Lenovo K900 32GB is a flagship smartphone that has almost everything that a modern premium device can have. He made his debut in 2013, but even now, a year later, his characteristics allow him to solve all problems without exception.
What's included?
Since Lenovo IDEAPHONE K900 32GB is one of the most productive solutions, it has the appropriate bundle. The composition of the boxed version of "K900" includes:
- The smartphone itself.
- 2500 milliamp/hour battery.
- Charger.
- Cord - USB/MicroUSB adapter.
- Protective film.
- Case - silicone bumper.
- User's manual.
- Warranty card.
The only thing missing is an external flash drive. The problem is that the smartphone itself does not provide a slot for installing it. Therefore, you will have to be content with the built-in memory. In extreme cases, you can install an external USB flash drive using the OTJ - cord (it will also have to be purchased separately). Another question thatarises, is the expediency of using a protective film and a bumper cover. The front panel of the device is made of protective glass, and the back cover is made of stainless steel. As in the first case, so in the second it will be difficult to damage the body of the gadget.
The appearance of the gadget and the convenience of working on it
Lenovo K900 32GB BLACK looks like a "shovel". The dimensions of the smartphone are really impressive: 157mm by 78mm. At the same time, its thickness and weight are 6.9 mm and 162 grams, respectively. It is very difficult to control it with just one hand. Dimensions still make themselves felt. The front part, as noted earlier, is made of protective glass "Gorilla Eye" of the 2nd generation. The back cover is made of stainless steel. Only narrow strips on top and bottom of plastic. Above the display is a speaker and a camera for making video calls. Under the screen are the classic touch buttons: "Menu", "Home" and "Back". The usual control buttons are not very conveniently located. You can turn on the device on one side, and the volume swings are located on the opposite edge. But the connectors for wired interfaces are located on the lower edge of the device. There is also a speaking microphone.
What about the processor?
The strength of the Lenovo K900 32GB is the CPU. In this case, we are talking about ATOM Z2580 from Intel. Physically, it has 2 computational cores, but due to the use of the HyperTrading proprietary technology, the number of computational threads increases2 times. Another feature of this CPU is its clock speed of 2 GHz. Let's put it this way: not every solution today can boast of such a characteristic. But not everything is as perfect as it seems at first glance. The core architecture of this CPU is "x86". But the majority of Android devices operate on ARM solutions. If you do not go into details, then we can say that there may be problems with the application software. But this is only a conditional remark, which in most cases does not manifest itself.
Graphics subsystem and display
Sufficiently productive installed graphics adapter in Lenovo K900 32GB. In this case, we are talking about PowerVR SGX544MP2. This is a productive solution that can easily cope with the task of any level of complexity, for example, the demanding toy "Asph alt 8" on this gadget runs without problems. The perfect complement to this graphics adapter is a display with a diagonal of 5 and a half inches with a resolution of "HD", that is, its resolution is 1920 by 1080. Another positive point is that the screen is based on an IPS matrix. This ensures high image quality and viewing angles as close as possible to 180 degrees. As it should be for a device of this class, the display is capable of displaying more than 16 million colors and processing up to 5 touches to its surface. Also, the indisputable advantage of this model is that the screen is protected by glass "Gorilla Eye" -2nd generation.
Cameras and their capabilities
The situation with this model is not entirely clear around the main camera. On the one hand, she has everything in order to get high-quality pictures and videos. This is a matrix of 13 megapixels, and autofocus, and LED backlight. But if the photos are of acceptable quality, then there are certain problems with the video. Most likely, they are associated with the lack of an automatic image stabilization system. This leads to the fact that the frame in the video may turn out blurry. There is also a front camera. Its main task is to make video calls. She copes with this task without any problems. Moreover, it is based on a 2 megapixel matrix. This is quite enough for a high-quality image during video calls.
Memory subsystem
An interesting situation with this model develops with the memory subsystem. If everything is clear and unambiguous with RAM - 2 GB, then options are possible with a built-in drive. Initially, 16 GB was integrated into this model. But a little later, a more advanced modification appeared - Lenovo K900 32GB. A review of its specifications indicates that the difference between them is only in the size of the flash drive. And very significant - 2 times. Accordingly, the cost of the latter is much higher. Therefore, do not forget to check with the seller the amount of installed memory. The situation with memory cards is much worse. There is no slot for installing them in this smartphone. If for some reason 16 GB or 32 GB of internal memory is not enough for you, thenyou can increase its volume only with the help of an “OTZH” cable and a regular USB flash drive.
Autonomy
The weak link in this premium smartphone is the battery. Its capacity is "only" 2500 mA / h, and this value is most likely due to the case thickness of 6.9 mm. Chinese engineers had to choose between the thickness of the smartphone and its autonomy. As a result, the choice was made in favor of the first, and the second parameter faded into the background. Given the screen diagonal of 5.5 inches and a productive processor, 2500 milliamp / hours is clearly not enough. In the best case, one charge is enough for a day of intensive workload. If you use the minimum power consumption mode, then you can increase this figure to 2 days, which is also not so much. The only correct solution in such a situation is to additionally purchase an external MicroUSB - battery and with its help significantly increase the degree of autonomy of this device. Otherwise, he may let you down at the most inopportune moment.
System Software
Smartphone Lenovo K900 32GB operates under the most popular operating system at the moment - "Android". Installed firmware with serial number "4.2". In fact, this version is a little outdated. But, all the same, in the foreseeable future, compatibility problems should not arise. Given the fact that the smartphone debuted more than a year ago, it is no longer necessary to expect updates. So you have to be content with what you have. Android itself is not installedin the nude. The add-on is Lenovo Launcher, which allows you to easily optimize the interface of a smart smartphone for the needs of the user.
Application software
Lenovo smartphones always come with a rich set of application software. "K900" in this regard is no exception. In addition to the previously mentioned Lenovo Launcher, a standard set of utilities from Google is also installed on this device. Here is the mail client, and the social service Google +, and Evernote for instant messaging. There are also international social services such as Instagram, Facebook and, of course, Twitter.
Communications
Lenovo K900 32GB has a very extensive set of communications. A review of the technical specifications indicates the presence of the following wired and wireless interfaces:
- One SIM card that can work in 2nd and 3rd generation networks with the help of built-in transmitters. In the first case, the information transfer rate will be 560 kb/s, and in the second - 7.2 Mb/s.
- "Wi-Fi" capable of operating at speeds up to 300 Mbps.
- Bluetooth 2nd generation.
- Built-in "ZHPS" - the transmitter allows you to easily turn this device into a regular navigator. So with this smartphone it will be difficult to get lost on the ground.
- Universal USB 2.0/MicroUSB performs 2 tasks at once. One of them is connecting to a PC to exchange information with it. The second is battery charging.
- The last connector is a 3.5mm jack for connecting an externalspeaker system.
CV
Lenovo K900 32GB turned out to be quite balanced. Powerful processor, powerful graphics adapter, impressive screen size with excellent resolution, enough memory. But still there are negative sides to this gadget. First of all, a small amount of battery for such a large and productive smartphone. As noted earlier, this problem can be solved. You just need to additionally purchase an external MicroUSB - battery. In the second case, the situation is similar. An external memory card cannot be installed in the "K900". Required slot not available. But with the help of "OTZH" - a cable and a regular flash drive, this problem can be solved. In general, the Lenovo K900 32GB turned out to be almost perfect. The price for it is $345, which is not so much for a device of this class.
