar devices, differing only in screen size - in junior model diagonal 5 inches, in the older one - 5.5 inches. But as soon as you start to dig into the details, you understand that the external similarity does not give an idea about these devices. So, the P70 has fast charging, but the P90 does not have it, although the battery is of the same capacity. The first one works on a single charge for a couple of days with a noticeable load, the second - the same time with a very moderate one. On the first one, all applications and games are launched, on the second, they sometimes crash. The list can be continued indefinitely, in the review I will mention the main points and differences. I will only note that the P90 example shows well how much depends on the chipset, the perception of the device changes dramatically.

The resulting smartphone is interesting in terms of cost, if you are willing to put up with a number of shortcomings. It is also quite suitable for Intel employees, for everyone else it is of academic interest. Let's see together what features the Lenovo P90 has.

Design, dimensions, controls

The body is made of polycarbonate, pleasant to the touch, three colors - white, black and red. In all variants, the front panel is black.

The quality of the plastic is good, there are no traces of the hands. The case is made non-separable, unlike the P70. On the right side there is only a slot for a microSIM card, it is installed in the tray.

Let me remind you that the P70 supports two SIM-cards, there is a slot for memory cards. It is strange that the flagship of the line of these options did not receive. But this is a limitation of Intel Atom.

On the left side there is a paired volume rocker and an on/off button. At the top end there is a 3.5 mm jack, at the bottom there is a microUSB connector. The rear panel houses an LED flash, as well as a 13-megapixel camera lens. There is only one speaker, it can be seen on the back cover.

The dimensions of the phone are 150x77.4x8.5 mm, the weight is 156 grams. It's big enough for a 5.5-inch screen, but given the large battery, that could theoretically be forgiven.

Display

The screen is 5.5 inches, has a FullHD resolution of 1920x1080 pixels (400 dpi), IPS. Unlike the P70, it doesn't have any margin of brightness, even at maximum it looks dimmer. Viewing angles also leave much to be desired, look at the photos.

Compared to Lenovo P70 (left) and Samsung Galaxy Note 4 (right):

Adjusting the brightness doesn't help. automatic mode the screen remains dim. Thanks to proprietary settings from Intel, you can set the increased readability of the screen on the street, choose a color temperature.

But here's the problem, none of these settings work, we can say that they are there for show. The colors on the screen change, but you will not see cardinal differences. It's a shame that the screen loses to most IPS matrices, which can be found in similar products.

To explain why the screen brightness is underestimated, it can be explained by the fact that Intel Atom is very voracious and eats up the battery at an amazing rate.

Battery

Battery Li-Pol, it is non-removable, with a capacity of 4000 mAh. Unlike the P70, it does not support fast charging technology, which is a shame. The full battery charging time is not 2 hours, but about 3.5 hours. It's even funnier that the Intel Atom doesn't have support for Quick Charge chargers. In theory, any phone without this technology will use charging in normal mode, the charge current will automatically decrease. For the first time in the P90, I encountered the fact that charging is shown, but the charge itself does not go. When you try to turn on the phone, it just turns off, his brains go overboard. Checked on chargers from three different companies, none of them work with the P90 - that is, you should always carefully watch what kind of charge you take with you on the road.

Now let's look at real time work in different modes. In my use case, the screen was automatically backlit, I made calls for a total duration of 30 minutes a day, and also spent about 2-2.5 hours in in social networks, the Internet, both via a 3G / 4G connection (mainly) and via Wi-Fi. The phone worked for about 12-13 hours (in P70 the same load gave two full days!). With a smaller amount of use of the device, for example, up to an hour of screen per day, it will last two full days. For such a battery, this is nothing, the power consumption is too high, although the previous Intel generation Atom, on the other hand, was famous for its uptime, now it has spoiled what little that was good.

What can I say, those who fall for paper specifications and think that 4000 mAh batteries are enough for their eyes will be greatly mistaken.

Platform, memory, performance

The model is based on the Intel Atom Z3560 chipset, 4 cores up to 1.86 GHz per core, 64 bit, Intel® Power VR Series 6 graphics coprocessor.

Unlike previous Intel Atom processors, this one is made according to the 22 nm technology standard. The description says a lot about energy-saving technologies, in practice the device works a little, and the chipset is to blame for this. It's a pity, but it's a fact.

The amount of RAM - 2 GB, built-in - 32 GB, available to the user 26 GB. A 4/64GB version will be released later in China.

Now let's focus on performance. Judging by the interface, everything is very good here, no brakes, everything is smooth and pleasant. In synthetic tests, the device shows average results, they are not very high. But that's what these tests exist for, to show virtual parrots. I am sure that for the vast majority of people, the performance of this solution will be enough. The downside is that very often some applications slow down when loading, they can crash for no apparent reason. For example, my maps from Google flew out like that when I tried to launch them from the browser, after rebooting the device for a while the problem disappeared, then it repeated itself.

Communication options

The smartphone works in GSM, HSDPA and LTE (4G) networks, LTE FDD is supported (bands 1, 3, 7, 20), so in Russia the device works without problems with 4G networks. Support for TDD is also announced.

USB. For synchronization with a PC and data transfer, the included microUSB cable is used. USB interface 2.0. USB-OTG standard is not supported.

Bluetooth. Built-in Bluetooth 4.1 module with A2DP profile support.

WiFi (802.11 a/b/g/n/ac). The smartphone has a dual-band Wi-Fi module, it works flawlessly. Like any other modern Android device, Lenovo P90 supports the "sharing" function mobile internet via Wi-Fi (Wi-Fi router).

Camera

The usual 13-megapixel autofocus module with optical stabilization, which gives disappointing pictures, they don't look good even on the phone's screen. However, you can verify this for yourself.

Mobile networks

A mobile network is a radio system that allows multiple mobile devices to communicate with each other.

GSM GSM (Global System for Mobile Communications) is designed to replace the analogue mobile network (1G). For this reason, GSM is often referred to as a 2G mobile network. It is enhanced by the addition of GPRS (General Packet Radio Services) and later EDGE (Enhanced Data rates for GSM Evolution) technologies.	GSM 850 MHz GSM 900 MHz GSM 1800 MHz GSM 1900 MHz
UMTS UMTS is short for Universal Mobile Telecommunications System. It is based on the GSM standard and belongs to 3G mobile networks. Developed by 3GPP and its biggest advantage is to provide more speed and spectral efficiency with W-CDMA technology.	UMTS 800 MHz UMTS 850 MHz UMTS 1900 MHz UMTS 2100 MHz
LTE LTE (Long Term Evolution) is defined as a technology fourth generation(4G). It is developed by 3GPP based on GSM/EDGE and UMTS/HSPA to increase the capacity and speed of wireless mobile networks. The subsequent development of technologies is called LTE Advanced.	LTE 800 MHz LTE 1800 MHz LTE 2100 MHz LTE 2600 MHz

L1 (level 1) cache is small and much faster than system memory, and other cache levels. If the processor does not find the requested data in L1, it continues to look for them in the L2 cache. With some processors, this search is performed simultaneously in L1 and L2.	24 kB + 32 kB (kilobytes)
Second level cache (L2) L2 (level 2) cache is slower than L1, but in return it has a larger capacity, allowing more data to be cached. It, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to look for it in the L3 cache (if available) or RAM.	2048 KB (kilobytes) 2 MB (megabytes)

Front-camera

Smartphones have one or more front cameras of various designs - a pop-up camera, a PTZ camera, a cutout or hole in the display, a camera under the display.

Svetlosila Luminosity (also known as f-stop, aperture, or f-number) is a measure of the size of a lens aperture that determines the amount of light that enters the sensor. The lower the f-number, the larger the aperture and the more light reaches the sensor. Usually, the number f is indicated, which corresponds to the maximum possible aperture of the aperture.	f/2.6
Focal length Focal length indicates the distance in millimeters from the sensor to the optical center of the lens. The equivalent focal length (35mm) is the focal length of a mobile device camera that is equal to the focal length of a 35mm full-frame sensor that would achieve the same angle of view. It is calculated by multiplying the actual focal length of the mobile device's camera by the crop factor of its sensor. The crop factor can be defined as the ratio between the 35mm diagonals of a full-frame sensor and a mobile device sensor.	2.8 mm (millimeters)
Image resolution One of the main characteristics of cameras is resolution. It represents the number of horizontal and vertical pixels in an image. For convenience, smartphone manufacturers often list resolution in megapixels, giving an approximate number of pixels in millions.	2560 x 1920 pixels 4.92 MP (megapixels)

Mid-range model on 64-bit Intel Atom platform

At the very beginning of summer, Lenovo announced the entry into the Russian market of its next smartphone based on Intel processor Atom called Lenovo P90. Thus, this model has become a kind of successor to the work begun by the legendary K900 model, after which Lenovo did not release any more smartphones on Intel platforms. And so the Chinese decided to release a model based on Intel Atom again, and here, unlike the same K900, a 64-bit quad-core chip is already used.

However, it's still not worth equating these two models: the K900 was once a really top-end solution, outperforming many flagship smartphones of that time in terms of performance. Now everything is different: Lenovo P90 is a mid-range solution, both in terms of characteristics and price positioning, and it cannot compete with modern flagships. Nevertheless, the device is quite interesting for its level, especially since you still rarely see a device on the Intel x86 platform in the oversaturated mobile market.

Appearance and usability

In terms of design, Lenovo P90 has nothing in common with the memorable model K900, which is remembered by users not only for the presence of the Intel platform, but also for its solid metal case, which invariably arouses respect and confidence in the greater reliability and durability of such a device. Like it or not, in any case, the P90 is not made of metal, its body is made of plain matte plastic (polycarbonate).

Thanks to this material, the smartphone turned out to be completely nondescript and unpretentious in appearance, there is no design as such, as there are no additional decorating details, such as a metal rim on the side faces. The entire body is completely made of polycarbonate, representing a kind of solid plastic trough with gluing only at the point of contact with the front glass. To be honest, even polycarbonate could have been made something more interesting, an example of this is the unforgettable Nokia Lumia 800 and related models - their design made full use of the features of this material.

However, in terms of practicality, there are no complaints about polycarbonate. Not only are fingerprints not visible on it, but the material itself has a single structure. That is, no matter how deep the scratch on the case is, it will have a uniform color over the entire depth, which allows a smartphone made of such material to stay longer in presentable. In addition, the Lenovo P90 surfaces have a slightly rubberized effect, so the smartphone does not slip out of your hands, it is held securely.

As for the dimensions, the Lenovo P90 is a large mobile device with a screen diagonal of 5.5 inches, so there is no need to talk about the comfort of holding it in your hand. The smartphone is very large, although the mass at the same time is quite satisfactory - just a little over 150 g.

The method of installing a SIM card corresponds to the non-separable monoblock structure of the case: the card enters the side slot on a slide, and is removed by pressing a paperclip key into the hole with a hidden button. However, the hole is so narrow that an ordinary paper clip probably won't fit in there. It is curious that the developers in the case of the P90 decided to abandon the second SIM-card, and even the memory card - there is only one slot. The SIM card is used in Micro-SIM format, not Nano-SIM, which looks a little archaic for the current state of affairs in the market, where Nano-SIM has already replaced its predecessors in almost all top-end smartphones from leading manufacturers.

The front panel of the smartphone is completely covered with a flat protective glass without sides. In its upper part there is a cutout for the speaker grill, right next to it you can see sensors, a front camera peephole and an LED event indicator. The round dot of the indicator is highlighted, reporting the status of charging, as well as incoming calls and messages, there is a separate sub-item in the menu to configure the operation of this element.

About backlighting touch buttons below the screen, the creators in this case took care. The sensor icons are softly illuminated with a not too bright pleasant whitish light, the backlight mode, again, is widely adjustable in the settings.

By tapping on the glass, the smartphone does not wake up here, but there is an alternative in the settings: the ability to activate using the sound buttons. Given the fact that both buttons (volume and lock) are located on the same side, and very close to each other, such concern for the user looks ridiculous: if the finger reaches here, then it doesn’t matter which button to press. Most likely, this is just a copy of the settings that were originally created for those Lenovo models, in which the unlock and volume buttons are on different faces.

On the back of the smartphone, you can find the usual main camera window, framed by a metal ring protruding beyond the surface, as well as a dual LED flash that can function as a flashlight.

The main speaker of the smartphone is displayed in the lower part of the rear panel, the grill covering it is made in the form of an array of small round holes. Despite the presence of two barely noticeable pimples on the sides of the grille, the sound is still significantly muffled when the smartphone is placed face up on a hard surface.

Both traditional connectors are located in their usual places: the headphone output is at the top end, the Micro-USB connector that supports OTG mode is at the bottom.

A small spoonful of honey in the end: the inconspicuousness and inconspicuousness of the Lenovo P90 black case can be compensated by choosing a white version or even bright red instead - it is only unclear whether this device will be officially supplied to the Russian market in red.

Screen

Lenovo P90 is equipped with an IPS touch matrix, with a screen size of 68 × 122 mm, a diagonal of 5.5 inches and a Full HD resolution (1929 × 1080 pixels), which is a dot density of 441 ppi.

The thickness of the frame from the edge of the screen to the edge of the case is just under 5 mm, at the top - only 12 mm, and at the bottom - 16 mm. The frame is thus quite wide.

The brightness of the display can be adjusted manually, or you can use automatic adjustment. Multi-touch technology here allows you to handle up to 10 simultaneous touches. When you bring the smartphone to your ear, the screen is locked using the proximity sensor. According to subjective sensations, in bright sunlight, the screen is very "blind".

Detailed examination using measuring instruments held the editor of the sections "Monitors" and "Projectors and TV" Alexey Kudryavtsev. Here is his expert opinion on the screen of the test sample.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are no worse than those of the Google Nexus 7 (2013) screen (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the off screens (on the left is the Nexus 7, on the right is the Lenovo P90, then they can be distinguished by size):

The screen of the Lenovo P90 is slightly lighter (brightness in photos is 118 versus 113 for the Nexus 7). The ghosting of reflected objects in the Lenovo P90 screen is very weak, which indicates that there is no air gap between the screen layers (more specifically, between the outer glass and the LCD matrix surface) (OGS type screen - One Glass Solution). Due to the smaller number of borders (glass/air type) with very different refractive indices, such screens look better in conditions of strong external illumination, but their repair in case of cracked external glass is much more expensive, since the entire screen has to be changed. On the outer surface of the screen there is a special oleophobic (grease-repellent) coating (very effective, even better than the Nexus 7), so fingerprints are removed much easier and appear at a slower rate than in the case of ordinary glass.

With manual brightness control and with a white field displayed in full screen, the maximum brightness value was about 355 cd / m², the minimum was 14 cd / m². The maximum brightness is not very high, but, given the good anti-glare properties, readability even on a sunny day outdoors could be at a good level, but, unfortunately, everything is not quite right, and why - see below. In complete darkness, the brightness can be reduced to a comfortable value. In the presence of automatic brightness control by light sensor (it is located to the left of the front camera). In automatic mode, when the ambient light conditions change, the screen brightness both increases and decreases. In complete darkness, the auto-brightness function reduces the brightness to 15 cd/m² (normal), in an artificially lit office environment (approximately 400 lux) set to 150-180 cd/m² (suitable), in a very bright environment (corresponding to daylight outdoor lighting , but without direct sunlight - 20,000 lux or a little more) increases to a maximum - up to 355 cd / m². Unfortunately, the decrease in brightness when going from medium to dark does not happen by itself, you need to put the device in standby mode and turn it on. As a result, the auto-brightness function works, but not quite adequately. In the screen settings, you can turn on the high brightness mode, in which case the brightness simply always remains at the maximum value. There is also an option " Extended outdoor mode”, but all its “expansion” lies in the fact that when the brightness is increased in automatic mode to maximum value A message box appears on the screen for a couple of seconds. It turns out that many settings are visibility, profanity. At any brightness level, there is virtually no backlight modulation, so there is no screen flicker.

IN this smartphone IPS type matrix is ​​used. Micrographs show a typical IPS sub-pixel structure:

For comparison, you can see the gallery of microphotographs of screens used in mobile technology.

The screen has good viewing angles without significant color shift even at large deviations of the gaze from the perpendicular to the screen and without inverting shades. For comparison, here are photographs in which the same images are displayed on the screens of Lenovo P90 and Nexus 7, while the brightness of the screens was initially set to about 200 cd / m² (on a white field in the entire screen), and the color balance on the camera was forcibly switched to 6500 K. White field perpendicular to the screens:

The uniformity of brightness and hue of the white field is good. And a test picture:

Color reproduction is good and colors are saturated on both screens (Lenovo P90's colors look more saturated in the photo due to a decrease in screen brightness and a slight increase in color contrast, see below), the color balance is slightly different. 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 on both screens, but the contrast on the Lenovo P90 decreased to a greater extent due to more black highlights and a strong drop in brightness. And the white box:

The brightness at an angle at the screens decreased (at least 5 times, based on the difference in shutter speed), but in the case of the Lenovo P90, the drop in brightness is noticeably greater. The black field, when deviated diagonally, is highlighted strongly and acquires a purple or red-violet hue. The photos below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is approximately the same!):

And from another angle:

When viewed perpendicularly, the uniformity of the black field is good, although not ideal:

Contrast (approximately in the center of the screen) is normal - about 880:1. The response time for the black-white-black transition is 15 ms (8 ms on + 7 ms off). The transition between grayscale 25% and 75% (according to the numerical value of the color) and back in total takes 23 ms. The gamma curve constructed from 32 points with an equal interval according to the numerical value of the shade of gray did not reveal a blockage either in the highlights or in the shadows. The exponent of the approximating power function is 2.29, which is slightly higher than the standard value of 2.2. At the same time, the real gamma curve deviates noticeably from the exponential dependence in some places:

Due to the dynamic and very aggressive adjustment of the brightness of the backlight in accordance with the nature of the displayed image (brightness decreases on dark ones), the resulting dependence of brightness on hue (gamma curve) does not correspond to the gamma curve of a static image, since the measurements were carried out with sequential output of shades of gray almost in full screen. For this reason, we carried out a number of tests - determining contrast and response time, comparing black flare at angles - when displaying special templates with a constant average brightness, and not monochromatic fields in full screen. In general, such a non-switchable brightness correction does nothing but harm, since a constant change in screen brightness can at least cause some discomfort and reduce the visibility of gradations in the shadows in the case of dark images. In addition, this dynamic adjustment, when displaying any image other than a white field in full screen, significantly underestimates the brightness: for example, when displaying a white field on one half of the screen and black on the other, the white brightness is reduced by 13%.

From a practical point of view, the color gamut is equal to sRGB:

The spectra show that the matrix filters moderately mix the components to each other:

As a result, visually the colors have a natural saturation. The balance of shades on the gray scale is acceptable, since the color temperature is significantly higher than the standard 6500 K, but the deviation from the black body spectrum (ΔE) is small, even less than 3, which is considered a very good indicator. At the same time, the color temperature and ΔE change little from shade to shade - this has a positive effect on the visual assessment of color balance. (The darkest areas of the gray scale can be ignored, since the color balance does not matter much there, and the measurement error of color characteristics at low brightness is large.)

In this smartphone, in the screen settings, you can select Custom Mode, where you can adjust the hue and saturation (color contrast). We note the low quality of the translation, since Cool in this context it is not Steep, and, for example, Cold, and strange S.T. is an unsuccessful attempt to translate the term Saturation (Saturation):

English version:

An example of what we got by choosing to configure Hue meaning Warm, is shown in the graphs above as dependencies, signed as Warm. After this correction, the color balance improved, as the color temperature became closer to 6500 K, and ΔE did not change significantly. The maximum brightness, however, has slightly decreased (up to 318 cd / m²). Customization S.T. better translate to Soft so the images look more natural. Note that the mode adaptive mode essentially coincides with the correction performed, that is, it is another useless setting.

Let's summarize. The screen does not have a very high maximum brightness, but it has good anti-glare properties. At the same time, dynamic adjustment of the backlight brightness noticeably underestimates the brightness when displaying any image other than a white field in full screen. In general, it turns out that readability in conditions with bright ambient light is unlikely to be very good. In complete darkness, the brightness can be lowered to a comfortable level. It is also acceptable to use the mode with automatic brightness adjustment, which works well at least during transitions from medium to high illumination and vice versa. The advantages of the screen include a very effective oleophobic coating, the absence of flicker and air gap in the layers of the screen, as well as the sRGB color gamut and good (especially after manual correction) color balance. Significant disadvantages are the non-switchable dynamic adjustment of the backlight brightness, a strong decrease in brightness at an angle and low black stability to the deviation of the gaze from the perpendicular to the screen plane. Together, these shortcomings reduce the final screen quality rating to average.

Sound

Lenovo P90 sounds modest. The sound is almost inaudible low frequencies, the smartphone emits a loud and piercing sound mainly at high notes, a thick rich sound is not obtained. The situation is better in headphones, but the maximum volume level seemed insufficient to us. IN conversational dynamics the voice of a familiar interlocutor remains distinguishable, the timbre and intonations are recognizable.

To play music, only a regular player is provided here. Google Music generally without any user-accessible settings that can affect the sound quality.

FM-radio is standard in the smartphone, there is no possibility to record programs from the air. But smarfton can record telephone conversations from the line, and can do it automatically, recording all calls in a row or by choice.

Camera

Lenovo P90 is equipped with two modules of digital cameras with a resolution of 13 and 5 megapixels. The front 5-megapixel module is equipped with an f / 2.6 aperture and a fixed focus, it does not have its own flash. In low-light conditions, Light Fill is a lifesaver, in which most of the screen around the viewfinder glows brightly, illuminating the face of the shooter. The screen can be illuminated in yellow or pink, as you like. You can initiate a selfie here not only by pressing a virtual button on the screen, but also by touching the viewfinder screen anywhere, as well as gestures, voice and even blinking your eyes - all this is configured in the corresponding menu. But the quality of the resulting images at the same time leaves much to be desired.

The main camera is equipped with a 13-megapixel module with an f / 2.2 lens, fairly fast autofocus, dual multi-color LED flash and even an optical stabilization system. The interface for controlling the camera is simple: all settings are grouped into three columns, and in addition to the usual shooting mode, you can turn on HDR mode, panoramic, and apply a variety of color effects.

The camera can shoot videos in the maximum resolution of Full HD (1920×1080, 30 fps), an example of test clips is shown below.

• Clip #1 (24 MB, 1920×1080, 30 fps)
• Clip #2 (22 MB, 1920×1080, 30 fps)

	The camera works well with shadows. Excessive sharping is noticeable on the trees in the distance.
	On the grass and trees, sharpening is clearly visible on almost all plans, but in general, the sharpness is not bad.
	At the left edge there is a blur zone.
	On the letters, the soapiness of the image is well felt already in the middle plans.
	The camera does a good job with macro photography.
	Another example of a good macro.
	In room lighting, macro photography works well with the camera.
	The number of the car in the foreground is distinguishable, but in the middle it is no longer.
	The camera does a good job of shooting indoors.
	A large blur zone on the left and foliage merging already in the middle plans.
	The text is worked out well, although a little soapy.

Camera abused software processing. And if the noise reduction copes with its task as a whole, then sharping succeeds only fragmentarily, although sometimes its results are very interesting. However, both are overly zealous, which is expressed in the soapiness of medium and long-range plans and the loss of details. In addition, occasionally there are blur zones in the corners of the frame. Given the shortcomings noted, the camera can be recommended for undemanding artistic shooting or for documentary shooting of close and large objects.

Telephone part and communications

The smartphone normally works in modern networks 2G GSM and 3G WCDMA, as well as support for fourth-generation LTE Cat 4 networks with a theoretical possible reception rate of up to 150 Mbps (LTE FDD 800/1800/2100/2600 MHz). In practice, with a SIM card from the domestic operator Beeline, the smartphone is confidently registered and works in 4G networks.

Network capabilities are implemented as standard: there is support for Wi-Fi Direct, Wi-Fi Display, you can organize a wireless access point via Wi-Fi or Bluetooth channels. The Wi-Fi module supports both frequency bands (2.4 and 5 GHz). Connection Supported external devices To USB port in OTG mode, but there is no support for MHL and DLNA. Also, NFC technology was not implemented here.

The navigation module works with both GPS and domestic system Glonass, but does not see satellites of the Chinese Beidou (BDS). There are no complaints about the navigation module, the satellites are located very quickly. The device is equipped with a sensor magnetic field, on the basis of which the magnetic compass of navigation programs functions.

The phone application supports Smart Dial, that is, while dialing telephone number immediately carried out and the search for the first letters in the contacts. Support for input by seamless sliding from letter to letter (Swype) is also implemented here. Sliding for ease of use with one hand virtual keyboard phone dialer closer to either side of the screen, here it's called a "live keyboard". It is also possible to record telephone conversations in automatic mode.

OS and software

The device uses the Google software platform as a system. android version 4.4.4 with a branded graphic installed on top of it user interface entitled Lenovo Vibe ui. The well-known, bright, lurid branded shell is exactly the same here. appearance and has all the same features as others modern models Lenovo mobile family. There is no separate program menu, the settings section is divided into two parts: for normal settings and for specific ones, such as working with gestures. In this section, settings for Lenovo models may vary. For example, unlike the Vibe Z2 Pro, here the display is not activated by double tapping on the glass, only the volume buttons turn the screen on. By shaking the smartphone, you can lock the screen back, and by tilting it to the side, you can move the dialer buttons to the side. In place of a smart button, by clicking on which the menu opens quick access to the basic functions of the smartphone.

As usual, there are a lot of pre-installed third-party programs, they are all free, anyone could download them from the online store on their own. Many of these applications will not be in demand and only clog up the device's memory. Traditionally annoying is the unswitchable and unremovable Security module that is forcibly pre-installed in every Lenovo smartphone and constantly hanging in the system tray.

Performance

The Lenovo P90 hardware platform is based on the Intel Atom Z3560 64-bit quad-core SoC. CPU here it has 4 cores with x86 architecture and c operating frequency up to 1.83 GHz. Graphics are handled by the PowerVR G6430 video processor. Random access memory in the device 2 GB, the user has about 25 GB of free flash array. There is no possibility of expanding the memory using cards, but the mode of connecting external devices to the USB port (USB Host, USB OTG) is supported.

Based on the results of testing, the Lenovo P90 platform demonstrated quite good, above average performance, based on the results of such popular benchmarks as AnTuTu. IN AnTuTu smartphone scored about 40K points, while the most advanced modern top solutions already demonstrate numbers over 60K (Samsung Galaxy S6, for example). So, in terms of performance, the Lenovo P90 can be put on a confident average (or slightly above average) level, but no more.

Compared to other similar solutions on the market, Intel platform Atom Z3560 confidently outperformed Qualcomm Snapdragon 615 in all tests (however, it is now outperformed by almost all competing solutions of the corresponding class), being on the same level with the popular MediaTek MT6752, judging by the results in complex tests. Although in specialized graphics and browser benchmarks, the Intel platform confidently outperformed it, rising to about the level of Huawei HiSilicon Kirin 925.

Be that as it may, Lenovo P90 is a powerful enough mobile device that its capabilities are more than enough to perform any task, including the most demanding games.

Testing in latest versions complex tests AnTuTu and GeekBench 3:

For convenience, we have summarized all the results obtained by us when testing a smartphone in the latest versions of popular benchmarks in tables. Several other devices from various segments are usually added to the table, also tested on similar latest versions of benchmarks (this is done only for a visual assessment of the obtained dry numbers). Unfortunately, within a single comparison, it is impossible to present the results from different versions benchmarks, so many worthy and relevant models remain “behind the scenes” - due to the fact that they once passed the “obstacle course” on previous versions test programs.

Testing the graphics subsystem in gaming tests 3d mark,GFXBenchmark, and Bonsai Benchmark:

When tested in 3DMark for the most productive smartphones now it is possible to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (due to which the speed can rise above 60 fps).

	Lenovo P90 (Intel Atom Z3560)	Meizu M1 (Mediatek MT6752)	Samsung Galaxy A7 (Qualcomm Snapdragon 615)	HTC Desire 820 (Qualcomm Snapdragon 615)	Honor 6 Plus (HiSilicon Kirin 925)

Browser cross-platform tests:

As for benchmarks for evaluating the speed of the javascript engine, you should always make allowances for the fact that the results in them depend significantly on the browser in which they are launched, so that the comparison can only be truly correct on the same OS and browsers, and this possibility is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

thermal images

Below is a thermal image of the back surface (upper image is on the right) obtained after 10 minutes of running a battery test in GFXBenchmark:

It can be seen that the heating is localized in the upper left part of the apparatus and distributed over several zones. According to the heat chamber, the maximum heating was 46 degrees, which is relatively high.

Video playback

To test "omnivorous" when playing video (including support for various codecs, containers and accessibility, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Web. Note that for mobile devices it is important to have support for hardware video decoding at the chip level, since it is most often impossible to process modern versions using processor cores alone. Also, do not expect everything from a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it. All results are summarized in a single table.

According to the test results, the test subject was not equipped with all the necessary decoders that are necessary for the full playback of most of the most common multimedia files on the network. To successfully play them, you will have to resort to the help of a third-party player - for example, MX Player. True, it also needs to change the settings and manually install additional custom codecs, because now this player does not officially support the AC3 audio format.

Format	container, video, sound	MX Video Player	Regular video player
DVDRip	AVI, XviD 720×400 2200 Kbps, MP3+AC3	plays normally	plays normally

¹ Audio in MX Video Player only played after installing an alternative custom audio codec; The regular player does not have such a setting.

Video output features tested Alexey Kudryavtsev.

We did not find the MHL interface, as well as Mobility DisplayPort in this smartphone, so we had to limit ourselves to testing the output of video files on the screen of the device itself. To do this, we used a set of test files with an arrow and a rectangle moving one division per frame (see “Methodology for testing video signal playback and display devices. Version 1 (for mobile devices)”). Screenshots with a shutter speed of 1 s helped determine the nature of the output frames of video files with different parameters: the resolution varied (1280 by 720 (720p), 1920 by 1080 (1080p) and 3840 by 2160 (4K) pixels) and frame rate (24, 25, 30, 50 and 60 fps). In tests, we used the MX Player video player in Hardware mode. The test results are summarized in the table:

Red marks indicate possible problems associated with the playback of the respective files.

In terms of frame output, the quality of video playback on the screen of the smartphone itself is excellent, since frames (or groups of frames) can (but are not required to) be displayed with even intervals and without frame drops. The smartphone can even display 4K resolution files up to and including 30 fps. When playing video files with a resolution of 1920 by 1080 pixels (1080p), the image of the video file itself is displayed one-on-one, exactly on the edge of the screen and in true Full HD resolution. The brightness range displayed on the screen corresponds to the range in which the video file is encoded - apparently, the decoder selects it automatically.

Battery life

The Lenovo P90 has a non-removable high-capacity battery with a solid capacity of as much as 4000 mAh. So it is not at all surprising that a smartphone with such a large battery demonstrated a very long, although not record-breaking time. battery life in all test modes. In normal operation, the device will surely live for two full days or more. The creators themselves promise up to 27 days of standby time and up to 45 hours of talk time. It is also worth noting that the testing was traditionally carried out without using any energy-saving functions and modes, although the device has them.

	Battery capacity	Reading mode	Video mode	3D game mode
Lenovo P90	4000 mAh	16:00	13:00	4h 40m
Meizu M1	3140 mAh	16h 40m	13h 20m	4h 45m
Samsung Galaxy A7	2600 mAh	22h 10m	12:00 p.m.	3h 20m
HTC Desire 820	2600 mAh	13:00	7h 40m	4h 10m

Huawei Mate 7	4100 mAh	20:00	12:30 pm	4h 25m

Continuous reading in the FBReader program (with a standard, light theme) at the minimum comfortable brightness level (the brightness was set to 100 cd / m²) lasted more than 16 hours until the battery was completely discharged, and with continuous viewing of video in high quality (720p) with the same brightness level through home network Wi-Fi device lasted almost 13 hours. In gaming mode, the smartphone functioned a little over 4.5 hours. Charging time is highly dependent on charger and can vary from 2.5 to 5 hours (in the latter case, if a third-party power supply is used).

Outcome

The P90 smartphone turned out to be average in all respects. The generally good quality screen with a large diagonal in bright sunlight becomes almost unreadable; durable, reliable and practical body is unattractive in appearance; cameras with big amount megapixels actually give out not the highest quality pictures. The autonomy of the P90 is really on top, but the sound quality, platform performance and networking capabilities to the level of top smartphones, of course, do not hold out. It is gratifying that, realizing this, Lenovo did not raise the price too much: at the time of the announcement of the article, the P90 is already available in retail at a price of about 20 thousand rubles, and given the current situation on the Russian market, the device is probably worthy of this money. It is noteworthy that exclusively for Russian buyers in the Lenovo P90 smartphone will be preinstalled world game of Tank Blitz well-known manufacturer games about tank battles Wargaming. Especially for the owners of this smartphone, it is possible to use the WoT Blitz premium account for 30 days, as well as a bonus in the form of a unique premium tank of the 5th level.

Impressions somewhere on the four. In general, the device is good, but the Chinese still have a lot of work to do. Considered a flagship smartphone, I would not call it that. Let's see what the service will say on the line on the display, I'll write about the prospects, upd a little later.

Flaws: You really have to reboot (every 2-3 days, but not as written in the previous review, but because the memory is clogged). You can't drop! With a slight fall, a line appeared on the display, which you can’t get rid of, contacting the service is vague. Confusion with the prices for this model. The official version is cheaper than 17 tr. you won't find. Chinese (LTE operation is in doubt) - costs from 11 tr.

Advantages: Lithium polymer battery (keeps the charge stable for 24 hours) Good equipment, where they even put a protective film Convenient set of built-in software from Lenovo (antivirus, application manager, RAM cleaning, etc.) The device is very thin!

This is not a telephone, since it is unrealistic to call on it. Worst Phone what I had. At the same time, all the glitches are purely in the software, but the manufacturer is in no hurry to send patches and other fixes

Flaws: 1. Loses the network every 2-3 minutes in LTE mode, in 3g mode - once every 5-7 minutes, people can't get through to you at all 2. About the battery flagship - a complete heresy. Sits down completely in 1 day. Not a single phone worked less, while the indication of the remaining charge does not work - in half of the cases, after notification that 15% is left, it is immediately cut down tightly.

Advantages: Big good screen Everything desired applications from the box

As already correctly said, the photos and videos do not show the charms of the design, the phone looks very stylish and cool, and at the same time the case is thin. But all this must be hidden behind a case, because the case is extremely fragile. And this is with a completely monolithic design. The cameras are normal, but they don’t cause a wow effect, they take pictures normally, and unfortunately not always. The battery is good only if you use it with minimal loads, calls, correspondence, listening to music. But when you need to use it for navigation, watch a video in normal quality or let your child play, the case starts to warm up like crazy and charging is lost at a colossal speed. And the firmware is not very good, although a lot of time has already passed since the release, but something that was missing was not finished. The trouble is shorter.

Flaws: Extremely fragile case unstable firmware - connection is lost and as a result several times a day you need to reboot. A screen with beautiful detail and colors, but the brightness margin in the sun is simply not enough, the keyboard hangs, it gets very hot under load.

Advantages: Elegant design - the device looks really very good. The optimal amount of pre-installed software, there is nothing superfluous. Slim body, comfortable ergonomics, high quality screen and buttons are comfortable.

Experience of use: several months

I read it, everything is fine with the speaker for a year, there are no problems with the programs, the charge is still good.

Flaws: Curve Russification, but it does not interfere with using the phone.

Advantages: Holds a charge for a long time - 4-5 days if without the Internet, but with music, with the Internet for 1.5-2 days freely. Like the camera - big beautiful photos without graininess, etc., which is observed in a model with similar indicators in fly, for example.

Experience: over a year

I took a Samsung replacement (broken), with similar characteristics. In comparison with it, the battery lasts longer in the mode permanent job on the Internet, although there is also a 4000 battery. For half a year of work, no complaints.

Flaws: Firmware update without root is not possible

Advantages: Battery, design, monolithic body, camera. Slim, stylish, pleasant to the touch.

Experience of use: several months

Flaws: It happens very rarely that he does not see the Internet, but this is tolerable, I also reboot it, because it hangs. That week I couldn’t charge it, I tried it on three charges, and nothing, I had to send it in for repair. I will say that he himself is good, but the spare parts are so-so, so it’s up to someone who is lucky

Advantages: I’ve been using it for a year now, what they write above about the Internet, etc., I didn’t have this, thank God, everything suits me, it’s very convenient to hold in my hands, and generally very convenient. If you go to record a video, shoot something, for example, graduation, then you can safely do it, in this regard it is also very convenient, because the hand does not get tired holding it. Everything I installed worked well. The camera is good. I'm happy with my purchase and don't plan on changing it.

User experience: less than a month

When I got my first phone touch screen I was very worried about its durability. I'm clumsy, my button Nokia where just do not understand. Was purchased HTC desire s. Nokia's jaw would drop if she saw what happened to this htz ..
He was dropped into the stairwell from the second floor in the production room (ceiling height 6m), his wife accidentally stepped on him with her heel. Whatever happened to him, but this phone did not know how at the time of purchase faithfully served me. And then with the change of work, the wife made a gift lenovo p90. We chose together because there was a number of nomenclature of parameters that I was flattered by: battery capacity, memory size, smart poots. The box is a phone house!, with rooms for headphones, a charger, brochures, some kind of adapter, two protective films and something else. The Apple gadget I gave my mother for her birthday wasn't packaged like this Chinese guy. The first week I was completely delighted with the phone, then after installation standard set applications, navigator, folder explorer, mail, etc. the phone is dead ... no, it didn’t stop working, but it wakes up in the morning as if from a binge or with eternal lack of sleep. Tupit, buggy loses connection and Internet. If the Internet is dull, then along with everything else. The battery is discharged, it rings bad, it hangs when you try to answer. Very bad! Infinitely disappointed. While I was typing this review, the phone ate 30% of the battery.

Flaws: The glass does not have the declared wear resistance, the film blistered after a month, the Internet and the network constantly fall off, the screen in the sun generally blinds, when you try to open a folder with SMS or any other application, the phone tenses and heats up as if it was offered a quick exchange rate according to aerodynamic calculation for a whole stream students calculate.Very rough gps dotchik. Claimed " night mode"does not work. The battery sometimes runs out at such a speed that one gets the impression of a physical splash of charge from a flat saucer-phone. The keyboard sometimes ... often ... yes, almost all the time lags behind the desired typing (I type slowly, and the keyboard still the disadvantages can be listed endlessly, none of them is a continuation of dignity.

Advantages: Good headphones, thick paper box

User experience: less than a month
