  • Smartphone BQ BQS-5520 Mercury;
  • Charger;
  • USB-MicroUSB cable;

Charger provides the output 5V and 1.5A. Charges smartphone rather quickly, although 2A would be faster. It is also worth noting the presence of a protective film on the screen, which is a photo of the entire set is missing, but was originally glued to the screen of the smartphone.


The smartphone is quite simple, without any design decisions conspicuous. A large bar with a full glass front. No sharp corners: the smartphone the most rounded and streamlined. The boxes around the average width of the screen, but at the expense of glass 2,5D they look even longer than it actually is. As soon as the screen is located under the film, the presence oleophobic coating could not be verified, but it is likely there is no or very modest quality – can be seen on the open areas of the screen.Incidentally, the film stuck. Since glass has a roundness of the edges (2,5D effect), stick the tape it is not so simple, it is simply not adjacent the perimeter. The manufacturer decided this problem in a simple way: take the film to 3 mm smaller than the screen surface. It looks not very nice, and the finger clinging to the edge of the film, but it fits the film perfectly.

Now, about the size of the body. The smartphone is not compact, as evidenced diagonal of its screen. Body dimensions is 154 x 78 x 9 mm and weighs 155 g If you are used to large devices with a screen of 5.5 inches, and the BQ BQS-5520 Mercury is easy to manage, but if used in addition to 4.5 or 5 inch smartphone you do not use, then this device will seem larger. But as they say, a matter of habit, after a few days of use, you will appreciate the large screen.


The back cover is removable. It is made of matte gray plastic, without any pattern. The surface is smooth. Particularly slippery body BQ BQS-5520 Mercury can not be called, in his hand he is pretty confident. In addition, the material turned out to be, and is not easily soiled, if it is still small and fingerprints, they are easily erased on any fabric. As for the scratches, then over time the use of plastic will not scratch, but there are reasons to believe that by careless handling will scratch quickly. So, if you want to avoid them, it is necessary to take care of the case.

Above the screen are concentrated all the main elements of the front side. There is a front camera with a resolution of 8 megapixels, next to which there is a LED flash, the camera is located on the left of the earpiece, light sensor and proximity, as well as LED indicator events. Under the screen there is nothing, and virtual navigation buttons are located directly on the smartphone screen.

On the rear surface is the main camera with a resolution of 13 megapixels, which is quite a lot for this price segment. Also, there is a LED flash and a fingerprint scanner. Yes, yes, your smartphone for 9000 rubles, and it is this – great news.

Regarding the location of the fingerprint scanner can argue for a long time: someone likes that he is back, someone recognizes the scanner only on the front panel below the screen. In our case it is located on the rear panel. Works scanner is not very fast, unlocking takes about a second, but that’s exactly envy, even many top models. Of the 10 attempts to correct the exhaust 10 – an excellent result. All sensor operation is configured through the standard Android menu, it is done very simply and quickly.

On perimeter of the body passes plastic trim, painted in metallic color. Attribute almost all state employees. On the left side there are no elements on the right – turn the volume and adjustment knob.

At the lower end of the microphone and the main speaker, which are hidden under the symmetrical perforated grille. Top MicroUSB port and a headphone jack.

As already mentioned, the back cover is removable, it is easy to dismantle, latch hold is not very hard. The main part of the lid occupies a capacious battery, and card slots on it.


BQ BQS-5520 Mercury supports two SIM-cards micro-SIM format, which operate in a mode Dual Stand Dual Standby (DSDS). When talking to one of the rooms of the second will be unavailable. This scheme is used in almost all smartphones, except for devices with two radios, but such devices do not meet often. Immediately there is a slot for a memory card that is supported by the amount – up to 128 GB.

BQ BQS-5520 Mercury: SCREEN

The main “chip” of the screen – this is his 2,5D glass. More recently, this technology was used only in high-end smartphones, but now the miter smoothly into the glass and in the budget segment. It looks so much more effective coverage and more enjoyable than an ordinary flat glass. In addition to the BQ BQS-5520 Mercury we IPS-matrix, the size of 5.5 inches, a resolution of 1280×720 pixels, which gives a density of 267 ppi. It is not so much, but for daily use is sufficient. The individual pixels are visible only on closer examination. By the very quality of the pictures we have no complaints, the screen shows the most natural colors, brightness and saturation in short supply. To set color profiles is available preinstalled MiraVision application. Another useful functionality is the image mode setting, which changes the color temperature in real time. It is a useful feature for those who like to read in the dark.


BQ BQS-5520 Mercury runs under Android 6.0 Marshmallow system. Changes compared to the classic interface is practically no, the manufacturer has added a few applications and services. In particular, the application was originally installed from Yandex, multiple applications from the online stores as well as tags from a few games that you can quickly download.


It is worth noting that the system is updated “over the air”, for which there is a special application. At the time of this writing, the smartphone has the latest firmware to date. two SIM-cards management standard: you can set the default map for different actions (calls, sms, internet), or choose a card at each activity. There HotKnot function. It is not new, but is rarely used. It is a function of the fact that two smartphones with capacitive screens can exchange information at the touch of each other’s screens.


Responsible for the performance SoC Mediatek MT6737, though CPU-Z persistently says that 6735. The platform has a quad-core ARM Cortex-A53 with a frequency of 1.3 GHz operation. Responsible for the graphics accelerator Mali-T720 MP2. It is not bad for a smartphone in this price range.

Next, evaluate the performance of the platform in several popular tests. As expected, no exorbitant figures here we saw a modest performance, which, at the same time, will be sufficient for most everyday tasks.

The graphics core also shows the average performance. The simpler games can easily be played on high settings and do not feel any subsidence fps. For example, World of Tanks: Blitz works fine. But the more resource-intensive games like Asphalt 8, go a little slower, noticeable freezes. Thus, BQ BQS-5520 Mercury can be used as a gaming smartphone, but you need to be prepared that in complex games will drawdown frame rate.

Next, check the compatibility of platforms with various video files. The indicator is not perfect: not to reproduce by sizes larger than has been processed correctly. But it must be said that most of the error revealed 2K and 4K video.

As for ordinary tasks, then there is no problem. The interface is fast opening and switching between applications takes place with the minimum of delay. Internet surfing through Google Chrome comfort, amount of RAM and performance allow you to open more than five tabs at the same time. In general, the impression of performance in everyday use are good.


The smartphone works with all popular communication networks, including the 4G (LTE). The quality of the reception there is no question. This concerns both the 2G / 3G, or LTE. In areas of good coverage smartphone catches network confidently, communication interruptions no internet is stable with good speed. Naturally, there are Wi-Fi, it runs at 2.4 GHz. Admission is also confident, 5 meters from the router the signal is almost the maximum, equal to the tariff Internet speed.

Pleasantly surprised navigation. Supports and GPS, and GLONASS. Search satellites “cold start” takes less than a minute, the location accuracy is high. As a navigator, this smartphone has shown himself perfectly.

BQ BQS-5520 Mercury: CAMERA

The main smartphone camera has a resolution of 13 megapixels, front – 8 megapixels. It would seem that we should expect a very high-quality photos, but they turn out not so perfect practice. When sunlight detail and color-tolerant, but it becomes much worse under indoor light. In general, the masterpieces on BQ BQS-5520 Mercury is not removed, but the documents to photograph or make a few photos on the street is possible.

BQ BQS-5520 Mercury: AUTONOMY

Lithium polymer battery capacity of 3650 mAh provides a decent autonomy BQ BQS-5520 Mercury. In the PCMark test battery, we got the result 6:00 54 minutes, it took so much discharge from 100% to 20% while the Wi-Fi and a maximum brightness of the screen. Battery discharge is the most evenly, without jerks and failures. In everyday use the smart phone easily live for two days on a single charge.


BQ BQS-5520 Mercury, definitely worth the money. The smartphone has turned out quite balanced with a large set of pluses and a few minuses. The obvious advantages can be attributed excellent autonomy, the LTE support, a “clean” system and good design, which has been achieved at the expense of the popular right now 2,5D glass. Of the minuses, perhaps, only the low gaming performance and modest camera.

It is impossible not to mention the price: smartphone sells for 8990 rubles, though you can find much cheaper. For the money it is – a very worthy choice.
