1 is the CPU, the current mobile phone CPU brands in the market include Qualcomm, Huawei, Texas Instruments, Intel, new forces and so on.

Then the frequency of the CPU. The higher the CPU frequency, the faster the processing program. Take Samsung GALAXY Note 3 as an example: The CPU frequency is 2355MHz, which is close to 2G. For the average user, this is relatively high.

2 is the memory ROM, how many programs a smart phone can be installed, to a large extent determined by its ROM, we can understand her capacity as a mobile phone, similar to the computer's local disk. The larger the ROM, the more data that can be accommodated.

3 is to run the memory that is also shipped RAM, the size of RAM is also crucial. Take an Android phone as an example. Because of its own characteristics, the Android system will prioritize the software installed on the mobile phone. Sometimes the Android system will automatically invoke the mobile phone software to run in the background. The advantage is that the next time you open this software, the speed will be very high. fast. However, this also has a drawback, it is the phone's RAM. So when your phone's RAM is as small as 500MB, 300MB or even lower, you will find that when you use your phone, some programs will be closed automatically. It is based on this feature that if we open many programs at the same time, and if RAM is not enough, the system will give priority to those programs with lower priority.

However, the screen is too large to be portable, so the choice of screen size depends on personal habits. In addition, when the screen size is the same, the resolution is not necessarily the same. When the size of the screen is the same, the higher the screen, the clearer the displayed image. Therefore, it is recommended that friends choose what to look for on the screen when choosing a mobile phone. If you compare them, you can see the difference.

5 is the camera pixel, and the pixels of the smart phone are the more important parameters for measuring the performance of a smartphone. Also taking the Samsung GALAXY Note 3 above as an example, the camera has 13 million pixels. The effect of such high pixel photography can be comparable to a digital camera. If the pixel requirement is not too high, users can choose 8 million pixels, or 5 million pixels. In general, the rear camera pixel should not be less than 3 million pixels. If it is lower than this, the effect will not be satisfactory. If a mobile phone has a flash, it's even better. Even if you don't need it, we just need to download the right flashlight software.
