Do you think the selling point of smart phones now should be photography or processor?

First of all, what you need to know is what kind of processor you want this phone to carry.

The processor is the most important part of the mobile phone. It is responsible for handling all kinds of information such as operation, including clicking on the screen, which is within its operating range. The quality of the processor directly affects the running speed and fluency of the mobile phone. Judging from the current use of processors in the smart phone market, many brand models mostly use American Qualcomm processors. Qualcomm is not the only processor, so it is necessary to know which processor you are using before you buy a mobile phone. The following figure is the ladder diagram of the processor (which is equivalent to the horizontal row)

You can know which grade of smart phone you bought by the above picture. You can also avoid being fooled by bad businesses. Of course, the factors that affect the running speed of a mobile phone can not only lie in the processor, but also include the running memory and physical memory of the mobile phone.

Second, run memory RAM and physical memory ROM.

I won't explain what RAM and ROM are here, so as not to waste your precious time. If you have any questions, you can do it yourself. At present, the smart phones on the market extend from 5 12M RAM to 8G RAM, and the physical rom is as high as 5 12G or even1t.. Running memory and physical memory are matched with each other, and running memory is divided into DDR*. On the premise of sufficient capacity, the higher the ROM frequency, the better. 4GB DDR4 is definitely better than 6G DDR3. At present, high-end configuration has also become an indicator of high-end machines. 1GB is too small, 2GB is not enough (the current entry configuration), 3GB is barely, 4GB is moderate, 6GB is enough, and 8GB is redundant.

The third point is the resolution of the mobile phone screen.

The screen resolution of mobile phone directly affects the display effect of mobile phone, and also has a great influence on eye vision. Some smart phones have beautiful appearance and good configuration, but the resolution is extremely low, which will hurt your eyes if you use them for a long time. Of course, the higher the screen resolution, the clearer it is. For example, an Android phone with a 5.5-inch screen resolution of 1920× 1080 has a corresponding wallpaper resolution of 1920× 1080. The larger the screen size, the clearer the screen. You can also calculate the screen resolution density. The higher the resolution density, the larger the pixel value of the mobile phone screen, the better. The future trend is more like the development of 4K screens, and some low-end screens will eventually be eliminated.

Fourth, the mobile phone camera.

The camera affects the effect of taking pictures. Friends who like to take pictures have very high requirements for cameras. The minimum requirements cannot be lower than the front 8 million and the rear1200,000, which is the most basic. The dual camera of Huawei P20 series has also become the object of imitation now, and Lycra dual camera is a trend of smart phones in the future. Pixels will directly affect the imaging effect, and the resolution of the photos taken has a great influence, which is also related to the camera lens and sensor. For how to choose a good product, we must first understand the importance of aperture. Generally speaking, the larger the aperture, the better. The aperture of F2.0 and the aperture of F 1.7 should not be counted as F2.0, but the smaller the value, the better.

Fifth, the endurance of mobile phones and batteries.

A good product won't let you go out in the morning. Turn off your cell phone before you go home from work. Most smart phone batteries are not durable. Even so, don't buy a mobile phone casually. If you don't know the battery capacity of your mobile phone, you are looking for trouble for yourself. Otherwise, no matter how well configured the mobile phone is, no electricity is equivalent to no mobile phone. Battery life is directly related to the screen size. The larger the screen, the higher the relative power consumption. If you want to start with a large-screen mobile phone, you must first choose a larger battery capacity. The minimum value is 3750 mA. More than 4000 mA is more stable.

Finally, there is the price that has to be said.

When buying any product, we will care about its price. Relatively speaking, the higher the price, the higher the quality and the higher the grade. However, we can't just pursue products. Products with high quality and good price should be selected according to their own conditions and exceed the budget standard, so forced purchase will bring potential burden to themselves. Buying with the wind will increase your regret. Of course, the price is not suitable for everyone, and it is most important to do what you can. Don't choose the right mobile phone, don't choose the expensive one, only choose the one that suits you.
