There are three points that can easily lead to misleading when buying a mobile phone. If you understand them, you will be considered an expert and can save a lot of money.

Today, I will talk to you about 3 points that are easy to be misled when buying a mobile phone. Let's see if you have stepped on the pit?

First, the higher the screen refresh rate, the better? Since when, Android flagship phones have become standard with the essential parameter of high refresh screen rate. Even thousand-yuan phones have a refresh rate of 120Hz.

How to understand the screen refresh rate? For example, if you play with your phone for a while at night without lights, your eyes will be a little tired and you close your eyes. At this time, you will definitely see the residual image of the phone, which is the phenomenon of visual persistence. However, if an object flies quickly in front of your eyes, you will not feel this phenomenon.

A high refresh rate screen produces less motion blur when sliding quickly, making people feel extremely smooth. However, the visual recognition range of the human eye is limited! No matter how high the refresh rate is, it doesn't work for you. What's the point? It's better to pay more attention to the user experience when buying a mobile phone, just practicality.

Second, the processor is important and can represent everything? If you think so, you are totally wrong. Chip performance is important, but other accessories are equally important, such as memory and flash memory. In addition, the additional functions of the mobile phone, such as whether it supports NFC, etc., are also worth paying attention to.

We need to pay more attention to the details of the mobile phone, such as whether the waterproof level can reach IPX68? Can the total charging time be compressed to less than 40 minutes? Does its battery capacity exceed the 4200 mAh mark?

Third, is the pixel value of a mobile phone proportional to the level of photography? Many people think that the higher the pixel, the better the photography performance, but this view is wrong. If you want a good shooting effect, you might as well understand the CMOS sensor model of the mobile phone. After all, its size determines the amount of light entering the image module and also determines the photography effect of the main camera.

Finally, when buying a mobile phone, you should learn as many aspects as possible, and you should not generalize based on just a few parameters. If a store only boasts about the camera pixels and refresh rate of a mobile phone and sells it at a high price, then you should be careful.
