With the rapid development of the mobile phone market, many excellent functions have been born. These functions are not only configuration, but also the ability to take pictures. Generally speaking, it is difficult for mobile phone users who are used to new functions to return to the previous models. < / P > < p > for example, when the current mobile phone users are used to the refresh rate of 120Hz, it is difficult to return to 60Hz in subsequent use, which will visually feel stuck and affect the daily use of mobile phone users. < / P > < p > but today, let’s focus on the charging speed of mobile phone products, especially the iPhone, which has attracted many users’ attention. < / P > < p > in this fast-growing mobile phone market, the charging speed of iPhone is absolutely unique. When other manufacturers start to use charging speed above 30W, iPhone still maintains the fastest charging speed of 18W. < / P > < p > you should know that the domestic mobile phones have started to use the charging speed of 120W, and the power of 65W and 40W has been gradually popularized, and the iPhone is still much slower in this case. < / P > < p > of course, compared with the traditional 5V / 1A ancestral charger, the charging speed of today’s iPhone has become much faster, but there is a big gap compared with domestic ones. < / P > < p > in fact, when it comes to the charging speed of the iPhone, the author thinks that the battery life is more critical. In the past, the mobile phone battery can be disassembled, but the iPhone is an integrated battery. < / P > < p > at that time, the iPhone was really fast in power consumption and slow in charging. However, with the rapid development of the market, the iPhone’s endurance has improved a lot. < / P > < p > I think the weight of the battery life is much more important than the charging speed. Compared with the charging speed, people are more concerned about whether their mobile phone will run out of power at any time, and whether it can let me use it for another day. < / P > < p > of course, the reason why iPhones don’t do high-power fast charging is very simple. The first is the durability problem. The higher the charging efficiency, the shorter the battery life of the mobile phone. This is one of the reasons why the battery life of many high-power mobile phones does not work very quickly. However, it is undeniable that battery life has become the biggest headache for mobile phone manufacturers since the mobile phone battery cannot be replaced. However, after so many years, battery technology has not been substantially improved. < / P > < p > in addition to protecting the battery, the government should also have a place to control profits. The 18W charging efficiency charger for iPhone needs to be purchased from the government, and the price of this 18W fast charging charger is not low. < / P > < p > although the official said that fast charging efficiency is not good for the battery, it still launched a high-efficiency charger. After all, the capacity of the battery has been greatly increased. If the previous 5W charging speed is continued, it is still a bit unreasonable. < / P > < p > so there is a certain reason why the iPhone doesn’t use high-power fast charging. Otherwise, it must be the first time to make it. < / P > < p > compared with improving battery capacity, it is obviously better to improve the charging efficiency. At present, there are several charging schemes in the industry, such as QC scheme and PD scheme. Although the various schemes are complicated, they are still focused on “voltage V” and “current a”.
mobile phone, but professional language does not mention it. If iPhone mobile phone wants to get high power and fast charging, it should not be a particularly difficult matter. But at this stage, there may be some considerations, otherwise it will not make complaints about the Tucao sound. Skip to content
