New for spring 2018, Asus ZenFone Live L1 G552KL LTE Dual SIM black became the brand’s first smartphone that was produced using Android program Go. Light version of OS Android Oreo and the built-in services in it are specially optimized for budget stuffing.
Big screen without compromise
If most manufacturers budget models trying to save on screen dimensions, Asus in its ZenFone Live L1 model decided not to limit the user in the convenience of managing applications. The smartphone is equipped with a large 5.5-inch screen with HD+ resolution, which provides excellent color reproduction and high contrast even at wide viewing angles. ZenFone Live L1 will become a real pocket cinema for you!
Limitless memory – limitless possibilities
The heart of the smartphone is the popular Snapdragon 425 chipset with 4 cores, a clock speed of 1.4 GHz and a capacity random access memory in 1 GB. By optimizing software and hardware, even heavy-duty applications run on the phone without lags or freezes.
A separate feature of the chipset is that it provides for the layout of the gadget with slots for the largest memory cards. Yes, there is only 16 GB of built-in memory, but internal storage can it be expanded to... 128? 256? No – for as much as 2 TB! So in one smartphone you can store all the seasons of your favorite TV series and still have space left.
When every frame matters
The Android smartphone ZenFone Live L1 has very impressive cameras for its price category. The main 8 MP photo module produces decent images even in low light, and also supports shooting modes such as HDR, Time lapse, Slow-Mo and panorama.
The 5MP smart front camera is used for face unlocking and also contains various beauty filters to create the most stunning selfies.
Not budget autonomy at all
Optimization in the smartphone clearly benefited the battery. With a capacity of only 3000 mAh, Asus ZenFone Live L1 G552KL LTE Dual sim black is capable of working for more than 1000 hours in standby mode. The smartphone will be appreciated by those who like to plunge headlong into the Internet space - in Wi-Fi mode the gadget works for up to 18 hours. And avid music lovers will be able to listen to their favorite tracks for 96 hours without interruption!

Our today's “patient” is a new smartphone, a representative of the third series of “zenfones” - ASUS Zenfone 3 (ZE552KL). This series includes several more models, from the long-lasting Zenfone 3 Max to the “luxury” Zenfone 3 Delux.
Our patient does not belong to the “extremes”, he is the most classic “Zenfon”, intended for a wide range of users who need a good “station wagon” at a reasonable price.
Compared to its predecessor, Zenfone 2 , from Zenfone 3 There have been major changes in both the design and the platform.
In terms of design, ASUS abandoned the volume rocker located on the rear panel and returned it to side edge- a familiar place for most users.
And in terms of the platform, ASUS abandoned the Inlel processor in favor of one of the market leaders - Qualcomm.
Main technical characteristics of the phoneand ASUS Zenfone 3 (ZE552KL) - inthis table:
| Processor (SoC) | Qualcomm Snapdragon 6 25, 8 x 2.0 GHz, Cortex-A53, 64 bit |
| GPU | Adreno 506 (built into processor) |
| Flash memory | 64 GB (there is a modification with 32 GB) |
| RAM | 4 GB |
| Display (size, type, resolution) | 5.5", IPS, 1920x1080 (Full HD), OGS |
| Cameras | Main: 1 6 MP (autofocus, flash); front: 8 MP |
| SIM cards | 2 (nano-SIM + micro-SIM), alternating operation |
| Micro SD card slot | Yes (combined with SIM) |
| Data transfer | GPRS/EDGE/3G/HSPA+/4G; Wi-Fi 802.11b/g/n/ac; Bluetooth 4.2 |
| Battery | 3000 mAh (non-removable) |
| Navigation | GPS/GLONASS/BDS |
| Additional functions | FM radio, fingerprint scanner |
| Dimensions |
152.6 x 77.4 x 7.7 mm |
| Weight | 155 g |
| Official site | ASUS |
The smartphone is in the upper middle range in terms of performance. class a.
But ASUS is not trying to promote Zenfone 3 to flagships in terms of performance, which, according to by and large, few users need them.
ASUS positions this smartphone as “created for photography,” which is confirmed by the technical data of the camera: high resolution (16 megapixels), electronic and optical stabilization, video recording in 3840x2160 (4K) format, autofocus laser sight. And this is really useful for almost all users, since few people refuse the temptation to use their phone as a camera.
The device has a wide range of sensors: sensor automatic adjustment brightness, orientation sensor (G-sensor) and proximity sensor ( this trinity available almost everywhere now) as well as a magnetometer, which is the basis electronic compasses; and even a step counter (pedometer).
Also present in the device traditional vibration motor and LED indicator.
There is also such a fashionable thing as a fingerprint scanner.
The smartphone is available in different colors; the white one came to our “operating table” (and there are also gold, black, turquoise).
Packaging and equipment
The packaging of the smartphone is made in the form of a modest box with a hinged lid:
Let's see what equipment comes with it. First - “charging” (charger):
The included “charger” is somewhat more powerful than what is usually applied to smartphones. Its parameters: 5 Volts, 2 Amperes. "Fast charging" is not supported.
And now - the cable. And our cable is not simple, but with a USB Type-C connector:
Due to the presence of the USB Type-C connector, two news emerge: one, as usual, is good; and the other is bad.
The good news: the connector is symmetrical and can be connected in any direction.
The bad news: such cables are still “a novelty” and are rarely found on sale.
The headphones come with a small bag containing two pairs of spare tips (photo not shown).
Also included warranty card and "a short course for a young fighter" ("user's manual"):
There is also a tool for removing the tray with SIM cards and a memory card (not shown in the photo); if lost, it can be replaced with a paper clip with a bent end.
The equipment is therefore quite standard. As always, the USB OTG adapter cable is forgotten; and here it would be especially useful due to the low prevalence of such a product for USB Type-C connectors.
Appearance, design software ASUS smartphone Zenfone 3 (ZE552KL)
On the front side, the smartphone has a conventional layout:
All the required elements are in place, only the indicator LED is not visible. It is hidden behind the front panel and becomes visible only when it signals an event. It can signal in two colors (red and green) and two types of light (continuous and flashing).
For example, this is how this LED indicates the successful completion of charging:
The image on the display, as can be seen in the photographs above, does not reach its edge, forming a small black frame (about one millimeter wide).
Touch buttons located under the screen are not backlit. And I think that's right. Now I'll tell you why.
There are many smartphones in which the backlight of the buttons lights up after touching at least one of them. And here is a question for their manufacturers: what is the use of the backlight if it lights up AFTER touching the button? Where is the logic?
The only exception seems to be SONY smartphones, where the backlight is always on when the screen is on.
In our “patient”, after some time of getting used to it, you begin to press the buttons correctly even in complete darkness, there are no problems with adapting to this.
Diagonal view from left-bottom-rear:
On the bottom edge, in addition to the microphone, there is a USB Type-C connector for charging and for connecting to a computer, as well as connecting flash drives and other devices via a USB OTG adapter cable (not included, you need to buy it separately, it’s still difficult to find).
The ringing speaker is also located on the bottom edge. This location is correct, since it will not be muffled, no matter which side you place the smartphone on the table. But it’s a pity that he is the only one, i.e. there is no pair for it to provide stereo sound when listening to music and watching movies.
On the left side there is a tray for SIM cards and a memory card (hardly visible in the photo, because it does not stand out in color and merges with the edge).
The tray is of a combined type, i.e. You cannot fit two SIM cards and a memory card into it at the same time. You can either have a memory card and one SIM, or two SIMs. The last option will apparently be more relevant due to the large volume own memory smartphone.
And the tray looks like this:
Now - a view of the smartphone from the opposite diagonal (right-top-back):
On the top edge (it's here at the bottom left) there is a hole for the second microphone and a 3.5 mm jack for a headset or headphones.
On the right side (it's really on the right here) there is a volume rocker and a button to turn on-off-airplane mode.
The back panel here is extremely interesting.
First of all, it is glass! It’s difficult to say anything about its fragility or strength (the SmartPulse portal does not conduct lethal tests), but its resistance to scratches is the maximum of all possible. While scratching the surface of metal or plastic is easy, scratching glass is very difficult.
Also in this photo you can clearly see the main camera with its inherent flash and laser autofocus.
Protective glass camera is raised above the surface of the back panel. This means that the camera is large, and therefore good. They have this property - the better the camera, the larger it is.
To the left of the camera (in the photo) is a built-in flash. Is there any physical meaning- It’s hard to say, but the flash shines very brightly.
And to the right of the camera in the same photo is a dark window for infrared laser autofocus. The camera “catches” focus really well and quickly. But autofocus performance cannot be called completely flawless: a small percentage of shots with a focus error still happen.
Also on the back panel there is a fingerprint scanner in the form of an oblong rectangle with rounded corners. His work is truly impeccable. You just need to scan the fingerprint correctly initially, slightly changing the position of your finger each time you touch it to the sensor (the smartphone asks you to touch it about 7-10 times).
Now let's move on from appearance to software.
First, let's study the list of applications installed by the manufacturer using the corresponding screenshots. There will be 4 of them:
Pre-installed applications- so many. But due to the large amount of memory in the device, the task of dealing with them is not particularly acute.
By the way, the operating system here runs under Asus’ own shell called ZenUI. The shell allows you to group applications into groups and has many other useful features. Works fast.
Display
The smartphone display has a Full HD resolution - 1920 x1080. Screen size - 5.5 inches; pixel density - 401 per inch (very high).
The display is made using OG technologyS (One Glass Solution). This technology ensures that there is no air gap between the touch surface and the screen, which halves the number of reflective layers and, accordingly, reduces the level of glare when working in conditions of strong external lighting.
The uniformity of brightness between white and black screens is excellent, without "spots".
The measurement results of technical parameters are shown in the following table (display settings are “default”):
The brightness adjustment range is sufficient to work in any external conditions- from bright sun to complete darkness.
The color temperature (8000K) turned out to be higher than the standard (6500K), which gives image light"cool" shade. If desired, you can correct it using the built-in color adjustment utility called " Splendid".
Contrast is well above 1000. This is an excellent level, comfortable for viewing the entire spectrum of images.
The color gamut is close to the sRGB standard, deviations are not significant:
The sense of touch is excellent: the display recognizes up to 10 simultaneous touches. Touch sensitivity is very good; and can be additionally increased by enabling the “glove” mode. But the gloves should not be too thick.
Platform and performance of the ASUS Zenfone 3 (ZE552KL) smartphone
In smartphone e ASUS Zenfone 3 (ZE552KL) uses a 64-bit processor (SoC) Qualcomm Snapdragon 625, 8 cores x 2 GHz, Cortex-A53. Distinctive feature processor - in new production technological process with standards of 14 nm. Previously, most processors for smartphones were manufactured at 22 and 28 nm standards.
Reducing the size of transistors and other elements of the microcircuit entails many advantages, from reduced power consumption to the possibility of increasing clock frequency and speed. But in our processor, judging by its fairly normal frequency (2 GHz), the main benefit should come from reducing power consumption.
Our patient has 4 GB of RAM, which is a lot, flagship-grade.
First, let's take an X-ray of the patient's insides. We will use the well-known AnTuTu benchmark as an x-ray: it will show the “inside” and evaluate the performance.
Here are the long-awaited results of smartphone performance testingon ASUS Zenfone 3 (ZE552KL) in AnTuTu:
In total, the result of the antutu test for the ASUS Zenfone 3 (ZE552KL) smartphone was 62622 points and a conditional 35th place. If we focus only on performance, we have a “golden mean”, but we are far from flagships. But performance is far from the only parameter by which devices are evaluated.
Let's run a little more in other "running" tests.
Geekbench:
Epic Citadel, minimum quality settings:
The result is good, but “ideally” the performance should be not 50, but 60 fps.
Now - the same Epic Citadel, but at maximum quality settings:
For maximum quality settings, the result is very good.
Then - 3 DMark in the "Ice Storm Extreme" version:
And one more thing - Basemark X:
And finally, the popular complex test Vellamo in its three guises:
What conclusions should be drawn from these tests?
Firstly, performance- at a good average level; one might even say above average. General civil applications will work without any questions. Interface slowdowns, etc. not noticed.
Secondly, in 3D games there may be questions, but only in the most difficult of them. Use lightweight settings whenever possible.
Let's move on to flash memory.
To analyze the memory situation, we only need one screenshot from the built-in file manager:
In this screenshot we see the state of three types of memory: internal smartphone storage, inserted 64 GB microSD memory card and connected via a USB OTG adapter cable to a 4 GB flash drive (USB storage).
Internal memory out of 64 GB, 52.66 GB is available to the user. This is a very decent value, and for most users it can close the question of expanding memory forever (since it is not required).
For geeks who find this amount of memory not enough, you can add a microSD memory card. The smartphone recognized a 64 GB card, and will be able to recognize more! There is only one “but” here: the memory card slot is combined with a SIM card, and if you use a memory card, you will not be able to install a second SIM card.
To connect external storage “temporarily” you can use standard USB flash drives. The smartphone recognizes flash drives with a capacity of up to 32 GB inclusive.
The USB-OTG adapter cable for the USB Type-C port looks like this (not included, purchased separately):
Please do not confuse this adapter with a standard OTG adapter with a micro-USB connector on the “thin” end - it is in no way compatible with USB Type-C!
Multimedia (sound and video)
The smartphone has a standard sound design: a monaural ringing speaker and a headphone output in the form of a standard 3.5 mm jack. Innovations from the latest trends in the spirit of smartphones without a standard headphone output, thank God, have not been applied.
Bass in the sound of the built-in speaker, as usual, is poorly represented, high and mid frequencies are normal. Volume level is good. Even quiet tracks in films can be “boosted” by adjusting the volume to a comfortable level.
In headphones (if they are medium or high level) you can hear even more high quality sound. There are no problems with the frequency range, noise does not get through. And the volume, similar to the built-in speaker, has a large margin of adjustment.
Playing video with the built-in player runs into a traditional problem: AC3 encoded audio does not play. But not only does the sound not play, it doesn’t even show the picture. We managed to “cure” this problem in the usual way - by installing a third-party player. True, I had to go through several pieces before I found the right one.
Both standard and “large-sized” video formats (up to 3,840x2160 @30 fps inclusive) were played back without problems, which is quite natural: if a smartphone can record 4K video (3,840x2160), then it should be able to play it back!
We assess the level of multimedia in our patient as excellent.
Communication and navigation
The smartphone uses 4th generation (4G) communications. Its performance is confirmed not only by the appearance of the “4G” icon in the top line of the screen, but also by the really high data transfer speed.
The OOKLA Speedtest application showed the following average speed value:
These numbers, of course, are simply confirmation of the functionality of the 4G Internet channel (LTE). Real speed in different areas and areas different operators can be very different.
Other types of wireless communications - Wi-Fi and Bluetooth - worked without problems, as is usually the case. But NFC did not work, because... It’s simply not there, unfortunately.
Navigation system smartphone during a “cold” start was completed in a very short time - less than a minute, and during “hot” starts - in a few seconds.
The launch of the AndroidTS navigation testing application showed that the smartphone supports three navigation systems - imperialist GPS, domestic GLONASS and native Chinese BDS (Beidou). In Russia Chinese system, perhaps in the future it will be of interest to residents of the Far East and the Baikal region.
Test track recording in difficult conditions(in the forest) showed that even in such conditions the accuracy is sufficient for high-quality navigation:
We rate the navigation as excellent.
Battery
The battery capacity of the smartphone is exactly 3000 mAh, which is exactly what is currently accepted for smartphones with a 5.5-inch screen.
A circumstance that can prolong the autonomous life of the device can be the use of a processor based on the latest 14-nm technological process. The smaller the transistor, the less current it consumes, all other things being equal. But, of course, saving energy in the processor will not in any way affect its consumption for the screen backlight. In this regard, the increase in autonomy should be noticeable, but not to the same extent as the decrease in processor consumption.
In “heavy” load mode (AnTuTu battery test), the smartphone lasted just over 5 hours; and when watching movies - over 11 hours. These results significantly exceed the average level.
Let's look at the graph of the battery condition in the "discharge - pause - charge" mode. The discharge was carried out by the utility for testing batteries "AnTuTu Tester", the charge was carried out from the USB port of the computer.
Under heavy load, the smartphone warmed up slightly, up to 37.5 degrees (according to battery temperature, at an external temperature of 23C):
Logically, everything fits: since it consumes less energy, it also heats up less.
Charging the phone from the USB port after discharge takes about 5 hours, and from the charger - about 3 hours. These values are within the standard range for smartphones without fast charging support.
Thus, we ultimately evaluate the autonomy of the device at a very positive level.
Cameras
The smartphone uses a 16-megapixel main (rear) cameracamera with laser autofocus and flash and 8-megapixel front camera with fixed focus.
The manufacturer specifically mentions in the smartphone advertisement that it is “created for photography.” If so, then now we will test it “to the fullest extent”!
We start testing with the main (rear) camera. Attention! By clicking on the photo they will open in a new window in full size, file size up to 7 MB!

A brief summary of a series of test photos and videos.
The quality of photos and videos on our smartphone is very high (among mobile devices). The manufacturer’s words that it was “created for photography” turned out to be completely confirmed.
With this, we consider the consultation of doctors complete and move on to the results.
Final diagnosis of the ASUS Zenfone 3 (ZE552KL) smartphone
The smartphone turned out to be interesting, especially in terms of photo and video functions. This is its main advantage, although there are others.
I was very pleased with the length battery life, the quality of communication and even the material from which it is made - glass. This promises good resistance to scratches and other minor troubles that fate has in store for our travel devices.
However, dropping it is highly not recommended. Remember that ANY glass can be broken, even if it is “Gorilla” at least four times. And even in the glass of airplane windows, cracks are sometimes found (God forbid, of course!).
Among the shortcomings, we note the lack of NFC near-field communication, which was present in the predecessor (Zenfone 2), but disappeared somewhere in our “patient”.
The final diagnosis is this.
pros:
Good screen with correct color rendering and high brightness;
Good wireless communication, 4G (LTE) support;
Great quality photo and video, video shooting in 4K format (3840x2160);
Processor performance sufficient for most tasks;
High amount of RAM and flash memory;
Availability of a slot for an external memory card;
Supports two SIM cards;
Good quality of sound and video playback;
High quality navigation;
USB-OTG support;
High quality fingerprint scanner;
Good autonomy.
Minuses:
Lack of NFC near field communication;
Built-in video player does not support AC3 audio, installation required external application;
Combined slot for SIM cards and memory cards (you can’t use everything at the same time).
Check for system updates, if there are any, install them.

For three years now, ASUS has been releasing smartphones from the popular Zenfone line. At first these were inexpensive plastic models that blew up the market. The second generation Zenfone has already approached the mid-price segment and has received many technical goodies. What did Zenfone 3 become? Let's watch.
Releasing flagships made of plastic in 2016 is a complete disgrace. ASUS followed the general trend and made Zenfone 3 (ZE552KL) from glass and metal. Externally, a smartphone looks a bit like Samsung Galaxy Note7, however, the decision to make a fingerprint scanner for unlocking on the rear panel makes the device similar to the Chinese.
Overall, the ASUS Zenfone 3 (ZE552KL) is certainly beautiful. It looks expensive, feels monolithic, attracts attention - in general, aesthetically it is not inferior to more expensive devices. Only time and crash tests will tell how durable and practical the smartphone is. ASUS has used Gorilla Glass 3, which means the smartphone is scratch-resistant, but the front and back panels may crack if dropped severely.
The brightness range is wide enough for comfortable use of the smartphone at night, when the screen needs to be dimmed as much as possible, and in bright conditions. sunlight, when for good readability it is necessary to “raise” the brightness higher. There is a filter in the settings of blue color, which makes the image warmer and more pleasing to the eye, which is important when reading. In general, no complaints.
Performance
Although the design of ASUS Zenfone 3 (ZE552KL) is made at the flagship level, technically the smartphone represents an army of mid-rangers. It is based on an eight-core Qualcomm Snapdragon 625 chipset with an Adreno 506 graphics coprocessor. In general, this system-on-chip will even allow you to play, albeit at maximum graphics settings. latest games will not be available to you.
RAM capacity is 4 GB, built-in memory is 64 GB. There is support for memory cards, but you will be faced with a choice: either a flash drive or a second SIM card. Considering the mentioned 64 GB, which is enough for most of us, it will not be difficult to choose.
The camera has become almost the main element of a smartphone, and if everything in terms of “filling” is extremely rare to see something special, unless we are talking about flagships, then with cameras it’s a completely different matter.
Zenfone 3 (ZE552KL) has a camera packed with advanced technologies to the limit. It is built on a Sony IMX298 photo module with a resolution of 16 megapixels and an f/2.0 aperture. The optics consists of six elements, and therefore provides good images even in difficult lighting conditions and when shooting contrasting scenes. The lens is protected by scratch-resistant sapphire crystal, which is used in the watch industry. The optical image stabilizer is responsible for sharpness when shooting on the move and at long shutter speeds in low light.
And, of course, ASUS Zenfone 3 (ZE552KL) has a triple TriTech AF autofocus system, which combines conventional contrast autofocus with fast phase detection, as in DSLRs, and laser. The latter operates at a distance of up to 1.2 m and is especially helpful when shooting moving objects and in the dark. The TriTech AF system takes just 0.03 seconds to focus on a subject, claims ASUS. Yes, Zenfone 3 really “catches” objects very quickly and accurately.
By the way, thanks Qualcomm processor The Snapdragon 625 camera of the Zenfone 3 (ZE552KL) is capable of shooting 4K video.
The first feature of Zenfone 3 (ZE552KL) support LTE networks Cat.7 - the smartphone is capable of downloading data at speeds up to 300 Mbit/s and transferring data at speeds up to 100 Mbit/s. However, in real life you won’t be able to get such numbers.
The second feature is the presence NFC chip, which will allow you to connect other devices to your smartphone with one touch, check the balance of transport cards, and pay for the metro.
The third feature is support for two SIM cards of different formats. One slot for nanoSIM card, the other is for microSIM. As with many other devices, you will have to choose between a second SIM card and a microSD flash drive, since both are installed in the same slot.
Working hours
Zenfone 3 (ZE552KL) pleased us with its energy efficiency. Although the 3000 mAh battery is standard for smartphones with such a screen, it lasts for one and a half to two days of battery life in a mixed cycle. The smartphone is charged to 100% in 2 hours. And by the way, like many other manufacturers, ASUS switched to Zenfone 3 (ZE552KL) USB port Type-C – the plug can be inserted into it from either side.
Software
The device operates under operating control Android systems 6.0 Marshmallow with branded shell ZenUI. If ASUS follows trends in terms of material and design, then in terms of user interfaces– is somewhat behind.
