Contents of delivery

Micromax Canvas Juice A1 comes in a fairly large flat square box with a hard cardboard dust jacket. Packaging different smartphones companies are distinguished by this dust jacket, on which all designations, logos and specifications are applied, and the inside remains absolutely clean and identical in all cases.

The scope of delivery consists of a connecting cable, a powerful network adapter with output current and voltage 2 A 5 V, wired headset with in-ear type rubber pads, protective film on the screen and paper instructions in Russian.

Appearance and usability

For the external design of their mobile novelties in the new season, Micromax artists chose a single and rather peculiar design. It is slightly rough, uncomplicated, a kind of industrial type of design, where straightforward practicality prevails over the fashion component and where smooth metal is used in combination with rubberized plastic.

The case as a whole is not metal, for the most part it consists of plastic, only the central part of the back cover is made of real metal: it is a thin plate soldered into a plastic frame. All sidewalls, end parts, as well as the upper and lower rear inserts are made of plastic.

A little metal is added here rather for decoration, since from a practical point of view, any parts of the case will wear out and break over time - the ends, edges, even the front glass - but not the middle of the back side. Yes, and upon impact, this plate, soldered into plastic, will rather fall off by itself than play any protective role, since it has nothing to do with the rigidity contour.

The device is quite thick and heavy, the reason for this is a very voluminous accumulator battery at 4000 mAh, so the increased weight here is generally justified. The plastic sidewalls have a ribbed texture, so the smartphone does not slip at all in the hands. We can't call the body easily visible either, fingerprints here can be seen only on the front glass.

The dimensions of this five-inch device can not be called large, and thanks to the thick body with side rounding of the back cover, the case fits securely and comfortably in your hand. However, for a trouser pocket, its mass of almost 180 grams is still quite noticeable.

In order to get to the card slots, you need to remove back cover. There is no special protrusion for engagement, you will have to rest against the cutout for the Micro-USB connector. The cover can be removed quite easily, there are no problems with this, but it is also surprisingly securely held on its plastic latches, the body as a whole is solid and strong, there is no backlash or squeaks when compressed.

Connectors for all three cards are quickly and conveniently accessible, and it's easy to insert cards in adapters into them, but here they may be needed, since both slots are designed for the outdated Micro-SIM format. One of the connectors is made in an old-fashioned version with a cover that opens upwards, pressing a SIM card, and the other two - for the second SIM card and memory card - are assembled in a sandwich one above the other. All three slots are available simultaneously and are completely independent of each other.

It is curious that although you do not need to remove the battery to access all three connectors, including the memory card, hot-swapping is still not supported here. The device will not react in any way to any of the inserted cards until you reboot the device yourself. This is a rather rare option, especially considering that the battery is not removed here in principle.

The camera module does not protrude beyond the surface, and thanks to the almost flat back wall, the smartphone does not sway when touching the screen, it lies steadily on the table. The flash next to the camera is single-segment, its brightness level can be described as below average.

The main speaker is brought here, on the back side of the case, and this, of course, is not good, since the sound of the device lying with the screen up is noticeably muffled.

The side buttons are installed on the right side, the keys are large, stick out to a sufficient height, have a rather hard move and a distinct response. It is quite possible to get used to a little excessive rigidity of pressing.

The front panel is covered with flat glass without sloping edges. At the top there is a light sensor, a camera without a flash, but, unfortunately, there is no LED event indicator. There is also no backlight at the bottom, since there are no hardware buttons there.

Interface connectors are standardly placed on the ends: the top one is given over to a 3.5 mm headphone output.

At the bottom end asymmetrically, closer to one of the edges, there is a hole for the Micro-USB connector, it supports the connection of external devices in USB mode OTG.

Micromax Canvas Juice A1 is available in two color options: gray with a black side rim and black front panel, as well as gold, in which the front panel is golden, but the side rim is also black.

Screen

The Micromax Canvas Juice A1 features a 62x110mm On-cell IPS touch display with a 5-inch diagonal protected by a flat protective glass without sides and sloping edges. The screen resolution is 1280×720, the dot density is about 294 ppi. The frame around the screen cannot be called narrow: on the sides it is a little less than 5 mm, and on the bottom - all 18 mm.

Display brightness can be adjusted manually or set automatic settings based on the operation of the ambient light sensor. The AnTuTu test diagnoses support for 5 simultaneous multitouch touches. Additional ways activation of the display using a double click or other gestures is not provided.

A detailed examination using measuring instruments was carried out by the editor of the sections "Monitors" and "Projectors and TV" Alexey Kudryavtsev. Here is his expert opinion on the screen of the test sample.

The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are better than those of the Google Nexus 7 (2013) screen (below is just Nexus 7). For clarity, here is a photo in which a white surface is reflected in the off screens (on the left is Nexus 7, on the right is Micromax Canvas Juice A1, then they can be distinguished by size):

The screen of Micromax Canvas Juice A1 is darker (brightness in photos is 104 versus 114 for Nexus 7). The ghosting of reflected objects in the Micromax Canvas Juice A1 screen is weak, which indicates that there is no air gap between the screen layers (more specifically, between the outer glass and the surface of the LCD matrix) (OGS type screen - One Glass Solution). Due to the smaller number of borders (glass/air type) with very different refractive indices, such screens look better in conditions of intense external illumination, but their repair in case of cracked external glass is much more expensive, since the entire screen has to be changed. On the outer surface of the screen, there is a special oleophobic (grease-repellent) coating, which is noticeably worse in efficiency than the Nexus 7, but still fingerprints are removed more easily and appear at a slower rate than in the case of ordinary glass.

With manual brightness control and with a white field displayed in full screen, the maximum brightness value was about 420 cd/m², the minimum was 30 cd/m². The maximum brightness is not very high, but given the excellent anti-glare properties, on a sunny day outdoors on this screen you can see something. In complete darkness, the brightness can be reduced to a comfortable value. In the presence of automatic brightness control by light sensor (it is located to the left of the front speaker slot). In automatic mode, when the ambient light conditions change, the screen brightness both increases and decreases. This function depends on the position of the brightness slider. If it is at 100%, then in complete darkness the auto-brightness function reduces the brightness to 150 cd / m² (very bright), in an artificially lit office (about 550 lux) it sets it to 420 cd / m² (too high), in a very bright environment ( corresponds to lighting on a clear day outdoors, but without direct sunlight - 20,000 lux or a little more) the brightness increases to the same 420 cd / m² (to the maximum - that's right); if the adjustment is about 50%, then the values ​​​​are as follows: 30, 420 and 420 cd / m² (the average value is again too high), the regulator at 0% is 30, 420 and 420 cd / m² (all the same). It turns out that the auto-brightness function does not work quite adequately. At any brightness level, there is no significant backlight modulation, so there is no screen flicker.

This smartphone uses an IPS type matrix. In the micrograph, you can see the subpixel structure typical of IPS:

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 at large deviations of the gaze from the perpendicular to the screen and without inverting shades. For comparison, here are photos in which the same images are displayed on the Micromax Canvas Juice A1 and Nexus 7 screens, while the screen brightness is initially set to about 200 cd / m², and the color balance on the camera is forcibly switched to 6500 K.

White field perpendicular to the screens:

Note the good uniformity of brightness and color tone of the white field.

And a test picture:

Colors on the Micromax Canvas Juice A1 screen have a natural saturation, the color balance of the Nexus 7 and the tested screen differs markedly.

Now at an angle of about 45 degrees to the plane and to the side of the screen:

It can be seen that the colors did not change much on both screens, but on the Micromax Canvas Juice A1, the contrast decreased to a greater extent due to the strong whitening of blacks and the decrease in image brightness.

And the white box:

The brightness at an angle of the screens has decreased (at least 5 times, based on the difference in shutter speed), but the Micromax Canvas Juice A1 screen is noticeably darker. The black field, when deviated diagonally, is highlighted strongly and acquires a reddish or red-violet hue. The photos below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is the same!):

And from another angle:

When viewed perpendicularly, the uniformity of the black field is poor:

Contrast (approximately in the center of the screen) is high - about 1000:1. The response time for the black-white-black transition is 20 ms (10 ms on + 10 ms off). The transition between grayscale 25% and 75% (according to the numerical value of the color) and back in total takes 38 ms. The gamma curve constructed from 32 points with an equal interval according to the numerical value of the shade of gray did not reveal a blockage either in the highlights or in the shadows. The exponent of the approximating power function is 2.18, which is close to the standard value of 2.2. In this case, the real gamma curve slightly deviates from the power dependence:

We did not find the presence of dynamic adjustment of the backlight brightness in accordance with the nature of the displayed image, which is very good.

Color gamut close to sRGB:

The spectra show that the matrix filters moderately mix the components to each other:

As a result, the colors have a natural saturation. The balance of shades on the gray scale is acceptable, as Colour temperature significantly higher than the standard 6500 K, but the deviation from the black body spectrum (ΔE) is less than 10, which is considered an acceptable indicator for a consumer device. At the same time, the color temperature and ΔE change little from shade to shade - this has a positive effect on the visual assessment of color balance. (The darkest areas of the gray scale can be ignored, since the color balance does not matter much there, and the measurement error of color characteristics at low brightness is large.)

To summarize: the screen has a fairly high maximum brightness and has excellent anti-glare properties, so the device can somehow be used outdoors even on a sunny summer day. For conditions of complete darkness, it is possible to set a comfortable level of brightness. The mode with automatic brightness adjustment is present, but it does not work well. The advantages of the screen include the absence of an air gap in the layers of the screen and flicker, high contrast, as well as a color gamut close to sRGB and an acceptable color balance. Among the significant shortcomings, we rank the poor uniformity of the black field and the low stability of black to the deviation of the gaze from the perpendicular to the screen plane. Given the importance of the characteristics for this particular class of devices, the screen quality is relatively high.

Camera

The front camera of the Micromax Canvas Juice A1 received a module with a resolution of 2 megapixels and a lens with an aperture of f / 2.8 without autofocus and its own flash. The shooting quality is rather modest even for the level of a selfie: with such a low level of detail, other characteristics will not play a serious role.

The main camera has a module with a resolution of 8 megapixels and a lens with an aperture of f / 2.2 (for some reason, the official specifications on the Russian site indicate a resolution of 5 megapixels). Autofocus is quite fast, the flash is not very bright, there is no stabilization function. The settings menu here is non-standard, it is much more convenient than the original one from the Android interface, visual and very easy to use. The menu structure is concise: a vertical list pops up on the left with the main sections, when you click on each of them, a second scroll expands on the right with options related to this function. Handy, but the camera has a strange "stickiness" when it continues to take 6 MP (2448x2448) square shots, even if the maximum resolution of 8 MP (2448x3264) is selected in the menu at that moment. As a result, only a complete reset of the device to the factory settings helped us, after which the camera began to behave adequately.

There are not many manual settings in the menu, but everything you need is available. You can manually set exposure, ISO (up to ISO 1600), white balance, shutter speed, select additional modes and color effects, there is HDR. There were no such familiar functions as face detection, smiles and the ability to shoot by gesture. It is impossible to transfer control of camera settings to third-party applications using the Camera2 API, and there is also no possibility of recording pictures in RAW.

The camera can shoot video at a maximum resolution of only 720p, there are no shooting modes at 60 fps, not only 4K, but even Full HD. There is also no stabilization function. The video camera shoots accordingly: miracles do not happen, and it is impossible to achieve good detail from a resolution of 720p. The image is loose, but bright and smooth, without noticeable artifacts, with natural color reproduction. When recording audio in a noisy street, the familiar distortions of echoes and gurgling sounds may appear. With a less noisy sound background, distortion does not appear. Nothing is officially said about the presence of a noise reduction system in this smartphone.

Good sharpness across the field of the frame and according to the plans.

Good detail in the background.

The camera does a good job with shadows.

The immediate plans worked out well.

The camera copes with macro photography.

There are small areas of blur in the corners.

The camera turned out pretty good. The optics give decent sharpness across the field of the frame and according to the plans, and the software processing does not spoil the details, even small ones, although they are noticeable in places. As a result, the camera can be used for documentary shooting, and sometimes for undemanding art.

Telephone part and communications

The communication capabilities are as follows: the smartphone can work in 4G networks thanks to the Snapdragon X5 LTE modem, which allows you to receive data at speeds up to 150 Mbps and give up to 50 Mbps (LTE Cat.4). The device operates in all three most common LTE FDD bands in Russia. At the same time, only one Wi-Fi band (2.4 GHz) is supported and there is no NFC. All wireless modules, including Wi-Fi, behave quite confidently, no problems with registration in networks, unexpected loss of signal, and the like were noticed.

The navigation module, thanks to the Qualcomm platform, supports all three satellite systems - GPS, Glonass and BeiDou. The module is slow, the first satellites are detected during a cold start for more than a minute. Magnetic field sensor, on the basis of which a digital compass usually functions navigation programs, the smartphone, unfortunately, was not equipped. Micromax Canvas Juice A1 is not rich in sensors at all: there are only light and proximity sensors and an accelerometer.

The phone app supports Smart Dial, while dialing telephone number immediately carried out and the search for the first letters in the contacts. IN phone book there are only regular capabilities contact display settings. There is no built-in blacklist, but the function automatic recording telephone conversations with the line is present. In conversational dynamics, the sound is muffled, there is a slight effect, as if the interlocutor is “speaking into the pipe”, but in general, a familiar voice remains recognizable. The vibrating alert unexpectedly turned out to be above average in strength, it is quite noticeable, but it does not have manual settings.

The smartphone platform does not support two SIM cards in 3G/4G at the same time, that is, SIM cards from operators such as Tele2 will not work in 3G on voice communication if a card from another slot is assigned for data transmission in 4G (Tele2 cards simply cannot work in 2G). The standard interface allows you to select a specific card for each of the functions in advance or directly during the connection. Cards work in Dual mode SIM Dual Standby, there is only one radio modem.

Initially, a fairly large number of additional programs are preinstalled in the smartphone. Some of them are useful, such as file manager, navigator 2GIS, office suite WPS Office, but most of them are free simple games or demos of better games. All these applications, if desired, can be downloaded independently, that is, basically they are free garbage, which only clogs the already catastrophically small storage. It's good that any third party applications can be manually removed without any problem. The standard keyboard supports stroke type Swype.

To listen to music, a music player is designed with a pleasant-looking interface and fairly rich settings for the built-in equalizer. You can manually influence bass saturation and surround sound virtualization. The sound quality is average, it corresponds to the level of the device: both in the headphones and in the main loudspeaker, the sound is quite loud, clear, but unpretentious, unsaturated, monophonic, with a predominance of high frequencies. If you manually add bass using the equalizer, then the sound becomes muffled, less sonorous.

The built-in microphone does not shine with special sensitivity, but the recorder records sound sources located close to each other quite well. There is a built-in FM radio with the ability to record programs from the air, there are no complaints about its sensitivity, the radio works properly.

Performance

The Micromax Canvas Juice A1 hardware platform is based on the entry-level Qualcomm Snapdragon 210 SoC, made using the 28 nm process technology. The configuration of this chip includes 4 Cortex-A7 processor cores operating at a frequency of up to 1.1 GHz. The video accelerator Adreno 304 with a frequency of up to 400 MHz is responsible for graphics processing. The amount of RAM is 1 GB (LPDDR3), in reality, about 400 MB of them remain free. User storage initially is only 3.57 GB out of a total of 8 GB, that is, you can’t do without a memory card here.

Qualcomm Snapdragon 210 - SoC is very simple, even some alternative entry-level platforms show better results in tests, including the popular on this moment manufacturers MediaTek MT6737. The Snapdragon 210 is equipped with low-power, low-frequency Cortex-A7 processor cores and the same entry-level video accelerator.

However, in real work there were no serious problems in the operation of the interface and applications. The device adequately copes with its main tasks, the desktops scroll without sticking, applications open quickly, the interface does not “slow down”. I even managed to play popular, albeit not the most recent games, such as Dead Trigger 2, World of Tanks, at minimum settings without noticeable slowdowns. However, the user should clearly understand that without additional purchased microSD cards in this smartphone for such purposes will constantly lack memory.

Testing in comprehensive AnTuTu and GeekBench tests:

For convenience, we have summarized all the results obtained by us when testing a smartphone in the latest versions of popular benchmarks in tables. Several other devices from different segments are usually added to the table, also tested on similar latest versions benchmarks (this is done only for a visual assessment of the obtained dry numbers). Unfortunately, within a single 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 they once passed the “obstacle course” on previous versions test programs.

Testing the graphics subsystem in 3DMark gaming tests, GFXBenchmark and Bonsai Benchmark:

When tested in 3DMark for the most productive smartphones now it is possible to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (due to which the speed can rise above 60 fps).

Browser cross-platform tests:

As for benchmarks for assessing the speed of the javascript engine, you should always make allowances for the fact that the results in them depend significantly on the browser in which they are launched, so that the comparison can only be truly correct on the same OS and browsers, and this possibility is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

AndroBench memory performance test results:

thermal images

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

It can be seen that the heating is localized in the upper part of the device, which apparently corresponds to the location of the SoC chip. According to the heat chamber, the maximum heating was 36 degrees (at an ambient temperature of 24 degrees), which is relatively small.

Video playback

To test the "omnivorous" when playing video (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 Web. 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 versions using processor cores alone. Also, do not expect everything from 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 table.

According to the test results, the test subject, as is often the case, was not equipped with all the necessary decoders that are needed to fully play most of the most common multimedia files on the network, in this case, sound ones. To successfully play them, you will have to resort to the help of a third-party player - for example, MX Player. True, it also needs to change the settings and manually install additional custom codecs, because now this player does not officially support the AC3 audio format.

Format container, video, sound MX Video Player Regular video player
1080p H.264 MKV, H.264 1920×1080, 24fps, AAC plays normally plays normally
1080p H.264 MKV, H.264 1920×1080, 24fps, AC3 not playable

1080p H.265 MKV, H.265 1920×1080, 24fps, AC3 video plays with delays, no sound not playable

Further testing of video playback performed Alexey Kudryavtsev.

We did not find an MHL interface, as well as 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 “Methodology for testing video signal playback and display devices. Version 1 (for mobile devices) Red marks indicate possible problems associated with the playback of the respective files.

According to the criterion for displaying frames, the quality of playing video files on the screen of the smartphone itself is good, since in most cases frames or groups of frames can (but are not required) to be displayed with more or less uniform alternation of intervals and without frame drops. When playing video files with a resolution of 1280 by 720 pixels (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 its original resolution. The brightness range displayed on the screen corresponds to the standard range of 16-235: all gradations of shades are displayed in the shadows and in the highlights.

Battery life

The non-removable battery installed in the Micromax Canvas Juice A1 has large capacity at 4000 mAh, and this is the main trump card of this model. The device logically demonstrates very high level autonomy, the results in all tests are impressive. And if you take into account the undemanding SoC and the screen with a low resolution, then in real operating conditions the smartphone will adequately cope with daily tasks for a couple of days without recharging. In general, such a smartphone is indispensable on a long journey, which was emphasized. But everything, of course, will depend on your use case. The developers themselves promise up to 6 hours of talk time and up to 350 hours of standby time, and this is generally close to the truth.

Testing has traditionally been conducted at normal power levels without power saving features.

Continuous reading in the Moon + Reader program (with a standard, light theme) at the minimum comfortable brightness level (brightness was set to 100 cd / m²) with auto scrolling lasted until the battery was completely discharged for 19 hours, and with continuous viewing of video in high quality (720p) with the same brightness level home network Wi-Fi device operates for about 14 hours. In 3D gaming mode, the smartphone worked for 7 hours.

At the same time, the bulky battery charges quite quickly: the battery is completely filled from the supplied AC adapter within a little over 2.5 hours with a current of 1.9 A at a voltage of 5.5 V. Wireless charger not supported.

Outcome

Micromax Canvas Juice A1 is already available in official Russian retail at a price about 8 thousand rubles. Someone may consider this price too high for a smartphone, which, at least, still needs to buy a memory card. The Micromax Canvas Juice A1 has an entry-level hardware platform (but still Qualcomm) and modest sound capabilities, a high-quality fairly bright screen, an unexpectedly decent camera for its level, as well as a basic set of communication capabilities with support for three navigation systems and all frequencies common among Russian operators. LTE. The device is solid, with a practical case, there are not enough stars from heaven, but as a reliable workhorse with a guaranteed long battery life, it may well arouse interest in a certain part of the audience for which these qualities come first.

For those who lack the fingerprint authorization function, an improved modification of this model was later announced, called the Micromax Canvas Juice A1 plus (Q4260). It is curious that it is not only equipped with a fingerprint sensor, but also works on a different hardware platform - MediaTek MT6737V with a frequency of processor cores up to 1.25 GHz (but the same 1 GB of RAM). Apparently, it will be a slightly more productive model, but it will also cost a thousand more than the original.

In conclusion, we suggest watching our video review of the Micromax Canvas Juice A1 (Q4251) smartphone:

Micromax Canvas Juice 2 Q392, recently released to the domestic market, has become a representative of the line of "long-livers" of this manufacturer. It was equipped with a 4,000 mAh battery. But after all, only a large battery is not enough for a sophisticated user, so Micromax implemented several interesting features here. can a smartphone offer users anything beyond that? Let's figure it out.

Appearance

The front panel of the smartphone is black and covered with Gorilla Glass 3, so don't be afraid of scratches. Along the entire perimeter there is a border, almost invisible to the eye, but slightly sticking out and quite recognizable to the touch. At the top is a speaker and a front camera eye.

The back cover of Micromax Canvas Juice 2 is gray. From a distance, it seems metallic, but plastic is immediately recognizable to the touch. The edges are smoothed, so that as a result smartphone shape resembles Meizu devices, for example, MX5. But the elements at the top and bottom evoke thoughts of Huawei and iPhone gadgets. You might think that these are overlays, but in fact they are part of the lid. As a result, to get to the slots for the SIM card and microSD, you have to remove the entire panel. At the bottom of the lid there is a slot for the speaker, and at the top there is a camera eye and a flash.

The volume rocker and the power button are located on the right side, so that when you use them, your thumb rests on them. A good solution in terms of ergonomics.

If you remove the Micromax logo, then the gadget will be indistinguishable from many other smartphones. However, Micromax Canvas Juice 2 looks nice and, despite all the hackneyedness of the phrase, it fits perfectly in the hand, not trying to sneak out. It is very far from the frills of flagships, but do not forget that this is a state employee, and the use of more expensive materials would automatically raise its price.

Screen

Budget smartphone budget display. Micromax Canvas Juice 2 Q392 received a 5-inch screen with a resolution of 1280x720 pixels. The image quality is good: the display does not have enough stars from the sky, but there is nothing to complain about either. Viewing angles and color reproduction at the level, thanks for this IPS matrix. Those who wish can adjust the image to their liking using MiraVision technology. There are a couple of preset options in the settings: default and increased brightness. And the user can adjust the contrast, saturation, brightness, sharpness and color temperature.

The frames around the screen of the smartphone are quite thick, so that as a result the dimensions of the smartphone are 141x70 mm. Sometimes you have to intercept the device - fingers simply do not reach some parts of the display.

Hardware platform and performance

Micromax Canvas Juice 2 is powered by a 4-core Mediatek processor MT6580, which received 2 GB of RAM from the company - reference set for the upper budget segment. It was used in a bunch of smartphones, including Alcatel, Doogee and Asus Zenfone go. That's just the chip released last year - one of the most budgetary from MediaTek and, as a result, the smartphone, unfortunately, cannot boast of high performance.

With all everyday tasks, the gadget copes well, but the slowness is felt. Undemanding and not the most recent games work well: shooting Angry Birds will be no problem. With more powerful applications, problems are already arising - even Rayman Jungle Run, no, no, yes, it starts to slow down. It's better to just forget about modern hits like N.O.V.A.

Test results in benchmarks fully confirm subjective feelings. Micromax Canvas Juice 2 shows a naturally low result, which is easy to evaluate from the attached screenshots.

The smartphone is running stock Android 5.1. The manufacturer decided not to use any of his own shells, limiting himself to several pre-installed applications. Among them are the already mentioned MiraVision, "Camera", as well as a number of others, less significant.

cameras

The smartphone has a pair of sensors: 2 and 8 megapixels. The quality of the pictures is predictably average, but there are also positive aspects. The main camera shows an average result in daylight, but it is worth slightly worsening the shooting conditions - and instead of a clear picture, we get a solid “soap”. In addition, there are some problems with color reproduction here.

Not the most high quality the manufacturer decided to compensate with a wealth of modes and settings.

  • « live photo” resembles a similar mode in the new generation of iPhone, HTC Zoe and similar technologies. In fact, instead of a regular snapshot, a microvideo clip lasting a couple of seconds is made.
  • How exactly does the mode work? motion tracking' is not entirely clear. Most likely, we are talking about blur compensation when shooting moving objects, but there was not much difference with a regular photo;
  • « polygonal view” is an analogue of a panorama, but with its own nuances. The user will need to point the camera at the object, and then circle it with the camera in an arc. As a result, when viewing a picture, a scroll bar appears, with which you can look at the object from different angles;
  • « Beautiful face"- almost a standard feature of Chinese devices that improves selfies. Through simple adjustments, users can smooth out the tone of the face, but if you go a little too far, and instead of the natural skin color, we get a chalk mask.

Users can set exposure, white balance, ISO and other parameters. For video, a slow motion mode is available.

Communication and sound

Micromax Canvas Juice 2 received standard set wireless modules, that's just without LTE. On the one hand, this is a clear drawback, but with 3G connected instead of 4G, the gadget is able to work noticeably longer, and the Internet speed is enough to watch videos from the Web. Download the same big and 3D games it just makes no sense - the performance of the device is not enough for them. But there are two slots for SIM cards, and they work at the same time.

The interlocutor during the dialogue is always heard well, there are no problems on the other side either. The manufacturer calls an ultra-loud 96 dB speaker one of the main features of the smartphone. Micromax Canvas Juice 2 is really loud. That's just hand in hand with the quality of this feature, unfortunately, does not go. But you can hear the call under almost any conditions.

autonomy

The most forte smartphone. The 4,000 mAh battery holds a charge perfectly, which, with everyday use, is enough for more than 2 days with GPS and Bluetooth turned on. During active use(for example, in a game), the battery supply drops noticeably, which can be seen in the screenshots. However, it is worth noting that it is unlikely that the smartphone will be used so often for this - after all, it is focused somewhat differently.

Competitors

You can buy Micromax Canvas Juice 2 for 9,990 rubles. What can competitors offer for the same amount? If you put autonomy at the forefront - not much.

From more or less current models there is a Dexp Ixion EL350 Volt with a 4,000 mAh battery. You can find it for 6,650 rubles, but given the Spreadtrum processor and 1 GB of RAM, it is not certain that it can even cope with everyday tasks just as well.

ZTE Blade X3 costs 8,990 rubles and he has a similar problem - not the same powerful processor and only 1 GB of RAM. But the front camera is 5 megapixels.

The more compact Highscreen Power Four sells for the same 9,990. It has a 4.5-inch screen, a less powerful MediaTek MT6735M processor with a frequency of 1 GHz, only 1 GB of memory and cameras with more low resolution. And the battery capacity in the case of Highscreen does not always indicate good autonomy.

Summary

In general, Micromax Canvas Juice 2 leaves the impression of a kind of "workhorse". It can not boast of any outstanding performance, or spectacular design, or high-quality cameras, but at the same time it is distinguished by “endurance” that is rare for its segment. He will become a reliable companion. for those who are not interested in games or ultra-fast Internet, for those who primarily need a smartphone for communication, periodically checking mail and surfing the Internet. With this, the smartphone is doing well.

And if you look at the competitors, then everything turns out to be even more interesting. Yes, in your segment you can find devices with higher performance, but in their case, autonomy is to the detriment. You can find smartphones cheaper and with an equally capacious battery, but their performance leaves much to be desired. Micromax Canvas Juice 2 has become the golden mean among them and clearly deserves the attention of buyers.

Accelerometer(or G-sensor) - device position sensor in space. As a main function, the accelerometer is used to automatically change the orientation of the image on the display (vertical or horizontal). Also, the G-sensor is used as a pedometer, it can be controlled by various functions of the device by turning or shaking.
Gyroscope- a sensor that measures the angles of rotation relative to a fixed coordinate system. Able to measure rotation angles in several planes simultaneously. The gyroscope together with the accelerometer allows you to determine the position of the device in space with high accuracy. In devices that use only accelerometers, measurement accuracy is lower, especially when moving quickly. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- sensor, thanks to which the optimal values ​​​​of brightness and contrast are set for given level illumination. The presence of the sensor allows you to increase the operating time of the device from the battery.
Proximity sensor- a sensor that detects when the device is close to the face during a call, turns off the backlight and locks the screen, preventing accidental pressing. The presence of the sensor allows you to increase the operating time of the device from the battery.
Geomagnetic sensor- a sensor for determining the direction of the world in which the device is directed. Tracks the orientation of the device in space relative to the Earth's magnetic poles. The information received from the sensor is used in mapping programs for orientation in the area.
Atmospheric pressure sensor- sensor for accurate measurement of atmospheric pressure. It is part of the GPS system, allows you to determine the height above sea level and speed up the location.
touch ID- Fingerprint identification sensor.

Accelerometer / Illumination / Approximation

Satellite navigation:

GPS(Global Positioning System - global system positioning) - a satellite navigation system that measures distance, time, speed and determines the location of objects anywhere on the Earth. The system was developed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine the location by measuring the distances to the object from points with known coordinates - satellites. The distance is calculated from the signal propagation delay time from sending it by the satellite to receiving it by the GPS receiver antenna.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measuring principle is the same American system GPS navigation. GLONASS is intended for operational navigation and time support for ground, sea, air and space-based users. The main difference from the GPS system is that the GLONASS satellites in their orbital movement do not have resonance (synchronism) with the Earth's rotation, which provides them with greater stability.

Micromax Canvas Juice 2 is a medium-sized device, oriented, perhaps, specifically to the Asian market, where such devices are valued for their functionality at an affordable price.

Design and ergonomics

The device is made in a pleasant color scheme: The combination of deep black and steel colors makes the smartphone visually presentable, although lacking personality. With the display disabled, the device screen looks like black mirror which does its job well. In general, the smartphone looks monolithic and without unnecessary details.

There is no physical button on the front panel, the volume rocker and the power button are located on the right side - just under the thumb of the right hand. A small round speaker and front camera sit above the display. On the bottom side there is a microphone and a micro-USB connector, a mini-jack fits on the top.

The camera with a flash placed on the upper part of the rear panel looks quite stylish: the camera eye is framed by a small protrusion at the top, and a semicircle at the bottom. The main speaker in the form of a strip is at the bottom of the device wall.

The smartphone lies pleasantly in the hand, but the plastic cover gives it a mediocre device.

The cover of the device is removable. Hidden underneath is a memory card slot and two SIM card slots.

Screen

Micromax Canvas Juice 2 received a 5-inch IPS display with a resolution of 1280x720 pixels, supports multi-touch, pixel density - 294 ppi.

The colors are clear, saturated, which is typical for Micromax devices. However, the brightness of the screen of the device greatly hurts the eyes. Even with the adaptive adjustment turned on, the smartphone is too bright. Therefore, for comfortable use, I had to turn off the function and set the brightness slider to almost the very minimum.

The screen is protected by Gorilla Glass 3, which is pleasant to the touch, but slightly slippery. When typing and scrolling pages, the smartphone's screen does not always respond to touch, the device requires precision with a finger and more effort.

Sound

The sound of a smartphone requires a separate word, since the developers themselves note its volume. On the box, a figure of 96 dB is declared - in terms of volume, it is close to a subway car passing in the immediate vicinity.

The device is really loud. It cannot be said that he great quality sound, but nevertheless it is quite digestible. On some particularly “difficult” songs at full volume, the smartphone inevitably wheezes and trembles in the hands.

The chip with a very loud speaker is not entirely clear and looks more like an anachronism. Perhaps this feature is a weighty argument in the company's home market, but in the Western market, smartphones have long competed in sound quality, not volume.

From the headphones that come with the device, you should also not expect outstanding sound quality: the accessory corresponds to its price category.

Camera

The main camera of the smartphone is equipped with 8 megapixels, the front camera is only 2 megapixels. The quality of shooting, of course, leaves much to be desired, but the device has a couple of noteworthy features.

On the main camera, you can shoot text well, the claims for sharpness and clarity of image transmission are minimal. But the color rendition of the pictures is lame. FROM front camera the same story, in addition, the square pixels of the image are clearly visible in the picture.

However, the Micromax Q392 has interesting features, such as a feature called "Multi-Angle View". It is similar to panoramic shooting, but allows you to move the slider around the image. It turns out something in the spirit of 3D shooting. The function is especially interesting in circular selfies or, conversely, in shooting the surrounding panorama. Unfortunately, you can view the resulting image only on the smartphone itself and it will not be possible to transfer it.

There is also the “Beautiful Face” function, which is standard for “Asian” devices, which turns the skin in the photo into chalk. There is a Motion Tracking option that allows you to do something similar to a gif-animation with the ability to select specific frames that will be included in the final shooting result.

Hardware specifications and user experience

Canvas Juice 2 shows good results in terms of speed and copes with the usual tasks - for example, checking email, browsing social networks, playing undemanding toys. Serious freezes were not observed.

Characteristics of the "iron":

Chipset: Mediatek MT6580
-Processor: Quad-core Cortex-A7 @ 1.3GHz
-Memory: operational - 2 GB, internal - 8 GB, slot for micro-SD (up to 32 GB)
-OS: Android 5.1
-micro USB v2.0
-4000 mAh battery

In the AnTuTu benchmark, the device scored a little less than 23 thousand points. The result is frankly weak, especially unimpressive characteristics of the device turned out to be 3D indicators. Approximately similar results are gained, for example, by Xiaomi Mi 2, Micromax Canvas Sliver 5, samsung galaxy A3.

At the same time, there are several points that are alarming and depressing. For example, a smartphone does not support 4G networks, but this is not so bad, because even in 3G networks the device performs very poorly. Simply put, the device has obvious problems with data transfer speed. As noted by owners of other Micromax smartphones, this problem characteristic of the entire line of devices.

Also Canvas Juice 2 is clearly out of memory. With the declared 8 GB of free disk space, the user gets only a little more than 4 GB. Of course, micro-SD will correct the shortcoming in the case of photos, videos and other content, but applications cannot be installed directly on it.

The smartphone vibrates very strongly, and there is no intensity adjustment slider in the settings. Many devices sin with this, especially noticeable after use. Samsung smartphones where there is such an adjustment.

However, the 4000 mAh battery really sets the device apart. For a day of moderately active use with data transfer turned on, the smartphone lost only 30% of the charge. Thus, on a single charge, the device will be able to work for 2-3 days.

Summary

The Micromax Canvas Juice 2 is a good device overall, but not without flaws.

The advantages of the device include light weight, concise, although not original design, 2 GB of RAM, interesting camera functions, a capacious battery and, of course, low price(for Russian retailers, it varies from 8 thousand to 9 thousand rubles).

Among the minuses are the lack of LTE and poor data transfer quality, too powerful vibration, problems with screen brightness, a weak camera and mediocre sound quality.
