TFT IPS- High quality liquid crystal matrix. It has wide viewing angles, one of the best indicators of color rendering quality and contrast among all those used in the production of displays for portable equipment.
Super AMOLED- if a regular AMOLED screen uses several layers, between which there is an air gap, then in Super AMOLED there is only one such touch layer without air gaps. This allows you to achieve greater screen brightness with the same power consumption.
Super AMOLED HD- differs from Super AMOLED in its higher resolution, thanks to which you can achieve 1280x720 pixels on a mobile phone screen.
Super AMOLED plus- this is a new generation of Super AMOLED displays, differs from the previous one by using a larger number of subpixels in a conventional RGB matrix. The new displays are 18% thinner and brighter than displays made using the old PenTile technology.
AMOLED- an improved version of OLED technology. The main advantages of the technology are significantly reduced power consumption, the ability to display larger color scheme, smaller thickness and the ability of the display to bend a little without the risk of breaking.
Retina-high pixel density display designed specifically for Apple technology. The pixel density of Retina displays is such that individual pixels are indistinguishable to the eye at a normal distance from the screen. This ensures the highest image detail and significantly improves the overall viewing experience.
Super Retina HD- the display is made using OLED technology. The pixel density is 458 PPI, the contrast reaches 1,000,000:1. The display has a wide color gamut and unsurpassed color accuracy. Pixels in the corners of the display are smoothed at the sub-pixel level, so edges are not distorted and appear smooth. The Super Retina HD reinforcing layer is 50% thicker. It will be harder to break the screen.
Super LCD is the next generation of LCD technology, it is characterized by improved characteristics compared to earlier LCD displays. The screens not only have wide viewing angles and better color reproduction, but also lower power consumption.
TFT- A common type of liquid crystal display. Using an active matrix controlled by thin-film transistors, it is possible to significantly increase the performance of the display, as well as the contrast and clarity of the image.
OLED- organic electroluminescent display. It consists of a special thin-film polymer that emits light when exposed to an electric field. This type of display has a large reserve of brightness and consumes very little energy.
How to make a good one inexpensive smartphone? Add big screen, a capacious battery, a modern version of Android and sell the entire set at a reasonable price. I want to talk about the Motorola Moto E4 Plus, a new smartphone where the main feature is a high-capacity battery. I love long-lasting devices, so I asked for the phone to be tested and I want to tell you about it. Who are its competitors? Endless Meizu and Xiaomi, ZTE and Honor - it’s very hot in the “smartphones under 14,000 rubles” group, and there’s just so much that’s not there.
Metallic and plump
Unlike a number of Chinese analogues, here the fingerprint scanner is located in front under the screen, which is convenient. True, the scanner itself is not particularly fast and does not unlock the phone with lightning speed; a slight pause is noticeable. I pressed it, the phone thought for a moment, and it unlocked.
The touch button supports gesture control: you can hide the on-screen keys, launch the task manager, or go back a step by touching this pad and moving your finger left or right.
The case is well assembled, the back panel is removable, it is made of aluminum and is combined with small plastic inserts at the top and bottom. The gray body would look completely ordinary if it weren’t for the large black spot in the center where the camera and flash are located. The designers tried to at least somehow distinguish the phone from a bunch of similar ones.
I won’t scold the phone for its increased thickness and weight of under 200 grams; if this is too much for you, then choose the “regular” Moto E4 - it is thinner. And here lies a large battery, hence the dimensions.
Large display
5.5 inches and HD resolution – isn’t it enough? Well, if you purposefully look for pixels, you will find them, but if you don’t bother about this, you won’t notice them at arm’s length. Of course, life would be better with Full HD, but then there would be performance problems. However, more on this a little later.
The 2.5D glass is slightly curved at the edges, the oleophobic coating is of average quality, but I was more bothered by small scratches and abrasions on the screen. If you are concerned about the appearance of your phone, then you definitely need a film or protective glass.
Confused by wide frames? Yes, they are noticeable, but the model is almost the youngest in the line, so what are the complaints? I liked the large margin of brightness, and also the fact that in the evenings the backlight does not hurt your eyes when you read in the dark. If desired, you can turn on “night mode”, then the image takes on a yellowish tint and your eyes are less tired.
A nice feature: when you pick up the phone from the table, the screen backlight turns on and you can see notification icons, as well as the battery level on the lock screen.
Speed up
When I was setting up the phone, I noticed that it didn't work very fast. Quite strange, considering that it was “naked” and without software. But in the 2 weeks that I spent with the Moto E4 Plus impression remains the same: it is a slow device. The menu and applications lag, I was especially surprised by the wild jerks in the Google application Play Games– I went to look at my achievements, and the phone could barely scroll through the list. Gee, I haven't seen this for a long time.
Considering that there is pure Android 7 without impurities and shells, and even 3 GB of RAM, the conclusion suggests itself: something was not completed by the developers. I hope that the firmware will fix everything, but for now we have to use what we have. This means putting up with lags in toys and more or less demanding programs.
The phone has NFC - Android Pay It works fine, you can pay for purchases without taking out your card, it’s convenient. The phone has two slots for SIM cards, Wi-Fi only works with 2.4 GHz. Another convenient point is that two SIM cards can be used simultaneously with a memory card - usually in Chinese phones To do this you need to remove the second SIM card.
Simple camera, simple sound
The camera is ordinary, “C grade”. HDR is slow, the phone takes passable photos, you can capture text or landscape, but when you look at the pictures on the screen you will notice that the dynamic range suffers and you often end up with a white sky rather than a blue one.
Is it stupid to want miracles from a model of this class? Well, I don’t think Xiaomi or ZTE shoot better for the same money. The front camera with a flash makes taking selfies at night a little more convenient, but overexposed faces are still not pleasing to the eye. As for video recording, HD resolution today is a very modest indicator, there’s not even anything to comment on.
The only speaker is located at the bottom end, it is loud, the ringtone is clearly audible, and it is also convenient to watch videos on YouTube, there is enough volume reserve. If you listen to music, you can play with the Dolby Atmos settings and suddenly you will find a special mode for music. I didn’t hear anything like that, just a normal, normal sound.
The battery does not take out
Let's move on to the final part of the story, to the time battery life. A 5,000 mAh battery is a guarantee of long operating time, I thought. Guess how long the batteries lasted on average? For 1-2 days of work, I couldn’t get more out of the phone. If you watch a video on YouTube, 10% is consumed in an hour - a good figure, but not a record one, and from a high-capacity power source you expect records.
It seems that the screen resolution is low and the processor is low-power, but even this combination turned out to be ineffective, I would not count on a long operating time. Therefore, if you are looking for a phone with excellent battery life, I would look towards a more expensive, but more practical model.
Moreover, in the PC Mark 07 benchmark, where operating time is measured, the smartphone showed good results - 15 hours, but not the best, I expected more from it. For example, budget Xiaomi ones with a 4,000 mAh battery last longer. Charging time from the included power supply is 3.5 hours.
I thought maybe I got a defective sample, but a friend bought himself the same phone, his operating time was the same.
Opinion
The Moto E4 Plus looks good on paper, long-lasting and not very expensive (by Moto standards), but in practice it does not have the most practical properties. The plump smartphone with a power-hungry processor did not disappoint with its battery life in everyday use, although the test results were decent.
In my opinion, it’s more interesting to look towards the Moto G5 Plus, and in general there are plenty of alternatives for that kind of money. Still, 13,990 rubles, which is what they are asking for the Moto E4 Plus, is a significant amount for a smartphone with budget hardware, but for this money you want more. At a minimum, so that the phone does not slow down, I received good camera, and would also weigh less.
If I were Moto, I wouldn’t release such a device so as not to upset the brand’s fans, but where am I and where are the company’s marketers. I remember writing about it - the phone was a little expensive, but it left a pleasant feeling, but the E4 Plus didn’t grab my attention.
General characteristics
Type
Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to select the phone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.

There is no shortage of top-end devices in the smartphone market today. When it comes to budget devices, they all offer the same expected features, but their quality can vary significantly. Today we will introduce you to new budget Motorola smartphones, presented in mid-June - Moto E⁴ and Moto E⁴ Plus. The Moto E line is positioned as affordable smartphones slightly higher than the cheapest Moto C and slightly lower than the mid-range Moto G.
In Russia, Moto E⁴ and Moto E⁴ Plus were presented on and are already on sale.
Design of Moto E⁴ and Moto E⁴ Plus
In fact, Motorola has launched almost all of the Moto E⁴ and Moto E⁴ Plus brands different devices for different markets, they differ in both processors and rear panel design. We tested the Moto E⁴ and Moto E⁴ Plus smartphones intended for the Russian market. Both smartphones received a chassis made of plastic with rear panel made of metal and plastic.
The back panels of smartphones are removable; after removing the panel, we see connectors for SIM installation cards (both models support two SIM cards ami) and a memory card that can be installed instead of a second SIM card.
To install SIM cards and a memory card in Moto E⁴, you need to remove the battery, it can be replaced by the user, the Moto E⁴ Plus battery is secured with screws and to replace it, it is better to contact an authorized service center.
There is an NFC antenna on the back of the Moto E⁴ Plus, but the Russian version of the Moto E⁴ does not have NFC support.
At the top of the front panel of Moto E⁴ and Moto E⁴ Plus there are front cameras with a resolution of 5 megapixels with LED flash, LCD indicator, sensors and speaker. At the bottom there is a fingerprint scanner. The rear panel houses the main cameras, the Moto E⁴ has a resolution of 8 megapixels, and the Moto E⁴ Plus has a resolution of 13 megapixels, with dual-tone LED flashes. The speaker grille of the Moto E⁴ is also located on the rear panel, and on the Moto E⁴ Plus it is located on the bottom end of the case.
Both smartphones received a Micro USB connector and a microphone located at the bottom end of the case.
The 3.5 mm jack for connecting headphones is located on the top end of the device.
The volume and on/off keys are located on the right.
In general, both smartphones are built very high quality and look solid, there is not the slightest play or squeak. If it were not for the rather modest specifications and display resolution, they could easily be confused with Moto G series smartphones.
Moto E⁴ and Moto E⁴ Plus specifications
As we have already said, Motorola has released devices with different specifications under the Moto E⁴ and Moto E⁴ Plus brands for the European, including Russian and American markets. The American version of Moto E⁴ received either an eight-core Qualcomm processor® Snapdragon™ 425 or eight-core Qualcomm® Snapdragon™ 427 processor running at 1.4 GHz, and Moto E⁴ Plus - Qualcomm® Snapdragon™ 427 running at 1.4 GHz. The European version, including the version for Russia, is powered by an eight-core MediaTek MT6737 processor with a clock frequency of 1.3 GHz. One can argue for a long time about the advantages of Qualcomm or MediaTek, but the version for Europe and Russia received 3 GB of RAM, compared to 2 GB in the American version, and this is a definite plus.
The main difference between Moto E⁴ and Moto E⁴ Plus is the size of the device, the diagonal and quality of the display, the resolution of the main camera and of course the battery. The biggest feature that sets the Moto E⁴ Plus apart is its huge 5000 mAh capacity, which will allow the smartphone to last up to two days on a single charge.

Moto E⁴ Plus performance
Display of Moto E⁴ and Moto E⁴ Plus
The Moto E⁴ and Moto E⁴ Plus displays have the same HD 720p resolution of 1280×720 pixels, but due to the difference in display diagonal, the pixel density of the Moto E⁴ is higher than that of the Moto E⁴ Plus. However, the Moto E⁴ Plus display is brighter and has more contrast.
Moto E⁴ and Moto E⁴ Plus cameras
The younger model received a main 8-megapixel camera and a 5-megapixel front camera. The main camera of Moto E⁴ Plus received a resolution of 13 megapixels, and the front one remained unchanged with a resolution of 5 megapixels.

Moto E⁴ and Moto E⁴ Plus batteries
As we already wrote, Moto E⁴ received a removable battery with a capacity of 2800 mAh, which allows the device to work throughout the day on a single charge. The biggest feature of the Moto E⁴ Plus is its huge 5,000 mAh removable battery, which allows the smartphone to last up to two days on a single charge. The only drawback of both devices is the MediaTek MT6737 processor, which does not support fast charging technology. So this somewhat reduces the benefits of the Moto E⁴ Plus's battery - if you forget to charge it overnight, you won't be able to refill the charge quickly - the Moto E⁴ Plus takes about six hours to charge.
Operating system Moto E⁴ and Moto E⁴ Plus
Both smartphones, out of the box, work on latest version operating system. In addition to the pre-installed Google application package, the Russian versions of Moto E⁴ and Moto E⁴ Plus received a pre-installed Yandex search widget, as well as a Yandex browser.
Moto E⁴ and Moto E⁴ Plus can already be purchased in Russia at prices of 9,990 rubles and 13,990 rubles.
Modest filling, but large battery
In mid-summer, Lenovo introduced its new budget smartphones Moto E series fourth generation. The new items out of the box have Android 7.1 OS, metal cases, and the front cameras are accompanied by an LED flash. Both new products turned out to be quite simple in terms of their technical characteristics, but the Moto E4 Plus, as the name suggests, is the most advanced of them, so let's start with it.

Contents of delivery
The Moto E4 Plus comes in a small box with a tacky design. The cardboard is simply folded along the folds in the manner of mailboxes without gluing.
The kit consists of a connecting cable, network adapter with an output current of 2 A and a maximum voltage of 5.2 V, as well as useless plastic headphones without rubber pads that do not stay in the ears.
Appearance and ease of use
Moto E4 Plus looks quite decent for its level, and maybe even more expensive than it is. The device has a simple but neat design, a body with a metal removable cover, a modern oval touch button with a fingerprint scanner on the front panel. All elements are organically combined, nothing causes rejection.
The Motorola logo is on the back wall; it goes well with the round camera module. The familiar plastic end inserts are attached to the metal of the lid at the top and bottom. Thus, the lid is not solid, which means it is not that durable. The holes for all interface connectors are made here in plastic, not metal.
The smartphone was very large, quite thick and so heavy that it was downright uncomfortable to carry it in your pockets. The weight of 200 g is due to the installation of a large 5000 mAh battery. Smooth, streamlined on all sides and very heavy, the body tends to slip out of your hands; the matte metal surfaces are quite slippery.

SIM cards are inserted into slots located under a removable cover. There are two slots for Nano-SIM and one for a card microSD memory. The battery is securely covered with a casing and is not accessible for self-removal.
The round camera module with dual LED flash does not protrude beyond the rear wall of the case. The flashlight shines very brightly. Here you can also see a small hole for the auxiliary microphone.
The front panel is covered with protective 2.5D glass with sloping edges. There is a peephole visible above the screen front camera with its own LED flash. There is also an LED event indicator at the top.
There is only one button under the screen - more precisely, it is not even a button, but a recess in the glass; you cannot press it. However, it has a built-in fingerprint scanner, and this pad can also be used as a micro-touchpad. The navigation buttons are displayed on the screen; you can use this button panel as standard. However, if you enable the corresponding functions in the settings, you will be able to perform all standard navigation actions (return to the previous screen, go to the home screen, open a list of recently running applications) using just one hardware central button - gestures.
The buttons on the right side have different textures: one is smooth, the other is grooved. The keys have a soft stroke and are easy to feel blindly.
The universal Micro-USB connector, speaker output and conversational microphone are located at the bottom end.
The top end is completely devoted to a 3.5 mm headphone output jack.
The Moto E4 Plus smartphone comes in two color options: Iron Gray and Fine Gold. In both options, the front panel matches the overall color of the case, which makes the image more holistic and complete.
Screen
The Moto E4 Plus features an IPS display with physical dimensions of 68 x 122 mm and a 5.5-inch diagonal. The resolution is 1280x720, the pixel density is only about 267 ppi. The frame around the screen is wide: about 4.5 mm on the sides, 17 mm on the bottom and top.
The display brightness can be adjusted manually or set automatic settings, based on the operation of the ambient light sensor. The AnTuTu test diagnoses support for 10 simultaneous multi-touch touches.

A detailed examination using measuring instruments was carried out by the editor of the “Monitors” and “Projectors and TV” sections Alexey Kudryavtsev. Here is 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 that is scratch-resistant. 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 switched off screens (on the left - Nexus 7, on the right - Moto E4 Plus, then they can be distinguished by size):
The screen of the Moto E4 Plus is slightly brighter (brightness according to photographs is 116 versus 112 for the Nexus 7). The ghosting of reflected objects in the Moto E4 Plus screen is very weak, this indicates that there is no air gap between the layers of the screen (more specifically, between the outer glass and the surface of the LCD matrix) (OGS - One Glass Solution type screen). Due to the smaller number of boundaries (glass/air type) with very different refractive indices, such screens look better in conditions of intense external illumination, but their repair in the case of cracked external glass is much more expensive, since the entire screen has to be replaced. The outer surface of the screen has a special oleophobic (grease-repellent) coating (about the same efficiency as the Nexus 7), so fingerprints are removed much easier and appear at a lower speed than with regular glass.
When manually controlling the brightness and displaying the white field in full screen, the maximum brightness value was about 380 cd/m², the minimum was 8 cd/m². The maximum brightness is low, but given the good anti-glare properties, readability even on a sunny day outdoors should be at an acceptable level. It is also possible to increase the brightness above this limit (see below). In complete darkness, the brightness can be reduced to a comfortable value. There is automatic brightness adjustment based on the light sensor (it is located to the right of the front speaker slot after the front camera eye). In automatic mode, as external lighting conditions change, the screen brightness both increases 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 auto-brightness function reduces the brightness to 140 cd/m² (too bright), in an office illuminated by artificial light (about 550 lux) it sets it to 320 cd/m² (also a lot), in a very bright environment (corresponds to lighting on a clear day outdoors, but without direct sunlight - 20,000 lux or slightly more) brightness increases to 510 cd/m² (which is higher than the maximum at manual setting brightness); if the adjustment is approximately 50%, then the values are as follows: 12, 220 and 380 cd/m² (suitable values), the regulator at 0% is 6, 80 and 370 cd/m² (the first two values are underestimated, which is logical). It turns out that the auto-brightness function works adequately and to some extent allows the user to customize their work to individual requirements. At any brightness level, there is no significant backlight modulation, so there is no screen flicker.
IN this smartphone An IPS type matrix is used. The microphotographs show a typical IPS subpixel structure:
For comparison, you can see the gallery of microphotographs of screens used in mobile technology.
The screen has good viewing angles without a significant color shift even with large deviations of the view from perpendicular to the screen and without inversion (except for the very darkest when deviating along one diagonal) of shades. For comparison, here are photos in which the same images are displayed on the screens of the Moto E4 Plus and Nexus 7, while the brightness of the screens was initially set to approximately 200 cd/m², and the color balance on the camera was forced to switch to 6500 K.
There is a white field perpendicular to the screens:
Note the good uniformity of brightness and color tone of the white field.
And a test picture:
Color saturation on the Moto E4 Plus screen is normal, colors are close to natural, but color contrast is slightly increased. The color balance between the Nexus 7 and the screen we tested was slightly different.
Now at an angle of approximately 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 on the Moto E4 Plus the contrast decreased to a greater extent due to the strong bleaching of blacks.
And a white field:
The brightness at an angle of the screens decreased (at least 5 times, based on the difference in shutter speed), and decreased approximately equally. When deviated diagonally, the black field brightens greatly and acquires a bluish or reddish tint. The photographs below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is the same!):
And from another angle:
When viewed perpendicularly, the uniformity of the black field is good:
The contrast (approximately in the center of the screen) is high - about 1050:1. The response time for the black-white-black transition is 25 ms (13 ms on + 12 ms off). The transition between halftones of gray 25% and 75% (based on the numerical value of the color) and back takes a total of 39 ms. The gamma curve, constructed using 32 points with equal intervals based on the numerical value of the shade of gray, did not reveal any blockage in either the highlights or the shadows. The exponent of the approximating power function is 2.41, which is higher than the standard value of 2.2. In this case, the real gamma curve deviates little from the power-law dependence:
We did not detect the presence of dynamic adjustment of the backlight brightness in accordance with the nature of the displayed image, which is very good.
Color gamut is close to sRGB:
The spectra show that the matrix filters moderately mix the components with each other:
As a result, visually the colors on this screen are almost no different from natural ones. The balance of shades on the gray scale is a bit of a compromise, since Colorful temperature significantly higher than the standard 6500 K, but the deviation from the blackbody spectrum (ΔE) is below 10, which is considered an acceptable indicator for a consumer device. At the same time, color temperature and ΔE do not change much from hue to hue - this has a positive effect on the visual assessment of color balance. (The darkest areas of the gray scale can be ignored, since color balance there is not very important, and the error in measuring color characteristics at low brightness is large.)
This device allows you to choose one of two profiles:
However, in the profile Bright color contrast is greatly exaggerated, distorting photographic quality images. It's better to stay on the profile Ordinary.
To summarize: the screen has a high maximum brightness (in automatic adjustment) and has good anti-glare properties, so the device can be used outdoors even on a sunny summer day without any problems. In complete darkness, the brightness can be reduced to a comfortable level. It is also possible to use a mode with automatic brightness adjustment, which works adequately. The advantages of the screen include an effective oleophobic coating, the absence of air gaps in the layers of the screen and flickering, good uniformity of the black field, high contrast, close to sRGB color gamut and an acceptable balance of shades. The disadvantages are the low stability of black to the deviation of the gaze from perpendicular to the screen plane. Nevertheless, taking into account the importance of characteristics for this particular class of devices, the quality of the screen can be considered high.

The front module of the Moto E4 Plus has a 5 MP sensor and a lens with an f/2.4 aperture, fixed focus and its own front LED flash. Naturally, there is a portrait beautification function (with seven levels of adjustment in manual mode), and it also supports gesture shooting and smile tracking. The quality itself is average: the image is clear, there are no complaints about color reproduction, but these are the only advantages. Dynamic range The matrix is narrow, there are underexposed and fully highlighted areas, and the detailing also leaves much to be desired.
The main camera of the Moto E4 Plus uses a module with a 13 megapixel matrix with a pixel size of 1.2 microns and a lens with an f/2.0 aperture. There is a leisurely autofocus and a dual very bright flash. There is no stabilization system.
The camera is quite simple in its capabilities, the settings menu is convenient and concise. There is no manual pro mode, all settings are collected in a single scroll that slides out with a gesture on the side. Enabling HDR is set to top part screen in a separate mode and is always in quick access.

The Moto E4 Plus camera can shoot video at a maximum resolution of only 720p, there is no Full HD, and there is no stabilization function either. With such a resolution, it is useless to wait for a detailed and rich picture. The image is loose and dark, and the hero of the review is not doing well with video shooting. But by the way, there are no complaints about the sound recording; the sound is high-quality, clear and loud, without noticeable distortion or extraneous noise.
- Video No. 1 (20 MB, 1280×720@30 fps, H.264, AAC)
- Video No. 2 (29 MB, 1280×720@30 fps, H.264, AAC)
- Video No. 3 (18 MB, 1280×720@30 fps, H.264, AAC)
As you can see, the camera copes well with shooting close-up objects, but there are problems with shooting wide shots. Perhaps this is a defect in the lens, but sometimes the camera apparently cannot focus at infinity, although sometimes it still manages to do so. Large areas of blur are almost always noticeable at the edges of the frame, and in medium plans the program begins to spoil the details. As a result, the camera will cope well with undemanding documentary shooting, especially if it is dominated by texts and macro.
Telephone and communications
The communication capabilities of the Moto E4 Plus include support for LTE Cat.4 (up to 150 Mbps), a number of LTE FDD and TDD frequency bands are supported, including all 3 FDD LTE bands of interest to us (band 3, 7, 20). In the city limits of the Moscow region, the device behaves confidently, the quality of signal reception does not cause any complaints.
The smartphone supports only one Wi-Fi band (2.4 GHz), but somewhat unexpectedly it has an NFC module, which, among other things, can work with travel cards. You can standardly organize a wireless access point via Wi-Fi or Bluetooth 4.1 channels. Micro-USB connector supports connection external devices V USB mode OTG. The navigation module works with GPS (with A-GPS). During a cold start, the first satellites are detected within a minute, and the positioning accuracy is quite good. But, unfortunately, the smartphone was not given a built-in magnetic field sensor for compass operation, which is bad.

Moto E4 Plus does not support both SIM cards in 3G/4G mode at the same time. That is, when one card is assigned to transmit data in 4G, the second one can only work in 2G. The interface does not allow you to select a specific SIM card for voice calls and SMS in advance - only during the connection. You can preset a card only for data transfer. Cards work in Dual mode SIM Dual Standby, there is only one radio modem. Also, for user convenience, the manufacturer has added several ready-made operating modes for the two cards.

Software and multimedia
As software platform Moto E4 Plus uses the latest version Google Android 7.1.1 with its own proprietary Moto Experiences shell. The interface is much closer to stock Android versions what is it in appearance, and in terms of capabilities than all versions of Lenovo’s own shells. Programmatically Lenovo smartphones Moto now resemble pure Google phones more than many others.
However, it also includes support for gestures, the ability to reduce the entire working area of the screen for ease of control with the fingers of one hand, and a multi-window operating mode. Conveniently, when you approach the device lying on the table, it instantly displays basic information (time, date, charge percentage) in monochrome on the locked screen. The interface as a whole is simple and calm in design, easy and fast to use. Third party programs practically none, everything necessary is provided here with using Google Apps.

To listen to music, use the standard Google Music player with sound settings and presets of the Dolby Atmos system. Both in headphones and through the speaker, the device sounds average: the volume of the sound in general is enough not to miss a call, but the sound is not of the highest quality, not very clear and not as bright and rich as, for example, the older model Moto Z2 Play with its two stereo speakers, although it doesn't have Dolby Atmos support. There is also an FM radio, but there is no built-in voice recorder in the device.

Performance
The Moto E4 Plus hardware platform is based on the MediaTek MT6737 SoC, made using a 28 nm process technology. The 64-bit platform configuration includes 4 Cortex-A53 processor cores operating at frequencies up to 1.25 GHz. The Mali-T720 video accelerator is responsible for graphics processing. The RAM capacity is 3 GB and the user storage is 16 GB. Of these, in reality, about 1.8 GB of RAM and approximately 10.5 GB of storage are free. It is possible to connect external flash drives in USB OTG mode.
MediaTek MT6737 is one of the simplest modern platforms for entry-level mobile devices. It is quite weak, aimed at the ultra-budget class of devices, and to be honest, Lenovo, of course, is very greedy, offering for 14 thousand rubles a device on one of the cheapest and most useless modern SoCs. It is curious that on the site for North America the company is based on the Qualcomm platform (Snapdragon 427), and this is a more interesting option.
There is no point in expecting high performance indicators from SoC MT6737; the hero of the review demonstrates only about 30K points in AnTuTu. The hardware capabilities of the smartphone are minimal; in all tests it shows low level. Demanding games, such as Mortal Kombat X, and graphics tests noticeably slow down. This device does not have any reserve power for the future.
Testing in comprehensive tests AnTuTu and GeekBench:
All the results we obtained when testing the smartphone in the most latest versions popular benchmarks, we have summarized them in tables for convenience. The table usually adds several other devices from different segments, also tested on similar latest versions benchmarks (this is done only for a visual assessment of the obtained dry figures). Unfortunately, within the framework of one 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 at one time they passed the “obstacle course” on previous versions test programs.

Testing the graphics subsystem in gaming tests 3DMark, GFXBenchmark and Bonsai Benchmark:
When testing in 3DMark, the most powerful smartphones now have the ability to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (which can cause the speed to rise above 60 fps).

Browser cross-platform tests:
As for benchmarks for assessing the speed of the javascript engine, you should always make allowance for the fact that their results significantly depend on the browser in which they are launched, so the comparison can only be truly correct on the same OS and browsers, and this is possible during testing not always. For Android OS, we always try to use Google Chrome.

AndroBench memory speed test results:
Thermal photographs
Below is a thermal image rear surface obtained after 10 minutes of battery testing in the GFXBenchmark program:
Heating is more localized in the upper part of the device, which apparently corresponds to the location of the SoC chip. According to the heat chamber, the maximum heating was only 32 degrees (at an ambient temperature of 24 degrees), which is very little.
Playing video
To test omnivorousness when playing video (including support for various codecs, containers and special features, for example 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 options using processor cores alone. Also, you shouldn’t expect 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 table.
| Format | Container, video, sound | MX Video Player | Standard video player |
| 1080p H.264 | MKV, H.264 1920×1080, 24 fps, AAC | plays normally | plays normally |
| 1080p H.264 | MKV, H.264 1920×1080, 24 fps, AC3 | plays normally | The video plays fine, there is no sound |
| 1080p H.265 | MKV, H.265 1920×1080, 24 fps, AAC | not playable | |
| 1080p H.265 | MKV, H.265 1920×1080, 24 fps, AC3 | plays with significant delays (SW only) | not playable |
Further testing of video playback was performed Alexey Kudryavtsev.
We did not find the MHL interface, like 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 playback and display devices. Version 1 (for mobile devices) Red marks indicate possible problems related to the playback of the corresponding files.
According to the frame output criterion, the quality of playback of video files on the screen of the smartphone itself is good, since in most cases frames (or groups of frames) can (but are not required) be output with more or less uniform alternation of intervals and without skipping frames. When playing video files with a resolution of 1280 by 720 pixels (720p) on a smartphone screen, the image of the video file itself is displayed exactly along the border of the screen, one to one in pixels, that is, in the original resolution. The brightness range displayed on the screen corresponds to the actual range, so that all gradations in the shadows and highlights are displayed.
Battery life
Fixed accumulator battery, installed in the Moto E4 Plus, has a solid capacity of 5000 mAh. Naturally, this is one of key features this device, which is quite simple in all other respects, from the platform and cameras to communication capabilities.
But even with this huge battery, having a low-power platform and low screen resolution, the hero of the review, frankly speaking, is not particularly impressive in terms of autonomy. If you compare its results with the results of the same Moto Z2 Play, which has a battery almost one and a half times smaller, it turns out that they are not so far from each other. In general, the Moto E4 Plus is certainly not a record holder for battery life, although, of course, its level is significantly above average. In real conditions, the device can easily survive a couple of days without recharging.
Testing has traditionally been done at normal power consumption levels without using power-saving features.
Continuous reading in the Moon+ Reader program (with a standard, light theme) at a minimum comfortable brightness level (brightness was set to 100 cd/m²) with auto-scrolling lasted until the battery was completely discharged for about 22 hours, and when continuously watching videos in high quality (720p) with the same brightness level after Wi-Fi network The device operates for approximately 15 hours. In 3D gaming mode, the smartphone can work up to 8.5 hours.
The smartphone charges from its own supplied AC adapter for a very long time, within 3 hours 40 minutes with a current of 1.8 A at a voltage of 5.2 V. Surely the modification of this device on the SoC Qualcomm Snapdragon 427, which supports Quick Charge 3.0, charges much faster, but in Lenovo decided that Russian market The version on SoC MediaTek will be enough. Wireless charging The smartphone also, of course, does not support it.
Bottom line
Moto E4 Plus has a good screen (high display quality is spoiled by low resolution), a large battery that provides decent battery life, and a very attractive case for its level, both in design and ergonomics. And yet, in a smartphone priced at about 14 thousand rubles, of course, you expect to see at least a more interesting hardware platform than the cheap and low-power MediaTek MT6737. In addition, the device cannot boast of a high-quality camera, rich sound, or wide communication capabilities. Video recording with a resolution of only up to 720p, lack of a built-in magnetic field sensor, a second Wi-Fi range— the new product is also not pleasing in detail. The device is suitable primarily for those who need long battery life for their mobile assistant, and do not hope to purchase a multimedia processor, since for that kind of money on the market you can find many more technically interesting models, which, however, very rarely have capacious batteries.
