Positioning

Microsoft unexpectedly realized that they could not sell smartphones, and Windows Phone was not popular. By the end of 2014, the sales of Smartphones Lumia dropped sharply in all countries of the world, their share in the smartphone market dropped to 3 percent, these are minimal values \u200b\u200bfor the company. The numbers say an obvious thing: devices on Windows Phone on the market are not in demand, their audience is minimal. Inexpensive models use the greatest demand, and in 2015 the company's strategy is to produce as many cheap devices as possible. Not just the most inexpensive smartphonesAs it was in previous years, when the Lumia 520/521 was the backbone of sales and occupied the lion's share of the Windows Phone market, and models in each price segment with an attractive cost. The good undertaking, which, in the theory, could play a role if Android was inside the devices. But as we have already seen, in practice Windows Phone is the brake that exists for the Lumia line sales. And it is impossible to remove it. Can change windows name Phone on just Windows, but reveracted the unsuccessful interface, the mobility of the software and additional programs It is impossible. As well as convince people why they need it. The mass consumer does not enter into a controversy with Windows Phone apologists or employees of the company, it comes more effectively - does not buy their devices.

Model 640 is represented in two horses - the usual 640 with a 5-inch screen and a camera of 8 megapixels, in a glossy case, as well as 640 xL with a 5.7-inch screen, Zeiss chamber for 13 megapixels and a little more battery.

Microsoft fell to the most bottom, as they understand that such models will not have noticeable sales, and it means that you need to create the highest possible number of variations. Not one model with verified characteristics, and a whole set of devices. I'm afraid to navigate in them with an ordinary person will be difficult, the calculation is based on the fact that something is accidental from all this diversity will buy. If earlier in Nokia proceeded from the real needs of the market and did the form that they were trying to create something, now even a hint of it. Release many models, each of which is designed to minimal sales, and due to their number the total circulation will increase. In any case, the general figure of the circulation is so insignificant that it does not deserve consideration. Let's see how many models in the 640 series exists. So, for the usual apparatus it is 640 3G DS (9,990 rubles), 640 LTE (10 990 rubles), 640 LTE DS (10 990 rubles). Already at level russian market It is possible to fail in the planning of the line, so, the version of two SIM cards is exactly the same as the usual version with LTE. Why? The answer lies in the fact that one of them is superfluous and not needed. In the XL version, the same is the usual XL (in Russia there is no), XL DS (14,990 rubles), XL LTE, XL LTE DS. For Russia, only one model of 640 XL was chosen, as others would create confusion and sell them would have to have for the same money.

Who can approach the 640 XL model? This is a person who is looking for a phable, that is, a device with big screen, not very laying in her preferences, ready to sacrifice almost everyone, but to get, as it seems to him profitable proposition. In Microsoft, the load to this device is given a subscription to Office 365 (personal license for one year and one PC, tablet, telephone). From tasty - 60 minutes of calls to city numbers in Skype.

In general, this device is not to extend the number of Windows Phone fans, but rather for those who for some reason are brewed in this environment and believes what did a good choice. Marginal device for a small interlayer of users. Seriously consider it as a competitor to any Android smartphones can not, he has no serious and noticeable advantages.

Design, dimensions, control elements

I like the layouts, my main device is Note 4, and the device from Microsoft is very similar to it in size - 157.9x81.5x9 mm, weight - 171 grams. In the hand, especially male, quite comfortable and is well.

In comparison, C. Samsung Galaxy Note 4.

The housing is made of polycarbonate, it is rough to the touch, very pleasant. Chose a white apparatus, orange Lumia I'm a little tired. On the first day it turned out that the body is not just a brand, everything sticks to it. Paint from jeans (where?), Money lying near, and so on - the case is painted, and then you have to rub it to remove the divorces.

It is good that there are other color solutions - blue, black and orange, they are less susceptible to this misfortune. Although they paint.

On the upper end there is a 3.5 mm connector, on the bottom - the usual microusb connector. On the right side - a paired volume control key, immediately - the on / off button. The output of the speaker is on the rear surface, close to the camera and the LED flash.

Open the device is easily, the housing is drawn over, it's like a cover. The design tested on the set of models is very reliable. Inside you will see the battery, as well as two connectors for Microsim plus a memory card connector.

From the engineering point of view there is no complaints to the device, it is quite good.

Screen

The usual IPS matrix with a diagonal of 5.7 inches, resolution - 1280x720 points (259 dpi), covered Corning Gorilla Glass. For your price segment A full-worthless screen that has no special differences from a variety of models, outstanding characteristics there is no, but the display will suit the majority. Buttons in the apparatus of the apparatus. Say something separately about the screen is impossible - normally and habitual.

Battery

Battery 3000 mAh Li-Ion, work in standby mode - up to 39 days, in conversation mode - up to 23.7 / 31.3 hours (3G / 2G), playing music - up to 102 hours, work in Wi-Fi - up to 13 hours, video - up to 11.7 hours. In real life, two days of work are a completely achievable indicator with a fairly active use of the device, it may be three days. The device is slightly inferior to Lumia 1320 for this parameter, there was a 3500 mAh battery. But in general, everything is fine, the time of work for this model turned out decent and favorably distinguishes the device from classmates.

Communication capabilities

Standard set Protocols - Wi-Fi 802.11 b / g / n, USB 2.0, Bluetooth 4.0 (no support for LE) - full set Standard profiles, WCDMA. As you can see, the device does not boast something special or unusual.

Chipset, memory, performance

A typical solution from Microsoft, inside Snapdragon 400, 4 cores up to 1.2 GHz. The interface works quickly enough, which is also typical for such solutions. The amount of RAM is 1 GB, built-in - 8 GB, memory cards - up to 128 GB. In synthetic tests, these are the results.

Camera

Front-camera Does not very good pictures, despite the fact that it has a resolution of 5 megapixels.

But the main chamber of 13 megapixels with the inscription Zeiss was to please, but since this budget decision was not very good. On the screen, the pictures look well, but as soon as you start to understand what is happening, you see that the white balance lives his life, with pictures with the participation of the sky almost never correctly draw the clouds, often they simply disappear. There are a lot of such "little things", partially the situation corrects the mode of the optimal frame, it takes several pictures. But in general, everything is rather depressing. But Nokia did focus on the cameras, however, almost all key employees that they were engaged in this area, went to work to other companies.

See how this device removes.

Software - Windows Phone 8.1

Phone on Windows Phone 8.1 Update 2. Added to great amount Functions - Now in the "Settings" section there is a division on items (!!!), also separate settings can be reached on main screen. When typing, you can add your text shortcuts for quick input. And this is all for UPDATE 2. I do not get tired to hit the speed with which Microsoft add new features - per hour on a teaspoon compared to this seems to be the first space speed. No, these guys really the fastest on the planet - entered the settings in the menu, although in Windows 10 there is completely different menus! Well done, keep it up.

Smartphones Lumia first appeared on sale in 2011. Development and production of a new brand mobile phones started as a joint project of Finnish brand Nokia and the largest American IT corporation, the main specialization of which is the release of a wide range of user software, including operating systems.

Lumia: Microsoft Windows-Smartphone Series

It is in search of the implementation of your own software product that the company's assets of the Finnish enterprise began to release smartphones with pre-installed Windows Phone. The rebranding series occurred somewhat later, and the word "Nokia" was lost from the name of new models.

Today, a popular Windows-smartphone series is officially called Microsoft Lumia. This name unites in the framework of the catalog of released models at once several generations of various options for the implementation of each of them. One of the last devices of the series is Microsoft Lumia 640 XL, deservedly applying to a place in the premium segment of smartphones.

Appearance and "Stuffing" of the device

This model has a preset Windows Phone 8.1, the work of which is ensured by the CPU QUAlcomm Snapdragon 400. This four-core miracle of the microelectron industry operates at 1.2 gigahertz speed - an indicator is quite sufficient for a comfortable practical use phone A distinctive feature Microsoft Lyuma 640 XL They are wide dimensions. Length x Width x Height \u003d 157.9 x 81.5 x 9 mm. Such dimensions are necessary because the device is equipped with a 5.7-inch screen. The permission of IPS -matrum with such a diagonal is 1280 per 720 pixels.

Design and design

Structurally 640 and 640xl are made in the company Nokievsky style - "Corpus-box", from which the body of the device is retrieved by pressing the corner. 640xl is made in a matte unpacked case. 640 is made in a "glass case" - from two-layer plastic. At the bottom of the color plastic, and outside the thin layer of transparent.

Lumia 640 XL:

Winphon-Ami wonders remember that earlier most lumies had excessive large frames around the display. Especially top and bottom in portrait orientation. But 640 and 640xl with the balance of the display area and the framework everything is fine! Lumia 640 the upper and lower frames are finally the same and very small, and XL also has a lower very tiny, less top! It used to be the opposite, and it looked disharmoniously.

In both devices, the control key is on-screen. They can be removed manually so that they do not reduce the display area. An interesting nuance is removed and returned to the screen. They are one and the same movement - a finger on the screen from the bottom up, which at first somewhat strains. It would seem to be logical - to activate the button "pulling out" the top of it from below, but to remove - on the contrary, the movement from top to bottom ...

Microsoft Lumia 640 and 640 XL :: Overview :: Display

In both devices, juicy IPS screens with the same HD resolution of 1280x720, with awakening double tap and glowing hours.

With the same resolution on Lumia 640 less diagonal, respectively, less than the size of a single pixel, so that the image is theoretically "call". However, the difference in diagonals is small and the differences are not noticeable. A much more prominent difference in brightness and corners of the review - screens for the "younger and older brothers" were clearly cut from one "IPS-sheet" - the display 640 XL noticeably brighter 640th, XL has more viewing angles. Wherein increased brightness The screen 640 XL makes the color level somewhat "grooved", as with an overposposed photo, while the 640th color remains more natural.

Microsoft Lumia 640 and 640 XL :: Overview :: Camera

In many large-sized wide lumines, I have repeatedly encountered very weak cameras. In this case, the other way is, and somehow closer to mass logic: Lumia 640 is equipped with an average 8-megapixel camera, and the older brother XL is 13-megapixel, which even visually looks solid, its module protrudes from the holloch case, giving the device to the device . However, in fact, everything turned out to be at all right!

Amazingly, but the cameras are almost the same, despite the essential difference in megapixels, and 640-whales, in addition, it also works and noticeably fade, that I am surprised to find out, removing the vigorous rat in the pet store! Ensure this is easy - the same snapshots were specifically made on both devices.

Large segments from frames of a 13-megapixel camera look, if not worse, then certainly not better than 8 megapixel ... The question arises - how to interpret the result? This Lumia 640 removes better than it should, or Lumia 640 XL - worse than you wait for it? It is definitely difficult to say ... with similar processors, process the flow of data from an 8-megapixel matrix is \u200b\u200bdefinitely easier than with a 13 megapixel - this is probably worth explaining a large smastality of the younger model. And personally, I (subjectively, of course) would say that it was 640th removes better than it would be worthwhile. And 640 XL may have other, and not the best image processing algorithms and optics.

Microsoft Lumia 640 and 640 XL :: Overview :: Performance and nutrition

In devices, oddly enough, different processors are installed, although the common name for two smartphones implies, logic, a common chip ...

Lumia 640 - Qualcomm Snapdragon 400 MSM8926
Lumia 640XL - Qualcomm Snapdragon 400 MSM8226

However, the difference in terms of performance is actually absent. The Lumia 640 processor is announced in 2014 and supports LTE, and the Lumia 640XL processor is its predecessor, announced in 2013 and does not support LTE. Otherwise - these are chips medium category Power, whose characteristics are completely coincided. These same processors are also set in other smartphones with comparable price and power category - LG G2 mini, Sony Xperia. M2, etc. In Antutu Benchmarck, both gadgets are gaining the same scores - the difference in the level of error. With such points in windows Environment Phone smartphones work smartly and smoothly, although, of course, productivity is far from the most outstanding. 640th scored 12.270 "Parrots", and 640 XL - 12.067.

The devices are installed, of course, different batteries: in 640th 2500 mAh, in 640 xL - 3000 mAh. We will conduct an easy and visual test, which I traditionally use to assess the battery efficiency - I charge the battery 100%, reboot the device to clear the memory from the clogging programs, turn off everything wireless interfaces, Besides cellular communication, We put on the maximum brightness of the screen and volume. Run a movie in AVI format, lasting 1 hour 23 minutes and a weighing of 1.45 GB. After the film is completed, we look at the battery balance:

In principle, with certain efforts with both smartphones, it is quite possible to hold out two days away from the outlet, but, of course, it will be easier with XL.

At the time of writing, the Lumia 640 review cost about 12,000 rubles, 640 xL - about 15,000 rubles. Against this background, Lumia 640 looks like a more balanced apparatus, unless the 5.7-inch screen is not decisive for you to watch movies and more comfortable web surfing. For with the same performance due to actually identical processors and rAM, the difference between two smartphones can be the most objective:
