Introduction

The CAT smartphone from the world-famous American corporation Caterpillar is an upgrade of the previous generation of the dust and waterproof CAT B15 device. The new B15Q received a new chipset, a new version of the Google Android operating system, more RAM and other little things.

In general, the device turned out to be extremely budget-friendly in terms of technical characteristics: the simplest quad-core processor from MediaTek, the simplest IPS display low resolution, weak battery, etc. However, the cost is by no means budgetary - about 15,000 rubles. It remains to be seen how good the protection of this model is.

Design, dimensions, control elements

As befits such gadgets, the CAT B15Q has impressive dimensions - 125x70x15 mm, however, we have seen larger ones, for example, teXet X-Driver - 139x73x18 mm. The B15Q is protected from water and dust according to the IP67 standard - complete protection from dust and short-term immersion in water to a depth of one meter. In addition, the CAT has passed Military Standard 810G testing for vibration, moisture, shock, temperature, and so on.



I conducted drop tests as follows:

  1. Dropped a smartphone from a height of 1.8 meters onto a floor covered with linoleum
  2. Dropped a smartphone from a height of 1.5 meters onto a tiled floor
  3. Immersed in water to a depth of 30 cm

All these procedures were carried out several times. The following conclusions were drawn. In both the first and second cases, the device was dropped 10 times. When dropped from a height of 1.8, the cover flew off and the battery fell out 7 times. When dropped from a height of 1.5 meters onto the tile, the lid flew off and the battery fell out 4 times. The CAT mostly fell on the corners, so they were a bit cramped. Several blows fell on the metal edges, which left dark gray jagged edges.






Immersed in water 5 times. The first time for a couple of minutes, the second time for 30 minutes, the third and subsequent times for a minute. The device behaved perfectly, but the touch screen did not respond, that is, use it in water touch screen useless. After removing it from the water and removing the back panel, I noticed that the water did not get on the vital “organs” of the smartphone, but the area not protected by the rubber gasket was wet.

For the most part, the CAT B15Q performed quite well in all tests. The only thing I didn’t like was the way the back cover closed: it seemed to me that it was secured with plastic holders extremely unreliably (during the “drop tests” one such loop broke).

The color of the device is black, the shape is rectangular with beveled corners. Anodized aluminum is used on the sides, the rest of the body is durable rubberized plastic with a soft-touch coating. Back panel has a relief coating, and in the center there is a recessed polished metal inscription “CAT”.



The smartphone fits more or less well in the hand, however, the thickness of 15 mm still affects it.



On the front side, in the top center, there is a speech speaker. It has medium volume and intelligibility due to IP67 protection. They can hear you well, but a little deaf.


On the right is the front camera, light and proximity sensors. Below the screen there are touch buttons “Back”, “Home” and “Menu”. Marked on the body with white translucent paint. There is a backlight, it is dim, but the symbols are visible during the day, and at night the backlight does not blind the eyes.


There is a microphone under the Back button. On top, under the rubber plug, is a 3.5 mm audio output. You can connect any headphones since the connector is shallow. On the right is the yellow power button. It presses surprisingly easily, the stroke is average. Usually in protected devices they are hard and inconvenient to use. This type is volume control and flashlight activation. They are located on the right. On the left under the rubber plug is microUSB. This is where you will have to “use” a proprietary cable, since only it reaches the connector recessed into the case. This is inconvenient, but what can you do - there is a certain price to pay for protection from dust and moisture.





On the back of the device there is a camera eye framed by a metal ring, a single-section LED flash, and a speaker. At the very bottom there is a latch on which the lid closes. Maybe the sample was unsuccessful, maybe the CAT B15Q devices are all like that, in general, the slider doesn’t go all the way to the left, that is, as I understand it, it doesn’t close the lid. Therefore, the socket can be removed quite easily; you just need to lightly pull the recess on the bottom end.





SIM cards of the miniSIM standard are installed in special slides on the left, under them there is a slot for a microSD memory card.

To summarize this section, it is worth saying the following: the CAT B15Q is not well protected because it weakness– the rear panel, which can cause problems if it is not fully pressed with the plastic latch. In addition, I think that the fastening loops should have been made of metal, and the base for the back cover should have been made from it.

Display

The screen diagonal of the CAT B15Q is 4 inches, the physical size is 51x86 mm. The frames on the right and left are 8 mm, on the top – 17, and on the bottom – 23 mm. The screen is protected by durable Corning Gorilla Glass. The official website does not say which generation of glass is used. In any case, it protects more from scratches and abrasions than from strong impacts. During use, not a single scratch appeared on the display.

There is no oleophobic coating: fingerprints abundantly cover the entire surface of the screen and can be wiped off with great difficulty with a microfiber cloth. If there is an anti-reflective layer, it is weak.

The screen resolution is low – 480x800 pixels. The matrix is ​​not made using IPS technology, so viewing angles are small. When tilted away from you, the brightness and contrast decrease, towards you - the colors are inverted, to the right and left - the colors acquire a yellowish tint.

Maximum white brightness is 418 cd/m2, maximum black brightness is 0.9 cd/m2, contrast is 460:1. The color gamut slightly exceeds sRGB in the red and green areas.

Battery

It uses a lithium-ion (Li-Ion) battery with a capacity of 2000 mAh, 3.7 V, 7.4 Wh. The manufacturer gives approximate operating time: in standby mode – up to 21 days, in talk mode – up to 16 hours.

In video playback mode (MP4, 640x480 pixels) at maximum brightness and volume in the headphones, the battery ran out after about 5 hours. If you use 3G, make about 10-15 calls lasting 1-2 minutes, “take pictures” for 20 minutes, then the battery will run out in 9 hours.

Charging will take approximately 4 hours from USB and 2 hours from a standard AC adapter.

Communication capabilities

The phone operates in 2G (GSM/GPRS/EDGE, 850/900/1800/1900 MHz) and 3G (850/900/2100 MHz – SIM1 only) cellular networks. Available Bluetooth version 2.1 (EDR) for file and voice transfer. Wireless available Wi-Fi connection IEEE 802.11 b/g/n. The device, of course, can be used as an access point ( Wi-Fi Hotspot) or modem. In the settings, this item is listed as “Modem mode”. There is Wi-Fi Direct.

There is GPS. It works more or less normally, at least I didn't have any problems.

Memory and memory card

This model has 1 GB of RAM. Of this amount of RAM, on average, just under 600 MB is free.

Built-in memory 4 GB, approximately 2 GB available for data storage. There is a slot for a microSDHC memory card up to 32 GB.

Cameras

The CAT B15Q smartphone has two camera modules: a 5 MP main one with autofocus, and a 0.3 MP front camera. The aperture of the first is F2.4, the second is F2.8.

Oddly enough, the 5 MP module produces quite “credit” images: clean, without obvious noise, excellent detail, white balance is always correct. Focus is slow and sometimes makes mistakes. There is no tap exhibit.

The front camera is weak. There's nothing to talk about.

The device records video in FullHD resolution at 30 frames per second. However, the quality leaves much to be desired; 5 megapixels is not enough to unlock the potential of FHD resolution. The sound is clear but quiet, stereo.

Video file characteristics

  • File Format: 3GP
  • Video codec: AVC, 17 Mbit/s
  • Resolution: 1920 x 1080, 30 fps
  • Audio codec: AAC,128 Kbps
  • Channels: 2 channels, 48 ​​kHz

Performance and Software Platform

Somehow it turned out that all the latest smartphones that I tested were equipped MediaTek chipset MT6582 (4 cores, Mali-400 graphics). Budget devices from all companies are usually equipped with this chip. To avoid repeating yourself, you can read and watch the review of LG Fino and Bello, for example. The CAT B15Q smartphone behaves stably, does not freeze or slow down.


In this review, we will look at the TOP 4 best smartphones and phones from Caterpillar 2017. We will pay attention to the most popular and popular models to understand them strengths and distinctive qualities.

Caterpillar Cat B25 phone

The Caterpillar Cat B25 model is one of the most popular in the collection of the American manufacturer. The phones are produced in China, but they are famous for their high quality and excellent functionality.

  1. Design and equipment. A classic and attractive candy bar, which has a brutal and at the same time futuristic design. As a result, the phone stands out against the backdrop of a gray mass of similar gadgets, which practically do not differ in anything except the logo. The unique appearance of the main camera, which is located on the back surface, rubber lining and unsurpassed quality of finishing - everything speaks of the premium nature of the mobile phone. The device is offered in a yellow box with the company logo. The Caterpillar Cat B25 package includes the gadget itself, a charger, instructions and a connector for connecting the device to a computer. The main feature of the device is the keyboard, which is equipped with wear- and abrasion-resistant buttons.
  2. Display. A distinctive feature of the phone is its unique screen, which is based on advanced Quarter VGA technology. The two-inch display boasts a TFT matrix and its innovative shockproof properties. The presence of an IP67 certificate means that the screen can even withstand immersion in water, although not deeper than 1 meter.
  3. Performance The Caterpillar Cat B25 mobile phone is powered by a MediaTek MT6235 processor clocked at 208 MHz. Only 256 MB of memory is available to the user, but it can be increased up to 8 GB using MicroSD memory cards.
  4. Multimedia. Caterpillar Cat B25 can't boast of luxury multimedia capabilities. The main 2 megapixel camera shoots in a resolution of 1920x1080, which is quite small for modern realities. To justify the manufacturers, we can only say that the phone is not intended for taking photos and videos, but is positioned as an indestructible device for communication in any conditions. The camera's autofocus is also lame, detecting faces every once in a while.
  5. Autonomy. The main advantage of the Caterpillar Cat B25 gadget is its 1300 mAh lithium-ion battery, which is more than enough for 10 hours of talk time. Thanks to minimal energy consumption, the mobile phone can operate in standby mode for more than 300 hours.
  6. Additionally. Additional features include a dust- and moisture-resistant case, as well as an FM receiver. To store musical compositions, you can use the built-in advanced media player with the possibility of fine-tuning for each user.
The price of Caterpillar Cat B25 in Russia is 4,000 rubles. A video review of this device is presented below:

Smartphone Caterpillar Cat S30


Caterpillar Cat S30 is the latest and most advanced model of the American manufacturer, which premiered at the IFA world exhibition. The affordable device can easily compete with flagship smartphones from Korean manufacturers.
  1. Design and equipment. This smartphone model comes in a yellow box small size. There are no features or compartments inside: the box is quite simple and stylish. The package is also weak - it consists of a device, a charger and a Micro-USB cable. The design of the smartphone turned out to be unique. Compared to other models in the American concern's line, the Cat S30 boasts more elegant and modern shapes. The brutality that is inherent in the manufacturer’s products is not noticeable here at all. All this made the device more comfortable to use: it fits perfectly in the hand, and the body material is pleasant to the touch. According to the company, the device can spend about an hour underwater without compromising its functionality or integrity.
  2. Display. The screen can be called the most ill-conceived and weakest part of the smartphone. The Cat S30 is equipped with a 4.5-inch display with a resolution of only 854x480 pixels. This is a record low quality even for budget phones, despite the fact that the manufacturer characterizes its unit as a representative of the middle segment. One consolation is the enhanced brightness made possible by the use of third-generation Gorilla Glass.
  3. Performance Cat S30 is powered by Qualcomm Snapdragon 210 version processor. The heart of the phone has four cores that operate at 1.1 GHz. The corporation's engineers decided to use the Adreno 304 GPU as a graphics accelerator. 1 GB of RAM will surprise few people today, but this is enough for the Cat S30 to fulfill all its obligations. There is only 3 GB of internal memory, so you can’t do without using cards up to 64 GB.
  4. Multimedia. The device is completely devoid of any hints that it was not created for listening to music. The melodies play very loudly, and the sound quality in the headphones is high. The only drawback is the proprietary digital noise reduction and audio processing system, which is clearly not fully thought out. The main 5 MP camera is capable of shooting video in HD resolution and boasts automatic focus and LED flash. Pleases a large number of settings that allow you to control shooting, change its quality and other parameters. The device is equipped with only a 2-megapixel front camera, which again is not enough for modern realities. In defense of the smartphone, it should be noted that there is no color noise in the resulting images.
  5. Autonomy. Cat S30 is equipped with a 3000 mAh battery, which is enough for several days active use gadget. In talk mode, the smartphone can work for 9 hours. This is an impressive indicator for this type of device. In modern gaming mode, the phone will last about 7 hours without any problems, and when shooting video it lasts for 11 hours.
  6. Additionally. The Cat S30 model runs on the Android 5.1 operating system; a proprietary shell is not used. The smartphone is capable of working with two SIM cards simultaneously and you can assign a specific ringtone to each of them.
The price of Caterpillar Cat S30 in Russia is 16,000 rubles. Below is a detailed video review of this gadget:

Smartphone Caterpillar Cat S50


Caterpillar Cat S50 is a rugged smart phone that features a powerful processor, LTE support and the ability to withstand enormous loads and moisture.
  1. Design and equipment. This model is one of the most brutal and terrifying. However, this is all done for the sake of protection from falls, exposure to moisture and other factors. The impact-resistant housing is secured with large bolts, the side is made of metal, and the corners of the lid are made of high-quality rubber. Even the main camera resembles a nut to some extent. The configuration of the gadget is almost no different from other devices from the manufacturer.
  2. Display- the main distinguishing feature of the Caterpillar Cat S50. The 4.7-inch screen is bright and rich. Having a resolution of 1280x720 pixels, it is able to distinguish touches with a wet hand. High degree Protection is guaranteed by the presence of Gorilla Glass 3, which is famous for its impact resistance, resistance to stains and dust.
  3. Performance. Under the back of the Caterpillar Cat S50 is a quad-core Qualcomm Snapdragon 400 processor clocked at 1.2 GHz. With 2 GB on board, the smartphone can cope with all the tasks assigned to it without slowdowns or obvious glitches. Thanks to the graphics accelerator, even game lovers can enjoy everything the latest news gaming industry.
  4. Multimedia. The 8 MP main camera boasts high-quality automatic focus and the ability to record video in 1080p resolution. The front camera here is nominal - VGA option. The sound in the smartphone is excellent, so music lovers will definitely like it.
  5. Autonomy. The Caterpillar Cat S50 does not boast good autonomy. The 2630 mAh battery is barely enough for a day of active use of the phone. IN game mode The device will last no more than 3 hours, and in talk mode - up to 10 hours.
  6. Additionally. Among additional benefits Caterpillar Cat S50 can be distinguished by the IP57 standard, which guarantees protection from dust and allows you to dive with your phone to a depth of up to one meter. The presence of military standards ensures the ability to operate the gadget even at -25C frost.
The price of Caterpillar Cat S50 in Russia is 25,000 rubles. More detailed information is contained in the video review:

The TOP 4 best smartphones and phones from Caterpillar in 2017 described above will definitely appeal to connoisseurs of shock-resistant devices. At affordable price gadgets boast high quality and excellent autonomy.

"Indestructible" phone for workers and builders

Walking once, already at the end of last year’s IFA 2012 exhibition, through the most distant and secluded corners of its pavilions, we came across a small, but very interesting for us, stand with representatives mobile technology, still unknown to us. Cute, unusual, brutal-looking, thick and ribbed mobile devices not only instantly attracted the attention of the sophisticated journalistic public with their amazing “armour-equipped” design, but also became participants in a “cruel” show staged by company representatives right on the spot. Before our eyes, phones that have a strong (which could be understood even from the unusual appearance) protected from dirt and water, they were thrown directly into construction concrete mixers, mixed together with fresh concrete, and then, casually rinsed with running water from a garden hose, they demonstrated to the stunned spectators the preserved full functionality of the mobile devices that had gone through this “hell.”

Everything became clear as soon as it became clear who exactly was the initiator of all this “disgrace.” The company demonstrating “cruel” treatment of fragile electronics turned out to be the famous American corporation Caterpillar, a world leader in the production of construction and mining equipment. Accordingly, the “electronics” that such a company had a hand in producing also turned out to be far from fragile. Participants in that memorable show included several completely indestructible mobile phones and even one smartphone, on the body of which was the logo of this famous construction corporation. That smartphone was called Cat B10, and, of course, at that moment we really wanted it to become the hero of one of our reviews.

However, it took much longer than we would have liked before we were able to get one of these super-secure smartphones from a renowned manufacturer of heavy duty equipment for testing. By that time life cycle The Cat B10 smartphone was already coming to an end, and in its place came a new “replacement” - the owner of no less characteristic external data, a smartphone called Cat B15. Naturally, we chose for our tests a more recent model, which only recently began its journey to the market.

Since we always take on reviews with great interest and test all dust and waterproof devices that appear on our market, we have already accumulated some experience on this topic. Summarizing most of these studies, we most often come to the same conclusion: almost all of the dust and waterproof mobile devices presented on our market (and the vast majority of them now belong to the Japanese Sony) cannot be fully called secure devices. None of the protected Sony devices on our market, for example, have protection against shocks and falls, and most of them are not even equipped with locking locks on removable covers. If such phones are dropped onto a hard surface, the plastic cover latches can simply bounce off, and then all the measures provided by the manufacturer to protect against dirt and water getting into the case lose all meaning - the cover flies off, the filling is exposed. If such a phone fell, say, into a puddle on hard asphalt, then such a fall could end just as badly for it as for any other mobile device that does not have special protection against water. Thus, this type of device can be classified, according to the classification accepted in the automotive market, not as an SUV, but rather as an “SUV” - pampered “city dwellers” who demonstrate external attributes more than actually possessing the capabilities of an “all-terrain vehicle”. Such protected mobile devices can only be carefully brought into fresh water and kept there for half an hour at a depth of half a meter - that’s all.

In the pictures: Cat B15 in comparison with dust-proof and moisture-proof Sony smartphones (Xperia acro S, Xperia V and the latest of the new products - Xperia ZR), as well as with one of Lenovo’s rugged smartphones on a similar hardware platform (Ideaphone A660).

Moreover, we were interested in getting one of the real “SUVs” for testing, designed for truly harsh operating conditions. Caterpillar's involvement in the production of a rugged mobile device can be easily explained: with almost a century of experience in the most difficult and remote working conditions, these people know what real special equipment should be like for difficult operating conditions. By the way, the company is also the manufacturer of the famous yellow non-wearable boots, which are so loved by workers and builders all over the world (in the very first photo, the girl is dealing with phones in just such boots). Recently, they have also been offered reliable electronic mobile assistants.

Naturally, we did not expect anything special from the performance of the Cat B15 smartphone. The usual MediaTek platform inside, low screen resolution, modest hardware data - all this was known before testing began. However, this is not what people who buy such secure devices are guided by. They are interested, first of all, in protective qualities, and the hardware filling is a minor matter. However, as professionals in our field, this part of the issue always worries us very much. Therefore, we finally got our hands on an overseas smartphone and carried out all the experimental studies with it that we carry out with any other mobile device that ends up in our test laboratory. Of course, we did not test the protective properties of a mobile phone by dropping it from the roof of a house or placing it under the wheels of a car - that would have been too much. The Cat B15 smartphone went through exactly the same thing in our hands standard testing according to the methodology we developed, like all the other heroes of our reviews. Here's our detailed report on it.

The smartphone goes on sale in an attractive small package in the form of a rectangular box made of thick cardboard with a signature bright yellow color and several laconic inscriptions. It’s nice to pick it up: everything is neat, strict, high quality - everything shows that the product was produced by a serious manufacturer.

The box contained a not very rich set - only the essentials: a small charger, a connecting cable, a modest wired stereo headset with ordinary non-in-ear headphones, and documentation. It is noteworthy that the operating instructions here are made in the form of a thick book with cut off corners: in terms of dimensions, it is a copy of the smartphone itself. It's a small thing, but nice. I was also pleased with the set of spare parts included in the kit in the form of rubberized caps and even metal screws for attaching them to the body. Everything is thought out to the smallest detail: if the rubber gasket wears out, or the slot of the old screw breaks off when dismantling the cover, then a replacement will be included in the kit. It is clear from everything that the manufacturer prepared its “SUV” for truly the most severe operating conditions.

About security

The Cat B15 smartphone is officially certified to IP67 dust and water resistance, which means full protection from the penetration of dust, as well as protection from the effects of low pressure water jets from all sides, and can be located at a depth of 1 meter in fresh water for up to 30 minutes.

As mentioned above, the Cat B15 smartphone is a device with a completely different level of protection than most dust and waterproof smartphones from “traditional” mobile equipment manufacturers currently on the market. Its significant difference is protection, not only from dust and water, but also from falls: the rubberized body of the hero of today’s review has increased impact resistance. As for official data on this issue, in the operating instructions the manufacturer states that the phone has been tested to protect against falls from a height of 1.8 meters (human height), and guarantees that the smartphone will not be damaged in such a fall. What follows is an interesting phrase: the company guarantees protection of the device from accidental shocks and falls, but is not responsible for the consequences of deliberately “cruel” handling of the device. However, this is all, of course, reinsurance: the thick rubberized body of the Cat B15 will certainly be able to withstand falls from much greater heights. Advertising phrase on the brand name it sounds something like this: “Drop it from a height of 1.8 meters upside down on concrete, and it will bounce back, even if the smartphone falls face down.” The display, by the way, is covered with Corning Gorilla protective glass with the ability to control it with wet fingers (Wet Finger Tracking).

We checked the last possibility, and even tried to take pictures with a smartphone camera under water - everything was confirmed. The smartphone can not only be operated with wet fingers (which is very important in extreme conditions of rain, snow, etc.), but can also easily withstand immersion in water to a depth of 1 meter for 30 minutes. Photography underwater is, of course, not included in the official list of capabilities of this “SUV”, but after the declared underwater shooting function of the Sony Xperia ZR, we decided to check this capability with the Cat B15.

This did not present any difficulties, because the Cat B15 smartphone, like the Sony Xperia ZR, is equipped with a hardware key to control the camera, which means it is really capable of shooting underwater, although this is not part of its official “responsibilities”. Of course, in the absence of a built-in flash, you can’t expect anything outstanding artistically from underwater photography with the Cat B15 camera - the quality of the photos is rather modest. But the fact remains: due to the presence of a hardware photo button, underwater photography with the Cat B15 camera is quite possible. Let us recall that when full immersion Not a single screen will perceive finger touches, which means it is impossible to take pictures by clicking on virtual icons on the display - only if there is a hardware camera shutter key.

Appearance and ease of use

So, the Cat B15 smartphone is equipped with a shock-resistant case that can protect fragile electronic components not only from dirt and moisture, but also from falls. This is where the features of the body of this communicator follow: rough, angular, very thick and quite heavy. The thickness of the case is justified by protection from shocks and falls - thick rubberized plastic surrounds the electronic filling with impenetrable protection. It is difficult to say for certain whether there is a metal frame inside under this layer of plastic: the manufacturer calls its case “aluminum body,” but this may just be a play on words, or this phrase may only mean aluminum protective pads screwed to the sides of the device. In any case, you can feel the real power and impenetrability of these thick walls, which makes you believe in the absolute reliability of the device in terms of impact resistance.

The phone, as already mentioned, is very thick - almost 15 mm, which is a kind of “anti-record”. But, naturally, it would never even occur to anyone to find fault with the excessive thickness of this smartphone - everyone understands that this is dictated by structural features related to the ability of the smartphone case to withstand shocks and falls.

There are no glossy or shiny surfaces here - only matte rubberized plastic and rough metal of the side covers. Due to this, the phone is firmly held in the hand and does not slip. There is, in fact, nowhere to leave fingerprints here except on the screen itself - the rest of the body is completely indestructible.

The Cat B15 has a removable plastic cover that, unlike most "traditional" mobile equipment manufacturers, has a real locking lock, preventing it from opening due to impacts. This sets the new product apart from analogues from Sony, Samsung and others in the sense that the plastic latches may not hold up, but the lock will still hold the lid in place when dropped and will not allow the electronic filling and contacts to be exposed. This important difference, which allows us to recommend this smartphone to rescue workers, extreme athletes, travelers, and simply fishermen and hunters, for whom the fault tolerance of the equipment around them is most relevant and sometimes vital.

Under the cover are protected from moisture and dirt slots for SIM cards and memory cards, which after installation are supported by the battery. Thus, it is impossible to get to any of the replacement cards here without removing the battery.

The phone supports dual SIM cards (Mini-SIM format is used) and microSD memory cards up to 32 GB. All pyramid-type cards are installed one above the other and do not require frequent replacement: they also have to be removed one after another, it is not possible to remove the lower ones separately, and it is very inconvenient to remove them from the slot-like slots. There’s really nothing to pry off a stuck card - you’ll have to use tweezers if something happens, and it’s better not to think about using a Micro-SIM with an adapter at all: it will be very difficult to insert it and take it out again.

The front panel is almost completely covered with durable scratch-resistant Corning Gorilla glass. The screen is framed by thick half-centimeter frames - some of them are plastic, some are metal. Hidden under the glass are the eyes of the sensors and the front camera, as well as the lower three buttons for controlling the system and applications. The buttons under the screen are touch sensitive and have a dim milky backlight, the duration of which cannot be adjusted using standard means. The screen and touch buttons respond quite comfortably to finger touches - there are no problems with this, no erroneous presses were noticed, nor any sluggish response.

All other controls and connectors are traditionally located along the edges of the device. At the top end, the power button is adjacent to the 3.5 mm audio output, and on the side between the volume keys there is a camera control button. The Micro-USB connector is hidden under a cover on the left side; the bottom end is left empty. The main microphone is located on the front edge under touch buttons. All connectors are securely covered with tight rubber plugs, and they are not secured to the case using traditional flexible “tails”, but are screwed on with real metal screws. These parts are replaceable and replaceable.

All mechanical buttons They have a fairly hard ride. They hardly stick out from the body, but the response when pressed is quite distinct. The volume here is adjusted not by a two-position rocker, as is the case in most cases, but by two separate independent buttons. The camera control key located between them is unable to activate shooting in sleep mode - in any case, you must first unlock the smartphone, which is logical: we have a product thought out to the smallest detail, in which nothing should work by itself or be accidentally pressed in your pocket.

And finally, a few minor comments. Firstly, the metal side covers didn’t exactly add beauty to the device - the completely one-color rubberized body of the Cat B10 with its black ribbed sides looked somehow more strict and complete in terms of design. And there’s nothing to say about the ease of holding it in your hand: metal certainly glides better in wet fingers than rubber. Secondly, the Micro-USB connector here is recessed so deeply that not every third-party USB cable will fit. The owner of the device needs to remember this, otherwise you can take another cable on the road, relying on their versatility, and be left without charging for the entire time. As for the color schemes, there is no variety here: we have not found any mention of any other color options for the Cat B15 than the one that was on the test specimen that was in our hands.

Screen

The Cat B15 smartphone is equipped with a modest TN touch matrix measuring 53x82 mm, diagonal - 102 mm (4 inches), resolution - 800 × 480 pixels, pixel density is 233 ppi.

The display brightness has both manual and automatic adjustment, the latter based on the operation of the light sensor. Multi-touch technology allows you to process up to five touches simultaneously - tested AnTuTu program Tester. The screen is quite responsive, there are no problems with this. The smartphone also has a proximity sensor that blocks the screen when you bring the smartphone to your ear.

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

The smartphone screen is covered with a glass plate with a mirror-smooth surface and, judging by the reflection of objects in it, if it has an anti-glare filter, it is a very weak one. There may be a special oleophobic (grease-repellent) coating on the outer surface of the screen, but its effectiveness is very low; as a result, the screen is easily covered with fingerprints, which are relatively difficult to remove.

When manually controlling the brightness maximum value was 316 cd/m², the minimum was 13 cd/m². As a result, even at maximum brightness in bright daylight, the readability of information on the screen will not be very high. There is automatic brightness adjustment based on the light sensor (apparently it is located to the left of the front camera). In complete darkness, the auto-brightness function reduces the brightness to 13 cd/m² (too low), in bright conditions artificial light In an office, the brightness is set to 56 cd/m² (more or less), in a very bright environment it increases to 88 cd/m² (and needs to be increased to the maximum). In automatic mode, as external lighting conditions change, the screen brightness increases and decreases, but this mode is of little use, since the brightness is clearly set below the required level. The backlight brightness is modulated with a frequency of about 42 kHz, this is a very high frequency, so there is no visible flickering of the image on the screen.

This screen has a TN type matrix. The micrograph demonstrates a typical TN subpixel structure (or rather, the lack of structure):

The screen has good viewing angles in the horizontal direction, but at the slightest upward deviation they are inverted dark shades, and when deflected downwards - light. When viewed perpendicularly, the uniformity of the black field is low, since along the border of the screen the black field is noticeably brightened. The contrast is good - about 800:1. The response time for the black-white-black transition is 11 ms (8.6 ms on + 2.4 ms off), the transition between halftones 25% and 75% (according to the numerical value of the color) and back takes 24 ms in total. Short response times are perhaps the only positive property of this matrix. The gamma curve constructed using 32 points did not reveal a blockage either in the highlights or in the shadows, and the index of the approximating power function turned out to be 2.45, which is higher than the standard value of 2.2, while the real gamma curve coincides well with the power dependence:

Color gamut less than sRGB:

Apparently, the matrix’s light filters mix the components with each other, and the spectra confirm this. This technique allows you to increase the brightness of the screen with the same energy consumption for the backlight, but the colors lose their saturation.

The balance of shades on the gray scale is disgusting, since the color temperature is above the standard 6500 K, the deviation from the blackbody spectrum (delta E) is high, and both parameters vary greatly from shade to shade:

We can conclude that the screen is definitely not strong point of this device.

Sound

In terms of sound, the smartphone cannot boast of anything special. Both speakers are not loud enough, especially the external one. Obviously, the general specific internal arrangement, organized to protect against moisture, has an effect. The speaker is additionally covered with a special protective membrane that does not allow water to pass through, so the sound is duller and quieter. This effect is found in many waterproof models (the exception, by the way, was the Lenovo Ideaphone A660 from the comparison table - this smartphone, although protected, is simply deafening with its loud sound). There are no special distortions in the telephone dynamics; the voice of a familiar interlocutor, intonation and timbre are well recognizable, but the voice still sounds dull, as if from behind an obstacle. The external speaker grille is located at the back, so the sound is also significantly muffled by the surface when the phone is lying on the table (screen up).

The standard audio player is nothing particularly remarkable, from sound settings There is only a standard equalizer with several preset values.

Camera

Cat B15 is equipped, like most modern smartphones, with two modules digital cameras. True, the front camera here is equipped only with a very modest VGA module with a resolution of 0.3 megapixels.

The main rear camera is also equipped with a rather modest 5-megapixel module, from which, nevertheless, the image processing program “squeezes” everything it can. By default, the camera shoots at its highest possible resolution of 5 megapixels, and the resulting images are 2560x1920 in size. Examples of photos taken with factory settings and our comments on their quality are presented below.

Quite acceptable resolution. The foliage of the trees in the background begins to clump together, but the camera tries to process it.

The same effect on tree crowns. In the lower right corner the resolution drops a little, but overall the image is very decent, even in the farthest plans.

The foliage is done well, but it feels like it's been painted on.

The exposition is not bad. Noise in the shadows is very moderate.

In distant plans, the clarity of large objects is decent, and finely detailed ones seem to be painted.

Again the same effect of small objects sticking together, but large ones with good sharpness.

Noises in the shadows are barely noticeable.

Small font distinguishable, which, of course, is not so surprising, but good.

The macro is nice and detailed, there's even a hint of bokeh.

The text is intact, but it looks like the font has been smoothed out.

The camera is nice and quite reasonable. It fully utilizes its 5 megapixels.

In many photographs you can notice overly smooth and uniform transitions between shades. The camera processes in a very interesting way what it sees poorly due to its limited capabilities. The program seems to be finishing the landscape with oil. Of course, this is a minus from a documentary point of view, but from an artistic point of view it is a very interesting phenomenon. The program simply paints a picture from life itself. And it should be noted that she does it well. The transitions from sharp to unsharp zones look quite smooth.

The camera copes well with noise, trying to shoot at minimum sensitivity values. For example, the photo with the yellow box uses ISO 103, and this is the only photo in this series in which the sensitivity value is not around ISO 50.

This camera copes well with both artistic and documentary photography. Of course, for a documentary it does not have a very high resolution, but software processing sometimes adds “artisticness” to the photographs.

The camera can shoot video, and even has the opportunity to “try” itself in Full HD shooting, but it does this poorly: the image turns out slow and jagged, so the system frankly cannot cope with shooting at maximum resolution. By default, the camera shoots video only in 640x480 resolution. However, we tried shooting in both modes; examples of videos are presented below. Videos are saved in a 3GP container (video - MPEG-4 Visual (Advanced Simple@L5), sound - AAC LC, 128 Kbps, 16 kHz, 2 channels).

  • Video No. 1 (13.4 MB, 640×480)
  • Video No. 2 (8.65 MB, 640×480)
  • Video No. 3 (31.2 MB, 1920×1088)

Camera control settings are standard for Android systems: Not the most successful layout of the icons forces you to scour the menu. Selecting options, such as shooting resolution, is done by clicking on the small arrows to the right and left, which is very inconvenient. In general, manufacturers are doing the right thing by modifying the standard Google interface. However, the possibilities for managing shooting are quite rich: you can add geotags and artistic effects, and color effects, adjust white balance, saturation, brightness, contrast, and even enable HDR mode.

Shooting, as already described above, can be done by pressing virtual button on the screen and on the hardware mechanical key on the side of the device. This key is not capable of activating the camera from a locked state, such as Sony smartphones. But you can take photos directly while shooting a video, which can be useful.

Telephone and communications

The smartphone works as standard in modern 2G GSM and 3G WCDMA networks; There is no support for fourth generation networks (LTE). At all, networking opportunities smartphones today are minimal: the 5 GHz Wi-Fi range is not supported, and there is no support for NFC technology either.

There were no freezes or spontaneous reboots/shutdowns observed during testing. When you bring it to your ear, the screen is blocked by the proximity sensor. The light sensor controls the screen brightness level automatically. But, unfortunately, they didn’t provide any warning light sensor here, which is a pity.

OS and software

There's not much to talk about in this section. The system is used software platform Google Android version 4.1.2 and its proprietary interface. The developer did not use any additional graphical user interfaces of his own production, nor can you find any additional pre-installed ones here. third party applications. Everything remained as it was intended by the creator of the system - only “bare” Android and a few icons-links to the Internet pages of various online services of Caterpillar itself (for example, rental construction equipment). But of course, nothing prevents the user from downloading and installing any programs available in the Google Play online store.

Performance

The Cat B15 hardware platform is based on the MediaTek MT6577 single-chip system (SoC). CPU it has 2 Cortex-A9 cores operating at 1 GHz. It is assisted in processing graphics by the GPU PowerVR SGX 531 video processor. The device has only 512 MB of RAM, which is not enough for an Android system. Storage, accessible to the user For loading own files, initially amounts to about a gigabyte of the nominally designated 4 GB internal memory, but it is possible to expand the memory using microSD cards. Connection mode external devices to a USB port (USB Host, USB OTG) is not supported here.

Based on the data obtained during testing, the performance of the Cat B15 was at the expected low level. There is no discovery in this: exactly the same numbers were obtained as a result of tests by the Lenovo A660, which operates on a similar hardware platform. By the way, the results for a secure Samsung smartphone are similar.

As for testing the graphics subsystem in the cross-platform 3DMark test, neither the Lenovo A660 nor our today’s “ward” clearly failed. The phones simply couldn't pass the test, throwing up failure messages on the screen. In principle, this is understandable: the test itself is very difficult, and both devices do not officially meet its requirements - at least with regard to the amount of RAM.

IN gaming test Epic Citadel results for the Cat B15 graphics subsystem are modest, but at least testing passed without failures.

As for benchmarks for assessing the speed of the javascript engine, the results depend significantly on the browser in which they are launched, so the comparison can only be truly accurate on the same OS and browsers, and this is not always possible. In the case of devices running on the latest operating system Android versions, we always try to use Google Chrome.

Playing video

To test omnivorousness when playing video (including support for various codecs, containers and special features, for example 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 options using processor cores alone. Also, don't expect mobile device decoding everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it.

Battery life

The capacity of the battery installed in the Cat B15 is 2000 mAh. The battery here, as already mentioned, is removable, so it can be removed and replaced (battery brand B10-2).

Continuous reading in the FBReader program (with a standard, light theme) at a minimum comfortable brightness level (brightness was set to 100 cd/m²) lasted 14 hours 15 minutes until the battery was completely discharged, and continuous viewing of videos from YouTube in high quality(HQ) with the same brightness level via home Wi-Fi network The device spent more than 7 hours - not bad performance, but this is normal for a small screen with low resolution and dim backlighting. The Lenovo A660 performed worse, which is consistent with its smaller battery capacity.

Bottom line

Officially, Caterpillar does not supply its smartphones to the Russian market, and Cat B15 can be purchased abroad at prices starting at 300 euros. If you search in online stores, then in our country the few sellers that offer this model set prices for it from 21 to 25 thousand rubles. Of course, the smartphone turns out to be very expensive for such primitive characteristics: for that kind of money you can buy two uncertified Sony Xperia V (≈11 thousand rubles) or as many as three Lenovo A660 (≈7 thousand rubles), and in terms of protection from dust and water, these models are basically equal to each other. But if you are faced with the task of choosing a truly protected smartphone model that is not afraid of falls from heights or impacts against rocks, then you can probably overpay. However, it is better, of course, to try to order a Cat B15 from abroad, on Amazon for example: it will be much cheaper, even taking into account delivery.
