Since the era of smart phones, a small mobile phone has been given more and more uses and missions. Today’s mobile phones are no longer just a tool for communication, but have become an inseparable part of our lives. . Although mobile phones have many functions, not every function is practical. Today, we will take stock of the flashy functions that some manufacturers have built on mobile phones for marketing gimmicks.
Super fast charging over 80W
Nowadays, mobile phones are charging faster and faster. The fastest charging speed of mobile phones on the market has reached 150W, and even 200W super flash charging is about to be launched. For uninformed consumers, the faster the charging speed, the better. However, this is not the actual situation.
personally thinks that the charging speed is almost enough when it reaches 80W. As the charging power increases, the experience improvement brought by fast charging will become smaller and smaller. The experience improvement brought by 20W to 80W is the most obvious. Taking a 4500 mAh battery as an example, it takes about an hour and a half to fully charge 20W, while it only takes more than 20 minutes to fully charge 80W, which is an improvement of more than an hour. As the charging power goes up, the improvement is not very obvious. Even with 150W super flash charging, it takes more than 10 minutes to fully charge, which is not much faster than 80W.
In addition, high-power fast charging has very strict requirements on the external environment, such as temperature, whether the phone is in a bright screen state, etc. In many cases, 150W fast charging does not actually charge at 150W speed. The so-called 150W fast charging is just the most ideal charging speed measured by the manufacturer under extremely ideal conditions, with low external ambient temperature and the phone being turned off.
More than 3 times of optical zoom
Have you noticed that even if the current flagship mobile phone is equipped with optical zoom function, it will not accumulate to 50x zoom or even 100x zoom like before. Because this feature cannot bring too obvious improvement in experience. High-magnification anti-shake is very sensitive to shake, and any slight shake will affect the framing and focus of the lens. Of course, if you have special shooting equipment or shooting needs, that's another matter. But the high-magnification zoom function is undoubtedly useless to most people.
Various over-the-top cooling technologies
As the performance of mobile phone processors becomes more and more powerful, the heat of mobile phones becomes more and more serious. Nowadays, when manufacturers launch new mobile phones, they without exception have to make a big deal about heat dissipation. I believe most consumers don’t understand the various cooling technologies promoted by manufacturers, but subconsciously think they are powerful.
In fact, most of the current heat dissipation technologies are similar. The heat dissipation structure is usually implemented using graphene + VC vapor chamber + silicone grease . Most mobile phones are like this, and there is no essential difference. No matter how hyped up the manufacturers are, if the processor is not good, it will not change much whether the phone should actually be hot or not. If we really want to solve the problem of mobile phone heating, we can only deal with it from the source, which is the power consumption of the processor.
Dual speakers or even four speakers
It is undeniable that dual speakers and four speakers do have a certain improvement in sensory experience compared to single speakers, but the premise is that you are a person who is sensitive to sound perception. In fact, in daily life where external speakers are used, few people have high requirements for sound quality. Because whether it is dual speakers or four speakers, the improvement in sound quality is really limited. If you want to have a significant improvement in sound quality, it is difficult to achieve it in a size as small as a mobile phone. At least it must be similar to 4 speakers on a tablet and a larger cavity.
