Water and dust resistant model with average performance

Smartphone Sony Xperia The M4 Aqua was presented quite a long time ago, back in the spring during the MWC 2015 exhibition in Barcelona, ​​but only now has it reached our test laboratory. The device takes the place of a mid-level offer from not the most expensive Sony devices, offering a compromise combination of a good set of characteristics and an acceptable price, as far as “compromise” is generally applicable to the mobile products of this company, which traditionally turn out to be slightly more expensive than their competitors.

This fall, the Xperia M family was expanded to include the M5, which is older in all respects, but also much more expensive. However, this smartphone will appear in our test laboratory a little later, but for now let’s consider what Japanese company currently offers not too demanding users for a price that is approximately half that of modern flagships.

Equipment

The Sony Xperia M4 Aqua Dual smartphone is sold in a very simple, flat, utilitarian-looking box made of thin, unvarnished cardboard. Sony smartphone packaging often has a nondescript, unattractive appearance, which seems to emphasize the company's commitment to taking care of the environment, because such a box is mainly made from recycled materials using soy ink (easily decomposed after disposal).

The set of accessories is more than modest, it consists only of not the most powerful charger(5 V, 850 mA) and connecting Micro-USB cable. The set didn't even include a wired headset.

Appearance and ease of use

The design of the Sony Xperia M4 Aqua is exactly the same as all previous models from this manufacturer released in recent years. Only the shape of the side rim changes from generation to generation. In this case, the sides, like those of the top-end Xperia Z3+, are rounded and smooth; there are no more notches or chamfers on the side frame. Due to this, Sony smartphones began to feel a little more comfortable in the hand, but became more slippery.

The structure of the case is also quite familiar: in addition to the mentioned side frame, which here, by the way, is made not of metal, but of ordinary matte plastic painted with silver paint, there are two glass panels that completely cover the front and back of the case. In any case, glass is a more easily soiled material than plastic, so there are a lot of fingerprints left on the Sony Xperia M4 Aqua body; the body cannot be called non-staining. However, fans of the brand have long been accustomed to all this; they will not encounter anything new here.

In terms of size, the smartphone is a typical representative of modern five-inch models; the device is not too compact, but quite thin, making it quite comfortable to hold the Sony Xperia M4 Aqua in the palm of your hand. The side plastic frame has softer polycarbonate inserts embedded in the corners: the developers claim that they are able to absorb some of the impact energy when the device falls. The inserts are the same color as the frame itself.

Cards, like the rest Sony models, are inserted into the side connectors, only, unlike the flagship models, there are no plastic pull-out trays. The slots have spring-loaded gripping mechanisms; cards must be pressed in with a fingernail until a characteristic click is heard; sometimes you have to resort to the help of third-party objects. In this case, we use the option of installing two Nano-SIM format SIM cards and one microSD memory card at the same time. The card slots are located on different sides and covered with plastic covers with rubber gaskets.

Covers are needed to protect against water and dust getting inside: the device is assigned a protection class of IP65/68. It is curious that Sony has radically revised its policy related to the water resistance of mobile devices. If earlier smartphones with the same degree of protection were positioned literally as devices for underwater photography with an advertising demonstration of photo and video filming in the pool, now a formidable warning in this regard has appeared on the company’s official website, which reads: “The device is prohibited from being completely immersed under water "

From now on, according to the same official description, the device, protected from water and dust, “is not afraid of either pouring rain or washing under the tap,” but at the same time, “incorrect or inappropriate use of the device will void the warranty.” It is clear that service centers Sony has had a lot of trouble with unscrupulous users who violate operating conditions while swimming, but what does IP68 protection have to do with it then? After all, compliance with the IP68 degree of protection implies that the product is suitable for prolonged immersion in water to a depth of more than 1 m.

The picture below shows an advertising poster for the Sony Xperia Z3 Compact smartphone, which has the same IP65/68 protection class. Now this picture is no longer on the Sony website, replaced by an image of a girl standing with a smartphone in the rain. To be fair, it is worth noting that for older models, like the Xperia Z3 Compact, the developers did not change the text confirming the ability to be immersed in fresh water to a depth of 1.5 meters for up to 30 minutes in accordance with the IP68 standard.

And yet, covers with rubber gaskets remain on new Sony devices. In this case, there are two of them: one covers the memory card slot, the other covers both SIM card slots at the same time.

But the open group of contacts has completely disappeared from the sides of new Sony mobile devices, so previously purchased branded docking stations with charging connectors will be useless here. But the protective cover covering the Micro-USB connector has also disappeared. This is convenient because there is no longer a need to open and close such a plug when charging the battery daily. The audio jack is no longer protected from water, but this is no longer news. Also, the strap mount has disappeared from the case.

All mechanical control keys are traditionally located on one side: there is a branded round power button, a two-position volume rocker key, and a separate hardware photo button. The button travel is quite tight, but the response is clear; In general, there are no special complaints about the controls.

It is curious that despite the two symmetrical grilles on the front panel, the sound of the main speaker does not come out through them, as is implemented in Sony flagships, and through a separate, third grille embedded in the bottom end. The front grilles hide the speaker and microphone underneath. There are no touch buttons on the front panel - the buttons are virtual, on the screen.

At the top of the screen, in addition to the sensors and front camera, there is such a useful element as led indicator events. A small round dot emits light signals to indicate charging status and incoming messages.

The camera and flash windows are traditionally located on the back side. The round camera eye is framed by a metal ring; the module does not protrude beyond the surface. The flash has one LED segment and can work as a flashlight.

On Russian market Sony Xperia M4 Aqua Dual is available in three body colors: traditional black and white, as well as an unusual pink color, which the developers dubbed “coral”.

Screen

The Sony Xperia M4 Aqua smartphone is equipped with an IPS touch matrix covered with flat protective glass. The screen dimensions are 62x110 mm, diagonal - 5 inches. But the resolution is only 1280×720, that is, the pixel density is 294 ppi - this is far from modern standards, which are not even adhered to flagship smartphones. The frame around the screen is quite wide: the sides from the edge of the screen to the edge of the body are 5 mm, the top and bottom are 17 mm each.

To adjust the brightness level, you can use automatic adjustment based on the operation of the ambient light sensor; there is also the possibility of smooth manual adjustment. Multi-touch technology here allows you to process 9 simultaneous touches. There is a proximity sensor that locks the screen when you bring the smartphone to your ear. The smartphone screen can be operated with gloves and wet fingers.

Detailed examination using measuring instruments conducted 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 photograph in which a white surface is reflected in the switched off screens (on the left - Nexus 7, on the right - Sony Xperia M4 Aqua Dual, then they can be distinguished by size):

The screen of the Sony Xperia M4 Aqua Dual is not significantly brighter (brightness according to photographs is 111 versus 110 for the Nexus 7). The doubling of reflected objects in the Sony Xperia M4 Aqua Dual 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 strong 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 (slightly lower in efficiency than the Nexus 7), so fingerprints are removed more easily and appear at a slower rate than with regular glass.

When manually controlling the brightness and displaying the white field in full screen, the maximum brightness value was about 600 cd/m², the minimum was 52 cd/m². The maximum brightness is very high, and, given the excellent anti-glare properties, readability even on a sunny day outdoors will be at a good level. For conditions of complete darkness, the minimum brightness may seem too high. There is automatic brightness adjustment based on the light sensor (it is located to the left of the logo on the front panel). In automatic mode, as external lighting conditions change, the screen brightness both increases and decreases. This function is dependent on brightness adjustment. If it is at a minimum, then in complete darkness the auto-brightness function reduces the brightness to 52 cd/m² (a lot), in an office illuminated by artificial light (approximately 400 lux) it sets it to 57 cd/m² (little), in a very bright environment (corresponds to the lighting on a clear day outdoors, but without direct sunlight - 20,000 lux or a little more) increases to 600 cd/m² (to the maximum, which is what is needed). If the brightness slider is at half scale, then the screen brightness for the three conditions indicated above is as follows: 53, 98 and 600 cd/m² (in the dark the value is too high, the rest are suitable). If the brightness control is set to maximum - 94, 290, 600 cd/m² (the first two values ​​are too high). As a result, the auto-brightness function works more or less adequately, but in any case, in the dark the screen remains too bright. At any brightness level, there is virtually no backlight modulation, so there is no screen flickering.

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 significant color shift even with large viewing deviations from perpendicular to the screen and without inverting shades. For comparison, here are photographs in which Sony screens Xperia M4 Aqua Dual and Nexus 7 display the same images, while the screen brightness is initially set to approximately 200 cd/m² (across the white field across the entire screen), and the color balance on the camera is forced to switch to 6500 K. The white field is perpendicular to the screens:

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

Color reproduction is good and colors are rich on both screens, the color balance differs slightly. 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 have not changed very much on both screens, but the contrast on the Sony Xperia M4 Aqua Dual has decreased to a greater extent due to the greater brightening 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), but in the case of the Sony Xperia M4 Aqua Dual the drop in brightness is less. When deviated diagonally, the black field brightens greatly and acquires a greenish tint or remains almost neutral gray. The photographs 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 average, since in several places the black is slightly brightened:

The contrast (approximately in the center of the screen) is good - about 900:1. The response time for the black-white-black transition is 17 ms (9 ms on + 8 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 28 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 2.15, which is slightly lower than the standard value of 2.2. In this case, the real gamma curve deviates little from the power-law dependence:

According to hardware tests, this smartphone does not have any dynamic adjustment of the backlight brightness depending on 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 have a natural saturation. The balance of shades on the gray scale is good, since the color temperature is not much higher than the standard 6500 K, and the deviation from the blackbody spectrum (ΔE) is below 10, which is considered a good indicator for a consumer device. At the same time, color temperature and ΔE change little 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 smartphone has the ability to adjust the color balance by adjusting the intensities of the three primary colors.

That's what we tried to do, the result is data signed as Corr. in the graphs above. As a result, on average we improved the balance of shades of gray, but the spread of values ​​increased, which is not very good. In fact, there is no point in making corrections in this case.

Let's summarize. The screen has a very high maximum brightness and has good anti-glare properties, so the device can be used outdoors without any problems, even on a sunny summer day. For conditions of complete darkness, the minimum brightness may seem too high. It is also possible to use a mode with automatic brightness adjustment, which works more or less adequately. The advantages of the screen include a fairly effective oleophobic coating, the absence of air gaps in the layers of the screen and flickering, as well as a color gamut close to sRGB and good color balance. Among the significant disadvantages we will attribute low black stability 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.

Sound

Sonically Xperia smartphone The M4 Aqua is unremarkable. The single main speaker produces ringing and flat sound with no noticeable presence low frequencies. This is not to say that the sound at maximum level is too quiet, but at the same time, the volume reserve is not quite enough. In headphones the situation is a little better, but still the sound is dull, not too bright, the sound is dull, although without using the ClearAudio+ enhancement system it would be even worse. With the connection of this comprehensive system, the sound of the smartphone becomes a little louder and richer. For manual control, only standard equalizer capabilities with preset values ​​are available here, and not a word is said about such functions used in Sony flagships as Clear Phase, Clear Bass and Clear Stereo, as well as xLoud volume increase technology.

There is an FM radio in the smartphone, it does not work without connected as external antenna headphones and does not know how to record broadcast programs. Recording telephone conversations using standard means in a smartphone is also not provided.

Camera

Sony Xperia M4 Aqua Dual is equipped with two familiar modules digital cameras with a resolution of 13 and 5 megapixels. The front 5-megapixel Exmor R module is equipped with a wide-angle lens with f/2.4 aperture and fixed focus. The front camera can be operated manually and automatic modes shooting control. HDR mode is supported, there is a SteadyShot electronic stabilization function, and the camera can recognize a smile. Using the settings, you can add skin-enhancing effects to your image. For the selfie level, the quality of the resulting photos is generally quite good, the pictures are quite detailed, bright, and the color rendition is natural.

The main camera is equipped with a 13-megapixel Sony Exmor RS module for mobile devices with an f/2.0 aperture lens, autofocus and its own flash. Autofocus has an object tracking function, and according to subjective feelings, it is quite fast here. The camera also has an HDR mode, face tracking, smile tracking, electronic stabilization and a lot of additional modes, the number of which, however, is not as wide as that of the flagship models of the same manufacturer. Naturally, it is possible to download additional modes, including popular ones, such as Time Lapse.

The camera can shoot video in a maximum resolution of 1920×1080 at a speed of up to 30 frames/s. There are no options for shooting in 4K resolution or recording at 60 frames per second. However, the camera generally copes well with video shooting; there are no special complaints about the quality of the resulting video image or the sound recorded. True, the noise reduction system sometimes fails to cope in strong winds.

Examples of test videos:

• Video No. 1 (26 MB, 1920×1080, 30 fps)
• Video No. 2 (48 MB, 1920×1080, 30 fps)
• Video No. 3 (19 MB, 1920×1080, 30 fps)

	Good sharpness across the frame and in the plans.
	The text is well done.
	You can notice an area of ​​blur in the left top corner frame, but otherwise the sharpness is good.
	Long and medium plans are very blurry, as if the focus has gone to the foreground.
	Again the problem with long-range plans. It looks like a focus error, since the camera can focus at infinity.
	The camera copes well with macro photography.
	With the removal of the plan, the foliage does not merge for a long time.
	Once again the long shot is spoiled, although not much.

Sony, as usual, sets a distance between flagships and middling ones. True, Sony’s flagships sometimes suffer from blurriness in the corners of the frame, but otherwise it is clear that a good module is “dressed” in a fairly simple and not ironed program. However, the main complaint that can be made to the camera is its walking sharpness. The foreground, part of the frame, all plans in the center, but not in the periphery, can be sharp, and even the entire frame can be quite sharp. At the same time, sharp parts boast good detail. The noise reduction is quite typical for Sony - not the cleanest, but effective and not soapy. The camera practically does not resort to sharpening.

As a result, the camera can be called good for this segment, although the instability of the result forces you to keep an eye on it and focus more carefully.

Telephone and communications

The smartphone works as standard in modern 2G GSM and 3G WCDMA networks, and also supports fourth-generation LTE Cat networks. 4 with a theoretical maximum possible reception speed of up to 150 Mbit/s. Seven LTE FDD bands are supported, so this smartphone will function in the three most common bands among domestic operators (B3, B7 and B20). In practice, with a SIM card from the Beeline operator in the Moscow region, the smartphone was confidently registered and worked in 4G networks. The quality of signal reception is not satisfactory; the device confidently maintains communication indoors and does not lose the signal in areas of poor reception.

Rest communication capabilities are also quite worthy: it supports two Wi-Fi bands (2.4 and 5 GHz), NFC technology is implemented, Bluetooth has version 4.1 with support for the A2DP stereo audio transmission profile, and the ANT+ standard is also supported. You can organize a wireless access point via Wi-Fi or Bluetooth channels, available Wi-Fi support Direct, DLNA, Media Go, MTP, Miracast. Surprisingly, despite all this, the connection of external devices to USB port in OTG mode.

The navigation module works with both GPS and the domestic Glonass system; the device also sees satellites from the Chinese Beidou (BDS). There are no special complaints about the navigation module; the first satellites during a cold start are identified within the first minute. The device is also equipped with a magnetic field sensor, on the basis of which the compass of navigation programs operates.

The smartphone supports working with two SIM cards, but the mode settings are frankly spartan: you can strictly bind only the data transfer function to a specific card, and for voice calls and text messages You must select the SIM card in the appropriate interface each time during dialing. In general, this does not cause irritation at all, but some may miss such obvious functionality as the initial binding of certain functions to specific cards.

The connectors for SIM cards are equivalent in their capabilities, high-speed data transmission in 3G (4G) networks is supported by the card in any slot, switching is carried out directly from the menu without the need to physically change slots. Work with two SIM cards is organized according to the familiar Dual standard SIM Dual Standby, when both cards can be in active standby mode, but cannot work at the same time - there is only one radio module.

OS and software

The operating system is the fifth version of the Google Android software platform (LolliPop) with Sony's proprietary shell installed on top of it, which has absorbed many of the innovations that appeared with the advent of Android 5.0. Instead of the branded menu of the latter open source software and the notification menu now uses the interface proposed by Google itself, interactive pop-up information tiles have appeared, the ability to create guest accounts, store and restore has been added backup copy V Google account, although much of this has already been previously implemented by the developers of Sony itself.

At the same time, the main recognizable features of the proprietary shell were preserved, including a menu of installed applications with an additional control menu that slides out from the side, and the familiar widgets for the camera, weather, music and What’s new remained scattered on the desktops. The set of pre-installed programs also does not change much over time: here you can still find TrackID (a replacement for the popular Shazam), the Sketch program, the Deezer music service, a full-featured OfficeSuite package for working with office documents, the Movie Creator video editing program and other familiar ones applications. The menu of small applications, opened through the section of recently launched programs, has not disappeared anywhere.

Performance

The Sony Xperia M4 Aqua Dual hardware platform is based on the familiar eight-core Qualcomm Snapdragon 615 (MSM8939) single-chip system (SoC). This 64-bit platform is made using big.LITTLE technology, where four Cortex-A53 processor cores are adjacent to four of the same Cortex-A53 cores, but these “fours” have different maximum operating frequencies. Depending on the nature and degree of load, either 4 “lower” (up to 1 GHz) or 4 “higher” (up to 1.5 GHz) cores are turned on, which allows you to save energy. The Adreno 405 video accelerator with a frequency of up to 550 MHz is responsible for graphics processing here. The Snapdragon 615 SoC is made using a 28 nm process technology and belongs to the category of mid-level solutions.

The smartphone's RAM capacity is 2 GB. The device has 16 GB of flash memory, of which no more than 9.5 GB is available for the user’s needs. However, there are several Sony modifications Xperia M4 Aqua (E2303, E2353, E2312), which have a built-in memory of only 8 GB. Memory capacity can be increased by microSD cards, and the capacity of such cards is officially supported up to 200 GB. In practice, our test Transcend card Premium microSDXC UHS-1 with a capacity of 128 GB was confidently recognized by the device. The mode for connecting external devices to the Micro-USB (OTG) port in the Sony Xperia M4 Aqua Dual unexpectedly did not receive support.

According to the results Sony testing The Xperia M4 Aqua showed rather modest results, even lower than one would expect from the already far from the most powerful Qualcomm Snapdragon 615 platform. According to the popular comprehensive benchmark AnTuTu, this is only 28K points, or about 29K in the 64-bit version of that same test.

It is curious that by this time several mobile devices based on an updated and slightly more powerful version of the second generation Snapdragon 615 platform had already been released onto the market. Its maximum operating frequency of processor cores has been increased to 1.65 GHz, and, for example, the Xiaomi Mi 4i and Lenovo Vibe Shot that we previously tested are based on this SoC. Based on their results, put into a comparative table, you can see how much more productive these smartphones have become. But, unfortunately, Sony did not follow this path, installing a modification of the platform into its smartphone, which demonstrates much worse results, which, again, is clearly visible from the comparative table (however, the Xperia M4 Aqua model, as we already mentioned, was announced relatively long ago).

If we compare with competing solutions, then there is almost complete parity with the MediaTek MT6753 platform, which is similar in level and positioning, which, unlike the more widely used MT6752, also has a noticeably reduced core frequency (MT6752 itself, in comparison with these two cut-down modifications, produces much better results). Similar numbers in all tests are shown by another mid-level SoC, which is used in its smartphones Huawei company- HiSilicon Kirin 620.

Testing in latest versions comprehensive tests AnTuTu and GeekBench 3:

For convenience, we have compiled all the results we obtained when testing the smartphone in the latest versions of popular benchmarks into tables. The table usually adds several other devices from different segments, also tested on similar latest versions of 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 3DMark game tests,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.

Thermal photographs

Below is a thermal image of the rear surface obtained after 10 minutes of running the battery test in the GFXBenchmark program:

It can be seen that the heating is clearly localized in the upper part of the device, which apparently corresponds to the location of the SoC chip. According to the heat camera, the maximum heating was 48 degrees (at an ambient temperature of 24 degrees). This is very hot for this test compared to other modern smartphones.

Playing video

To test the omnivorous nature of video playback (including support for various codecs, containers and special features, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Internet. 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 single table.

According to the testing results, the subject was not equipped with all the necessary decoders that are necessary for 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 is also necessary to change the settings and manually install additional custom codecs, because now this player Does not officially support AC3 audio format.

Format	Container, video, sound	MX Video Player	Standard video player
DVDRip	AVI, XviD 720×400 2200 Kbps, MP3+AC3	plays normally	plays normally
Web-DL SD	AVI, XviD 720×400 1400 Kbps, MP3+AC3	plays normally	plays normally

Tested video output features 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 “Method for testing video playback and display devices. Version 1 (for mobile devices)”). Screenshots with a shutter speed of 1 s helped determine the nature of the output of frames of video files with various parameters: Resolution varied (1280 by 720 (720p) and 1920 by 1080 (1080p) pixels) and frame rate (24, 25, 30, 50 and 60 fps). In the tests we used the MX Player video player in the “Hardware” mode. The test results are summarized in the table:

720/30p Fine No 720/25p Fine No 720/24p Fine No

Note: If in both columns Uniformity And Passes Green ratings are given, this means that, most likely, when watching films, artifacts caused by uneven alternation and frame skipping will either not be visible at all, or their number and visibility will not affect the viewing comfort. Red marks indicate possible problems related to the playback of the corresponding files.

According to the criterion of frame output, the quality of playback of video files on the screen of the smartphone itself is good, since frames (or groups of frames) can (but are not required) be output with more or less uniform alternation of intervals and without skipping frames. The exception is files with 50 and 60 fps, in which the probability of missing a couple of frames per second is very high. When playing video files with a resolution of 1280 by 720 (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 standard range of 16-235 - all shade gradations are displayed in shadows and highlights - which is what is required for correct playback of typical video files.

Battery life

Fixed accumulator battery, installed in the Sony Xperia M4 Aqua, has a capacity that is not very large by modern standards, only 2400 mAh. As a result, the smartphone cannot boast of a record duration battery life, it is at an average level, not higher. It is also worth noting that testing was carried out without using any energy-saving functions, and Sony smartphones traditionally have several options for them, united under the common name Stamina. By the way, with the advent of the fifth version of the Android OS, Google’s own power saving mode also appeared, included by default in the system - it is hidden in the menu subsection dedicated to battery use.

According to the testing results, continuous reading in the Moon+ Reader program (with a standard, light theme, in auto-scrolling mode) at a minimum comfortable brightness level (brightness was set to 100 cd/m²) lasted about 11.5 hours until the battery was completely discharged, and with continuous viewing video from YouTube high quality(HQ) with the same brightness level via home Wi-Fi network The device lasted 9 hours. In 3D gaming mode, the smartphone worked for 4 hours. The developers themselves insist that in normal average use, the smartphone can last two days on a single charge, talk time is about 13 hours, and standby time is up to 493 hours. The time to fully charge the battery is, according to our measurements, approximately 2 hours.

Bottom line

At this moment Sony price Xperia M4 Aqua in official Russian retail varies between 20-21 thousand rubles. For this money, the Japanese offer a fairly typical set of capabilities, characteristic of a true average peasant, based on the mid-level and far from the most productive Qualcomm Snapdragon 615 platform. There are a sufficient number of smartphones on this platform on the market now, and many of them are cheaper than the Sony device, but the hero The review has a couple of distinctive points. Firstly, moisture protection. This issue, however, has recently been greatly discredited by the actions of Sony itself, which unexpectedly banned the immersion of its devices in water, for which they continue to claim compliance with IP68 specifications. Against this background, adding the word “Aqua” to the model name, by the way, looks especially ridiculous. Well, secondly, the popularity of the Sony brand is still making itself felt: the recognition of this brand is so high that the company can afford to produce fairly similar mobile products, which each time become more and more difficult to distinguish from each other, both in terms of characteristics, as well as in appearance.

Distinguished in its class Sony smartphone Xperia M C1905 stands out, first of all, for its bright appearance. Users have access to four color options, including, in addition to the classic black and white, bright yellow and bright purple. The phone turned out to be small - its screen is 4 inches, weight 112g. With a thickness of 9.3 mm, the Sony Xperia M cannot be called super thin, but it fits comfortably in your hand and can easily be carried in your pocket.

Abilities, performance

Sony Xperia M C1905 is positioned as a mid-budget device, and its characteristics represent it as such. Some discrepancy is the dual-core Qualcomm Snapdragon S4 processor, working with clock frequency 1 GHz and a fairly powerful Adreno 305 graphics chip, the power of the first is simply not enough to fully realize the potential of the second. Therefore, complex graphic games are a little difficult to play, but web pages load almost instantly. The amount of RAM is okay, 1GB is allocated.

Screen, cameras, sound

The Sony Xperia M C1905 screen has a TFT matrix with a low resolution of 854x480, but despite this, it managed to outperform even some more expensive models. The main feature is a large reserve of brightness with a maximum value of 422 cd/m2, which allows you to read without problems even in bright sunshine. Contrast is not up to par, color rendering is somewhat biased towards cool shades, viewing angles also leave much to be desired. The smartphone cameras do not differ in high resolution - 5MP and 0.3MP, but the main one is equipped with a shooting function in HDR mode, increasing the quality of images taken in difficult conditions. The high-quality sound of the smartphone is provided by HD Voice technology, so that both during a conversation and when playing sounds, audibility and clarity are excellent.

Assessing the impression of the Sony Xperia M C1905, we must admit that it is rather positive. Pros - design, case quality, brightness, high-quality graphics, good sound. Cons: budget screen, weak cameras. It’s worth taking a closer look at the model, but when choosing, you need to take into account the strengths and weaknesses, in accordance with your own priorities.

Bright colorful screen. Compact and high-quality smartphone. Does not slow down after many years of use. NFC. A-GPS. Long battery life when listening to music. Charging/message/notification indicator light.

Good phone for your time for your money for a person who values ​​light weight and compactness. I had a chance to hold the Iphone SE in my hands - the Xperia M is much better in ergonomics (does not slip, does not cut with sharp edges, the buttons are all where they should be, only after 2 years of wearing without covers appearance began to deteriorate noticeably).

1. Small size. This was very important for me, I don’t like “shovels” 2. Indestructibility. No matter how many times I dropped it, nothing happened to it. True, I carry it in a case. 3. Charging. If I don’t actively use the Internet (i.e. I go out a couple of times a day to check email, messages on VK, etc., for a short time), it can last 4 days without recharging. 4. Android old version, without any problems that phone carriers with the latest versions complain about. 5. Communication. It catches well, they hear me well. This is a real problem on some phones. 5. Price. The phone was very inexpensive. Because I needed a high-quality, necessarily small in size, dialer with Internet access, for my money I got what I wanted.

Battery. Battery. And again the battery. It sat down very quickly with my average use (browser, VK, What's App). I charged it every day. I took the charger to work.

after “swimming” - the battery holds up sometimes well, sometimes poorly..... in the cold it discharges, sometimes when charging it starts to get warm (again, it’s my own fault, I think so). The flash stopped working just recently. and very, very little memory, I can’t properly pump up the phone with applications. something has to be deleted. not convenient.

0. Hopelessly outdated. 1. Unlock. In some types of trousers, the phone periodically unlocks itself, starts recording videos or taking photos, or calling emergency numbers. 2. GPS works every once in a while. I don’t use it at all, I use Android geolocation services. 3. Crooked audio driver. No, the speaker itself is of a very decent level, and in Skype/WhatsApp the sound of the internal speaker is very good. The problem is that the built-in speaker audio driver is not optimized to work in cellular networks cutting frequency range above. 4. Built-in memory 4Gb. The ability to write anything other than photos and videos is blocked on the memory card.

Camera!!! How could Sony put such squalor into their phone? Skype: if you actively use Skype and simultaneously access the Internet from the same device, then be prepared for Skype to crash, freeze and disappear. Memory: why does the device need Adreno 305, when you won’t be able to use it properly and all because of the tiny memory, which quickly gets clogged various applications and their cache, the problem is partly solved by rooting and replacing the memory, but I only tested the replacement on firmware 4.1.2; on 4.3 the replacement was not possible, but with new firmware WiFi reception is noticeably better. No 4G. If the memory is full it will stutter wildly, so always leave free place on the internal disk at least 400 MB.

1. GPS. Satellites are picked up irregularly. It let me down a couple of times and I had to drive the car “blindly.” 2. After a year of use, it began to become dull. For example, I click something on the screen, and the menu “crashes” only after a couple of seconds. 3. Camera. Forget about pretty pictures. But if, for example, you need to photograph an ad or a price tag in a store, it will help. Selfies and landscapes are not for this phone.
