It is easy for laymen to be confused when buying mobile phones. These parameters are not important. Don't be deceived by merchants.

1. Mobile phone macro and portrait lenses, especially 2 million make-up lenses

Nowadays, mobile phone imaging not only competes in pixels and aperture size, but also in the number of lenses. If others have four cameras and you have three or two cameras, you will be dissed by competitors. Therefore, some manufacturers will use make-up lenses in order to make up the number of cameras. The mainstream make-up lenses include 2-megapixel black and white, 2-megapixel portrait, 2-megapixel macro, etc. In short, no matter what the 2-megapixel lens is used for, the ultimate purpose is to make up the number.

The quality of mobile phone images depends on the aperture size, pixel height, sensor model and the most critical post-optimization. The same sensor used in different mobile phones will result in different picture colors, white balance and anti-shake.

2. In theory, the bigger the battery, the better, but the battery life depends on the software and hardware tuning

In theory, the battery capacity can be used to directly judge whether the battery life is good or bad. A mobile phone with a 5000mAh battery will theoretically have better battery life than a 4000mAh one, but this is not necessarily the case for 5000mAh and 4500mAh, especially this year's Snapdragon 888 flagship mobile phones. Some manufacturers have launched 5000mAh mobile phones, but their battery life is very poor due to poor software and hardware optimization.

In addition, there will be offline salesmen who will "fool" you, saying that a certain mobile phone is equipped with a 5000mAh battery and has excellent battery life. In fact, if this mobile phone is positioned in the mid-to-low-end market, the chip power consumption is low, so even with a 4500mAh battery, the battery life can still be excellent.

3. The processor core is not the focus, the focus is on the processor model and positioning

Offline salespeople will tell you that a certain mobile phone is equipped with the latest "octa-core" processor, but there are many octa-core processors, and their positioning is different. For example, Snapdragon 480 is positioned in the low-end market and is an octa-core processor; Snapdragon 888 is positioned in the flagship market and is also an octa-core processor.

Therefore, when buying a mobile phone, be sure to ask the salesperson about the specific model of the processor the phone is equipped with, and then search the online rankings and prices of mobile phones with the same processor to have a clear idea and avoid buying a "high-priced, low-spec" phone.

4. The running score of the mobile phone is not important, what is important is the experience

Running scores can reflect the performance of a mobile phone, but they do not represent the quality of the experience. Some manufacturers claim that running scores are not important, but they still announce running scores at every press conference. Some manufacturers even announce laboratory data, and users will never be able to achieve the manufacturer's scores after getting their hands on the phone.

The most crucial thing is that some manufacturers will "cheat" in running scores. Domestic manufacturers have been named earlier, so everyone is equipped with the same processor, and the performance gap will not be too big. Whether the experience is good or bad depends mainly on software and hardware optimization.

Final words

In addition to the above four parameters that are not worth worrying about too much, there are many more details that the author has not listed one by one, such as the fast charging power of the mobile phone, the screen resolution of the mobile phone, etc. It may be difficult for an outsider to become an expert and understand every parameter of the mobile phone, but mastering the above four points can at least help you avoid some pitfalls.
