Lenovo S820: reviews, specifications and features of this device - that's what will be discussed in this short review. This device has been on sale for over a year, but even now its performance allows you to easily solve most tasks. At the same time, its price has significantly decreased during this time, but the quality has not changed. The reliability of the gadget does not cause any complaints - the device works stably.
CPU
Smartphone Lenovo S820 is equipped with a productive processor model 6589 with index "W" from the Chinese company "MediaTEK". It consists of four cores of the Cortex A7 revision, and each of them operates at a frequency of 1.2 GHz in the highest load mode. If the device is not loaded or is in standby mode, then their frequency is reduced to 250 MHz. With a minimum load, a situation is possible when in general only one of them is in operation. This decision of Chinese engineers can significantly save battery life. But all these are “dry” figures, which are incomprehensible to poorly informed buyers. In fact, the resources of this CPU are sufficient for most tasks: watching movies, listening to music and radio, surfing the web, typing and editing office documents. Even with toys there should be no problems with rare exceptions. Only the most demanding applications of the latest generation of such a plan will not be able to work on a device that has an MTK 6589 processor with the “W” index installed.
Graphics adapter and screen
A large 4.7-inch screen and a high-performance graphics adapter are the strengths of this smartphone model. The screen resolution is 1280x720 pixels, that is, the picture on the screen is displayed in hd quality. The pixel density at the same time is acceptable today 312 PPI. The type of IPS matrix used provides maximum viewing angles for the Lenovo S820 display. The screen and quad-core processor are harmoniously complemented by the SGX 544 graphics card developed by PowerVR. In sum, all of the above allows you to provide a high-quality image on the display screen, which, moreover, moves smoothly, without jerks.
Appearance and usability
This smartphone has rather impressive overall dimensions: length 139 mm, height 69 mm and thickness 8.9 mm. The weight of the device is only 143 g! Despite the fact that the Lenovo S820 display has a diagonal of 4.7inches, the device is easily placed in the hand and allows you to safely control yourself even with one hand. According to the characteristics, this smartphone belongs to the class of monoblocks with the possibility of touch input. The front panel of the device is made of protective glass, which eliminates the need for a protective film that comes with the device, so there are no problems with protecting the front of the gadget. In the upper part, next to the earpiece, there is a camera for making video calls and a light sensor. Under the screen are three "classic" buttons: "Home", "Back" and "Menu". Around the perimeter and on the back side of the smartphone case is made of plastic. On the left are the volume swings, on top, closer to the right corner, there is a button to turn off the gadget. Next to it is a jack for connecting external speakers. There is a micro USB connector at the bottom middle.
It allows you to both charge the battery and exchange information with the computer. On the back side there is only the main camera with LED backlight. The phone is available in three colors: white, red and grey. The first option is not entirely practical - dirt is visible. But Lenovo S820 RED is perfect for those women who like to wear a lot of red things. It will harmoniously complement their appearance.
The gray modification is universal. It does not get dirty much, and looks solid. Fits everything you can.
Memory and its quantity
Lenovo S820 WHITE like othersmodification of this device, equipped with 1GB of RAM. This volume is quite enough for comfortable work on this device. Integrated flash memory 4 GB. It is distributed as follows: 1.2 GB is the operating system itself, 0.8 GB is used to install applications and utilities, and 2 GB is intended for storing user information. All this is clearly not enough for comfortable work, so you can't do without an additional micro-CD drive. This card is installed in the expansion slot and its maximum capacity can be equal to 64 GB. It is not included in the initial configuration - you will have to buy it separately.
Communications
The set of communications for this model is quite wide. This list contains:
- Wi-Fi for high-speed access to the global web;
- Supports 2nd and 3rd generation networks, both for making calls and for connecting to the Internet. It is necessary to note one important nuance. Only one SIM card, which is installed in slot 1, works with 3rd generation networks. But the second one can function in the gsm standard, that is, the 2nd generation.
- Bluetooth for sharing small files with similar devices.
- Micro USB that allows you to exchange information with a PC.
- GPS module provides navigation.
Among the shortcomings, one can single out that there is no infrared port and support for 4th generation networks. In the first case, there is nothing to worry about. This standard is outdated, both morally and physically. To replace himbluetooth came. But the second remark is significant. Without support for 4th generation networks, it is impossible to get high-speed access to the global web. But so far this standard has not become widespread and it is not possible to use it everywhere.
Battery and its real possibilities
In the boxed version of the Lenovo S820 GRAY comes with a 2000 milliamp battery. According to the manufacturer, its capacity will be enough for 10 hours of communication in third-generation networks and for 22 hours of the second. You can listen to music on one charge for up to 12 hours. In reality, with a non-intensive load, this device will work autonomously for 3-4 days. This is quite a decent indicator for a device with such hardware and a large screen size.
Cameras
Like most similar devices, this device has two cameras. One of them at 2 megapixels is brought to the front of the gadget and is designed for video communication. It is not necessary to expect high-quality pictures and impeccable video recording from her. But the second at 12 megapixels is displayed on the back cover of the smartphone and is great for this kind of task. In addition, for shooting in the dark, it is equipped with LED backlight. An image stabilization system is also implemented. The resolution of the videos obtained with it is 1920 pixels in length and 1080 pixels in width, that is, in full HD quality.
software
Unfortunately, not the latest version of the OS is installed by the manufacturer on LenovoS820. Owner reviews indicate that Android is now installed by default with serial number 4.2. In general, there is nothing wrong with this. Most programs can run on this modern device without any problems. There is no need to wait for system updates yet, although the leading Chinese manufacturer may release an upgrade. The OS itself is installed with additional settings. Among them, we can highlight the presence of Lenovo Launcher, which allows you to easily and easily customize the device interface for the needs of each user. Among the pre-installed software, international social services can be distinguished. But their domestic counterparts will have to be installed separately. Also, the main Google applications (Gmail+ social service, Gmail mail client, Google maps) are installed on this smartphone model.

A year later, the Lenovo S820 smartphone still continues to be a fairly balanced device. Feedback from satisfied owners of this gadget is another confirmation of this. Chinese engineers did an excellent job of creating the hardware. The processor does not overheat. The results of crash tests show the high stability of the gadget. The software component also raises no objections. "Glitches" and freezes on the device were not noticed by users. All in all, a great product that will last you for years.

He has no weaknesses, andit has everything you need for work and entertainment: a flawless processor, a large screen, a powerful graphics adapter, a wide range of communications. The price of the device today is a modest $160. In general, this smartphone will be an excellent purchase that will serve you faithfully for more than one year.
