Lenovo S820T: reviews. Overview of Lenovo phones

Relatively recently appeared on sale smartphonethe average price range of Lenovo S820T. Reviews about it come both positive and negative. We will deal with its strengths and weaknesses and determine the feasibility of its purchase on the basis of their ratio.

CPU

Everything was just with the predecessor: 4-core processor MTK 6589 with a frequency of 1.2 GHz was the basis of Lenovo S820. S820T (MTK6592, 8-core CPU, specified in the characteristics of one of the modifications of this smartphone, and MTC6589, integrated in the simplified version of the device) can be equipped with one of these processors, depending on the modification of the gadget: "flagship" or "truncated."

But according to the test results it turns out that instead ofthe first of which is installed MTK6572 with two real cores and six stopped and clocked at 1.3 GHz instead of 1.7 GHz. To verify this, it is enough to download the "CPU - Z" utility from third-party sources and install it. Yes, it really will show after launch that MTK6592 is installed. But here's bad luck - only two cores out of eight work. The rest are in stop mode and can not be started. As a result, it turns out that the processor MTK6572 is integrated into the device. The architecture is the same - "Cortex A7", clock speed - 1.3 GHz and only 2 cores on board. In general, the programmatic trick of the Chinese: you buy one, comes like what you ordered (at least, the software in this convinces), but behind all this is completely different at the hardware level.

The only difference is the presence of externalcommunication module for work in third generation networks. This is the basic configuration of the Lenovo S820T. Reviews of frustrated owners about this smartphone confirm the previously stated dirty trick. But with a 4-core version, everything is fine. Here we use the classic MTC65859T with a frequency of 1.5 GHz. The more cores, the more productive the smartphone, the longer it will last for its hardware resources. Two cores are not enough for comfortable gameplay, but four perfectly cope with this task. A similar situation with resource-intensive applications. Therefore, when buying, you need to specify the actual processor model, which is installed in this device.

Graphic adapter and screen

The screen diagonal of this smartphone is 5 inches. The claimed resolution for the 8-nuclear model is 1920 by 1080 pixels. But with the fact that he only has 2 of them at work, most of the applications will slow down. Do not forget that in this situation, a maximum of two touches will be handled, not five. In turn, the model with CPU MTC 6589 has more modest characteristics - 1280 by 720 pixels and is capable of processing up to five touches inclusive. Type of installed matrix AMOLEED. The picture quality is excellent. But with the graphics adapters, the situation is interesting. In the 8-nuclear version, 450 MPs are programmed from the company "Mali". But in reality, according to the test results, there will be 400 of the same developer for the Lenovo S820T. Characteristics this graphics accelerator is an order of magnitude worse. Again, this adapter usually comes bundled with the central processor MTK 6572 and 512 MB of RAM. Moreover, this is an outdated model for today. But the 4-core version is equipped with a video card SGX544 from the "Powerv". This is a more productive solution that will perfectly cope with most tasks to date.

Memory and its number

An interesting memory situation is obtained from LenovoS820T. Reviews of puzzled owners are superfluous to this confirmation. Let's start with the basic version of this smartphone. The documentation integrates 2 GB of RAM DDR3. But now, after turning on and checking the parameters, an interesting picture is revealed. Yes, its really 2 GB. But the system is constantly strangely borrowing 1.6 GB or more. At best, the user's needs are 200 MB, and maybe even less. In general, again, Chinese programmers cheated. Software designed 2 GB, and in fact installed 512 MB, which are standard for the processor MTK6572. But in the second version with four cores everything is fine, and there is integrated 1 GB. With internal memory, everything is fine. As in the first, and in the second case, its 4 GB, of which 2 GB is occupied by the system, and the rest is provided to the user. There is also a slot for installing flash cards in the format of Micro SD with a maximum capacity of 32 GB.

Housing and ergonomics

The Lenovo S820T is well made. Review of its external components is only confirms. The device itself is a candy bar with touch input support. The diagonal of the screen, as noted earlier, is 5 inches. Under it are three classic buttons: "Back", "Home" and "Menu". And over the screen there is a talking speaker and a camera for making video calls. Covering the front panel - sort of like a protective glass "gorilla eyes", but given the previously stated nuances to believe this is not worth it. Therefore, without a protective film can not do, the good it goes in the kit and in addition there is no need to buy it. The swing volume and the power button are located on the right. Because of this, you can easily manage this device with one hand. Another plus of them - they are made for metal, not so much will get dirty. On the back there is a front camera and a loud speaker. The entire back cover is made of glossy plastic. This is an obvious drawback - a similar coating simply attracts dirt and easily scratches. Again, the kit comes with a leather case, there should be no problems with the safety of the case.

Camera and its capabilities

As noted earlier, the Lenovo cell phoneThis model is equipped with two cameras. One of them on the front of the device is designed to make video calls. According to the documentation it is indicated that it uses a matrix of 1.3 Mp. In reality, this is 0.3 MP. The image quality from her leaves much to be desired. She is hardly suitable for such communication. The second is located on the back of the gadget. It is based on a 13 Mp matrix according to the manufacturer's claims, but in reality this is 8 Mp. Also there is a backlight and autofocus. The quality of the images and video recordings obtained with its help is quite acceptable.

The battery and everything connected with it

Completed Lenovo cell phone of this modela very capacious battery for 2800 milliamp / hour. With a not very high intensity of using this smart phone, its resource is enough for 4 days. This is an excellent indicator for such a device. With more intensive use of battery capacity is enough for 1-2 days. If you listen to music, then one charge will last for 12 hours of battery life. In general, there are no obvious problems here, as with the processor, memory and graphics adapter. Another plus is the ability to replace a faulty battery. It is enough to buy a new battery and open the back cover. Remove the old accessory and install a new one.

OS

Now for the operating system, runningwhich runs Lenovo S820T. The review without it will turn out to be inadequate. Now this gadget runs under "Android" with an outdated version 4.2. In addition, we can say that no updates are expected. That is, all the time this device will only work under the control of this OS. While, of course, compatibility problems do not arise, but after a while they can appear.

Application software

The original set is complete setapplications from "Google" on this model Lenovo. The phone S820T allows you to view videos from "Youtube", communicate in the network "Google +" and correspond with the help of the mail service "M-Mail". "Play Store" is also installed. From here you can easily and easily install other necessary programs. Also there are foreign social services such as "Instagram", "Facebook" and "Twitter". But the domestic will have to install separately.

What should I add to the OS?

For reading books in different formatsit is recommended to put the "Kingsoft office" on this device. This will also allow you to work with text tables. To view the tables, you must install the "MX Player". Still need to complement the smartphone with antivirus and optimization utility. For these purposes, the "SM security" and "Wedge Master" perfectly suits. All this will significantly improve the performance of the Lenovo S820T. The review of further software does not have a sense to produce, because everything depends on the user's tasks. For example, to perform complex mathematical calculations, you can put a calculator with an expanded set of functions. We also need to install social services for local networks "VKontakte", "My World" and "Classmates". This will allow you to communicate with friends and relatives using your smartphone. In general, all the necessary applications and games can be found and downloaded from the Play-Market.

Data acquisition capabilities

Finally consider the communicationfeatures of this smartphone. For wireless connection to the Global Web, you can use wi-fi (maximum speed up to 100 Mbps) and mobile networks of the third or second generation (in the first case we get a maximum of 3 Mbps, in the second - hundreds of kilobytes). If you want to download large content (for example, a movie), then it's better to stop choosing wi-fi. But to browse sites and communicate in social networks, you can even in the ZhSM-networks. The module ZhSM is installed for navigation. With the "GLONASS" system, he, alas, does not work. On this side, this Lenovo model looks perfect. The S820T phone, an overview of wireless connections on this indicates, is not equipped with an infrared port. But this technology is morally and physically obsolete. So there is nothing to worry about. Among the wired data transfer, the following types of connectors can be distinguished: MicroUSB (for connecting to a PC and charging the battery) and a 3.5 mm audio jack for connecting external speakers or headphones. It should be noted right away that the stereo headset, which comes with a smart phone, is of very poor quality. Therefore, fans of high-quality sound should buy other headphones.

Reviews about the smartphone

Detailed review of Lenovo phones says that this is a branded gadget leadingthe Chinese manufacturer. Problems with the processor, camera, graphics adapter and memory - this is not a complete list of nuances that indicate that this is a fake. Perhaps it is made in the same factory with other devices of this brand, but here the quality leaves much to be desired. This confirms many reviews about this model on various information resources in the Global Web. In general, you need to weigh everything well, before buying this smartphone Lenovo. The phone S820T on paper has excellent specifications and specifications, but in fact it is not.

Summary

Let's sum up. The oddities with the processor, memory and graphics adapter cause a lot of criticism on the Lenovo S820T. Reviews this only confirm. In any case, two cores for today - this is not enough. A similar situation with RAM (only 512 MB in the basic configuration), and with a graphics adapter ("Mali-400" is clearly obsolete). At the same time, Lenovo S820T has practically no positive moments. The price of $ 140 is clearly overstated. If it was based on a high-grade 8-core chip, it was an excellent acquisition. And since the purchase of such a device is not entirely justified today - the cost is overstated, and the filling is not very good.
