Lumia 540 Dual SIM Description. Information on other important connection technologies supported by the device

Many advanced android users The devices during the need to change the smartphone are often wondering if it is worth considering the device that does not work on the familiar system. Most likely, it is worth. After all, in this way, you increase your experience using electronics. But to buy a device from Microsoft in return to his old android, you need to decide on some factors. It is for these purposes to present you a review regarding the cheap Microsoft Lumia 540 Dual SIM device.

Equipment

Microsoft is not too puzzled in plans to put in the box to the end buyer. therefore basic set Accessories are a fairly simple - charger, user manual, a removable battery for 2200 mAh and, of course, the device itself. I want to immediately warn that USB cable Included. You will have to either buy it, or you have to use the wires you have.

Appearance

If you do not focus on the details, the Lumia 540 Dual SIM statefend is very similar to other Microsoft smartphones, in particular, on. The device externally resembles a brick, and maybe even the floor tile for decorating. Officially, only one color option is available in Russia - black. But this problem will help to solve the purchase of additional interchangeable panels to diversify your life with bright colors. On the back cover plastic terribly brand, with the use of too many prints. Nevertheless, they easily disappear when rubbing palm. And now we run through all sides of the gadget.

On the front panel of the device, we can see the display with a diagonal of 5 ", resolution of 1280x720 pixels. On the top of the front there are light sensors and approximations, they are difficult to notice with a naked eye, as they merge with the case.

There is also a spoken speaker here (some complain about the volume, but I did not notice anything bad, the interlocutor is heard perfectly), the inscription Microsoft and the frontal five megapixel chamber.
On the bottom of the front panel, we can only see the conversational microphone, since the control buttons at the device are appropriate.

From above on the back, you can see the main camera with a LED flash, and below the speaker for media files and programs.

On the other hand there is nothing, smooth panel. On the top face, as in many other devices, there is a jack for connecting headphones or a headset 3.5 mm. As you read above, there are no headphones in the kit, so you need to take care of it in advance.

On the bottom, we can watch the cable connector charger or wires micro USB. (I repeat that it is not included).

On this end with the design. Go to the characteristics of the display.

Display

The device has a good IPS screen with a diagonal of 5 inches. The resolution of the display was 1280x720 points, above this processor simply does not support. I personally pleased the viewing angles, the picture almost (emphasizes, practically) always remained color and bright. Look at the photo below.

Thanks to the brightness of the display, you can work with a smartphone even on a sunny day on the street. For such a price, the manufacturer decided not to protect the model glass Gorilla Glass, so when handling it, be careful.
Thanks to the built-in illumination sensor, the machine can automatically adjust the display brightness level.

Iron

The device works on a bit outdated (but relevant to windows systems Phone) SNAPDRAGON 200 four-core processor, which operates at a maximum frequency of 1.2 GHz. Module random access memory is 1 GB. Despite this, compare the backward processor with Android devices It is impossible, since even heavy games (working on WP) speak perfectly to all your requirements (tested asphalt 8), I did not notice seriously.
Built-in flash memory takes 8 GB, which is enough to install a simple software. The manufacturer allowed us to increase the size of the memory using MicroSD cards.

Battery

The device was at his disposal a standard battery capacity of 2200 mAh, which according to the manufacturer, will allow you to actively use your device for 5 hours. Chapter is emphasized that in the listening mode, the gadget is able to work 81 hours. Members of this device declare that in fact the gadget lives for about one day with moderate use and 2 hours in WiFi mode. From this we can conclude that the autonomy of the smartphone corresponds to budget characteristics. The test for the duration of work from Treshboks could not have managed, the browser did not understand what they want from him.

Cameras

Some special attention does not deserve the main chamber. We have the usual 8 MP sensor that allows you to shoot high-quality photos with good lighting. For shooting at night, a LED flash is provided. Autofocus works fast, but not always correct. The possibility of shooting video is limited to the resolution of 848x480. See examples of pictures on the main chamber below.

The front camera received a 5 MP sensor that allows you to take decent selfie. And for a better effect, Microsoft equipped the gadget by the Lumia Selfie branded app.

Operating system

This unit works on an improved version. Windows Phone 8.1, namely thanks to the superstructures of the Lumia Denim system. Here you see the standard for the tile and columns system, everything moves into a pleasant eye of animations. Download any applications you can through the built-in windows Store Store. Soon can be updated to Windows 10.

RESULTS

At the moment, Microsoft has no clear flagships and budgetary devices, so it is difficult to attribute the device to any category. This is just another smartphone that has quite decent characteristics and functions. Of the minuses, I will note the lack of Gorilla Glass glass and video recording in the maximum resolution of 848x480 pixels. If you go to Windows Phone with Android, then this device will be the most appropriate. At the time of writing a review, the device costs 10390 rubles.

Microsoft has released an excellent line inexpensive smartphones. Her name is Lumia. A series of mobile devices quickly gained popularity. The indisputable advantages of users consider a low price, windows platform Phone, bright and original design, high-quality assembly. And this is not all that they could attract the buyer.

For a detailed study, choose the Microsoft Lumia 540 smartphone. Unfortunately, the "state employee" label implies the presence of restrictions. For example, using this model is unlikely to be played in modern 3D toys, make delightful pictures. However, the manufacturer did not praise on the services of designers. They created a truly positive phone. Also, buyers also attracts a screen with pretty good characteristics and the ability to work immediately with two SIM cards of different mobile operators. And of course, you should not underestimate the possibilities of Windows Phone. Looking in advance, we inform the readers that the device is based on the operating system version 8.1. However, everyone can update everything to the ultra-modern "dozens".

Equipment

Lumia 540 comes on store counter in a beautiful cardboard box. Packaging looks presentable. On the front panel presented photo of a smartphone close-up. The phone on it is located with a slope of 30 °. The picture has a view of both front and rear. The logo with the name of the company is printed in the upper left corner, and the name of the model itself can be seen on the opposite side. The lower panel is quite informative. It presented the most important characteristics on it: screen size, capabilities and processor model and so on. Of course, there is information about operating system. Here is also a photo of the gadget. There is a full model name and package.

The box itself opens by the method of drawer. It contains a rather modest set. It consists of a battery, documentation, power adapter and data cable. It makes no sense to expect more from the "state employee". The set of delivery is usually standard for all gadgets.

Design

At first glance on Lumia 540, you can consider branded design traits. Case - rectangular. It looks somewhat rude and strictly, however, the smoothed edges on the sides and rounded corners soften the overall concept. Feel the disadvantage in the variety of color solutions will not work, because on sale you can find not only classic options (white and black), but also bright youth - blue and orange.

Now it is worth talking about the dimensions of the phone. It is difficult to call it small and easy. The reason for this was a pretty weighty mass, which was 152 grams. Thickness as for modern smartphones, Standard - 8.6 mm. The width of the housing in 73.7 mm is perfectly combined with a height of 144 mm.

As for ergonomics, Lumia 540 DUAL gets only a laudatory reviews. Most owners claim to use the phone convenient and easy. However, when control, you will have to use two hands, in order not to accidentally raise. The main element of the front panel is big touch screen. It is framed by a black frame. On the sides it is quite thin, it is expanding only at the top and bottom. The front chamber lens, sensors, microphone and dynamics hole are also displayed on the front panel. He is decorated with the phone name of the company, which is applied with white, so on a black background perfectly stands out.

The back cover of Microsoft Lumia 540 is decorated with minimalism features. It can only be seen on it, speaker, logo and, of course, basic optics. To locate the connectors, the manufacturer selected the top (for headphones) and the lower (for connecting the data cable) ends. Mechanical keys (Locking and volume control) are on the right side face.

Screen

Not one advantage has Lumia 540, but the main thing is, undoubtedly, the screen. Developers installed a 5-inch display. It displays information with a resolution (1280 × 720 Px), which corresponds to HD quality. The basis is based on the IPS matrix. Already such characteristics make it possible to judge the quality. According to the owners, it is impeccable.

Describing this smartphone, it is impossible to explore another innovative technology. It is called ClearBlack. Developed by the Finnish company Nokia. The main goal for which this technology is used is to increase the quality of the image in direct sunlight. For this, the developers applied special polarization filters. They are installed between the display and the screen glass. Many users did not like the fact that the manufacturer refused to protect measures without applying the modern Corning Gorilla Glass coating.

Camera

Smartphone 540 Lumia manufactured by Microsoft is equipped with two cameras. The resolution of both, as for the "state employee", excellent. To begin with, we will pay the attention of the front. It is based on a 5 megapixel sensor. The quality of the pictures is good, as optics are equipped with a wide-angle lens. For lovers of Selfie, this model is just a find. With the help of a front camera, you can remove good videos. The maximum resolution with which the record will be played is 480 p. The speed is limited to 30 frames per second.

The same features in video mode is equipped with the main chamber. However, it uses an 8 meters matrix. This, of course, is not the highest permission from possible, but it will be enough for a high-quality snapshot. If necessary, increase the object or closer it is provided by a 2-fold zoom. Unfortunately, users noticed the shortcomings in the work of the optics - noise and distortion of chroma. Most often, they are manifested in the pictures made in bad lighting.

Lumia 540: Battery Characteristics and Offline Terms

The battery plays an important role in drawing up a gadget. After all, the duration of work without recharging will depend on it. In the 540th model, the developers set lithium-ion battery Removable type. Its potential is 2200 mAh. It will take 2 hours to restore the resource. According to the stated characteristics, the following indicators can be distinguished:

• the conversation time will be about 15 hours, subject to connection to 3G;
• work on the Internet via Wi-Fi - 10 hours;
• view video - 7 hours;
• listening to music tracks - 81 hours when played through headphones;
• standby mode - 24 days (maximum).

The owners say that with an average load, the Lumia 540 telephone is capable of functioning 1-2 days. When the performance is reduced, you can extend autonomy time up to 4 days.

Performance

The hardware "filling" is the only thing that can be considered a weak side of this model. The poor processor Qualcomm Snapdragon 200 was the reason for this.
