LeTV One (Le1, X600, S1) review of an elegant smartphone powered by Helio X10 (MT6795) chip

25.06.2015 46361 16

Many of you have already seen our video review of one of the most intriguing smartphones in the first half of 2015 - LeTV One. The same smartphone is known under the code name LeTV X600, and in the domestic market - as LeTV S1 or LeTV Le1.

Despite the fact that this is the first experience for LeTV in the production of smartphones, the new LeTV One immediately attracted attention. There are two reasons for this: for starters, this is the first device that has long been considered frameless, judging by the numerous teasers and spy photos. And secondly, this is the first announced smartphone based on the Helio X10 (MT6795) processor, which is currently the most powerful in the MediaTek lineup.


And, despite the fact that the frames at the edges of the screen on LeTV One turned out to be quite ordinary, the smartphone still attracts us with its interesting design, high-quality materials, as well as powerful and rich hardware stuffing.

In this article, we will talk a little more about the LeTV One smartphone and try to reveal some of the points left behind the scenes of our video review. And we will start, as usual, with a description of the packaging, equipment and appearance of this device.

Overview of the configuration and appearance of LeTV One (Le1, X600, S1)

The smartphone comes in a compact branded white packaging. On the inscription box itself, you will find only the manufacturer's logos and a list of the characteristics of our device on the reverse side.

Under the cover of the packaging in the top tray, you will find the device itself, which is wearing a branded silicone bumper case. The display of the smartphone is sealed with a transport protective film, and the main camera eye is also sealed with a film.

Further, in the same tray, you will find an envelope from which, on one side, you can pull out a cardboard tab with a paperclip to remove the SIM card tray, and on the other side, you can find the instruction manual in Chinese and the warranty card. All this is done in a very original way and immediately inspires the feeling that we have a really expensive and high-quality product.

After removing the top tray, you will find a charger with a current capacity of 2A. It has a connector in the form of two parallel flat blades of Asian and North American type without grounding. So you will need an adapter to use with our sockets.

Also, under the top tray, next to the charger, you will find a USB cable that is wound around a kind of round spool with a lid. On one side of the cable, the connector has a Type-C standard, and on the other, a regular USB.

The package bundle of LeTV One is not the richest, but everything is decorated very stylishly and soundly, which will still leave you with only positive emotions.

So, once again we list the LeTV One package:


  • Smartphone LeTV One
  • Silicone bumper case
  • Charger with connector type "A" and current capacity 2.0A
  • USB cable for connection to charger or computer
  • Chinese instruction

Let's move on to the appearance of LeTV One (Le1, X600, S1)

The front panel of LeTV One is made of protected glass, the manufacturer of which is not specified. The protective glass is flat, does not have any rounded edges according to the type of 2.5D technology. Thanks to a thin metal frame and a special black coating, when the screen is off, it seems that it has no frames on the left and right, but once you turn on the smartphone, you realize that the screen has rather wide frames. Their width is about 2.6 mm.


At the bottom of the front panel there are 3 standard touch buttons, which are backlit.


At the top of the front panel placed an event indicator, light and proximity sensors, earpiece and front camera eye.


As we have already said, the body of LeTV One has a metal frame. On the left side of the case are the volume control button and the mute switch.


On the right side of the case there is a power button and a slot for two Micro-SIM cards.


On the lower end of the case, you will find a USB Type-C connector in the center and the same slots on both sides of it symmetrically, moreover, behind the one on the left, a conversational microphone was hidden, and behind the second, an external speaker.


And on the upper end of the case there is an infrared port and a standard 3.5 mm audio jack for a headset or headphones.


The back panel of the LeTV One phablet is made of plastic with a glossy finish. With not very careful handling, scratches will appear on it, so the complete bumper case will come in handy.


At the top of the rear panel of the case there is a noise reduction microphone hole, a main camera eye and a dual-color LED flash module.


The back cover of LeTV One is non-removable, so there is no access to the battery. Although this ensured the absence of any squeaks and backlashes in the device case. And the assembly of the smartphone can be called almost standard. The ergonomics of the smartphone is also excellent, although for those who have never used Apple devices, the placement of the volume button will seem unusual.

The front panel has a good oleophobic coating, so there are practically no fingerprints left on it when using a smartphone. However, the presence of a glossy coating on the back of the case, as well as the rather thick device, slightly spoil the impression of the first acquaintance with LeTV One.

And although the device sits well in the hand, without causing any discomfort, the manufacturer should still try to make the case at least 1 mm thinner, especially considering that the battery inside is far from the most capacious one. It also made sense to think about a more practical rear panel cover. Even applying some texture would make it better in this regard. Thus, we cannot give the maximum rating for the appearance of the LeTV One phablet.

The dimensions of the device were 147.5x74.2x9.5 mm, that is, the height and width of LeTV One is more compact than many other smartphones with the same display diagonal. And the weight of our test subject turned out to be quite decent, amounting to 170 grams.

Let's move on to the technical part of the device, starting, as usual, with the display.

LeTV One display review

The display diagonal is 5.5 inches, which puts it in the class of phablets. The display has a resolution of Full HD, i.e. 1920x1080 pixels.

In the manufacture of the display, an IPS-matrix manufactured by Sharp was used. There is no air gap between the glass and the matrix, since they are made as a single whole using the so-called OGS technology. Viewing angles of the display are very wide, color reproduction and brightness are excellent, which is a traditional hallmark of this manufacturer's displays.

MultiTouch test showed a high result of 10 points of simultaneous touches, corresponding to the screens of flagship smartphones.


Let's get to know the interface.

Overview of interface and software platform LeTV One (Le1, X600, S1)

The LeTV One phablet runs on the Android 5.0 Lollipop operating system with a pre-installed proprietary shell from the EUI 5 manufacturer. Once again, I would like to note the excellent picture quality on the screen, as well as its high speed of response to touch.


Thanks to the proprietary shell, the interface in the smartphone cannot be called standard. The touch button on the far left brings up a menu for quickly activating various functions, such as turning on WiFi, GPS, flight mode or flashlight, launching a calculator, controlling image rotation lock, controlling a music player, and others.

In the stock version of Android 5.0 Lollipop, you would have to double-swipe down from the status bar to get to these features, but here everything is much simpler. Also, by pressing the far left touch button, we get access to active applications that can be closed with the usual swipe from the bottom up, as in the IOS operating system.

The rightmost touch button performs the "back" function. And with a long press on the "Home" button, the voice assistant is activated. But it will be useful to you only if you know Chinese.

In general, the interface is really convenient and has nothing superfluous, except for some built-in Chinese services. Difficulties will arise only for those who do not know English well, since the manufacturer does not have an official firmware with support for the Russian language and is not planned. However, many stores already offer a custom version of the firmware in the LeTV One they sell, where the Russian language will be present. We also ordered one of these copies for future comparison.

Let's go to the phone settings menu. Here it should be noted the presence of the OTA wireless update function, which works flawlessly in our version of the device. During testing, we were able to download and install the latest official firmware using this function. However, those who purchase a device with a custom firmware version should not count on using this feature.

In the display settings menu, you will find the ability to customize the operation of the event indicator to your preferences. However, in the settings menu, we did not find any function for data transfer, except for Bluetooth, since there is no support for NFC and HotKnot here.

Be sure to note the presence of an infrared port settings menu. In the process of testing, we did not have any difficulties with setting up a device to control equipment. We successfully managed to set up the control of the air conditioner and TV in our studio using the infrared port built into the LeTV One. A very handy and useful feature.

There are some other minor changes in the interface from the standard version of Android 5.0 Lollipop, but they are all intuitive and we will not dwell on them in detail. Otherwise, the version of the operating system to which we are already accustomed is quite recognizable.

Next, let's see how LeTV One performs with its powerful Helio X10 processor and PowerVR G6200 graphics chip when tested in various benchmarks.

Performance testing and other benchmarks

We list all the characteristics of the device that affect the results in these tests. Let us remind you once again that the LeTV One phablet runs on the Android 5.0 Lollipop operating system with a proprietary EUI 5 shell. The device has the most powerful MediaTek processor at the moment called Helio X10 (MT6795), operating in our copy at a frequency of 1.95 GHz. The powerful graphics coprocessor PowerVR Rogue G6200 is responsible for the graphics in the system.

The LeTV One display diagonal is 5.5 inches, and its resolution is 1920x1080 pixels. The amount of RAM in the phablet is 3 GB, and the built-in memory is 16 GB, of which a little more than 11 GB is available to the user. There is no slot for memory cards in LeTV One, so the user will have to be content with the remaining amount of internal memory.

In the Antutu v5.7.1 test, the LeTV One phablet scored just over 49,000 points.

In some youtube reviews, you could see the result of more than 50 thousand. But it should be recalled that the AnTuTu test is synthetic, and the absolute result shown in it should not be taken literally. Although the potential of the Helio X10 processor at the maximum operating frequency of the cores is estimated at more than 52 thousand points.

Let's move on to testing the graphics. In the 3DMark test in Extreme mode for Full HD resolution, our copy showed at first a rather modest result for this video chip of 6166 points, but the repeated test put everything in its place, since this time the device gave out almost 10.5 thousand points.

It is worth noting that when testing in 3DMark, and then in the AnTuTu Battery Test, our copy of LeTV One got quite noticeably warm. And this despite the fact that the frequency of the processor cores is reduced compared to the maximum possible. Apparently, excessive heating is a problem not only for Qualcomm processors, but also inherent in MediaTek chips. So, with prolonged use of the LeTV One phablet in games, you will have to experience some discomfort from the heating of the case and take forced breaks in order to avoid discomfort and a possible shutdown of the device.

Built-in sensors and GPS testing (see video for details)

Let's check what built-in sensors our experimental LeTV One is equipped with using the Sensor List program. The result showed the presence of the following sensors on board LeTV One: an accelerometer, a magnetic field sensor, a gyroscope, an orientation sensor, a gravity sensor, linear acceleration and vector rotation sensors, as well as light and proximity sensors. As you can see, the equipment of the LeTV One phablet with sensors turned out to be at a high level.

And now let's check the operation of GPS navigation in our LeTV One. As it turned out, after a cold start and without a WiFi connection, our device connected to the satellites almost instantly. In addition, LeTV One finds GLONASS satellites and connects to them willingly. Thus, you will have absolutely no problems with GPS navigation in this device.

Next, we will talk about the built-in cameras in LeTV One and check their operation.

Testing cameras LeTV One (Le1, X600, S1)

According to the manufacturer, the main camera module in LeTV One uses the IMX214 Exmor RS sensor from Sony. This is exactly the same sensor as in the Elephone P7000, as well as in Ulefone Be Touch, in which, we believe, he could not reveal his full potential.

The LeTV One phablet is also equipped with a dual dual-color LED flash, which should have a positive effect on pictures in low light conditions or at night at close distances to the subject or in macro mode.

The camera interface in LeTV One is also non-standard. In the camera menu, 4 shooting modes are available to us: photography, video shooting, slow motion video shooting and panorama mode. In the photography settings, you will find the HDR function, night shooting, timer shooting, the ability to adjust the exposure, geotagging, and other standard functions. You can also choose the photo size, with the maximum being limited to 13 megapixels.

In the video settings, you can also select the shooting resolution, the maximum size of which is 4K (3840x2160 pixels).

The test shots we took with the main camera were a pleasant surprise. Photos are highly detailed and excellent color reproduction. The depth of field when shooting single subjects or objects is simply amazing. Camera focusing is fast and accurate, and shooting in low light and with flash is no problem either. Before us is a vivid example of what kind of pictures a camera with a Sony IMX214 sensor can take with normally optimized software, which was clearly lacking in Elephone P7000 and especially in Ulefone Be Touch .

It will not come as a surprise that this camera also showed itself perfectly when shooting video. The only issue we had was when using the slow motion mode, since in this mode the focus did not always work correctly. But, we think, this moment will soon be fixed in the next firmware.

As for the front camera, a 5 megapixel sensor is used as its module. Its manufacturer is not reported, but the quality of images from this camera is at a decent level. The maximum photo size from the front camera is 2560x1920 pixels, and the video size is Full HD.

Sources of photos and videos can be found here.

Battery test

According to the manufacturer, the battery capacity in LeTV One is 3000 mAh. However, we cannot verify this in any way, since the case cover in this device is non-removable, and the user does not have access to the battery. However, LeTV claims that LG is the manufacturer of the battery, which gives hope for its high quality.

Let's try to check whether the declared capacity corresponds to the real numbers. In the AnTuTu Battery Test, our test subject scored almost 6400 points. For comparison, this is almost 1400 points less than the Elephone P7000 with a 3450 mAh battery. And this suggests that the power consumption in LeTV One is higher, and that the battery built into it will last you a whole day of use in normal mode.

However, you will certainly be pleased with the fact that the LeTV One charges quite quickly. From the minimum level to 100%, the battery is charged in about 1 hour. This is ensured by a special charger with a current capacity of 2A, which is included with the smartphone, as well as the new USB Type-C port standard. So, you should not have any special problems with autonomy in LeTV One ..


First, let's check the volume of the external speaker. The maximum volume of the LeTV One speaker is quite high, while the sound from the speaker is not distorted, does not wheeze and has good detail. No wonder the manufacturer focuses on this, reporting the presence of a built-in NXP Smart PA TFA 9897 sound amplifier, as well as a high-quality speaker - the sound from the external speaker is really loud and clear.

Let's check the sound quality in the headphones. We are not aware of any separate audio chip in the LeTV One, and most likely it is not here. Most likely, the component integrated into the Helio X10 chipset is responsible for the sound quality here. However, thanks to the competent sound quality adjustment by the company's engineers, as well as the presence of a built-in equalizer with support for Dolby and DTS Stereo formats, the sound in the headphones is excellent. Definitely, the sound in LeTV One is better than in Elephone P7000, Ulefone Be Touch. We met something similar in Lenovo K3 Note , the difference with which can only be noticed when listening to uncompressed audio files and in expensive headphones.

Well, let's sum up the results of our LeTV One testing.


Let's start with the advantages of the device:

1) A good ratio of powerful hardware stuffing and the cost of a smartphone.

2) The presence of a Type-C USB port, which provides higher data throughput, greater power transfer and other advantages, including the ability to connect the cable to either side due to the symmetrical connector design, which is much more convenient than Micro-USB.

3) Fast battery charging. Again thanks to USB Type-C and a 2A charger.

4) Excellent work of the rear camera. The pictures from it are almost as good as in the ZTE Nubia Z9 Mini , although it has a more advanced IMX234 module. Thanks to LeTV engineers who did a great job on the software. If only Elephone and Ulefone did the same…

5) Excellent display. The matrix from Sharp is very good. The colors are juicy, and the margin of brightness is high, so working in direct sunlight will not be a problem at all. It is also possible to fine-tune the display. What else can I say - sheer delight!

6) The presence of an infrared port. For a sub-$300 phone, this should be par for the course, but still, it's a really nice thing to have.

Let's move on to the disadvantages :

1) Glossy back cover. Sooner or later, but scratches will appear on it. So, you have to use a bumper case.

2) The thickness of the body of the device. Especially with a bumper. For a phone with a battery of this capacity, it was quite possible to make the body 1-1.5 mm thinner.

Despite 2 significant shortcomings, we were very pleased with the LeTV One smartphone. Perhaps this is one of the best devices we have tested recently. And at the moment it is the best smartphone in terms of price / quality ratio. What else is there to say? Take it, you won't regret it, especially the version with a large amount of internal memory, which will soon appear on the market!

Совсем незначительно опережает МТК 6752, ожидал большего. Но радует умеренный в сравнении со снапом нагрев. Вообще МТК молодцы, можно сказать на грани обгона квалкома.
