Stylish and productive flagship solution of 2013, which remains relevant today, is the Lenovo K900. Reviews about this smart phone, its characteristics and specifications will be further examined in detail, its strengths and weaknesses are given. Also, recommendations will be given regarding the purchase of this gadget.
Design solutions
The case of this device, in addition to the front panel, is made of sheet metal. Its thickness is 6.9 mm. The front panel of the gadget is protected by shockproof glass "Gorilla Eye" of the 2nd generation. On it is a screen whose diagonal is 5.5 inches. Above the display are the eyes of a number of sensors and, of course, the front camera. Below it, there is a touch control panel of three standard buttons with backlight. The lock button of the smart phone is displayed on its right side, and on the left are typical keys for adjusting the volume of the smartphone. All wired ports (microUSB and audio port) are displayed on the bottom of the device. On the back cover is a loud speaker and the main camera of the device.
CPU
A very productive processor is used in the Lenovo K900. The reviews indicate that even 2 years after the start of sales, he easily copes with all tasks, including even the most demanding three-dimensional toys of the latest generation. This device uses the ATOM Z2850 chip from Intel. This semiconductor chip includes 2 computing cores, each of which can operate in 2 computing threads. As a result, we get a quad-core solution at the software level. The clock frequency of each computing module is 2 GHz. The result is a phenomenally high level of performance for this processor solution. The only thing that causes certain complaints is the outdated technological process. The chip is manufactured according to the standards of the 32-nm process. Due to the increased size of the semiconductor chip and the transistors themselves, the processor heats up very much under the highest computational load. But due to the correct choice of energy consumption mode, this issue is being addressed.
Cameras, display and graphics
As expected, the Lenovo K900 cell phone is equipped with two high-quality cameras at once. Reviews indicate the high quality of photos and videos obtained with their help. The main camera is based on a 13 megapixel sensor. There are autofocus and backlight systems. She can record video in the quality of 1920x1080 with an image update of 30 frames per second. At the front camera, the sensor is more modest - 2 megapixels. Its main tasks are “selfies” and video calls. She copes with them flawlessly. The screen size in this device is 5.5 inches. Its resolution corresponds to the video format of the main camera and is equal to 1920x1080. The display matrix is manufactured using the most popular IPS technology to date. Viewing angles, image quality, its color saturation are not satisfactory. The PowerVR SGX544MP2 acts as a graphics adapter. Its computing resources are quite enough to solve almost all the problems that arise today.
Memory
An impressive amount of internal memory is equipped with Lenovo K900. Reviews highlight this feature. The capacity of the integrated drive is 16 GB or 32 GB (there are two modifications to this device, the latter is just a little more expensive). RAM in it - 2 GB. There is no slot for installing a memory card, but OTG technology is implemented, and you can connect a regular flash drive to your smartphone with the appropriate cable. Another way to solve the memory shortage problem is to use cloud storage services. But, as practice shows, 16 GB should be enough for comfortable work on this device.
Battery
The modest capacity of the Lenovo K900 battery. User reviews of this gadget indicate this feature. The battery capacity is only 2500 mAh. Add to this a display with an impressive 5.5 inches diagonal even by today's standards and a productive, but non-energy-efficient processor, and get 1-2 days of battery life. This problem can be solved by purchasing an additional external battery. In this case, the indicated value may increase to 4-5 days (depending on the capacity of the external battery).
Information exchange
Now about the interface set of this device. Without this list, the Lenovo K900 review would not be complete. Reviews and technical documentation indicate the presence of such methods of transmitting information:
- Wi-Fi is the main way to get information from the Internet.
- 2nd and 3rd generation mobile networks transmitter. In the latter, the maximum data exchange rate can reach 7.2 Mbps.
- Another important wireless interface is Bluetooth. With its help, the sound signal can be output to external wireless speakers or share small files with another device.
- To implement navigation in the gadget, GPS and A-GPS technologies are implemented.
- The main wired port is microUSB. With its help, the battery is charged and information is exchanged with a PC.
- Also, the smartphone has a 3.5 mm jack - this is an audio port for connecting a wired speaker system.
Software
As the OS in this gadget, the most common and popular Android software platform is used. Its version is 4.2. A proprietary software shell from Lenovo was installed on top of the operating system. The rest of the software is familiar: these are the utilities from Google, and embedded OS applications, and social network clients.
But what about the owners?
A very balanced solution was the Lenovo K900 smartphone. Reviews of the owners of the gadget give it a number of advantages: an impressive amount of built-in and RAM, a powerful processor, a high-quality screen, a reliable and protected case. This smartphone has certain problems only with the autonomy and heating of the processor. But, as was previously said, the first issue is easily solved with the help of an additional external battery. In the second case, it is enough just to set the CPU operation mode correctly - and there will be no overheating of the semiconductor crystal.
Summary
Even now, 2 years after the start of sales, almost all tasks are easily solved by Lenovo K900. Reviews of satisfied gadget owners prove this. Its value during this time dropped to 200-250 dollars. At a similar price it will be difficult to find a more productive and high-quality solution with such characteristics.
