Lenovo K900 – 2013 flagship with an Intel processor
Previously, we associated Lenovo primarily with laptops; they were of high quality and did not cause any complaints. Only a few have heard or seen Lenovo phones. Most considered this company’s development in the field of smartphones to be just an appendage to laptops, because many of us were already familiar with the term “Chinese smartphone on Android” and this discouraged the desire to purchase something from their model range.
And mobile phone retail chains were not in a hurry to bring phones from this company to our market. But the most demanding ones wanted to get quality at an affordable price, ordering goods directly from China. You can find out how to do this by studying our material called:
But everything changed dramatically after the company released its flagship, workhorse of 2013 - the Lenovo K900 smartphone with an Intel processor. For many, this was a shock and new. People began to become interested in the company, and dealers got involved and began offering the IdeaPhohe model range in their retail chains. Actually, thanks to this model, most ordinary users learned about the existence of mobile phones from Lenovo. You can view the full list of devices and study their classification by reading the article:
Let's take a closer look at what the Lenovo Ideaphone K900 smartphone is and find out why it might be of interest to us.
Equipment
The device comes in a stylish small box, which is typical for Lenovo, but in this case the box itself looks more stylish than with budget models - this already indicates that there will be something interesting inside.
In addition to the phone in the box, we can see documentation, a paperclip for removing the SIM card, a charger, a microUSB cable, an adapter for a Euro socket and an audio headset.
Characteristics
A special feature of this smartphone is the Intel Atom Z2580 processor, which has 2 cores operating at a frequency of 2 GHz, which, unlike other mobile processors, has a high degree of heating, which should not be surprising when using it. The phone has 2 GB of RAM, and the built-in memory, depending on the device version, is 16 or 32 GB.
The 2500 mAh battery in the device can last two days in energy saving mode, and with active use you will need to charge the smartphone every day, but this is a price to pay for the thickness of the device.

Screen
The Lenovo K900 screen is made on the basis of an IPS matrix with Full HD resolution and high quality image display. The display has wide viewing angles, which indicates its premium quality. Color rendering and contrast do not cause any complaints. At the time of the device's release, the smartphone has one of the best displays among its competitors.
The sound on the phone is loud and of high quality, both from the main and earpiece speakers. According to Antutu Benchmark 3.2.2 tests, the device scored 25827 points, which is simply an excellent indicator.
Camera
There are two cameras in the phone. Front 2 MP and main 13 MP with flash and auto focus. The camera quality is quite high. It is possible to record video in FullHD resolution, but the quality and stabilization could be better.
Appearance
The appearance of the device is quite controversial. Many people consider it a “square shovel”, but many people really like it.
The body has sharp corners and is made of aluminum with polycarbonate inserts painted to look like metal. At the same time, it looks impressive and stylish - the premium quality of the device is immediately felt. On the front side there is a Lenovo logo, a speaker, a 2 MP front camera, proximity and light sensors, a 5.5-inch screen with Gorilla Glass 2 protective coating, and below it are three touch navigation buttons.
On the right side there is a power button, as well as a slot for a micro-sim card. The top edge is made without additional elements. On the left side there is a volume rocker. On the bottom of the case there is a microUSB input, a microphone and a 3.5 input for headphones.
On the back side there is a 13 MP camera with flash, an additional microphone, Lenovo inscription and a speaker grille. The phone fits very well and pleasantly in the hand despite its impressive size.

The development team of this product tried their best and released a truly high-quality product that changed the perception of Lenovo as a manufacturer of mobile devices. The phone is recommended for purchase both for fans of heavy games and for lovers of style - this smartphone is really worth paying attention to.
General characteristics
Type
Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to choose a telephone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.

Almost all modern smartphones have Wi-Fi and USB interfaces. Bluetooth and IRDA are a little less common. Wi-Fi is used to connect to the Internet. USB is used to connect your phone to a computer. Bluetooth is also found in many phones. It is used to connect wireless headphones, to connect your phone to wireless speakers, and also to transfer files. A smartphone equipped with an IRDA interface can be used as a universal remote control. Glossary of terms for the category Mobile phones
Wi-Fi, Bluetooth 3.0, USB Satellite navigation
Built-in GPS and GLONASS modules allow you to determine the phone's coordinates using signals from satellites. In the absence of GPS, a modern smartphone can determine its own location using signals from cellular operator base stations. However, finding coordinates using satellite signals is usually much more accurate. Glossary of terms for the category Mobile phones
GPS A-GPS system yesMemory and processor
CPU
Modern phones and smartphones usually use special processors - SoC (System on Chip, system on a chip), which, in addition to the processor itself, houses the graphics core, memory controller, input/output device controller, etc. Therefore, the processor largely determines the set of functions and device performance.
The stylish and productive flagship solution of 2013, which remains relevant today, is the Lenovo K900. Reviews of this smart phone, its characteristics and specifications will be further discussed in detail, its strengths and weaknesses will be given. Recommendations regarding the purchase of this gadget will also be given.
Design solutions
The body of this device, except for the front panel, is made of thin sheet metal. Its thickness is 6.9 mm. The front panel of the gadget is protected by impact-resistant glass “Gorilla Eye” of the 2nd generation. It has a screen with a diagonal of 5.5 inches. Above the display there are eyes for a number of sensors and, of course, below it there are controls of three standard backlit buttons. The smart phone lock button is located on its right side, and on the left there are typical keys for adjusting the volume of a smartphone. All wired ports (microUSB and audio port) are located on the bottom edge of the device. On the back cover there is a loud speaker and the main camera of the device.
CPU
A very powerful processor is used in the Lenovo K900. Reviews indicate that even 2 years after the start of sales, it easily copes with all tasks, including even the most demanding 3D 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 some criticism is the outdated technological process. The chip is manufactured according to the standards of the 32nm technological process. Due to the increased size of the semiconductor crystal and the transistors themselves, the processor heats up greatly during the highest computing load. But by choosing the right power consumption mode, this issue can be resolved.
Cameras, display and graphics
As expected, the Lenovo K900 cell phone is equipped with two high-quality cameras. 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. It can record video in 1920x1080 quality with an image update of 30 frames per second. The front camera has a more modest sensor - 2 megapixels. Its main tasks are selfies and video calls. She handles them flawlessly. The screen diagonal of this device is 5.5 inches. Its resolution corresponds to the video recording format of the main camera and is equal to 1920x1080. The display matrix is made using the most popular IPS technology today. Viewing angles, image quality, and color saturation do not cause any complaints. The graphics adapter is PowerVR SGX544MP2. Its computing resources are quite sufficient to solve almost all problems that arise today.
Memory
The Lenovo K900 is equipped with an impressive amount of built-in memory. Reviews highlight this feature. The capacity of the integrated drive is 16 GB or 32 GB (there are two modifications of this device, the latter is just a little more expensive). It has 2 GB of RAM. There is no slot for installing a memory card, but OTG technology is implemented, and if you have the appropriate cable, you can connect a regular flash drive to the smartphone. Another way to solve the problem of lack of memory is to use cloud storage services. But, as practice shows, 16 GB should be enough for comfortable work on this device.
Battery
Modest battery capacity of the Lenovo K900. Reviews from users of this gadget indicate this feature. The battery capacity is only 2500 mAh. Add to this a display with an impressive 5.5-inch diagonal even by today’s standards and a productive but energy-efficient processor, and we 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 will not be complete. Reviews indicate the presence of such methods of transmitting information:
- Wi-Fi is the main way to obtain information from the Internet.
- Transmitter for 2nd and 3rd generation mobile networks. In the latter, the maximum data transfer speed can reach 7.2 Mbit/s.
- Another important wireless interface is Bluetooth. With its power, the sound signal can be output to an external device or exchange small files with another device.
- For navigation, the gadget uses GPS and A-GPS technologies.
- The main wired port is microUSB. With its help, the battery is charged and information is exchanged with the PC.
- The smartphone also has a 3.5 mm jack - this is an audio port for connecting a wired speaker system.
Software
This gadget uses the most common and popular software platform, Android, as the OS. Its version is 4.2. A proprietary software shell from Lenovo is installed on top of the operating system. Otherwise, the set of software is familiar: these are utilities from Google, built-in OS applications, and social network clients.
What about the owners?
The Lenovo K900 smartphone turned out to be a very balanced solution. Reviews from the owners of the gadget highlight a number of advantages: an impressive amount of built-in and RAM memory, a powerful processor, a high-quality screen, and a reliable and protected case. This smartphone has certain problems only with autonomy and processor heating. But, as was previously said, the first issue is easily resolved with the help of an additional external battery. In the second case, it is enough just to correctly set the CPU operating mode - and the semiconductor crystal will not overheat.
Results
Even now, 2 years after the start of sales, the Lenovo K900 can easily solve almost all problems. Reviews from satisfied gadget owners prove this. Its cost during this time dropped to 200-250 dollars. At this price it will be difficult to find a more productive and high-quality solution with such characteristics.
