We just brought it up ahead Lenovo K860i Unpacking It can be seen from the unpacking that the appearance of the new K860i is basically unchanged from the previous K860, and it also adopts a stable and atmospheric design style. Lenovo K860i has made some improvements in its internal hardware, increasing the CPU frequency to 1.6GHz, and upgrading 1GB memory to 2GB, supplemented by 16GB body storage space. In terms of feature functions, Lenovo K860i has added the electronic compass function to enhance the navigation service. How much has it improved? Let's take a look at the following evaluation.

Appearance and screen

The design style of Lenovo K860i is more stable, which makes people feel more suitable for business people. The 195g fuselage weight is more weighty than the general model, and it is heavy in the hand. The thickness of Lenovo K860i fuselage is 9.6 mm, which is not very thin, but it also reaches the current mainstream level. The front design of K860i is simple, and the control keys are integrated on the screen, which is the same as the Nexus 4. The back is a plastic back shell, and the surface is a grainy grid design. The K860i camera is slightly higher than the average height of the back. It is equipped with dual flash lights, and the overall texture is good.

In terms of screen, the Lenovo K860i uses a 1280x720 pixel high-definition screen, which is 5 inches in size. The calculated PPI is 294, which is higher than the first and second generation of Samsung GALAXY Note. The screen performance is exquisite. Without careful observation, you can't see the graininess. In terms of screen material, the official introduction is AH-IPS (3rd generation). Intuitively, it can be felt that the color temperature of this screen is slightly warm, similar to the effect of Xiaomi 2, different from the cool and gorgeous effect of Samsung Amoled screen, and obvious contrast with the cold and white tone of vivo X1.

Four leaf clover interface

Lenovo K860i continues the classic four leaf clover interface. The customized interface shows the differences of this model. However, compared with MIUI and Flyme, the theme is relatively small. Thanks to the support of powerful hardware, the interface effect has been quite smooth, and the use experience is also good.

New function: electronic compass

Compared with the previous K860, Lenovo K860i has added a new electronic compass function. What is this function?

The electronic compass, also known as the digital compass, is a method of using the geomagnetic field to determine the North Pole. Now there are generally electronic compasses made of magnetoresistive sensors and fluxgates. Although GPS has a wide range of applications in navigation, positioning, speed measurement and orientation, its signal is often blocked by terrain and ground objects, resulting in a greatly reduced accuracy, or even can not be used. Especially in urban areas with high-rise buildings and densely vegetated forest areas, the effectiveness of GPS signals is only 60%. In addition, GPS cannot give the heading information when it is still. In order to make up for this deficiency, we can adopt the method of integrated navigation orientation. Electronic compass products are designed to meet such needs of users. It can effectively compensate the GPS signal to ensure that the navigation and orientation information is 100% effective, and it can work normally even after the GPS signal is locked, so as to "lose the star without losing the direction".

Hardware score

The improvement of Lenovo K860i over the previous generation K860 is that the frequency of the quad core Samsung Exynos 4412 is increased from 1.4GHz to 1.6GHz, and the memory is also relatively doubled. In terms of intuitive experience, if you don't open too many tasks, you can hardly feel much difference. After opening multiple background tasks, the advantage of large memory is obvious. The following is for reference by running scores.

① , Antu rabbit evaluation

Anthare evaluation is a software for performance evaluation and scoring of Android mobile phones and tablets. It can run a complete test item with one key, and give an overall score to the hardware performance of mobile phones through eight performance tests, including "memory performance", "CPU integer performance", "CPU floating point performance", "2D and 3D drawing performance", "database IO", and "SD card reading and writing speed", Its interface is simple and clear, which is highly praised by domestic DIY players.

② Quadrant Advanced test

Quadrant Advanced is the oldest and best known performance testing software in the Android platform. Based on the Java language, it tests and evaluates the comprehensive performance of the tablet through CPU, memory, 2D graphics, 3D graphics, input and output, and provides a comparison of several mainstream mobile devices, Let's see the comprehensive performance score of the tablet more intuitively. Because the test items are detailed and numerous, this software has been praised by many famous foreign scientific and technological media, and is a very excellent comprehensive performance evaluation software.

③ Vellamo test

Vellamo is a benchmark application (similar to Neocore) developed by Qualcomm. It allows you to test the performance and stability of mobile browsers, including Java script performance, rendering, networking and user interface. The results of this tool also include multiple sub items, but we only take the total score. The higher the score, the better the mobile phone optimizes the browser and the better the web browsing experience.

④ Linpack for Android test

Linpack for Android is a performance test software used to test the floating point performance of Android tablet system CPU. This software evaluates the floating point performance of Android tablet by using the Gauss elimination method to solve the unary N-degree dense linear algebraic equations. The new version of Linpack for Android performance test software can fully call the two processors in the dual core tablet under the requirements of high load computing to achieve the accuracy of the test.

Standby capacity

Lenovo K860i mobile phone is designed with detachable battery, equipped with 2250mAh capacity battery, reaching the mainstream level. Under the daily use intensity, it is not a problem to maintain the use time of one day. In addition, it is also equipped with a TF card slot, leaving the space for users to choose, which is very convenient for users with large capacity requirements.

Summary:

As an upgraded version of K860, the overall change of Lenovo K860i mobile phone is not significant. For daily applications, there is basically no difference. However, the price of these two products is several hundred yuan different. It is recommended that consumers choose to buy according to their actual needs, and there is no need to blindly pursue new products.
