Xperia m4. Preview of Sony Xperia M4 Aqua and Xperia Z4 Tablet

One of the main features Xperia line– Stamina mode, in which the smartphone demonstrates very impressive time results battery life. Xperia M4 Aqua easily withstands a day of work at active use, and in economy mode The battery will easily last for two days. This is a very good result, not only in the middle class, but in the market as a whole.

conclusions

Xperia M4 Aqua appeared on the market at the right time. As practice shows, people who are accustomed to A-brands find it difficult to come to terms with the fact that their favorite products have become unaffordable, so they switch to smartphones Chinese manufacturers I still don't want to. In this case, the Xperia M4 Aqua will become best choice. It is very similar to the flagship model, many will not see any difference at all. Not only the design is similar, but the interface and pre-installed software are similar. Even the impressions of the work are very close. But the price varies almost twice. I am sure that many will even think that the flagship is not worth such an additional payment.

Today in Barcelona MWC exhibition 2015 Sony announced two interesting devices- mid-range smartphone Sony Xperia M4 Aqua and top-end Xperia tablet Z4 Tablet. Flagship Xperia phone The Z4 did not receive such an honor and, probably, its announcement will be timed to coincide with the release of the new James Bond film, but now, looking at the presented new products, we can make some assumptions about the future leader of the line. Let's take a closer look at them.

Sony Xperia M4 Aqua is designed to become perhaps the best mid-ranger in the class with flagship design and some unique characteristics. Externally, it is almost impossible to distinguish it from the Xperia Z3 - a slightly smaller screen and a microUSB port without a plug. The latter is one of the key features of the new line Sony devices. The use of Capless USB technology, which debuted in the Sony SmartBand and was tested on it, made it possible to leave this port without a plug, while maintaining a high degree of moisture protection (IP65/68). The front panel of the device is protected by mineral glass, the back - by ordinary transparent plastic. The frame of the case is also made of plastic. As a result, we have an almost complete copy of the Xperia Z3 in design, but from simpler materials.

The screen here has also become simpler: 5", HD resolution, IPS with good behavior at tilts and different angles. There was no oleophobic layer on the prototypes, there is hope that commercial samples will receive it. The phone has become much thinner than the M2 Aqua (now here only 7.3 mm), but the battery has added 2400 mAh, which, according to the manufacturer, should be enough for 2 days of operation.

In terms of hardware, we have a smartphone based on the 8-core 64-bit Snapdragon 615 chipset, this is Sony’s first eight-core chipset. Combined with the HD screen resolution, the device's performance should be sufficient for all tasks (a 25% performance improvement is claimed compared to the M2). In the case of a single-SIM version of the smartphone, the user will have 8 GB available internal memory, with a dual SIM card - 16 GB. Interestingly, nano SIM cards are used.

Sony Xperia M4 Aqua is also the company's first smartphone to run on Android Lollipop already out of the box. The update to the Z series smartphone line will take place in the next couple of weeks, and first it will affect the flagship models, and then all the others from this family, plus several devices that are not part of the flagship collection. Interface Xperia Home has undergone multiple changes in accordance with the concept Material Design, it looks modern, fresh and interesting. All Sony branded chips, design themes and much more have not gone anywhere. On prototypes the system worked quite slowly, but it is promised for release excellent speed work. Among software chips We can highlight the joint work of the front wide-angle (88 degrees) 5-megapixel and rear 13-megapixel cameras; some of the same effects and an electronic stabilizer are available for them.

The phone will be available for sale soon in three colors(white, black and pink), price has not yet been announced. Due to fluctuations in the ruble exchange rate, it is difficult to predict, but you can remember the starting price for the Xperia M2 and adjust it to suit today's market conditions. In any case, we have enough before us interesting smartphone, which will clearly find its buyer.

The Xperia Z4 Tablet plays in a different league and is also a pioneer in many ways. From now on Sony tablets are part of the company's mobile division, so Sony Mobile is now responsible for their present and future, as well as Xperia smartphones. The device received an LTPS display with 2K resolution (a first for Sony), a Snapdragon 810 chipset, and a microUSB port without a plug (with all protective properties retained). There were also some unique records: the thickness of the tablet is only 6.1 mm, weight - 390 grams for Wi-Fi versions and 395 grams for LTE. This is the thinnest and lightweight tablet with a display diagonal of 10". It is especially pleasant that, while maintaining the screen size, it has become much more compact than its predecessor. Compared to the Xperia Z2 Tablet, the frame of the body has been reduced by 20%, as a result of which the Z4 Tablet has become approximately 1.5 cm shorter and 0.5 cm narrower than the previous model. Compared to the Tablet Z and Z2 Tablet, the build quality has also improved, but the materials have changed. Now there is matte, rough plastic (no soft touch) with metal accents on the frame for greater durability.

Thanks to the new chipset, it was possible to implement the technology fast charging- at least 70% per hour. That is, you can throw the tablet for a few minutes before leaving the house and provide yourself with almost a full day of work. Sony also praises battery life - up to 17 hours of video playback, up to 12 hours in real, non-laboratory conditions. One more important feature for the Z4 Tablet and subsequent devices in this line is an emphasis on the audio capabilities of the devices. The new product received support for Hi-Res Audio, DSEE HX technology (improves the quality of tracks with low bitrates by restoring frequencies), as well as new gadgets: LDAC (for playing high-resolution audio via wireless connection on special headphones) and ANC (automatic distortion compensation and automatic sound optimization for any inserted headphones). The digital noise reduction, familiar to us from the Z2 and Z3 smartphones, has also not gone away.

The tablet works very quickly (no wonder with such a chip and 3 GB random access memory) and also comes with Lollipop out of the box in its tablet interpretation. IN programmatically we can only note support for PS4 Remote Play and the ability to make calls in the LTE version, as well as a largely redesigned Xperia interface Home in accordance with Material Design. Characteristic feature The tablet, like the M4 Aqua smartphone, is the lack of a magnetic mount for charging docks and accessories. It is becoming a thing of the past and will be replaced by new bells and whistles (cases, keyboard docking stations, and so on).

Tablet price for this moment unknown, but it clearly will not be democratic. The market launch is expected in June. Top-end hardware, the clearest screen in the company, new sound capabilities, etc. are worth a lot, and even more so in the current economy. All that's left to do is wait official information By Russian market, holding breath.

What do you think about Sony's new products? Leave your thoughts in the comments and ask questions, we will try to answer them in full reviews!

We admit: the name alone of the new middle-end smartphone from Sony puts us in a bit of a stupor. Think about it: Xperia M4 Aqua - does anything bother you? For the author of this material, just the name of this gadget raises two questions. First: it’s not clear what the letter M in the name means - is it a class higher or lower than smartphones Xperia series T? Second question: many Sony smartphones are protected from dust and moisture, but only the M4 has this feature reflected in its name - why is this done? Is this really the main trump card of the gadget, and it has nothing else to boast about? Yes, I remember that the word Aqua was also present in the name of the special modification of the Xperia M2, but it was necessary there - the original version did not have dust and moisture protection. M4, on the contrary, are all protected by default. Let's try to figure it out.

⇡ Appearance and ergonomics

Testing the M4 Aqua began with a curious incident. The smartphone arrived in our test laboratory at the same time as the flagship Xperia Z3+ and lay in a drawer next to it for some time. When it came time to test, without photos from the Internet we could not tell where the Z3+ was located and where the M4 Aqua was - when turned off, these smartphones are very similar to each other, it is very easy to confuse them.

The differences in size between the Z3+ and M4 Aqua are minimal - the latter's body is just a little smaller, eight grams lighter and 0.4 millimeters thicker. Subjectively speaking, using the Aqua with one hand is a little more convenient than using the Zetka. The fact is that its display diagonal is exactly five inches, and not five and a half, like the older model - it turns out that it is a little easier to reach with your finger to the edges.

There are no hardware keys on the front panel of the smartphone - the buttons here are virtual. Actually, there aren’t too many different elements here at all: in the upper part there is a lens of the front, five-megapixel camera, a slot conversational dynamics and sensitive sensor area. At the bottom there is a mesh covering the microphone.

In terms of ergonomics, the gadget is no different from other modern Sony smartphones- the arrangement of connectors and controls is completely standard for a device from this company. There is a round power button on the right side. Its stroke is somewhat soft - it may not be pressed the first time, but these are trifles and quibbles. Next to it are volume control buttons and a hardware photo key. The latter, it should be noted, is very useful when shooting underwater, when the device does not respond to touches on the display.

Sony Xperia M4 Aqua Dual - SIM card slot

At the same end there are slots for two Nano-SIM cards. They are hidden under a plastic plug. Of course, if you plan to immerse the device in water, the plug must be pressed tightly against the body.

The universal 3.5 mm audio output for connecting a wired headset is located on the top end, and the Micro-USB interface is on the left. It is noteworthy that the latter does not have any plug - the connector itself is waterproof. Sony calls this solution cap-less; it has been used since the Xperia Z3+. There is also a slot for installing a microSD memory card; it is hidden under a flap.

The back panel of the smartphone is covered with plastic, not tempered glass, as it is done in flagship Sony models. The plastic, it should be noted, is quite durable: during testing, the smartphone was often carried in the same pocket with the keys, and there was not a scratch on it. True, the surface of the back and front panels is easily soiled - it quickly becomes covered with “fingers” and other fine dirt, and getting rid of them is not so easy. On the back panel there is a main 13-megapixel camera lens and a single LED flash.

⇡ Protection from dust and moisture

Sony engineers have been protecting the cases of their smartphones from dust and moisture for several years now - this option in itself in the Xperia series device will not surprise us. It is noteworthy that Sony makes not only smartphones, but also tablets waterproof - that is, the company really has a lot of experience in this area, other “mass” mobile phone manufacturers can hardly boast of this. Another thing is that the company’s older, flagship devices usually receive housings protected from dust and moisture. There are, of course, exceptions like the Xperia M2 Aqua, but they are still quite rare. So the M4 Aqua is one of the few mass-produced mid-price smartphones with dust and moisture protection. In a sense, it can be considered unique - in general, it has no competitors.

The smartphone is protected from dust and moisture in accordance with IP65/68 standards, typical for Sony devices. This means that dust cannot get inside the Xperia M4 Aqua at all. Also, the smartphone can be immersed in fresh water to a depth of one meter and keep there for up to half an hour. The manufacturer comments on the security of the smartphone case as follows: “The Xperia M4 Aqua is protected from water and dust, so it is not afraid of heavy rain or washing under the tap (however, remember that all ports and covers must be securely closed). The device must not be completely submerged under water or exposed to sea water, salt water, chlorinated water or liquids such as alcoholic beverages. Incorrect or improper use of the device will void the warranty. The device is assigned protection class IP65/68. additional information see www.sonymobile.com/waterproof. Pay attention to Xperia device There is USB charging port for connecting to other devices that is not covered with a lid. If your smartphone has been exposed to water, charge it only after the USB port is completely dry."

We admit that while testing the device, we swam with it in both chlorinated and sea water - the smartphone passed such tests without problems. It is noteworthy that we did not just immerse the gadget under water, we kept it there for a long time - once the device floated for as much as fifteen minutes. Absolutely all functions of the device worked perfectly after immersion in water. normal mode. Let us note once again that the gadget, of course, does not react in any way to touching the screen under water.

Manufacturer

operating system

A shell pre-installed on portable devices, including a set of tools for managing resources, functions and applications. At the moment, the most common operating systems for modern smartphones and tablets are Apple iOS (only on Apple devices) and Google Android(on devices from most manufacturers). The largest number of applications have been developed for them. The third most popular is Microsoft platform Windows, which, like Android, is not tied to the manufacturer. BlackBerry devices traditionally use their own OS, while others mobile platforms are extremely rare.

SIM card type

In modern mobile devices that support cellular communications Three types of SIM cards are used: module standard size mini-SIM, compact micro-SIM module and the smallest - nano-SIM. All three modules have the same pin arrangement and can be installed in any mobile device that has a SIM card slot. If the dimensions of the slot and SIM card do not match, an adapter is used or the plastic case is cut off. Currently, SIM cards are produced both in the form of a specific type of module and a universal one (Mini or Micro), from which, if necessary, a smaller module is “broken out” using special slots.

OS version as of the start of sales

Android 5.0 Lollipop

GSM is a global standard for digital mobile cellular communications and belongs to second generation networks (1G - analogue cellular communications, 3G - broadband digital cellular communications). Telecom operators around the world use one of 4 frequency bands for GSM: in Europe, Asia, Africa, Australia - 900, 1800 or 1900 MHz, and in America and Canada - 850, 1800 or 1900 MHz. A phone that supports only one of the GSM frequency standards will not function in networks of other standards. Currently, the vast majority of manufactured devices are three- and four-band, thanks to which they operate without problems all over the world.

CPU

Qualcomm Snapdragon 615 MSM8939

CPU frequency

CPU clock speed shows maximum amount simple operations that the processor can perform in one second. The higher the frequency, the higher the speed of the device, but such a comparison is only appropriate for processors of the same line, since, in addition to frequency, there are other parameters that affect performance (its architecture, cache size, etc.).

Number of Cores

Modern processor manufacturing technologies make it possible to place more than one core in one package. The more cores, the higher the performance, however, there are other parameters that affect the power of the processor.

Camera

Main camera

The vast majority of modern smartphones and tablets are equipped with cameras for taking photos and videos. This tool is always at hand, thanks to which you can capture important information or catch interesting point. The quality of the footage can be roughly determined based on the number of megapixels of the built-in camera matrix. However, due to the impossibility of installing full-fledged optics (lens), which plays one of the key roles for getting high-quality image, built-in devices are significantly inferior in characteristics to independent digital cameras.

Autofocus

Automatic focusing of the lens when shooting. On a mobile device with autofocus, you can get more high quality photos: sharper, more detailed.

Front-camera

The number of light-sensitive elements (in millions of pixels - megapixels) that are used to form an image on the camera sensor. How larger number megapixels of the matrix, the higher the image detail. The front camera is more often used as an addition to the main one; its direct purpose is video communication, which does not require high resolution. For photo and video shooting, the rear camera has a higher resolution.

Mobile devices use technology to digitally enlarge the central part of the picture to the size of the entire frame, creating the effect of a camera “zooming in.” The resolution of the resulting image is reduced, which causes a deterioration in the quality of the photograph.

This function is not important, because, even if it is absent, you can enlarge or reduce the required portion of the image using a graphic editor.

Touch screen

Screen type

Today, screens for mobile devices are created using LCD technologies, where liquid crystals are used to backlight the matrix, and AMOLED - an active matrix on organic LEDs. The design of both matrices uses TFT thin-film transistors.

LCD screens can be divided into two groups: TN and IPS.

TN is the oldest manufacturing technology for TFT matrices. Advantages: low price, short pixel response time. Disadvantages: small viewing angles, inability to get perfect black color, as a result, low contrast, problems with correct color rendering. IN modern devices does not apply.

IPS is characterized by wide viewing angles (178 degrees), the ability to correctly display black color, which has a positive effect on brightness, contrast and color reproduction. LCD displays tend to overcompensate for red tones with muted greens, so the images they produce have natural color renditions that are close to standard profile color scheme used in photos and videos.

Separately, it is worth noting the Retina screen, developed by by Apple based IPS matrices. It has such a high pixel density that the human eye is unable to notice that the image consists of them.

"Younger" AMOLED technology has both advantages and disadvantages compared to LCD. Among the undoubted advantages are shorter response times, thinner screens and full viewing angles (180 degrees). Each subpixel of such a matrix has its own backlight, which makes it possible to achieve a wide color gamut, high definition and picture contrast. However, AMOLED's ability to display a wider color gamut often results in oversaturated images and unnatural colors, since the most powerful colors in the subpixels are blue and green. The energy consumption of AMOLED screens directly depends on the brightness of the image: to display black colors, the LEDs do not emit light, and when actively working in bright colors, they gradually “burn out” and power consumption increases significantly. The screen structure consists of several layers (matrix, LEDs, transistors), which makes it possible to produce rounded screens.

Touch screen type

Resistive screens are inexpensive to produce and respond to pressing (not touching) with any object: finger, stylus, credit card. When pressed, the conductive layers are mechanically closed (bending of the top layer) and the coordinates of the pressing point are calculated. Disadvantages: light transmission is no more than 85%, they do not support multiple simultaneous touch points, and they are not able to recognize pressure. They are used in budget models of portable devices, often in e-books.

Capacitive touchscreens are the most expensive to produce due to complex electronics for signal processing. Advantages: recognition of multiple touch points (multi-touch), transparency up to 90%. Such screens are more durable, since the top layer is made of glass. Not susceptible to touch with regular gloves (special gloves are now being produced for capacitive screens) or hard objects. Used in most portable devices - smartphones, tablet computers, laptop touchpads.

Inductive screens respond only to a special stylus and are usually used in graphics tablets(art, children's).

Infrared screens work according to to the following principle: The grid formed by IR rays is interrupted when any object touches the screen. The controller determines the location where the beam was interrupted. They are used more often in e-books.

capacitive

Multi-touch

A technology that allows touch screens to recognize multiple touch points simultaneously. It is especially relevant for providing navigation functions, scaling (moving or spreading fingers), and rotating objects on the screen.

Memory

Built-in memory capacity

Modern portable devices are equipped with drives for storing files and installing applications, implemented in the form of Flash chips. The size of the built-in memory is key value when choosing portable device, especially if it is not equipped with a slot for installing memory cards.

RAM capacity

Used for temporary storage of data. A large amount of RAM allows you to increase the overall system performance and makes it possible to comfortably work in multitasking mode and with resource-intensive applications.

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 choose a telephone. 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.
