How to distinguish a good mobile phone from a bad one? A knowledgeable person teaches you not to waste money. Look at these three points.

How to identify the mobile phone you want to buy, is it good or bad? In fact, you only need to look at these three points to know.

First: Can you meet your own needs?

A good mobile phone doesn't mean more powerful performance and a top screen. The most important thing is to see if the mobile phone can meet your own needs. If you want to protect your eyes, the top screen is not a good choice. The top screen is basically an organic light-emitting diode screen. If you want to protect your eyes, you should choose an LCD screen, because the LCD screen has a unique eye protection effect and supports DC dimming. By adjusting the voltage or current to change the brightness of the screen, the effect of not flashing the screen can be achieved. However, the OLED screen uses PWM dimming, which will always flash when it works, which is what we often call stroboscopic. Some people are particularly sensitive to stroboscopic, so their eyes will soon get tired. For another example, if you pursue images, it depends on whether there are several lenses in the lens. For example, Xiaomi's/kloc-0.02 million depth-of-field lens can achieve the effect, and/kloc-0.30 million ultra-wide-angle lens can do it. OPPO Find X3Pro, 300W macro, 60 times zoom effect is not great.

Second: while meeting its own needs, the performance should conform to the mainstream.

There are many aspects of performance, first of all, the processor, it is best to choose powerful processors, such as Snapdragon 870, Snapdragon 778G, Tianji 1200, Apple A series chips and so on, to see whether the mobile phone screen supports high brush. At present, most mobile phones support 120Hz high brush, but the screen of OPPO Reno 7 only supports 90Hz refresh rate. In terms of battery life, the power consumption of the 5nm flagship chip has greatly increased, and even some 5000mAh large battery mobile phones have not brought excellent battery life performance, so if it is lower than 4500mAh, the battery life performance will not be too good. When you buy it, you must look at the evaluation of digital bloggers. Many bloggers will conduct a five-hour endurance test on heavily used mobile phones. Friends can refer to this value to compare the battery life of mobile phones. If you buy a mobile phone with poor battery life, you might as well recycle it everywhere. For example, the recycling price of iQOO Z5X is 1080, and the recycling price of Glory 30S is 12 10, and it can be recycled at home, which is convenient and can reduce the pressure of changing machines.

Thirdly, the quality control of mobile phones is also very important.

If the above two points make you think that the mobile phone you bought is a good one, take a look at the last point. In terms of quality control of mobile phones, friends should carefully check whether the package is in good condition, look at the factory date on the box, check whether the mobile phone has been activated, and check whether the camera is dusty, scratched and bumped on the body, whether there is an excessive gap between the frame and the back cover, whether the volume power button is loose and whether the camera is crooked after taking out the mobile phone. For mobile phones with quality control problems, hurry back! I hope everyone has a tolerant attitude towards quality control.
